The preparation of bio-based hydrogels with excellent mechanical properties, stable electrochemical and self-adhesive properties remains a challenge. In this study, nano-polydopamine-reinforced hemicellulose-based typical multistage pore structures were prepared. nanocomposite exhibit show no significant crushing phenomenon after 1000 cycles cyclic compression. Its ultimate tensile strain was 101%, which is significantly higher than that native skin. shear adhesion strength the hydrogel to...
The conversion of lignocellulose biomass to furfural can be performed using one-step and two-step strategies. A techno-economic analysis plays a crucial role in evaluating the overall economic feasibility industrial-scale production.
A lignin-extractive green reaction medium consisting of choline chloride, 5-sulfosalicylic acid, and γ-valerolactone was designed. Polyphenolic lignin obtained. The advancement DES processing has been enhanced.
Alkanolamidines, alkanolguanidines and diamines each react with CO2 to form reversible zwitterionic liquids. is chemically bound the alcohol on alkanolamidines as alkylcarbonates, while carbamates. All three classes of liquids could be reverted their non-ionic forms by thermally stripping at temperatures near 50 °C, one derivative was found irreversibly a cyclic carbonate.
Soil remediation requires technologies to restore contaminated soil a state that is environmentally acceptable. In most cases, while the can be remediated contaminant itself cannot reclaimed. However, ex situ washing with an aqueous solution of surfactant would allow easy recovery if resulting emulsion could easily and reliably broken. CO2-responsive switchable surfactants switched on off by CO2 addition removal facile breaking, but all reported examples are cationic surfactants. Because...
To achieve low regeneration energy consumption and viscosity, a novel amino-functionalized ionic liquid [TEPAH][2-MI] combined with organic solvents has been proposed for CO2 capture in this work. The results demonstrated that the absorption loading of [TEPAH][2-MI]/N-propanol (NPA)/ethylene glycol (EG) was 1.72 mol·mol–1 (28 wt %, 257 g·L–1), which much higher than monoethanolamine/water, efficiency maintained at 90.7% after fifth cycle. viscosities solution were only 3.66 7.65 mPa·s before...
Graphene oxide (GO) membranes hold promise for selective CO2 adsorption over N2 due to their carboxyl groups, making them attractive flue gas capture. However, challenges such as limited content, flexible nanosheets, and dense layer stacking hinder N2/CO2 selectivity, pressure resistance, permeability. In this study, we introduce a specific sub-nanometer framework structure within GO by in-situ growing ZIF-8 nanocrystals. This novel approach, achieved through simultaneous infiltration of...
[reaction: see text] A highly effective direct coupling of acid chloride with terminal alkynes catalyzed by PdCl(2)(PPh(3))(2)/CuI together a catalytic amount sodium lauryl sulfate as the surfactant and K(2)CO(3) base provided ynones in high yields water.
Pipelining of heavy crudes can be facilitated by preparing oil-in-water (O/W) emulsions the crude, but separation oil from water after pipelining is problematic if conventional surfactants are used. Long-chain acetamidines CO2-triggered switchable surfactants, being surface-active when CO2 present not absent. Unfortunately, in presence CO2, they stabilize water-in-oil (W/O) crude rather than desired O/W emulsions. However, absence added several compounds (Na2CO3, three long-chain...
Surfactant-free emulsions are prepared using bi-wetting particles which occupy the oil–water interface to effectively reduce interfacial area. The equilibrium position of particle at is determined by its wettability. CO2-reponsive chemical functional groups grafted onto surface silica particles. Particles with only CO2-switchable capable stabilizing oil-in-water emulsions. both CO2-responsive and hydrophobic on water-in-oil Emulsion stability disturbed when wettability altered introducing...
In this work, magnetic CuFe2O4/Ag nanoparticles activated by porous covalent organic frameworks (COF) was fabricated to evaluate the heterogenous reduction of 4-nitrophenol (4-NP). The core-shell CuFe2O4/Ag@COF successfully prepared polydopamine silver ions on CuFe2O4 nanoparticles, followed COF layer condensation. By integrating intrinsic characteristics core and layer, obtained nanocomposite exhibited features high specific surface area (464.21 m2 g−1), ordered mesoporous structure, strong...
