In view of the problem marine plastic pollution and oil resource depletion, an innovative attempt was made to obtain biobased seawater-degradable polyesters by installing lactic acid (LA) into poly(butylene succinate) (PBS) backbone synthesizing a series random copolyesters named succinate-l-lactide)s (PBSLs). Herein, LA units are chosen as readily hydrolyzable points according our theoretical calculation. The obtained PBSL preserve structure PBS when inserted this main chain mostly with...
Abstract In order to promote the degradation of PLA in seawater, a series seawater-degradable polyester blends PVA/PLA were prepared by blending biodegradable polylactic acid (PLA) with water-soluble modified polyvinyl alcohol (PVA) this paper. ADR 4370S was introduced bring certain degree improvement compatibility blends. The results test natural seawater for 180 days show that weight loss is much higher compared pure PLA. PVA can be used as an effective hydrolysis accelerator matrix,...
ABSTRACT We investigated the degradation behavior of biodegradable poly(butylene adipate terephthalate) (PBAT) and its composites containing starch (PBAT–starch) calcium carbonate (PBAT–CaCO 3 ). The test splines were immersed in six different water bodies with various microbial compositions salt concentrations for a 56 week period to obtain consistent experimental data. results show that pure PBAT degraded very slowly bodies, maximum weight loss only 4.7% over study period. Strips...
A series of new biobased polyamide 10T-<italic>co</italic>-56 were synthesized with various comonomer compositions by a one-pot polycondensation reaction, and their structures, crystalline melting behavior systematically investigated.
The internal CC double bond in 3-aryl-1,2-allenes was highly regioselectively fluorohydroxylated to afford 2-fluoroalken-3-ols 37−88% yields by using Selectfluor as the electrophilic reagent. regioselectivity may be determined electronic effect, while reactivity controlled stabilization effect of aryl group allylic cationic intermediates.
Aiming at biobased semiaromatic polyamides with high performance from furan derivatives and studying the effect of ratio rings to benzene on properties polyamide, a series poly(decamethylene terephthalamide/decamethylene 2,5-furandicarboxamide) copolyamides (PA10T/10Fs) ring content ranging 0 100 mol % were prepared 2,5-furandicarboxylic acid derivatives, terephthalic acid, 1,10-decanediamine via two-step polymerization method. Their molecular weight, intrinsic viscosity, composition,...
Imputation of missing data has long been an important topic and essential application for intelligent transportation systems (ITS) in the real world. As a state-of-the-art generative model, diffusion model proven highly successful image generation, speech time series modelling etc. now opens new avenue traffic imputation. In this paper, we propose conditional called implicit-explicit This exploits both implicit explicit feature simultaneously. More specifically, design two types extraction...
This Note examines the long-term impact of Japanese War Aggression against China on inbound tourists from Japan to Chinese regions. Difference-in-differences estimates reveal that regions suffered more civilian casualty rate due invasion during 1937–1945 received fewer Japan. The bilateral relation, cultural exchanges, and educational programs are confirmed be essential mechanism variables.
ABSTRACT Solar‐driven seawater desalination is considered an promising technology coping with water scarcity due to the sustainability of solar energy and its substitutability for fossil fuels. Nevertheless, complex fabrication, high cost low efficiency solar‐driven evaporator limit large‐scale application. Herein, PDA/PU composite foam porous three‐dimensional structure developed achieve high‐efficient evaporation. Thereinto, hydrophilic PDA contributes real absorption, provides extremely...
Different from the reaction of 2,3-allenoic acids with Selectfluor, 4-fluoro-2(5H)-furanones and (E)-3-fluoro-4-oxo-2-alkenoates were highly selectively generated 2,4-disubstituted 2,3-allenoates Selectfluor under different conditions in moderate yields. The 2,4,4-trisubstituted afforded corresponding up to 95% yield conditions. scope substrates has been carefully explored. Due more readily availability as compared acids, new prepared. Based on isolation characterization minor...
