The formation of porous alumina by galvanostatic anodization in selenic acid has been investigated. The influence of the electrolyte concentration on the morphological features and the self-ordering behavior of the porous oxide film has been studied. The best pore arrangement is obtained upon anodization in 0.5 M H 2…
The application of chemotherapeutic drug adriamycin (ADR) in cancer therapy is limited by its side effects like high toxicity and insolubility. Nanomedicine offers new hope for overcoming the shortcomings. But how to increase in vivo stability and to control intracellular drug release is a key issue for nano-based for…
Direct synthesis of gold nanoparticles (AuNPs) on cellulose fiber has been successfully performed via facile green approach using lignin‐containing unbleached kraft softwood pulp. The resulting AuNPs composited fibers showed apparent color change from pale yellow to purplish‐dark brown by varying the amount of gold io…
Plasma photonic crystals composed of periodic plasma and dielectric materials have attracted considerable attention because of their tunable photonic band gaps, but only their band structures or negative refractive index properties have been addressed in previous works. In this paper, through studying the transmission…
The metal‐insulator transition (MIT) in strongly correlated oxides has attracted considerable attention from both theoretical and experimental researchers. Among the strongly correlated oxides, vanadium dioxide (VO2) has been extensively studied in the last decade because of a sharp, reversible change in its optical,…
A characteristic iron-containing halloysite sample from Turkey was subjected to acid leaching using organic and inorganic acids for removing iron impurities. The aim of this study was to compare the raw hydrated and dehydrated halloysites with the leached products. Hydrochloric acid and oxalic acid were chosen as leac…
In the last decades the research on composite materials have been acquiring importance due to the possibility of increasing the material mechanical performances while contemporary decreasing both mass and volume of the structures. Composites are widely used in space vehicles and systems as structural materials, therma…
In this study, biodegradable poly(butylene adipate-co-terephthalate) (PBAT) and poly(butylene succinate) (PBS) binary blends were melt compounded. The mechanical, thermal and morphological properties of the PBAT/PBS blends were investigated. The melt compounded binary PBAT/PBS blends showed balanced mechanical propert…
Roots extract of Coptis chinensis (Berberine extract) was characterized using gas chromatography (GC) and Fourier transform infrared spectroscopy (FTIR) methods. The influence of berberine extract on corrosion of carbon steels (J55, N80, P110SS and C110 steels) in 3.5 wt.% NaCl solution saturated with CO2 was evaluate…
Hypervelocity impact experiments were done with a two-stage light gas gun to study the plastic deformation of metallic plates. Cylindrical Lexan projectiles were fired at A36 steel target plates with a velocity range of 4.5-6.0 km/s. Experiments were designed to produce a front side impact crater and a permanent bulgi…
Journal of Anthropology and Archaeology is a peer-reviewed international journal, which publishes original papers promoting theoretical, methodological and empirical developments in the discipline of socio-cultural anthropology.
Ni (II) tetraphenyl porphyrin, NiTPP, thin films were successfully prepared by using thermal evaporation technique. The dielectric properties and AC conductivity of thermally evaporated Au/NiTPP/Au thin films are investigated as function of temperature (303-443K) and frequency (42Hz-5MHz). The AC conductivity is found…
Zinc oxide (ZnO) nanoparticles of size varying from 16 to 31 nm were synthesised by co-precipitation method using zinc acetate dihydrate (Zn(CH 3COO) 2.2H 2O) and sodium hydroxide (NaOH) as precursor materials. The pH value of solution was varied to study the surface morphology and particle size variations in ZnO. The…
In this review paper the machining performance pertaining to the processing of Nickel- Titanium shape memory alloys is presented. High accuracy products for specialized applica- tions need to be machined in order to be shaped to their final form. However, shape memory alloys are characterized by poor machinability due…
The remarkable optical properties of the trivalent lanthanide ions including their characteristically narrow emission bands, size-independent emission and their capacity to (up)convert near-infrared (NIR) radiation to higher energies spanning the UV–NIR range of the spectrum renders them ideal for biological applicati…
The conventional methods for the synthesis of cordierite ceramics include the solid-state sintering of individual oxides of magnesium, aluminium and silicon of the corresponding chemical composition of cordierite, or sintering of the natural raw materials. Clays are used in the ceramics industries largely because of t…
Dopamine was self-polymerized onto the surface of a glassy carbon electrode (GCE), and the obtained polydopamine (PDOA) functioned as a scaffold for the grafting of half-polyamidoamine (H-PAMAM) dendrimers, which is a new class of polymeric biomaterial as drug carriers. Aspirin was chosen as the model drug and loaded…
This experimental study was carried out to verify the quality enhancement of Natural Rubber Products by drying methods and ascertain to what extent the different methods of drying affected the properties exhibited. During this study, samples of natural rubber coagulum were obtained and a sample each was subjected to o…
The defect chemistry of La 0.8 Sr 0.2 MnO 3±δ (LSM-20) is analyzed using the La-Sr-Mn-O quaternary thermodynamic database with the compound energy formalism model by applying the CALPHAD approach. The quantitative Brouwer diagrams for LSM-20 at 1000, 1100, and 1200°C are developed. The detailed analysis of the Mn 3+ c…
Despite development of new approaches for the treatment of cancer disease, it is the second cause of mortality in world. Annually, 30000 persons die in Iran due to cancer diseases. Eighty percent of cancer patients are children which about 50% children lead to death. Given the high rate of cancer-related death, the ne…
