Pure and Mg doped barium titanate ceramics were prepared by conventional solid state reaction method. The crystal structure, surface morphology and dielectric properties of Mg doped barium titanate ceramics were investigated. Mg2+ ions have entered the unit cell maintaining the perovskite structure of solid solution w…
Micro- or nanoelectromechanical system (MEMS/NEMS) is a multidisciplinary field, which has witnessed explosive growth during the past decades. The current materials for MEMS are dominated by Si thanks to the fully based technology for CMOS. However, Si has its own intrinsic limitations such as poor mechanical or tribo…
PURPOSE: The objective of the present investigation was to evaluate the antibacterial properties and the biocompatibility of composite electrospun nanofibrous membranes (NFMs) with low-molecular-weight fish scale collagen peptides (FSCP) and chito-oligosaccharide (COS), to determine their potential for use as wound dr…
Abstract Triangular gold nanoprisms with high yield percentage were synthesized via the seed‐mediated approach and functionalized by mono‐6‐thio‐β‐cyclodextrin without alkyl chain. The undecorated and decorated triangular gold nanoprisms were characterized and analyzed. Moreover, the novel decorated triangular gold na…
UNLABELLED: Wine grape pomace (WGP) (cv. Merlot) extract-based films were studied in terms of their physicochemical, mechanical, water barrier, nutritional, and antibacterial properties. Pomace extract (PE) was obtained by hot water extraction and had a total soluble solid of 3.6% and pH 3.65. Plant-based polysacchari…
First order Raman spectra of Si nanocrystals exhibit large shift and width, strongly exceeding the theoretical calculated values. The disagreement between theory and experiment is dramatically increasing for the smallest nanocrystal sizes. Here, we present a novel theoretical approach showing one-, two-, or three-dime…
This study reports the influence of poling a PMN-PT single crystal laminated structure on the magnetic properties of a 35 nm polycrystalline Ni thin film. During the poling process, a large anisotropic remanent strain is developed in the PMN-PT that is transferred to the ferromagnetic film creating a large predefined…
Abstract Raman spectroscopy has been used to study vanadates in the solid state. The molecular structure of the vanadate minerals vésigniéite [BaCu 3 (VO 4 ) 2 (OH) 2 ] and volborthite [Cu 3 V 2 O 7 (OH) 2 ·2H 2 O] have been studied by Raman spectroscopy and infrared spectroscopy. The spectra are related to the struct…
Cellulose acetate butyrate (CAB) and cellulose acetate propionate (CAP) were prepared homogeneously in a 1-allyl-3-methylimidazolium chloride (AmimCl) ionic liquid system from sugarcane bagasse (SB). The reaction temperature, reaction time, and molar ratio of butyric (propionic) anhydride/anhydroglucose units in the c…
Abstract This article presents a study of the polymer‐filler interfacial effects on filler dispersion and mechanical reinforcement in Polystyrene (PS)/silica nanocomposites by direct comparison of two model systems: ungrafted and PS‐grafted silica dispersed in PS matrix. The structure of nanoparticles has been investi…
Structural crystallography and nuclear magnetic resonance (NMR) spectroscopy are the predominant techniques for understanding the biological world on a molecular level. Crystallography is constrained by the ability to form a crystal that diffracts well and NMR is constrained to smaller proteins. Although powerful tech…
We have developed Metglas/Pb(Mg1/3Nb2/3)O3–PbTiO3 magnetoelectric (ME) laminates that have notably larger ME coefficients, with maximum values of up to 45 V/cm Oe. Based on this giant ME effect, the dc magnetic field sensitivity for Metglas/PMN–PT laminate sensors was improved by a factor of > 3, relative to th…
A bio-based thermoset resin was reinforced with flax fabrics and Lyocell fiber. The effect of different weave architectures was studied with four flax fabrics with different architectures: plain, twill (two different types), and dobby. The effect of the outer ply thickness was studied and characterized with flexural a…
The corrosion inhibition and adsorption processes of 1,2-diaminoanthraquinone (DAQ) on mild steel in HCl was studied at different temperatures (303 – 333 K) by means of weight loss measurement and UV-visible spectrophotometric methods. The results indicate that the studied compound exhibits good performance as inhibit…
The decomposition of the coarse primary M2C carbide in M2 high speed steel was investigated by using optical microscope, scanning electron microscope, energy dispersive spectrometer and X-ray diffraction analysis. It is indicated that the SEM observation using deeply etched samples can clearly reveal the details of th…
High quality NdFeO3 single crystal has been grown by the four-mirror image floating zone technique. The magnetic properties and specific heat of NdFeO3 single crystal were systematically studied in the temperature range from 2 to 300 K. A clear spin reorientation behavior is observed in a wide temperature range from 1…
We experimentally demonstrate the absorption properties of designed metamaterial absorbers in the near-infrared wavelength regime. For the rectangular-shaped case, we demonstrate its polarization dependent absorbance at various incident angles. For each polarization, the absorbance is insensitive to the incident angle…
In this contribution we present two ligands based on a do3a platform containing a picolinate group attached to the fourth nitrogen atom of the cyclen unit, which are designed for stable lanthanide complexation in aqueous solutions. Potentiometric measurements reveal that the thermodynamic stability of the complexes is…
The purpose of this study was to utilize low quality date syrup, a rich and available source of nutrient in Iran, for the production of bacterial cellulose using Gluconacetobacter xylinus. Static batch fermentation for the purpose of cellulose production by G. xylinus (PTCC, 1734) was studied using low quality date sy…
