TL;DR: In this article, the authors present a review of current technologies for the management of produced water, examines how electrochemical techniques may be used in these areas and compares the prospects for future development, since produced water is a potential electrolyte because it has a relatively good conductivity.
Abstract: Produced water is a complex mixture of organic and inorganic compounds and the largest volume of by-product generated during oil and gas recovery operations. The potential of oilfield produced water to be a source of fresh water for water-stressed oil-producing countries and the increasing environmental concerns in addition to stringent legislations on produced water discharge into the environment have made produced water management a significant part of the oil and gas business. This article reviews current technologies for the management of produced water, examines how electrochemical techniques may be used in these areas and compares the prospects for future development. It suggests that treatment technologies based on electrochemistry could be the future of produced water management, since produced water is a potential electrolyte because it has a relatively good conductivity. It also explains that by applying photoelectrochemistry, water electrolysis, fuel cell and electrodeposition, electrochemical engineering could achieve energy storage, production of clean water and recovery of valuable metals from produced water with minimal or no negative impact on the environment.

TL;DR: A comprehensive review of water desalination systems, whether operated by conventional energy or renewable energy, to convert saline water into fresh water is presented in this paper, where the advantages and disadvantages, including the economic and environmental aspects, of these systems are presented.
Abstract: Water is one of the earth's most abundant resources, covering about three-quarters of the planet's surface. Yet, there is an acute shortage of potable water in many countries, especially in Africa and the Middle East region. The reason for this apparent contradiction is, of course, that 97.5% of the earth's water is salt water in the oceans and only 2.5% is fresh water in ground water, lakes and rivers and this supplies most human and animal needs. Tackling the water scarcity problem must involve better and more economic ways of desalinating seawater. This article presents a comprehensive review of water desalination systems, whether operated by conventional energy or renewable energy, to convert saline water into fresh water. These systems comprise the thermal phase change and membrane processes, in addition to some alternative processes. Thermal processes include the multistage flash, multiple effects boiling and vapour compression, cogeneration and solar distillation, while the membrane processes include reverse osmosis, electrodialysis and membrane distillation. It also covers the integration into desalination systems of potential renewable energy resources, including solar energy, wind and geothermal energy. Such systems are increasingly attractive in the Middle East and Africa, areas suffering from shortages of fresh water but where solar energy is plentiful and where operational and maintenance costs are low. The advantages and disadvantages, including the economic and environmental aspects, of these desalination systems are presented.

TL;DR: In this article, a review of the state-of-the-art and new trends in developing efficient two-component composites for various AHT cycles is presented, including adsorption chilling, desiccant cooling, heat storage and regeneration of heat and moisture in ventilation systems.
Abstract: Adsorption heat transformation (AHT) is one of the challenging technical approaches for supporting the world community initiatives to alleviate or reverse the gravity of the problems arising from CO 2 emissions and global warming. The key tool for enhancement of the AHT efficiency and power is a harmonization of adsorbent properties with working conditions of the AHT cycles. It can be realized by means of target-oriented designing the adsorbent specified for a particular AHT cycle. Two-component composites ‘salt in porous matrix’ (CSPMs) offer new opportunities for nano-tailoring their sorption properties by varying the salt chemical nature and content, porous structure of the host matrix and synthesis conditions. CSPMs have been recognized as promising solid sorbents for various AHT cycles, namely adsorption chilling, desiccant cooling, heat storage and regeneration of heat and moisture in ventilation systems. In this review, we survey a current state-of-the-art and new trends in developing efficient CSPMs for various AHT cycles. Copyright , Oxford University Press.

TL;DR: In this paper, an aluminum heat sink was used in order to dissipate waste heat from a photovoltaic (PV) cell and an experimental research concerning the effects of passive cooling on performance parameters of silicon solar cells was presented.
Abstract: In this study, an experimental research concerning the effects of passive cooling on performance parameters of silicon solar cells was presented. An aluminum heat sink was used in order to dissipate waste heat from a photovoltaic (PV) cell. Dimensions of the heat sink were determined considering the results of a steady-state heat transfer analysis. The experiments were carried out for different ambient temperatures and various illumination intensities up to 1 sun under solar simulator. Experimental results indicate that energy, exergy and power conversion efficiency of the PV cell considerably increase with the proposed cooling technique. An increase of ∼20% in power output of the PV cell is achieved at 800 W/m-super-2 radiation condition. Maximum level of cooling is observed for the intensity level of 600 W/m-super-2. Performance of PV cells both with and without fins increases with decreasing ambient temperature. Copyright , Oxford University Press.

TL;DR: Aerogels are a special type of solid material with nanometre-scale pores < 1/3000th the width of a human hair as mentioned in this paper, and their porosity is in excess of 90%, in some cases as high as 99.9%.
Abstract: Aerogels are a special type of solid material with nanometre-scale pores <1/3000th the width of a human hair. Porosity is in excess of 90%, in some cases as high as 99.9%, and densities can be as low as 3 kg/m-super-3. Aerogels are essentially ‘puffed-up sand’ and are often termed ‘frozen smoke’. Their thermal conductivity (0.014 W/m K at room temperature) is the lowest of any solids, and they also have good transparency. The acoustic properties of aerogels make them effective insulators against noise, and aerogels have the lowest refractive index, and dielectric constant of all solid materials. The unusual properties of aerogels open the way to a new range of opportunities for their application in buildings. This paper provides information on their unique features and reviews the potential applications for aerogels in buildings as well as latest developments in the field.
