A catalyst ink is a formulated suspension or dispersion containing catalytic material and a liquid medium, often with ion-conducting polymer, binder, or other additives. It is applied to a substrate to create a catalyst layer for electrochemical devices and research electrodes. Ink formulation strongly affects deposition, drying, microstructure, adhesion, and ultimately the measured electrode response.
sprayed porous titanium gas diffusion layer PEM electrolyzer sprayed porous titanium gas diffusion layer PEM electrolyzer I. Product Overview Ultrasonic spraying of porous titanium gas diffusion layers is a core functional component of proton exchange membrane (PEM) electrolyzers. Primarily applied to the anode side, it plays crucial roles in gas diffusion, mass transport, conductive connections, and structural support. In PEM water electrolysis for hydrogen production, the mass transfer [...]
Stent Coating Systems: Managing Strut Coverage, Bridging, and Expansion A coating system for medical instrument manufacturing faces a demanding geometry when the substrate is a stent. Narrow struts, junctions, openings, and curved surfaces can receive different amounts of material during a single pass. The coating must also tolerate relevant downstream handling. Stent coating development therefore requires a connection between deposition conditions, local morphology, and integrity after representative crimping [...]
Faraday's law connects the amount of chemical change at an electrode with the total electric charge passed through an electrochemical system. It is used to estimate deposited mass, gas production, reactant conversion, and current efficiency. In research and process development, it helps connect electrical operating conditions to expected material production.
Drug-Eluting Balloon Coating: Controlling Deposition, Morphology, and Handling A coating system for medical instrument production must account for what happens after spraying. Drug-eluting balloon development makes this especially clear: coating distribution, surface morphology, and handling can influence how the layer behaves during subsequent processing. A visually even film is only one development observation. Manufacturers need a formulation-specific evaluation connecting deposited loading, balloon geometry, drying, folding, and the intended [...]
The Nernst equation relates an electrode's equilibrium potential to the standard potential and the activities or concentrations of the chemical species involved. It explains why measured electrochemical potential changes with concentration, temperature, and reaction composition. For laboratory researchers, it provides a bridge between thermodynamics and the conditions present in a real electrochemical cell.
