Effect of Pre-passivation on the Corrosion Behavior of PH13-8Mo Stainless Steel in Industrial—Marine Atmospheric Environment

open access: yesFrontiers in Materials, 2019
The corrosion behavior and mechanism of PH13-8Mo stainless steel with and without nitric acid passivated film were studied through 5 years of outdoor exposure tests in industry-marine atmospheric environments in Qingdao, by means of morphological ...

Fluorocholesterols, in contrast to hydroxycholesterols, exhibit interfacial properties similar to cholesterol

open access: yesJournal of Lipid Research, 2000
We used an automated Langmuir-Pockels surface balance to characterize the air–water interfacial properties of cholesterol (CH) and its derivatives with hydrophilic OH and F substitutions at isologous sites on the sterol body or side chain.

Electrochemical Perspective on Hematite–Malonate Interactions

open access: yesColloids and Interfaces, 2021
Organic matter (OM) interactions with minerals are essential in OM preservation against decomposition in the environment. Here, by combining potentiometric and electrophoretic measurements, we probed the mode of coordination and the role of pH-dependent ...

Lipid monolayers: action of phospholipase A of Crotalus atrox and Naja naja venoms on phosphatidyl choline and phosphatidal choline

open access: yesJournal of Lipid Research, 1966
The activity of phospholipase A on phosphatidyl choline and phosphatidal choline spread as monolayers on phosphate buffers containing snake venom (Crotalus atrox or Naja naja) was studied by measuring the fall of surface potential as a function of time ...

Analysis of the impact of handling and culture on the expansion and functionality of NK cells

open access: yesFrontiers in Immunology, 2023
Natural killer (NK) cells are lymphocytes of the innate immune system that play a key role in the elimination of tumor and virus-infected cells. Unlike T cells, NK cell activation is governed by their direct interaction with target cells via the ...

Surface potential-determined performance of Ti- and Zr-containing MXenes as anode materials of sodium ion batteries [PDF]

open access: yes, 2022
Sodium ion batteries have attracted increasing attention due to their low cost and abundant reserves of sodium, but their ideal anode materials still need to be explored.

High-Bandwidth Multiparametric Kelvin Probe Force Microscopy With Polymer Microcantilevers

open access: yesIEEE Access, 2019
Simultaneous and rapid measurement of the surface potential (SP) and nanomechanical properties (NMPs) of materials plays an important role in the study of, for example, piezoelectric materials and multi-component composites.

Surface-Potential-Based Compact Modeling of p-GaN Gate HEMTs

open access: yesMicromachines, 2021
We propose a surface potential (SP)-based compact model of p-GaN gate high electron mobility transistors (HEMTs) which solves the Poisson equation. The model includes all possible charges in the GaN channel layer, including the unintended Mg doping ...
