Carbon nanotubes offer exciting opportunities for devising highly-sensitive detectors of specific molecules in biology and the environment. Detection limits as low as 10(-11) M have already been achieved using nanotube-based sensors. We propose the design of a biosensor comprised of functionalized carbon nanotube pore…
The photocontrolled phase transitions and reflection behaviors of a smectic liquid crystal, 4-octyl-4'-cyanobiphenyl (8CB), tuned by a chiral azobenzene, are systematically investigated. For the smectic 8CB doped with the chiral azobenzene (1R)-(-)-4-n-hexyl-4'-menthylazobenzene (ABE), the initial smectic phase can be…
Well-defined finite particles of nitrate forms of layered double hydroxides (MgAl and NiAl types) were successfully synthesized from aqueous solution of metal nitrates by the recently developed pH adjustment method, where hydroxide form ion-exchange resin was used to change a starting acidic solution into basic soluti…
The biocomposites of poly(3-hydroxybutyrate- co -4-hydroxybutyrate) [P(3,4HB)] and recycled carbon fiber (RCF) were prepared via a melting extrusion. The crystallization behaviors and kinetics of the P(3,4HB) matrix in composites were exclusively studied under both nonisothermal and isothermal conditions. The correspo…
Theoretical calculations have been performed in the framework of density functional theory to characterize the effect of axial deformation on hydrogen storage of Ti decorated armchair (5,5) SWCNT. The theoretical characterization has been carried out in terms of H2 adsorption energies that are lying in the desirable e…
A thermoelectric generation system (TEGS) used in the practical industry of waste heat recovery consists of the fluidic heat sources, the external load circuitry, and many thermoelectric modules (TEMs) connected as a battery bank. In this paper, a system-level model is proposed to seamlessly integrate the complete flu…
This paper presents findings from an ongoing research study aimed at increasing the available sustainable construction materials that could possibly be used in the design and construction of civil infrastructure and commercial building projects in the future. At the Sustainable Material and Renewable Technology Labora…
Abstract We report on optically pumped lasing from a vapor‐grown crystal of thiophene/phenylene co‐oligomer, 2,5‐bis(4′‐methoxybiphenyl‐4‐yl)thiophene (BP1T‐OMe). By using a pair of parallel facets of a thin sword‐like crystal as a Fabry–Pérot resonator, laser oscillations were obtained in the 0‐2 emission wavelength…
The effective parallel and perpendicular dielectric constants for a multilayer metal–insulator stack are obtained from numerical simulations and compared with analytical homogenization results as a function of wavelength and number of periods. The influence of inevitable film surface roughness on the homogenized diele…
A structure analysis of the Preisach model in a variational setting is carried outby means of an auxiliary hyperbolic equation with memory variable playing the role of time,and amplitude of cycles as spatial variable. Using this representation, wepropose an algorithm and derive error estimates for the identification o…
Mechanical properties of tibial bone at compressive strain rates of 50–200/s are obtained through a Split Hopkinson pressure bar. Cylindrical specimens of 12–15 mm diameter and 2–5 mm thickness were prepared. The Young's moduli are calculated from linear portion of stress–strain curves. For both cortical and cancellou…
A large variety of applications ranging from plasmonic sensing to plasmonic enhanced solar cells, photonics, and optics can benefit from a reliable method to enhance chemical and time stability of silver-based plasmonic nanostructures and metamaterials. Therefore, here we demonstrate and discuss the effectiveness of a…
Foam granulation technology is a new wet granulation approach for pharmaceutical formulations. This study evaluates the performance of foam and spray granulation in achieving uniform drug distribution using a model formulation. To observe wetting and nuclei formation, single drop/foam penetration experiments were perf…
Abstract This study synthesized a series of titanium iminophenoxide complexes and investigated their suitability as catalysts for the ring‐opening polymerization of L‐lactide (L‐LA) and ε‐caprolactone (CL). Complexes with bidentate ligands demonstrate higher catalytic activity than their tridentate counterparts since…
A group of bioactive steroidal glycosides (pregnanes) with anorectic activity in animals was isolated from several genera of milkweeds including Hoodia and Asclepias. In this study, we investigated the effects, structure-activity relationships, and mechanism of action of pregnane glycosides on steroidogenesis in human…
We present the fabrication of Ni nanocone arrays on Ni foil substrate as well as gas exposure field electron emission experiments using them as cold electron cathodes. The self-assembly of nanoscale building blocks into organized conical superstructures is achieved by the assistance of oriented attachment. These Ni na…
Substitutions of trans-Na(Him)[Mo(2)O(4)(ox)(2)(H(2)O)(2)]·H(2)O (1) and trans-(Him)(2)[Mo(2)O(4)(ox)(2)(H(2)O)(2)] (2) with imidazole result in the formation of the mixed-ligand molybdenum complexes cis-Na(2)[Mo(2)O(4)(ox)(2)(im)(2)]·4.5H(2)O (3), cis-K(2)[Mo(2)O(4)(ox)(2)(im)(2)]·3H(2)O (4), respectively (H(2)ox = o…
Because of their unique anisotropic characteristics, Janus particles have been assessed as attractive building blocks for self-assembly with desirable supramolecular architectures, leading to the creation of novel functional materials.1–5 Janus particles with tunable chemistry and physical propertie...
CdSe quantum dots (QDs) were attached to the surfaces of nanocrystalline TiO(2) films functionalized with 16-mercaptohexadecanoic acid (MHDA). The solvent from which MHDA was adsorbed to TiO(2) determined the amount of adsorbed MHDA, the extent of ordering within monolayers, and the lability of MHDA-TiO(2) interaction…
The tite compound, lithium penta-sodium nona-molybdate, LiNa(5)Mo(9)O(30), was synthesized by solid-state reaction. The three-dimensional [Mo(9)O(30)](6-) framework is built up from MoO(6) octa-hedra and MoO(5) bipyramids, linked together by edges and corners. The framework delimits two types of inter-secting tunnels…
