TA/Cu-XCM@βCNC nanocarrier is developed for crop protection, the introduced system enables pH-responsive controlled delivery, enhances deposition and prevents pesticide leakage.
Upgrading lignin particles with controlled morphology and amphiphilicity to investigate the stabilization mechanism in Pickering systems is reported.
The lignin–carbohydrate complexes (LCCs) typically present in the liquors produced pre-hydrolysis of biomass cause severe difficulties downstream fractionation. To address this issue, a series LCC samples were accessed from solutions obtained extractive-free pine wood meal (H-LCC) and compared with corresponding residues (B-LCC). Chromatographic spectroscopic techniques revealed that 8.2% lignins degraded at 160 °C, resulting breakage β-O-4′ linkages during pre-hydrolysis. Meanwhile,...
Global efforts to reduce carbon emissions and improve thermal comfort demand sustainable safe-to-use insulative materials. This study advances a new type of chemical binder-free lignocellulose/clay composite foam as alternative the currently used synthetic glass/mineral counterparts. Pressurized disk milling unraveled submicron "hairy" fibrillation on surface refiner mechanical pulp (RMP). Such fibrillated fibers were then subjected laying process, with kaolinite being incorporated an...
Abstract Control over particle size and shape heterogeneity is highly relevant to the design of photonic coatings supracolloidal assemblies. Most developments in area have relied on mineral petroleum‐derived polymers that achieve well‐defined chemical dimensional characteristics. Unfortunately, it challenging attain such control when considering renewable nanoparticles. Herein, a pathway toward selectable biobased physicochemical profiles proposed. Specifically, lignin fractionated, widely...
Nanochitins exhibit unique structural attributes that confer distinct physical properties to multiphase systems. Amphiphilic tannic acid (TA) serves as an excellent candidate for interfacial modification via electrostatic adsorption and complexation with nanochitin. In this study, we developed green food-safe strategies enhance the stabilizing functional performance of complexes formed through coassembly chitin nanofibers (ChNF) TA. Their interactions were systematically investigated using...
Abstract A graft copolymer was synthesized by copolymerization of starch with styrene (St) and butyl acrylate (BA), using ferrous sulfate‐hydrogen peroxide redox initiation system. The pregelled in the presence acrylonitrile (AN) aqueous alkali at high temperature before polymerization. Major factors affecting polymerization reaction were investigated. It found that a higher percentage conversion (PC), efficiency (GE) (GP) obtained controlling initiator concentration, ratio monomers...
The diversity of hemicellulose oligomers enables many potential applications, but controlling yield and oligomer molar mass is challenging. Oligomer production by hydrolysis softwoods was investigated, the evolution described a population balance model. A two-dimensional calibration method enabled measurement broadly distributed concentration simultaneously size exclusion chromatography. model describes full from initial solubilization softwood, depolymerization to ever-smaller molecules,...
Hemicelluloses consume alkali during kraft pulping and dissolve in the black liquor as a low energy fuel. Acidic pre-hydrolysis of softwood chips removes hemicelluloses but preserves cellulose content prior to pulping. This study compared mild (140 °C) with conventional commercial at two H-factors for wood thickness ranging from less than 2 mm over 6 mm. The chip increased oligomer yield showed little influence on pulp fiber yield. However, length decreased 5.6%. Kappa number reject...
We introduce Kraft lignin colloids produced by destabilization of a kraft solution pH shift from 2 to 11. The system includes particles and hydrocolloid aggregates in equilibrium (KLP), which are used control the emulsifying energy stabilize oil-in-water emulsions under high at 11 7, yielding excellent stability (at least three months with no creaming). investigate effect external energy, particle desorption, drop size, rheology on KLP-based Pickering according system’s pH. Considering...
Abstract The adsorption of locust bean gum (LBG) onto Northern Bleached Softwood Kraft (NBSK) pulp improved paper tensile and burst strength lowered refining energy by strengthening inter-fibre bonding. Adsorption kinetics isotherms were investigated to develop a fundamental understanding the mechanism. rate followed pseudo-second-order activation was 99.34 kJ·mol −1 , suggesting chemisorption. constant increased rapidly with temperature from 25 45 °C ( k = 1.93 24.03 g·mg ·min ), but amount...
