Low-Frequency Phonon Dispersion Relation Enabling Stable Cathode from Spent Lithium-Ion Batteries.

Direct recycling technology can effectively solve the environmental pollution and resource waste problems caused by spent lithium-ion batteries. However, the repaired LiNiCoMnO (NCM) black mass by direct recycling technology shows an unsatisfactory cycle life, which is attributed to the formation of spinel/rock salt phases and rotational stacking faults caused by the in-plane and out-of-plane migration of transition metal (TM) atoms during charge/discharge. Herein, local lattice stress is introduced into the regenerated cathode during repair.

Regulating Strain and Suppressing Defect States Through Polymer Ionization and Chemical Chelation for Efficient Inverted Flexible Perovskite Solar Cells.

Flexible perovskite solar cells (FPSCs) have great promise for applications in wearable technology and space photovoltaics. However, the unpredictable crystallization of perovskite on flexible substrates results in significantly lower efficiency and mechanical durability than industry standards. A strategy is investigated employing the polymer electrolyte poly(allylamine hydrochloride) (PAH) to regulate crystallization and passivate defect states in perovskite films on flexible substrates.

Exploring the relationship between air pollution, non-alcoholic fatty liver disease, and liver function indicators: a two-sample Mendelian randomization analysis study.

Background And Aims: Non-alcoholic fatty liver disease (NAFLD) is a common metabolic disorder worldwide, with an increasing incidence in recent years. While previous studies have suggested an association between the air pollutant PM2.5 and NAFLD, there is still considerable debate regarding the existence of a clear causal relationship between air pollution and NAFLD.

Durable and Damageless Supramolecular Binder for Fast, Stable, and Sustainable Si-Based Anodes.

Mechanical fatigue of the binders during the repeated volume change of Si-based anodes induces binder network collapse, resulting in lithium-ion batteries (LIBs) failing prematurely. Herein, we designed a damageless polymer binder with a mechanically interlocked network utilizing [n]daisy chains (MIN) and poly(acrylic acid) (PAA) to improve the structural cohesion of the Si-based anode. This MIN@PAA binder exhibits robust mechanical properties, high elasticity, and excellent adhesion.

Interface Degradation of LaCl-Based Solid Electrolytes Coupled with Ultrahigh-Nickel Cathodes.

Despite competitive compatibility with high-nickel cathodes, chloride solid electrolytes (SEs) still experience inevitable side reactions at the cathode/SE interface, causing capacity decay in all-solid-state lithium batteries (ASSLBs) during cycling. Herein, a three-electrode ASSLB testing device is developed to comprehensively reveal the interface failure mechanisms of the ultrahigh-nickel LiNiCoMnO (NCM92) cathode paired with LaCl-based chloride SE LiLaZrTaCl (LLZTC). Distribution of relaxation time (DRT) analysis clearly shows the ASSLB degradation accompanied by a significant NCM92/LLZTC interface impedance increase, which becomes more pronounced at the higher cutoff charging voltage of 4.

Generative learning assisted state-of-health estimation for sustainable battery recycling with random retirement conditions.

Rapid and accurate state of health (SOH) estimation of retired batteries is a crucial pretreatment for reuse and recycling. However, data-driven methods require exhaustive data curation under random SOH and state of charge (SOC) retirement conditions. Here, we show that the generative learning-assisted SOH estimation is promising in alleviating data scarcity and heterogeneity challenges, validated through a pulse injection dataset of 2700 retired lithium-ion battery samples, covering 3 cathode material types, 3 physical formats, 4 capacity designs, and 4 historical usages with 10 SOC levels.

Metagenomic study of the microbiome and key geochemical potentials associated with architectural heritage sites: a case study of the Song Dynasty city wall in Shou County, China.

Historical cultural heritage sites are valuable for all of mankind, as they reflect the material and spiritual wealth of by nations, countries, or specific groups during the development of human civilization. The types and functions of microorganisms that form biofilms on the surfaces of architectural heritage sites influence measures to preserve and protect these sites. These microorganisms contribute to the biocorrosion of architectural heritage structures through the cycling of chemical elements.

Cell-Inspired Microreactor with Compartmentalized Active Sites for Development of Cascade Catalysis System in Biosensing.

Enzymatic cascade reactions with high activity and specificity in living cells always benefit from multicompartmentalized organelles that provide separately confined spaces for enzymes, avoiding their mutual interference to ensure the high-efficiency operation of necessary vital movements. Inspired by this, we designed a 3D spherical microreactor (Au@H-APF@Pt) with biomimetic cascade catalysis for glucose detection. First, ultrasmall gold nanoparticles were immobilized in situ on the internal cavities of hollow 3-aminophenol formaldehyde resin (H-APF) nanospheres, along with glucose oxidase activity.

Association between dietary intake of iron and heart failure among American adults: data from NHANES 2009-2018.

Patients with heart failure (HF) often experience iron deficiency. Intravenous iron supplementation has been widely used in clinical practice to facilitate the treatment of HF. However, the association between dietary iron intake and HF still needs to be elucidated.

Sulforaphane Attenuates Ethanol-Induced Teratogenesis and Dysangiogenesis in Zebrafish Embryos.

Prenatal ethanol exposure can cause a broad range of abnormalities in newborns known as Fetal Alcohol Spectrum Disorder (FASD). Despite significant progress in understanding the disease mechanisms of FASD, there remains a strong global need for effective therapies. To evaluate the therapeutic potential of sulforaphane (SFN), an active compound extracted from cruciferous vegetables, in preventing FASD, ethanol-exposed zebrafish embryos were pretreated, co-treated, or post-treated with various concentrations of SFN.

The AMPK-mTOR Pathway Is Inhibited by Chaihu Shugan Powder, Which Relieves Nonalcoholic Steatohepatitis by Suppressing Autophagic Ferroptosis.

Nonalcoholic steatohepatitis (NASH) is the advanced stage of nonalcoholic fatty liver disease (NAFLD), which is distinguished by the accumulation of fat in the liver, damage to liver cells, and inflammation. Chaihu Shugan powder (CSP), a renowned traditional Chinese medicine (TCM) blend extensively utilized in China to address liver disease, has demonstrated its efficacy in reducing lipid buildup and effectively combating inflammation. Hence, the primary objective of this research is to examine the impacts and possible mechanisms of CSP on NASH through assessments of liver histopathology, lipidomic analysis, and gene expression.
