Low-cost electron detector for scanning electron microscope

HardwareX, 2023
Electron microscopy is an indispensable tool for the characterization of (nano) materials. Electron microscopes are typically very expensive and their internal operation is often shielded from the user.

Determination of Sapphire Off‐Cut and Its Influence on the Morphology and Local Defect Distribution in Epitaxially Laterally Overgrown AlN for Optically Pumped UVC Lasers [PDF]

, 2019
Herein, a systematic study of the morphology and local defect distribution in epitaxially laterally overgrown (ELO) AlN on c‐plane sapphire substrates with different off‐cut angles ranging from 0.08° to 0.23° is presented. Precise measurements of the off‐

3-D Ultrastructure of O. tauri: Electron Cryotomography of an Entire Eukaryotic Cell [PDF]

, 2007
The hallmark of eukaryotic cells is their segregation of key biological functions into discrete, membrane-bound organelles. Creating accurate models of their ultrastructural complexity has been difficult in part because of the limited resolution of light

easySTORM: a robust, lower-cost approach to localisation and TIRF microscopy [PDF]

, 2016
TIRF and STORM microscopy are super-resolving fluorescence imaging modalities for which current implementations on standard microscopes can present significant complexity and cost. We present a straightforward and low-cost approach to implement STORM and

Intermodulation electrostatic force microscopy for imaging surface photo-voltage

, 2014
We demonstrate an alternative to Kelvin Probe Force Microscopy for imaging surface potential. The open-loop, single-pass technique applies a low-frequency AC voltage to the atomic force microscopy tip while driving the cantilever near its resonance ...

Open, reproducible hardware for microscopy

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences
Reproducibility and transparency have always been central tenets of good experimental science. In recent years, these have led to ‘open science’ practices, including openly archived data, openly licensed code and open access to publications describing key results [1–3].
