Proceedings ArticleDOI
3D Electrothermal Simulation of Heterostructure Thin Film Micro-Coolers
Yan Zhang,Daryoosh Vashaee,James Christofferson,Ali Shakouri,Gehong Zeng,Chris LaBounty,Joachim Piprek,Ed T. Croke +7 more
TL;DR: In this paper, a 3D electrothermal model is used to simulate and optimize Si/SiGe superlattice heterostructure micro-coolers, and it is found that the key factor limiting maximum cooling is metal semiconductor contact resistance.
Journal ArticleDOI
Magnon and spin transition contribution in heat capacity of ferromagnetic Cr-doped MnTe: Experimental evidence for a paramagnetic spin-caloritronic effect
TL;DR: In this article, the authors present experimental evidence for the simultaneous existence of the magnons and spin-state transition contributions to the heat capacity in ferromagnetic (FM) Cr-doped MnTe (Tc ∼ 280 K), where the magnon heat capacity is attributed to the observed magnon-bipolar carrier-drag thermopower.
Journal ArticleDOI
Effect of fabrication method on the structure and properties of a nanostructured nickel-free stainless steel
TL;DR: In this paper, an ASTM F2581 nanostructured stainless steel was fabricated by two different powder metallurgy routes; Hot Powder Forging (HPF) and Binder Assisted Extrusion (BAE) methods.
Journal ArticleDOI
Influence of the order of fabrication sequences on the thermoelectric properties of skutterudite CoSb3–Cu0.6Ni0.4 nanocomposites
Ahmad Gharleghi,Mobarak Hossain Polash,Rasoul Malekfar,Sima Aminorroaya Yamini,Daryoosh Vashaee +4 more
TL;DR: In this article, the influence of fabrication processes on the thermoelectric properties of CoSb3 skutterudite was investigated using a grain boundary potential barrier mechanism, which is consistent with the systematic increase of the carrier concentration upon increasing the Cu0.6Ni0.4 content.
Journal ArticleDOI
In vitro analysis of Mg scaffolds coated with polymer/hydrogel/ceramic composite layers
Mostafa Yazdimamaghani,Mehdi Razavi,Mehdi Razavi,Daryoosh Vashaee,Venkata Raveendra Pothineni,Senait Assefa,Gerwald A. Köhler,Jayakumar Rajadas,Lobat Tayebi,Lobat Tayebi +9 more
TL;DR: Results show that the coated scaffold can keep its mechanical integrity three times longer than the uncoated one, and cell viability and growth are acceptable on the Mg scaffold/PCL–BaG/Gel– BaG.
