Multiferroic materials, such as nanostructured h -YMnO 3, are expected to fulfill a crucial role as active components of technological devices, particularly for information storage. Herein, we report on the template mediated sol–gel synthesis of unique one-dimensional nanostructured motifs of hexagonal phase YMnO 3, p…
Abstract To improve the combustion behaviors of conventional consolidated propellants, consolidated propellants were prepared using porous propellant grains as fast‐burning filler. The porous propellant grains were prepared by supercritical fluid foaming process and exhibited the high burning rate. The multi‐perforate…
In this work, a spray-drying method was used to prepare densely structured Zn2SiO4:Mn phosphor particles. Several organic materials such as citric acid, sucrose, and dextrin were examined as additives to control the particle morphology. Consequently, dextrin was found to be the most effective organic additive for obta…
answered through this technology over the coming years. Based on the statistics obtained from thirty countries of the world, the number of consuming products by human being in which the nanomaterials are used, has increased from 54 in 2005 to 1628 in 2013 and it is predicted that this number would be rapidly increasin…
Polypropylene‐based composites filled with multi‐wall carbon nanotubes (MWCNTs), ranging from 1 to 6 wt%, were obtained by injection molding from a previous masterbatch compounded by twin‐screw extrusion (TSE). Resultant electrical percolation phenomenon was related to the ultrathin structure of the carbon‐based fille…
Stress development and fracture of isolated cristobalite spherulites in amorphous silica matrix were observed. High purity bulk silica was annealed to produce partial surface crystallization consisting of isolated and impinged spherulites in an amorphous matrix. The stress state of the amorphous silica surrounding cri…
Grain boundary and triple junction diffusion in nanocrystalline Cu samples with grain sizes, 〈d〉, of ∼35 and ∼44 nm produced by spark plasma sintering were investigated by the radiotracer method using the 63Ni isotope. The measured diffusivities, Deff, are comparable with those determined previously for Ni grain bound…
We present a first-principles investigation of the electronic structure and physical properties of doped lithium nitridometalates ${\mathrm{Li}}_{2}$(${\mathrm{Li}}_{1\ensuremath{-}x}{\mathrm{M}}_{x}$)N (LiMN) with M = Cr, Mn, Fe, Co, and Ni. The diverse properties include the equilibrium magnetic moments, magneto-cry…
The 3 d transition metal ( M ) perovskite oxides exhibit a remarkable array of properties, including novel forms of superconductivity, magnetism and multiferroicity. Strain can have a profound effect on many of these properties. This is due to the localized nature of the M 3 d orbitals, where even small changes in the…
The present article reports the development of soft nanohybrids comprising of single walled carbon nanotube (SWCNT) included silver nanoparticles (AgNPs) having superior antibacterial property. In this regard aqueous dispersing agent of carbon nanotube (CNT) containing a silver ion reducing unit was synthesised by the…
This study aims to produce reducing sugar hydrolyzed from substrate, coconut coir dust pretreated by recycled ionic liquid and its combination with alkaline. The 1H NMR and FTIR were performed to ver-ify the synthesized ionic liquid methylmethylimidazolium dimethyl phosphate ([mmim][dmp]). The structure of pretreated…
In this work, a new model was suggested to simulate the paste boriding process. This model was based on the numerical solving of the diffusion equations in both boride layer and substrate by taking into account the displacement of (Fe 2 B/substrate) interface. This diffusion problem with moving boundary was solved via…
The n-ZnO/p-Si heterojunction with an ultrathin Al₂O₃ buffer layer was prepared by atomic layer deposition. X-ray diffraction revealed that the crystalline quality of (100)-oriented ZnO films was improved with an Al₂O₃ buffer layer. The n-ZnO/p-Si heterojunction with 5 nm inserted Al₂O₃ layer shows the best electrical…
Purpose: To encapsulate paclitaxel into nanoliposomes, followed by pegylatation, in order to improve its therapeutic index and reduce side effects in breast cancer.Methods: In order to prepare nanoliposomal paclitaxel, varying ratios of phosphatidylcholine, cholesterol and paclitaxel were mixed and the formulations pe…
An aminohydroxylated polyester fabric with durable antibacterial activity, enhanced hydrophilicity and improved mechanical properties was prepared in one single step process. In the proposed method, synthesis of silver nanoparticles was carried out along with the aminohydrolysis of polyester fabric using triethanolami…
In recent years, poly (amido amine) (PAMAM) dendrimers have become a research focus in biomineralization fields. In this study, polyhydroxy-terminated PAMAM dendrimers (PAMAM-OH) were used to induce dentinal tubule occlusion. Demineralized dentin samples were coated with the second generation or the fourth generation…
Creating a facile and efficient method that can provide large-scale, highly aligned, and high strength nanofibers has proved extremely challenging. This work responds to these challenges by designing and evaluating poly(m-phenylene isophthalamide) (PMIA) nanofibrous materials with robust mechanical strength, which can…
Lactic acid is one of the top 30 potential building-block chemicals from biomass, of which the most extensive use is in the polymerization of lactic acid to poly-lactic-acid (PLA). To reduce the cost of PLA, the search for cheap raw materials and low-cost process for lactic acid production is highly desired. In this s…
