During the basic operation of a lithium-sulfur (Li-S) cell, sulfur molecules are required to undergo a complex mix of electrochemical and chemical reaction processes. To date, almost all modeling of Li-S cell behavior has been undertaken using electroneutral, structurally homogenized, cell scale models accounting for most of these processes. The presented work was undertaken in order to try and ...

Carbon fiber as filaments or as continuously reinforced composite finds application in the electronic packages, electric vehicles, and electrical machines, owing to its excellent electromagnetic (EMI) shielding and high conductivity. Carbon fiber being good conductor of electricity (in the order of 105 S/m), and the binding resin is insulating material (10-13 S/m), the response is non-linear and ...

A 2nd-generation irradiation target holder is being developed at the High Flux Isotope Reactor (HFIR) of Oak Ridge National Laboratory (ORNL). This 2nd-generation holder design is focused on improving the loading and unloading of the targets by the HFIR operators since a large number of targets are anticipated to be irradiated in the future. Part of the safety analysis required is to ensure ...

The blast furnace hearth drainage constitutes a major part of the blast furnace operation. Especially, keeping track of the iron and slag levels is crucial to adapt the tapping strategy. The operational target is usually not only to empty the blast furnace as far as possible but also to keep the slag below a critical level to prevent flooding of the tuyeres where the hot blast is injected into ...

Utility-scale photovoltaic (PV) and concentrated solar power (CSP) generation facilities are located in desert environments throughout the world to take advantage of the high availability of sunlight in these areas. Unfortunately, naturally occurring sandstorms in these deserts often deposit layers of dust on PV panels and CSP mirrors, reducing the amount of sunlight reaching their surfaces and ...

Greenhouses need heating supply most of the time of a year. Their heating demands are high and economical heating systems are very important for this kind of facilities. Horizontal ground source heat pump systems are getting more interest last years for being easy to apply and low initial cost. However, they need a wide area to apply. In this study, the heating system of a greenhouse is ...

Aluminum alloys in near-neutral, mildly aggressive solutions, undergo damage accumulation during corrosion, mostly due to the presence of micrometer-sized constituent intermetallic particles (IMP) that create a microstructural discontinuity at which localized corrosion occurs. The Nernst-Planck equation with electroneutrality is used to simulate current and pH distributions resulting from ...

Identifying molecules requires associating molecular structures with their electronic energy levels. In this paper we introduce a novel technique for the calculation of molecular Rydberg levels. The technique allows for easy visualization of the associated wavefuntions to make unambiguous assignments. The value calculated for the 3p state of trimethylamine is most closely in agreement with ...

This work is concerned with the study of the asymmetrical phenomenon observed in three-phase transformers during the standard short-circuit test. The purpose of our work is to see if the asymmetric measurements can be predicted with the use of 2D finite-element models. To this end, we use the AC/DC Module of COMSOL Multiphysics. A multi-port network impedance is then determined to explain the ...

The elastic and geometrical properties of Low Density Polyethylene (LDPE) foam are used in this paper to improve the attenuation properties of periodic arrangements of acoustic scatterers known as Sonic Crystals (SCs). A specific recycled profile of LDPE foam is used as elastic-acoustic scatterer. The acoustic spectrum of the single scatterer shows two attenuation peaks in the low frequency ...
