Unilateral diaphragmatic paralysis is a rare but important complication of thoracic radiotherapy, typically resulting from unintended injury to the phrenic nerve when it lies within or adjacent to the radiation field. While radiation-induced pulmonary toxicities such as pneumonitis and fibrosis are...

Purpose: In India, 4.80 million people are blind, and 4.69 million have severe visual impairment. Globally, the digital era and the advent of artificial intelligence devices offer solutions for daily challenges faced by the visually impaired, but they are often expensive. This study evaluates the ac...

Abstract The Carbon quantum dots (CQD) is prepared from ascorbic acid, and the photophysical, structural, and metal sensing behavior of the CQD is investigated in detail. The negatively charged CQD, along with the vibrant functional groups, can absorb the positive charge ferric ion (Fe3+) and copper...

Mechanical characteristics were studied for epoxy composites reinforced with cork fillers, analyzing various loading conditions of fillers ranging from 0 to 30%. The fabrication utilized a hand layup method. The results indicated that the composite mechanical properties, glass transition temperature...

We present a simple method for customizing the optical characteristics of gold-core, silver-shell (Au@Ag) nanoparticles through controlled morphosynthesis via a seed-mediated chemical reduction approach. By systematically adjusting the concentration of cetyltrimethylammonium chloride (CTAC), we obta...
