m-Nitrovinylbenzene was chemoselectively reduced to m-aminovinylbenzene in a suspension of a TiO(2) photocatalyst in the presence of a hole scavenger at room temperature under atmospheric pressure without the use of a precious metal or reducing gas, and nitrobenzenes having other reducible groups were also chemoselectively reduced to corresponding aminobenzenes.

Reductive direct substitution of α-arylvinyl triflates on the sp carbon atom by magnesium in the presence of chlorosilane proceeded to give the corresponding α-silylstyrenes, which could not be reduced further, and the reaction completely stopped because the reduction potential of α-silylstyrenes lies out of the reducible field of magnesium. The subsequent reduction of α-silylstyrenes by calcium brought about the second introduction of another silyl group to the vicinal carbon atom to lead a selective and simple route to a variety of 1,2-disilanes from vinyl triflates by cooperative works of magnesium and calcium with different reduction potentiality.

Nanozyme-based sensors for detecting ascorbic acid (AA) generally depend on the reducibility of the analyte. However, these sensors are susceptible to interference from reducing substances in food. Herein, a novel fluorescent sensor for AA detection was developed based on inhibiting the phosphatase-like activity of a Zr-based metal-organic framework (Zr-CAU-28).

Background Numerous classifications exist for intertrochanteric (IT) fractures, commonly focused on stability. However, the currently utilized Arbeitsgemeinschaft Osteosynthesefragen and Orthopaedic Trauma Association (AO/OTA) classification has limitations in identifying irreducible fractures. This study aims to answer the following questions: does fracture stability imply irreducibility; which fracture fragments complicate reduction; and which reduction techniques should be employed? Materials and methods Eligibility criteria included fractures in adult long bones without pathological fractures being treated by native conservative means.

The integration of textile-based sensing and actuation elements has become increasingly important across various fields, driven by the growing demand for smart textiles in healthcare, sports, and wearable electronics. This paper presents the development of a small, smart dielectric elastomer (DE)-based sensing array designed for user control input in applications such as human-machine interaction, virtual object manipulation, and robotics. DE-based sensors are ideal for textile integration due to their flexibility, lightweight nature, and ability to seamlessly conform to surfaces without compromising comfort.
