Tang, Yuyin;Li, Su;Hu, Linyu;Sun, Xuetong;Zhang, Bei;Ji, Wenwen;Ma, Lijuan;Qian, Wenhui;Kang, An;Zhu, Dong research published 《 Hybrid Poly(AMPS-CS)-Au Microneedle Arrays to Enrich Metabolites from Skin for Early Disease Diagnosis》, the research content is summarized as follows. Recently, some metabolites in skin interstitial fluid (SIF) have become emerging rexsources for early disease diagnosis. However, their low level in SIF and difficulty to sampling are the biggest obstacle to further potential application. Here, a swellable microneedle array patch (MNAP) with high mech. strength is presented, and the rapid enrichment of pos. charged metabolites is achieved. The MNAP is fabricated by poly (chondroitin sulfate-acrylamido-2-methylpropane sulfonic acid)-gold nanoparticles (GNPs) composites via a micro-molding. The neg. charged copolymer hydrogel not only enrich pos. charged metabolites, but also provide swellable capacity. The in situ synthesis of GNPs in the process of copolymerization make the GNPs crosslink to the hydrogel, which further enhance the MNAP mech. strength and enrichment efficiency for pos. charged metabolites. By using the MNAP, around 5 mg SIF in 10 min from the high fat/cholecalciferol/methimazole-induced atherogenesis rat is extracted and 23 metabolites including 13 quaternary ammonium cationic compounds can be detected and quantified by using a LC-QTOF-MS. Dysregulated L-carnitine and choline metabolism are discovered a week earlier in the SIF than in the serum, achieving early diagnosis of the metabolism syndrome disease. This MNAP also helps users complete home sampling for early disease diagnosis and monitoring.

Tang, Hongying;Aili, David;Geng, Kang;Gao, Jian;Li, Qingfeng;Li, Nanwen research published 《 On the stability of imidazolium and benzimidazolium salts in phosphoric acid based fuel cell electrolytes》, the research content is summarized as follows. Polymers containing organic cations are considered as promising materials for phosphoric acid (PA) doped high temperature polymer electrolyte membranes (HT-PEMs) due to higher PA retention and wider operation temperature range. However, the thermal/acidic stability of the organic cations remains to be determined Herein, a series of model cations based on various (benz)imidazoliums are designed and prepared to assess the stability on mol. level under simulated operating conditions for HT-PEM fuel cell. NMR anal. indicates that C2, C4 and C5 substitutions show little effect on the stability while N1 and N2 substitutions show opposite effect. Among the N-functionalized derivatives, N, N-dimethyl (benz)imidazolium cations are fully stable while N-benzyl imidazoliums degraded severely due nucleophilic substitution with H₂PO₄^–. On this background, blend membranes based on fully methylated polybenzimidazole (PBI) are prepared, and the swelling is balanced by introducing pristine PBI. The proton conductivity of the PA doped blending membrane with IEC of 1.2 mmol g-1 reaches 165 mS cm^-1 and a peak power d. of 863 mW cm^-2 is demonstrated in H₂/O₂ fuel cell test. These results lay a solid foundation for designing and developing durable high-performance HT-PEMs and fuel cell devices for green energy conversion applications.

In recent years, forward osmosis (FO) has been attracting attention as a new energy-saving water treatment technol. In order to put the FO process to practical use, it is indispensable to develop the optimum DS and construct a low energy regeneration process. In this work, the author synthesized 6 kinds of ionic liquids with imidazolium-based cations for the purpose of developing ILs-type DS showing UCST-type phase transition at 30 to 50 °C. As a result of drawing a phase diagram for 11 types of ILs, including com. available ILs, [Im (1.0.5)] [BF4], [Im (1.1.5)] [BF4] and [Im (2.0.4)] [BF4] showed good phase transition characteristics. As a result of further evaluation of the osmotic pressure performance, [Im (2.0.4)] [BF4] demonstrated higher osmotic pressure than seawater as a driving force for forward osmosis and low osmotic resistance in post-treatment with an RO membrane. It was shown that [Im (2.0.4)] [BF4] can be applied as DS used for seawater desalination using the FO method.

Tailor, Sanita B.;Manzotti, Mattia;Smith, Gavin J.;Davis, Sean A.;Bedford, Robin B. research published 《 Cobalt-Catalyzed Coupling of Aryl Chlorides with Aryl Boron Esters Activated by Alkoxides》, the research content is summarized as follows. The cobalt-catalyzed Suzuki biaryl cross-coupling of aryl chloride substrates with aryl boron reagents, activated with more commonly used bases, remained a significant unmet challenge in the race to replace platinum group metal catalysts with Earth-abundant metal alternatives. This highly desirable process can be realized using alkoxide bases, provided the right counterion is employed, strict stoichiometric control of the base is maintained with respect to the aryl boron reagent, and the correct boron ester is selected. Potassium tert-butoxide works well, but any excess of the base first inhibits and then poisons the catalyst. Lithium tert-butoxide performs very poorly, while even catalytic amounts of lithium additives also poison the catalyst. Meanwhile, a neopentane diol-based boron ester is required for best performance. As well as delivering this sought-after transformation, a detailed mechanistic and computational investigations to probe the possible mechanism of the reaction has been discussed and explains the unexpected exptl. observations.
