Lee, Jyun-Ting published the artcileHigh-efficiency cycling piezo-degradation of organic pollutants over three liters using MoS₂ /carbon fiber piezocatalytic filter, Quality Control of 79917-90-1, the publication is Nano Energy (2022), 107280, database is CAplus.

Piezocatalysis has great potential com. application for the high-efficiency degradation of organic pollutants in a dark environment. However, the recycling of catalyst materials and the subsequent generation of secondary pollution remain challenging. In this study, MoS₂ nanoflowers (NFs)/carbon fiber was synthesized to develop a piezocatalytic filter that can recycle decomposed wastewater easily without generating secondary pollutants in treated water. The MoS₂/carbon fiber was constructed in pipelines to form the piezoelec. degradation system, which demonstrated a high efficiency in decomposing organic mols. in wastewater through natural water flow. The piezocatalytic filters in the circulatory system completely degraded a large amount of dye solution (1000 mL) in 40 min and can repeat three-times degradation with the total organic carbon value decreased by 90%. The theor. calculation indicated that MoS₂ grew on carbon fiber, which exhibited a bending moment effect under natural water-flow-induced pressure. This established considerable piezoelec. potential at MoS₂ NFs active edge sites and MoS₂-carbon fiber interfaces, triggering electron-hole pair separation under the internal elec. field. The MoS₂/carbon fiber piezoelec. catalyst is advantageous for its reusability and recyclability, thus preventing secondary pollution and adverse effects on water bodies during practical high-flux wastewater treatment.

Qian, He-Sheng published the artcileAnalysis of pyrolyzates for polysulphoneamide fiber by Py-GC/MS, Related Products of imidazoles-derivatives, the publication is Journal of Donghua University (2006), 23(2), 63-67, database is CAplus.

Pyrolysis of polysulfoneamide fiber has been investigated using pyrolysis gas chromatog.-mass spectroscopy at the different temperatures from 420°C to 750°C. Its compositions of pyrolyzates have been analyzed. At 420°C, pyrolysis of mol. chain could not completely take place, 12 compounds of pyrolysis have only been identified. When the temperature increases, the compositions of pyrolyzate increase sharply. Several compounds, especially sulfur dioxide, benzene, aniline, benzoic acid, 1,4-benzene dicaronitrile, N-phenyl-acetamide, diphenylamine, benzo[g]isoquinoline, N-phenyl-benzamide, N-(4-cyanophenyl)benzamide, could be formed. The degradation mechanisms which are determined by structure and amount of the thermal decomposition products are described. During pyrolysis, for polysulfoneamide, polymeric chain scissions take place as a successive removal of the monomer units from the polymeric chain. The chain scissions are followed by secondary reactions, which lead to a variety of compounds Addnl. reactions can also take place during pyrolysis.

Song, Xiangbo published the artcileA highly effective approach to enhance the performance of biomass-derived acid for fructose conversion to 5-hydroxymethylfurfural, Product Details of C8H15ClN2, the publication is Fuel Processing Technology (2022), 107318, database is CAplus.

Synthesis of 5-hydroxymethylfurfural (HMF) from carbohydrate is one of vital step for bio-refinery development. In this work, a novel strategy was developed for catalytic conversion of fructose to HMF in 2-butanol. The inexpensive ionic liquids were used to adjust the acidity of biobased acid catalyst for enhancing the dehydration of fructose to HMF. The combination of 1-butyl-3-methylimidazolium chloride ([Bmim]Cl) with oxalic acid afforded an excellent HMF yield of 97.1% at 98.7% fructose conversion under mild conditions of 100°C and 60 min, owing to the enhanced dissociation ability of oxalic acid by [Bmim]Cl. A possible dissociation mechanism of oxalic acid induced by [Bmim]Cl was proposed based on control experiments and detailed analyses with NMR and FT-IR techniques. It involved that the [Bmim]Cl interacted with oxalic acid through hydrogen bond, which decreased the electron d. of oxygen atom on hydroxyl group and weakened the O-H bond, thus making the hydrogen in the O-H group to easily dissociate in the form of H⁺. Moreover, the reusability of oxalic acid and [Bmim]Cl was demonstrated, and both could be reused up to six times without significant loss in activity.

Traditional methods of disease diagnosis are both time-consuming and labor-intensive, and many tests require expensive instrumentation and trained professionals, which restricts their use to biomedical laboratories Because patients can wait several days (even weeks) for the results, the consequences of delayed treatment could be disastrous. Therefore, affordable and simple point-of-care (POC) biosensor devices could fill a diagnostic niche in the clinic or even at home, as personal glucose meters do for diabetics. These devices would allow patients to check their own health conditions and enable physicians to make prompt treatment decisions, which could improve the chances for rapid recovery and cure. Compact disks (CDs) provide inexpensive substrate materials for the preparation of microarray biochips, and conventional computer drives/disk players can be adapted as precise optical reading devices for signal processing. Researchers can employ the polycarbonate (PC) base of a CD as an alternative substrate to glass slides or silicon wafers for the preparation of microanal. devices. Using the characteristic optical phenomena occurring on the metal layer of a CD, researchers can develop biosensors based on advanced spectroscopic readout (interferometry or surface plasmon resonance). If researchers integrate microfluidic functions with CD mechanics, they can control fluid transfer through the spinning motion of the disk, leading to “lab-on-a-CD” devices. Over the last decade, the authors’ laboratory has focused on the construction of POC biosensor devices from off-the-shelf CDs or DVDs and standard computer drives. Besides the initial studies of the suitability of CDs for surface and materials chem. research (fabrication of self-assembled monolayers and oxide nanostructures), an ordinary optical drive, without modification of either the hardware or the software driver, can function as the signal transducing element for reading disk-based bioassays quant. In this Account, the authors first provide a brief introduction to CD-related materials chem. and microfluidics research. Then the authors describe the mild chem. developed in the authors’ laboratory for the preparation of computer-readable biomol. screening assays: photochem. activation of the polycarbonate (PC) disk surface and immobilization and delivery of probe and target biomols. The authors thoroughly discuss the anal. of the mol. recognition events: researchers can “read” these devices quant. with an unmodified optical drive of any personal computer. Finally, and critically, the authors illustrate the authors’ digitized mol. diagnosis approach with three trial systems: DNA hybridization, antibody-antigen binding, and ultrasensitive lead detection with a DNAzyme assay. These examples demonstrate the broad potential of this new anal./diagnostic tool for medical screening, on-site food/water safety testing, and remote environmental monitoring.

Wang, Shizhuo published the artcileExperimental and theoretical study on the catalytic degradation of lignin by temperature-responsive deep eutectic solvents, COA of Formula: C8H15ClN2, the publication is Industrial Crops and Products (2022), 114430, database is CAplus.

Lignin is a renewable biomass resource with excellent application potential; however, the extremely complex structure of lignin renders it difficult to effectively degrade and use. In this context, it is necessary to identify a catalyst that can be easily recovered to increase the lignin degradation rate. In this paper, two temperature-responsive deep eutectic solvents (TRDESs), which can form homogeneous phases with reactants at a high temperature and sep. from the reaction system at low temperature, were designed to catalyze lignin degradation Based on the |HOMO-LUMO| gap, [Bmim]Cl and ChCl, which have a high catalytic activity, were selected from 22 deep eutectic solvents (DESs). [Bmim]Cl-EDTA (mole ratio = 1:1) was obtained by combining [Bmim]Cl and EDTA. ChCl-SA (mole ratio = 1:1) was obtained by combining ChCl and salicylic acid (SA). Results of COSMO-SAC modeling calculations and solubility experiments indicated that TRDESs can respond to temperature Specifically, these solvents can form a homogeneous phase with the reactants at high temperatures, thereby increasing the number and uniformity of the reaction sites. Moreover, the solvents can be separated from the reaction system at low temperature, which enables efficient recycling of the catalyst. Results of lignin degradation experiments indicated that the catalytic performance of [Bmim]Cl-EDTA is higher than that of the other DESs: the degradation rate of lignin is 83.63%, and the catalyst exhibits a satisfactory catalytic effect even after multiple cycles.
