Studies on the synthesis and application of chiral materials has important scientific significance and market value. However, the design, synthesis and application of chiral materials are still in their infancy, and relevant research is limited to natural chiral polymer materials and very few artificial synthetic chiral materials.

In response to the key problems of synthesis, characterization, and mechanism research in the field of chiral materials, researchers from the Qingdao Institute of Bioenergy and Bioprocess Technology of the Chinese Academy of Sciences have proposed a novel concept of “asymmetric kinetic resolution polymerization” (AKRP), which provides a new method for the efficient synthesis, direct characterization of chiral polymer materials, and a new approach for studying the reaction mechanism of asymmetric polymerization.

The challenge in achieving AKRP is the design and synthesis of highly enantioselective catalysts. To solve this problem, the researchers proposed the “dual-ligand” strategy for the first time, enabling the highly enantioselective chiral (BisSalen)Al catalysts. The research is published in Journal of the American Chemical Society.

As part of its energy transition strategy, energy giant Shell plans to shed some of its retail locations, including gasoline stations, to focus more on EV charging sites.

“We are upgrading our retail network, with expanded electric vehicle charging and convenience offers, in response to changing customer needs,” Shell said in its 2024 Energy Transition Strategy report. The company plans to “divest around 500 Shell-owned sites (including joint ventures) a year in 2024 and 2025.” The company’s plans were first reported by Bloomberg News.

The closures will shrink the company’s retail footprint by 2.1%. In 2023, the company operated 47,000 locations.

Thanks to a significant scientific breakthrough in detection methods, conducting secret underground nuclear tests could become obsolete.

A team of Earth scientists and statisticians say they can now tell with 99 percent accuracy if such an explosion has taken place. This is up from 82 percent and is based on a dataset of known tests in the US, according to the new study published in Geophysical Journal International. It has previously been tricky to differentiate between nuclear explosions and other seismic sources, such as naturally-occurring earthquakes or man-made noise above ground.

“The explosion goes off and you have all this energy that radiates out, which can be measured on seismometers,” said lead author Dr. Mark Hoggard, of The Australian National University (ANU). “So, the science problem becomes how do we tell the difference between that and a naturally-occurring earthquake?”

The quest for boundless energy takes an electrifying turn with this magic mineral.

Researchers have developed a revolutionary sensor capable of detecting chemical warfare agents without wires, representing a major advancement in technology for public safety. This innovative device, capable of identifying substances like dimethyl methylphosphonate (DMMP), offers a new level of efficiency and reliability in monitoring and responding to chemical threats, without the need for direct power sources or physical connections.

The urgent need for advanced detection of chemical warfare agents (CWAs) to ensure global security has led to the development of a novel gas sensor. This sensor is distinguished by its rapid response, high sensitivity, and compact size, crucial for the early detection of CWAs. Accurate detection and monitoring of CWAs are vital for effective defense operations, both military and civilian. Due to the hazardous nature of CWAs, research is typically limited to authorized laboratories using simulants that mimic CWAs’ chemical structure without their toxic effects.

Boffins show less platinum may be needed for long-lived power source.

De-risking the Welchau play in Austria may not just be a big step toward Austrian energy independence, it may also ease Europe’s $800 billion energy crisis.

Until recently, researchers were unsure of the minimum thickness of a transparent substance required to take in a given quantity of light.

Konstantin N. Rozanov of the Institute for Theoretical and Applied Electrodynamics in Russia discovered more than two decades ago the amount of light that a gadget might absorb at various wavelengths if one side of it was coated in metal. This metal establishes a barrier where light is absorbed or bounced back, simplifying the mathematical solution.
