COMPOSITION AND MICROSTRUCTURE OF STAGHORN URINARY STONES. THEORIES OF GROWTH

Тонкие химические технологии, 2013
For the first time the composition and microstructure of large (more than 2 cm) urinary stones, including staghorn stones, were studied according to their volume by a set of techniques (X-ray, X-ray microanalysis, scanning electron microscopy, infrared ...

Green Synthesis of Ag/AgCl Nanoparticles From Argan Oil Waste: Characterization, Antibacterial, and Cytotoxicity Activities

Food Science &Nutrition, Volume 13, Issue 12, December 2025.
Ag/AgCl nanoparticles were biosynthesized using argan‐derived saponins and characterized by UV–Vis, FTIR, XRD, SEM/EDS, and TEM, confirming spherical structures averaging 12.3 ± 7.6 nm. The nanomaterials displayed a characteristic surface plasmon resonance at 400–450 nm and crystalline Ag/AgCl phases. Antibacterial performance against Gram‐positive and

Redox Active Polyaniline‐Chitosan Supported Nano Silver Composites with Tunable Surface Structure and Catalytic Activity

Macromolecular Chemistry and Physics, Volume 226, Issue 23, December 5, 2025.
This study elaborates on the structure‐function role of (bio)polymer supports on the catalytic activity of polyaniline‐chitosan nanocomposites (NCs) that contain Ag nanoparticles (Ag@PNI‐(x)‐CHT). These NCs can be tailored to enhance selectivity in reductive transformations of model dyes: methylene blue (MB) and p‐nitrophenol (PNP).

A Comprehensive Study of Quantum Dots: Ranging From Synthesis to Applications in Electrochemical Biosensors in the Detection of Biomolecules, Gastrointestinal Diseases, and Electrophysiology

Nano Select, Volume 6, Issue 12, December 2025.
Quantum dots (QDs) typically refer to extremely small semiconductor particles, often no larger than 10 nm. The development of efficient biosensors for the sensitive and selective detection of biomolecules is essential for fundamental research in analytical chemistry, biomedicine, clinical diagnosis, and electrophysiology.

Synergistic Effects of Bacillus cereus Mn‐5 PGPR‐Derived Silver Oxide Nanoparticles on Tomato Plant Growth, Stress Resilience and Nutritional Enhancement

Journal of Sustainable Agriculture and Environment, Volume 4, Issue 4, December 2025.
ABSTRACT Introduction Agricultural crops face increasing environmental stresses, such as soil salinity and heavy metal contamination, aggravated by climate change and threatening food security. While PGPRs are eco‐friendly agrochemical substitutes, their efficacy in the field is inconsistent.
