The corona-induced simultaneous removal of NO/sub x/ and SO/sub 2/ from flue gas, which is based on the application narrow voltage pulses to an electrode structure similar that electrostatic precipitator studied. free electrons corona discharge, having energy up 20 eV, originate active radicals lead transformation into their acids, can be neutralized salt particulate by adding gas a basic compound, such as ammonia or calcium hydroxide. process has been investigated with test rig installed in...
In the past decade, hydrogels have attracted growing interest for emerging applications in flexible electronic devices, human–machine interactions, energy supply, or storage. Developing a multifunctional gel architecture with superior ionic conductivity and good mechanical flexibility is bottleneck to overcome. Herein, poly(vinyl alcohol)/sulfuric acid (PVA–H2SO4) were prepared via freeze–thaw method. With aim of tuning formulation view possible application storage, effects different...
This research study aims to explore the synergistic effects of incorporating polyvinylidene fluoride (PVDF) into polyvinyl alcohol (PVA) hydrogels enhance their suitability for triboelectric sensors applications. The preparation process employs a method freezing/thawing conducted in dimethyl sulfoxide (DMSO), followed by solvent replacement with water. approach effectively preserves PVDF its α phase, eliminating piezoelectric and enhancing hydrogels' mechanical properties. use DMSO...
Collagen and gelatin methacryloyl (GelMA) are widely studied biomaterials for extrusion-based bioprinting (EBB) due to their excellent biological properties ability mimic the extracellular matrix of native tissues. This study aims establish a preliminary workflow approaching EBB by assessing collagen GelMA printability performance. was selected its cost-effectiveness ease synthesis, while our formulation specifically optimized printability, which is challenging aspect bioprinting. A parallel...
Using phenol as a model organic pollutant we studied and characterized an innovative advanced oxidation process in water using prototype dielectric barrier discharge (DBD) reactor which electrical discharges are produced the air above surface. Phenol is decomposed quite efficiently this operated at room temperature atmospheric pressure. The selectivity to form CO2 is, however, be improved since large fraction of treated carbon unaccounted for. rate conversion increases linearly with...
In this paper, the electrical characteristics of positive pulsed corona in a wire-cylinder type reactor are investigated. The injected energy and charge into discharging volume per pulse unit length emitting wire adopted to evaluate power source, electric circuits, wire. current lasts from several hundred nanoseconds few microseconds. current, peak values, can reach up 60 A/m, 5 MW/m, 480 mJ/m, 8 /spl mu/C/m, respectively. conversion efficiency related output forming capacitor delivered 90%....
This work describes a simple, inexpensive, and robust method to prepare flexible “all in one” integrated hydrogel supercapacitors (HySCs). Preparing smart hydrogels with high electrical conductivity, ability stretch significantly, excellent mechanical properties is the last challenge for tailored wearable devices. In this paper, we employed physical crosslinking process that involves consecutive freezing thawing cycles polyvinyl alcohol (PVA)-based hydrogel. Exploiting self-healing of these...
Experiments carried out to describe the corona occurring in wire-cylinder geometries due short voltage pulses of positive polarity, and assess influence current on energy associated with each pulse both electrode geometry waveshape are reported. The experimental setup is described. data presented, functions that fit them adequately given. Within range tested values, it was found diameter wire did not exhibit any significant influence. cylinder appears very remarkable, but if one considers...
To assess the benefits of impulse energization with different coals, experimental industrial research was performed at a 70 MWe thermal power plant. Two technologies for supplies were tested over 10000 h operation. The results tests, according to ASME standards, demonstrated that has great advantages conventional and ensures collection efficiency from 99.6 99.9%, corresponding emission levels below 50 mg/Nm/sup 3/, reduction in absorbed about 0.5 0.1 Wh/Nm/sup 3/. Tests showed there...

The wet-contaminant method was used, alternating direct voltages related different values distributions thickness, width resistivity contaminant layer. results show that voltage polluted strip depends strongly surface conductivity slightly thickness. nonuniformity giving rise over length polluting does not affect voltage.
Trigatron spark-gap discharges with very long time lags to breakdown were observed and their characteristics investigated in order determine the discharge mechanism. The main voltage was applied a predetermined delay after trigger pulse, lag of many hundreds microseconds at voltages from 30 80% untriggered has been observed.
