Abstract

A cage-like MOF has demonstrated tremendous potential in gas selective adsorption and CO2 catalysis due to its distinctive structural features. Accordingly, a novel cage-like MOF 1 was synthesized using the biphenyl tricarboxylic acid ligand, (1,1′-biphenyl)-2,4,6-tricarboxylic acid (H3L), and Zn(II) via a solvothermal reaction. 1 exhibited a porous three-dimensional framework formed by interconnected dodecahedron (5.2 Å) and octahedron (4.7 Å) cages, which was based on an interesting 13-connected fcu topology. Significantly, 1a has excellent adsorption properties for C2H2 and CO2 and selective separation performance for C2H2/CO2, C2H2/CH4, and CO2/CH4. Moreover, under the action of the Lewis acid sites, 1a also shows highly efficient and recyclable catalytic properties for the reaction of CO2 with various epoxides. [ABSTRACT FROM AUTHOR]

45. Visible Light-Accelerated Palladium-Catalyzed Thiocarbonylation Using Oxalic Acid Monothioester with Aryl/Alkenyl Sulfonium Salts

Author

Hu, Guo-Qin, Zhang, Wen-Yan, Liu, Yong-Xin, Liu, Jing-Hui, and Zhao, Bin

Abstract

Herein, we present a decarboxylative thiocarbonylation of aryl and alkenyl sulfonium salts with oxalic acid monothioethers (OAMs), which can be achieved by visible light-accelerated palladium catalysis. Sulfonium salts are widely available, and OAM is an easily accessible and stored reagent; this mild reaction method can also be used for the synthesis of different types of thioester compounds. The reaction represents a new application of visible light-accelerated palladium catalysis in catalytic decarboxylative cross-couplings.

47. Efficient C2H2-selective separation in a microporous Zn(II)-based metal–organic framework via the dual-ligand strategy.

Abstract

Implementing the dual-ligand strategy, a microporous Zn-based MOF 1 with nitro and amino groups was effectively produced. The activated interconnected pores of 1 exhibited high C2H2 uptake capacity and preferential adsorption behaviour for C2H2 over CO2, as identified by the experiments and simulations. This work provides a new approach for designing and synthesizing the MOFs with desired structures and properties by optimizing their pore environment via the dual-ligand strategy.

Abstract

Aim: Postoperative pain has adverse effects on children with urological problems, including sleep disturbances, incision dehiscence, bleeding and delayed recovery. Accurate parental assessment of children's behaviours and responses could help to manage postoperative pain. We aimed to implement evidence‐based practice for parental involvement in a urology ward, to increase parents' participation in children's postoperative pain management. Design: The project was conducted in a paediatric urology ward using the framework and methods of the Fudan University Evidence‐Based Nursing Center's Evidence‐based Continuous Quality Improvement Model. Methods: Fifteen audit criteria were used to represent best practice recommendations for parental involvement in postoperative pain management. A pre‐implementation audit was conducted with 211 randomly sampled children and parents. Obstacles, promoting factors and key strategies were analysed, and evidence‐based interventions implemented to improve compliance. A follow‐up audit using the same audit criteria was conducted with 202 children and parents to assess the effect of targeted strategies on compliance with best practice. The SQUIRE guidelines were followed. Results: At the baseline audit, compliance with the evidence‐based criteria was 0%–71.5%; only five audit criteria achieved a compliance rate > 60%. After best practice implementation, the follow‐up audit showed compliance improvements for all criteria; compliance for three criteria improved to 100%. Patient or Public Contribution: This best practice implementation project improved parents' participation in children's postoperative pain management. The findings demonstrate how audits can promote best practice in postoperative pain management for children. Additional studies will be conducted to address children's postoperative life quality based on best practice. [ABSTRACT FROM AUTHOR]
