Process and properties of rhenium powders prepared by hydrogen reduction
Rhenium powders are prepared by hydrogen reduction in tubular push-boat furnace, using ammonium perrhenate as the raw materials. The effects of ammonium perrhenate particle size, reduction temperature, hydrogen flow rate, and boat loading amount on the ...

Dynamic Processes of Rhenium Polyhydride Complexes
Studies have demonstrated that high-coordination-number rhenium polyhydride complexes are precursors to catalysts that transform a variety of organic molecules. While rhenium polyhydride complexes lead to active catalysts, little has been reported on the

Rhenium-Catalyzed Phthalide Synthesis from Benzamides and Aldehydes via C–H Bond Activation
The [4 + 1] annulation of benzamides and aldehydes for phthalide synthesis was achieved via rhenium-catalyzed C–H activation, which demonstrates an unprecedented reaction pattern distinct from those of other transition-metal catalyses.

The Chemistry of Rhenium (V) Chloride [PDF]
Reactions of rhenium(V) chloride with triphenylphosphine, triphenylphosphine oxide, and pyridine were investigated, using various solvents. It was found that both the amount of water present and the age of the rhenium(V) chloride played important roles ...

Objective High body mass index (BMI≥27 kg/m2) and aberrant gait biomechanics are primary risk factors for knee osteoarthritis (KOA), yet the specific loading patterns linked to clinical disease features remain unclear. Unsupervised machine learning (ML) was used to identify vertical ground reaction force (vGRF) waveform modes of variation and ...
