Laurell Technologies WS-400 spin coater used to apply photoresist to the surface of a silicon wafer. Spin coating is a procedure used to deposit uniform thin films onto flat substrates. Usually a small amount of coating material in liquid form is applied on the center of the substrate, which is either spinning at low speed or not spinning at all.
A fluid reservoir to store the main supply of coating fluid for the system; A pump to drive the coating fluid through the system; A slot-die to distribute the coating fluid across the desired coating width before coating onto the substrate; A substrate mounting system to support the substrate in a controlled manner as it moves through the system
A typical co-axial electrospinning setup. Two concentrically parallel needles form the co-axial spinneret. A composite Taylor cone formulates at the orifice of the needle encompassing the two solutions, fed to the needle from two independent reservoirs (syringe pumps). In this example, a negatively charged mandrel is used as a collector.
Aluminising vacuum chamber at Mont Mégantic Observatory used for re-coating telescope mirrors. [1] Vacuum deposition is a group of processes used to deposit layers of material atom-by-atom or molecule-by-molecule on a solid surface. These processes operate at pressures well below atmospheric pressure (i.e., vacuum). The deposited layers can ...
Physical vapor deposition (PVD), sometimes called physical vapor transport (PVT), describes a variety of vacuum deposition methods which can be used to produce thin films and coatings on substrates including metals, ceramics, glass, and polymers. PVD is characterized by a process in which the material transitions from a condensed phase to a ...
The final U.S. Figure Skating Championships before the 2026 Milan Olympics will take place in St. Louis. U.S. Figure Skating announced Monday the 2026 nationals would be Jan. 5-11 at the ...
They are important tools for improving the performance of many vacuum systems. Sintered onto the inner surface of high vacuum vessels, the NEG coating can be applied even to spaces that are narrow and hard to pump out, which makes it very popular in particle accelerators where this is an issue. The main sorption parameters of the kind of NEGs ...
Sputter coating in scanning electron microscopy is a sputter deposition process [clarification needed] to cover a specimen with a thin layer of conducting material, typically a metal, such as a gold/palladium (Au/Pd) alloy. A conductive coating is needed to prevent charging of a specimen with an electron beam in conventional SEM mode (high ...
