This work introduces a simple and green method for the preparation of fully biobased vitrimer material demonstrates potential application recoverable adhesives.
To date, all epoxy vitrimer systems reported in the literature rely on addition of significant amounts catalysts to achieve dynamic transesterification reaction (TER). However, used vitrimers are often toxic and have poor miscibility with organic compounds, they may further comprise application performance like corrosion resistance. Moreover, reprocessing recycling properties highly dependent loading amount type catalyst. In this study, two hyperbranched (HBE) prepolymers synthesized then...
The design of high glass transition temperature (Tg) thermoset materials with considerable reparability is a challenge. In this study, novel biobased triepoxy (TEP) synthesized and cured an anhydride monomer in the presence zinc catalyst. TEP exhibits Tg (187 °C) comparable strength modulus to bisphenol A epoxy. By adopting vitrimer chemistry, cross-linked polymer are imparted significant stress relaxation via dynamic transesterification. It noted that closely related repairing temperature,...
Halogenated disinfection byproducts (DBPs) are generated via reactions with natural organic matter (NOM) in chlorine of drinking water. How large NOM molecules converted to halogenated aliphatic DBPs during chlorination remains a fascinating yet largely unresolved issue. Recently, many relatively toxic aromatic have been identified chlorinated waters, and they behave as intermediate decompose DBPs. There is still one gap between In this study, nine nonhalogenated compounds were new...
The unintended formation of disinfection byproducts (DBPs) may compromise the safety drinking water. Since no specified DBPs have been found to be responsible for overall adverse effects and over half total organic halogen (TOX) remains unidentified, DBP mixture toxicity is gaining increasing interest as a potential indicator how risky water might be. In this study, new approach evaluating mixtures was developed by combining freeze-drying or rotoevaporation pretreatment with an in vivo...
Although >700 disinfection byproducts (DBPs) have been identified, >50% of the total organic halogen (TOX) in drinking water chlorination is unknown, and DBPs responsible for chlorination-associated health risks remain largely unclear. Recent studies revealed numerous aromatic halo-DBPs, which generally present substantially higher developmental toxicity than aliphatic halo-DBPs. This raises a fascinating important question: how much TOX chlorinated can be attributed to halo-DBPs? In this...
Sulfur hexafluoride (SF6) is the most potent greenhouse gas regulated under Kyoto Protocol, with a high global warming potential. In this study, SF6 emissions from China were inventoried for 1990-2010 and projected to 2020. Results reveal that highest emission contribution originates electrical equipment sector (about 70%), followed by magnesium production sector, semiconductor manufacture (each about 10%). Both agreements discrepancies found in comparisons of our estimates previously...
Reducing nitrous oxide (N2O) emissions offers the combined benefits of mitigating climate change and protecting ozone layer. This study estimates historical future N2O explores mitigation potential for China's chemical industry. The results show that (1) from 1990 to 2012, industrial in China grew by some 37-fold 5.07 174 Gg (N2O), with total accumulated 1.26 Tg, (2) 2012 2020, projected are expected continue growing rapidly 561 under current policies assuming no additional measures. this...
Acetaminophen is widely used to treat mild moderate pain and reduce fever. Under the worldwide COVID-19 pandemic, this over-the-counter reliever fever reducer has been drastically consumed, which makes it even more abundant than ever in municipal wastewater drinking water sources. Chlorine most oxidant disinfection, chlorination generally causes degradation of organic compounds, including acetaminophen. In study, a new reaction pathway acetaminophen, i.e., oxidative coupling reactions via...
Imparting repairability to a thermoset coating without compromising other properties is desirable. In this work, catalyst-free and repairable epoxy based on vitrimer chemistry was developed by using mixture of bisphenol A (DER) hyperbranched (HBE) as matrix, succinic anhydride (SA) curing agent. The abundant hydroxyl groups in the HBE accelerate both rates dynamic transesterification. presence DER ensures low viscosity coating, its high value results formation sufficient ester bonds after...
Acer truncatum Bunge seed oil (ASO) is rich in ω-9 (53.93%) and ω-6 (30.7%) fatty acids (FAs) characterized by 3-7% nervonic acid (NA, C24:1ω-9). Evidence suggests that FAs such as NA participate processes of cognitive improvement; however, their mechanism remains ambiguous. In this study, we investigated the effect ASO on rat memory change lipid profiling underlying metabolism. After was administrated to rats for one, three seven days, capacity learning significantly increased via MWM test....
Four linear polyurea elastomers synthesized from two different diisocyanates, chain extenders and a common aliphatic amine-terminated polyether were used as models to investigate the effects of both diisocyanate structure aromatic disulfide extender on hard segmental packing self-healing ability. Both direct investigation segments indirect mobility soft dynamics carried out compare levels packing, leading agreed conclusions that correlated well with abilities polyureas. bonds had significant...
The objective of this study was to identify potential biomarkers and possible metabolic pathways malignant benign thyroid nodules through lipidomics study. A total 47 papillary carcinomas (PTC) 33 control check (CK) were enrolled. Plasma samples collected for UPLC-Q-TOF MS system detection, then OPLS-DA model used differential metabolites. Based on classical statistical methods machine learning, characterized related identified. According the spectrum, 13 metabolites identified between PTC...
Pharmaceuticals have been considered a priority group of emerging micropollutants in source waters recent years, while their role the formation and toxicity disinfection byproducts (DBPs) during chlorine remains largely unclear. In this study, contributions natural organic matter (NOM) pharmaceuticals (a mixture ten representative pharmaceuticals) to overall DBP drinking water chlorination were investigated. By innovatively "normalizing" exposure constructing kinetic model, we able...
