Monovalent anion perm-selective membranes (MAPMs) combined with electrodialysis can simultaneously realize the efficient separation of mono-/di-valent anions and the concentration of monovalent salt. However, their applications in practical industrial scenarios are limited due to the low anion selectivity of commercial MAPMs, especially the poor alkali stability.

As if fentanyl isn't bad enough, a series of opioid receptor agonists called nitazines is making its way into the street drug supply. But is this because the chemicals used to make fentanyl are now more difficult to obtain? It's certainly possible, if not likely. Organic chemists are nothing if not versatile.

Polycyclic aromatic hydrocarbons (PAHs) are a type of organic molecule that carry fused rings made of the chemical benzene. Scientists believe that PAHs are responsible for chemical processes that eventually lead to soot and other carbonaceous nanoparticles on Earth and around and between the stars in deep space. On Earth, PAHs form in part because of the incomplete combustion of coal, oil, and other substances and…

Molecules offer enormous capacity for information storage. Here, the authors show that information can be encoded into molecules with sequences of paramagnetic lanthanide ions, and decoded using nuclear magnetic resonance spectroscopy.

From life-saving drugs and synthetic polymers to diverse advanced materials, the products containing organic compounds seem endless, thanks in part to regioselectivity, a feature in chemical reactions where a substituent is selectively added to a specific position of an organic compound. This favors the formation of desired products with specific functionalities.

Chinese scientists have recently achieved the direct synthesis of high-purity benzaldehyde chemicals from the selective electrooxidation of benzyl alcohol. The organic-solid-water (OSW) three-phase reaction system has shown particular advantages in reducing ohmic losses and simplifying product separation and purification processes compared to conventional H-type electrochemical cells.

Professor Fu Yao and Associate Professor Lu Xi from the University of Science and Technology of China (USTC) have conducted a cobalt-hydride-catalyzed enantioselective hydroalkylation, enabling the efficient construction of chiral tertiary carbon centers at the benzyl position. The study has been published in Nature Synthesis.

Alkenes represent one of the most abundant classes of organic molecules, which are available in bulk quantities from petroleum and renewable resources, with various utilization in agrochemistry, pharmacy, and organic materials. Typically, the transformation of alkenes by cleavage of both the σ bond and π bond underpins a range of industrial processes and provides methods for the reconstruction of hydrocarbon…
