Both experiment and simulation works were utilized to research the deposition behavior of single coiled nanofiber on silicon substrate from Near-Field Electrospinning (NFES). In the experiment process, when the collector moving speed (CMS) is compatible with electrospinning speed, straight line nanofiber can be collec…
The first synthesis and characterization of metal coordinated complexes containing in situ prepared chiral trinitrogen 1,3-bis(4,5-dihydrooxazol-2-ylimino)isoindoline-based pincer ligands are reported. Two zinc complexes, isolated as Zn(L)(2), where L = 1,3-bis(4,5-dihydro-4-(R)-phenyloxazol-2-ylimino)isoindoline ((R,…
We have developed a novel approach to construct one-dimensional chiral assemblies from an achiral, dipolar dye molecule in the hydrophobic core of schizophyllan, a natural polysaccharide: they resulted in unusually red-shifted absorption maxima, in some cases appearing at the NIR region.
A series of novel supermolecular star-shaped tetrapede chiral liquid crystals (LCs), incorporating carbohydrates, methyl α-D-glucopyranoside or methyl α-D-mannopyranoside, as chiral cores surrounded by four cyanobiphenyl mesogenic groups linked by either C6 or C11 alkyl chain spacers, have been synthesised. These non-…
The use of living block copolymers as stabilisers in emulsion polymerisation allowed preparation of multilayer functional hairy particles via surface-initiated ATRP. Polymer films prepared from the obtained particles present antifouling properties along with stimuli-responsive behaviour.
Fe 81 − x Co x Ga 19 (with x ranging from 0 to 19 at. % Co) films were made by the dc magnetron sputtering method. We have studied the structural (phases, texturing, and grain size D), magnetic (saturation magnetostriction λS and coercivity HC), mechanical (Young’s modulus Ef and hardness Hf), and electrical (electric…
Historically, most SEM operators used accelerating voltages that were fairly high, quite often in the range of 15–20 kV. Now progress in electron optics has made low-voltage observations a routine mode of SEM operation. The greatly improved range of utilized accelerating voltages provides the SEM operator with additio…
The electrochemically assisted codeposition of sol-gel thin films on stainless steel is described. Specifically, electrodeposition of films based on aminopropyltriethoxysilane (APTS), and its codeposition with propyltrimethoxysilane (PrTMOS) and phenyltrimethoxysilane (PhTMOS) has been accomplished by applying negativ…
A new method was proposed for the application of azole corrosion inhibitors on the surface of copper. This method depends on the vacuum pyrolysis of the inhibitor in the presence of copper specimens. Three azole inhibitors namely; benzotriazole (Azole (1)), N-[Benzotriazol-1-yl-(phenyl)-methylene]-N-phenyl-hydrazine (…
Chitosan (CS) can mediate the formation of spherical, tabulate, and unique starfruit-like silica in the presence of phosphate ions (Pi). CryoTEM and cryoET were used to examine the CS aggregates in the hydrated state. 3D starfruit-like CS/Pi aggregates were reconstructed, which unambiguously confirmed the templating e…
Natural fibers are usually used as reinforcement in green composites. Especially, the use of slivers of natural fibers is anticipated for increasing composites' stiffness and strength. However the slivers have various fiber orientation angles and often involve fiber fluctuation. This paper describes effects of fiber o…
A novel single chamber solid oxide fuel cell operating at 550 °C was fabricated depositing a fully-dense, 650 nm thick, BaZr0.8Y0.2O3−δ (BZY) films on Ni-BZY anodes by pulsed laser deposition. Using an optimized cathode for proton conductor electrolytes, an open circuit voltage of 0.53 V and a power density output of…
We studied the influence of molecular size on the formation of transient networks by telechelic protein polymers with ∼2.3 kDa collagen-like triple helix-forming end-blocks and much longer random coil mid-blocks. We compared triblock copolymers with mid-blocks of ∼400 and ∼800 amino acids (37 and 73 kDa, respectively)…
Motion and morphology of triple junction during peritectic reaction process is analyzed for a model alloy system based on a quantitative-phase-field simulation for two-phase solidification involving diffusion in the solid. It is demonstrated that the dominative process controlling the motion of the reaction front grad…
The aim of the present work was to establish the relationship between dynamic behavior of Bisphenol A polycarbonate (BAPC) and degradation by gamma irradiation. The BAPC was exposed to 340 kGy dose and the molecular weight was evaluated by Size Exclusion Chromatography (SEC). A modified split Hopkinson pressure bar wa…
This study provides the effect of Cu addition on coercivity ( H cJ ) and interfacial microstructure in Nd-Fe-B/Nd-rich thin films. All films were deposited by using ultra high vacuum (UHV) magnetron sputtering, and the Nd-Fe-B layer was oxidized under several atmospheres with different oxygen content. Then, the films…
A high resolution optical microscopy study on low salt charged sphere suspensions settling under gravity reveals the formation of AB-stacked triangular layers via different transient structures. In particular, metastable triangular Moiré rotation patterns (formally corresponding to 1 × 1 Rα super structures) with rota…
A diacetylenic molecular hinge bearing two ethynyltriphenylene units (1) has been synthesized. Evidence from (1)H NMR and variable temperature NMR (VT-NMR) of 1 in comparison to model compounds bearing only one triphenylene unit suggests that there is an equilibrium between the open conformer and the intramolecularly…
ZnO is a wide band gap semiconductor which is used as transparent electrode in solar cells, chemical and gas sensors and light emitting diode etc. This paper reports the sol gel preparation and characterization of ZnO thin film. ZnO thin film was prepared by solgel process using zinc acetate dehydrate as a precursor,…
For a wide range of crystalline and amorphous materials, in the low frequency regime, the a.c. conductivity spectra is described by the well known Jonscher's power law equation. Recently, it has been shown that although the pre-exponential factor of the power law equation A and the power law exponent n are sensitive t…
