Simulation Study for the Adsorption of Carbon Disulfide on Hydroxyl Modified Activated Carbon

Molecules, 2023
In this study, grand canonical Monte Carlo simulations (GCMC) and molecular dynamics simulations (MD) were used to construct models of activated carbon with hydroxyl-modified hexachlorobenzene basic unit contents of 0%, 12.5%, 25%, 35% and 50%.

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

FEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Effect of competitive adsorbents on the distribution of active components and mercury adsorption performances of brominated activated carbon

矿业科学学报, 2018
In order to explore the effect of competitive adsorbents on the distribution of mercury removal active components of activated carbon and its mercury adsorption performances, a kind of commercial activated carbon was pretreatmented by acetic acid and ...

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

One-step thermochemical activation of waste wood for micropollutant adsorption: Optimisation via design of experiments

Case Studies in Chemical and Environmental Engineering
The increasing generation of waste wood (WW) and the demand for activated carbon (AC) in wastewater treatment highlight the need for sustainable alternatives. WW was converted into AC via one-step thermochemical activation using carbon dioxide, steam, or

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Controlling sub-nanometer pore-entrance size enables kinetic separation of Li+, Na+, and K+ in capacitive deionization

Carbon Trends
Efficient recovery of lithium and potassium from saline resources is vital for energy storage and global food security. We present a novel capacitive deionization (CDI) approach employing carbon molecular sieve (CMS) electrodes with precisely tuned sub ...

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

FEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Comparative study on filtration effect of powdered activated carbon and activated carbon fiberboard on strong-flavor Baijiu [PDF]

Zhongguo niangzao
In this study, the filtration performance of activated carbon fiberboard (AKS1, AKS2, AKS4, R11, R33, R54) and powdered activated carbon on the filtration effect of 48%vol strong-flavor (Nongxiangxing) Baijiu was systematically compared.

Cytoplasmic p21 promotes stemness of colon cancer cells via activation of the NFκB pathway

Molecular Oncology, EarlyView.
Cytoplasmic p21 promotes colorectal cancer stem cell (CSC) features by destabilizing the NFκB–IκB complex, activating NFκB signaling, and upregulating BCL‐xL and COX2. In contrast to nuclear p21, cytoplasmic p21 enhances spheroid formation and stemness transcription factor CD133.
