Heterologous expression and site-directed mutagenesis of soluble methane monoxygenase [PDF]

open access: yes
The purpose of this investigation was to study the heterologous expression of soluble methane monooxygenase (sMMO) genes from Methylococcus capsulatus (Bath) and Methylosinus trichosporium OB3b.

Does Participating in Agricultural Global Value Chains Promote Agricultural Growth?

open access: yesAgribusiness, EarlyView.
ABSTRACT This study examines the relationship between GVC participation and agricultural value‐added growth in 43 countries over the period 1995–2022. In contrast to prior literature, we disaggregate the agricultural sector into four sub‐sectors namely crop cultivation, animal production, forestry and fishing.

Challenges and enablers in fluidization technology

open access: yesAIChE Journal, EarlyView.
Abstract Gas–solid fluidized beds provide excellent heat and mass transfer for high‐throughput operations from coating to catalytic conversion and underpin emerging low‐carbon technologies. Yet industrial reliability, scale‐up, and control lag scientific understanding, particularly as finer, stickier, and more variable feedstocks increasingly challenge

Methane emission rate studies in a central Pennsylvania mine [PDF]

open access: yes
"A methane emission rate study was conducted in 1969 on a longwall section of a Lower Kittanning coalbed mine in central Pennsylvania . The longwall face was mined with a drum shearer between developed headings on the head end and headings on the tail ...

Gas–liquid mass transfer enhancement in the presence of nanoparticles under slug flow in microreactors

open access: yesAIChE Journal, EarlyView.
Abstract Nanofluids containing nanoparticles represent a promising solvent or reaction system for gas–liquid operations. Herein, the effect of nanoparticle (Al2O3 and SiO2) addition on gas–liquid slug flow pattern and mass transfer enhancement was investigated during CO2 absorption into water in microreactors.

Hole‐Activated Lattice Oxygen Enables Pt‐Free Propane Dehydrogenation by Eliminating the Hydrogen Recombination Bottleneck

open access: yesAngewandte Chemie, EarlyView.
Trace Mg doping into gallia–alumina generates hole‐type oxygen species that accelerate hydrogen recombination, eliminating the need for Pt promotion. The fully oxide‐based catalyst resists sintering under repeated regeneration, outperforming benchmark PtSn and CrOx catalysts with exceptional stability over 30 dehydrogenation–regeneration cycles ...

The particulate methane monooxygenase from Methylococcus capsulatus (Bath) [PDF]

open access: yes
The isolation procedure for the pMMO complex has been optimised to obtain a high specific activity enzyme from Methylococcus capsulatus (Bath). The enzyme is comprised of the pMMO hydroxylase (pMMOH) consisting of polypeptides 47,26 and 23kDa ...
