Insight into the pyrolysis kinetics of cellulose, xylan and lignin with the addition of potassium and calcium based on distributed activation energy model

, 2022
The pyrolysis kinetics of three components of biomass (cellulose, xylan and lignin) with the addition of potassium and calcium were investigated by thermogravimetric analysis (TGA) and distributed activation energy model (DAEM).

Effect of the solvent type and polymerization conditions on the curing kinetics, thermal and viscoelastic performance of poly(amide-imide) resins

eXPRESS Polymer Letters, 2015
Isothermal and non-isothermal curing kinetics of both N-methyl-2-pyrrolidone (NMP) and N-methylimidazole (MI) based poly(amide-imide) (PAI) resins were investigated by DSC analysis using tightly closed high-pressure crucibles. Several exothermal peaks on

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

FEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Role of Vanadium Addition on Hot Deformation Behavior of Aluminum Alloy 5083

Metals, 2019
The effect of V addition on the hot deformation behavior of AA5083 was investigated. Single axial compression tests were conducted on the cast and homogenized samples with strain rates ranging from 0.01 to 10 s−1 and deformation temperatures ...

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

FEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.
