Quantitative assessment of CT attenuation of different materials used in 3D printed models of aortic dissection for developing patient-specific 3D printed aorta models to simulate type B aortic dissection.
The capacity of lithium-ion batteries decreases over time partly due to the degradation of the binder that protects the graphite anode. To address this problem, scientists from the Japan Advanced Institute of Science and Technology are investigating a new copolymer binder that can preserve the capacity of the anode at 95% of its original value even after >1700 charge cycles. Their findings can significantly enhance battery life for electric vehicles, artificial organs, and consumer electronics.
Using thin films -- no more than a few pieces of notebook paper thick -- of a common explosive chemical, researchers from Sandia National Laboratories studied how small-scale explosions start and grow.
* Natural compound found in catnip is at least as effective as synthetic insect repellents such as DEET * Catnip can easily be grown in a home garden and made into oil or extract * New type of deterrent targets pain receptors in insects while maintaining no impact on humans
In a paper published in ACS Sustainable Chemistry & Engineering, researchers from the Kleij group present a new route to prepare biobased polyesters with tuneable properties. The researchers are building upon the multifunctional structure of the terpene β-elemene: three double bonds which have distinct reactivity, allowing to selectively transform these bonds and thus tweaking the functionalities in the backbone of the polymer.
Aqueous free-radical precipitation polymerization is one of the most useful methods to prepare the uniformly sized microgels, and an understanding of the polymerization mechanism is crucial to control the structure or physicochemical properties of microgels. However, the details of the mechanism of precipitation polymerization remain unclear. Researchers clarify the formation mechanism of microgels during precipitation polymerization by evaluating structural evolution and thermoresponsiveness of developing microgels during the polymerization and by visualization of polymerization directly.
A team of researchers led by Professor Monica Olvera de la Cruz developed a theoretical model to design a soft material that demonstrates autonomous oscillating properties that mimic biological functions, like heartbeat.
Osaka University researchers virtually screened over 200,000 pairs of molecules for use in photovoltaic cells based on a machine learning algorithm, and synthesized a device predicted to have high efficiency. This work may lead to advances in the discovery of new functional materials.
Rutgers scientists for the first time have pinpointed the sizes of microplastics from a highly urbanized estuarine and coastal system with numerous sources of fresh water, including the Hudson River and Raritan River.
Chemical engineering researchers have developed a new catalyst that significantly increases yield in styrene manufacturing, while simultaneously reducing energy use and greenhouse gas emissions.
