We report on the synthesis of ferromagnetic manganese arsenide (MnAs) nanoparticles via the conversion of primary Mn particles which are generated in an aerosol process in a spark discharge generator. After sintering and size selection in an aerosol setup, the particles are deposited on GaAs(100)B and Si(111) substrat…
Ternary hybrid film composed of a-zirconium phosphate nanosheet, 1,2-bis(dimethylchlorosilyl)ethane and polypyrrole was prepared by anodic electrodeposition. In the hybrid film, ordered a-zirconium nanosheets with grafts by silylation lay down parallel to the substrate and the polypyrrole molecules were intercalated b…
A study on the effect of silver-filled electrical epoxy materials and the effect of electroless silver nitrate-plated woven fabrics on electromagnetic shielding effectiveness of various woven fabrics has been reported. Polyester, cotton, polyester/viscose blend, and polyester/cotton blend fabrics were treated with sil…
The unbeaten path is where discoveries of great ideas can be found. Introduction In contemporary fundamental and applied science research, the potential applications and the perceived broader impacts are undoubtedly the primary drivers for expanding the research enterprise. This has certainly been the case for nanotub…
Three types of compounds (Li 5 TiN 3, Li 5 TiN 3 (NH 3 ) x, and TiCl 3 (NH 3 ) x ) were synthesized as possible catalysts in the Li−N−H system, and their catalytic effects on hydrogen desorption performance were examined. The three types of compounds exhibited a catalytic effect in the Li−N−H system. The XRD results a…
Abstract Piassava ( Attalea funifera ) fibers subjected to several surface chemical treatments and as‐received raw fibers were compared with respect to their thermal and tensile behaviors. The thermal degradation of the raw fibers was characterized by three main stages that corresponded to water release at low tempera…
Corrosion has been frequently recognized as failure's root cause for diverse engineering components like those associated to production lines, like in boiling water reactor piping systems (1). It is important that several electrochemical techniques help conjointly to elucidate some of the corrosion specificities, like…
Microporous polymer films prepared by templating “breath figures” tend to have closely packed, hexagonal arrays of pores. We characterize the hexagonal order of the structured films using Fraunhofer diffraction patterns in reciprocal space, as well as with the use of Voronoi diagrams and bond-orientational correlation…
Sr1−x Pr x Fe12 − x Zn x O19 ferrites with x = 0, 0.1, 0.2, 0.3, 0.4, and 0.5 have been prepared by solid-state reactions between praseodymium, iron, and zinc oxides and strontium carbonate in air at 1470 K. According to X-ray diffraction results, the samples with x ≤ 0.2 were single-phase and those with 0.3 ≤ x ≤ 0.5…
The thermodynamics of vaporization in the Bi 2 O 3 -Fe 2 O 3 quasibinary system was studied by high-temperature mass-spectrometry. The partial pressures of the constituents of a saturated vapor over the system at 1100 K were determined. Based on the experimental data, the following parameters were calculated: the acti…
Developing a low-cost, simple manufacturing process for highly efficient thermoelectric films is an intriguing topic for both chemists and materialists. In this work, a new strategy was introduced to synthesize bismuth chalcogenide films by chemical vapor transport on presynthesized Bi films, including Bi2Se3, Bi2Te3…
Abstract The dependence of peel strength and shear strength of epoxidized natural rubber (ENR‐50)‐based pressure sensitive adhesive on molecular weight and rate of testing was investigated using coumarone‐indene as the tackifying resin. Toluene and polyethylene terephthalate were used as the solvent and substrate resp…
The variation of visible and IR absorption spectra and of small-angle X-ray scattering of poly(3-octylpyrrole)squaraine in trichloromethane solution indicates that, for this zwitterionic conducting polymer (CP), a reversible change of conformation is induced by contact of the solution with the surface of an active met…
The idea that cancer is not one but many diseases has completely changed the oncology landscape and promoted the development of personalized cancer therapy. Based on a better understanding of the mechanisms of cancer cell proliferation and tumor growth, novel therapies have emerged to address unmet medical needs and e…
Abstract Polylactide (PLA) is a bio‐based, biodegradable polymer, which is derived from lactic acid and has numerous potential applications, some of which are limited by its moisture barrier and thermal properties. Prior studies have been inconsistent about how moisture sorption in PLA varies with crystallinity and mo…
We present the design, fabrication, and characterization of vertical assembly of 3-D single-walled carbon nanotubes (SWNTs) thermal sensors. Carbon nanotubes (CNT) were deposited utilizing dielectrophoretic (DEP) assembly technique with a 98.7% yield. The scanning electron micrograph images revealed that by adjusting…

Abstract BACKGROUND: Cytisus scoparius samples were processed with hot, compressed water (autohydrolysis treatments) to obtain both fiber‐containing solids (suitable as reinforcements for composites) and a liquid phase containing sugar oligomers derived from hemicelluloses. The solid phase from autohydrolysis, mainly…
Patterning of organic compounds on a nanometer length scale is of great interest for solar applications: defined control over the donor-acceptor interface will allow design of an optimized nano-morphology promoting exciton separation and reducing charge recombination. Herein we present an imprinting technique using an…
Conjugated self-assembled systems in water are of great interest because of their potential application in biocompatible supramolecular electronics, but so far their supramolecular chemistry remains almost unexplored.
