Study on removal of oxide from carrier salt in molten salt reactor by vacuum distillation

open access: yesHe jishu, 2022
BackgroundIn molten salt reactor, the concentration of oxygen impurities in the molten salt should be strictly controlled to avoid the potential safety risks caused by the reaction of O2- in the carrier salt with UF4 fuel to generated UO2 precipitation ...

Transcripts enriched in codons that trigger P‐site tRNA‐mediated mRNA decay possess stable mRNA

open access: yesFEBS Open Bio, EarlyView.
PTMD codons were first described by Mendel et al. as mediators of an mRNA decay pathway dependent on the human protein CNOT3, homologous to yeast Not5. Our findings confirm that PTMD codons destabilize transcripts; however, unlike in yeast, the human pathway specifically targets and slightly destabilizes primarily stable mRNAs.

APPLICATIONS OF MOLECULAR DISTILLATION TECHNIQUE IN FOOD PRODUCTS

open access: yesItalian Journal of Food Science, 2015
There are several separation techniques -including conventional distillation- for extracting heat sensitive compounds from food products. However, some compounds may have high boiling points at which other compounds might be adversely affected.

Separation of Iron(II) and Vanadium(IV)、Chromium(III) from Low Valence Vanadium Solution and Preparation of Mohr's Salt

open access: yesKuangchan zonghe liyong, 2022
In this study, the leaching solution containing vanadium(IV), chromium(III) and iron(II) obtained in the process of extracting low valence vanadium from vanadium slag was taken as the research object, and the vacuum cooling method was applied to ...

Dose‐dependent hepatotoxicity of hydrogen peroxide in HepG2 cells and its modulation by CYP450 induction

open access: yesFEBS Open Bio, EarlyView.
NMR metabolomics revealed concentration‐dependent metabolic perturbations in HepG2 cells exposed to H2O2. Rifampicin pretreatment enhanced metabolic competence, attenuated toxin‐induced alterations and produced metabolite profiles more consistent with human liver physiology, supporting the use of CYP450‐induced HepG2 models for improved in vitro ...

The concept of vacuum in quantum electrodynamics [PDF]

open access: yes, 2010
A re-evaluation of the concept of vacuum in quantum electrodynamics is presented, focusing on the vacuum of the quantized electromagnetic field. In contrast to the ‘nothingness’ associated to the idea of classical vacuum, subtle aspects are found in ...

Nanocrystalline Ag-ZK-5 zeolite for selective CH4/N2 separation

open access: yes, 2022
Decreasing crystal size and introducing more electronegative extraframework metal cations to small-pore zeolites provide clear-cut advantages for small gas adsorption and separations. Here, nanocrystalline (similar to 100 nm) silver-exchanged ZK-5 (Ag-ZK-

Structural studies and functional engineering of NanX: an anhydro‐sialic acid transporter from Escherichia coli

open access: yesFEBS Open Bio, EarlyView.
Biophysical characterisation shows that NanX, a membrane transport protein from the major facilitator superfamily (MFS), forms both monomers and dimers after purification. AlphaFold modelling and substrate docking provide information on residues likely involved in substrate recognition for NanX and another MFS member, NanT.

Separation and Enrichment of Au and Ag from Lead Anode Slime by a Selective Oxidation–Vacuum Volatilization–Carbon Reduction Process

open access: yesMetals
Huge amounts of Au and Ag are recovered from the hazardous waste lead anode slime. The conventional extraction of precious metals from lead anode slime is based on pyrometallurgical and electrolytic processes, which are seriously conditioned by the ...

Clogging mechanism and effect of cake permeability in soil-water separation using vacuum filtration

open access: yesYantu gongcheng xuebao, 2017
The cutter suction dredger is often used in dredging of rivers and lakes. The core of this method of dredging is to extract the mixture of sediment and water after the agitating process.
