    摘要： Disclosed is a device and method for contacting a biological substrate. A non-thermal plasma device delivers a non-thermal plasma discharge using a dielectric conduit, an igniter electrode and a RF electrode. The dielectric conduit fluidicly communicates a gas therethrough and an igniter electrode ionizes at least a portion of the gas. The RF electrode, disposed circumferentially proximate to the exterior of the dielectric conduit, generates non-thermal plasma from the ionized gas. The non-thermal plasma is discharged from the dielectric conduit and contacts a biological substrate. The non-thermal plasma discharge may be suitable for tissue bonding and sterilization applications.

    摘要： Provided are a method and a device for producing nanoparticles of a low melting point material such as gold at more than 10 times faster the rate of conventional technology while maintaining the time-averaged temperature of pulse-modulated atmospheric-pressure plasma at a temperature that is low enough so as not to damage a heat-sensitive material disposed downstream. This method of preparing nanoparticles of a low melting point inorganic material in which a wire made of a low melting point inorganic material is inserted into a plasma-generating capillary tube or a plasma-generating nozzle and atmospheric-pressure high frequency plasma is generated in the capillary tube or nozzle is characterized by generating the plasma by applying a high frequency voltage possessing a waveform which exhibits its maximum value when it rises and then immediately falls, and which is pulse-modulated so that the duty ratio thereof is 10% or less.

    摘要： The invention is directed to a method and an arrangement for cleaning optical surfaces of reflection optics which are arranged in a plasma-based radiation source or exposure device arranged downstream and contaminated by debris particles emitted by a hot plasma of the radiation source. It is the object of the invention to find a novel possibility for in-situ cleaning of the optical surfaces of reflection optics which are contaminated by debris in plasma-based radiation sources so as to allow an integrated generation of known gas radicals and the isotropic distribution thereof on the contaminated optical surfaces. According to the invention, this object is met in that the gas radicals are generated by dielectrically impeded discharge between two surface electrodes along the entire optical surface. The gas radicals are generated almost exclusively by electron transfer on at least one barrier layer which covers the entire surface of at least one of the surface electrodes, an AC voltage in the Hz to kHz range is applied to the surface electrodes for periodically eliminating the charge polarization at the barrier layer so that a cold plasma is generated continuously and the deposited debris particles are removed as gaseous reaction products by the gas flow guided over the optical surface.
