18/01/2019Researchers from Chalmers University of Technology, Sweden, have discovered a simple new tweak that could double the efficiency of organic electronics. OLED-displays, plastic-based solar cells and bioelectronics are just some of the technologies that could benefit from their new discovery, which deals with "double-doped" polymers.
17/01/2019Electronegativity is one of the most well-known models for explaining why chemical reactions occur. Now, Martin Rahm from Chalmers University of Technology, Sweden, has redefined the concept with a new, more comprehensive scale.
16/01/2019A new device developed by Stanford University researchers could make it easier for doctors to monitor the success of blood vessel surgery.
15/01/2019By gaining control over shape, size and composition during synthetic molecule assembly, researchers can begin to probe how these factors influence the function of soft materials.
11/01/2019Scientists from the University of Bath (UK) and Northwestern University (USA) have developed a new type of sensor platform using a gold nanoparticle array, which is 100 times more sensitive than current similar sensors.
10/01/2019Researchers from North Carolina State University have developed a new technique that allows them to assess radiation exposure in about an hour using an insulator material found in most modern electronics. The technique can be used to triage medical cases in the event of a radiological disaster.
09/01/2019Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a new integrated photonics platform that can store light and electrically control its frequency (or color) in an integrated circuit.
08/01/2019Advances in artificial intelligence have created new threats to the privacy of people's health data, a new University of California, Berkeley, study shows.
04/01/2019Tungsten carbide is one of the most versatile metal compounds and is renowned for its durability and strength, making it perfect for cutting tools, boring machines, and surgical instruments. Although its use in additive manufacturing (AM), or 3D printing, would seem ideal, tungsten carbide is susceptible to fractures and breakage when exposed to the extreme laser melting process.
03/01/2019Skin has a remarkable ability to heal itself. But in some cases, wounds heal very slowly or not at all, putting a person at risk for chronic pain, infection and scarring. Now, researchers have developed a self-powered bandage that generates an electric field over an injury, dramatically reducing the healing time for skin wounds in rats. They report their results in ACS Nano.
