VCU inventors' hand-held device brings vast improvements to water testing process
Elevated levels of uranium in water supplies is an environmental safety and health concern, but current methods of detecting it are cumbersome, costly and time consuming. Gary C. Tepper, Ph.D., chair of the Department of ...
Solar paint offers endless energy from water vapor
Researchers have developed a solar paint that can absorb water vapour and split it to generate hydrogen - the cleanest source of energy.
'Halos' discovered on Mars widen time frame for potential life
Lighter-toned bedrock that surrounds fractures and comprises high concentrations of silica—called "halos"—has been found in Gale crater on Mars, indicating that the planet had liquid water much longer than previously ...
Scientists develop more efficient catalytic material for fuel cell applications
Scientists at Ames Laboratory have discovered a method for making smaller, more efficient intermetallic nanoparticles for fuel cell applications, and which also use less of the expensive precious metal platinum.
Tiny 'cages' could keep vaccines safe at high temperatures
Vaccines and antibodies could be transported and stored without refrigeration by capturing them in tiny silica 'cages', a discovery which could make getting vital medicines to remote or dangerous places much easier, cheaper ...
Climate change and an 'overlooked' nutrient: silica
Among ecologists, carbon gets all the glory. Scientists examine its critical role in plant growth and decay, they chart its contributions to greenhouse gases, and they measure its sequestration in earth, sea, and sky.
New process makes hydrogels useful for more applications
Hydrogels are gelatinous amalgams of cross-linked polymers that can absorb and hold large quantities of water. Their uses vary widely. Certain hydrogels form the absorbent layer in disposable diapers, while others form the ...
Hot spring in Chile may show where to look for life traces on Mars
Two geoscientists at Arizona State University have made a discovery among hot springs in Chile that may spur scientists to revisit a location on Mars explored several years ago by NASA's Spirit rover. The discovery involves ...
Researchers find possible reason for the carcinogenicity of silica dust
Scientists from LPI RAS, Skoltech, and MIPT have discovered unusual properties of silicon nanoparticles. They have shown that at normal conditions silica nanoparticles are enriched with oxygen. Such nanoparticles are magnetic ...
