Ammonia is a colorless gas, yet it can be fatal if inhaled or ingested in high enough concentrations. Herein, a solid-state colorimetric smart wool (WL) sensor for ammonia was developed. Common hop (Humulus lupulus L.

The current study aimed to employ commercial free cellulase enzyme to partially hydrolyze (activate) the polyester cotton blended (PET/C) fibrous wastes by creation functional groups such as OH and COOH on their surfaces. The activated fibrous wastes were then modified by coating with ZnO nanoparticles (ZnO-NPs) biosynthesized by actinobacterial cultures free supernatant.

- Researchers developed smart windows with impressive features like long-lasting glow, UV protection, high clarity, and strong durability by mixing lanthanide-activated phosphor particles in a recycled polyester/cellulose nanocrystal composite made from rice straw waste.
- Cellulose nanocrystals acted as a crosslinker and drier to enhance the window's transparency and hardness, while maintaining a uniform distribution of phosphor particles to avoid clumping and ensure clarity.
- The resulting smart window showcases color changes when exposed to UV light, demonstrating effective UV shielding and quick fluorescence changes, with distinct phosphorescence at specific wavelengths, enhancing its functional properties.

- The study focused on developing a cost-effective and eco-friendly method to synthesize silver nanoparticles (AgNPs) using fungal proteins from Aspergillus fumigatus, which could be used as antimicrobial agents in textiles.
- The optimum conditions for producing AgNPs were determined, yielding predominantly spherical particles with a size under 84.4 nm, which demonstrated effectiveness against various pathogens.
- This green synthesis method offers a safer alternative to conventional techniques and has potential for large-scale production and therapeutic applications.
A simple, portable and highly sensitive naked-eye test strip is successfully prepared for optical detection of gaseous and aqueous alkaline analytes. Novel pH-sensory tricyanofuran-hydrazone (TCFH) disperse colorant containing a hydrazone recognition functional moiety is successfully synthesized via azo-coupling reaction between active methyl-containing tricyanofuran (TCF) heterocycle and diazonium salt of 4-aminobenzaldehyde followed by Knoevenagel condensation with malononitrile. UV-vis absorption spectra display solvatochromism and reversible color changes of the TCFH solution in dimethyl sulfoxide in response to pH variations.
