Effective management of bacterial panicle blight (BPB) is critical to minimizing yield losses, yet current strategies are limited by a scarcity of resistant rice cultivars. Furthermore, while the antibiotic oxolinic acid is a key chemical countermeasure globally, its agricultural use remains unregistered in several countries. Therefore, sustainable biocontrol alternatives are urgently needed...
Reproducibility during scale-up remains a major challenge in nanoparticle synthesis due to variations in mixing efficiency, local concentration gradients, and crosslinking kinetics. This study evaluated the upscaling of chitosan nanoparticles (CNPs) prepared via the ionic gelation of chitosan with sodium tripolyphosphate (TPP) anions at a critical ratio of 2.4:1. The preparation was...
Epoxy resin and polyvinyl acetate adhesives are widely used in treating the cracks and fractures for stones antiquities. In this study, details the development, mechanical evaluation, and application methodology of high-performance epoxy resin and (PVAc) adhesives reinforced with inorganic fillers, specifically engineered for archaeological stone restoration. Epoxy resin was reinforced with...
This study deals with the green synthesis of AgNPs in an aqueous solution using leaf extract of Allium ampeloprasum to reduce silver ions and stabilize the formed nanoparticles while also determining the antioxidant activity of the nanoparticles by DPPH radical scavenging assay. The fresh leek leaves were extracted by boiling 25 g of leaves in 100 mL deionized water for 45 min at 80 °C. For...
Stroke remains one of the leading causes of global mortality and long-term disability, with growing evidence indicating that cerebrovascular injury begins long before the onset of detectable symptoms. Silent brain infarction (SBI), an asymptomatic yet radiologically identifiable form of cerebral ischemia, is recognized as a preclinical stage of stroke that reflects ongoing vascular endothelial...
Oral hygiene is fundamental to maintaining overall health, and antimicrobial mouthwashes play an important role in preventing oral microbial infections. This study aimed to develop and evaluate a natural antibacterial mouthwash based on a nanoemulsion incorporating green-synthesized silver nanoparticles (AgNPs) and Origanum vulgare (oregano) essential oil. The AgNPs were synthesized using...
Lead ion (Pb²⁺) is a very poisonous heavy metal, which is widely present in industrial wastewater and poses a serious health hazard even at low quantities. Carbon quantum dots (CQDs) offer a promising alternative as a sensor for heavy metal ion detection, as they are fluorescent, non-toxic, and can be synthesized from sustainable biomass. This study utilizes raw oil palm trunk (OPT) as a green...
