We propose plasmonic metal-insulator-metal (MIM) metamaterial designs for the sensing of two infrared wavelength bands, the mid-wavelength infrared (MWIR) and long-wavelength infrared (LWIR) band by using a photon sorting technique. The proposed structures can capture light effectively on the metasurfaces based on cou…
The aim of this study was to explore the development of lead-free X-ray shielding rubber nanocomposites with improved mechanical properties. In specific, gadolinium oxide (Gd 2 O 3 ) nano-flakes (with thickness of ∼20 nm and sizes being tens of nanometers) were first prepared via the co-precipitation spray drying meth…
By making a systematic study of the hydrogen-doped LaFeAsO system by means of dc resistivity, dc magnetometry, and muon-spin spectroscopy, we addressed the question of universality of the phase diagram of rare-earth-1111 pnictides. In many respects, the behaviour of LaFeAsO(1-x)H(x) resembles that of its widely studie…
The development of organic polymers with low infrared absorption has been investigated as a possible alternative to inorganic metal oxide, semiconductor, or chalcogenide-based materials for a variety of optical devices and components, such as lenses, goggles, thermal imaging cameras and optical fibers. In principle, o…
The assembly of Au nanorods of average size 14 × 42 nm was investigated by electric field assisted deposition. The nanorods displayed a rich assembly behavior with formation of one dimensional (1D) architectures under specific experimental conditions. The assembly process was found to be dependent on both the intensit…
Tantalum oxide (Ta 2 O 5 ) thin films were prepared, at different deposition time, by a DC reactive magnetron sputtering. During the deposition, a high-quality tantalum target was sputtered under argon and oxygen ambience on to silicon (100) and glass substrates. The prepared thin films were systematically characteriz…
The relationship between property and structure is one of the most important fundamental questions in the field of nanomaterials and nanodevices. Understanding the multiproperties of a given nano-object also aids in the development of novel nanomaterials and nanodevices. In this paper, we develop for the first time a…
Ab initio Hartree–Fock (HF) and Density Functional Theory (DFT) B3LYP methods with the 6-311G(d,p) basis set were applied to the three 11-thiocyanatoundecanoic acid phenylamide derivatives as corrosion inhibitors. Inhibition efficiency obtained experimentally followed the following order: N-(4-methoxyphenyl)-11-thiocy…
Despite the use of petrochemical derived packaging, many problems such as browning and food spoilage still happen in food after harvesting. There is an increasing consumers concern for food shelf life to be extended as much as possible along with a big interest in green and bioactive materials, that could be used in d…
Abstract A dynamic‐covalent metal‐containing polymer was synthesized by the condensation of linear diamine and dialdehyde subcomponents around copper(I) templates in the presence of bidentate phosphine ligands. In solution, the red polymers undergo a sol–gel transition upon heating to form a yellow gel, a process that…
Abstract We present a study of the influence of the iodine/solvent annealing temperature on the properties of piezoresistive bilayer films with layers of α‐(BEDT‐TTF) 2 I 3 [BEDT‐TTF = bis(ethylenedithio)tetrathiafulvalene]. The formation of the conductive layers was tested by XRD, direct current (dc) conductivity mea…
We predict three new polymorphs of boron by applying density functional theory (PBE flavor) to large shear deformations starting from the recently discovered γ-B 28 boron phase (stable above 9 GPa and 1000 K). We find that continuous deformation along the (100)/⟨001⟩ slip system leads to two new phases, named here as…
Small-angle bent-core liquid-crystalline (LC) molecules based on a 1,2-bis(phenylethynyl)benzene central core have been synthesized that form banana smectic phases with a ferroelectric B7-antiferroelectric B2 phase sequence upon cooling. The formation of polar, switchable ferro-/antiferroelectric banana phases indicat…
We have studied the electronic structure of nitinol exposed to low-energy oxygen-ion bombardment, using x-ray photoemission spectroscopy (XPS) and near-edge x-ray absorption fine structure (NEXAFS) spectroscopy. XPS spectra reveal a gradual transformation of nitinol surfaces into TiO2 with increased dose of implanted…
Magnetite (Fe 3 O 4 ) nanoparticles were successfully synthesized by the sol-gel method from ferric nitrate-EG (EG=ethylene glycol) gel. The precursors were calcined in argon under an atmospheric pressure at the temperatures varied from 400°C to 500°C. The synthesized magnetic nanoparticles were characterized by X-ray…
Abstract A series of highly efficient semiconductor nanocrystal (NC) photocatalysts have been synthesized by growing wurtzite‐ZnO tetrahedrons around pre‐formed CdS, CdSe, and CdTe quantum dots (QDs). The resulting contact between two small but high‐quality crystals creates novel CdX/ZnO heterostructured semiconductor…
Abstract A collagen‐mimetic peptide, NSIII, has been designed with three sequential blocks having positive, neutral, and negative charges, respectively. The non‐canonical imino acid, (2 S ,4 S )‐4‐aminoproline (amp), was used to specify the positive charges at the Xaa positions of (Xaa‐Yaa‐Gly) triads in the N‐termina…
We have detected the surface-enhanced Raman scattering (SERS) signals of toluene and 1,2-dichlorobenzene (ODCB) vapors at parts per million concentrations using 1-propanethiol-linked Ag nanoparticles and a fiber optics–coupled Raman spectrograph. Calibration curves were constructed for each detector by plotting Raman…
Regenerable polyelectrolyte multilayers (PEMs) are prepared on the basis of a sacrificial block of polyelectrolyte on the top of a non‐removable PEM. Poly(allylamine hydrochloride) (PAH) and polyestyrene sulfonate (PSS) PEMs with a block of poly(diallylmethylammonium chloride) (PDADMAC)/PSS on top; PAH/PSS with PDADM…
Quaterthiophene (QT) with a 1,2,3-triazole moiety was found to have a high sensory response in solution toward a broad class of nitroaromatics, including DNT and TNT, and nitro esters, such as RDX and PETN. Fluorescence quenching in QT thin films was also high for vapors containing DNT or TNT in ppb levels. These resu…
