This paper reports on the realization and characterization of the very first quantum-well (QW) mono-crystalline Si/SiGe 18times18 pixel infrared bolometer arrays that are manufactured using IC compatible heterogeneous 3D integration on fan-out wafers. This integration process enables bolometer materials on top of CMOS…
Two planar acetylene-expanded TTFAQ analogues (8a and 8b) were synthesized through a one-pot, 4-fold Sonogashira coupling protocol. The structure and electronic properties of these compounds were investigated by single-crystal X-ray crystallography, UV-vis spectroscopy, and cyclic voltammetry.
An expedient entry into the construction of bionanocomposites by merging peptide self-assembly, focused ion beam milling, and electron beam-induced deposition is described. Hexapeptides 1 and 2 revealed spherical self-assembled structures which are confirmed by a scanning electron microscope (SEM), atomic force micros…
The magnetic, magnetoelectric, and magnetoelastic properties of DyFe 3 (BO 3 ) 4 single crystals and the Nd 0.75 Dy 0.25 Fe 3 (BO 3 ) 4 substituted compound with the competitive Nd-Fe and Dy-Fe exchange interactions have been investigated in magnetic fields up to 210 kOe. It has been shown that the antiferromagnetic s…
Single-walled carbon nanotube (SWCNT) thin-film transistors (TFTs) were fabricated using ink-jet printing. We printed both thick source–drain electrodes and thin active semiconducting films using N , N -dimethylformamide (DMF)-based SWCNT dispersion. Despite the presence of metallic SWCNTs, the device exhibited field-…
Abstract Siloxane coatings were deposited onto Vycor™ glass and silicon substrates from a tetraethyl orthosilicate (TEOS) precursor using the PlasmaStream™ atmospheric plasma jet system. The TEOS precursor was nebulized into He/O 2 plasma and the coating growth rate was controlled by the number of passes of the jet ov…
Triangular-shape OPEs, decorated in their periphery with a variable number of hydrophilic and hydrophobic substituents, have been synthesized to evaluate the influence of the solvent-solute and solute-solute interactions involved in their self-association. The similar size and electronic properties for these radial OP…
A new one pot and solvent-free synthesis of nickel porphyrin complex is described. This is prepared by condensing pyrrole, benzaldehyde, nickel (II) chloride, and 1,8-diazabicyclo [5.4.0] undec-7-ene as a base. This new method allows higher yields, reduced reaction times, ease of handling, and follows principles of gr…
Single and mixed metal oxide/carbon composites like Fe2O3/carbon, Fe2O3-SnO2/carbon, Fe2O3-ZnO/carbon are synthesized by a simple self-propagating solution combustion method. Carbon is introduced in-situ during the preparation of metal oxides in the form of dextrose precursor which act as both fuel and carbon source.…
Metal-free and metallophthalocyanines with four 9-anthroyl groups bound through ethylthio ester bridges on the periphery have been prepared. The new compounds were characterized by elemental analyses, 1 H NMR, IR, mass and UV-vis spectral data. The electronic spectra exhibit an intense π-π* transition of 9-anthroyl id…
We introduce a modulation-doping method to control electrical characteristics of ZnO nanorods. Compared with a conventional homogeneous doping method, the modulation-doping method generates localized doping layers along the circumference in ZnO nanorods, useful for many device applications. Here, we investigated elect…
Citrus fruits are affected by the black spot disease caused by Guignardia citricarpa. Resistance induction is an alternative control measure and chitosan exhibits potential as resistance inducer. The effect of chitosan on G. citricarpa was evaluated in vitro and in 'Valencia' oranges. Citrus fruit were immersed into d…
Although carbon nanotubes (CNTs) are increasingly used, their biological effects are only incompletely characterized. However, experimental evidence suggests that the intratracheal instillation of CNTs causes the formation of interstitial granulomas and progressive pulmonary fibrosis in rodents. Using human epithelial…
The development of vascular grafts requires the matching of material and viscoelastic properties to those of native artery. The hypothesis of this study was to subject electrospun tissue engineering scaffolds composed of polydioxanone, elastin, and collagen to cyclic loading in order to quantify the hysteretic propert…
We have developed a unique approach for studying the ensemble-averaged nearest-neighbor coordination of confined fluids by combining small-angle X-ray scattering and phase-retrieval–based X-ray diffraction from fluid-filled nanofluidic channel arrays. We apply the method to a charge-stabilized quasi–two-dimensional co…
A novel Mg 2 Zr 5 O 12 ‐based coating on magnesium was formed by microarc oxidation (MAO) in a K 2 ZrF 6 ‐containing electrolyte. The structure of the coating was examined by X‐ray diffraction using the grazing angle method, scanning electron microscopy, and transmission electron microscopy. The friction and wear prop…
A perfect matching chart is designed to obtain the matching frequency fm and the matching thickness tm of electromagnetic (EM) attenuation material. Based on the chart, the relationship between matching parameters (fm and tm) and high-frequency dynamic parameters [μ′(f), μ″(f), and ϵ′(f)] are studied for Ni0.97−xZnxCo…
This paper concentrates on the deformation behavior of amorphous diamondlike carbon composite materials. Combined nanoindentation and ex situ cross-sectional transmission electron microscopy investigations are carried out on TiC/a-C nanocomposite films, with and without multilayered structures deposited by pulse dc ma…
The increased consumer demand for high quality, extended shelf life, ready to eat foods has initiated the development of several innovative techniques to keep their natural and fresh appearance as long as possible and at the same time render them safe. Packaging has been an important element in these preservation conc…
Scanning probe microscopy was used to create and to detect local bias induced charged states in La0.89Sr0.11MnO3 single crystals at room temperature. The lifetime of these nonequilibrium states exceeds 100 h. These bias induced states display also a ferroelectriclike hysteresis with piezoelectric contrast reversed by…
