Second harmonic generation contrasts of ferroelectric domain structures and composition in lithium niobate–tantalate mixed crystals
Lithium niobate–tantalate mixed (LNT) crystals promise improved performance and new applications for optical, piezomechanical, or electrical devices when compared to the end composition compounds lith...
Study on the heat transfer characteristics of MWCNTs and Ni-MWCNTs nanofluids based on the 3<i>ω</i> method
Compared to pure multi-walled carbon nanotube (MWCNT) nanoparticles, metal-modified MWCNT nanoparticles might have better thermal conductivity. We prepared 10# transformer oil (TO)/MWCNT, ethylene gly...
Non-local spin-transport structures and governing length-scales
Non-local spin-current conduction can serve to concentrate spin-current in a nanostructure in spin-torque switchable nanomagnets in solid-state memory. This is sometimes called spin-harvesting or spin...
CBRAM based on CVD-grown MoSe2 with the coexistence of volatile and non-volatile resistive switching
Nonvolatile memory based on conductive bridge random access memory or memristors is widely considered as a candidate for next generation memory devices for artificial intelligence. Two-dimensional (2D...
A molecular dynamics study of single crystal and intergranular crack growth behavior in W<i>x</i>M1−<i>x</i> binary alloys (M = V, Mo, Ta, Re)
This study employs molecular dynamics simulations to investigate the fracture behavior of four binary refractory alloys WxM1−x (M = V, Mo, Ta, Re) and their dependence on crystallographic orientation,...
Giant magnetocaloric effect of divalent europium-based oxide composites of Eu2TiO4 and Eu3Ti2O7 for cryogenic temperature magnetic refrigeration
For cryogenic temperature magnetic refrigeration, we focused on materials containing Eu2+ ions and synthesized sintered composite materials comprising Eu2TiO4 and Eu3Ti2O7. Eu3Ti2O7 and Eu2TiO4 exhibi...

Enhanced saturable absorption induced by Pauli blocking and radiation-induced trapping with negative photoresponse in Cr2O3/MoS2/PEDOT:PSS
We have successfully shown a method to considerably modify the nonlinear saturable absorption characteristics of nanocomposite films (NCFs) composed of poly(3,4-ethylenedioxythiophene) doped with poly...
Tunable optical switching via magnetostatic field modulation in a small-radius hyperbolic metamaterial bent waveguide at THz frequencies
A bent waveguide (BWG) made of hyperbolic material (such as indium arsenide) is designed to enable optical switching and modulation. The BWG comprises two straight waveguides and a 90o bent section, e...
Spall strength of symmetric tilt grain boundaries in 6H silicon carbide
Characterizing microstructural effects on the dynamical response of materials is challenging due to the extreme conditions and the short timescales involved. For example, little is known about how gra...
