All-Optical Modulation Photodetectors Based on the CdS/Graphene/Ge Sandwich Structures for Integrated Sensing-Computing.

In this manuscript, an all-optical modulation photodetector based on a CdS/graphene/Ge sandwich structure is designed. In the presence of the modulation (near-infrared) light, the Fermi level of the graphene channel shifts, allowing for the tuning of the visible light response speed as well as achieving a broad responsivity range from negative (-3376 A/W) to positive (3584 A/W) response. Based on this, logical operations are performed by adjusting the power of the modulation light superimposed with the signal light.

Synthesis and characterization of heterotrimetallic Mg-Ni-Mg complexes with amidinato ligands.

Treatment of amidinato-based magnesium ethyl compounds LMgEt [L = PrPNC(Bu)NAr; Ar = 2,6-PrCH (La) or 2,6-(PhCH)-4-Pr-(CH) (Lb)] with Ni(COD) (COD: 1,5-cyclooctadiene) afforded heterotrimetallic Mg-Ni-Mg complexes [(LMg)Ni(CH)] through β-H elimination. These complexes exhibit approximately linear Mg-Ni-Mg linkage with the central nickel arranged in a planar configuration; the Ni(CH) unit can be considered as nickela-bis-cyclopropane. Reaction of [(LMg)Ni(CH)] with tetrahydrofuran (THF) gave a coordination product [(LMg·THF)Ni(CH)], in which the central structure remained intact and THF coordinated to two magnesium atoms respectively.

Emamectin Benzoate and Microplastics Led to Skeletal Muscle Atrophy in Common Carp via Induced Oxidative Stress, Mitochondrial Dysfunction, and Protein Synthesis and Degradation Imbalance.

Pesticides and plastics have brought convenience to agricultural production and daily life, but they have also led to environmental pollution through residual chemicals. Emamectin benzoate (EMB) is among the most widely used insecticides, which can cause environmental pollution and harm the health of organisms. Additionally, microplastics (MPs), a relatively new type of pollutant, not only are increasing in residual amounts within water bodies and aquatic organisms but also exacerbate pollution by adsorbing other pollutants, leading to a mixed pollution scenario.

NHC-Based Deep-Red Phosphorescent Iridium Complexes Featuring Three-Charge (0, -1, -2) Ligands.

N-heterocyclic carbene (NHC)-based phosphorescent iridium complexes have attracted extensive attention due to their good optical properties and high stability in recent years. However, currently reported NHC-based iridium complexes can easily achieve emission of blue, green, or even ultraviolet light, while emission of red or deep-red light is relatively rare. Here, we report a new family of NHC-based deep-red iridium complexes (Ir1, Ir2, Ir3, and Ir4) featuring three-charge (0, -1, -2) ligands.

Fe-Catalyzed Hydrocyclization of Inactivated Alkenes to Synthesize Ring-Fused 2,3-Dihydroquinazolinone.

A Fe-catalyzed hydrocyclization reaction of unactivated alkenes was developed, utilizing PhSiH as the hydrogen source, yielding 2,3-dihydroquinazolinone (DHQZ) derivatives in moderate to good yields. Notably, when the substrate was switched to -cyano--(2-(prop-1-en-2-yl)phenyl)benzamides, the reaction yielded only the unreduced products. Mechanistic studies revealed that the intramolecular addition of the in situ formed radical to the unactivated alkene results in the formation of the fused ring.

Improved Efficacy of Triple-Negative Breast Cancer Immunotherapy via Hydrogel-Based Co-Delivery of CAR-T Cells and Mitophagy Agonist.

Leaky and structurally abnormal blood vessels and increased pressure in the tumor interstitium reduce the infiltration of CAR-T cells in solid tumors, including triple-negative breast cancer (TNBC). Furthermore, high burden of tumor cells may cause reduction of infiltrating CAR-T cells and their functional exhaustion. In this study, various effector-to-target (E:T) ratio experiments are established to model the treatment using CAR-T cells in leukemia (high E:T ratio) and solid tumor (low E:T ratio).

ZnFe Layered Double Hydroxide Nanosheets Loaded with Cu Single-Atom Nanozymes with Multi-Enzyme-Like Catalytic Activities as an Effective Treatment for Bacterial Keratitis.

Bacterial keratitis (BK) is a type of corneal inflammation resulting from bacterial infection in the eye. Although nanozymes have been explored as promising materials in corneal wound healing, currently available nanozymes lack sufficient catalytic activity and the ability to penetrate bacterial biofilms, limiting their efficacy against the treatment of BK. To remedy this, ZnFe layered double hydroxide (ZnFe-LDH) nanosheets are loaded with Cu single-atom nanozymes (Cu-SAzymes) and aminated dextran (Dex-NH), resulting in the formation of the nanozyme DT-ZnFe-LDH@Cu, which possesses peroxidase (POD)-, oxidase (OXD)-, and catalase (CAT)-like catalytic activities.
