Fluorescent Bis(guanidine) Copper Complexes as Precursors for Hydroxylation Catalysis

Inorganics, 2018
Bis(guanidine) copper complexes are known for their ability to activate dioxygen. Unfortunately, until now, no bis(guanidine) copper-dioxygen adduct has been able to transfer oxygen to substrates.

Catalytic Hydroxylation of Polyethylenes [PDF]

ACS Central Science, 2017
Polyolefins account for 60% of global plastic consumption, but many potential applications of polyolefins require that their properties, such as compatibility with polar polymers, adhesion, gas permeability, and surface wetting, be improved. A strategy to overcome these deficiencies would involve the introduction of polar functionalities onto the ...

Enhanced Osteoconductivity of Zirconia Implants with One-Step Femtosecond Laser Treatment Through Morphological and Chemical Modifications

Journal of Functional Biomaterials
Improving surface bioactivity is crucial to acquiring zirconia implants with ideal osteoconductivity. In this work, we enhanced the surface properties of zirconia implants, specifically roughness, hydrophilicity, and osteoconductivity, using a “one-step”

Effect of Alkyl Substituents on the Hydrogen Catalytic Osmylation of Cis and Trans 2-Cyclohexene-Cyclohexanol [PDF]

Iranian Journal of Chemistry & Chemical Engineering, 1995
Catalytic osmylation of cis and trans 2-cyclohexene-cyclohexanol (1a) and (1b) are carried out in the presence of N-methyl morpholine-N-oxide. Under the same conditions, only the cis isomer reacted, leading to triol (3).

Lack of activity of recombinant HIF prolyl hydroxylases (PHDs) on reported non-HIF substrates

eLife, 2019
Human and other animal cells deploy three closely related dioxygenases (PHD 1, 2 and 3) to signal oxygen levels by catalysing oxygen regulated prolyl hydroxylation of the transcription factor HIF. The discovery of the HIF prolyl-hydroxylase (PHD) enzymes
