10 Interesting Futuristic Materials 1. 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. 2. Carbon nanotubes are chains of carbon held together by the strongest bond in all chemistry, the sacred sp2 bond, even stronger than the sp3 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. Amorphous metals, also called metallic glasses, consist of metal with a disordered atomic structure. 7. A superalloy is a generic term for a metal that can operate at very high temperatures, up to about 2000 °F (1100 °C). 8. 9.
home Epoxy Gel Coat 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.
Jobs at Nonprofits, Jobs at Foundations 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. 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. Mr Walmink says his invention could improve cyclist safety. henrietta.cook@theage.com.au

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
Home - Tracking Your Publications Of course you can always maintain a list of your publications manually, but you also want to know how the world sees your work. The best way to do this is to use a database; the Web of Knowledge, for instance, allows you to cover a wide range of topics. Be sure to select the All Databases tab. This will include items in MEDLINE, the database behind PubMed. (You can also collect your references directly in PubMed; see this tab for details.) In the Author search box, enter your name in the format last name first initial* (e.g. smith a*). Results are listed in reverse chronological order. There are several possibilities; the most likely is that your name is entered differently in different journals. As you go through lists, put checkmarks in the boxes next to the items that are yours. . Now that you have a list that is hopefully complete and accurate, you want to save it.
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. Bace2, just like Bace1, is a cellular pair of scissors, a so-called membrane protease. Beta cells are essential for the regulation of blood sugar levels in the body. Beta cells prosper without the protease To test the hypothesis that the inactivation of this membrane protease would be beneficial, the team analyzed genetically modified mice that lack active Bace2. RNA interference sheds light on Bace2 Tmem27 may very well not be the only target of Bace2. Bace2, important for keeping the balance? Literature:
