Optimizing Photovoltaic Performance through Functional End-Capping Units of Polymer Donor Materials.

Advancing the photovoltaic performances of organic solar cells (OSCs) is vital for commercialization. High-performance OSC active layers commonly comprise polymer donors and small molecule acceptors. Enhanced crystallinity, ordered molecular packing, and strong intermolecular interactions in polymer donors can improve carrier mobility and photovoltaic performance.

Fabricating High-Performance Organic Solar Cells by Using Inside-Chain Chlorinated Acceptor as a Ternary Component.

In this study, two molecules, WLA1 and WLA2, with the same molecular backbone but with different degrees of inside-chain chlorination, are designed and synthesized to elucidate the effects of chlorine substitution strategies on the morphology of small-molecule acceptors and blended films. The chlorinated WLA2 enhances crystallinity and molecular stacking. For binary organic solar cells (OSCs), the corresponding blended films of WLA2 exhibit suitable phase separation and crystallinity.

Constructing efficient organic solar cells by highly volatile solid additives with controlled phase morphology.

We synthesized two highly volatile and low-cost solid additives, PT and TFT. The inclusion of PT and TFT effectively influences the aggregation behavior of D18: L8-BO during the film-forming process. Consequently, PT and TFT-treated D18: L8-BO-based OSCs achieved power conversion efficiencies of 18.

The finite element analysis study of the impact of single and double lag screw fixation on ankle fractures of different sizes.

In clinical practice, the choice of single double screw fixation for posterior malleolus fractures (PMF) is theoretically unclear, particularly concerning the size-stability relationship. This study, employing Finite Element Analysis (FEA), assesses biomechanical stability in PMF of varying sizes under both fixation methods. Utilizing a 3D model based on CT scans, we simulated fractures with 10-50% fragment sizes and applied a 600 N force to mimic the single-leg stance.

Employing Bayesian analysis to establish a cut-off point and assess stigma prevalence in substance use disorder: a comprehensive study of the Chinese version of the Substance Use Stigma Mechanism Scale.

Purpose: In China, individuals with substance use disorders (SUD) face severe stigma, but reliable stigma assessment tool is lacking. Therefore, this study aimed to validate the Chinese version of the Substance Use Stigma Mechanism Scale (SU-SMS-C) and set its cut-off point.

Methods: We recruited 1005 individuals with SUDs from Chinese rehabilitation centers.

The Mediating Effects of Perceived Family Support in the Relationship Between Anxiety and Problematic Smartphone Use: A Cross-Cultural Validation.

Problematic smartphone use (PSU) is frequently considered a public health issue, especially in East Asia and Europe. Yet, there is a paucity of research focusing on cultural and familial determinants of PSU. This cross-cultural study aimed to investigate smartphone usage patterns and possible mediating effects of perceived family support (PFS) from a stress-coping perspective.

Gender differences in alcohol abuse/dependence among medical undergraduates during the post-COVID‑19 pandemic period (October 20, 2020-April 5, 2021) in China.

Background: This study aimed to assess the prevalence and the gender-specific risk factors of alcohol abuse/dependence among medical undergraduates during the post-COVID‑19 pandemic period in China.

Method: The Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) was used to identify respondents with alcohol abuse/dependence. A questionnaire on basic demographics and mental distresses (learning burnout, depression symptoms, anxiety symptoms, excessive daytime sleepiness, and history of mental disorders) was used.

Effects of Multiple High-Dose Methamphetamine Administration on Enteric Dopaminergic Neurons and Intestinal Motility in the Rat Model.

Several studies have identified the effects of methamphetamine (MA) on central dopaminergic neurons, but its effects on enteric dopaminergic neurons (EDNs) are unclear. The aim of this study was to investigate the effects of MA on EDNs and intestinal motility. Male Sprague-Dawley rats were randomly divided into MA group and saline group.
