Reusable photocatalytic titanium dioxide–cellulose nanofiber films
Titanium dioxide (TiO2) is a well-studied photocatalyst that is known to break down organic molecules upon ultraviolet (UV) irradiation. Cellulose nanofibers (CNFs) act as an attractive matrix material for the suspension of photocatalytic particles due to their desirable mechanical and optical properties. In this work, TiO2–CNF composite films were fabricated and evaluated for photocatalytic ac...

متن کاملHierarchically Self-Assembled Nanofiber Films from Amylose-Grafted Carboxymethyl Cellulose
In this paper, we report the formation of hierarchically self-assembled nanofiber films from amylose-grafted sodium carboxymethyl celluloses (NaCMCs) that were synthesized by a chemoenzymatic approach. First, maltooligosaccharide primer-grafted NaCMCs were prepared by a chemical reaction using two kinds of NaCMCs with different degrees of polymerization (DPs) from Avicel and cotton sources. The...
متن کاملA fluorescence turn-on mechanism to detect high explosives RDX and PETN.
Detecting hidden explosive devices in war zones and transportation hubs is a pressing concern. Current efforts have focused on sensing three commonly used powerful explosives: 2,4,6-trinitrotoluene (TNT), 1,3,5-trinitro-1,3,5-triazinane (RDX) and pentaerythritol tetranitrate (PETN) (Chart 1). The need for ultratrace detection of these low-volatility compounds has resulted in an intense interest...
متن کاملBehavioural and Genetic Evidence for C. elegans' Ability to Detect Volatile Chemicals Associated with Explosives
BACKGROUND Automated standoff detection and classification of explosives based on their characteristic vapours would be highly desirable. Biologically derived odorant receptors have potential as the explosive recognition element in novel biosensors. Caenorhabditis elegans' genome contains over 1,000 uncharacterised candidate chemosensory receptors. It was not known whether any of these respond ...
