Notable Reactivity of Acetonitrile Towards Li2O2/LiO2 Probed by NAP XPS During Li-O-2 Battery Discharge

One of the key factors responsible for the poor cycleability of Li-O-2 batteries is a formation of byproducts from irreversible reactions between electrolyte and discharge product Li2O2 and/or intermediate LiO2. Among many solvents that are used as electrolyte component for Li-O-2 batteries, acetonitrile (MeCN) is believed to be relatively stable towards oxidation. Using near ambient pressure X-ray photoemission spectroscopy (NAP XPS), we characterized the reactivity of MeCN in the Li-O-2 battery. For this purpose, we designed the model electrochemical cell assembled with solid electrolyte. We discharged it first in O-2 and then exposed to MeCN vapor. Further, the discharge was carried out in O-2 + MeCN mixture. We have demonstrated that being in contact with Li-O-2 discharge products, MeCN oxidizes. This yields species that are weakly bonded to the surface and can be easily desorbed. That’s why they cannot be detected by the conventional XPS. Our results suggest that the respective chemical process most probably does not give rise to electrode passivation but can decrease considerably the Coulombic efficiency of the battery.

Ethylene/propylene separation using mixed matrix membranes of poly (ether block amide)/nano-zeolite (NaY or NaA)

Generally, the energy and capital intensive cryogenic distillation process is applied to separate light olefins. To lower the cost of light olefin production, mixed matrix membranes (MMMs) incorporating nano-zeolite (NaY or NaA) into a rubbery poly (ether block amide) (PEBA 2533) were fabricated to separate a propylene/ethylene mixture. The effect of additive content and kind, MMM thickness, and operating temperature and pressure on the separation performance of the synthesized membranes for a propylene/ethylene mixture were investigated. As an additive, NaY was found to be more effective than NaA. Interestingly, the result of pure gas adsorption was consistent with the permeation performance of the membranes. Membranes with 6 wt% NaY showed the highest C3H6/C2H4 selectivity in all synthesized membranes (3 wt%-10 wt%), on which, the C3H6/C2H4 selectivity was increased from 2.3 to 13.1, the permeability of propylene increased from 194 barrer to 262 barrer and the permeability of ethylene decreased from 85 barrer to 19.8 barrer when the propylene concentration in feed mixture increased from 10 mol% to 80 mol% at -35 degrees C and 0.2 MPa. This membrane has the potential to separate propylene and ethylene in industry, and this work will push forward the membrane separation process for olefin production.

Grafting Drugs to Functionalized Single-wall Carbon Nanotubes as a Potential Method for Drug Delivery

The mesalazine and fluvoxamine drugs were grafted to single-walled carbon nanotubes (SWCNTs) aiming at precise drug delivery. First, carboxylic groups in SWCNT were converted to corresponding acyl chlorides. Next, in order to form the amide bonds, acyl chloride-SWCNTs were mixed with chemotherapeutic agents having NH2 and NH functional groups. Then, the covalently grafted drugs to SWCNT were characterized by UV-Vis, IR spectroscopy, and transmission electron microscopy methods. Finally, the prepared organic compounds were used for releasing drugs at pH: 1.3, which is corresponding to clinical aspects of the human body, and were examined for the potential of drug delivery in patients. Accordingly, the in-vitro kinetic as well as the mechanism of the released drugs were investigated.

Diagnosis of normal and malignant human gastric tissue samples by FTIR spectra combined with mathematical models

Since the diagnosis of gastric cancer in most cases happens in advanced stages and the pathologist judgment plays the major role in the diagnosis, Fourier Transform Infrared (FTIR) attenuated total reflectance (ATR) spectroscopy as a new, fast, non-invasive, and accurate diagnosis and screening tool was used to compare gastric samples in this study.Data modeling was performed based on the Principal Component Analysis (PCA), Support Vector Machines (SVM), and k-nearest neighbor algorithm (KNN) on the spectra of sixty fixed gastric tissue samples. Malignancy was characterized by the peaks that are mainly related to amide III and protein structure at around 1285 cm(-1) and 1339 cm(-1), delta (CH2), lipids, fatty acids, and delta (CH) at around 1439 cm(-1). Spectra comparison also indicates differences in malignant tissue’s peak positions for CH2 wagging, amide II and amide I as well as the CH scissoring of the acyl chain of lipids. The statistical analysis results confirm this modeling method to distinguish about 81.7% of the normal and malignant samples just with one feature and suggest that ATR-FTIR spectroscopy may be a potentially useful tool for the diagnosis of gastric cancer.

Effect of reactive rejuvenators on structure and properties of UV-aged SBS modified bitumen

This paper mainly investigates the effect of the reactive rejuvenator diphenyl methane diisocyanate (MDI) and 1,4-butanediol diglycidyl ether (BUDGE) on chemical structures of aged SBS and rejuvenated structures, rejuvenation mechanisms, physical and rheological properties of UV-aged SBS modified bitumen (SMB). Fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS) show the hydroxyl and carbonyl groups have formed on aged SBS, which indicates that the broken-chain structures of SBS have formed after UV radiation. Meanwhile, the disappeared hydroxyl groups and formed amide bond in FTIR spectrum of MDI rejuvenated SBS, and the associated hydroxyl groups and another appeared carbonyl groups in FTIR spectrum of BUDGE rejuvenated SBS indicate MDI and BUDGE can act as a bridge to connect the broken-chain SBS together at 150 degrees C. Moreover, the performance results show rejuvenation temperature and time have little impact on the physical properties of rejuvenated SMB whatever the rejuvenator is selected. With the increasing content of MDI, the softening point of rejuvenated SMB can be improved and the ductility at low temperature remains almost unchanged. However, the softening point of rejuvenated SMB decreases and the ductility increases as the rising content of BUDGE. Phase angle results indicate MDI can further increase the elasticity of aged SMB, and BUDGE can to some extent restore the viscosity characteristic. From the results of fatigue and rutting performance, 1% BUDGE weakens the fatigue limit temperature of aged SMB from 20.1 degrees C to 14.9 degrees C and 1% MDI increases the rutting limit temperature from 79.6 degrees C to at least 80 degrees C, which indicates BUDGE and MDI can respectively help improve the fatigue resistance and rutting resistance. Based on the analysis of FTIR spectra and the relative functional group indexes, the results show the increasing concentration of INH-CO in MDI rejuvenated SMB and IC-O-C in BUDGE rejuvenated SMB, indicating the chemical reaction between reactive rejuvenators and aged SMB can be occurred. The rejuvenation of aged SMB with MDI or BUDGE abides by the addition reaction mechanism or condensation reaction mechanism. (C) 2017 Elsevier Ltd. All rights reserved.

Facile synthesis of sludge-based mesoporous carbon with flocculants: Effect of template on the synthetic behavior and improved phenol capture

Based on the self-assembly of materials and pyrolysis technology, the template-like method was developed to construct sewage sludge-based mesoporous carbons (SSMCs) by employing sewage sludge as precursor of carbon source, and three different flocculants including cationic polyacrylamide, anionic polyacrylamide and chitosan as template. During the preparation, the flocculant played roles of nucleation, pore formation and surface group modification. Different types of templates have similar self-assembly behavior with sludge particles and endow various properties of SSMCs. The appropriate template concentration strengthens the adsorption bridging effect between template and sludge, thereby promoting the more stable assemblies among precursors. Potential physicochemical changes during thermal evolution are recorded to reveal its preparation mechanism from the aspects of mass loss, variation of functional groups and component change, showing that obvious difference in thermal stability between sludge and flocculant lays a foundation for the mesoporous regeneration of SSMCs. Simultaneous improvement of surface acidic-alkaline group content, mesoporous structure and adsorption performance can be achieved by template-like method. Compared with other SSMCs, product prepared from anionic polyacrylamide displayed higher affinity to phenol due to its higher abundant amide group and pi-pi interactions. This work provides new insight into the development of utilization of excess sludge in sewage treatment plant. (C) 2020 Elsevier Ltd. All rights reserved.

Improved spinnability of PA 6 solutions using AC electrospinning

The experiment addressed the alternating current (AC) electrospinning of polyamide 6 (PA 6) solutions composed of organic acids, which are commonly employed in direct current (DC) electrospinning systems. Initial testing revealed that it is not possible to AC spin ordinary PA 6 solutions so as to provide a product that can be used in subsequent material experiments. The solutions were enriched with oxoacids, which led to the improvement of the spinning process. The solutions were tested by means of both a viscometer and conductivity meter. The layers so produced were scanned using a SEM microscope. Each of the materials was analyzed for the purpose of the provision of statistical data. (C) 2020 Elsevier B.V. All rights reserved.

Transferrin conjugates of antitubercular drug isoniazid: Synthesis and in vitro efficacy

Tuberculosis (TB) caused by Mycobacterium tuberculosis (Mtb) has become the world’s leading killer disease due to a single infectious agent which survives in the host macrophage for the indefinite period. Hence, it is necessary to enhance the efficacy of the clinically existing antitubercular agents or to discover new anti antitubercular agents. Here, we report the synthesis, characterization and antimycobacterial evaluation of protein-drug conjugates. A carrier protein, Transferrin (Tf) was covalently conjugated to isoniazid (INH) utilizing hydrazone and amide linkers. The purity of the reactions was confirmed by SDS-PAGE while conjugation was confirmed by UV-visible spectrophotometry, MALDI-TOF analysis, and FFIR spectrophotometry. The in vitro antitubercular assay result showed that the inhibitory activity of the parent drug was conserved in both the conjugates. The conjugates were effective against intracellular Mtb H37Rv and were devoid of cytotoxic effect at therapeutic concentration. (C) 2019 Elsevier Masson SAS. All rights reserved.
