Highly alkynyl-functionization of cellulose nanocrystals and advanced nanocomposites thereof via click chemistry
A series of reactive GAP (glycidyl azide polymer)/PTPB (propargyl-terminated polybutadiene) nanocomposites reinforced by alkynylated cellulose nanocrystals (ACNC) were synthesized by Huisgen click chemistry. High-efficiency substitution (more than 80%) of the hydroxyl groups by alkynyl groups on the surface of CNC was realized through the esterification reaction between the alkyny...

Heterogeneous Structure and Miscibility of Phenylboronic Acid-Rich Chitosan Nanoparticles as Revealed by Advanced Solid-State NMR
By using advanced solid-state NMR techniques, the heterogeneous structure and inter-polymer miscibility of chitosan-poly (N-3-acrylamidophenyl-boronic acid) nanoparticles
(CS-PAPBA NPs) were investigated. The 13C CPMAS experiments indicate the conformational
change of chitosan when incorporated with phenyl boronic acid. Two-dimensional (2D) 13C-1H HETCOR experiments further demonstrate that a port...

234. In-Situ Growth of Few-Layered MoS2 Nanosheets on Highly Porous Carbon Aerogel as Advanced Electrocatalysts for Hydrogen Evolution Reaction.
Molybdenum disulfide-based hybrids, acting as cost-effective and acid-stable electrocatalysts for hydrogen evolution reaction (HER), have been developed fast for providing sustainable hydrogen energy in recent years. Herein, few-layered molybdenum disulfide (MoS2) nanosheets/carbon aerogel (CA) hybrids were successfully obtained through the combination of sol?gel process, aging, freeze-drying, hig...

Freestanding bacterial cellulose–polypyrrole nanofibres paper electrodes for advanced energy storage devices
Abstract
Advanced binder-free electrode materials with high mass-loading (~10 mg cm?2) have proved to be extremely important in determining the performance of pseudo-capacitors. In this work, freestanding and highly conductive paper electrodes with high mass loading in the range of 7–12 mg cm?2 are prepared using bacterial cellulose–polypyrrole nanofibres in combina...

Studies on Cure Kinetics of Diglycidyl Ether of 4,4 '-Bisphenol/4,4 '-Diaminobiphenyl Using the Advanced Isoconversional Method
The cure kinetics of a rigid-rod epoxy monomer, diglycidyl ether of 4,4'-bisphenol (DGEBP), and the curing agent with the similar rigid-rod group, 4,4'-diaminebiphenyl (DABP), was studied using an advanced isoconversional method (AICM). DGEBP/DABP curing system was carried out by means of differential scanning calorimetry (DSC). Three exothermic peaks were depicted by nonisothermal DSC studies: th...

Studies on Cure Kinetics of Poly(phenylene ether)/Epoxy Resin System Using an Advanced Iso-Conversional Method
The kinetics and mechanism of poly(phenylene ether)/epoxy resin (PPE/EP) cure system were investigated using an advanced iso-convensional method (AICM). The curing experiments of a PPE/EP cure system with different PPE/EP ratios were carried out by means of non-isothermal differential scanning calorimetry (DSC) with different heating rates of 5, 10, 15 and 20 degrees C/min. From the DSC curves, it...

[Advanced Materials] Organic/inorganic Hybrid Hollow Spheres Prepared from TiO2-stabilised Pickering Emulsion Polymerization
Organic/inorganic hybrid hollow spheres are prepared from TiO2-stabilized Pickering emulsion polymerization. By self-organization of TiO2 nanoparticles at the interface of oil (monomer and solvent) and water, O/W colloidosomes are formed as polymerization vessels to obtain organic/inorganic hybrid hollow spheres. The diameter and mechanical stability of hybrid hollow spheres can be tailored ...
