How Cryo-EM Differs from TEM

Cryo-electron microscopy (cryo-em) and transmission electron microscopy (TEM) share many similarities, but their main difference is in sample prep.

Choosing the right scanning electron microscope for your laboratory

This article introduces the imaging technique scanning electron microscopy (SEM) and gives readers guidance on the criteria to consider when choosing the right type of SEM instrument.

Suiting Up with NanoSuit for Imaging in the SEM

FAU Owls Lab uses a unique biofilm for imaging microorganisms in the NeoScope Tabletop Scanning Electron Microscope

Carbon Nanotubes imaged by TEM (L) and SEM (R)

Scanning Electron Microscopes Vs Transmission Electron Microscopes

Two of the most popular electron microscopy methods make use of scanning electron microscopes (SEM) and transmission electron microscopes (TEM).

A New (Faster) Method for Pesticide Analysis: LPGC and Short Collision Cell Technology

Dramatically reduce analysis time of GC-MS/MS pesticide measurement by combining the separation efficiency and decreased elution time of an LPGC column with the enhanced SRM switching speed of the short collision cell of JEOL’s JMS-TQ4000GC.

Discoveries in Disease Diagnostics: Exploring the Ear Canal with GC x GC-MS

Read more to learn how two-dimensional GC mass spectrometry (GC × GC–MS) can be applied for the characterization of the chemical components of earwax using non-polar (primary) and mid-polar (secondary) columns.

Using Tabletop Scanning Electron Microscopes for AM Quality Control

Tabletop Scanning Electron Microscopes are powerful tools for failure analysis, quality control and materials characterization in additive manufacturing.

Designing Better Batteries Through Innovative Microscopy Characterization

Lithium-ion batteries were commercially introduced in 1991, presenting new analytical challenges in the quest to improve the quality, safety, and lifespan of this fastest-growing battery chemistry. The basic structure of Lithium-ion batteries (LIB) contains as many as 10 different thin films that are synthesized to form at least that many solid−solid interfaces. These interfaces consist of thin layers of cathode material, insulating barriers, anode materials, metal current collectors, and the electrolyte. These various components are in the form of powders, sheets, and fluids and require an assessment before and after assembly and after repeated charge/discharge operations.
