In the past 70 years, over 8 billion tons of plastics have been produced, majority which cannot be fully biodegraded, causing their fragments to found everywhere in biosphere, including living organisms. Herein, a group biodegradable composites were produced by blending poly(butylene adipate-co-terephthalate) (PBAT) with technical lignin through twin-screw extrusion method. Two strategies developed improve mechanical properties PBAT/lignin composites: (1) modifying via methylation reduce...
The chemical transformations of lignin in an acidic DES system.
We report a method for cleaving the C(O)-sp2C bonds of unactivated acylazaarenes via benzimidazoline intermediates using mild redox neutral catalytic system involving scandium triflate. This avoids need preactivation or transition metal catalysts, enabling efficient C-C bond cleavage in broad range substrates, including 2-acylimidazoles, 2-acylpyridines, 2-acylpyrole, and even nonchelating 3-acylindole, which direct has not been previously achieved.
Eco-friendly and good-performance resin adhesives are needed for wood manufacturing. In this study, phenol-urea-formaldehyde (PUF) were modified by adding various ratios of resorcinol. The properties PUF, phenol-resorcinol-urea-formaldehyde (PRUF) adhesives, the performances prepared plywood tested. curing behaviors structural features PUF PRUF investigated via dynamic scanning calorimetry, thermal gravimetric analysis, 13C NMR, cross polarization magic angle spinning NMR. results indicated...
The Suzuki-Miyaura coupling reactions of potassium aryltrifluoroborates with aryl bromides in water are promoted by the addition [bmim]PF6 using Pd(OAc)2 as a catalyst and Na2CO3 base under air. quantity used is crucial to efficiency catalytic system. A wide range biaryls polyaryls can be easily prepared good excellent yields.
Abstract As an energy crop, sweet sorghum ( Sorghum bicolor (L.) Moench) receives increasing attention for phytoremediation and biofuels production due to its good stress tolerance high biomass with low input requirements. Sweet possesses wide adaptability, which also has tolerances poor soil conditions drought. Its rapid growth the large storage of fermentable saccharides in stalks offers considerable scope bioethanol production. Additionally, heavy metal ability remove cadmium (Cd)...
The direct transformation of bioethanol fermentation residues for production high-quality green resins.
Polyvinyl acetate emulsion adhesive has been widely used due to its good bonding performance and environmentally friendly properties. Indeed, the can be further improved by copolymerizing with other monomers. In this study, effect of adjunction redox initiator (hydrogen peroxide–tartaric acid, H2O2–TA) on properties poly (vinyl acetate-butyl acrylate) (P (VAc–BA)) was investigated. With increasing dosage, reaction became more complete obtained film compact, as identified via SEM. The...
Abstract The valorization of lignin to replace phenol is significant in the production phenolic resins. However, a great challenge produce lignin‐based resin (LR) with suitable viscosity and high substitution rate phenol. In this study, LRs were produced using hardwood technical derived from pulping industry. Structural analysis indicated that unsubstituted para ortho carbon atoms aromatic ring influenced curing temperature activation energy kinetics thermal decomposition study implied urea...
2-Acylimidazoles are widely used as post-transformable carboxylic acid equivalents in chemoselective and enantioselective reactions. Their transformations, however, require pretreatment with highly reactive, toxic methylating reagents to facilitate C-C bond cleavage. Here, we demonstrate that such can be avoided the cleaved under neutral conditions without use of additional or catalysts. The scope reaction, including products reported literature substrates, some mechanistic insights described.
The polyculture of shellfish and seaweed together is an effective way to solve the current bottleneck in developing culture industry, determining optimal ratio important prerequisite for its application.Large-scale oyster monocultures Beibu Gulf (South China) have led environmental degradation exceeded aquaculture carrying capacity.In order cope with problem, this study designed a microcosm seaweed, trying explore both protection economic benefits.Different densities Gracilaria...
Abstract The application of non woody biomass materials in the manufacture wood‐based panels has been confirmed as an efficient carbon sequestration approach. In this study, reed straw was recommended to produce reed‐based particleboards (RPs). Sieving and hydrothermal pre‐treatments were conducted on inner layer particles reduce adverse influence waxy mechanical strength RPs. thickness swelling rate merely 1.04% (2 h), internal bonding could reach up 0.88 MPa, which met ISO requirements for...
The surface morphology of the non-conducting granular materials was analysis by SEM under low vacuum conditions. effects incident electron voltage, electronic beam spot size and atmosphere pressure on image quality EDX were investigated systematically. results show that resolution images both reduce with increase pressure; errors EDS decrease when measured
Energy consumption and pollutant emissions from buildings have caused serious impacts on the environment. Currently, research building environmental costs is quite insufficient. Based life cycle inventory of materials, fossil fuel electricity power, a calculating model for during different stages presented. A single-objective optimization generated by converting impact into cost, with same unit direct cost. Two residential buildings, one located in Beijing another Xiamen, China, are taken as...
