Hydrogen Reduction Reduction (HRR)
ECS Meeting Abstracts, 2023The year 2023 marks the bicentennial of the discovery of heterogeneous H2 catalysis. Nowadays, the hydrogen oxidation reaction (HOR), which converts H2 to protons (H+), is one of the most important transformations in energy research. Meanwhile, hydrogenation reactions, which transfer net H-atoms (H·) to organic substrates from H2, play pivotal roles

Reductive Capacity of Natural Reductants
Environmental Science & Technology, 2002Reductive capacities of soil minerals and soil for Cr(VI) and chlorinated ethylenes were measured and characterized to provide basic knowledge for in-situ and ex-situ treatment using these natural reductants. The reductive capacities of iron-bearing sulfide (pyrite), hydroxide (green rust; GR(SO4)), and oxide (magnetite) minerals for Cr(VI) and ...

Fetal Reduction has been employed over the past two decades as a mechanism to reduce the morbidity and mortality of multiple pregnancies. Utilization of the procedure has increased dramatically as IVF has become commonplace but the average starting number has decreased with the transfer of fewer embryos. Success rates from fetal reduction have improved

Reduction cranioplasty can greatly improve the quality of life for selected patients with severe macrocephaly and can significantly diminish some of the difficulties in the long-term chronic care of others. Because of differences in age, cranial morphology and surgical goals, the surgical plan must be tailored to the individual patient.

Reduction malarplasty is one of the common aesthetic procedures performed in the Orient, although it is rarely performed in the West. Previously described techniques for malar reduction include shaving the prominent portion and contouring the outer surface of the malar complex utilizing a variety of surgical approaches.

Reductive Groups are Geometrically Reductive
The Annals of Mathematics, 1975Let G be a semi-simple algebraic group over an algebraically closed field, k. Let G act rationally by automorphisms on the finitely generated k-algebra, R. The problem of proving that the ring of invariants, RG, is finitely generated originates with the invariant theorists of the nineteenth century.
