Influence of Organized Turbulence on OH Reactivity at a Deciduous Forest

Geophysical Research Letters, 2023
Oxidation of reactive carbon fuels climate‐ and pollution‐relevant chemistry. Deciduous forests are important sources of reactive carbon (particularly isoprene).

Acute Liver Failure Induces Glial Reactivity, Oxidative Stress and Impairs Brain Energy Metabolism in Rats

Frontiers in Molecular Neuroscience, 2020
Acute liver failure (ALF) implies a severe and rapid liver dysfunction that leads to impaired liver metabolism and hepatic encephalopathy (HE). Recent studies have suggested that several brain alterations such as astrocytic dysfunction and energy ...

Glass-ceramic sealants and steel interconnects: Accelerated interfacial stability and reactivity tests at high temperature

Materials & Design, 2021
High-temperature reactions between glass–ceramic sealants and Fe-Cr alloy interconnects may lead to the formation of undesirable phases, and consequently degradation of solid oxide fuel/electrolyser devices.

Evolution of NO₃ reactivity during the oxidation of isoprene [PDF]

Atmospheric Chemistry and Physics, 2020
In a series of experiments in an atmospheric simulation chamber (SAPHIR,1 Forschungszentrum Jülich, Germany), NO3 reactivity (kNO3) resulting from the reaction of NO3 with isoprene and stable trace gases formed as products was measured directly using a ...

Influence of operating conditions and fuel properties on nanostructure of soot particles from diesel engine

Nihon Kikai Gakkai ronbunshu
The influence of engine operating conditions and fuel properties on the graphite crystallite size of soot particles from a small DI diesel engine were experimentally investigated. To examine the effect of aroma content in fuel on the graphite crystallite,

OH reactivity and concentrations of biogenic volatile organic compounds in a Mediterranean forest of downy oak trees [PDF]

Atmospheric Chemistry and Physics, 2016
Total OH reactivity, defined as the total loss frequency of the hydroxyl radical in the atmosphere, has proved to be an excellent tool to identify the total loading of reactive species in ambient air.

Heterogeneous catalysis with encapsulated haem and other synthetic porphyrins: Harnessing the power of porphyrins for oxidation reactions

Open Chemistry, 2018
Encapsulated metalloporphyrins have been widely studied for their use as efficient heterogeneous catalysts, inspired by the known catalytic activity of porphyrins in haemoproteins.

Atmospheric oxidation in the presence of clouds during the Deep Convective Clouds and Chemistry (DC3) study [PDF]

Atmospheric Chemistry and Physics, 2018
Deep convective clouds are critically important to the distribution of atmospheric constituents throughout the troposphere but are difficult environments to study.

Effect of DFPP on Ferroptosis in Peripheral Blood CD14+ Monocytes of Hyperlipidemic Patients Involving the ACSL4/LPCAT3/ALOX5 Pathway

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Hyperlipidemia is a major risk factor for atherosclerotic cardiovascular disease (ASCVD). Although statins are the cornerstone of lipid‐lowering therapy, their use may be limited in some patients by adverse effects. This study evaluated the possible impact of non‐drug treatment using double‐filtration plasmapheresis (DFPP) on CD14+

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.
