Volt-ampere characteristics of porcine retinal Müller cell intermediate filaments

open access: yesChemical Physics, 2020
Abstract In the current study we reported current-voltage (I/V) characteristics of Muller cell (MC) intermediate filaments (IFs) isolated from porcine retina. It was found that the measured I/V dependences demonstrate behavior of a semiconductor in contact with metal (Au) electrodes.

RELATIONSHIP OF THE VOLT-AMPERE CHARACTERISTICS OF SOLAR CELLS TO TEMPERATURE

open access: yes, 2022
Annotation: In this work, an equation was obtained that allows to explain the experimental results for the temperature dependence of the QE VAX prepared on the basis of semiconductors. By comparing the results obtained by calculating this equation with the experimental results, it was shown that the temperature change in the investigated range does not

FastCat: Autonomous Discovery of Multielement Layered Double Hydroxide Alloy Catalysts for Alkaline Oxygen Evolution Reaction

open access: yesAdvanced Intelligent Discovery, EarlyView.
A machine learning‐guided self‐driving laboratory screened over 500 nickel‐based layered double‐hydroxide catalysts for alkaline oxygen evolution. Out of the eight metals, the robot uncovered a quaternary Ni–Fe–Cr–Co catalysts requiring only 231 mV overpotential to reach 20 mA cm−2.
