Dong Wang
Using silicon/reduced graphene oxide (Si/rGO) composites as lithium-ion battery (LIB) anodes can effectively buffer the volumetric expansion and shrinkage of Si. Herein, we designed and prepared Si/rGO-b with a sandwiched structure, formed by a duple combination of ammonia-modified silicon (m-Si) nanoparticles (NP) with graphene oxide (GO). In the first composite process of m-Si and GO, a core–shell structure of primal Si/rGO-b (p-Si/rGO-b) was formed. The amino groups on the m-Si surface can not only hybridize with the GO surface to fix the Si particles, but also form covalent chemical bond...

High ‐Branched Natural Polysaccharide Flaxseed Gum Binder for Silicon‐Based Lithium‐Ion Batteries with High Capacity
FG is used as a silicon-based anode binder for lithium-ion batteries for the first time. As FG possesses abundant polar groups and branched chains, it enhances the mechanical properties of the silicon electrode and greatly improves the cycling stability of the silicon electrode. AbstractSilicon-based anodes heavily depend on the binder to preserve the unbroken electrode structure. In the present work, natural flaxseed gum (FG) is used as a binder of silicon nanoparticles (SiNPs) anode for the first time. Owing to a large number of polar groups and a rich branched structure, this material not only anchors tightly to the sur...

Angew Chem Int Ed Engl. 2024 May 6:e202402625. doi: 10.1002/anie.202402625. Online ahead of print.ABSTRACTThe interfacial instability of high-nickel layered oxides severely plagues practical application of high-energy quasi-solid-state lithium metal batteries (LMBs). Herein, a uniform and highly oxidation-resistant polymer layer within inner Helmholtz plane is engineered by in-situ polymerizing 1-vinyl-3-ethylimidazolium (VEIM) cations preferentially adsorbed on LiNi0.83Co0.11Mn0.06O2 (NCM83) surface, inducing formation of anion-derived cathode-electrolyte interphase with fast interfacial kinetics.

Tuning Ion Mobility in Lithium Argyrodite Solid Electrolytes via Entropy Engineering
We present, to the best of our knowledge, the first experimental evidence of a direct correlation between occupational disorder in the cationic host lattice and lithium transport. By controlling the configurational entropy through the composition, high bulk ionic conductivities up to 18 mS cm-1 at room temperature were achieved for optimized lithium argyrodite compositions. Our results indicate the possibility of improving ionic conductivity in ceramic ion conductors via entropy engineering, unlocking the compositional limitations for the design of advanced electrolytes and opening up new avenues in the field.PMID:38709977...

PRMT5-mediated arginine methylation of FXR1 is essential for RNA binding in cancer cells
Nucleic Acids Res. 2024 May 6:gkae319. doi: 10.1093/nar/gkae319. Online ahead of print.ABSTRACTEmerging evidence indicates that arginine methylation promotes the stability of arginine-glycine-rich (RGG) motif-containing RNA-binding proteins (RBPs) and regulates gene expression. Here, we report that post-translational modification of FXR1 enhances the binding with mRNAs and is involved in cancer cell growth and proliferation. Independent point mutations in arginine residues of FXR1's nuclear export signal (R386 and R388) and RGG (R453, R455 and R459) domains prevent it from binding to RNAs that form G-quadruplex (G4) RNA st...

Impact of Lithium on the Immune System: An Investigation of T-Cell Subpopulations and Cytokine Responses in Rats
In conclusion, lithium adversely impacted the cellular defense system. Furthermore, apart from its anti-inflammatory properties, lithium exhibited cytokine-mediated inflammatory activities. Therefore, lithium's potential adverse effects on the immune system should be considered in immunodeficient patients and those with an inflammatory status treated with high doses of lithium.PMID:38700635 | DOI:10.1007/s12011-024-04202-8 (Source: Cell Research)

Mineralization of SF < sub > 6 < /sub > and NF < sub > 3 < /sub > fluorinated compounds for greenhouse gas abatement by oxalates
This study investigates the mineralization and removal of two potent FCs: SF6 and NF3. The results confirm that utilizing various oxalate salts leads to the formation of corresponding metallic fluorides: lithium fluoride (LiF), sodium fluoride (NaF), and potassium fluoride (KF), validating the occurrence of mineralization reactions. Among the oxalate salts, sodium oxalate demonstrates the highest mineralization efficiency in both SF6 and NF3 removal. Real-time Fourier transform infrared spectroscopy (FT-IR) gas-phase analysis confirms rapid and complete gas removal within a short reaction time using the selected oxalate sa...
