Berkeley Lab: Sizing Up the Challenges in Extracting Lithium from Geothermal Brine

If you had a jar of marbles of many different colors but wanted only the green ones, how could you efficiently pick them out? What if it wasn’t marbles but a jar of glitter, and there was sand, glue, and mud mixed in? That begins to describe the complexity of the brine pumped out from beneath California’s Salton Sea as part of geothermal energy production.

Berkeley Lab: Turning Up the Heat: Thermal Energy Storage Could Play Major Role in Decarbonizing Buildings

Could a tank of ice or hot water be a battery? Yes! If a battery is a device for storing energy, then storing hot or cold water to power a building’s heating or air-conditioning system is a different type of energy storage. Known as thermal energy storage, the technology has been around for a long time but has often been overlooked. Now scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) are making a concerted push to take thermal energy storage to the next level.

Oak Ridge National Laboratory: New scalable method resolves materials joining in solid-state batteries

ORNL scientists developed a scalable, low-cost electrochemical pulse method to improve the contact between layers of materials in solid-state batteries, resolving a key challenge in energy-dense solid-state batteries. Credit: Andy Sproles/ORNL, U.S. Dept. of Energy Scientists at the Department of Energy’s Oak Ridge National Laboratory have developed a scalable, low-cost method to improve the joining of materials in solid-state batteries, resolving one of the big challenges in the commercial development of safe, long-lived energy storage systems.

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.
