Rice University chemical engineer Michael Wong has spent a decade amassing evidence that palladium-gold nanoparticles are excellent catalysts for cleaning polluted water, but even he was surprised at how well the particles converted biodiesel waste into valuable chemicals.
Perovskite materials are the newest contender for breaking the silicon ceiling in solar cell technology. But they don't just absorb light. Cambridge researchers have found they emit it like a laser, opening up an entirely new field of applications.
The National Science Foundation has just awarded $200,000 to engineers at Oregon State University who have developed a new technology that they believe could revolutionize the treatment and prevention of sepsis.
Janus capsules, miniature, hollow structures, appear in different fragments composed of different micro- and nanoparticles. Theoreticians were able to design models of such capsules, but a real challenge was to produce them. Now, Janus capsules can be produced easily and at low cost.
Researchers created nanoparticles that under the right conditions, self-assemble - trapping complementary guest molecules within their structure. Like tiny submarines, these versatile nanocarriers can navigate in the watery environment surrounding cells and transport their guest molecules through the membrane of living cells to sequentially deliver their cargo.
By combining advanced mathematics with high-performance computing, scientists have developed a tool that allowed them to calculate a fundamental property of most atoms on the periodic table to historic accuracy - reducing error by a factor of a thousand in many cases.
A new mathematical model could help engineers control the formation of wrinkle, crease, and fold structures in a wide variety of materials. It may also help scientists understand how these structures form in nature.
An international team of scientists has developed a material which guides and transports a magnetic field from one location to the other, similar to how an optical fibre transports light or a hose transports water.
