In this research, materials characterization of transparent glass-ceramics containing ferroelectric potassium sodium niobate (K0.5Na0.5)NbO3 (KNN) crystals in a tellurite glass system were studied. The samples were prepared via an incorporation method. Glass-ceramics containing KNN crystals were successfully fabricate…
The well‐aligned Ag2O/ZnO microflowers heterostructure was synthesized by a straightforward two‐step procedure. The diameters of the as‐synthesized products were as much as 1.5 μm. The as‐grown Ag2O/ZnO heterostructure was investigated by X‐ray powder diffraction (XRD), scanning electron microscope (SEM), transmission…
The superparamagnetic nanoparticles (Fe3O4) were prepared by co–precipitation method, then the biocompatible silicon dioxide (SiO2) was coated on the surface of these Fe3O4 nanoparticles (designated as Fe3O4–SiO2) by using the sol–gel method. In order to graft chitosan on the surface of Fe3O4–SiO2 particles, the surfa…
In this study, an improvement in the heat resistance of cellulose fibers was achieved via the introduction of thermally stable siloxane bonds (Si-O), which were formed by promoting the reaction of cellulose hydroxyl groups with an organo-silicon compound. Currently, there are a number of green composite materials base…
The aim of this study was to characterize the concentrations of 40K, 226Ra and 232Th in the cement samples manufactured in Tlemcen (Algeria) using a high-efficiency gamma-ray spectrometer. Measurements of radioactivity in the environment are of great importance to monitor and control the levels of radiation to which m…
A novel red-emitting phosphor, CaYAl3O7 : Eu 3+ , Sm3+ , is synthesized by a combustion method at a low temperature (850℃), and the single phase of CaYAl3O7 is confirmed by powder X-ray diffraction measurements. The photoluminescence property results reveal that the red emission intensity of Eu3+ is strongly dependent…
Systemic AL Amyloidosis causes multiorgan dysfunction through interstitial expansion. We measured the extracellular volume fraction (ECV) in the : heart, liver, spleen and skeletal muscle in healthy volunteers and patients with Systemic Amyloidosis to test the hypotheses that (1) tissue ECV is greater in systemic AL A…
The stress–strain curves in semi-solid state of Al–4.5 mass%Cu alloy, whose deformation behaviors had classified into six stages in previous study, were investigated in this study. The mechanical properties, such as elastic modulus, derived from stress–strain curves are necessary to estimate the hot tearing by CAE. Sh…
Composite materials are used in many industries such: solar cells, optoelectronic device elements, light emitting diodes, aircraft, military and car industry. In this paper, effect of potassium chloride on physical and optical properties of polystyrene has been studied to use the new material in many applications. The…
Seeking new biomarkers for epithelial ovarian cancer, the fifth most common cause of death from all cancers in women and the leading cause of death from gynaecological malignancies, we performed a meta-analysis of three independent studies and compared the results in regard to clinicopathological parameters. This anal…
The present review highlights the development and relevance of various advanced nanocarrier systems in the field of nanomedicine for delivering drugs, contrast agents and antibodies to different sites in the body. Wherever appropriate, emphasis on targeting to tumor site is discussed to support the concepts. Several m…
Despite the recent progress and the extensive use of modelling and simulation techniques, physical testing remains a major instrument for the development and validation of railway vehicles in respect to their running dynamics. Not only are the present vehicle acceptance procedures mostly based on physical rather than…
The flammability characterization and synergistic effect of bentonite with magnesium hydroxide in polypropylene have been studied in this work. A synergistic effect on flame retardancy was found when bentonite was incorporated into magnesium hydroxide/polypropylene composites. The mass ratio of magnesium hydroxide and…

Calotrope (Calotropis procera) is an exotic woody shrub threatening the biodiversity and productivity of the rangelands in central and northern Queensland. It is widespread throughout the Gulf of Carpentaria region but is spreading into new areas where many land managers are not familiar with it. A collaborative resea…
In this study, we constructed tissue-engineered nerves with acellular nerve allografts in Sprague-Dawley rats, which were prepared using chemical detergents-enzymatic digestion and mechanical methods, in combination with bone marrow mesenchymal stem cells of Wistar rats cultured in vitro, to repair 15 mm sciatic bone…
We have conducted experiments to study the melting fragments from explosively shocked melting Pb targets. Based on the traditional Asay-Window technique, Asay-F-window was designed, which is suitable to investigate high-density melting fragments of metal sample. The areal mass and volume density of melting fragments f…
microRNAs (miRNAs) are small non-coding RNAs that regulate various biological phenomena, such as development and homeostasis. The dysregulation of miRNA leads to disease progression, particularly of c
O objetivo deste trabalho foi avaliar o potencial de pós de rochas na disponibilização de potássio em solos. O experimento foi conduzido em casa de vegetação utilizando as rochas olivina melilitito, granito e sienito. Amostras de um Cambissolo Húmico e de um Argissolo Vermelho-Amarelo foram coletadas, secas ao ar e pe…
