Improvement of particulate matter emission from biomass pellet fuel combustion by adding pulping effluent during preparation

Fuel Processing Technology
Low particulate matter(PM) emissions are a research hotspot pursued in biomass fuel fields. Herein, pulping effluent, an industrial byproduct of the pulping industry, was employed to prepare biomass pellet fuel by combining with reed residue through ...

A minimal cellulosome‐like system in Cellulosilyticum lentocellum

FEBS Open Bio, EarlyView.
Cellulose‐degrading bacteria typically use cellulosomes, large multi‐enzyme complexes on a scaffold protein. In Cellulosilyticum lentocellum, we characterise a far smaller arrangement, a single scaffold bound to one cellulase through a single cohesin‐dockerin interaction.

Synergistic effects of side-chain functional groups in lignin pyrolysis: Roles of Cα oxidation and Cβ substitution

Fuel Processing Technology
To elucidate the intrinsic mechanistic roles of side-chain functionalities, four lignin dimer model compounds were synthesized to differ in the oxidation state at the Cα position (Cα=O versus Cα-OH) and in the presence or absence of a hydroxymethyl group

β‐Catenin/c‐Myc Axis Modulates Autophagy Response to Different Ammonia Concentrations

Advanced Biology, Volume 9, Issue 3, March 2025.
Ammonia, detoxified by the liver into urea and glutamine, impacts autophagy differently at varying levels. Low ammonia activates autophagy via c‐Myc and β‐catenin, while high levels suppress it. Using Huh7 cells and Spf‐ash mice, c‐Myc's role in cytoprotective autophagy is revealed, offering insights into hyperammonemia and potential therapeutic ...

Recycling of NiTi Shape Memory Alloys: Fundamental and Technological Aspects of a Vacuum Induction Melting Processing Route

Advanced Engineering Materials, EarlyView.
The present study investigates recycling of NiTi shape memory alloys via vacuum induction melting. An ingot was synthesized from elemental Ni and Ti and subjected to three subsequent remelting cycles. Remelting increases process durations and impurity levels and adversely affects microstructures and functional properties.
