Direct and Indirect Interfacial Electron Transfer at a Plasmonic p-CuS/CdS Heterojunction.

Plasmonic semiconductors exhibit significant potential for harvesting near-IR solar energy, although their mechanisms of plasmon-induced hot electron transfer (HET) are poorly understood. We report a transient absorption study of plasmon-induced HET in p-CuS/CdS type II heterojunctions. Near-IR excitation of the p-CuS plasmon band at ∼1400 nm leads to ultrafast HET into the CdS conduction band with a time constant of <150 fs and a quantum efficiency of ∼0.

Background: MYB transcription factors (TFs) play crucial roles in the response to diverse abiotic and biotic stress factors in plants. In this study, the GsMYB10 gene encoding a MYB-CC transcription factor was cloned from wild soybean BW69 line. However, there is less report on the aluminum (Al)-tolerant gene in this subfamily.

Mast Cells Contribute to Pressure Overload-Induced Myocardial Hypertrophy by Upregulating TRPV4 via Histamine: Role of Ca2+/ CnA/NFATc3 Signaling Pathway.

Objective: To investigate whether cardiac mast cells (MCs) participate in pressure overload-induced myocardial hypertrophy through the regulation of transient receptor potential vanilloid 4 (TRPV4).

Methods: Pressure overload-induced myocardial hypertrophy was induced via abdominal aortic constriction (AAC). Myocardial hypertrophy was evaluated by measuring the heart weight index (HW/BW), lung weight index (LW/BW), ratio of heart weight to tibia length (HW/TL), ratio of lung weight to tibia length (LW/TL), and cross-sectional area of myocardial cells.

Abnormal eye movements: relationship with clinical symptoms and predictive value for Alzheimer's disease.

However, the characteristics of abnormal eye movements of patients with AD and their relationship with clinical symptoms remain inconsistent, and their predictive value for diagnosing and monitoring the progression of AD remains unclear.

Methods: A total of 42 normal controls, 63 patients with mild cognitive impairment due to AD (AD-MCI), and 49 patients with dementia due to AD (AD-D) were recruited.

Investigating the synergistic effects of nano-zinc and biochar in mitigating aluminum toxicity in soybeans.

Aluminum (Al) toxicity limited root growth by reducing nutrient translocation and promoting reactive oxygen species (ROS) accumulation, particularly in soybean. The endophyte of root could be modified by plant metabolites, which could potentially alter the tolerance to environmental toxicity of plants in acidic-Al soils. To explore how they help soybean mitigate Al toxicity by altering root endophytes, zinc oxide nanoparticles (ZnO NPs) at doses of 0, 30, 60, 90 mg/kg and 2% biochar (BC) were selected as bio modifiers, and Al(SO) at 19 mg/kg was used to simulate Al toxicity.

Molecular catalyst coordinatively bonded to organic semiconductors for selective light-driven CO reduction in water.

The selective photoreduction of CO in aqueous media based on earth-abundant elements only, is today a challenging topic. Here we present the anchoring of discrete molecular catalysts on organic polymeric semiconductors via covalent bonding, generating molecular hybrid materials with well-defined active sites for CO photoreduction, exclusively to CO in purely aqueous media. The molecular catalysts are based on aryl substituted Co phthalocyanines that can be coordinated by dangling pyridyl attached to a polymeric covalent triazine framework that acts as a light absorber.

Oligoyne bridges enable strong through-bond coupling and efficient triplet transfer from CdSe QD trap excitons for photon upconversion.

Polyyne bridges have attracted extensive interest as molecular wires due to their shallow distance dependence during charge transfer. Here, we investigate whether triplet energy transfer from cadmium selenide (CdSe) quantum dots (QDs) to anthracene acceptors benefits from the high conductance associated with polyyne bridges, especially from the potential cumulene character in their excited states. Introducing π-electron rich oligoyne bridges between the surface-bound anthracene-based transmitter ligands, we explore the triplet energy transfer rate between the CdSe QDs and anthracene core.

A contactless in situ EFISH method for measuring electrostatic potential profile of semiconductor/electrolyte junctions.

In photoelectrochemical cells, promising devices for directly converting solar energy into storable chemical fuels, the spatial variation of the electrostatic potential across the semiconductor-electrolyte junction is the key parameter that determines the cell performance. In principle, electric field induced second harmonic generation (EFISH) provides a contactless in situ spectroscopic tool to measure the spatial variation of electrostatic potential. However, the total second harmonic generation (SHG) signal contains the contributions of the EFISH signals of semiconductor space charge layer and the electric double layer, in addition to the SHG signal of the electrode surface.

Doping of Colloidal Nanocrystals for Optimizing Interfacial Charge Transfer: A Double-Edged Sword.

Doping of colloidal nanocrystals offers versatile ways to improve their optoelectronic properties, with potential applications in photocatalysis and photovoltaics. However, the precise role of dopants on the interfacial charge transfer properties of nanocrystals remains poorly understood. Here, we use a Cu-doped InP@ZnSe quantum dot as a model system to investigate the dopant effects on both the intrinsic photophysics and their interfacial charge transfer by combining time-resolved transient absorption and photoluminescent spectroscopic methods.

CDK4/6 inhibitors plus endocrine therapy vs. placebo plus endocrine therapy for HR+/HER2- advanced breast cancer: a phase III RCTs based meta-analysis.

Background: Does incorporating Cyclin-dependent kinase 4/6 (CDK4/6) inhibitors into endocrine therapy (ET) effectively enhance survival outcomes, notably overall survival (OS), among individuals with hormone receptor-positive (HR+), human epidermal growth factor receptor 2-negative (HER2-) advanced breast cancer? This remains a clinical controversy. We compared the antitumor efficacy and adverse effects (AEs) between CDK4/6 inhibitors + ET (CET) and placebo + ET (PET) by conducting a phase III randomized controlled trials (RCTs) based meta-analysis.

Methods: Seven databases were searched to identify eligible studies, comprising Phase III RCTs comparing CET to PET.

Telemedicine has gained popularity due to the increasing use of technology in our lives. However, no studies have explored the demographic factors affecting acceptability, desirability and adherence (ADA) to telemedicine in Singapore. Our study aims to evaluate the level of ADA of telemedicine services within demographic factors and to explore the association of potential demographic factors with the degree of acceptability, desirability and adherence of telemedicine among older adults in Singapore.

Transcriptomic decoding of regional cortical vulnerability to major depressive disorder.

Previous studies in small samples have identified inconsistent cortical abnormalities in major depressive disorder (MDD). Despite genetic influences on MDD and the brain, it is unclear how genetic risk for MDD is translated into spatially patterned cortical vulnerability. Here, we initially examined voxel-wise differences in cortical function and structure using the largest multi-modal MRI data from 1660 MDD patients and 1341 controls.

Metal-organic framework derived crystalline nanocarbon for Fenton-like reaction.

Nanoporous carbons with tailorable nanoscale texture and long-range ordered structure are promising candidates for energy, environmental and catalytic applications, while the current synthetic methods do not allow elaborate control of local structure. Here we report a salt-assisted strategy to obtain crystalline nanocarbon from direct carbonization of metal-organic frameworks (MOFs). The crystalline product maintains a highly ordered two-dimensional (2D) stacking mode and substantially differs from the traditional weakly ordered patterns of nanoporous carbons upon high-temperature pyrolysis.
