Fe50Co50-Hf films were deposited on the (011)-cut single crystal lead zinc niobate–lead titanate (PZN-PT) substrates by a composition gradient sputtering (CGS) method. Strong converse magnetoelectric (ME) coupling was observed in the multiferroic laminates of CGS Fe50Co50-Hf/PZN-PT, which exhibited a large electric fi…
This paper focuses on the energy absorbing characteristics and progressive deformation behavior of woven jute-polyester composite cylindrical tubes subjected to an axial impact load. In this study, the impact energy absorption characteristics and crushing mechanisms of composite tubes of different thicknesses and numb…
In-line hydrocarbon (HC) traps are not widely used to reduce HC emissions due to their limited durability, high platinum group metal (PGM) concentrations, complicated processing, and insufficient hydrocarbon (HC) retention temperatures required for efficient conversion by the three-way catalyst component. New trapping…
A straightforward method to prepare nonionic polymer (polyacrylamide, PAM) cross-linked chitosan hydrogel has been developed. The chitosan-polyacrylamide (CS-PAM) hydrogel could be quickly obtained by simply mixing of chitosan and polyacrylamide solutions under very benign condition (room temperature, <30 s). The cyto…
Increasingly stringent targets on energy efficiency and emissions, as well as growing vehicle electrification are making attractive the electric recovery of the energy normally wasted through the tailpipe of Internal Combustion Engines. Recent developments in thermoelectrics (TE) may soon make them a viable solution f…
Spatial localization of the oxygen reduction/evolution reactions on lanthanum strontium cobaltite (LSCO) surfaces with perovskite and layered perovskite structures is studied at the sub-10 nm level. Comparison between electrochemical strain microscopy (ESM) and structural imaging by scanning transmission electron micr…
We made clean silver nano-clusters (AgNCs) on glass substrates by DC magnetron sputtering of a high purity Ag target in a high vacuum chamber. The AgNCs film shows strong localized surface plasmon resonance (LSPR) due to the coupling among Ag nanoparticles in the AgNCs and the coupling between AgNCs. The LSPR indicate…
Sb3+/Mn2+ co-doped phosphate glasses were prepared by high temperature melting method. The absorption, excitation, and emission spectra of the glasses were investigated. The glasses are transparent in the visible light region and can emit strong red light under 275, 360, 415, or 520 nm excitation. Under 275 nm excitat…
Liquid crystalline (LC) mixtures of cholesteryl oleyl carbonate (COC) and 4-pentyl-4'-cyanobiphenyl (5CB) as well as dispersions of single-walled carbon nanotubes (NTs) in these mixtures were studied by means of selective reflection measurements, differential scanning calorimetry (DSC) and optical microscopy. The rela…
In order to meet the clinical application requirements of biodegradable materials in orthopedic surgery field, novel Mg–3Zn–0.5Zr/ xHA ( x = 0, 0.5, 1 and 1.5 wt%) composites have been developed by melting under the mechanical stirring and the heat extrusion route. The thorough examination on the effect of nano-hydrox…
ZnO nanorod arrays (NRAs) on transparent conductive oxide (TCO) films have been grown by a solution-free, catalyst-free, vapor-phase synthesis method at 600°C. TCO films, Al-doped ZnO films, were deposited on quartz substrates by magnetron sputtering. In order to study the effect of the growth duration on the morpholo…
Ba0.5Sr0.5TiO3 (BST50)/MgO composites, with 2-2-type configurations, consisting of BST layers and MgO layers, were fabricated by using tape-casting and laminating technique. Microstructure, dielectric response, and tunable properties of the 2-2-type composites were investigated. An important feature of the 2-2 type co…
The experimental determination of valence band offsets (VBOs) at interfaces in complex-oxide heterostructures using conventional soft x-ray photoelectron spectroscopy (SXPS, hν ≤ 1500 eV) and reference core-level binding energies can present challenges because of surface charging when photoelectrons are emitted and in…
We report preclinical proof of principle for effective treatment of B-precursor acute lymphoblastic leukemia (ALL) by targeting the spleen tyrosine kinase (SYK)-dependent antiapoptotic blast cell survival machinery with a unique nanoscale pharmaceutical composition. This nanoscale liposomal formulation (NLF) contains…
We report that a spontaneous strain glass to martensite (STG-M) transition occurs in a Ni45Co10Mn20Ga25 ferromagnetic strain glass. The signatures of the spontaneous STG-M transition of Ni45Co10Mn20Ga25 ferromagnetic strain glass are stronger than those of Ti50Ni44.5Fe5.5 strain glass reported previously. Such a diffe…
Temperature effects on the deformation and fracture of a commercially produced transformation-induced plasticity (TRIP) steel subject to a two-step quenching and partitioning (Q&P) heat treatment are investigated. Strain field evolution at room temperature is quantified in this 980 MPa grade Q&P steel with a stereo di…
In order to study the fundamental conduction mechanism of LaAlO3/SrTiO3 (LAO/STO) interfaces, heterostructures were modified with a single unit cell interface layer of either an isovalent titanate ATiO3 (A = Ca, Sr, Sn, Ba) or a rare earth modified Sr0.5RE0.5TiO3 (RE = La, Nd, Sm, Dy) between the LAO and the STO. A st…
Abstract Halite scale has long been a challenge in the oil and gas industry. In recent years there has been a marked increase in the occurrence of this scale type due to the increased development of hotter and deeper gas and gas condensate fields. As the formation of this scale is commonly in the downhole production t…
Thin-films of copper oxide$({\hbox{Cu}}_{x}{\hbox{O}})$were produced by thermal oxidation of metallic copper (Cu) at different temperatures (150–450$\ ^{\circ}{\hbox{C}}$). The films produced at temperatures of 200, 250 and 300$\ ^{\circ}{\hbox{C}}$showed high Hall motilities of 2.2, 1.9 and 1.6${\hbox{cm}}^{2}\ {\hbo…
UreG proteins are small GTP binding (G) proteins that catalyze the hydrolysis of GTP necessary for the maturation of urease, a virulence factor in bacterial pathogenesis. UreG proteins are the first documented cases of intrinsically disordered enzymes. The comprehension of the dynamics of folding-unfolding events occu…
