Human devices, from light bulbs to iPods, send information using electrons. Human bodies and all other living things, on the other hand, send signals and perform work using ions or protons.
Waseda University researchers have developed a new method for producing hydrogen that is fast, irreversible, and takes place at much lower temperatures using less energy. This innovation is expected to contribute to the spread ...
Heat has always been a problem for fuel cells. There’s usually either too much (ceramic fuel cells) for certain portable uses, such as automobiles or electronics, or too little (polymer fuel cells) to be efficient.
In this post-industrialization age, electricity has become the backbone of our society. However, using fossil fuels to generate it is not the best option because of their limited availability and harmful nature. In the last ...
(Phys.org) -- An international team of researchers has discovered how adding trace amounts of water can tremendously speed up chemical reactions—such as hydrogenation and hydrogenolysis—in which hydrogen is one ...
Electron movement—what scientists call electron transfer—powers many of life's functions. For example, a good deal of the energy we derive from the foods we eat is captured by a process that removes electrons from food ...
Outbursts of energetic particles that hurtle out from the sun and can disrupt space communications may be even more varied and numerous than previously thought, according to results from the closest-ever flyby of the sun.
(Phys.org)—Photosynthesis – the ubiquitous yet remarkable process by which most plants, algae, and cyanobacteria convert light energy into chemical energy – provides the atmospheric oxygen and organic compounds fundamental ...
Researchers from New York University and the Max Planck Institute in Stuttgart reveal how protons move in phosphoric acid in a Nature Chemistry study that sheds new light on the workings of a promising fuel cell electrolyte.
(Phys.org)—As long as the temperature is above absolute zero, gas molecules are always in constant random motion. They may diffuse—or spread out—through three-dimensional space or, in a process called "surface diffusion," ...
