Bio‐Inspired Robust Non‐combustible Bioplastic with Superinsulated Energy Harvesting for Intelligent Firefighting

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study develops a novel non‐combustible chitosan‐based bioplastic (NCCB) via ethanol‐induced surface assembly. The material's inherent flame retardancy and thermally insulating, rough surface enable high‐performance TENGs. The NCCB‐TENG maintains stable output even when exposed to fire and exhibits dual sensitivity to temperature (25–200°C) and ...

Discriminating Bacteria With Functionalised Nanoporous Xerogels

Procedia Chemistry, 2012
AbstractA new colorimetric and easy-to-use solid sensor for the detection of indole-producing bacteria is described. The sensor is a nanoporous matrix with tailored pores doped with a reactant, DMACA. The sensor turns rapidly from transparent to green-blue when exposed to metabolic indole coming from bacteria cultures, both in liquid and gas phases. An

Vanadate conformation variations in vanadium pentoxide nanostructures [PDF]

, 2012
We report the comparative structural-vibrational study of nanostructures of nanourchins, nanotubes, and nanorods of vanadium oxide. The tube walls comprise layers of vanadium oxide with the organic surfactant intercalated between atomic layers.

Sol‐Gel Coating on CA‐60 Steel Surfaces: A Process for Corrosion Inhibition

Materials and Corrosion, EarlyView.
30% of the steel produced worldwide is used to replace losses due to corrosion. The application of the sol‐gel process to inhibit and delay deterioration appears as a viable methodology for protection against aggressive environments. ABSTRACT The phenomenon of corrosion causes worldwide damage, which is not only economic but also results in the loss of

On Tuning the Fluorescence Emission of Porphyrin Free Bases Bonded to the Pore Walls of Organo-Modified Silica

Molecules, 2014
A sol-gel methodology has been duly developed in order to perform a controlled covalent coupling of tetrapyrrole macrocycles (e.g., porphyrins, phthalocyanines, naphthalocyanines, chlorophyll, etc.) to the pores of metal oxide networks.

Synthesis and robocasting of YAG xerogel: one-step conversion of ceramics

Scientific Reports, 2022
An optimized sol–gel protocol was carried out to produce an yttrium aluminum garnet (YAG) xerogel from aluminum alkoxide and an yttrium salt on a semi-pilot scale. This xerogel was successfully used without prior pyrolysis as a solid load with the aid of
