Aerogel Aerogel holds 15 entries in the Guinness Book of Records, including “best insulator”, and “lowest-density solid”. Sometimes called “frozen smoke”, aerogel is made by the supercritical drying of liquid gels of alumina, chromia, tin oxide, or carbon. It’s 99.8% empty space, which makes it look semi-transparent. Aerogel is a fantastic insulator — if you had a shield of aerogel, you could easily defend yourself from a flamethrower. 2.
Carbon nanotubes are chains of carbon held together by the strongest bond in all chemistry, the sacred sp 2 bond, even stronger than the sp 3 bonds that hold together diamond. 3. “Metamaterial” refers to any material that gains its properties from its microscopic structure rather than bulk composition. 4. We’re starting to lay down thick layers of diamond in CVD machines, hinting towards a future of bulk diamond machinery. 5. Diamonds may be strong, but aggregated diamond nanorods (ADNRs) are stronger. 6. 7. 8. 9. 10. TEM Sample. Learn Science at Nature.

Gelcoats are special resins that are designed to form the first surface of a composite mould or part.
Gelcoats are generally applied as a thickness of 0.3-0.7mm and are specially formulated to provide the part or mould surface with properties such as resistance to UV (ultraviolet) degradation, hydrolysis or osmosis (where water is absorbed into a composite over considerable time). Gelcoats also include thixotropic additives to make them thicker and more able to stick to inclined surfaces of moulds. Epoxy gelcoats are based on epoxide resin and polyamine hardener (just like epoxy resin) and should be used when making parts using epoxy resin , if a gelcoat surface is required. Gelcoats are applied to a mould surface and allowed to cure to a certain point before the first layer of laminate is applied. Tooling Gel Coats Tooling gel coats are specially designed to provide a highly polish-able and durable surface to epoxy based moulds.
How to Make a Carbon Fiber Car Bonnet/Hood - Part 2/3. A bright idea to help bike riders be seen and not harmed. Designer Wouter Walmink:"One of the things we wanted to do was to make a helmet that was more exciting to look at".
WOUTER Walmink never considered wearing a bicycle helmet until he moved to Melbourne a year ago. But after pedalling through the city's hectic streets, the Dutch designer realised he was going to need a helmet - so he set about making a better one. The result is the LumaHelm, a flashing headpiece with 104 multicoloured LED lights that illuminate like indicators when a cyclist tilts the head left or right. ''One of the things we wanted to do was make a helmet that was more exciting to look at,'' the 28-year-old says.
''We saw an opportunity where we thought no one had seen it before.'' Advertisement The LumaHelm is based on a standard helmet fitted with lights powered by AA batteries and a sensor that measures movement of the cyclist's head. An Arduino microcontroller placed in the cyclist's pocket translates those movements into light patterns. email@example.com. Cool Sound and Water Experiment! Quantum Levitation Is Real And It's Spectacular! Video. Singapore scientists create world's smallest gear. Confirmed by ETH Zurich study: nuclear energy phase-out is possible.
Restructuring the energy system without nuclear power by 2050 is in principle technologically possible and economically manageable.
However, it will demand a concerted effort by the whole of society. This is the conclusion reached by ETH Zurich researchers in a study they presented at the Energy Talks 2011. Over the past few months, a group of researchers at the Energy Science Center (ESC) of ETH Zurich have carried out an intensive examination of whether the available options will enable Switzerland to scope out a medium-term energy future without nuclear power, as decided by the Swiss Federal Council in May. Their answer was «yes». However, a step-by step restructuring of Switzerland’s energy systems during the coming years and decades will require great efforts by all areas of society.
No relaxations in climate targets Hydroelectric power and new renewable energy sources Higher efficiency for system components Seizing the opportunity for re-industrialisation. How to make a beta cell divide. An ETH Zurich research team-in collaboration with Roche Pharmaceuticals- has discovered a hitherto unknown mechanism by which the insulin producing beta cells are negatively affected.
This raises new hopes for pharmacologically stimulating these cells to divide and thus combating diabetes. Bace1 is by no means an unknown enzyme. It is the protease cleaving the amyloid protein in the brain and is thereby significantly contributing to the pathogenesis of Alzheimer’s disease. About its close relative Bace2, however, we for a long time merely knew that it is not involved in this disease, as it is barely present in neurons. But now a research group led by Markus Stoffel, professor for Metabolic Diseases at The Institute of Molecular Systems Biology, ETH Zurich, has found both a “home” and a function for this orphan: The enzyme is primarily present in pancreatic beta cells and regulates the proliferation of this cell type.

7 Mad Science Experiments You Can Do At Home But Probably Shouldn't. By the time you finish reading this article, you will undoubtedly think of Theo Gray when you hear someone say "mad scientist. " Theo, a columnist for the magazine Popular Science, recently published a book titled Theo Gray's Mad Science: Experiments You Can Do At Home - But Probably Shouldn't . The book is full of experiments so outrageous (Ignite your own phosphorus sun in a globe filled with pure oxygen! Make your own shotgun ammo by pouring molten lead off the roof! Heat a hot tub with 500 pounds of quicklime!) Behind the gorgeous photos of each experiment, there is solid science explained in clear, accessible language with a little dash of humor that made Theo's monthly PopSci column so popular. 1.
