Contributions of Ti-xTa cold spray composite interface to in-vitro cell growth

Smart Materials in Manufacturing, 2023
Surface charge of biomaterials is one of the most influential parameters on regulating the complex processes of cell responses in tissue engineering. This study explores the contributions of xTa (x ​= ​5; 10; 30 in wt%) interface with the Ti as matrix on

Decay of Electric Charge on Corona Charged Polyethylene

, 2007
In this paper, the surface potential decay of corona-charged low density polyethylene (LDPE) films has been investigated. It has been found that for the same sample thickness the faster decay occurs in the sample with a higher charging voltage.

Photoelectrochemical Imaging System for the Mapping of Cell Surface Charges [PDF]

Analytical Chemistry, 2019
The surface charge of cells affects cell signaling, cell metabolic processes, adherence to surfaces, and cell proliferation. Our understanding of the role of membrane charges is limited due to the inability to observe changes without interfering, chemically or physically, with the cell or its membrane.

A new model for surface potential decay of corona-charged polymers [PDF]

, 2010
Surface potential measurement provides a useful tool to gauge the electrical properties of materials. It has been observed that the potential of a sample with an initial high surface potential decays faster than that with an initial lower surface ...

Investigation and electrochemical analysis of SEI layer formation in natural graphite anode formation process in lithium-ion battery

e-Prime: Advances in Electrical Engineering, Electronics and Energy, 2023
The solid electrolyte interface (SEI) layer is a surface film formed by the decomposition of the electrolyte in a lithium-ion battery on the anode surface. A proper understanding of the SEI layer formation process in graphite anodes can provide a broader

Positively charged polymers modulate the fate of human mesenchymal stromal cells via ephrinB2/EphB4 signaling

Stem Cell Research, 2016
Understanding the mechanisms by which mesenchymal stromal cells (MSCs) interact with the physical properties (e.g. topography, charge, ζ-potential, and contact angle) of polymeric surfaces is essential to design new biomaterials capable of regulating ...

Debye-Hückel Free Energy of an Electric Double Layer with Discrete Charges Located at a Dielectric Interface

Membranes, 2021
Poisson–Boltzmann theory provides an established framework to calculate properties and free energies of an electric double layer, especially for simple geometries and interfaces that carry continuous charge densities. At sufficiently small length scales,

Role of the cell-wall structure in the retention of bacteria by microfiltration membranes [PDF]

, 2009
This experimental study investigates the retention of bacteria by porous membranes. The transfer of bacteria larger than the nominal pore size of microfiltration track-etched membranes has been studied for several kinds of bacterial strains.
