Oak Ridge National Laboratory: Quantum computing enables simulations to unravel mysteries of magnetic materials

A multi-institutional team became the first to generate accurate results from materials science simulations on a quantum computer that can be verified with neutron scattering experiments and other practical techniques. Researchers from the Department of Energy’s Oak Ridge National Laboratory; the University of Tennessee, Knoxville; Purdue University and D-Wave Systems harnessed the power of quantum annealing, a form of quantum computing, by embedding an existing model into a quantum computer.

3D Systems: 3D Systems Announces Breakthrough in Bioprinting Technology and Expansion of Regenerative Medicine Initiative

ROCK HILL, South Carolina, January 27, 2021 – 3D Systems (NYSE:DDD) today announced its decision to significantly expand its development efforts focused on regenerative medicine and bioprinting solutions. This decision was driven by the tremendous progress made in collaboration with United Therapeutics Corporation (NASDAQ:UTHR) and its organ manufacturing and transplantation-focused subsidiary, Lung Biotechnology PBC, on the development of 3D printing systems for solid-organ scaffolds. Leveraging this work as well as accomplishments with additional partners, 3D Systems intends to invest, further develop, and commercialize solutions for the diverse application opportunities in regenerative medicine, including the development of non-solid organ applications requiring biologically sustainable vasculature.

Berkeley Lab: A New Way to Measure Record-Setting Electron Beams

Physicists at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) are figuring out new ways to accelerate electrons to record-high energies over record-short distances with a technique that uses laser pulses and exotic matter known as a plasma. But measuring the properties of the high-energy electron beams produced in laser-plasma acceleration experiments has proven challenging, as the high-intensity laser must be diverted without disrupting the electron beam.

Oak Ridge National Laboratory: Compelling evidence of neutrino process opens physics possibilities

The COHERENT particle physics experiment at the Department of Energy’s Oak Ridge National Laboratory has firmly established the existence of a new kind of neutrino interaction. Because neutrinos are electrically neutral and interact only weakly with matter, the quest to observe this interaction drove advances in detector technology and has added new information to theories aiming to explain mysteries of the cosmos.

Vacuum Technology Primer

Since 2000 Vacuum Technology & Coating Magazine has been the industry's leading source for the latest articles, news, and product and service information. Below we describe some of the terms that you will find in a typical issue of VT&C.

Vacuum Coating (Vacuum Deposition and Thin Film Deposition) is the process of depositing a film or other material atom by atom or molecule by molecule onto a surface in a low pressure environment or vacuum.

Physical Vapor Deposition or PVD refers to vacuum deposition methods which involve the material (which is being deposited) going from a condensed phase to a vapor phase and then to a thin film condensed phase. Sputtering and evaporation are common PVD processes.

Sputtering refers to a type of process used to deposit thin films and employs a plasma to bombard and eject atoms from a target source.

Evaporation refers to the heated source material being evaporated in a vacuum. Vacuum allows vapor particles to travel directly to the target object, where they condense back to a solid state. (called a Deposition Source) refers to a type of process used to deposit thin films and employs a plasma to bombard and eject atoms from the target source (called a Deposition Source).

Vacuum Hardware refers to the types of hardware and components that are used in the vacuum process. There are many types of hardware used in this process, some examples are flanges, fittings, seals, valves, and chambers.

Thin Film Metrology involves determining the optimal thickness, composition and/or condition of a coating through various techniques and mathematical calculations.

Gas Analytical Systems are used in the analysis of residual gases within a low pressure environment or vacuum.

Vacuum Pumps are devices that remove gas atoms and molecules for the purpose of leaving behind a partial vacuum. Some examples of types of vacuum pumps are rotary vane pumps, diaphragm pumps, and scroll pumps.

Every issue of VT&C includes a product showcase focused on a specific topic relevant to Vacuum Processing, please see our editorial calendar which lists the topic for each issue.
