Mechanism of methanol and formaldehyde emissions from methanol-fueled engines

Fuel Processing Technology
Methanol, as a low-carbon fuel, has broad application prospects in engines. The mechanism of methanol and formaldehyde was investigated respectively in a methanol premixed combustion test bench (PCTB) and a 304 stainless-steel flow reactor (SFR). The results of PCTB indicate that methanol cannot escape from the flame surface to form unburned methanol ...

Effect of methanol use in the engine on the workflow

IOP Conference Series: Materials Science and Engineering, 2020
AbstractIn the Vyatka GSHA for a number of years, research has been conducted on the conversion of internal combustion engines to work on methanol. The purpose of our research is to improve the efficiency and environmental friendliness of the 2CH 10.5/12.0 diesel engine when working on methanol using a dual-fuel feed system (DST) and the use of a multi-

NAPRT loss promotes lung tumor initiation and growth through AKT signaling independently of NAD+ biosynthesis

Molecular Oncology, EarlyView.
Loss of NAPRT promotes lung tumor initiation and growth through a noncanonical mechanism, independent of its role in NAD+ biosynthesis. Mechanistically, NAPRT depletion activates the mTORC2‐driven AKT/β‐catenin signaling axis to enhance clonogenic and invasive phenotypes. Furthermore, lung‐specific Naprt deletion significantly increases tumor burden in

Yeast Gcn2 retains activity following humanization of its auto‐phosphorylation region

FEBS Open Bio, EarlyView.
Using Saccharomyces cerevisiae as a model to study Gcn2 activation and regulation is limited by the lack of antibodies detecting phosphorylated Gcn2. To overcome this, we engineered Gcn2‐HsC, a yeast Gcn2 variant recognizable by commercial anti‐human phospho‐GCN2 antibodies.

Identifying and characterising a plant GH1 β‐glucosidase that exhibits hydrolytic activity on N‐linked glucopyranoside

FEBS Open Bio, EarlyView.
We report the first β‐glucosidase with demonstrated hydrolytic activity on an N‐linked glycopyranoside. The enzyme, native to maize, was biochemically characterised for this novel reaction, and structural modelling of the enzyme–substrate complex revealed several clues to the underlying reduced catalytic rate relative to its native O‐glycopyranoside ...
