Causes for inefficiency of water jacket heater and its improvement measures

open access: yesYou-qi chuyun, 2020
Considering the low thermal efficiency, high excess air coefficient and low load rate of the in-service water jacketheater of Shengli Oilfield, the relationship of the load rate, excess air coefficient and fouling resistance with the thermalefficiency of

Study on maximum explosion pressure and maximum pressure rise rate of premixed gas explosion in flameproof enclosure

open access: yesMeikuang Anquan, 2023
In order to study the variation law of the maximum explosion pressure and the maximum pressure rise rate of the premixed gas in the flameproof enclosure, three different flameproof enclosures were selected as the test samples, and the explosion was ...

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Flame balls with thermally sensitive intermediate kinetics [PDF]

open access: yes, 2003
Spherical flame balls are studied using a model for the chemical kinetics which involves a non-exothermic autocatalytic reaction, describing the chain-branching generation of a chemical radical and an exothermic completion reaction, the rate of which ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

open access: yesFEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.
