Recent advancements in water emulsion fuel to explore efficient and cleaner production from various biodiesels: A retrospective review

An Experimental Study on the Performance and Emissions of an 8% Water-in-Diesel Emulsion Stabilized by a Hydrophilic Surfactant Blend

“…A wide variety of methods have been tested and used to develop WiDE fuels [31] Figure 2. Micro-explosion in a fuel droplet (adapted from [8]).…”

“…Water-in-Diesel Emulsion (WiDE), falling within the latter category, marks a notable stride in technology, serving as an alternative fuel for seamless integration into diesel engines, which can potentially offer the dual benefit of enhanced combustion efficiency and emissions reduction. The versatility of WiDE potentially functioning as a drop-in fuel An emulsion is commonly described as a dispersion consisting of t miscible phases, held together and mixed by chemical processes and/or m [7,8]. To secure the stability of these blends, surfactants are often used to primary role of these amphiphilic molecules is to lower the interfacial tens different liquids and diminish the a raction between molecules of the [10].…”

“…K solutions are commonly referred to as nanoemulsions and are stable fo (the dispersed droplets are held in suspension due to Brownian motion). M are thermodynamically stable, remaining in their lowest energy state, ach equilibrium with the environment, and therefore exhibiting a long shelf-l phase emulsions are usually divided into w/o and oil-in-water, depending sition of each phase [8]. WiDE are classified as w/o emulsions where diese ous phase and water is the dispersed phase.…”

All-in-One Cast-Molded Hydrophobic Silicon Dioxide-Phase Change Microcapsule/Gelatin-Hydroxyethyl Cellulose Composite Aerogel for Building Cooling

“…The thermal comfort of buildings has a significant impact on human health, work efficiency, and quality of life. , Typically, the maintenance of thermal comfort in buildings is based on active energy-consuming equipment such as heating, ventilation, and air conditioning (HVAC). , According to the International Energy Agency (IEA), heating and cooling account for about half of the world’s energy consumption, and most of this energy comes from inefficient use of fossil fuels or biomass, which is responsible for more than 40% of global carbon emissions from energy. , With global climate change and rising energy costs, energy consumption in this sector will continue to increase. This is not only a serious economic burden but also leads to serious environmental problems, including global warming, − air pollution, − and acid rain. − Passive daytime radiative cooling (PDRC) has great potential as a green, nonelectric cooling technology to address today’s building cooling challenges. − …”
