Consumers aren't embracing electric cars and trucks, partly due to the dearth of charging stations required to keep them moving. Even the conservation-minded are hesitant to go electric in some states because, studies show, if fossil fuels generate the electricity, the car is no greener than one powered with an efficient gasoline.
A Florida State Univ. engineering professor has developed a new highly efficient and low-cost light-emitting diode (LED) that could help spur more widespread adoption of the technology. Asst. Prof. of Industrial and Manufacturing Engineering Zhibin Yu developed the new LED technology using a combination of organic and inorganic materials.
A new method of manufacturing glass could lead to the production of “designer glasses” with applications in advanced photonics, whilst also facilitating industrial scale carbon capture and storage. An international team of researchers, writing in Nature Communications, report how they have managed to use a relatively new family of sponge-like porous materials to develop new hybrid glasses.
Before Ibuprofen can relieve your headache, it has to dissolve in your bloodstream. The problem is Ibuprofen, in its native form, isn't particularly soluble. Its rigid, crystalline structures make it hard to dissolve in the bloodstream. To overcome this, manufacturers use chemical additives to increase the solubility of Ibuprofen and many other drugs, but those additives also increase cost and complexity.
A molecular system that holds great promise for the capture and storage of carbon dioxide has been modified so that it now also holds great promise as a catalyst for converting captured carbon dioxide into valuable chemical products. Researchers with Lawrence Berkeley National Laboratory have incorporated molecules of carbon dioxide reduction catalysts into the sponge-like crystals of covalent organic frameworks (COFs).
We only have one example of a planet with life: Earth. But within the next generation, it should become possible to detect signs of life on planets orbiting distant stars. If we find alien life, new questions will arise. For example, did that life arise spontaneously? Or could it have spread from elsewhere? If life crossed the vast gulf of interstellar space long ago, how would we tell?
Neuroscientists know that some connections in the brain are pruned through neural development. Function gives rise to structure, according to the textbooks. But scientists at the Virginia Tech Carilion Research Institute have discovered that the textbooks might be wrong.
Cell mechanics are considerably more complex than previously thought and may affect cell structures at various levels. This finding is based on a collaborative research project conducted by an international research team from ETH Zurich and Univ. of Tampere, involving Teemu Ihalainen, a postdoctoral researcher at the Academy of Finland.
Physicists at the Univ. of Basel succeed in synthesizing boron-doped graphene nanoribbons and characterizing their structural, electronic and chemical properties. The modified material could potentially be used as a sensor for the ecologically damaging nitrogen oxides, scientists report in Nature Communications.
Researchers at Princeton Univ. have developed a dual catalyst system that directly installs alkyl groups onto compounds called heteroarenes. The new reaction uses simple and abundant alcohols and offers a milder and more widely applicable alternative to existing strategies.
Compounds found in purple potatoes may help kill colon cancer stem cells and limit the spread of the cancer, according to a team of researchers. Baked purple-fleshed potatoes suppressed the growth of colon cancer tumors in petri dishes and in mice by targeting the cancer's stem cells.
A luminescent solar concentrator is an emerging sunlight harvesting technology that has the potential to disrupt the way we think about energy: It could turn any window into a daytime power source.
Scientists have developed a new fuel cell catalyst using earthly abundant materials with performance that is comparable to platinum in laboratory tests. If commercially viable, the new catalyst could replace platinum in electric cars powered by fuel cells instead of batteries, which would greatly extend the range of electric vehicles and eliminate the need for recharging.
Rice Univ. scientists have made a living circuit from multiple types of bacteria that prompts the bacteria to cooperate to change protein expression. The subject of a new paper in Science, the project represents the first time the Rice researchers have created a biological equivalent to a computer circuit that involves multiple organisms to influence a population.
Each spring, powerful dust storms in the deserts of Mongolia and northern China send thick clouds of particles into the atmosphere. Eastward winds sweep these particles as far as the Pacific, where dust ultimately settles in the open ocean. This desert dust contains, among other minerals, iron, an essential nutrient for hundreds of species of phytoplankton that make up the ocean’s food base.
