Many wearable biosensors, data transmitters and similar tech advances for personalized health monitoring have now been 'creatively miniaturized,' says materials chemist Trisha Andrew at the University of Massachusetts Amherst, but they require a lot of energy, and power sources can be bulky and heavy. Now she and her Ph.D. student Linden Allison report that they have developed a fabric that can harvest body heat to power small wearable microelectronics such as activity trackers.
The Polymerisation Process research group of the POLYMAT institute of the UPV/EHU-University of the Basque Country has managed to efficiently encapsulate semiconductor nanocrystals or quantum dots of various sizes into polymer particles; great stability in terms of their optical properties and good fluorescence control when combining different quantum dots have been achieved. The possible applicability of these materials as sensors of volatile organic compounds has also been explored.
A recent study, affiliated with South Korea's Ulsan National Institute of Science and Technology (UNIST) has presented a new class of solar cells, using lead-free perovskite materials.
In biology, folded proteins are responsible for most advanced functions. These complex proteins are the result of evolution or design by scientists. Now, a team of scientists led by University of Groningen Professor of Systems Chemistry, Sijbren Otto, have discovered a new class of complex folding molecules that emerge spontaneously from simple building blocks. The results were published in the Journal of the American Chemical Society on 16 January.
The organic polymer PEDOT is probably one of the world's most intensely studied materials. Despite this, researchers at Linköping University have now demonstrated that the material functions in a completely different manner than previously believed. The result has huge significance in many fields of application.
For the first time, researchers performed logic operations -- the basis of computation -- with a chemical device using electric fields and ultraviolet light. The device and the pioneering methods used open up research possibilities including low-power, high-performance computer chips.
The discovery shows an efficiency rate that is up to 25 times higher than traditional catalysts made from larger iridium structures or nanoparticles.
By 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. Finding these answers could help advance virology, drug delivery development and the creation of new materials.
Organic polymers can nowadays be found in solar cells, sensors, LEDs and in many other technical applications. One specific type of polymers - known as S-PPVs - were previously regarded as promising in theory but were almost impossible to produce from a technical perspective. After many years of work, a team from TU Wien has now managed to identify a new chemical synthesis process for the production of S-PPVs.
Researchers 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.
