Dimethylamine Bismuth Iodide: A Lead-Free Perovskite Enabling Ultra-Sensitive UVC Photodetection with Low Operating Voltage and High Detectivity.

Ultraviolet (UV) photodetectors (PDs) are essential for various applications, but traditional materials face challenges in cost, fabrication, and performance. This study introduces dimethylamine bismuth iodide (DMABI) as a promising lead-free perovskite for UV PDs, particularly in the UVC region. DMABI demonstrates exceptional device parameters, including an ultralow dark current of 0.

A Meta-Analysis and Meta-Regression of Embolisation Outcomes of Pulmonary Arteriovenous Malformations.

Purpose: Embolisation is a widely utilised therapeutic intervention for pulmonary arteriovenous malformation (PAVM). We conducted a meta-analysis to evaluate outcomes of PAVM embolisation and factors associated with embolisation outcomes.

Methods: MEDLINE, EMBASE and Cochrane Central Register of Controlled Trials (CENTRAL) were searched from 2000 to July 2022 on studies that assessed embolisation outcomes of PAVM.

Proximity-induced FRET and charge-transfer between quantum dots and curcumin enable reversible thermochromic hybrid polymeric films.

This study introduces a novel strategy for developing reversible thermochromic fluorescent films by precisely controlling the nanoscale proximity of boron nitride quantum dots and curcumin molecules within a poly(3-hydroxybutyrate) matrix. The synergistic interaction and Förster resonance energy transfer between these fluorophores result in an energy transfer efficiency of ∼94%. This approach enables tunable color changes in response to temperature variations, governed by the segmental mobility of polymer chains.

Biogenically synthesized porous TiO nanostructures for advanced anti-bacterial, electrochemical, and photocatalytic applications.

This study develops environmentally benign capping technique to synthesize nanoparticles of Curcuma longa-coated titanium dioxide (CR-TiO) from titanium isopropoxide by utilizing the extract of Rosa rubiginosa flowers as reducing and chelating agent. The biogenically synthesized nanoparticles revealed excellent anti-bacterial, electrochemical, and photocatalytic properties due to the presence of porous TiO nanostructures. The sharp peaks by XRD pattern showed the crystallinity and phase purity of TiO nanoparticles.

A multi-centric, single-blinded, randomized, parallel-group study to evaluate the effectiveness of nasoalveolar moulding treatment in non-syndromic patients with complete unilateral cleft lip, alveolus and palate (NAMUC study): a study protocol for a randomized controlled trial.

Background: Cleft lip and palate (CLP) are among the most common congenital anomaly that affects up to 33,000 newborns in India every year. Nasoalveolar moulding (NAM) is a non-surgical treatment performed between 0 and 6 months of age to reduce the cleft and improve nasal aesthetics prior to lip surgery. The NAM treatment has been a controversial treatment option with 51% of the cleft teams in Europe, 37% of teams in the USA and 25 of cleft teams in India adopting this methodology.
