In this work, a simple, low-cost and effective multifunctional mod-ification strategy is developed by introducing the k-Carrageenan (k-C) as the interfacial layer of SnO2/per-ovskite. The sulfate groups of k-C not only play a positive role in passivating the Sn4+ from SnO2 film, ...
In physics, energy is defined as the capacity for doing work, but this definition is not very helpful in this context. Thus, we use the concept of an ‘energy system’, which consists of two separate sub-systems: the energy supply system and the energy demand system [24].1 The energy ...
More market transparency: Increasing the transparency of derivatives markets can cut the differences in information different firms have so all firms and traders can properly manage their risk. This can be done through reporting requirements for traders and positions, as well as publishing the aggregate...
Adsorption Energy In subject area: Engineering Adsorption energy (Ea) of an adsorbed atom is the energy, which has to be delivered to the adsorbed atom to be desorbed from the surface. From: Materials Surface Processing by Directed Energy Techniques, 2006 About this pageAdd to MendeleySet alert...
Work is said to be done when a force (push or pull) applied to an object causes a displacement of the object. We define the capacity to do the work as energy. Power is the work done per unit of time. This article discusses work, energy and power in detail. Table of Contents What ...
BAIT, with the tightness of the fit indicating the model’s capability to predict demand.f, Comparison of historical daily electricity demand with the model estimate covering the entire span of metered data. Demand is measured in terms of average power demand through the day in gigawatts. Gaps ...
However, they found that in the case of van der Waals two-body interactions the binding energies at unitarity are approximately given solely in terms of the van der Waals length. It has not been reported how the relationship between EN+1/EN−1 and EN/EN−1 changes when moving away ...
In recent years, in comparison to the traditional way of natural gas transportation (pipelines), the LNG market has become more attractive in relation to the flexibility in its transportation and in terms of destination choices [2]. In Europe, the high management and realization costs of pipeline...
Review papers provide great insight into the work done to improve the energy efficiency of machining processes. For example, Zhang et al. [4] focused on theoretical and experimental models in the preview of energy efficiency of machine tools, Yoon et al. [5] reported on energy-saving strategie...
So, in the second part of the analysis, we started the exergy analysis of the IC engine by defining the exergy balance. The ratio of work done (BP) produced at the output shaft to the input fuel energy(Qin) is termed as the piston thermal efficiency of the engine control volume, as ...
