How Much Does a Scanning Electron Microscope (SEM) Cost?

A scanning electron microscope (SEM) is a powerful scientific instrument used for high-resolution imaging and surface elemental analysis. They work by scanning a focused beam of electrons across the sample’s surface and detecting the resulting signals to create detailed images. SEMs provide value in a wide range of applications including materials science, biology, nanotechnology, forensics, […]

How is Event-driven Detection Changing 4D-STEM?

Four-dimensional scanning transmission electron microscopy (4D-STEM) can yield a variety of atomically resolved measurements simultaneously, making it a widely used tool for both materials and life science applications [1]. In 4D-STEM, a sub-atomic focused electron beam is scanned across a thin sample while the full two-dimensional convergent beam diffraction pattern is collected at every probe position. Each probe position contained within a 2D raster array, therefore, correlates to a 2D image in reciprocal space, hence the name 4D-STEM.

Why Measure Impedance on Every Channel in a Battery Cycler?

Electrochemical measurements are essential for understanding the characteristics of battery cells, which enables the development of batteries with longer cycle lives and more efficient charge and discharge mechanisms. The electrochemical tests used for analyzing battery capacity, performance, and lifetime are typically carried out using a battery cycler with multiple measurement channels to boost throughput. Battery cycler technologies use repetitions of charge and discharge cycles under controlled conditions to provide information about how the cells behave over time. Battery cycling protocols vary based on the desired output data, but experiments can include open circuit potential (OCP), cyclic voltammetry (CV), chronopotentiometry (CP), and additional, more complex methods such as Electrochemical Impedance Spectroscopy (EIS).

Visualizing Skin Tissue Morphology with Scanning Electron Microscopy

The skin is the ultimate barrier to the human body, protecting it from mechanical damage, radiation, extreme temperatures, and pathogens. The skin consists of three layers: the epidermis (outer layer), dermis (middle), and hypodermis (inner layer). Each layer serves a distinct purpose. The epidermis provides the primary barrier whereas the dermis and hypodermis contain hair follicles, sweat glands, connective tissue, and fat to provide mechanical strength and warmth to our bodies. During minor injuries, the skin can normally regenerate the damaged areas on its own. In cases of extensive injuries, such as through disease or burn wounds, the skin is unable to regenerate on its own which leads to scar tissue formation or in worst cases, chronic wounds that need medical attention.

The Air Water Interface and Sample Preparation for Cryo-EM

The air-water interface (AWI) is essentially the chaotic boundary where a solution meets the air. When protein molecules in solution contact the AWI, they tend to align themselves along the interface with the hydrophilic regions facing inward towards the water environment and the hydrophobic regions facing outwards towards the air environment. The AWI presents one […]
