Excited‐State Intramolecular Proton Transfer (ESIPT) Driven Emission Switching in a Coordination Polymer for Selective Detection of Nitroaniline Isomers

Nitroaniline (NA) isomers are important, yet hazardous dye industry intermediates, require rapid and selective detection. Although conventional coordination polymers can detect NA through fluorescence quenching or wavelength shifting, however their limited signal discrimination o...

Cold atmospheric plasma for wound healing: Toward AI-guided therapeutic optimization

Acute and chronic wounds are still a major clinical problem and the therapeutic response to cold atmospheric plasma (CAP) is highly dependent on the device architecture, the delivered dose, the wound characteristics and the treatment protocol. This review critically discusses the...

Accessing Aerial Transformation of Arylmethanamines into Amides Using a Redox-Active Aryl-Substituted BIAN-Based Catalyst

Abstract The direct α-oxygenation of arylmethanamines to amides is a cornerstone transformation in organic synthesis; however, traditional methods suffer from harsh conditions, reactive reagents, and expensive transition metal catalysts. This study introduces a novel approach usi...

Synthesis and Characterization of Pure Nanoceria for Enhanced Colorimetric Detection of Malathion as a Model Organophosphorus Pesticide

ABSTRACT Organophosphorus pesticides, the largest group of pesticides, when used in excess leaves residues beyond permissible limits on agricultural produce leading to human illness and non‐compliance to safety standards. While existing detection methods are expensive and laborio...

Metal-coordinated water-assisted enhanced proton conductivity of robust Ni(II)-based 3D/2D metal-organic frameworks

Design and implementation of reconfigurable smart antenna beamforming architecture for secure node localisation applications

Smart antenna beamforming enables precise node localisation by counteracting physical layer attacks. A pattern with a narrower beamwidth is useful for securely sending data to target nodes . It is possible to cancel interference from other nearby nodes while steering deep nulls a...

Form, Structure and Agency in Mrinal Sen’s Calcutta 71

Mrinal Sen called Calcutta 71 (1972) ‘a kind of collage, a collection of apparently unrelated events and objects’. But in fact, the film bears evidence of anxious and overtly articulate composition, both in the three ‘one-day’ stories, based on literary originals and set in succe...
