Electroactive Ionic Polymer of Intrinsic Microporosity for High-Performance Capacitive Energy Storage.

Here, an ionic polymer of intrinsic microporosity (PIM) as a high-functioning supercapacitor electrode without the need for conductive additives or binders is reported. The performance of this material is directly related to its large accessible surface area. By comparing electrochemical performance between a porous viologen PIM and a nonporous viologen polymer, it is revealed that the high energy and power density are both due to the ability of ions to rapidly access the ionic PIM.

Evaluation of the Thermal, Chemical, Mechanical, and Microbial Stability of New Nanohybrids Based on Carboxymethyl-Scleroglucan and Silica Nanoparticles for EOR Applications.

Scleroglucan (SG) is resistant to harsh reservoir conditions such as high temperature, high shear stresses, and the presence of chemical substances. However, it is susceptible to biological degradation because bacteria use SG as a source of energy and carbon. All degradation effects lead to viscosity loss of the SG solutions, affecting their performance as an enhanced oil recovery (EOR) polymer.

Post-Intensive Care Syndrome Among Survivors in a Safety Net Hospital in South Bronx: A Comparison of Patients With and Without Coronavirus Disease 2019.

Comparison of post-intensive care syndrome between critically ill survivors with or without coronavirus disease 2019 (CovP and CovN, respectively) showed that fewer CovP were able to return to work full time at >1 year and none at <1 year after discharge and that the majority of CovP survivors were able to work part time during both evaluation periods compared to CovN.
