β-Glucose 1-phosphate (βGlc1P) is a donor substrate in the synthesis of various α-glucosides by glycoside phosphorylases belonging to the glycoside hydrolase family 65. This study presents an efficient synthesis of βGlc1P combining enzymatic phosphorolysis of inexpensive maltose and baker's yeast fermentation to bias the equilibrium toward maltose phosphorolysis by removing released glucose. Mass production of βGlc1P was obtained in a 2 L reaction mixture initially containing 500 mM maltose and inorganic phosphate, with a yield of 76 %. βGlc1P was isolated from the reaction mixture by crystallization after electrodialysis to obtain 181 g of βGlc1P as a bis(cyclohexylammonium) salt.

Sodium salt of aryl sulfinic acid reacts with enynone in a different manner, yielding α-furyl sulfone and stereodefined vinyl sulfone in toluene and EtOH respectively in the presence of ZnCl. The salient features of this protocol include chemoselectivity, broad substrate scope, high efficiency, high yield, and easy purification. The synthetic utilities of the products are demonstrated by cycloaddition and cis-trans photoisomerization reactions.

Half-metallic magnetism, characterized by metallic behavior in one spin direction and semiconducting or insulating behavior in the opposite spin direction, is an intriguing and highly useful physical property for advanced spintronics because it allows for the complete realization of 100% spin-polarized current. Particularly, half-metallic antiferromagnetism is recognized as an excellent candidate for the development of highly efficient spintronic devices due to its zero net magnetic moment combined with 100% spin polarization, which results in lower energy losses and eliminates stray magnetic fields compared to half-metallic ferromagnets. However, the synthesis and characterization of half-metallic antiferromagnets have not been reported until now as the theoretically proposed materials require a delicate and challenging approach to fabricate such complex compounds.

Realization of a sustainable hydrogen economy in the future requires the development of efficient and cost-effective catalysts for its production at scale. MXenes (MX) are a class of 2D materials with 'n' layers of carbon or nitrogen (X) interleaved by 'n+1' layers of transition metal (M) and have emerged as promising materials for various applications including catalysts for hydrogen evolution reaction (HER). Their properties are intimately related to both their composition and their atomic structure.

Nanometric solid solution alloys are utilized in a broad range of fields, including catalysis, energy storage, medical application, and sensor technology. Unfortunately, the synthesis of these alloys becomes increasingly challenging as the disparity between the metal elements grows, due to differences in atomic sizes, melting points, and chemical affinities. This study utilized a data-driven approach incorporating sample balancing enhancement techniques and multilayer perceptron (MLP) algorithms to improve the model's ability to handle imbalanced data, significantly boosting the efficiency of experimental parameter optimization.
