Organic carbonates are an important source for polycarbonate synthesis. However, their synthesis generally requires phosgene, sophisticated catalysts, harsh reaction conditions, or other highly reactive chemicals. We present the first direct electrochemical generation of mesityl methyl carbonate by C-H activation. Although this reaction pathway is still challenging concerning scope and efficiency, it outlines a new strategy for carbonate generation.

ConspectusLithium-ion batteries (LIBs) based on graphite anodes are a widely used state-of-the-art battery technology, but their energy density is approaching theoretical limits, prompting interest in lithium-metal batteries (LMBs) that can achieve higher energy density. In addition, the limited availability of lithium reserves raises supply concerns; therefore, research on postlithium metal batteries is underway. A major issue with these metal anodes, including lithium, is dendritic formation and insufficient reversibility, which leads to safety risks due to short circuits and the use of flammable electrolytes.

Triblock Pluronics of polyoxyethylene (PEO) and polyoxypropylene (PPO) are identified as competent suppressors for copper (Cu) electroplating in advanced electronics manufacturing. However, the specific interfacial roles of PEO and PPO blocks in Pluronic suppressors, are not yet fully understood, which is crucial for the rational design of effective suppressors. Herein, the influences of composition and block arrangement of such Pluronics on the inhibition against Cu plating are systematically investigated.

Waste printed circuit boards (WPCBs) are a significant component of electronic waste (e-waste) and are among the fastest-generating waste flows. The potentially negative impacts caused by e-waste on the environment and human health pose an increasingly apparent threat to people's everyday lives and well-being. The nonmetallic fraction (predominantly carbon) of WPCBs is characterized by heavy weight, low resource value, and complex composition, and these characteristics significantly restrict the recycling of the WPCBs to achieve a circular economy.

The non-enzymatic electrochemical detection of glucose by direct oxidation using electrodes modified with suitable electrocatalysts is now well-established. However, it most often requires highly alkaline media, limiting dramatically the use of such electrodes at neutral pH. This is notably the case of Ni-based electrodes.

Biosensors are transforming point-of-care diagnostics by simplifying the detection process and enabling rapid, accurate testing. This study introduces a novel, reusable biosensor designed for direct viral RNA detection from unfiltered saliva, targeting SARS-CoV-2. Unlike conventional methods requiring filtration, our biosensor leverages a unique electrode design that prevents interference from saliva debris, allowing precise measurements.
