In this study, the magnetized nano-dextrin-supported boron trifluoride (nano-Fe₃O₄@dextrin/BF₃) as a green biopolymer-based catalyst is synthesized in two steps. In the first step, nano-dextrin is magnetized (nano-Fe₃O₄@dextrin), and in the second step, the BF₃ is supported to the obtained nano-Fe₃O₄@dextrin. The structure of nano-Fe₃O₄@dextrin/BF₃ is characterized by different techniques, including Fourier transform IR (FT-IR) spectroscopy, X-ray diffraction (XRD) pattern, energy dispersive X-ray (EDX) anal., SEM (SEM) imaging, mapping, vibrating sample magnetometer (VSM), and thermogravimetric anal. (TGA/DTG). The catalytic efficiency was also investigated in the synthesis of biol. active polyhydroquinoline derivatives via Hantzsch condensation reaction of aromatic aldehydes, dimedone, Et acetoacetate, and ammonium acetate under solvent-free conditions. The structure of products was confirmed by their m.ps. (MP), FT-IR, and ¹H and ¹³C NMR (NMR) spectroscopy. This procedure enjoys advantages such as short reaction time, clean and fast work-up, and easy separation of the catalyst by an external magnet.

Wang, Ruikun published the artcileForming mechanism of coke microparticles from polymerization of aqueous organics during hydrothermal carbonization process of biomass, Formula: C9H10O4, the publication is Carbon (2022), 50-60, database is CAplus.

Corn stalk was selected as a typical biomass, and the growth mechanism of coke microparticles was studied. The coke microparticles that formed from through the polymerization of aqueous organics during the hydrothermal carbonization (HTC) showed a considerable effect on the mass yield and physicochem. properties of the hydrochar. Results indicated that the average particle size of the coke microparticles rapidly increased to 6.25μm within the initial 2 h of HTC. The lower C/O at. ratio of the surface layer of the coke microparticles than that of the core, suggested that the core had a higher carbonization degree than the shell. On the basis of various measurements, the coke microparticles were inferred to have formed through the two stages of micronuclei formation and growth. Dissolved organics, including furfurals, furans, and phenols polymerized each other into aromatized macromols., and then formed solid-phase micronuclei. Subsequently, the oxygen containing groups of the micronuclei formed bonded with aqueous organic mols., as a result, the micronuclei grew up into coke microparticles. Meanwhile, the carbonization degree of the coke microparticles was enhanced due to continuous intra- and inter-mol. dehydration and decarboxylation reactions occurred between hydroxyl and carboxyl groups.

Cellat, Mustafa published the artcileProtective effect of Smilax excelsa L. pretreatment via antioxidant, anti-inflammatory effects, and activation of Nrf-2/ HO -1 pathway in testicular torsion model, Recommanded Product: 4-Hydroxy-3,5-dimethoxybenzaldehyde, the publication is Journal of Food Biochemistry (2022), 46(8), e14161, database is CAplus and MEDLINE.

The protective effects of the ethanol extract of Smilax excelsa L. (SE) leaves were investigated on testicular tissue of rats with a torsion model in this study. The chem. composition of the extract was detected by means of liquid chromatog. with tandem mass spectrometry (LC-MS/MS). SE extract was given for 21 days before torsion was created in the treatment group. The sperm parameters of the torsion group were impaired, and there was an increase in MDA level as well as a decrease in GSH level and GPx activity compared to the control group. TNF-α and NF-κB levels in the torsion group increased as compared to those in the control group. The expression levels of Nrf-2 and HO-1 were lower in the torsion group than those in the control group. The SE pretreatment group has improved sperm, oxidative stress, and inflammatory markers when compared to the torsion group, and the Nrf-2/HO-1 pathway was activated. Practical applications : Smilax excelsa L. is a plant with economic value used in traditional medicine in the treatment of stomachache, bloating, and breast cancer in Northwest Anatolia. It has an antioxidant effect due to the flavonoids and anthocyanins it contains. The protective effect against ischemia-reperfusion-induced tissue and reproductive damage in testicular tissue were demonstrated with the study. When the histol. examinations of the tissues were evaluated, it was found that morphol. structure of the tissues was retained in the treatment group. The findings indicate that SE prevents tissue damage in the torsion model by antioxidant and anti-inflammatory effects and activating Nrf-2/HO-1 pathway.

Zhang, Yifan published the artcileElectron transfer capacity of humic acid in soil micro and macro aggregates in response to mulching years, Safety of 4-Hydroxy-3,5-dimethoxybenzaldehyde, the publication is Science of the Total Environment (2022), 154927, database is CAplus and MEDLINE.

Plastic film mulching can help farmers meet food production requirements and even increase output. Although the environmental impact of this mulch has received attention, uncertainty remains about certain soil components and the course of its long-term effects. In particular, it is not clear whether the long-term use of mulching film will affect the electron transfer capacity (ETC) of natural organic matter in the soil. This study evaluated the electron-accepting capacity (EAC) and electron-donating capacity (EDC) of soil humic acid (HA) in different-size aggregates in response to different film mulching years (0-6 years). The EAC of HA in the soil showed a downward trend as mulching years increased, while the EDC fluctuated. EAC decline in microaggregates (MIA) was more significant than that of macroaggregates (MAA). Film mulching changes the phys. and chem. properties of soil and the activity of enzymes, changes the chem. structure of HA, and ultimately affects HA electron transfer. In addition, compared with that in MAA, the chem. structure of soil HA in MIA has a stronger correlation with enzyme activity and ETC and thus is more significantly affected by mulching. These results provide an in-depth understanding of the role of HA in soil aggregates of different sizes in processes related to the agricultural soil environment under mulching conditions.

Lebedeva, Daria published the artcileWaste-to-Fuel Approach: Valorization of Lignin from Coconut Coir Pith, Synthetic Route of 134-96-3, the publication is ACS Agricultural Science & Technology (2022), 2(2), 349-358, database is CAplus.

Coconut Coir Pith (CCP) is a relatively unexplored type of lignocellulosic waste from the coconut industry. As a feedstock that is highly enriched in lignin (Klason lignin content of 40.9 wt % found in this study), CCP is a potential source for renewable lignin-derived materials. We have performed a systematic study on the characterization and valorization of lignin from CCP. We have investigated two different valorization approaches: reductive catalytic fractionation (RCF) and soda pulping followed by catalytic hydrodeoxygenation. During RCF, the lignin was converted into monomeric products in 7.6 wt %. Using soda pulping conditions, we were able to isolate lignin from CCP in 74% yield. Subsequent hydrotreatment of the lignin over a Pt/MoO₃/TiO₂ catalyst resulted in the formation of hydrogenated oil in 43 wt % yield, suitable for the production of biobased diesel fuels and lubricant base oils.

Cao, Ying published the artcileSmart anticorrosive epoxy coating based on environmental-stimuli-responsive copolymer assemblies for controlled release of corrosion inhibitors, Related Products of ethers-buliding-blocks, the publication is Macromolecular Materials and Engineering (2022), 307(7), 2100983, database is CAplus.

Inspired by the various applications of self-assembled amphiphilic polymers in aqueous solution, a novel ”semi-amphiphilic” copolymer is designed, which can self-assemble in organic systems by taking advantage of the compatibility difference between epoxy and the units with different structures in the polymer chains. A novel kind of polymer, poly(syringaldehyde methacrylate)-co-poly(dopamine methacrylate) is prepared by reversible addition-fragmentation chain transfer polymerization, which contains aldehyde groups and is further used to prepare the polymer/guanine conjugate by forming the Schiff base. The polymer/guanine conjugate is semi-amphiphilic, since the compatibility between dopamine methacrylate unit and epoxy is better than that between syringaldehyde methacrylate and epoxy, and therefore assemblies are formed in the organic system when it is added into the epoxy resin to prepare the anti-corrosive coating. The imine linkage is responsible for the pH-controlled release of the corrosion inhibitors, namely guanine, from the core of the assemblies. The self-assembled behaviors of the semi-amphiphilic copolymer in epoxy are investigated by dynamic light scattering and SEM. The stable encapsule and controlled-release of the inhibitors are confirmed by UV spectrophotometry. The properties of the smart coatings are comprehensively studied.
