Magnetorheological (MR) viscoelastic fluid, consisting of micronsized soft magnetic carbonyl iron (CI) particles and polyisobutylene (PIB)/polybutene (PB) medium matrix instead of commonly used oil ...

Carbonyl complexes of radioactive transition metals can be easily synthesized with high yields by stopping nuclear fission or fusion products in a gas volume containing CO. Here, we focus on Mo, W, ...

Noncovalent interactions define and modulate biomolecular structure, function, and dynamics. In many protein secondary structures, an intimate interaction exists between adjacent carbonyl groups of ...

Carbonyl-iron (CI)-based magnetorheological (MR) fluid containing submicron-sized additive particles was prepared. The flow behavior at a steady shear mode was investigated by comparing flow ...

The Polar Grit X2 packs all the key features you need for adventurous activities into a smaller watch that’s more affordable than the likes of the Garmin Fenix 8 and Polar Grit X2 Pro.

Three sets of conserved polarity proteins — the partitioning defective (PAR), Scribble and Crumbs complexes — regulate polarization processes in many different cell types and organisms ...

The polar regions drive global climate, environmental dynamics and even human evolution — and have done so for millions of years. This helps to explain why the poles are so crucial to policy ...

Acetaldehyde, furfural and acrolein were also reported at low levels (concentrations lower than LOQ of the method: 1.5, 1.4 and 1.0μg L-1 and higher than LOD: 0.8; 0.5 and 0.7μg/Lin 57, 71 and 76% of ...

British rockers Queen, American jazz icon Herbie Hancock, and Canadian soprano and conductor Barbara Hannigan were honored as recipients of the 2025 Polar Music Prize at Grand Hotel in Stockholm ...

This article delves into reverse polarity protection circuits built around standard and Schottky diodes, as well as high-side P-channel and N-channel MOSFETs. It also offers design ideas on how to ...
