Graphene substrate improves the conductivity of carbon nanotube network
Scientists have combined graphene and single-walled carbon nanotubes into a transparent hybrid material with conductivity higher than either component exhibits separately.
Read moreAtomic-level imaging could offer roadmap to metals with new properties
A team of researchers at the Georgia Institute of Technology has developed a new process that could help gain new insights into high-entropy alloys and help characterize their properties.

Researchers have used the method of single-particle spectroscopy to study electroluminescence in light-emitting devices. They discovered that efficient charge funneling between individual perovskite nanocrystals and the phenomenon of emission blinking are responsible for the low efficiencies of perovskite light-emitting devices.
Read moreA new strategy for the synthesis of complex natural products
Chemists have succeeded in synthesizing two complex natural products from the group of dithiodiketopiperazines (DTPs). For this, they employed a new strategy based on ''C-H bond activation,'' resulting in a short and high yielding route. The researchers describe their new concept for the total synthesis of Epicoccin G and Rostratin A.
Read moreNew capsule can orally deliver drugs that usually have to be injected
MIT engineers designed a drug capsule that can carry insulin or other protein drugs and protect them from the harsh environment of the gastrointestinal tract. When the capsule reaches the small intestine, it breaks down to reveal dissolvable microneedles that attach to the intestinal wall and release drug for uptake into the bloodstream.
Read moreStabilizing multilayer flows may improve transportation of heavy oils
During the past 20 years, the oil industry has begun to transition away from light oils toward heavier oils. But transporting heavy oils cost-effectively is a challenge because heavy oils are viscous — essentially a thick, sticky and semifluid mess. One way to outmaneuver this problem is a viscoplastic lubrication technique. It can complement existing methods to stabilize interfaces within multilayer flows.
Read moreA close up on the real world: Atomic migration under ambient conditions
Researchers have reported an environmental transmission electron microscopy technique that has allowed in situ visualization of the atomic changes of a metal surface in an electric field under ambient conditions. The activation of oxygen gas molecules by electron tunneling was found to result in atomic migration that could be followed progressively. It is hoped that the tunneling-electron-attached-gas process will provide valuable insight for the development of nanoparticle catalyst and quantum material applications.

Engineers are advancing what researchers know about hypersonic flight. A new study describes a series of tests that elucidate the conditions a future aircraft may experience traveling faster than 10 times the speed of sound.
Read moreThe science Of Breaking Bad: Would you know if meth was cooked inside your house?
Researchers analysed the contamination levels in household items from a home suspected to have previously been used for cooking methamphetamine, to determine whether surface wipe samples can adequately establish contamination and define the health risks. Results demonstrate methamphetamine has continued to mobilise after manufacture for a period exceeding five years when the property was under new ownership.
