A typical nuclear reactor uses only a small fraction of its fuel rod to produce power before the energy-generating reaction naturally terminates. What is left behind is an assortment of radioactive elements, including unused fuel, that are disposed of...
Artificial cells that release materials when exposed to light have been embedded in a durable membrane, allowing chemical reactions to be controlled.
These structures could be used to control the synthesis of drugs in the body on demand, as well...
RUDN University chemists together with colleagues from the Chemnitz University of Technology (Germany) have synthesized the first chemical receptor that can effectively bind to cyclic guanosine monophosphate (cGMP) in an aqueous solution—cGMP regulates many physiological processes in the cardiovascular...
Scientists at TU Dresden and Hasselt University in Belgium investigated the physical causes that limit the efficiency of novel solar cells based on organic molecular materials. Currently, the voltage of such cells is still too low—one reason for their...
The search for sustainable approaches to generating new fuels has brought scientists back to one of the most abundant materials on Earth—reddish iron oxide in the form of hematite, also known as rust.
Researchers say rust has long been seen...
About a quarter of a percent of the entire gross domestic product of industrialized countries is estimated to be lost through a single technical issue: the fouling of heat exchanger surfaces by salts and other dissolved minerals. This fouling...
A group of new smart materials discovered by researchers at Texas A&M University and their colleagues has the potential to significantly improve the efficiency of fuel burn in jet engines, cutting the cost of flying. The materials, which could...
Researchers at UCLA and Columbia University have developed a novel method for tracking the activity of small molecules in the brain, including the neurotransmitters serotonin and dopamine. Pairing tiny artificial receptors with semiconductor devices that are able to function...
Alkaline water electrolysis has been touted as a path to establish a hydrogen economy by converting intermittent renewable energies into clean hydrogen-based chemical energy.
However, current technology has achieved only low current densities and voltage efficiencies.
To make electrolysis more resourceful,...
"Lego block" artificial cells that can kill bacteria have been created by researchers at the University of California, Davis Department of Biomedical Engineering. The work is reported Aug. 29 in the journal ACS Applied Materials & Interfaces.
"We engineered artificial...
Northwestern University researchers have developed a first-of-its-kind technique for creating entirely new classes of optical materials and devices that could lead to light bending and cloaking devices -- news to make the ears of Star Trek's Spock perk up.
Using...
