Biochar-Enhanced Three-Dimensional Conductive Network Thick Electrodes for Efficient Lithium Extraction from Salt Lake Brines with High Magnesia-lithium Ratios
In this study, we developed a biochar-based, 3D-conductive network thick electrode (∼20 mg·cm-2) by in-situ deposition of LiFePO4 (LFP) onto watermelon peel biomass (WB). Utilizing Density Functional Theory (DFT) calculations complemented by experimental data, we confirmed that this The thick electrode exhibits outstanding kinetic properties and a high capacity for lithium intercalation in brines, even in environments where the Magnesia-lithium ratios are significantly high. The electrode showed an impressive intercalation capacity of 30.67 mg·g-1 within 10 minutes in a pure lithium solution. It also maintained high in...

Role of the median preoptic nucleus in the development of chronic deoxycorticosterone acetate (DOCA) ‐salt hypertension
AbstractWe have previously reported that the subfornical organ (SFO) does not contribute to the chronic hypertensive response to DOCA-salt in rats, and yet the organum vasculosum of the lamina terminalis (OVLT) plays a significant role in the development of deoxycorticosterone acetate (DOCA)-salt hypertension. Since efferent fibers of the OVLT project to and through the median preoptic nucleus (MnPO), the present study was designed to test the hypothesis that the MnPO is necessary for DOCA-salt hypertension in the rat. Male Sprague-Dawley rats underwent SHAM (MnPOsham;n = 5) or electrolytic lesion of the MnPO (MnPOx;n...

Hydrophobic TaOx Species Overlayer Tuning Light ‐Driven Methane Chlorination with Inorganic Chlorine
Hydrophobic TaOx species overlayer is in situ fabricated on the surface of sodium tantalate to promote the concentration and effective activation of methane on photocatalyst surface in gas-liquid-solid three phase reaction. Without any noble metal assistance, TaOx/NaTaO3 photocatalyst induces the change from nonactivity over NaTaO3 to the efficiently photocatalytic methane chlorination in sodium chloride solution. AbstractHalogenated methane serves as a universal platform molecule for building high-value chemicals. Utilizing sodium chloride solution for photocatalytic methane chlorination presents an environmentally friend...

Unlocking the Power of Magnesium Batteries: Synergistic Effect of InSb ‐C Composites to Achieve Superior Electrochemical Performance
In this study, the InSb-10%C anode is synthesized by a two-step high-energy ball milling process. The InSb-10%C anode exhibits a remarkably high capacity of up to 448 mA h g−1, significantly improved cycle performance (234 mA h g−1 at 100 cycles) and rate performance (168 mA h g−1 at 500 mA g−1). The above-mentioned superior performance of the InSb-10%C anode for RMBs is attributed to the cellular graphitized amorphous carbon composite structure (CGA) which effectively refines the particle size and restricts the volume expansion. Additionally, the reduced surface electron density of InSb combined with the high cond...

Electrostatics introduce a trade ‐off between mesophilic stability and adaptation in halophilic proteins
AbstractExtremophile organisms have adapted to extreme physicochemical conditions. Halophilic organisms, in particular, survive at very high salt concentrations. To achieve this, they have engineered the surface of their proteins to increase the number of short, polar and acidic amino acids, while decreasing large, hydrophobic and basic residues. While these adaptations initially decrease protein stability in the absence of salt, they grant halophilic proteins remarkable stability in environments with extremely high salt concentrations, where non-adapted proteins unfold and aggregate. The molecular mechanisms by which halo...

A salt bridge of the C ‐terminal carboxyl group regulates PHPT1 substrate affinity and catalytic activity
AbstractPHPT1 is a histidine phosphatase that modulates signaling in eukaryotes through its catalytic activity. Here, we present an analysis of the structure and dynamics of PHPT1 through a combination of solution NMR, molecular dynamics, and biochemical experiments. We identify a salt bridge formed between the R78 guanidinium moiety and the C-terminal carboxyl group on Y125 that is critical for ligand binding. Disruption of the salt bridge by appending a glycine residue at the C-terminus (G126) leads to a decrease in catalytic activity and binding affinity for the pseudo substrate, para-nitrophenylphosphate (pNPP), as wel...

Use of dishwashers fails to inactivate foodborne pathogens in home-canned model foods
This study aimed to evaluate the inactivation of Shiga toxin-producing Escherichia coli O157:H7, Salmonella enterica (ser. Typhimurium, Enteritidis, and Infantis) and Listeria monocytogenes during home canning with a household dishwasher. The 450 mL of blended tomato (acidic liquid food) and potato puree (non-acidic solid food) were prepared with 1.5 % salt and 25 mL vinegar as model foods in glass jars (660 mL). The two model foods were sterilized, then inoculated with separate cocktails of each pathogen at 106-107 CFU/g. The prepared jars were placed in the bottom rack of a dishwasher and subjected to the following cycle...
