KherveDB Library - XPS Database Application

A comprehensive X-ray Photoelectron Spectroscopy (XPS) binding energy database application that provides access to the NIST XPS database archived in 2019.

Application Screenshot

Overview

The KherveDB Library is a desktop application that preserves and provides easy access to the NIST X-ray Photoelectron Spectroscopy binding energy database. This database was recorded in 2019 before it was shut down during the Trump administration and serves as an invaluable resource for scientists and researchers in materials science, chemistry, and physics fields.
