many researchers have investigated how to increase the overall efficiency of solar-driven thermal systems. several key parameters, such as collector efficiency and storage tank characteristics, may impose some constraints on the annual solar fraction (asf) of such systems. in this paper, the behaviour of integrating the phase change material (pcm) in sdhw systems is modelled and optimized numer...

Awareness of climate change and the threat of rising energy prices have resulted in increased attention being paid to energy issues, and industry seeing a cost benefit in using more energyefficient production processes. One energy-efficient measure is the recovery of industrial excess heat. However, this option has not been fully investigated and some of the technologies for recovery of excess ...

Fatty acids and fatty alcohols have the advantages of high latent heat phase change, good thermal stability, no corrosion, supercooling separation. They can be used as change energy storage materials for passive temperature control. However, their popularization application are limited because transition narrow range. This study develops a novel binary composite (PCMs) Capric acid (CA) Octadeca...

Manipulating optical signals below the diffraction limit is crucial for next-generation data-storage and telecommunication technologies. Although controlling the flow of light around nanoscale waveguides was achieved over a decade ago, modulating optical signals at terahertz frequencies within nanoscale volumes remains a challenge. Since the physics underlying any modulator relies on changes in...

in this paper, we studied effect of different parameters including density, viscosity, interfacial tension and solute transfer concentration on phase inversion hold-up. the results showed that change in phase density ratio had no effect on phase inversion hold-up. it also disclosed that the phase viscosity ratio was the most effective parameter affecting phase inversion hold-up and each phase h...

Nanoscale memory devices, whose resistance depends on the history of the electric signals applied, could become critical building blocks in new computing paradigms, such as brain-inspired computing and memcomputing. However, there are key challenges to overcome, such as the high programming power required, noise and resistance drift. Here, to address these, we present the concept of a projected...
