Homogenous power distribution along gyrotron collector walls [PDF]

open access: yes
EC RF power sources will play a major role in the future operation of large scale tokamaks (ITER, DEMO). A 1MW/170GHz gyrotron is the standard RF power unit considered for ITER.

The role of collectors in the flotation of partially oxidised copper ores [PDF]

open access: yes, 2004
The effects of xanthates, dithiophosphates, dithiocarbamates and mixtures of these collectors on the froth flotation performance of partially oxidised and oxidised copper sulphide ores were investigated in this study.

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS 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 ...

Experiment on Synchronous Flotation of Lithium-rubidium-cesium in a Lithium Porcelain Clay Mine in Jiangxi Province

open access: yesKuangchan zonghe liyong
The Li2O grade of a lithium porcelain clay mine in Jiangxi Province is 0.46%. The lithium-containing minerals are mainly lithium muscovite, and the gangue minerals are mainly quartz, albite and potassium feldspar.

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions

open access: yesFEBS Letters, EarlyView.
The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.

Thermodynamic Assessment of Reactions in the Sodium-Oxide Fluxed Aluminothermic Reduction of Manganese Ore with Si, Cr, and Cu Collector Metals

open access: yesCrystals
This study investigates the reaction thermodynamics of the sodium oxide-fluxed aluminothermic reduction of pyrolusite-based manganese ore under self-propagating high-temperature synthesis (SHS) conditions, using Si, Cr, and Cu as collector metals.

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

open access: yesFEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Simulation of Dynamic Processes of Gas Flow in Collector Systems

open access: yes, 2015
By using CFD-simulation, plug length simulation of local resistance type plugged tee, which changes the flow direction, using equations of hydrodynamics was carried out. During simulation, velocity of medium in the thread of the collector system in which
