Abstract ZnO nanorods were prepared on the silicon (100) substrates using the chemical solution deposition method (CBD) without catalyst under a low temperature (90°C). The cool water was used to dissolve the mixture of zinc nitrate hexahydrate (Zn (NO 3 ) 2 ·6H 2 O) and methenamine (C 6 H 12 N 4 ) in order to decreas…
Abstract In this study, two types of nanoscale α‐Al 2 O 3 particles were used for preparation of α‐Al 2 O 3 /thermoplastic polyurethane (TPU) composites. These α‐Al 2 O 3 particles were either coated or uncoated with stearic acid. For the uncoated α‐Al 2 O 3 /TPU composite, the results of field‐emission scanning elect…
Polarization-resolved Raman microspectroscopy with near-infrared laser excitation was applied to intact human hair in order to non-invasively investigate the conformation and orientation of the polypeptide chains. By varying the orientation of the hair shaft relative to the polarization directions of the laser/analyze…
Abstract Fine Ni particles with sphere‐like architecture were synthesized via a wet chemical route in distilled water. The resulting fine Ni particles and/or commercial microsized Ni particles were then added to a mixed resin solution to fabricate resin‐based conductive composites. The shielding effectiveness (SE) of…
Abstract The nature of crystal lattice contacts is discussed because they reflect the selection of the most appropriate (for the given set of conditions) contact patches on the surface of protein molecules. The conclusion is that, along with chemical composition, the protein structure at the crystal lattice contacts i…
Abstract Biaxially oriented starch/polyvinyl alcohol (PVA) films were prepared by stretching starch/PVA blend precursor films that were fabricated by extrusion casting via a twin‐screw extruder. Investigations on crystallization, orientation morphology, and mechanical properties of extrusion cast and stretched starch/…
Abstract Commercial Poly(methyl methacrylate) (PMMA) containing Tinuvin 622, a Hindered Amine Stabilizer (HAS), in 0.3% (wt/wt) concentration was investigated. The samples were irradiated with gamma radiation ( 60 Co) at room temperature in air. The viscosity‐average molecular weight ( M v ) was analyzed by viscosity…
Stamping processes induce plastic strain and changes in the thickness, shape and mechanical behaviour of sheet metal parts. Simulated crash tests on vehicles should theoretically take these changes into account in order to be as realistic as possible, but this is not actually feasible because the calculations required…
In this paper, the mechanical response of two composites-based polypropylene (PP) is studied. High strain rate tests as well as quasi-static uniaxial tests were performed. Dynamic loadings were carried out using the Split Hopkinson Pressure Bar. Materials used consist of an unfilled high-impact PP (hiPP) and a talc-fi…
Abstract Polypropylene (PP)/clay nanocomposites were prepared by melt‐compounding PP with organomontmorillonite (OMT), using maleic anhydride grafted polypropylene (PP‐ g ‐MA) as the primary compatibilizer and N ‐imidazol‐ O ‐(bicyclo pentaerythritol phosphate)‐ O ‐(ethyl methacrylate) phosphate (PEBI) as the cointerc…
A family of novel titanasiloxanes containing the structural unit ([Ti(eta 5-C5Me5)O]3) were synthesized by hydron-transfer processes involving reactions with equimolecular amounts of mu3-alkylidyne derivatives [(Ti(eta 5-C5Me5)(mu-O))(3)(mu3-CR)] (R=H (1), Me (2)) and monosilanols, R3'Si(OH), silanediols, R2'Si(OH)2,…
Coverage of cardiovascular bioprostheses with autologous endothelium is used for the purpose of improving blood compatibility. The aim of our study was to analyze endothelialization potential of glutaraldehyde-fixed heart valves, cellular functions of seeded endothelial cells (EC), and the impact of a two-stage seedin…
A series of novel self-crosslinkable and biodegradable polymers, poly(hexamethylene carbonate-fumarate) and poly(hexamethylene carbonate) diacrylate, and their amphiphilic copolymers with polyethylene glycol, poly(ethylene glycol fumarate-co-hexamethylene carbonate-fumarate) (PEGF-co-PHMCF), were developed for tissue…
While separating two natural nano-sized triterpenic acids via bromolactonization, we serendipitously discovered that arjuna-bromolactone is an excellent gelator of various organic solvents. A simple and efficient method for the separation of two triterpenic acids and the gelation ability and solid state 1D-helical sel…
Abstract Bismuth telluride films were synthesized using pulsed electrodeposition. Synthesis of films from electrolytes with different [Bi]/[Te] ratios evidenced that an increase of bismuth concentration in the electrolyte leads to a decrease of the tellurium percentage in the film. A more important study with the rati…
Lanthanum zirconate (LZO) formation and growth kinetics between 1273–1673 K at the A‐site (La, Sr)‐deficient Sr‐doped lanthanum manganite (LSM)/yttrium‐stabilized zirconia (YSZ) interface were studied using high‐resolution transmission electron microscopy–energy‐dispersive X‐ray spectrometry (HRTEM–EDS). A cross‐secti…
Abstract In this study, four different Schiff bases namely 4,4′‐oxybis[ N ‐(2‐hydroxybenzilidene)aniline] (2‐HBA), 4,4′‐oxybis[ N ‐(4‐hydroxybenzilidene)aniline] (4‐HBA), 4,4′‐oxybis[ N ‐(3,4‐dihydroxybenzilidene)aniline] (3,4‐HBA), and 4,4′‐oxybis[ N ‐(4‐hydroxy‐3‐methoxybenzilidene)aniline] (HMBA) were synthesized.…
HfB 2 –SiC‐based ultra‐high‐temperature ceramics with aluminum nitride (AlN) as a sintering aid were hot pressed at 1850°C. The sinterability and mechanical properties were investigated and compared with the composite without a sintering aid. It was shown that the addition of AlN greatly improved the powder sinterabil…
Abstract In this paper, a novel route to synthesize manganese oxide (MnO 2 ) hollow urchins by a reactive template of carbon spheres is described. The formation process of the MnO 2 hollow urchins and the mechanism for the removal of the carbon spheres are suggested. The results of scanning electron microscopy and tra…
