WebGlow discharge treatment with air will make film surfaces negatively charged and hydrophilic and allow the easy spread of aqueous solutions. This and other processes are outlined below. ... Glow Discharge Process: Surface State: Charge: Atmosphere: Typical applications: Hydrophilic: Negative: Air: Carbon coated TEM grids: Hydrophilic: Positive ... WebHence, the latter processes make the glow discharge a self-sustaining plasma. The use of the glow discharge as an ion source for mass spectrometry is based on the phenomenon of sputtering. The material to be analysed serves as the cathode of the glow discharge. The argon ions from the plasma (and also fast argon atoms) that bombard the cathode ...
WebThe use of ultraviolet light alone (14) as well as the use of electrically excited plasmas or glow discharges to generate monomers capable of undergoing VDP have been explored. The products of these two processes, called plasma polymers, continue to receive considerable scientific attention. WebThe GloQube® Plus uses a single door with two independent vacuum chambers and adjustable sample stages. The in-air chamber is for simple glow discharge hydrophilic applications, while the in-vapour chamber is designed for hydrophobic (negative or positive) conversions, typically using reagents such as methanol and amylamine.
