Machine learning (ML) technology provides potential solutions to address these issues.

Ultrashort and Vertically Aligned Channels: Boosted Lithium Selective Extraction via Hybrid Capacitive Deionization.

Hybrid capacitive deionization (HCDI) is energetically and operationally favorable for Li extraction from salt lake brines. The bottlenecks of current LiMnO (LMO)-based electrodes are their limited Li adsorption rate and capacity, caused by disordered electron/ion transport channels and insufficient ion-accessible sites. Inspired by selective ion uptake processes in mangroves, we propose the strategy, fabricating ultrashort, vertically aligned channels for Li transport in the electrode to enhance the Li selective performance of HCDI.

Study on the Correlation between the Microstructure and Physical Properties of ZnCl Aqueous Solution.

This article focuses on the study of the correlation between the microstructure and physical properties of aqueous zinc chloride solutions. Macroscopic physical properties of zinc chloride aqueous solution were determined, and its microstructure was analyzed by Raman spectroscopy, molecular dynamics simulations, and density functional theory (DFT) calculations. The experimental results of macroscopic physical properties show that with the increase of ZnCl concentration, the conductivity of aqueous solution first increases and then decreases, and the viscosity gradually increases.

Primate-Specific DAZ Regulates Translation of Cell Proliferation-Related mRNAs and is Essential for Maintenance of Spermatogonia.

Primate-specific DAZ (deleted in azoospermia) has evolved in the azoospermia factor c (AZFc) locus on the Y chromosome. Loss of DAZ is associated with azoospermia in patients with deletion of the AZFc region (AZFc_del). However, the molecular mechanisms of DAZ in spermatogenesis remain uncertain.

Electronanofiltration Membranes with a Bilayer Charged Structure Enable High Li/Mg Selectivity.

Achieving separation of lithium and magnesium with similar radii is crucial for the current lithium extraction technology from salt lakes, which usually possess a high lithium-to-magnesium ratio. Herein, we proposed the facile sequential interfacial polymerization (SIP) approach to construct electronanofiltration membranes (ENFMs) with a bilayer charged structure consisting of a high positively charged surface and a negatively charged sublayer. The trimesoyl chloride (TMC) concentration was adjusted to enhance the -COOH content and negative charge of the polyamide sublayer to promote Li migration, and then the quaternized polyethylenimine was introduced to the membrane surface by the SIP process to increase the positive charge density on the surface of the ENFMs, which would block the migration of Mg and enhance the Li/Mg selectivity of the ENFMs.

Comparative Investigation of the Microstructure of MgCl Aqueous Solutions Using Different X-ray Scattering Sources, Raman Spectroscopy, and Atomistic Simulations.

Aqueous solutions of magnesium chloride (MgCl(aq)) are often used to test advances in the theory of electrolyte solutions because they are considered an ideal strong 2:1 electrolyte. However, there is evidence that some ion association occurs in these solutions, even at low concentrations. Even a small ion-pairing constant can have a significant impact on the chemical speciation of ions, so it is important to determine whether ion pairing actually occurs.

Selective electrodialysis process for the recovery of potassium from multicomponent solution systems.

Selective electrodialysis is a promising approach to recovering K from complex coexisting ionic systems. In this study, the effects of current density, the concentration of K and Mg, as well as the operating temperature on the separation process of K and Mg were explored to investigate the competitive migration of mono- and multivalent ions, offering a guide for the design of selective electrodialysis process, and therefore obtain the desired aqueous solutions containing K and Mg. The results show that ion concentration played a critical role in determining the selectivity of separation between K and Mg.

Identification of a missense variant of MND1 in meiotic arrest and non-obstructive azoospermia.

Meiotic arrest is a common pathologic phenotype of non-obstructive azoospermia (NOA), yet its genetic causes require further investigation. Meiotic nuclear divisions 1 (MND1) has been proved to be indispensable for meiotic recombination in many species. To date, only one variant of MND1 has been reported associated with primary ovarian insufficiency (POI), yet there has been no report of variants in MND1 associated with NOA.
