electrical sensitivity of a boron nitride nanotube (bnnt) was examined toward aniline (c6h5nh2) molecule by using density functional theory (dft) calculations at the b3lyp/6-31g (d) level, and it was found that the adsorption energy (ead) of aniline on the pristine nanotubes is a bout -19.03kcal/mol. but when nanotube has been doped with si and al atomes, the adsorption energy of aniline molecu...
High pulsed electrical field as pre-processing step for fruits and vegetables in the vacuum freeze drying could increase drying rate efficiency and preserve nutritional ingredients in maximum. Moreover, high pulsed electrical field pretreatment has been successfully used to solve practical problems in the vacuum freeze drying, such as energy consumption, high production costs and long drying ti...
in this paper an optimal controller is proposed for a self-balancing electrical vehicle called segway pt. this vehicle has one platform and two wheels on the sides and the rider stands on the platform. a handlebar, as a navigator, is attached to the body of segway, with which the rider controls the vehicle. since segway uses electrical energy produced by batteries, resource consumption manageme...
The electrocoagulation (EC) is a simple and efficient method for the treatment of many water and wastewaters.The kinetics of decolorization of Acid Yellow 23 by EC using iron electrodes was studied. Theelectrodecolorization rate follows pseudo-first order kinetic with respect to the AY23 concentration havingkapp= 5.65 cm min-1 at T= 295 K. The rate equation is as follows:ln [AY23]t – ln [AY23]0...
The solar radiation energy is one of the clean, essential and renewable resources for future. Iran, having 300 annual sunny days, has such intrinsic potential and thermosyphon solar-electrical water heaters (TSEWH) are the simplest solar-thermal convertors. Despite their unique merits, they can not supply hot water for domestic applications during cold period, so, an auxiliary backup system suc...
Eric Yeatman Optical and Semiconductor Devices Group, Department of Electrical and Electronic Engineering, Imperial College London, South Kensington Campus, Exhibition Road, London, SW7 2AZ, United Kingdom We propose a new way to deliver power to biomedical implants in order to address the higher energy requirements of microsystems with actuation functions such as drug release or mechanical adj...
Abstract Introduction: Phenol is amongst the dangerous environmental pollutants, which due to its presence in the industrial effluents, should be removed. Objective: The aim of this study was to evaluate the efficiency of catalytic ozonation by calcined scallop shell as a catalyst in the removal of phenol Materials and Methods: Scallop shells were collected from the coast of Caspian Sea in G...
The control strategy for Direct Wave Energy Converters (DWEC) is often discussed without taking into account the physical limitations of electric Power Take-Off (PTO) system. This inappropriate modelling assumption leads to a non-realistic or a bad use of the electric systems, that leads to a failure to minimize the global ”per-kWh” system cost. We propose here a Model Predictive Control (MPC) ...
Fuel cells directly convert chemical energy into electrical power using electrochemical reactions. Solid oxide fuel cell (SOFC) is one of the high-temperature fuel cells that propose a promising future from the standpoint of power generation. In this study, optimization of an SOFC system is performed using Taguchi approach after verification of the model in compare with experimental results. Cu...
