Photocatalytic Reactor using TiO2 Thin Film on Quartz Tubes
… The wok involves the deposition of TiO2 on quartz tubes with TiO2 and TiO2-Fe doped film by sol-gel and ESA (electrostatic self assembly) method and testing the performance of the coated film in proposed photocatalytic reactor in degradation of congo red, KI and Nitro phenol.</p>

Synthesis of Novel Cyclobutane Nucleoside Analogues
… ketones was carried out in methanol using quartz tubes to promote ring-expansion isonucleoside products. Photolysis did not yield any ring-expansion or cycloelimination products, rather, the products are suspected to be cyclopropanes from decarbonylation of the ketones, since these are less …

Experimental investigation of the flow field during combustion in narrow circular ducts
… of methane-oxygen mixtures inside small diameter quartz tubes yielded cycles of ignition, flame propagation, and extinction. This phenomenon was studied with the intent of determining the flow structure that underlay the observed oscillatory motion. The fluid motion during the oscillations was …

Microplasma antennas: characterizing capillary plasma discharges as potential monopole antennas
… use of capillary plasma elements, in glass and quartz with sub-millimeter inner diameters and 1-5 cm in length, as monopole antenna elements. Plasma elements of this size have not been demonstrated before, as most plasma antennas use fluorescent tubes with inner diameters greater than 2 cm and …

Microwave plasma synthesis of nano-sized silicon carbide at atmospheric pressure
… a stub tuner, a waveguide and a sliding short. Quartz tubes were used, in which the plasma was generated and maintained. Hydrogen served as an added reductant for the conversion reaction, and argon served as the MTS carrier gas. The parameters studied were the H2:MTS molar ratio and the total …

Experimental investigation of flame propagation in long, narrow tubes
… propane-air flames propagating in horizontal quartz tubes of small diameter (6.4 mm) was studied using high-speed photography and Particle Streak Velocimetry (PSV). Several regions of propagation were established, including an initial region of uniform propagation, a subsequent region of …

Synthesis and characterization of precursors for chemical vapor deposition of metal oxide thin films
… decomposition studies were executed in sealed quartz tubes. Products of decomposition were examined by infrared spectrometry, mass spectrometry, and solid state NMR spectrometry. Metal oxide formation from decomposition of precursors was observed at; 300-350 °C for T8, 350-550 °C for Zr(thd)₄, …

Oxidation kinetics of molten copper sulphide
… at specific reaction times, using U-shaped quartz tubes. The samples were examined microscopically to determine the reaction progress based on the characteristics of gas bubbles, copper droplets and the phases present. The oxidation reaction of molten copper sulphide was found to take place …
