Spectroscopic Investigation of Polysulfide Redox Evolution in Catholyte Solutions for Potassium–Sulfur Batteries

open access: yesAdvanced Functional Materials, EarlyView.
Potassium–sulfur batteries are investigated using UV–vis spectroscopy to track the evolution of potassium polysulfide species at elevated temperature. The study reveals sulfur radical anions as key intermediates and shows how solvent composition and cell design influence polysulfide stability, redox behavior, and cycling performance, providing insights

Stimulation of renin secretion by potassium-channel activation with cromakalim

open access: yes, 1989
The cardiovascular and endocrine profile of cromakalim has been studied in 8 healthy men (age 25 +/- 2 years: means SEM) and its influence on renin release from cultured rat juxtaglomerular cells in vitro has also been examined.

A Small Conductance Calcium-Activated K+ Channel in C. elegans, KCNL-2, Plays a Role in the Regulation of the Rate of Egg-Laying [PDF]

open access: yes, 2013
In the nervous system of mice, small conductance calcium-activated potassium (SK) channels function to regulate neuronal excitability through the generation of a component of the medium afterhyperpolarization that follows action potentials.

Designed Lewis Acid–Base Passivation for High Performance Perovskite Solar Cells

open access: yesAdvanced Functional Materials, EarlyView.
ABSTRACT Silicon's high cost and long energy payback time remain major barriers to the global expansion of solar power. In contrast, metal–halide perovskites offer abundant, solution‐processable absorbers, and have achieved efficiencies of 25%–30%, positioning them as strong competitors to silicon.

Molecular mechanisms of the coupling of gating to voltage sensing in transmembrane proteins [PDF]

open access: yes, 2014
Voltage gated potassium ion (Kv) channels regulate action potentials of the nervous system by responding to changes in transmembrane voltage, enabling K+ transport across the membrane to restore cells to their resting potential.

Microfabricated Anisotropic Myobundles for the Scalable Production of Cardiac Tissue Grafts

open access: yesAdvanced Functional Materials, EarlyView.
Controlling the anisotropy of cardiac tissue remains an outstanding challenge in the field of cardiac tissue engineering. Here, we introduce an approach to generate anisotropic cardiac myobundles using cell‐adhesive, synthetic, electrospun fibers and stem cell‐derived cardiac fibroblasts.

Structure and function of potassium and calcium channels [PDF]

open access: yes, 2005
In this thesis, potassium channels human Kv2.1 and rat Kv2.1, along with calcium channels Ca, 1.2, Ca, 3.1, and chimeras have been studied. These channels were expressed in Xenopuso ocytesf or electrophysiological experiments using two electrode voltage

Immunolocalization of KATP channel subunits in mouse and rat cardiac myocytes and the coronary vasculature.

open access: yes, 2005
BACKGROUND: Electrophysiological data suggest that cardiac KATP channels consist of Kir6.2 and SUR2A subunits, but the distribution of these (and other KATP channel subunits) is poorly defined.

Unlocking Exceptional Strengthening in Aluminum Alloys via Interstitial Cottrell Atmosphere Formation

open access: yesAdvanced Functional Materials, EarlyView.
Cyclic unloading‐aging‐reloading micro‐tensile tests under various aging durations and temperatures, combined with comprehensive microstructural characterization reveal that the yield point phenomenon in Aluminum‐Carbon (Al‐C) thin films originates from Cottrell atmosphere formation.
