We consider a simple model of a quasi-one-dimensional conductor in which two order parameters (OP) may coexist, i.e., the superconducting OP $\ensuremath{\Delta}$ and the OP $W$ that characterize the amplitude of a charge-density wave (CDW). In the mean field approximation, we present equations for the matrix Green's…
By using metallo-hydrogel as a new platform, a simple and straightforward selective visual discrimination of cysteine, homocysteine and glutathione from each other as well as from other amino acids has been realized.
Nitric oxide (NO) and reactive oxygen species (ROS) production was investigated in the marine diatom, Skeletonema marinoi (SM), exposed to 2E,4E/Z-decadienal (DECA), 2E,4E/Z-octadienal (OCTA), 2E,4E/Z-heptadienal (HEPTA) and a mix of these last two (MIX). When exposed to polyunsaturated aldehydes (PUA), a decrease of…
We synthesize an iron-doped PbTe single-crystal ingot and investigate the phase and the elemental composition as well as galvanomagnetic properties in weak magnetic fields (4.2 K≤T≤300 K, B ≤ 0.07 T) of Pb1−yFeyTe alloys upon varying the iron content, at atmospheric pressure and under hydrostatic compression up to 10…
The photochemical behaviour of functionalised gold nanoparticles (AuNPs) carrying azobenzenethiolate-alkylthiolate monolayers was investigated. Repeated trans-cis and cis-trans isomerisation cycles could be performed in all cases with high efficiency. Reversible photoinduced aggregation was observed when azothiolates…
To enhance the crystallization kinetics of poly(lactic acid) (PLA), fibrous sepiolite was explored for nucleating the crystallization of PLA. PLA/sepiolite nanocomposites were prepared via the melt‐extrusion method. The effect of sepiolite on the crystallization behavior, spherulite growth and crystal structure of PLA…
Abstract One-dimensional (1D) boron nitride nanotube (BNNT) and 2D hexagonal BN (h-BN) are attractive for demonstrating fundamental physics and promising applications in nano-/microscale devices. However, there is a high anisotropy associated with these BN allotropes as their excellent properties are either along the…
Three copper-azido complexes [Cu 4 (N 3 ) 8 (L 1 ) 2 (MeOH) 2 ] n ( 1 ), [Cu 4 (N 3 ) 8 (L 1 ) 2 ] ( 2 ), and [Cu 5 (N 3 ) 10 (L 1 ) 2 ] n ( 3 ) [L 1 is the imine resulting from the condensation of pyridine-2-carboxaldehyde with 2-(2-pyridyl)ethylamine] have been synthesized using lower molar equivalents of the Schiff…
Superhydrophobic surfaces have been extensively investigated for self‐cleaning, low‐adhesion, anti‐corrosion or reduced‐drag applications. Roughness and its characteristics, i.e., morphology, overall roughness and individual feature size, is an essential factor for superhydrophobicity. Several experimental methods and…
Mesoporous silica nanoparticles (MSNPs) have been widely used as drug carriers for stimuli-responsive drug delivery. Herein, a catalysis screening technique was adopted for analyzing the effects of chain length, terminal group, and density of disulfide-appended functional ligands on the surface of MSNPs on drug-loadin…
Several processes in textile finishing involve a modification on fabric sensorial and mechanical properties. This paper tries to evaluate the effect of four different washes on the denim fabric tactile properties using a sensory analysis. The studied washes were rinse, stone1, stone2 and stone bleach. The tactile sens…
The nature of interaction and mechanism of internalization of receptor-avid peptide nanoparticles with cells is not yet completely understood. This article describes the cellular internalization mechanism and intracellular trafficking of peptide conjugated receptor targeted porous Gold nanocages (AuNCs) in cancer cell…
SrAl 2 O 4 :Eu 2+ ,Dy 3+ phosphors can convert near ultraviolet light with lower sensitivity to the solar cell to yellow‐green light at which the solar cell has higher sensitivity and exhibit the excellent luminescent property of long persistence. Therefore, in this study, the authors firstly synthesized the fine SrAl…
Cerium doped SnO2 hollow nanofibers were synthesized by electrospinning. High resolution scanning electron microscope (HRSEM) and transmission electron microscopy (TEM) analysis showed hollow nanofibers with diameters around ∼200 nm. The optimized substitution of Ce ion into SnO2 lattices happened above 6 mol. % dopin…
Chemical vapor deposited monolayer graphene is transferred onto atomically flat and ultra-thin muscovite mica to study the transport characteristics of graphene with a test structure of mica-based graphene field effect transistor (GFET). The transfer curve of the 24 nm mica-based GFET shows an effective carrier mobili…
${\mathrm{Sr}}_{3}{\mathrm{Ir}}_{4}{\mathrm{Sn}}_{13}$ is an interesting compound showing the coexistence of structural phase transition and superconductivity. The structural phase transition at 147 K leads to the formation of a superlattice. We perform optical spectroscopy measurements across the structural phase tra…
In this paper, we demonstrate the seeded growth of graphene under a plasma chemical vapor deposition condition. First, we fabricate graphene nanopowders (~5 nm) by ball-milling commercial multi-wall carbon nanotubes. The graphene nanoparticles were subsequently subject to a direct current plasma generated in a 100 Tor…
In this Letter, a bilaminate acoustic cloak designed using scattering cancellation methods is applied to the case of an acoustic sensor consisting of a hollow piezoelectric shell with mechanical absorption. The bilaminate cloak provides 20–50 dB reduction in scattering strength relative to the uncloaked configuration…
ZnO is a wide band-gap semiconductor with piezoelectric properties suitable for opto-electronics, sensors, and as an electrode material. Controlling the shape and crystallography of any semiconducting nanomaterial is a key step towards extending their use in applications. Whilst anisotropic ZnO wires have been routine…
