High C2-C4 selectivity in CO2 hydrogenation by particle size control of Co-Fe alloy nanoparticles wrapped on N-doped graphitic carbon

open access: yesiScience, 2022
Summary: A catalyst based on first-row Fe and Co with a record of 51% selectivity to C2-C4 hydrocarbons at 36% CO2 conversion is disclosed. The factors responsible for the C2+ selectivity are a narrow Co-Fe particle size distribution of about 10 nm and ...

Oxygen vacancies in Ru/TiO2 - drivers of low-temperature CO2 methanation assessed by multimodal operando spectroscopy

open access: yesiScience, 2022
Summary: Hydrogenation of CO2 is very attractive for transforming this greenhouse gas into valuable high energy density compounds. In this work, we developed a highly active and stable Ru/TiO2 catalyst for CO2 methanation prepared by a solgel method that

STRUCTURAL INORGANIC CHEMISTRY [PDF]

open access: yesNature, 1946
SINCE the first studies of crystal structures were made by the Braggs in 1913, there has been an ever-increasing flow of structure analyses carried out, first by the X-ray method alone, and later in addition by other techniques. For some time, while investigators-largely physicists-were exploring the possibilities of the new science and establishing ...

Distinctive coordination behavior of a pyrazole imine-oxime compound towards Co(II) and Ni(II)

open access: yesHeliyon, 2019
The polytopic Schiff base 5-methyl-1H-pyrazole-3-carboxylic acid 2-(hydroxyimino-1-methyl-propylidene)-hydrazide (H2L)was synthesized by the condensation of 5-methyl pyrazole-3-carbohydrazide and 3-(hydroxyimino)butan-2-one and its coordination ability ...

Dietary nitrate and nitrite protect against doxorubicin‐induced cardiac fibrosis and oxidative protein damage in tumor‐bearing mice

open access: yesFEBS Open Bio, EarlyView.
Chemotherapies such as doxorubicin can have toxic effects on healthy cardiovascular/heart tissue. Following up on a doxorubicin toxicity study in mice without tumors where nitrate water was cardioprotective (lessened toxicity), this study with tumor‐bearing mice undergoing doxorubicin treatment showed no negative effect of nitrate and nitrite on drug ...

Diabetes‐induced vascular calcification is associated with low pyrophosphate and its oral supplementation prevents calcification in diabetic mice

open access: yesFEBS Open Bio, EarlyView.
Induction of diabetes in three different mouse strains uniformly resulted in an increase in TNAP activity and a reduction in pyrophosphate (PPi) in the circulation. Inhibition of TNAP restored plasma PPi. Diabetes‐induced calcification in the media layer of the aorta was detected only in the Abcc6−/− strain, which is predisposed to ectopic ...
