The improved performance is demonstrated for mechanical sensors based on cholesteric paint covering elastic silicone substrate with imprinted grooves. Due to the presence of the grooves, the deformation of the substrate is translated to the deformation of the cholesteric paint differently along the grooves and perpend…
In this study, a Fresnel lens with radial and azimuthal liquid crystal (LC) alignments in the odd and even zones was fabricated using the photoalignment technique based on an azo dye doped in LC cells. The lens has approximately 35% focusing efficiency as determined using a linearly polarized probe beam. In addition,…
Structural phase transitions in two vertically or horizontally coupled channels of strongly interacting particles are investigated. The particles are free to move in the $x$ direction but are confined by a parabolic potential in the $y$ direction. They interact with each other through a screened power-law potential ($…
Fluorescent semiconductor nanocrystals, also called quantum dots (QDs), have unique electronic and optical properties. One of the most useful features of QDs is that whereas their absorption spectra are broad, their emission spectra are very narrow. Different QDs can emit different wavelengths of visible light under U…

Ion-gel-gated transistors enable controlled carrier doping into conjugated polymers in identical devices measurable at low temperatures. Using this technique, the carrier transport of regioregular poly(3-hexylthiophene) was investigated in a wide temperature range down to 15 K. At room temperature, carrier mobility ex…
Abstract In part 1 of this work, preparation, structure, spectroscopic, and electrochemical characteristics of the polypyrrole (PPy) deposited alumina/multi‐walled carbon nanotubes (MWCNTs) inhibitor particles (PDAMIPs) are presented. TEM observations evidenced uniform deposition of thin PPy film on the functionalized…
This research has been carried out to identify the strongest and weakest part of the human skull on high speed impact condition by using finite element simulation approach. There are nine parts of skull model to be examined, i.e., frontal bone, front mandible, side mandible, maxilla, nasal bone, occipital bone, pariet…
Based on chemical modeling of phase equilibria for the NH 4 Cl‐MgCl 2 ‐AlCl 3 ‐H 2 O system, a practical approach to produce Mg‐Al spinel (MgAl 2 O 4 ) (widely used as refractory brick, supports in catalysts, and inert material for oxygen carriers) is proposed and proven feasible. This novel process includes coprecipi…
The structure, magnetic properties, and magnetostriction of Pr(Fe1.95B0.05)1.93 alloys prepared by annealing its precursor amorphous ribbons under high pressure were investigated. It was found that Pr(Fe1.95B0.05)1.93 single cubic Laves phase could be obtained only when the pressure is up to 3 GPa. The average grain s…
Stability of the collagen triple helix is largely governed by its imino acid content, namely the occurrence of proline and 4R-hydroxyproline at the X and Y positions, respectively, of the periodic (Gly-X-Y)(n) sequence. Although other amino acids at these positions reduce stability of the triple helix, this can be par…

Biodegradable magnesium alloy with proper yield strength, high ultimate strength and elongation is a potential candidate for cardiovascular stent. Nevertheless, magnesium alloy with high ultimate tensile strength always exhibits high yield strength, which is not suitable for the plastic deformation of cardiovascular s…
Arteriovenous malformations (AVMs) are neurological defects in which the arterial and venous systems are connected directly, with no intervening capillaries. The absence of capillaries allows blood at high pressure to enter the venous system directly, and so a venous haemorrhage or a stroke is possible. AVMs can be tr…
The corrosion properties were investigated for extruded Mg–3Al–1Zn (AZ31) alloy in alkaline NaCl solution which was manufactured by adding 0.5 wt% CaO without SF6 protective gas. The results of electrochemical tests showed that the addition of 0.5 wt% CaO drastically increased the pitting potential and charge transfer…
Organic/inorganic multilayer barrier films play an important role in the semihermetic packaging of organic electronic devices. With the rise in use of flexible organic electronics, there exists the potential for mechanical failure due to the loss of adhesion/cohesion when exposed to harsh environmental operating condi…
Abstract Utilization of various types of multi‐walled carbon nanotubes (MWCNTs) in zinc‐rich paints (ZRPs) is presented addressing percolation and porosity related phenomena of traditional ZRPs. Hybrid paint coatings were formulated with 3.21 wt% polypyrrole (PPy) deposited alumina‐MWCNT inhibitor particles (PDAMIPs)…
The influence of chloride concentration on the salt spray corrosion behaviour of new AZ91D and AM50 alloys containing rare earth (RE) elements was evaluated. The corrosion rate of both materials increased with increasing chloride concentration, particularly for NaCl concentrations above 2 wt-%. The addition of Nd or G…
The present work arises from the significant difference between the experimental Landau tricritical point (LTCP) in the Sm A-to-N phase transition in binary mixtures of butyloxybenzylidene octylaniline (4O.8) and hexyloxybenzylidene octylaniline (6O.8) predicted by Stine and Garland, and that arising from the thermody…
Using advanced Cs-corrected scanning transmission electron microscopy, we have observed the atomic structures of coherent TiO2/LaAlO3 heterointerfaces in anatase TiO2 thin films deposited on single-crystal LaAlO3. Two epitaxial relationships are identified: (001)[100] TiO2//(001)[100] LaAlO3 and (001)[010] TiO2//(001)…
