After six years of intensive effort, scientists are reporting development of the first commercially viable Nano generator, a flexible chip that can use body movements — a finger pinch now en route to a pulse beat in the future — to generate electricity. This development represents a milestone toward producing portable electronics that can be powered by body movements without
In automobile catalytic converters, the surface conditions of the precious metals—the catalyst materials—have a large effect on their ability to clean emissions. Conventionally, precious metal particles are adhered to a base material. However, heat from the exhaust gas causes the particles to collect together and agglomerate to form larger particles. This reduces the surface area of the precious metals and
The graphene is a substance which has a single-layer crystal lattice of carbon atoms, which is unusual since it is different from all of the materials of its kind. Several researchers have identified a way of making this substance, which allows them to use it in various fields and especially for the high-speed electronic devices. Graphene Definition: Graphene is
Artificial photosynthesis is one of the newer ways researchers are exploring to capture the energy of sunlight reaching earth. Photosynthesis: Photosynthesis is the conversion of sunlight, carbon dioxide, and water into usable fuel and it is typically discussed in relation to plants where the fuel is carbohydrates, proteins, and fats. Using only 3 percent of the sunlight that reaches
