New methodology for the synthesis of benzazepines

Benzazepines can be found in a wide variety of natural products and pharmaceuticals. Many of these compounds are chiral, being available in two enantiomeric forms. The synthesis of benzazepines with chiral stereocenters represents ...

Report highlights decline of insect taxonomists across Europe

While insect populations continue to decline, taxonomic expertise in Europe is at serious risk, confirms data obtained within the European Red List of Insect Taxonomists, a recent study commissioned by the European Union ...

New strategy proposed for ultra-long cycle lithium-ion battery

In recent years, lithium-ion batteries have been widely used in many fields. Compared with traditional lithium ion battery cathode materials, more lithium ions in lithium-rich manganese-based cathode materials of unit mass ...

Tiny flakes tell a story of tool use 300,000 years ago

When prehistoric people re-sharpened cutting tools 300,000 years ago, they dropped tiny chips of flint—which today yield evidence of how wood was processed by early humans. The small flint flakes were discovered at the ...

An X-ray step towards superfast nanoelectronics

When a material with magnetic properties, constructed from appropriately selected layers, is illuminated by a pulse from an X-ray laser, it instantly demagnetizes. This phenomenon, so far poorly understood, could in the future ...
