The high-temperature oxidation of propane [PDF]

Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1959
Abstract Above 400 °C propane is oxidized by a two-stage degenerately branching chain reaction. The first 20% of reaction proceeds by an HO2/C3H7 radical chain where the main immediate products are propylene and hydrogen peroxide.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Isothermal Oxidation Behavior of Cu-38at.%Zn Alloy at High Temperature

High Temperature Materials and Processes, 2011
The isothermal oxidation behavior of Cu-38at.%Zn alloy over the temperature range of 773–1123 K was studied. Characterization of the oxidized specimens was conducted using X-ray diffraction (XRD) and scanning electron microscope (SEM).

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.

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

High temperature oxidation behavior of γʹ-strengthened CoNi-base superalloys

Corrosion Communications
Oxidation behavior of γʹ-strengthened CoNi-base superalloys was investigated with isothermal oxidation tests conducted in air at 800 and 900 °C, respectively, for 100 h.

An epithelial GPR35 isoform supports tumor‐associated transcriptional and metabolic phenotypes

FEBS Letters, EarlyView.
GPR35 generates two functionally distinct isoforms with previously unresolved roles. GPR35‐short mediates immune‐cell chemotaxis, while GPR35‐long is enriched in colorectal cancer epithelium, where it supports increased metabolism, proliferation, and tumor‐associated transcriptional programs.

Improving the high-temperature oxidation resistance of CrN coating by gradient deposition considering internal stress effects

Nuclear Materials and Energy, 2023
In this study, two different CrN coatings were deposited on the surface of Zr-4 via a multi-arc ion-plating method using gradient and non-gradient deposition processes.

Nutrient/TOR signaling controls adipose mitochondrial transcription factor A (TFAM) to regulate organismal growth in Drosophila

FEBS Letters, EarlyView.
Animals must match their growth rate to available nutrients. We show that in Drosophila larvae, the nutrient‐sensing TOR kinase controls growth by regulating levels of TFAM, a key regulator of mitochondrial function, in the adipose tissue. When nutrients are abundant, high TOR activity suppresses TFAM, lowering mitochondrial bioenergetic activity and ...

High temperature oxidation of corrosion resistant alloys from machine learning

npj Materials Degradation, 2021
Parabolic rate constants, k p , were collected from published reports and calculated from corrosion product data (sample mass gain or corrosion product thickness) and tabulated for 75 alloys exposed to temperatures between ~800 and 2000 K (~500–1700 oC ...
