Additive manufacturing (AM), widely known as 3D printing, is a method of that forms parts from powder, wire or sheets in process proceeds layer by layer. Many techniques (using many different names) have been developed to accomplish this via melting solid-state joining. In review, these for producing metal are explored, with focus on the science AM: processing defects, heat transfer, solidification, precipitation, mechanical properties and post-processing metallurgy. The various AM compared,...
Abstract Starting from a kinetic theory based two‐fluid model for gas‐particle flows, we first construct filtered equations that average over small scale inhomogeneities do not wish to resolve in numerical simulations. We then outline procedure extract constitutive models these through highly resolved simulations of the periodic domains. Two‐ and three‐dimensional show closure relations manifest definite systematic dependence on filter size. Linear stability analysis reveals filtering does...
The electrochemical rate performance and capacity retention of the "layered–layered" lithium rich Li1.2Mn0.525Ni0.175Co0.1O2 (Li-rich NMC) material are significantly improved by a nanometer layer coating conducting solid electrolyte, phosphorus oxynitride (LiPON). LiPON is deposited on Li-rich NMC particles RF-magnetron sputtering method. presence provides interfacial stability under high current (rate) voltage cycling conditions thereby improves over cycle life compared to pristine or...
Abstract Silicon (Si) is under consideration as a potential next-generation anode material for the lithium ion battery (LIB). Experimental reports of up to 40% increase in energy density Si based LIBs (Si-LIBs) have been reported literature. However, this achieved when Si-LIB allowed swell (volumetrically expand) more than graphite LIB (graphite-LIB) and beyond practical limits. The volume expansion electrodes should be negligible applications such automotive or mobile devices. We determine...
In our prior studies ([Igci, Y.,, AIChE J., 2008, 54, 1431−1448] and [Igci, Y.,Sundaresan, S., 2010, in press]) we presented a methodology where computational results obtained through highly resolved simulations of given microscopic two-fluid model (TFM) for gas-particle flows are filtered to deduce constitutive models the residual correlations appearing corresponding TFM equations that appropriate coarse-grid flows. We had also analyzed flow behavior vicinity solid boundaries proposed wall...
Using neutron tomographic imaging, we report for the first time three-dimensional spatial distribution of lithium products in electrochemically discharged lithium-air cathodes. Neutron imaging finds a nonuniform product across electrode thickness, with species concentration being higher near edges Li-air and relatively uniform center electrode. The experimental images were analyzed context results obtained from 3D modeling that maps spatiotemporal variation using kinetically coupled...
Recent advancements in high-performance parallel computing platforms and algorithms have significantly enhanced the opportunities for real-time power system protection control.

Time-parallel face difficulty providing correct initial conditions all impact convergence rates. overcomes this by...
We demonstrate the lithiation process in graphitic anodes using situ neutron radiography and diffraction a single-layer pouch cell. The variation absorption contrast graphite shows direct correlation between degree of discharge potential. experimental attenuation line profiles across electrode at various times (potentials) were compared with lithium concentration computed 3D electrochemical transport model. In conjunction imaging/radiography, was carried out to obtain information about local...
Lithium-ion batteries are highly complex electrochemical systems whose performance and safety governed by coupled nonlinear electrochemical-electrical-thermal-mechanical processes over a range of spatiotemporal scales.
