In Situ Constructing of Rigid-Soft Coupling Solid-Electrolyte Interphase on Silicon Electrode toward High-Performance Lithium Ion Batteries.

The application of Si anodes is hindered by some critical issues such as large volume changes of bare Si and fragile solid-electrolyte interface (SEI), resulting in low coulombic efficiency and rapid capacity decay. Herein, a multifunctional SEI film with high content of LiF is in situ constructed via the surface grafting of carbon-fluorine functionalized groups on silicon nanoparticles (SiNPs) during cycling. Mechanical study demonstrates that the incorporation of LiF with high modulus and unbroken carbon-fluorine groups with highly elastic guarantee the rigid-soft coupling SEI film on Si electrode.

Recovery of valuable metals from spent lithium-ion batteries by complexation-assisted ammonia leaching from reductive roasting residue.

Recycling valuable metals in spent LIBs is not only in line with the purpose of resource recycling but also an important measure for environmental protection. In this article, a process using biomass reduction roasting followed by a unique complexation-assisted ammonia leaching is proposed. Using waste areca powder (WAP) as a biomass reducing agent, the roasted residue is leached in an aqueous solution for the carbonate.

One-step selective separation and efficient recovery of valuable metals from mixed spent lithium batteries in the phosphoric acid system.

The recovery of valuable elements in spent lithium-ion batteries (LIBs) has attracted more and more attention. Efficient recovery of valuable elements from spent LIBs with lower consumption and shorter process is the target that people have been pursuing. In this study, the valuable metals (Ni, Co, Mn and Li) and FePO products are simultaneously recovered from mixed spent LiNiCoMnO and LiFePO in one step under the optimized condition of 0.

Altered expression levels of IDH2 are involved in the development of colon cancer.

IDH2 encodes a mitochondrial metabolic enzyme that converts isocitrate to α-ketoglutarate (α-KG) by reducing nicotinamide adenine dinucleotide phosphate (NADP(+)) to NADPH and participates in the citric acid cycle for energy production. Notably, this gene has been shown to be critical for cell proliferation. The abnormal expression of IDH2 has been reported in several types of cancer, and mutations in IDH2 have been identified in gliomas and acute myelogenous leukemia.

[Inhibitory effect of N-acetylcysteine upon atherosclerotic processes in rabbit carotid].

Objective: To discuss the effect of N-acetylcysteine (NAC) upon matrix metalloproteinases (MMP) in the atherosclerotic processes in rabbit carotid.

Methods: The atherosclerotic models were generated in vitro by injuring rabbit internal carotid with arterial canal balloon. These rabbits were divided into 3 groups (15 mg/kg NAC, 30 mg/kg NAC and control group) and treated for 8 weeks.

[Effects of probucol, aspirin and atorvastatin combination therapy upon atherosclerosis].

Objective: To investigate the effects of probucol, aspirin and atorvastatin (PAS) combination therapy upon atherosclerosis.

Methods: A total of 436 patients with coronary artery disease were selected and randomly divided into control group (aspirin 100 mg, atorvastatin 10 mg daily) and PAS group (aspirin 100 mg, atorvastatin 10 mg and probucol 0.25 g daily).
