Due to their polymorphism, TiO2 films are quintessential components of state-of-the-art functional materials and devices for various applications from dynamic random access memory solar water splitting. However, contrary other semiconductors/dielectric materials, the relationship between structural/morphological electrical properties at nano microscales remains unclear. In this context, morphol...

This study presents performance of upflow anaerobic sludge blanket (UASB) reactor in treating liquefied fleshings (LFs) with tannery wastewater (TWW) using liquefaction reactor (LR). With increase in recirculation rate, methane production increased in LR than in UASB reactor due to methanogenic bacteria in LR. UASB reactor with continuous feeding of LFs and TWW resulted with cumulative methane ...

A novel plasma-driven catalysis (PDC) reactor with special structure was proposed to remove vehicle exhaust gas. The PDC reactor which consisted of three quartz tubes and two copper electrodes was a coaxial dielectric barrier discharge (DBD) reactor. The inner and outer electrodes firmly surrounded the outer surface of the corresponding dielectric barrier layer in a spiral way, respectively. Na...

A mesophilic unsaturated flow (trickle bed) reactor was designed and tested for H2 production via fermentation of glucose. The reactor consisted of a column packed with glass beads and inoculated with a pure culture (Clostridium acetobutylicum ATCC 824). A defined medium containing glucose was fed at a flow rate of 1.6 mL/min (0.096 L/h) into the capped reactor, producing a hydraulic retention ...

Increasing the distance from which an antineutrino detector is capable of monitoring the operation of a registered reactor, or discovering a clandestine reactor, strengthens the Non-Proliferation of Nuclear Weapons Treaty. This report presents calculations of the reactor antineutrino interactions, from both quasi-elastic neutrino-proton scattering and elastic neutrino-electron scattering, in a ...

This article describes the use of biofilm reactors for the production of various chemicals by fermentation and wastewater treatment. Biofilm formation is a natural process where microbial cells attach to the support (adsorbent) or form flocs/aggregates (also called granules) without use of chemicals and form thick layers of cells known as "biofilms." As a result of biofilm formation, cell densi...

The scope of this work was to optimize the reactant delivery parameters for plasma enhanced chemical vapor deposition (PECVD) p-type Cu2O films from Cu(hfac)(tmvs), with aim explore an alternative other large-area techniques such as sputtering. While n-type metal oxide semiconductors amorphous indium gallium zinc have now been developed and offer significantly improved device performance over h...

We report on low-temperature and low-pressure deposition conditions of 140 °C 1.5 mTorr, respectively, to achieve high-optical quality silicon nitride thin films. deposit the films using an electron cyclotron resonance plasma-enhanced chemical vapour (ECR-PECVD) chamber with Ar-diluted SiH4, N2 gas. Variable-angle spectroscopic ellipsometry was used determine thickness refractive index films, w...
