5 Introduction Julio Cortez / Houston Chronicle Oil spills and wastewater Conventional Techniques

6 Oil Spills Clean Up BoomsBooms -- Floating barriers placed around the oil or around whatever is leaking the oil. Booms contain the oil so skimmers can collect it. SkimmersSkimmers -- Boats, vacuum machines, and oil- absorbent plastic ropes that skim spilled oil from the water's surface after booms have corralled it. The skimmer collects oil into a container so it can be removed. In-situ burningIn-situ burning -- Igniting freshly spilled oil while it's still floating on the water. Chemical dispersants Bioremediation

7 Nanowire membranes


9 Chemical composition Potassium sulphate Potassium persulphate Manganese sulphate monohydrate Solution ratio 1:2:1 in deionized water K 2 SO 4 K2S2O8K2S2O8 MnSO 4. H 2 O Transferred Teflon-vessel @ 250 0 C for 4 days in OVEN Final product: Superhydrophilic Manganese oxide nanowire membranes

10 Use of Polydimethysiloxane (PDMS) Provides silicon Silicon is hydrophobic PDMS @ 234 0 C and for 30 mins nanomembrane Final product; Silicon coated superhydrophobic membranes

11 What they have accomplished MIT engineers have developed self-assembled nanowire membranes with superwetting properties (0.05 s). By coating the membrane with hydrophobic molecules, the wetting characteristics are reversed biggest-stories-of-2008.html

12 The nanomembrane was assembled underwater and dried. SEM high magnification few of nanowire bundle under various magnification

13 Optical image of the cryptomelane membrane Scanning electron microscope image of cross section area of the membrane Later the wool-like bundle was stretched out and pressed in a similar way that paper is made.

14 What they found: Very robust Reusable Hydrophobicity doesnt decrease with use


16 Nanowire membranes act as nano-capillary sponges the pore size distribution centered about 10nm Surface area of 44 m 2 g -1

17 Membrane absorbs on average of 14 t m -3 of motor oil making it an ideal oil absorbent Experimental results shows the membrane can soak up organic substance 20 times of its weight

18 Oil uptake studies of the silicone-coated nanowire membrane ; absorption capabilities of the membrane for a selection of organic solvents and oil in terms of its weight gain


20 Comparison to porous Polypropylene and silicon-coated glass fabric membranes Manganese oxide Nanowires Polypropylene and silicon coated glass fibers Water contact angle ( Ѳ >170 ) Water contact angle 142 and 128 resp. In mixture of toluene and water, these nanowires absorb only toluene Absorbs both water and toluene selective absorption of different sizes toluene Doesnt show any notable selectivity Thermal stability up to 380 0 CNot so stable

21 Conclusions Nanowire membranes can be controlled to be either hydrophilic or hydrophobic Addition/subtraction of coating Thermodynamically stable Selective solubility Polar v. non-polar Non-polar v. non-polar

22 Applications Oil Spills Absorbs only organics Regeneration Separation Process

23 Assessment Useful technology Wide variety of applications Manganese Oxide is Toxic Manganese Oxide

24 Further Research Possibilities Membranes that are specific to one species Techniques for large-scale production Use compounds that are non-toxic Full properties of material

25 Questions?

26 Rebuttal from U1 We agree that we all need to work on our speaking skills, such as eye contact and overall verbal delivery. We should also avoid filler words. Some people thought our introduction was either too long or too short, and many people felt that it was vague and off-topic. Our intention with the introduction was to familiarize the audience with the problems of current oil spill cleanup and how nanotechnology can help out. We should have made it a little more clear and possibly improved our organization. More in-depth research could have been done by us on the hazards of such materials and similar research being done by other groups.!_by_Be rger.jpg

27 Review of Group U1s Presentation- By Group U2: -Kyle Demel -Kyle Demel -Keaton Hamm -Keaton Hamm -Bryan Holekamp -Bryan Holekamp -Rachael Houk -Rachael Houk

28 The presenters could have discussed the following more in depth: Further applications of oil- soaking nanomembranes: –Small-scale water clean-ups –Self-cleaning fabrics/carpets –Super absorbent rags –Hydrocarbon storage –Filter membranes Introduction –Needed to be longer

29 Group 3: Krista Melish James Kancewick Phillip Keller Mike Jones Super wetting Nanomembranes for Selective Absorption Review from Group U3

30 Presentation Review: Ugrad #1 Presentation ReviewMaterial Review Good Volume and Tone Need to reduce use of verbal distractors (umm, like, etc.) and pauses Slight tendency to present to the slide versus the audience Good slide design Consistent format Use of graphics enhanced presentation Well thought out and easy to follow Overall Grade: 90 Article chosen appropriate and Interesting Selective absorbance characteristics of non-polar liquids holds future value Speed and selectivity of absorbtion are astounding Holds promise for oil spill clean up Laboratory separations Industrial absorption bed material Questions for further research: What are the hazards of regeneration? Can the technology be applied to other areas such as solute adsorption (seawater) or gas adsorption (fuel storage)?

31 Review from Group 4 Group U4

32 Main Points Possible uses rely on the hydrophobicity of the membrane. Tested on a laboratory scaled and proved to absorb oil and not water. Reusable. When scaled up, could be used to clean up oil spills. Chemical properties could be modified to absorb other substances, thus broadening the range of applications. Debate over its hazardousness. Group U4

33 Nanotechnology Applications: Oil and gas industry Review of Team U1 by Team U5 – Jaynesh Shah, Greg Pudewell, Edwin L. Youmsi Pete and John Pack.

34 Oral and Quality of Slides Review The speakers did a great job of speaking in a clear manner. They were confident and sounded knowledgeable on the subject. The slides were visually appealing and consistent Graphics helped gave visuals about and helped understand the subject

35 Technical Review The presentation was technically sound Good use of technical jargon Paper selection was relevant and recent Perhaps research other new methods of cleaning up oil spills

36 The presentation was well laid out and there were illustrations to support their points. The paper presented was very innovative and possessed many potential future uses. Further research needs to be performed to determine the feasibility of large scale production. They could have spoken more clearly and made more eye contact with audience. Presented by Undergraduates 1 (U1) Critiqued by Undergraduates 6 (U6) – Pavitra Timbalia, Michael Trevathan, & Jared Walker Group U6 Review from U6 to U1

37 What We Learned Nanowire/nanomesh is: Highly hydrophobic Extremely durable Has a strong affinity toward hydrocarbons Capable of significant hydrocarbon separation – based on polarity Only been produced on small scale The cost of production is unknown Potential toxicity issues while manufacturing In the future it will be capable of efficiently cleaning up spilled oil in the field. Group U6 Review from U6 to U1

38 Mass Production It seems that the nano-capiliary sponges can be used to selectively absorb or set boundaries for and contain leaked oil. In order to make this possible, a large amount of sponges are needed. What efforts have researchers made to improve the techniques to mass-produce this nano- material? Have they been successful? How far has the research been done to commercially produce the material for use? Jung Hwan Woo Review from G6 to U1c

39 Socioeconomic Issues Is the production toxin-free? (especially for large-production) Is this material more cost-effective than the current methods discussed in the introduction? Jung Hwan Woo Review from G6 to U1c
