The discharge of untreated dye waste from various industrial sectors into wastewater poses significant environmental and health risks. This study presents an innovative approach by developing a cost-effective and eco-friendly hybrid mesoporous nanocomposite, silver nanoparticles@mesoporous mango peel-derived carbon (AgNPs@MMC), synthesized from agricultural waste (mango peels) and urban waste (X-ray film waste). The core objectives of this work are: (i) recycling agricultural and urban waste to produce valuable materials; (ii) achieving effective removal of methyl violet 10B (MV10B) through simultaneous adsorption and photocatalytic degradation; and (iii) evaluating the antimicrobial properties of the developed material.

Bee products, abundant in bioactive ingredients, have been utilized in both traditional and contemporary medicine. Their antioxidant, antimicrobial, and anti-inflammatory properties make them valuable for food, preservation, and cosmetics applications. Honeybees are a vast reservoir of potentially beneficial products such as honey, bee pollen, bee bread, beeswax, bee venom, and royal jelly.

Article Synopsis
  • There is a growing demand for portable electrochemical sensors to monitor dopamine (DA), a neurotransmitter linked to disorders like Alzheimer's and Parkinson's.
  • The newly designed sensor features a 3D structure called 3D-PS-doped CNHN that mimics a hornet's nest, enhancing its ability to detect DA through its unique morphological design and high surface area.
  • The sensor shows impressive sensitivity with a low detection limit and can effectively recover DA from human fluids, indicating its potential for practical applications in medical monitoring.

Real-time monitoring and tracking of extreme toxins that penetrate into living cells by using biocompatible, low-cost visual detection via fluorescent monitors are vitally essential to reduce health hazards. Herein, we report a simple engineering design of biocompatible and fluorescent sensors/trackers for real-time monitoring and ultra-trace tracking (up to ppb) of extremely toxic substances (such as arsenic species) in living cells. The biocompatible As(V) sensor (BAS) design is fabricated via successful dressing/decoration process of 2-hydroxy 5-methyl isophthalaldehyde fluorescent receptor into hierarchical organic-inorganic carriers that have micro-hollow geodes, swirled caves and nest-shaped cages, and uniform cubic structures.

Owing to the high cost of precious metal catalysts for the oxygen evolution reaction (OER), the production of highly efficient and affordable electrocatalysts is important for generating pollution-free and renewable energy via electrochemical processes. A facile hydrothermal approach was employed to synthesize hybrid mesoporous iron-nickel bimetallic sulfides @ P, N-doped carbon for the OER. The prepared FeNiS@C exhibited an overpotential (η) of 250 mV at 10 mA/cm.
