Melting and Crystallisation of Phase Change Materials (PCM) by Microcalorimetry

Phase change materials (PCMs) are substances that can absorb or release large amounts of latent heat. This happens when their physical state changes, generally, either from solid to liquid or vice versa. Microcalorimetry is a technique for measuring the energy absorbed or released during a phase change process thus enabling the amount of energy to […]

An Introduction to Ion Beam Milling (IBM)

SEMPrep 2 SC-2100

SciMed Education An Introduction to Ion Beam Milling (IBM) Ion beam milling produces a sample which is thin, smooth, and free of surface debris. The technique is suitable whenever a high-resolution cross-sectional image is desired. Polymerics Ceramics Metals Geological specimens What are the components of an Ion Beam Mill? A basic Ion Beam Mill system […]

Electroless Nickel Plating

Electroless nickel plating (ENP) is a technique for protecting materials from corrosion, wear and abrasion. It is widely used across a range of industries, including: Engineering Construction Aerospace Electronics A crucial part of the ENP process is the accurate measurement of thickness and composition. The perfect technique for this is x-ray fluorescence (XRF). What is […]

An introduction to viscometers

Viscometers are instruments that measure the fluid flow and viscosity of liquids. The viscosity of a liquid can affect its performance, whether this is pumping or piping it, or how it performs for dipping and coating. Measuring viscosity, therefore, applies to a wide range of materials, including: Oil Plastics Paints Coatings Adhesives Wax Asphalt Measuring […]

What are 10 different petroleum products that are made from crude oil?

SciMed Education What are 10 different petroleum products that are made from crude oil? Crude oil makes much of the modern world possible. It is a complex mixture of hydrocarbons, formed over millions of years from the remains of plants and animals. In other words, it’s literally a fossil fuel, existing in underground reservoirs and […]

What is a Hydrogen Generator?

SciMed Education What is a Hydrogen Generator? What is a Hydrogen Generator? A Hydrogen generator is a machine that is used to produce hydrogen from water, using a process called electrolysis. If the supply pressure of hydrogen from the generator is high enough, it can eliminate the need for hydrogen cylinders by providing a safer […]

What is AOX analysis?

Flash point testing is a procedure designed to determine whether a sampled mixture of vapour and air is flammable. It can also determine the temperature at which flammability occurs in a sample. The lowest temperature at which its vapours ignite from an ignition source is the flash point of a material. Flash point analysis is […]

what is total organic carbon

SciMed Education What is total organic carbon? What is Total Organic Carbon? All organic molecules have carbon in them: Total organic carbon (TOC) is the measure of the concentration of organic carbon in a substance and is considered to be the best indicator of contamination, or purity, of a substance. It is also possible to […]

What is X-Ray Fluorescence (XRF)

X-ray fluorescence, or XRF, is a technique for analysing the different elements of a broad range of materials. They include metals, plastics and minerals. The aim of this piece explain what XRF is, how and why people use it, its advantages and disadvantages, the equipment involved, and look at the kind of data it produces. […]
