Montana Instruments Introduces CryoCore™ for High-Throughput Electrical and Optical Materials Characterization

This April, Montana Instruments Corporation, a manufacturer of high precision, fully automated closed-cycle optical cryostats, introduced CryoCore™, a new streamlined cryogenic platform built for high-throughput electrical and optical materials characterization. Using advancements in thermal and low vibration design, the cryostat is a low vibration, cryogen-free system that allows users to...

New Combination of Materials Provides Progress Toward Quantum Computing

In research published June 14 in Nature Communications, engineers from Rensselaer Polytechnic Institute demonstrated how, when semiconductor materials known as the transition metal dichalcogenides (TMDCs) materials they make are stacked in a particular geometry, the interaction that occurs between particles gives researchers more control over the devices’ properties. Specifically, the...

Refrigeration Breakthrough Takes Chinese Quantum Science Near Absolute Zero

China has achieved a breakthrough in self-developed refrigeration equipment – a high-end scientific device that can provide an environment of near absolute zero without using liquid helium. The device lasts longer and is more convenient to use and maintain, compared with traditional cooling machines that use cryogens. The device was...

Helium II

Helium II (He II) refers to the second liquid phase of the most abundant helium isotope (4He). Helium II is also referred to as superfluid helium. Helium II occurs once the temperature of the liquid helium drops below 2.17K. The phase transition between the first liquid phase of Helium (referred...

Bose-Einstein Condensate

A Bose-Einstein condensate, first proposed in 1925 by Albert Einstein based on work done by Satyendra Nath Bose (the same Bose from whom the term boson is derived), is a super-cold state of matter in which almost all of the individual atoms have “condensed” down to the lowest possible quantum...

Cold Technology for Pest Control

While it does not reach temperatures cold enough to be called cryogenic, carbon dioxide snow is at the heart of a new way of dealing with unwanted pests. It utilizes a quick freezing process that takes advantage of the properties of carbon dioxide snow and has a number of benefits...
