Oak Ridge National Laboratory: Buildings — Split-second leak detection

Oak Ridge National Laboratory researchers demonstrated that an electrochemical sensor paired with a transmitter not only detects propane leaks within seconds, but it can also send a signal to alert emergency services. Propane is an alternative refrigerant that has low global warming potential. However, because of its flammability risk, it is not widely used commercially in the United States. To mitigate concerns, researchers attached a transmitter to an off-the-shelf sensor and developed a computer program that monitors the signal, self-checking every few seconds.

Berkeley Lab: Bacteria for Blastoff: Using Microbes to Make Supercharged New Rocket Fuel

Converting petroleum into fuels involves crude chemistry first invented by humans in the 1800s. Meanwhile, bacteria have been producing carbon-based energy molecules for billions of years. Which do you think is better at the job? Well aware of the advantages biology has to offer, a group of biofuel experts led by Lawrence Berkeley National Laboratory (Berkeley Lab) took inspiration from an extraordinary antifungal molecule made by Streptomyces bacteria to develop a totally new type of fuel that has projected energy density greater than the most advanced heavy-duty fuels used today, including the rocket fuels used by NASA.

Berkeley Lab: Pushing the Boundaries of Moore’s Law: How Can Extreme UV Light Produce Tiny Microchips?

Advances in microelectronics – also known as microchips or chips – have enabled fast, powerful, compact smartphones and laptops – electronic devices that were once, long ago, the stuff of science fiction. Chips consist of miniaturized components called transistors – tiny silicon switches that process and store data as ones and zeroes, the binary language of computers. The more transistors a chip has, the faster it can process data. The most sophisticated chip today is about the size of a fingernail and consists of more than 100 billion transistors.

NIST: NIST Awards Funding to Strengthen Advanced Manufacturing for Critical and Emerging Technologies

GAITHERSBURG, Md. — The U.S. Department of Commerce’s National Institute of Standards and Technology (NIST) has awarded a total of $2.08 million to seven organizations in six states to develop manufacturing technology roadmaps to strengthen U.S. innovation and productivity across entire industry sectors. This is the second round of grants awarded to universities, industry and nonprofit organizations through NIST’s Advanced Manufacturing Technology Roadmap Program (MfgTech).

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.
