Sugar binding proteins and binders of intermediate sugar metabolites derived from microbes are increasingly being used as reagents in new and expanding areas of biotechnology. The fixation of carbon dioxide at emission source has recently emerged as a technology with potentially significant implications for environmental biotechnology. Carbon dioxide is fixed onto a five carbon sugar D-ribulose...

Textile dyes are some of the most refractory organic compounds in the environment due to their complex and various structure. An integrated resin adsorption/Dielectric Barrier Discharge (DBD) plasma regeneration was proposed to treat the indigo carmine solution. It is the first time to report ectopic regeneration of the saturated resins by non-thermal Dielectric Barrier Discharge. The adsorptio...

in this paper, startup performance of upflow anaerobic hybrid reactor and upflow anaerobic sludge blanket reactors in anaerobic treatment of distillery spentwash has been studied under identical conditions of operation. various effluent characteristics like ph, electrical conductivity, chemical oxygen demand, biochemical oxygen demand and total solids and other process parameters like biogas p...

The manipulation of bubbles and the ignition of microplasma within a 200 nL bubble at atmospheric pressure and in an inert silicone oil environment were achieved. Driven by dielectrophoresis (DEP), bubble generation, transportation, mixing, splitting, and expelling were demonstrated. This process facilitated the preparation of various bubbles with tuneable gas compositions. Different gas bubble...

This paper provides an attempt to measure the pressure distribution actuated by dielectric barrier discharge (DBD) actuator. The efficacy of DBD plasmas driven by repetitive nanosecond (NS) pulses for pressure distribution is investigated experimentally in quiescent air. The NS pulse driven DBD plasma actuator (NS-DBD hereafter, transfers very little momentum to the neutral air, so the value of...

Approximately 1.5 billion tyres are produced each year which will eventually enter the waste stream representing a major potential waste and environmental problem. However, there is growing interest in pyrolysis as a technology to treat tyres to produce valuable oil, char and gas products. The most common reactors used are fixed-bed (batch), screw kiln, rotary kiln, vacuum and fluidised-bed. Th...

Effect of fractional gas hold-up εG on volumetric mass transfer coefficient KLa were studied for two different type of airlift contactors conventional and modified. KLa was directly proportional to gas hold-up within bubbly flow regime (UG < 0.075 m/s ) in conventional one but reverse trend ( inversely proportional) was reported in modified airlift contactor. Mathematical relation between KLa a...

The first considered problem is the problem of arising dynamic dissipative structures in the chemical reactor volume. The mathematical model of heat and mass transfer in the tubular through-reactors has been submitted. The model consists of the diffusion-kinetic equations for two reagents under the first-order reversible reaction and heat transfer equation with allowance for the latent heat of ...
