Participation of NO-synthase in Control of Nitric Oxide Level in Rat Hippocampus after Modelling of Ischaemic and Haemorrhagic Insult [PDF]

BioDiscovery, 2017
Electron paramagnetic resonance (EPR) was used as a method for recording the content of the nitric oxide (NO) in hippocampal tissues of intact rats and rats after modelling of ischaemic and haemorrhagic stroke.

Electron paramagnetic resonance studies of the chelate-based ionic liquid in different solvents

Green Energy & Environment, 2020
The electron paramagnetic resonance spectra of the chelate-based ionic liquid [C10mim][Cu(F6-acac)3] in different solvents have been obtained at 120 K. It was found that the values of the 63Cu hyperfine coupling constants (AIL) of [C10mim][Cu(F6-acac)3 ...

In Situ Constructed Magnetic Core‐Shell Hydrogen‐Bonded Organic Framework‐on‐Metal–Organic Framework Structure: an Efficient Catalyst for Peroxymonosulfate Activation

Advanced Functional Materials, EarlyView.
In this work, a magnetic core‐shell catalyst (HOF‐on‐Fe3O4/ZIF‐67) is successfully synthesized, consisting of a metal–organic framework (ZIF‐67) with magnetic Fe3O4 as the core and a porous hydrogen‐bonded organic framework (HOF) as the shell. The catalyst efficiently activated peroxymonosulfate, resulting in rapid and effective removal of water ...

Selective Benzene Capture by Metal‐Organic Frameworks

Advanced Functional Materials, EarlyView.
Metal‐organic frameworks (MOFs) hold significant potential for capturing benzene from air emissions and hydrocarbon mixtures in liquid phases. This capability stems from their precisely engineered structures, versatile chemistries, and diverse binding interactions.

Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions

Advanced Functional Materials, EarlyView.
This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

Pushing the sensitivity boundaries of X-band EPR cryoprobe using a fast microwave switch

Journal of Magnetic Resonance Open
We present a new design of an X-band EPR cryoprobe based on a fast microwave switch and a cryogenic low-noise microwave amplifier that are placed close to the sample in the same cryostat.

Reconfigurable Magnetic Soft Microrobot for Acoustically Triggered Targeted Bacterial Sterilization

Advanced Functional Materials, EarlyView.
Reconfigurable magnetic soft microrobots integrate in situ‐grown piezoelectric zinc oxide nanorods that produce reactive oxygen species upon acoustic excitation. Combining magnetically guided transport with thermally induced planar reconfiguration, the microrobots achieve targeted delivery and enhanced bacterial sterilization through efficient on ...
