Make a Solar Cell - TiO2/Raspberry based
 
07:58
In this video we show how to make a dye sensitized solar cell based on titanium dioxide and anthocyanin found in raspberries. First get some titanium dioxide (anatase structure), about 0.5g will do. Then mix it with drops of vinegar until it has the consistency of thin paint or liquid corrector fluid. Add a drop of dishwashing detergent. This is to make it stick to the glass. Now get a piece of indium tin oxide glass. The indium tin oxide glass was purchased from delta technologies http://www.delta-technologies.com/ using a multimeter set to measure resistance, find the conductive side by measuring the resistance of the glass. The side that's conductive will have a much lower resistance than the non-conductive side. Tape the glass on three sides onto a flat surface, conductive side up. there should be able 5mm of tape on each edge. The tape will serve as a spacer guide for the titanium dioxide. Now using a glass rod, apply the titanium dioxide paint to the conductive of the indium tin oxide glass. Slide the rod across the tape so that it smears the paint evenly and smoothly across the glass. If the paint leaves streaks, you need to add more vinegar and try again. It should go on with a smooth coat. Now let the slide dry on air. Then carefully peel off the tape and get the slide. Use a damp cloth to clean off any excess titanium dioxide that might have oozed around behind the slide or off the edges. Place the slide, conductive side up, on a hot-plate and heat to 200+ celsius (preferably 550 celsius). The detergent and the vinegar will burn away and bake together the particles of titanium dioxide so that they stick to the glass. At first it will turn yellow and then turn light again as this happens. The whole process takes about 20 minutes. As that happens, get some fresh raspberries (juice made from artificial flavoring cannot be used) and crush them. Now get the cooled titanium dioxide slide and pour a few drops of the raspberry juice onto it. Be careful not to damage the titanium dioxide. Let it sit for a few minutes so the anthocyanin dyes absorb into the titanium dioxide. Then carefully pour water and alcohol over the slide to wash away raspberry bits and other chemicals we don't need. Let the slide dry. Take another indium tin oxide glass slide and pass the conductive side through a candle flame several times. This will build up a layer of soot that we need to catalyze the redox shuttle. Carefully wipe away the excess soot from the edges so that they match with the titanium dioxide from the slide. Now we make the redox shuttle and electrolyte by mixing 127mg of iodine crystals with 830mg of potassium iodide and 10mL ethylene glycol. Mix thoroughly until completely dissolved. Place a few drops of the redox shuttle and electrolyte onto the titanium dioxide and place over it the soot covered slide. The coated sides must be facing each other. Be sure to offset the slides so that you can access the conductive sides of both. Bind the slides together using binder clips. And that's done. the positive side is the soot covered slide, while the negative side is the titanium dioxide slide. Use alligator clips to contact the exposed sides. The titanium dioxide (anatase type) and potassium iodide and iodine were purchased from Alfa Aesar. http://www.alfa.com

STANFORD RESEARCH: IRON OXIDE SOLAR HYDROGEN
 
00:39
research at Stanford university shows the semiconductor iron oxide (rust) can be used to create hydrogen from sunlight and water. (best if coated with nano-layer of nickel oxide) this video has iron oxide heated by solar parabolic mirror. the released hydrogen produces current in the water bath. BTW KEEEP IRON OXIDE AWAY FROM ALUMINUM!!! (THERMITE)

Energy Breakthroughs: A Glimpse into the Future
 
01:42:11
The global energy landscape is in the midst of rapid change. Threats such as climate change and energy access present challenges—but also create opportunities for new innovative approaches. As the world works to accelerate the shift away from fossil fuels, what advancements need to happen for technologies like solar to take their place cost-effectively and reliably? What will our energy storage options look like to account for distributed generation? How will the electric grid of the future support new renewable fuels and energy storage technologies? Hear from the innovators from Argonne National Lab, who are helping to bring emerging technologies from the lab to the marketplace, through a series of TED-style talks that present a glimpse into our energy future.
Titanium dioxide
 
20:58
Titanium dioxide, also known as titanium(IV) oxide or titania, is the naturally occurring oxide of titanium, chemical formula TiO 2. When used as a pigment, it is called titanium white, Pigment White 6 (PW6), or CI 77891. Generally it is sourced from ilmenite, rutile and anatase. It has a wide range of applications, from paint to sunscreen to food colouring. When used as a food colouring, it has E number E171. This video is targeted to blind users.

Stuff Matters
 
57:49
21st-century materials science is now making possible a world where buildings harvest their own energy, bridges repair themselves, clothes increase life expectancy by monitoring health. But many alternative realities are possible, each driven by different cultural and economic forces. We could find ourselves dealing with seas full of plastic, declining life expectancy, and energy black-outs. Which future will we choose? In this lecture, Professor Mark Miodownik argues that only a deeper understanding of materials science will allow us to navigate the future successfully. Professor Miodownik is a best-selling author, broadcaster, and innovative thinker who has been bringing new ideas in materials science to the general public for decades. His many awards and honors include the Communication Awards of the National Academics of Sciences, Engineering, and Medicine.
