A Cost-Effective Optical Device for the Characterization of Liquid Crystals
The design and construction of an apparatus to measure the optical birefringence of a liquid crystal is described. The instrument also includes temperature control and monitoring circuitry to allow for the measurement of the nematic-to-isotropic phase transition temperature. An important feature of this design is that…
A 3-D Stackable Maskless Embedded Metal-Gate Thin-Film-Transistor Nanowire for Use in Bioelectronic Probing
Using a self-aligned sidewall microcrystalline-silicon (μc-Si) dual channel, comprising a sub-50-nm channel width, a novel 3-D stackable maskless embedded metal-gate thin-film-transistor nanowire device was fabricated on top metal using a tungsten gate-stack and trilayered oxide/nitride/oxide gate dielectric. The resu…

ChemInform Abstract: Syntheses, Structures, and Electronic Properties of a New Series of Tellurides of the Type [Sequestered Cation]2(Tex) (x = 1—4).
Abstract The structures of the tellurides (III) (monoclinic, space groups P21/c, Z = 4), (IV) (P21/n, Z = 4), and (V) (C2/c, Z = 8), (VII) (C2/c, Z = 4), (VIII) (P21/c, Z = 4), (IX) (P21/c, Z = 4), and (X) (trigonal, R$\bar 3$ , Z = 3) are determined by single crystal XRD.
Robust acoustic cloaking with density-near-zero materials
Using the phenomenon of extraordinary sound transmission (EST) through artificially constructed density-near-zero (DNZ) materials, we propose an alternative approach to realize a very robust acoustic cloaking, which includes one absorber and one projector connected by an energy channel. The elementary unit cell is mad…
Contribution of elastic photoelectron scattering to the shape of the measured XPS intensity in‐depth profile
The in‐depth profiles obtained from Auger electron spectroscopy or X‐ray photoelectron spectroscopy (XPS) experiments are known to differ from an actual concentration profiles due to limitations of surface‐sensitive techniques, e.g. finite sampling depth, or atomic mixing during sputtering. However, the monitored sign…
Signatures of dynamic heterogeneity from a generalized hydrodynamic model of the supercooled liquid
In this paper we study the four point correlation function $χ_4$ of collective density fluctuations in a nonequilibrium liquid. The equilibration is controlled by a modified stretched exponential behavior ( $\exp [-{(t_\mathrm{w}/τ)}^β]$ ) having the relaxation time $τ$ dependent on the aging time $t_\mathrm{w}$. Simi…
DETERMINING THE FUNCTION OF HOTDOG-FOLD THIOESTERASES
The enzymes that hydrolyze thioesters to the free acids and free thiols are called thioesterases. Based on the different folding strategy, most thioesterases are classified into two superfamiles: the hotdog-fold enzyme superfamily or alpha/beta-fold hydrolase enzyme superfamily. Hotdog-fold thioesterases share high de…
2-((E)-{4-[Bis(4-ethoxyphenyl)amino]phenyl}iminomethyl)phenol
In the title Schiff base mol-ecule, C29H28N2O3, the three terminal benzene rings are twisted by 73.84 (15), 81.25 (16) and 12.1 (2)° with respect to the central benzene ring. An intra-molecular O-H⋯N hydrogen bond occurs. In the crystal, mol-ecules are linked via weak C-H⋯π inter-actions into a three-dimensional supra…
Increase of the load carrying capacity of aluminum 2024-T3 by means of a NiP-CrC-DLC coating
The present investigation has been conducted in order to evaluate the tribological behavior of an AA2024-T3 aluminum alloy, coated with a NiP-CrC-DLC coating.
