A highly efficient, continuous wave 172nm Xenon excimer lamp scalable in power, size and geometry is reported. Data from a prototype device based on multiple corona discharges, operating in dense Xenon gas, confirmed the concept. Results imply that large lamps with uniform VUV-light output exceeding 100mW/cm and wall plug electrical power to VUV light conversion efficiencies approaching 50% can...

Plasma technology reaches rapidly increasing efficiency in catalytic applications. One such application is the splitting reaction of CO2 to oxygen and carbon monoxide. This could be a cornerstone power-to-X processes that utilize electricity produce value-added compounds as chemicals fuels. However, it poses problems practice due its highly endothermal nature challenging selectivity. In this co...

We developed a novel discharge valve characters usmg the stopper to obtain the high efficiency reciprocating compressor for refrigerators. Generally, the sticky force occurred due to the shape of valve, stopper and oil between the valve and valve seat changed the process of valve motion and valve dynamics of compressor. In this paper, we can measure the characteristics of the sticky force and d...

This paper presents a study of the relationship between Electrical Discharge Machining (EDM) parameters on the EDM efficiency factors using a full factorial design, based on pulse on-time, duty cycle and tool polarity parameters in EDM machining of AISI H13 tool steel. The results show that, in positive polarity, the plasma flushing efficiency and pulse efficiency increase according to the puls...

One possible solution to mitigating the effects of high atmospheric concentrations of carbon dioxide (CO2) is the use of a plasma source to break apart the molecule into carbon monoxide (CO) and oxygen. This work experimentally investigates the efficiency of dissociation of CO2 in a 1-kW radio-frequency (rf) plasma source operating at 13.56-MHz in a low-pressure discharge. Mass spectrometry dia...
