In materials science, a surface interface refers to the boundary region between air (or a vacuum) and physical media. The atomic composition and topography of a solid’s surface monolayer can determine many of the chemical-mechanical characteristics of the bulk...
A Brief History of Lithium-Ion Battery Development
For many years, the only suitable battery for portable equipment, such as mobile computing and wireless communications, was nickel-cadmium. Pioneer work on the lithium battery began in 1912. However, it wasn’t until the 1970s when the first non-rechargeable lithium batteries became commercially accessible.
Fermentation Process Monitoring with Off-Gas and Dissolved Gas Analysis
Fermenters are used to accelerate the metabolic reactions within heterogeneous systems and promote population growth of desirable fungi and bacterial cells. This is typically conducted by introducing enzymes or other microorganisms to organic substrates in a hermetically sealed container. The medium is continuously mixed and either aerated (aerobic fermentation) or starved of oxygen (anaerobic fermentation). Numerous additional parameters must be controlled during process monitoring, including the gaseous composition of the headspace; net temperature within the bioreactor; pH level of the system; pressure levels; and more.
Electrocatalyst Studies: Enabling Next-Gen Fuel Cells
What is a Fuel Cell? Fuel cells generate electricity through an electrochemical reaction rather than combustion. Inside a fuel cell, hydrogen and oxygen are combined to generate heat, water and electricity. They represent a clean, efficient, dependable, and quiet...
Key Objectives in Modern Fuel Cell Studies
Fuel cells use the chemical energy of hydrogen or an alternative fuel to cleanly and efficiently produce electricity. Using hydrogen as the fuel only produces water, heat, and electricity. Hydrogen (the fuel) is supplied continuously, unlike in a battery, and a dynamic equilibrium is maintained.
Solar Cell Thin Film Analyzers from Hiden Analytical
Solar cell thin film analyzers are used to facilitate research and development (R&D) into novel photovoltaic architectures by monitoring the processing conditions for epitaxial deposition of photovoltaic materials. These growth methods cover a range of advanced...
Plasma Engineering: What is Electron Cyclotron Resonance?
Electron Cyclotron Resonance (ECR) is an advanced excitation method used in plasma engineering. The underlying principle of ECR is explained by Lorentz force; a combination of both electric and magnetic forces induced by applied magnetic fields.
Hydrogen in Steel Measurements with the UHV-TPD Workstation
Determination of hydrogen bound in steel is a vital factor in developing new steel types for ever more demanding applications. Temperature Programmed Desorption (TPD), also known as Thermal Desorption Spectrometry (TDS) or Thermal Desorption Analysis (TDA) is a...
Gas Analyzers for Fuel Cell Research
Electrochemical fuel cells are envisaged as a potential successor technology to combustion engines in the automotive sector. Although studies have considered numerous gaseous elements as the fuel source for electrochemical stacks, hydrogen (H2) remains the primary...
The History of Gas Analysis in Electrochemistry
Electrochemistry is concerned with the range of oxidation-reduction (redox) reactions that cause electrons to transfer between the molecules of reactants. It is the study of the relationship between electricity and an identifiable chemical change, which was first...
