1Group S1 RebuttalMost of the comments were positive, which were appreciated.Of the negative comments, while we agree with most, the ones we don’t agree with was our shortened introduction. We believe that our topic was a continuation of the solar cell discussion Dr. Seminario gave on the first day of class, and therefore a long introduction was not needed.Group S1
2Group S2: Review of Solar Technology Chris HeflinRachael HoukMichael Jones
3PositivesGroup S1 was the first to present, and therefore had a harder time knowing what to expect with the presentation. However, they presented a professional, well organized presentation.Each presenter was knowledgeable on their respective areas of the topic, spoke clearly and fluently.
4NegativesThe group should make use of the microphones and vocal projection in order to be well heard. Everything was very quiet.Many of the slides contained only words and no pictures, making the presentation less interesting.Some of the material was a bit more technical than most were prepared for. A bit more introduction would be beneficial.
5Group S3: Review of Solar Technology Bradford LambMichael KoettingJames KancewickWeek 1 Additional SlidesSeminarGroup S3
6recommendationsWe felt S1 should have had more detailed background slides towards solar technology.The information that they presented was somewhat lost on the audience because it was too detailed without having a solid background.Thus, we attached two additional slides that improve background knowledge.Group S3
7General KnowledgeSolar powered electrical generation relies on heat engines and photovoltaicslimited only by human ingenuitymost common way is to use solar panelsPassive solar or active solarGroup S3
8WATER TREATMENT used to make saline or brackish water potable Solar energy may be used in a water stabilization pond to treat waste water without chemicals or electricityGroup S3
9Group S4 Review of Solar Cell Technology Joshua MorenoScott MarwilDanielle MillerGroup S4
10Things Done WellThe group created a very nice power point that was full of good visuals and rich informationThe group spoke very clearly and made minimal use of words like “um.”The group presented the material in a fun and interesting way.Group S4
11Things That Need Improvement The group needs to try to not fit so much information on every slide. The slides got a bit wordy in some areas.The group needs to develop the introduction a little bit more. We felt like it was too short and did a poor job of leading into the material.Group S4
12Group 5 Pradip Rijal Jason Savatsky Trevor Seidel Laura Young Group S5 Review of Solar Cell TechnologyGroup 5Pradip RijalJason SavatskyTrevor SeidelLaura YoungGroup S5
13Presentation Review The group overall did a very good job. They talked about the use of DSSC and Quantum Dots being used in Solar Cells but they did not tell us what they were.Organization was satisfactory.Could work on speaking louder.Group S5
14Group S6: Review of Solar Technology Critiqued by S6Michael TrevathanDaniel ArnoldMichael TranJohn BaumhardtGroup S6
15SummaryDiscussed new solar cell efficiencies resulting from nanotechnologyNeeded to discuss the feasibility of this technology becoming a substantial source of energyNeeded more analysis on cost – at least some estimated ranges based on the materialThey all dressed nicely and spoke clearlyThey were knowledgeable and directed their attention toward the audienceOverall – great presentation!Group S6
16Chris Heflin Rachael Houk Mike Jones Group S2 rebuttalChris HeflinRachael HoukMike Jones
17Data used showed amine needed to be replaced slowly with a fresh stream because some of it leaves in the tail gas streamNo info available on the cost of the nano-porous membrane to compare with traditional methodsThe presentation was right after Dr. Seminario did a harsh critique of a previous presentation, so there was reason to be nervous, but we should have rehearsed more.
18Thanks for the feedback on the animation and introduction Thanks for the feedback on the animation and introduction. We’ll try to continue this practice in our future presentations.

22Group S3 Review: nanoporous membranes Michael KoettingBradford LambJames Kancewick
23ReviewThe presentation was informative and the slides were generally well done.Student questions were answered confidently and in detail.Presentation was not too detailed to be understandable by the audience, yet still detailed.
24ReviewSpeaking could have been more polished, with more eye contact from some of the speakers and less reading from slides/notes.Some figures in the slideshow were not explained, so they added very little to the presentation.Despite this, however, the presentation was very good on the whole.
25Scott Marwil Danielle Miller Joshua Moreno Group S4Review of Nano Membranes for Gas SeparationScott MarwilDanielle MillerJoshua MorenoGroup S4
26Things Done WellVery good job with the illustrations and the animationsThe group did a good job of answering the classes questions in a full and in-depth mannerThe group members presenting knew the material and did an good job relaying that knowledge onto the rest of the classThe Group was very well spokenThey made good use of animations and pictures to illustrate pointsTheir introduction was very thorough and well writtenThe material was presented in an interesting and exciting wayGroup S4
27Things That Need Improvement The overall presentation was a little on the short side.The group needs to develop a better introduction to introduce the topic and background to the class instead of just jumping to the heart of the material so quicklySometimes the slides contained a bit too much information. They should try limit the amount of information on the slides so they can draw attention to the speaker.The Not-So-GoodGroup S4

29Presentation ReviewThe groups power presentation and visuals were very well done.They probably should have practiced the presentation a little more. The oral presentation was weak and unfocused.Their attire was appropriate for the occasion.Group S5
30John Baumhardt Daniel Arnold Michael Trevathan Michael Tran Group S6Review of Nano Membranes for Gas SeparationJohn BaumhardtDaniel ArnoldMichael TrevathanMichael Tran
31Review Slide layout was agreeable and pleasant to look at. The presentation was detailed and well thought out.The further research section is a little weak (the natural gas composition could have included a sample composition of “actual natural gas”The presentation overall was quite good, but the presenters seemed a little nervous, and were reading off of the slides.
32Review of InformationFrom a natural gas background, the disadvantages listed are not valid. In an amine system, there are no chemicals stored on site because there are very few reasons to change the amine. Apart from wanting to try a more efficient amine, standard amine reclamation (cleaning) can be performed to regenerate the existing amine.Even without regeneration, amine lasts years in plants without replacement.We would have liked a cost comparison of the nano-porous membranes vs the traditional amine, to determine the commercial viability of the membranes in gas plants.
33Group S3 Rebuttal On the whole, comments were generally very positive. Most negative comments centered on the presentation having too much info on some slides. The topics discussed were very information dense and thus mandated a lot of details be presented; however, we agree that some slides could have been split up into two slides for easier viewing.
34Review of Nanotechnology Use in Delivery of Chemicals Group S1Review of Nanotechnology Use in Delivery of ChemicalsGroup S1
35Notes on Presentation Positive Notes Opportunities for ImprovementJames was very enthusiastic and interested in topicGood use of modelThe slide on chemotherapy was very educationalMichael was very knowledgeable on background chemistryNeed more background informationIntroduction was too shortToo much text on some slidesInformation was goodNeeds to be spread outGroup S1
36Review of Nanotechnology Use in Delivery of Chemicals Group S2Review of Nanotechnology Use in Delivery of ChemicalsChris HeflinRachael HoukMike Jones
37The GoodReally liked the use of the fruit to demonstrate the principlesLots of pictures that helped explain the topicPresenters appeared enthusiastic and knowledgeable
38The Not-So-Good No mention of further research areas Failed to address toxicityCould mention that the paper didn’t talk about the fruit produced, only the plant during gemination
39Scott Marwil Danielle Miller Joshua Moreno Group S4Review of Nanotechnology Use in Delivery of ChemicalsScott MarwilDanielle MillerJoshua Moreno
40Things Done WellVery good job with the illustrations and the animations especially the model about the nanotubes that was presentedThe group did a good job of answering the classes questions in a full and in-depth mannerThe group members presenting knew the material and did an good job relaying that knowledge onto the rest of the class
41Things That Need Improvement The overall presentation was actually very good and not a lot of improvements are neededOne thing I do think needs changing is that the conclusion wasn’t that good. The introduction was fantastic but the conclusion left the listener hanging. The questions did help wrap things up though and the group presenting did a good job answering questions.

43Presentation ReviewThe groups power presentation and visuals were very well done.The oral presentation was solid and it was very easy to understand them.The group clearly learned from other groups mistakes and was able to not make the same mistakes.Some of the slides were a little wordy and detracted from the oral presentation.
44Review of Nanotechnology Use in Delivery of Chemicals Group S6Review of Nanotechnology Use in Delivery of ChemicalsPresented by S3Critique by Group S6Michael Trevathan, Daniel Arnold, John Baumhardt, and Michael Tran
45SummaryIt was creative to use straws and fruits to demonstrate how carbon nano-tubes are used in the agricultural industryIt was excellent to discuss more than one application for a single technology: medicinal applications and agricultural applications.The use of pictures and graphs were very well done and they were a great supplement to the text.The negative impact on humans resulting from the use of nanoparticles in agriculture should have been discussed.
46SummaryThere was too much information on each Dextran slide to be able to understand all the information.It was difficult to read the axes on some of the graphs – they could have been placed on their own slide.Overall, it was a very insightful and educating presentation.

48Presentation: Nanotechnology in the Oil and Gas Industry By Group 4 Group S1REVIEW of Nanotechnology in the Oil and Gas IndustryPresentation:Nanotechnology in the Oil and Gas IndustryBy Group 4
49Positive Notes Josh had good speaking skills Slides had good format Seemed knowledgeableGood paceSlides had good formatLarge text, except for first slideLots of graphicsUse of humor in end question slidePresenters answered questions with further information than what was presentedShowed good preparation for presentationBut the presentation was information-light, so adding the info to the slides would have been helpfulTwo group members managed well in the absence of third member
50Opportunities for Improvement Scott can improve speaking skillsRushed paceLooked at monitor more than audienceSeemed like the group could not find adequate information for presentationLittle detail in slidesA different topic choice where information was more available would have been betterSlide information was not cited in slides or at end of presentationPictures were not cited either

52REVIEW of Nanotechnology in the Oil and Gas Industry Group S2REVIEW of Nanotechnology in the Oil and Gas IndustryChris HeflinRachael HoukMichael Jones
53PositivesVery good at building slides with both pictures and words. Graphs gave good representation of the information.Provided multiple applications of the technologies available and delved into each topic.Spoke clearly and eloquently.
54NegativesThe presentation was a bit brief. They could elaborate more on each topic rather than moving steadily through the slides.
55Michael Koetting James Kancewick Bradford Lamb Group S3REVIEW of Nanotechnology in the Oil and Gas IndustryMichael KoettingJames KancewickBradford Lamb
56Overall Good explanations of slides Good time management Expanded on topicsNano robot discusion very interesting
57Recommendations Have more information/ slides about the topics Better time managementMore pictures

59Presentation Review The presentation needed more graphics Some of the slides were just wordsThe oral presenters spoke clearly and were easy to understandSome of the slides were a little wordy and detracted from the oral presentationThe topic was well developed and interesting to the audience
60Presentation ReviewThe team presented the information well and understood the topic thoroughlyThe oral presentation was good; they spoke clearly and slowly—easy to understand
61John Baumhardt Daniel Arnold Michael Trevathan Michael Tran Group S6REVIEW of Nanotechnology in the Oil and Gas IndustryJohn BaumhardtDaniel ArnoldMichael TrevathanMichael Tran
62ReviewProfessional slide layout and, except for a couple graphics, the graphic text sizing was easy to read.The presentation was very professional and the interest/passion felt for the topic was evident throughout the presentation.The verbal presentation was quite good overall. There was some reading straight off of the slides, which was distracting.For some of the topics, we felt, while the nanotechnology research was interesting, the shortcomings of the current industrial methods were not explicitly established.
63Critique of Information We are afraid the actual drive for anti-corrosion technology was missed in the presentation.From a natural gas background, the anti-corrosion section doesn’t address the corrosion aspect of the natural gas industry. In the industry, corrosion refers to the degradation and destruction of pipelines internal walls.Whenever untreated natural gas (from a well) travels through a pipe line microbes accumulate throughout the pipeline, and some produce sulfur that corrodes the pipeline.Nanotechnology solutions are most likely focused on internal pipeline corrosion rather than low impact sea water, rust, and paint degradation.
64Critique (continued)We believe that our concerns with the presentation are due to the incorporation of too many subtopics.There were so many applications discussed that a clear/in-depth analysis couldn’t possibly have been performed for the background section of every topic.This topics were extremely interesting and the nanotechnology information seemed very well researched and established.

66Group 1 Evaluation of Group 5 Presentation:Carbon NanotubesBy Group 5
67Positive Notes The introduction was very solid Good information was presentedInitial animated graphics quickly grabbed the audience’s attentionThe first half of the presentation used slides that were easy to read and follow.Showing the summary charts of the positive and negative processes for creating carbon nanotubes was helpful as a quick comparison guide.
68Opportunities for Improvement Each of the speakers, especially the third, used too many “filler” words, such as “um”.The third speaker was clearly nervous in front of the audience. It made his presentation very dry, uninteresting, and detracted from the first two presenters.The text used in second half of the presentation began to get crowded. More slides with fewer words per slide would’ve been helpful.
69Grade Slides (19/20) Educational Value (20/20) Graphics (19/20) Well designed, but very basic in appearance.Educational Value (20/20)A lot of research was presented in a very clear and understandable manner about a new field.Graphics (19/20)Use of 3-D animation was greatMade presentation more enjoyableBut replace a few pictures with diagramsOral presentation (16/20)1st speaker did well3rd speaker was extremely nervous and unpreparedGroup Analysis of Research (20/20)It was evident that plenty of research was done to give a very thorough presentation.Overall (94/100)
70Group S2 Review of Carbon Tubes Chris HeflinRachael HoukMichael Jones
71Positives The first two speakers spoke clearly and eloquently. The slides had both pictures and words, with graphics providing good insight into the intricacies of the process.The group was well prepared and answered questions well.
72NegativesThe third speaker read his material directly off of the slide the vast majority of the time. Also, almost every sentence contained an “Um”The second speaker spoke quickly and moved swiftly through the slides, she could have elaborated more and allowed more time for the material to sink in.
73Group S3 Review of S5—Carbon Nanotubes James KancewickMichael KoettingBradford Lamb
74PositivesThe introduction to the topic was simple and easy to understand, while providing enough background to follow the presentation.The slides appeared well-made and did not present too much information at any one time.The first two speakers did a good job speaking on their respective topics and were easy to follow.
75Areas for ImprovementThe third speaker appeared unrehearsed and mostly read off the slides in an uninspired manner. More rehearsal would have helped improve the presentation greatly.The comments about safety needed some sort of research information to back up the concerns.Sometimes the presentation was moved along a little too quickly, especially with charts and graphs.
76REVIEW of Carbon-Nanotubes Group S4REVIEW of Carbon-Nanotubes
77S4 Review of S5 Presentation Group S4REVIEW of Carbon-NanotubesS4 Review of S5 Presentation
78Things Done WellDid a good job of defining any technical terms used throughout the presentation.Had a nice basic informative introduction that allowed the audience to follow along in the presentation.Did an excellent job of explaining graphics.Laura and Travis had good eye contact and projection.
79Things to Improve OnGraphics in the first half of presentation had citations, but toward the end of presentation there were absolutely no citations for the graphics used.What article were you critiquing?Some slides were too wordy, but overall most of the slides had a nice layout.
80Things To improve OnJason- Your part of the presentation contained the most interesting topics, but you were so nervous that it was hard to follow along…..Relax! Have confidence in what you are going to say and look up.Laura- use a transition or at least a statement to introduce new slides; you just read the title of the slide and proceeded to talk about the body of the slide.
81Group S6 REVIEW of Carbon-Nanotubes John BaumhardtDaniel ArnoldMichael TrevathanMichael Tran
82ReviewGood color scheme for a professional presentation; however, formatting on each slide was not consistent (text sizing and bullet use).The presentation went into impressive detail on the synthesis of nanotubes. There is too much text on the application slides.Most of the group spoke very well. We would recommend that the last speaker work on his public speaking. Public speaking is not learned over night, and is an important skill to possess.Overall, it was a very interesting in the presentation.
83Critique of Information During the presentation, we would have liked to have the information on the strength of nanotubes (slide 5) explained more thoroughly. The slide was changed before we realized the numbers given were ratios.There should have been a slide concluding all of the types of synthesizing nanotubes. Comparing and contrasting the multiple methods would have helped tie the information together.When presented with the multiple applications that carbon nanotubes have, it was hard to determine which ones were practical, and in what timeframe we would expect to see them in use.The slide on reactivity did not add anything to the presentation and was not tied in to the overall presentation.
84Critique (continued) Our main concerns are that: There was not any real connections between each of the synthesis methods (compare and contrast).No timetable or discussion on the practicality of nanotube application.Information was not always tied into the topic. Extraneous information was given.It is clear that this group extensively researched their topic, and concise organization of the material would have served to emphasize this aspect to a greater extent.

87Positive Notes Good speaking skills overall Slides had good format All speakers seemed knowledgeable and well-researchedSlides had good formatMany pictures that were referenced during the presentationThe pictures really made the topic tangiblePresenters answered questions with further information than what was presentedShowed good preparation for presentationOrganization of the presentation was goodEach presenter covered an important section and spoke about the same lengthClear transitions between the presentation parts
88Opportunities for Improvement Some of the slides had too many factsWe were reading the slides instead of listening to the speakersLast speaker needed more elaborationHe also had choppy sentencesThe transition between the third and fourth section was jarringConclusion slide at the end of the third section was misleadingSudden switch from interior to exterior coatings was not adequately explained

91Review of S6—Nanotechnology in Industrial Applications By Group S3:James KancewickMichael KoettingBradford Lamb
92Things Done WellThe speaking was very good through all parts of the presentation. The presenters all seemed very knowledgeable within their respective sections.The use of statistics within the presentation was good at providing a scope for the topics discussed.Slides looked very professional throughout the presentation.Use of graphics instead of words in several places made for a more interesting presentation.Introduction was very good at introducing the topics and the reasons for the research.
93Areas for ImprovementThe slides covering heat transfer equations with fouling were not necessary given the audience (chemical engineering students), were boring, and added nothing to the presentation.On the whole, this was a very good presentation, with very few negative aspects.

100Review of S1—Nanotechnology in Agriculture By S3:James KancewickMichael KoettingBradford Lamb
101ReviewThe first and third sections of the presentation were easy to understand and the speakers did a good job of explaining the material.The second section of the presentation (endosulfan experiment) was difficult to follow; the slides also contained numerous spelling and formatting errors, and the graphs were not labeled well.Endosulfan experiment should have been explained in layman’s terms instead of with purely scientific numbers and no explanation of the implications of the findings.
102Review Text and graphics were occasionally too small. Applications of nanobarcodes in agriculture were not sufficiently detailed for this presentation’s topic.Slide formatting was sometimes haphazard; more parallel slide design would have made the presentation much more professional.

105Presentation ReviewThe presentation had a good balance between graphics and wordsSome of the presenters were easy to understand while others were not as clearThe presentation seemed did not flow from one section to the next making it hard to pay attentionThe introduction failed to tie the different topics together
106Presentation ReviewThe topics were not well connected or well developed, with the second topic containing far to many graphs making the presentation hard to followExperiment detailed in slides should have come before its conclusions/summary in slides 14,15.
107Nanotechnology in Agriculture (S1) Critique CHEN 481 Critique by S6:John BaumhardtDaniel ArnoldMichael TrevathanMichael Tran
108ReviewThe slide templates looked professional. The colors used made the slides easy to read.The slides should be more uniform – the font, layout, text size all varied drastically from slide to slide.Good use of pictures, however there should have been more pictures and less text – we are too lazy to read.The text was too small on many of the slides to read from the back of the room.Make research graphs fill an entire slide and explain them more thoroughly – this is our first time seeing the graph.
109ReviewNeeded a better explanation of the benefits of red shift to the agriculture.The barcode section was off topic comparatively to the other sections.The crop improvement research needed a conclusion and application slideGood job using multiple articles that were broadly discussed – you were able to encompass more of the agriculture industry.Overall good technical presentation.
110ReviewAll the speakers spoke clearly and confidently. It appeared as though they had practiced prior to the presentation.Everyone dressed nicely and took the presentation seriously.Limited amount of filler words used.Great job orally.If you read off the slides use the monitor instead of the projector so you don’t turn your body away from the audience

116Presentation ReviewThe third speaker did not seem very knowledgeable on the topic.The third speaker also seemed to read from the slides.One of the graphics was stretched out on the presentation slide. It looked like they didn’t take time to put it together—rushed.
117Presentation ReviewThe first two speakers did a very good job. They spoke slowly and clearly and were easy to understand.The presentation content was very interesting and well developed.The areas discussed were relevant to the audience, which helped to keep interest.
118S6 CHEN 481 2nd Presentation by S3 Review John BaumhardtDaniel ArnoldMichael TrevathanMichael Tran
119ReviewSlide layout was agreeable and pleasant to look at most of the time, there are some slides with dead space that should have been utilized.The presentation was detailed and well thought out.The presentation was very segmented between the group members, which results in an absence of presentation flow among the members.The presentation overall was quite good, and the audience was acknowledged frequently (good eye contact).
120Critique of Information The research seemed very broad and encompassing, we would like to have seen a more in depth analysis of the material. Example: instead of telling us that nanotechnology use leads to higher profit, show a side by side comparison of profit before and after nanotechnology applications.Even with the segments, the addition of a section with a real-world application slide was great. We like to see the actual use of this research.We would recommend more time and space be devoted to this real-world application. This is the most interesting part of any presentation for future engineers and we felt that it should have been the presentation focus.
