Design of Multilayer Cathodes with Graded Porosity and Their Impact on Lithium‐Ion Battery Performance

open access: yesEnergy Technology, EarlyView.
This study explores multilayer cathodes with gradient porosity and their impact on electrochemical performance. For direct comparison with conventional single‐layer electrodes, thickness, mass loading, and overall porosity were kept constant. Graded‐porosity electrodes reduce tortuosity, enhance rate capability, and improve cycling stability ...

Development of a Zebrafish Embryo‐Based Test System for Thyroid Hormone System Disruption: 3Rs in Ecotoxicological Research

open access: yesEnvironmental Toxicology and Chemistry, EarlyView.
Abstract There is increasing concern regarding pollutants disrupting the vertebrate thyroid hormone (TH) system, which is crucial for development. Thus, identification of TH system–disrupting chemicals (THSDCs) is an important requirement in the Organisation for Economic Co‐operation and Development (OECD) testing framework.

Low‐temperature soft electrochemical actuator based on hierarchically structured polypyrrole membranes for subzero operation

open access: yesFlexMat, EarlyView.
A soft electrochemical actuator using a hierarchically structured polypyrrole membrane with coral‐like hollow vesicles achieves stable performance at −24°C. The unique architecture ensures continuous conductivity and rapid ion diffusion, resulting in large strain, low energy consumption, and high coulombic efficiency under subzero conditions. This work

Catechol‐Containing Poly(2‐isopropyl‐2‐oxazoline): Synthesis and Thermoresponsive Behavior in Aqueous Salt Solutions

open access: yesMacromolecular Rapid Communications, EarlyView.
Polymers carrying catechol groups are interesting mussel‐inspired materials for wet adhesion applications or metal ion complexation for wastewater treatment. Here, catechol‐containing poly(2‐isopropyl‐2‐oxazoline)s were synthesized via microwave‐assisted cationic (co)polymerization and examined with regard to their thermoresponsive LCST behavior in ...

Dracorhodin perchlorate induces apoptosis in bladder cancer cells through Bcl-2, Bcl-XL, survivin down-regulation and caspase-3 activation

open access: yesBangladesh Journal of Pharmacology, 2013
Urinary bladder cancer is one of the most commonly diagnosed urological malignancies worldwide. Dracorhodin perchlorate, anthocyanin red pigment, has been recently shown to induce apoptotic cell death in several types of cancer cells.

The Electrochemical Oxidation of Organic Selenides and Selenoxides [PDF]

open access: yes, 1997
The electrochemical oxidation of alkyl and aryl selenides was investigated in acetonitrile. The oxidation of diphenyl selenide and di(4‐methylphenyl) selenide led primarily to the formation of their respective selenoxides, which were identified by ...
