Researchers at the University of Tsukuba introduced a new type of porous crystal that can indicate the presence of moisture based on a reversible change in color. This research may open the way for many new gas sensors in industrial applications.
In a paper published in NANO, a team of researchers from Xinjiang University, China have prepared Au@CDs photocatalyst with core-shell structure by combining coal-based carbon dots (CDs) with gold sol. This has far-reaching significance for the further development of coal resources to prepare high-performance materials.
The air around us is still getting more and more polluted. No wonder many scientists strive to find a way to purify it. Thanks to the work of an international team led by prof. Juan Carlos Colmenares from the Institute of Physical Chemistry, Polish Academy of Sciences, we are a big step closer to achieve this goal. They found a way to make an efficient reactive adsorbent able to purify the air from various toxic compounds, cheaply, and effectively.
Universitat Rovira i Virgili researchers have developed a nanometric-scale theoretical model to create structures that kill bacteria by using elastic forces. The results of this study pave the way to creating new antibacterial materials.
Researchers developed biomaterial-based inks that respond to and quantify chemicals released from the body or in the environment by changing color. Multiple inks can be screen printed onto clothes or even face masks at high resolution, providing a detailed map of human response or exposure
Japanese researchers have succeeded in catalytic asymmetric iodoesterification from simple alkene substrates and carboxylic acids. Published in Angewandte Chemie International Edition on April 27, this new research, was accomplished by precisely controlling multiple interactions in a single catalytic reaction. This synthetic reaction is expected to contribute to the simplification of industrial processes and greater efficiency in optical active drug production.
NIST Scientists used UV light and glow powder to study the way small amounts of drug residue get spread around a forensic chemistry lab when analysts test seized drugs. Their study, recently published in Forensic Chemistry, addresses safety concerns in an age of super-potent synthetic drugs like fentanyl, which can potentially be hazardous to chemists who handle them frequently.
A technology to further accelerate the commercialization of Colloidal Quantum Dot(CQD) Photovoltaic(PV) devices, which are expected to be next-generation photovoltaic devices, has been developed.
In a Science Policy Forum, lead author Sam Weiss Evans joins more than a dozen biosecurity practitioners and analysts in calling for a new approach to biosecurity governance, grounded in experimentation. Developing an ability to rethink and test assumptions about biology, security, and society is vital to evolving biosecurity for the 21st Century. This means being systematic in governance design, periodically reassessing based on lived experience, and learning across biosecurity environments.
Did coronavirus mutate from a virus already prevalent in humans or animals or did it originate in a laboratory? As scientists grapple with understanding the source of this rapidly spreading virus, the Grunow-Finke assessment tool (GFT) may assist them with determining whether the coronavirus outbreak is of natural or unnatural origins.
