Nanostructured Er3+ doped TiO2 thin films are deposited onto glass substrate via sol-gel dip-coating followed by calcination at 450 °C for 1 h. X-ray diffraction analysis confirms that the films crystallized within single tetragonal anatase phase. Atomic force microscopy observations reveal that the surface of pure TiO2 is characterized by [...]

ZnO/TiO2 coatings are deposited onto 304 stainless steel substrates by using sol-gel dip-coating technique followed by subsequent annealing. X-ray diffraction analysis reveals nanocrystalline ZnO and TiO2 phases for all multilayered films except 1ZnO/1TiO2 with amorphous nature. Optical microscopy images show the presence of some streaks, holes, scratches and micro-traces, meanwhile [...]

Sensors are devices that detect a physical, chemical, or biological stimulus and give a response in the form of a measurable signal. The increasing number of applications for sensing technologies has increased the need for the development of a variety of new sensors with far better performance. Nanoparticles are at [...]

Summary: In this study four catalysts (ƴ –Alumina, α- Alumina, silica gel and silica ppt) with different physicochemical characteristics were tested for the pyrolysis of polystyrene (PS) under inert atmosphere in the temperature range 200-650 °C at heating rate 5 °C/min. The silica gel a mesoporous catalyst, with a greater [...]

In this work, thermogravimetric analysis of sesame biomass samples was conducted in inert atmosphere at heating rate of 10 °C/min in the temperature range 30–1000 °C. Kinetic parameters were calculated applying the Coats-Redfern (CR) method. TG/DTG of sesame biomass showed that pyrolysis mainly occurred in the temperature range 205–412 °C. Therefore, the biomass [...]

Microalgae cultivation and their use is a promising approach for integrated CO2 biofixation, wastewater treatment and renewable energy production. To develop such an important technology, there is a need to optimize the culture conditions, maximizing CO2 consumption, degrading the nutrients present in the wastewater and maximise the microalgae biomass production. [...]

This paper suggests an alternate improved setup of connecting a photovoltaic generator (PVG) with the power grid. The proposed improved setup uses a single phase full wave controlled bridge rectifier working in an inverter mode of operation. The controlled bridge rectifier is operated in such a way that it should [...]

Purpose: The purpose of this study is to present a hybrid approach to model and predict long-term energy peak load using Bayesian and Holt–Winters (HW) exponential smoothing techniques. Design/methodology/approach: Bayesian inference is administered by Markov chain Monte Carlo (MCMC) sampling techniques. Machine learning tools are used to calibrate the values [...]

Blockchain, is the new trending revolution innovation that leverages business process and data sharing, by eliminating the centralization or intermediates. The technology has been attracting huge attention and many organizations are looking to adopt it. The decentralization, security immutability, data sharing and other blockchain advantages that have been explored reinforce [...]

Flexible AC Transmission System (FACTS) technology is one of the innovative solutions which were proposed to obtain better utilization and controlling of power over the transmission network in steady state and transient conditions. Unified Power Flow Controller (UPFC) is selected in this study as it is considered as the most [...]
