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…

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…
A micromanipulator combined with a microinjection system was employed to inject micro-droplets of aqueous solutions containing redox-active species on selected areas of graphene. Chronoamperometric and voltammetric measurements were performed in order to investigate the diffusion regime established within the micro-dr…
In this paper, new azobenzene imide derivatives with different substituent groups were designed and synthesized. Their gelation behaviors in 21 solvents were tested as novel low-molecular-mass organic gelators. It was shown that the alkyl substituent chains and headgroups of azobenzene residues in gelators played a cr…

PURPOSE: To design, fabricate, characterize, and in vivo assay clinically viable magnetic particles for MRI-based cell tracking. METHODS: Poly(lactide-co-glycolide) (PLGA) encapsulated magnetic nano and microparticles were fabricated. Multiple biologically relevant experiments were performed to assess cell viability,…
Electrochemical processes associated with changes in structure, connectivity or composition typically proceed via new phase nucleation with subsequent growth of nuclei. Understanding and controlling reactions requires the elucidation and control of nucleation mechanisms. However, factors controlling nucleation kinetic…

Abstract We report a method to create a self‐cleaning, transparent surface on poly(methyl methacrylate) (PMMA) using a dry etching with CF 4 plasma and a subsequent hydrolysis process with water immersion. During the CF 4 plasma treatment, nanoscale pillar structures were formed and its aspect ratio tended to increase…
