Bithiophene Imide-Based Self-Assembled Monolayers (SAMs) on NiOx for High-Performance Tin Perovskite Solar Cells Fabricated Using a Two-Step Approach.

Three new bithiophene imide (BTI)-based organic small molecules, (), (), and (), with varied alkyl side chains, were developed and employed as self-assembled monolayers (SAMs) applied to NiOx films in tin perovskite solar cells (TPSCs). The NiOx layer has the effect of modifying the hydrophilicity and the surface roughness of ITO for SAM to uniformly deposit on it. The side chains of the SAM molecules play a vital role in the formation of a high-quality perovskite layer in TPSCs.

Navigating recovery in childhood OCD: a qualitative analysis of barriers and facilitators.

Objective: The objective is to examine barriers and facilitators to recovery in children and adolescents with obsessive-compulsive disorder (OCD) using a qualitative approach.

Methods: Ten semi-structured interviews were conducted, audio-recorded, and analyzed using thematic analysis. Findings were validated through investigator triangulation, peer validation and member check.

Measuring Integrin Force Loading Rates Using a Two-Step DNA Tension Sensor.

Cells apply forces to extracellular matrix (ECM) ligands through transmembrane integrin receptors: an interaction which is intimately involved in cell motility, wound healing, cancer invasion and metastasis. These small (piconewton) integrin-ECM forces have been studied by molecular tension fluorescence microscopy (MTFM), which utilizes a force-induced conformational change of a probe to detect mechanical events. MTFM has revealed the force magnitude for integrin receptors in a variety of cell models including primary cells.

Quantifying T cell receptor mechanics at membrane junctions using DNA origami tension sensors.

The T cell receptor (TCR) is thought to be a mechanosensor, meaning that it transmits mechanical force to its antigen and leverages the force to amplify the specificity and magnitude of TCR signalling. Although a variety of molecular probes have been proposed to quantify TCR mechanics, these probes are immobilized on hard substrates, and thus fail to reveal fluid TCR-antigen interactions in the physiological context of cell membranes. Here we developed DNA origami tension sensors (DOTS) which bear force sensors on a DNA origami breadboard and allow mapping of TCR mechanotransduction at dynamic intermembrane junctions.

Course and Outcome of Anorexia Nervosa in Adolescents from a Tertiary-level Mental Health Setting in India: A Retrospective Chart Review.

Background: Anorexia nervosa is one of the least studied mental health conditions in the Indian setting. The objective of this study was to assess the course and outcome of anorexia nervosa in adolescents who had presented to a tertiary care child and adolescent psychiatry center over a period of 10 years.

Methods: The present study is a retrospective chart review of adolescents (up to the age of 18 years) with a diagnosis of anorexia nervosa, coded as F50.
