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.

Thermally stable, solution processable and redox active new poly(amide-imide)s: synthesis and characterization

A series of new poly(amide-imide)s was prepared by polycondensation of our already reported diamine, N,N’-[((propane-2,2-diylbis(4,1-phenylene) bis(oxy))bis(4,1-phenylene)]bis(4-aminobenzamide) (BDM) containing flexible ether and amide linkages with different aromatic dianhydrides via simple two-step method. The synthesized poly(amide-imide)s were characterized by FTIR spectroscopy and elemental analysis. These poly(amide-imide)s demonstrated nice solubility in most of the organic solvents at ambient temperature and upon heating. They also revealed great thermal stability and showed glass transition temperatures (Tgs) exceeding 150 degrees C in addition to the temperature of 10% weight loss (T-10) that fluctuated from 460 to 522 degrees C having more than 59% residual yield at 800 degrees C in nitrogen atmosphere indicating their flame retardant characteristics. Furthermore, they also showed interesting photoluminescent properties with blue green solution emission properties, redox activity, and lower onset oxidation potentials with appreciably shallow HOMO levels.

Recent progress of fillers in mixed matrix membranes for CO2 separation: A review

Among various CO2-mitigation technologies, membrane-based technology has offered a more energy efficient and eco-friendly process for CO2 separation from large emission sources, in order to reduce CO2 emission level into atmosphere. In general, polymeric and inorganic membranes have been used in gas separation processes, but each has its own pros and cons. Currently, membrane research has addressed the trade-off limitations of membranes in different ways through fabrication of new type of mixed matrix membranes (MMMs) by incorporation of inorganic particles as fillers into polymer matrices. The performance of MMMs depends on textural properties of fillers, molecular sieving effect and membrane-penetrant interactions. The main challenges in the fabrication of MMMs is selection of fillers, which controls the gas separation characteristics of membranes. In this review, the influences of fillers like zeolite, carbon, and metal organic framework in MMMs fabrication and their CO2 permeability and CO2/CH4 and CO2/N-2 selectivity were compiled from recent reports. Further, a new protocol is introduced for screening of fillers, which will helps to development of new fillers as well as for fabrication of new MMMs with high CO2 separation capacity.

Structure-property-reactivity studies on dithiaphospholes

The reaction of either toluene-3,4-dithiol or benzene dithiol with phosphorus(iii) trihalides generates the corresponding benzo-fused 1,3,2-dithiaphospholes, RC6H3S2PX (R = Me (1), R = H (2); X = Cl, Br, I). The P-chloro-dithiaphospholes undergo: (a) halogen abstraction reactions with Lewis acids forming phosphenium cations; (b) substitution with LiHMDS base and; (c) reduction chemistry with sodium metal to generate the P-P sigma-bonded dimer, (RC6H3S2P)(2). Reduction catalysis of aldehydes with pinacolborane using dithiaphospholes is compared with their dioxaphosphole and diazaphosphole counterparts as pre-catalysts, revealing interesting differences in the reactivity of this series of compounds.

Rotationally Assisted Spin-State Inversion in Carbene-Metal-Amides Is an Artifact

High-level quantum chemical calculations, presented in this Letter, show that the unusual luminescence properties of the high-performance thermally activated delayed fluorescence emitter CMA1, observed recently by Di et al. [Science 2017, 356, 159-163], can be explained without resorting to the rotationally assisted spin-state inversion mechanism proposed by these authors. Multiconfiguration and relativistic effects lead to fast and efficient thermal equilibration of the excited singlet and triplet populations of this linear gold complex even for coplanar orientations of the ligands. The calculations predict S-1(sic)T-1, intersystem crossing outcompetes the submicrosecond fluorescence by 2 orders of magnitude, thus quenching prompt fluorescence. The significant time- and environment-dependent shifts of the CMA1 luminescence, observed in experiment, are attributed to effects of (hindered) solvent reorganization.

Effects of Amide-Based modifiers on surface activation and devulcanization of rubber

This paper examines the mechanisms of interaction between two modifiers in asphalt binder: an amide-based bio-modifier, and natural rubber vulcanized by sulfur crosslinks. The amide-rich bio-modifier surface-activates the rubber, cleaving the disulfide bonds and leading to partial surface devulcanization. Computational modeling and laboratory experiments were used to evaluate the devulcanization mechanism and its effects. Results show that non-covalent interaction between the -NH2 site of the bio-modifier and the S-S crosslink of the rubber is stronger than with the C-S part of the rubber, which can potentially induce partial devulcanization. This phenomenon is reflected in the empirical results: a reduction in viscosity, due to devulcanization; and an increased resistance to fatigue, due to improved interaction between rubber and bitumen. This study provides an in-depth understanding of the surface devulcanization mechanism of rubber, in addition to insights into the complex devulcanization process happening inside a bio-modified mixture of rubber and asphalt binder. The results of this study help expand the knowledge of bio-modifiers and present a new approach for devulcanization.

A dual inhibitor of FAAH and TRPV1 channels shows dose-dependent effect on depression-like behaviour in rats

Objective The cannabinoid receptor 1 (CB1) and transient receptor potential cation channel subfamily V member 1 (TRPV1) are proposed to mediate opposite behavioural responses. Their common denominator is the endocannabinoid ligand anandamide (AEA), which is believed to mediate antidepressant-like effect via CB1-R stimulation and depressive-like effect via TRPV1 activation. This is supposed to explain the bell-shaped dose-response curve for anandamide in preclinical models. Methods We investigated this assumption by administering the dual inhibitor of AEA hydrolysis and TRPV1 activation N-arachidonoyl-serotonin (AA-5HT) into the medial prefrontal cortex of rats. AA-5HT was given in three different doses (0.125, 0.250, 0.500 nmol/0.4 mu l/side) and rat behaviour was assessed in the forced swim test. Results Our results show significant antidepressant-like effect of AA-5HT (0.250 nmol) but no effects of low or high doses. The effect of 0.250 nmol AA-5HT was partially attenuated when coadministering the inverse CB1-agonist rimonabant (1.6 mu g). Conclusion A 0.250 nmol of AA-5HT administration into the medial prefrontal cortex induced a significant antidepressant-like effect that was partially attenuated by locally blocking CB1-receptor.

Pd(II)/Cu(II)-Catalyzed Regio- and Stereoselective Synthesis of (E)-3-Arylmethyleneisoindolin-1-ones Using Air as the Terminal Oxidant

Regio- and stereoselective synthesis of (E)-3-arylmethyleneisoindolin-1-ones via Pd(II)/Cu(II)-catalyzed one pot C-C/C-N bond forming sequence between amides and styrenes is reported. This method provides facile and rapid access to a diverse range of such compounds using readily available starting materials under mild aerobic conditions with good functional group tolerance and high selectivity and efficiency. Further elaboration of the products obtained from this process enabled very short and efficient syntheses of aristolactam and indoloisoquinolinone alkaloids.

Organoaluminum cations for carbonyl activation

In search of stable, yet reactive aluminum Lewis acids, we have isolated an organoaluminum cation, [(Me2NC6H4)(2)Al(C4H8O)(2)](+), coordinated with two labile tetrahydrofuran ligands. Its catalytic performance in aldehyde dimerization reveals turn-over frequencies reaching up to 6000 h(-1), exceeding that of the reported main group catalysts. The cation is further demonstrated to catalyze hydroelementation of ketones. Mechanistic investigations reveal that aldehyde dimerization and ketone hydrosilylation occur through carbonyl activation.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 617-45-8, you can contact me at any time and look forward to more communication. Category: amides-buliding-blocks.
