Hydrogen could be an important source of clean energy, and the cleanest way to produce hydrogen gas is to split water into hydrogen and oxygen. But the catalyst currently used to facilitate this water-splitting reaction is platinum. And that’s a problem.
It may be possible to develop a simple blood test that, by detecting changes in the zinc in our bodies, could help to diagnose breast cancer early.
Scientists have shown how advanced computer simulations can be used to design new composite materials. Nanocomposites, which are widely used in industry, are revolutionary materials in which microscopic particles are dispersed through plastics.
Engineers at Lancaster University are working on powering future giant leaps for mankind. They are major partners of a consortium working on a new project to maximize "energy harvesting" on a space craft of the future.
Using one of the most powerful lasers in the world, researchers have accelerated subatomic particles to the highest energies ever recorded from a compact accelerator.
Scientists in a lab used a powerful laser to re-create what might have been the original spark of life on Earth. The researchers zapped clay and a chemical soup with the laser to simulate the energy of a speeding asteroid smashing into the planet.
Scientists from the Spanish National Cancer Research Centre (CNIO), have developed a method for producing biological crystals that has allowed scientists to observe— for the first time— DNA double chain breaks.
Large-scale storage of low-pressure, gaseous hydrogen in salt caverns and other underground sites for transportation fuel and grid-scale energy applications offers several advantages over above-ground storage, says a recent Sandia National Laboratories study.
The Homestake Mine, a played-out gold mine in Lead, S.D., that has been converted into a warren of underground chambers housing physics experiments that need to be shielded from cosmic radiation. One of these experiments is the Lux detector, designed to detect WIMPs (weakly interacting massive particles).
Researchers at the University of Pennsylvania have now shown an important commonality that seems to extend through the range of glassy materials. They have demonstrated that the scaling between a glassy material’s stiffness and strength remains unchanged, implying a constant critical strain that these materials can withstand before catastrophic failure.
During the 2014 R&D 100 Awards event, R&D Magazine expanded the banquet to hold four technology panels during the day. The last panel of the day focused on energy/environmental solutions and the innovation behind four R&D 100-winning technologies and the complexity of bringing such technologies to the market.
A laboratory at Purdue Univ. provided a critical part of the world's first transistor in 1947—the purified germanium semiconductor—and now researchers here are on the forefront of a new germanium milestone. The team has created the first modern germanium circuit—a complementary metal–oxide–semiconductor (CMOS) device—using germanium as the semiconductor instead of silicon.
One of the reasons cancer is so deadly is that it can evade attack from the body's immune system, which allows tumors to flourish and spread. Scientists can try to induce the immune system, known as immunotherapy, to go into attack mode to fight cancer and to build long lasting immune resistance to cancer cells. Now, researchers have developed a non–surgical injection of programmable biomaterial to do so.
The same research team that developed the first laser based on a living cell has shown that use of fluorescent proteins in a solid form rather than in solution greatly increases the intensity of light produced, an accomplishment that takes advantage of natural protein structures surrounding the light-emitting portions of the protein molecules.
Massachusetts Institute of Technology chemists have devised a new way to wirelessly detect hazardous gases and environmental pollutants, using a simple sensor that can be read by a smartphone. These inexpensive sensors could be widely deployed, making it easier to monitor public spaces or detect food spoilage in warehouses.
