"Foldamers" are a class of synthetic structures modeled after proteins, but are designed to form unique, non-natural tertiary and quaternary structures. Like proteins, they are comprised of hydrophobic and hydrophilic subunits, ...
(Phys.org)—One thing that all chemical reactions have in common—whether they are the reactions that take place inside a battery, the metabolic reactions inside a living organism, or the combustion reactions that cause ...
(Phys.org)—Last October, researchers at Ohio State demonstrated the world's first solar battery—a solar cell and a lithium-oxygen (Li-O2) battery combined into a single device. The main attraction of the solar battery ...
(Phys.org)—By using solar energy to reversibly attach and detach hydrogen atoms on a 6-carbon ring called benzene, scientists have developed a simple and efficient method to store, transport, and release hydrogen potentially ...
(Phys.org)—Proton-exchange membrane fuel cells (PEMFCs) are lightweight fuel cells being developed for applications in vehicles and portable electronics. One of the biggest challenges facing their development is the need ...
(Phys.org)—As lithium resources continue to decline worldwide, the next generation of portable electronics will most likely be powered by something other than Li-ion batteries. One potential candidate is the sodium-ion ...
(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 ...
(Phys.org) —Hydrogels can reversibly change their size and shape under different conditions. This property makes them attractive for a wide variety of applications, including artificial muscles, drug delivery, and sensors. ...
(Phys.org) —A fundamental part of climate change response is expected to involve the discovery of advanced materials capable of cost-effectively capturing CO2 from burning fossil fuels. One particular class of materials, ...
(Phys.org) —Water is rarely pure; instead, it often contains dissolved ions or is mixed with other liquids. Scientists can change the composition of water by separating its mixtures, which is most commonly performed by ...
