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,...
Since the nanomaterial has become one of most popular topics, gold nanomaterials have always been a research hotspot. Gold nanostars (GNSs) as formations nanoparticles stepped on stage due to its remarkable property. By using Turkevich method, Brust seeded growth method and seedless-based with proper specific modification, GNSs could be produced for different requirements. These present various properties under modification: high physical chemical stability, biocompatibility ability...
A major obstacle for the use of single‐wall carbon nanotubes (SWCNTs) in electronic devices is their mixture different types electrical conductivity that strongly depends on helical structure. The existence metal impurities as a residue metallic growth catalyst may also lower performance SWCNT‐based devices. Here, it shown by using silicon oxide (SiO x ) nanoparticles catalyst, metal‐free semiconducting and SWCNTs can be selectively synthesized chemical vapor deposition ethanol. It found...
In this paper, an effective method for preparing poly (p-phenylene terephthalamide) -co- (dodecanedioyl) decylamine (PA10T/1012)/graphene oxide (GO) composites by pre-dispersion and one-step in situ polymerization was proposed the first time. During process of polycondensation, condensation between terminal amino groups PA10T/1012 chains oxygen-containing functional GO allowed nylon to be grafted onto graphene sheets. The effects polymer grafting on thermal mechanical properties...
In the context of "Carbon Emissions Peak" and Neutrality", grazing exclusion (GE) has been applied widely to rehabilitate degraded grasslands increase carbon sequestration. However, on QingZang Plateau (QZP), impacts GE dynamics alpine are poorly understood, particularly at a regional scale. To fill this knowledge gap, we evaluated responses sequestration in different across QZP by using meta-analysis. The effects ecosystem fractions were dependent duration, grassland types climate factors....
Abstract The marine pollution caused by traditional plastics is becoming increasingly serious, and the fundamental way to solve this problem look for plastic substitutes that can degrade in environment. Herein, a series of high-molecular-weight poly(butylene succinate- co -diethylene glycol succinate) (PBDS) was obtained introduction low-cost diethylene (DEG) into main chain (PBS), which aimed obtain materials be degraded both compost seawater. research showed increase DEG content reduced...
Abstract The application and promotion of biodegradable plastics are hindered by the imbalance between their mechanical degradation performance imbalance, as well high costs. Herein, a series poly(ethylene adipate‐co‐terephthalate) (PEAT) copolyesters with excellent properties synthesized one‐step melt polycondensation. influence proportion aliphatic groups in molecular chain on structure properties, especially performance, was studied. flexibility degradability PEAT increases increasing...
The biogeographic characteristics of soil microbial biomass stoichiometry homeostasis and also its mechanisms are commonly thought to be key factors for the survival strategies resource utilization microbes under extreme habitat. In this work, we conducted a 5,000-km transect filed survey in alpine grassland across Qinghai-Tibet Plateau 2015 measure carbon (MBC) nitrogen (MBN) steppe meadow. Based on differences climate conditions between meadow, variation coefficient was calculated...
A honeycomb-like single-wall carbon nanotube (SWCNT) network was constructed. Different from random SWCNT networks, the shows much higher conductivity, transparency and electrical response to chemical doping.
A new strategy to mitigate the impact of matrix effects and a high-accuracy quantification method for elements in soil by LIBS called PCA-GS-ELM are proposed.
Abstract In order to shorten the degradation incubation period of existing seawater‐degradable materials and achieve “disappearance” in seawater as soon possible, based on successful introduction hydrolyzed sites GA into PBS main chain obtain PBSG copolymer matrix, water‐soluble PVA is introduced finally a series PBSG/PVA blends, aiming promote hydrolysis process polyester matrix by dual action easily site GA. Compared with pure polyester, blends exhibt rapid loss mechanical properties,...
