A short-range order of liquid ternary Al62Cu25.5TM12.5 (TM = Mn, Ni, Fe) alloys was investigated by X-ray diffraction and reverse Monte Carlo simulation. The causes of the shoulder on second maximum and the prepeak on the structure factors were discussed. The prepeak is caused by chemical short-range order (CSRO) in t…
The new Ni(II) metallomesogenes were synthesized. Their mesogenic cores are constructed from tetradental enaminoketone unit connected to 1,2:3,4-di(4,5-dioctyloxybenzo)phenazine or 2,3-di(3,4-dioctyloxyphenylo)quinoxaline. The described compounds form columnar hexagonal phase (Colhd) in very broad temperature range. T…
Abstract Ternary solubility data of the chiral 3‐chloromandelic acid (3ClMA) system are estimated for different solvents from binary solubility data using the non‐random two‐liquid (NRTL) model and compared to experimental data. The parameters of the NRTL model are determined by minimizing an objective function based…
The research field of nanoparticle synthesis and related nanoparticle applied sciences have been steadily growing in the past two decades. The chemical synthesis of nanoparticles was improved up to the point that the organic and inorganic nanoparticle colloids are produced with a low size dispersion and with a well de…
Wafer-scale graphene on SiC with uniform structural and electrical features is needed to realize graphene-based radio frequency devices and integrated circuits. Here, a continuous bi/trilayer of graphene with uniform structural and electrical features was grown on 2 inch 6H-SiC (0001) by etching before and after graph…
Relaxor ferroelectric single crystals exhibit anisotropic piezoelectric behavior. This enables the use of a combination of crystal cut and poling to obtain piezoelectric properties optimized for certain applications. This work describes a crystal cut that is optimized for applications where a strong face shear mode d3…
We examined whether expediting angiogenesis in porous polycaprolactone (PCL) scaffolds could reduce hypoxia and consequently improve the survival of transplanted enteric cells. To accelerate angiogenesis, we delivered vascular endothelial growth factor (VEGF) using PCL scaffolds with surface crosslinked heparin. The f…
In the present study, through a transmission experiment, the effects of europium complex and Eu3+ on the pearl colour in the pearl oyster Pinctada martensii were evaluated. Europium complex and europium salt were respectively enriched by dietary green algae platymonas subcordiformi, and their toxicity to algae were an…
Abstract In this paper, a series of composites containing of the oligo‐phenol (produced by reacting of 4‐methyl‐phenol with dicyclopentadiene and isobutylene (MPDI)) as organic fillers, and chlorinated butyl rubber (CIIR)/acrylate rubber (AR) as matrix were prepared by melting blending method. The selective distributi…
This present study deals with the compression creep behaviour of polyester needle-punched nonwoven fabrics. Polyester fibres of three different cross-sectional shapes (round, circular hollow and trilobal) have been selected for this study. An instrument has been designed and fabricated to measure the compression creep…
By using the Pontryagin's maximum principle, we determine optimal shape of a nonlocal elastic rod clamped at both ends. In the optimization procedure, we imposed restriction on the minimal value of the cross-sectional area. We showed that the optimization may be both unimodal and bimodal depending on the value of the…
High resolution spectroscopy (the finest being 0.01 cm(-1)) was applied in the 75-25,000 cm(-1) and 9-300 K ranges to a 1 mol% holmium doped Y PO(4) single crystal with two purposes: (1) to study the hyperfine splitting of Ho(3+) energy levels of interest for possible quantum manipulation media and (2) to analyze the…
Abstract The effect of Pb in La 3 Te 4− x Pb x on the thermoelectric properties in the temperature range 300–1100 K was studied on samples synthesized by the melting, ball milling and hot-pressing method. The samples crystallize in the Th 3 P 4 structure. A small amount of Pb substitution for Te in La 3 Te 4 reduced t…
Measured wear data is presented for three different carbide grades. The data were collected during rip sawing wood with a double arbour saw. The purpose of the test was to determine the suitability of different grades for sawing frozen timber. A set of circular saw blades of diameter 350 mm was equipped with teeth com…
The synthesis, characterization, and application as polymers and anti-wear additives of nanosized zinc oxide particles obtained by conventional and supercritical ethanol drying are reported in this study. The nanaoparticles of ZnO produced by the two different drying techniques were characterized using Fourier Transfo…
β‐eucryptite ( LiAlSiO 4 ) has received widespread attention, both industrially and academically because of its low negative average coefficient of thermal expansion ( CTE ) and one dimensional Li‐ion conductivity. It undergoes a reversible pressure‐induced phase transformation at ~1 GPa to a metastable polymorph, ε‐e…
Abstract In this work, the thermoplastic starch–kaolinite (KAO) nanocomposite films were first prepared via solution‐casting method using chitosan‐modified KAO (CKAO) and Na + –KAO (NKAO). The structure was investigated by X‐ray diffraction, scanning electron microscopy, and Fourier transform infrared spectroscopy tec…
Novel vertical alignment (VA) mode is presented for fast response and wide viewing angle in the LCD panel. The key concept of the new mode is that the pre-tilt for fast response and multi-domain is generated in the surface of alignment layer composed of vertical alignment part and photo-reactive moiety. The UV treatme…
The Langmuir–Blodgett (LB) method has long been used for the preparation of ultrathin films, offering the unique control over the film thickness and the molecular orientation. Here, we report on the deposition and the characterization of LB layers of polyaniline (PANI) nanotubes on solid supports. Stable suspension of…
The effects of ex situ vacuum and oxygen annealing treatments on thin films of the low-bandwidth compound Pr(1-x)Ca(x)MnO(3) (PCMO) are investigated. Structural and magnetic measurements reveal that increased ferromagnetism can be achieved by oxygen annealing treatment, which is linked to the increased Mn(4+) ion cont…
