Free software for electronic structure and materials modeling using DFT principles.
Quantum ESPRESSO is a free, open-source software package for electronic structure calculations and materials modeling, based on density functional theory (DFT). It is a powerful tool for predicting the properties of materials and molecules using first-principles calculations, which are based on the fundamental laws of quantum mechanics. Quantum ESPRESSO includes a suite of programs for performing calculations on periodic systems, such as crystals and molecules, as well as on isolated systems, such as atoms and clusters. It can be used to predict a wide range of properties, including electronic structure, phonon dispersion, and optical spectra. Quantum ESPRESSO is widely used in the fields of physics, chemistry, and materials science, and it is distributed under the GNU General Public License (GPL). It is available for a variety of platforms, including Windows, macOS, and Linux, and it can be downloaded from the Quantum ESPRESSO website.

Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.
We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.
We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.
With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.
Yes. Every verified supplier states which service partners cover the instrument, and we list that alongside the offer.
Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.
Two to six weeks, depending on refurbishment scope and whether calibration is included.
We ship to 38 countries. Crating and customs handling are quoted with the instrument.
Tell us what you need and a scientist finds it for you, usually within the hour.
