Researchers have developed a new form of high-performance solar photocatalyst based on the combination of the TiO2 and other “metallic” oxides that greatly enhance the visible light absorption and promote more efficient utilization of the solar spectrum for energy applications.
By creating nanoparticles with a controlled shape, researchers believe smaller, more powerful and energy efficient batteries can be built. By modifying the size and shape of battery components, they aim to reduce charge times as well.
Researchers have demonstrated a method for using a lab-on-a-chip device and a cellphone to determine a concentration of molecules, such as HIV RNA molecules, in a sample.
Researchers have created a new type of molecular motor made of DNA and demonstrated its potential by using it to transport a nanoparticle along the length of a carbon nanotube.
Researchers have engineered the first self-healing battery electrode, opening a new and potentially commercially viable path for next-generation lithium-ion batteries for use in electric cars, cell phones and other devices.
A new study may point the way to improving the fatigue resistance of monolithic bulk glasses. It found that a bulk metallic glass based on palladium displayed a fatigue strength as good as the best composite bulk metallic glasses and comparable to regular polycrystalline structural alloys, such as steel, aluminum and titanium.
A new study has found that tumor cells with mutated p53 can be made much more vulnerable to chemotherapy by blocking another gene called MK2. In a study of mice, tumors lacking both p53 and MK2 shrank dramatically when treated with the drug cisplatin, while tumors with functional MK2 kept growing after treatment.
Researchers have developed an inexpensive device that uses light to split water into oxygen and clean-burning hydrogen. The goal is to supplement solar cells with hydrogen-powered fuel cells that can generate electricity when the sun isn't shining or demand is high.
Researchers have created tiny protein tubes named after the Roman god Janus that may offer a new way to accurately channel drugs into the body’s cells.
As the Fukushima crisis continues to remind the world of the potential dangers of nuclear disposal and unforeseen accidents, scientists are reporting progress toward a new way to detect the radioactive materials uranium and plutonium in waste water.
Researchers, studying more effective ways to convert woody plant matter into biofuels, have identified fundamental forces that change plant structures during pretreatment processes used in the production of bioenergy.
A new study on cocaine details how it may permanently damage proteins in the body. That information, gleaned from laboratory tests, could be used to potentially detect the drug in biofluids for weeks or months— instead of days— after use.
Semiconductors, the foundation of modern electronics, could become even more versatile as researchers make headway on a novel, inexpensive way to turn them into thin films.
Engineers and cardiology experts have teamed up to develop a fingernail-sized biosensor that could alert doctors when serious brain injury occurs during heart surgery.
A new chapter has been opened in our understanding of the chemical activity of nanoparticles, according to a team that used X-rays to reveal an unexpected property of widely used nanoparticles.
Chemical engineers have designed tiny particles that can “steer” themselves along preprogrammed trajectories and align themselves to flow through the center of a microchannel, making it possible to control the particles’ flow through microfluidic devices without applying any external forces.
A computational method to quantify the adsorption of gas by porous zeolites should help labs know what to expect before they embark upon slow, costly experiments.
On the continental margins, where the seafloor drops hundreds of meters below the water’s surface, low temperatures and high pressure lock methane inside ice crystals. Called methane hydrates, these crystals are a potential energy source, but they are also a potential source of global warming.
Artificial materials based on simple synthetic polymers can disrupt the way that bacteria communicate with each other.
The Food and Drug Administration is seeking a rule change to allow generic drugmakers to quickly update their warning labels with new safety information for doctors and patients.
Fans of "Mexican Coke" in the U.S. need not worry about losing the cane sugar that sweetens their favorite drink.
