In the search for clean energy alternatives to fossil fuels, one promising solution relies on photoelectrochemical (PEC) cells – water-splitting, artificial-photosynthesis devices that turn sunlight and water into solar fuels such as hydrogen. In just a decade, researchers in the field have achieved great progress in the development of PEC systems made of light-absorbing gold nanoparticles – tiny spheres just billionths of a meter in diameter – attached to a semiconductor film of titanium dioxide nanoparticles (TiO2 NP). But despite these advancements, researchers still struggle to make a device that can produce solar fuels on a commercial scale.
DENVER--(BUSINESS WIRE)--Aug. 6, 2020-- Advanced Energy (Nasdaq: AEIS) – a global leader in highly engineered, precision power conversion, measurement and control solutions – today introduces its new industry-leading Ascent® MS multi-output power supply system. Designed to enable the lowest system and infrastructure costs in the industry for solar photovoltaic (PV) plasma-enhanced chemical vapor deposition (PECVD) systems, the Ascent MS builds on Advanced Energy’s long legacy of bringing power system innovation to the manufacturing of advanced solar cells.
If you’ve eaten vegan burgers that taste like meat or used synthetic collagen in your beauty routine – both products that are “grown” in the lab – then you’ve benefited from synthetic biology. It’s a field rife with potential, as it allows scientists to design biological systems to specification, such as engineering a microbe to produce a cancer-fighting agent. Yet conventional methods of bioengineering are slow and laborious, with trial and error being the main approach.
Oak Ridge National Laboratory and Department of Energy officials dedicated the launch of two clean energy research initiatives that focus on the recycling and recovery of advanced manufacturing materials and on connected and autonomous vehicle technologies. Daniel R Simmons, DOE’s Assistant Secretary for Energy Efficiency and Renewable Energy, joined Moe Khaleel, ORNL’s deputy for projects, for ribbon cutting events at the Manufacturing Demonstration Facility and the National Transportation Research Center.
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.
