Bimetallic sulfides based hybrid anodes are constructed for high-performance lithium ion batteries.

Transition metal sulfides (TMSs) are considered as one of the most promising anode materials for lithium-ion batteries (LIBs) in virtue of their high theoretical specific capacity, low cost and environmental friendliness. However, the intrinsic poor electron/ion transport, large volume change and the shuttle effect of polysulfides hinder their achievement of superb rate capability and cycle performance. Compared with the monometallic sulfides, bimetallic sulfides have superior electron transport capability and higher electrochemical activity.

A single nucleotide polymorphism affects protein translation and leads to post-anthesis color change variation in closely related Lotus species.

Flower color change, a common phenomenon that is important in pollination ecology, has intrigued scientists for decades. While previous flower color studies have mainly focused on color diversity among different plant species, our focus is on unraveling the mechanism of post-anthesis color change (PACC) and the molecular basis for its presence and absence, respectively, in two closely related species of Lotus, Lotus filicaulis and Lotus japonicus MG20. Metabolomic analysis reveals anthocyanins as the key metabolites responsible for the observed PACC.

Efficient construction of high-quality sulfonated porous aromatic frameworks by optimizing the swelling state of porous structures.

Conventional post-modification methods usually face the fundamental challenge of balancing the high content of functional groups and large surface area for porous organic polymers (POPs). The reason, presumably, stems from ineffective and insufficient swelling of the porous structure of POP materials, which is detrimental to mass transfer and modification of functional groups, especially with large-sized ones. It is important to note that significant differences exist in the porous structures of POP materials in a solvent-free state after thermal activation and solvent swelling state.

AlBC with High Ambipolar Mobility Driven by a Unique B-C Framework.

The development of materials with high ambipolar mobility is pivotal for advancing multifunctional applications, yet such materials remain scarce. Presently, cubic boron arsenide (BAs) stands out as the premier ambipolar material, demonstrating an ambipolar mobility of ∼1600 cm V s at room temperature [ 2022, 377, 433 and 2022, 377, 437]. Herein, we illustrate that semiconducting AlBC, featuring a nonclathrate B-C framework in which a C atom bonds to the vertices of four distorted hexagonal antiprism B units via quasi-sp hybridization, is predicted to possess ambipolar carrier transport behavior.

Review of the Bioactivities and Mechanisms of Fungus Extracts and Compounds in Colon Cancer.

Colon cancer, a malignant tumor caused by a malignant lesion of the colonic mucosal epithelium, has seen a high incidence in recent years. Fungi contain polysaccharides, terpenes, flavonoids, and other chemical components, and the diversity of these components determines the strength of a fungus's biological activity. Studies have shown that the chemical components in fungi can be used as drugs to inhibit the growth of colon cancer.

Dual Photoredox/Copper-Catalyzed Three-Component Alkylcyanation of Alkenes and 1,4-Alkylcyanation of 1,3-Enynes Employing Sulfoxonium Ylides as the Carbon Radical Precursors.

A novel dual photoredox/copper-catalyzed three-component alkylcyanation of alkenes and 1,4-alkylcyanation of 1,3-enynes have been developed. In this radical cyanoalkylation reaction, the photoredox induced alkyl radical from sulfoxonium ylides adds to the carbon-carbon double bonds of styrenes or 1,3-enynes, and the generated benzylic or allenyl radicals couple with a Cu(II) cyanide complex to achieve selective cyanation. The reaction exhibits high chemo- and regioselectivity and a wide substrate scope, providing an efficient method for the synthesis of alkyl nitriles and allenyl nitriles in a single step.

Constructing a Metal-Organic Frameworks-Based Long-Acting Sequential Release System for the Treatment of Alzheimer's Disease.

Due to the unclear pathogenesis of Alzheimer's disease (AD) and the lack of a completely cured medication, AD patients need to take medication in order and on time every day all one's life, which is difficult for severe memory impairment patients to strictly follow on time. Traditional AD drug carriers, such as sugar coating and capsules, rely on dissolution or fragmentation to achieve drug release, which lacks the interaction between drug molecules and carriers, thus they cannot achieve sufficient long-acting and sequential drug release. Herein, Mn-MOF-74, which ligand structure is similar to two antioxidants dihydroquercetin (DHQ) and resveratrol (Res) is chosen as the carrier.
