Results of the experimental determination of the threshold voltage of pore formation for n -InP (100) crystals with a charge-carrier density of 2.3 × 10 18 cm −3 are presented. The threshold voltage of pore formation is shown to be a function of the electrolyte composition, in particular, of the acid concentration in…
A biomimetic and facile approach for integrating Fe 3 O 4 and Au with polydopamine (PDA) was proposed to construct gold-coated Fe 3 O 4 nanoparticles ( Fe 3 O 4 @ Au – PDA ) with a core–shell structure by coupling in situ reduction with a seed-mediated method in aqueous solution at room temperature. The morphology, st…
Electrospinning technique is commonly used to produce micro- and/or nanofibers, which utilizes electrical forces to produce polymeric fibers with diameters ranging from several micrometers down to few nanometers. Desirably, electrospun materials provide highly porous structure and appropriate pore size for initial cel…
Background: Acinetobacter baumannii plays a significant role in nosocomial infections. Multidrug-resistant A. baumannii is recognized to be among the most difficult antimicrobial-resistant Gram-negative bacilli to be controlled and treated. For this reason we examined the efficacy of nanosilver material with strong di…
Two different types of un-vulcanized natural rubber, air dried sheets (ADS) and SVR-3L block rubber, were investigated by a new testing method and the results are compared with other mechanical properties. It was found that green strength is strongly reduced if the sample is thermally treated before testing. Presuma…
The mechanism of oxygen transfer in layered nickelates having a Ruddlesden-Popper structure and their nanocomposites with Ce 0.9 Gd 0.1 O 2 − δ (GDC) and Y 2 (Ti 0.8 Zr 0.2 ) 1.6 Mn 0.4 O 7 − δ (YTZM) solid electrolytes having fluorite and pyrochlore structures were studied by the oxygen isotope heteroexchange method…
This research work evaluates several parameters that can affect Asphalt Rubber (AR) binder performance and applies the AR technology to the development of an innovative renewable bio-binder that can fully and cost-effectively replace asphaltic bitumen derived from petroleum in flexible pavement construction. The “Bind…
Density functional theory (DFT) calculations have been used to investigate the minimum energy structures of asparagine molecules on iron (Fe) (111) surface. Adsorption of the asparagine molecule on a Fe (111) surface has been studied computationally to generate adsorption configurations and to use the force field meth…
A new transport solution methodology was developed by combining the two-dimensional method of characteristics with the discontinuous Galerkin method for the treatment of the axial variable. The method, which can be applied to arbitrary extruded geometries, was implemented in PROTEUS-MOC and includes parallelization in…
The accurate X-ray diffraction study of a Ca 3 Ga 2 Ge 4 O 14 crystal (sp. gr. P 321, Z = 1) has been performed using repeated X-ray diffraction data sets collected on a diffractometer equipped with a CCD area detector at 295 and 100 K. The asymmetric disorder in the atomic positions in Ca 3 Ga 2 Ge 4 O 14 is describe…
Carbon and BN nanotubes have previously demonstrated extreme sensitivity to several molecules, but they cannot be used to detect highly toxic molecules of CO. In this work, we examine the possibility of a BC 3 nanotube (BC 3 NT) as a potential gas sensor for CO detection by using density functional theory calculations…
The objective of this study is to design and develop a green-synthetic, multifunctional hybrid micelles with shell embedded magnetic nanoparticles for theranostic applications. The hybrid micelles were engineered based on complex micelles self-assembled from amphiphilic block copolymers Pluronic F127 and peptide-amphi…
Anticancer drugs are typically distributed non-specifically in the body, where they affect both cancerous and normal cells. This limits the drug level achievable within the tumor, compromising the therapeutic efficacy, and results in potential toxic effects on normal tissues. Targeted delivery of chemotherapeutics exc…
Hydrolyzing the amorphous region of cellulose with high selectivity while protecting the crystalline region during acid hydrolysis of cellulose still remains a key technical barrier in cellulose hydrolysis and Microcrystalline Cellulose (MCC) production. This study investigated the effects of two transition metals (Fe…
Ba M-type ferrite films of composition BaFe11Zn0.5Zr0.5O19were grown on MgO (111) substrates by pulsed laser deposition. Both Zn and Zr divalent ions were introduced to reduce the magnetic anisotropy field to ~7.5 kOe, or 46% lower than the parent Ba M-type compound. Temperature dependence of magnetization over 25 to…
α-MoO3 nanorods were obtained by hydrothermal method. The influence of later heat treatment on its electrochemical properties was also investigated. In the electrochemical measurements, the annealed α-MoO3 nanorods exhibited better performance than the hydrothermal gained ones. It is proposed that the strong chemical…
Fenton-treated diamond nanoparticles have been submitted to hydrogen reduction at 500 °C with the purpose of modifying the nature of the functional groups present on the diamond surface. The nature of the functional groups on the diamond samples was characterized by a combination of spectroscopic and analytical techni…
A lead-free Bi0.5Na0.5TiO3 (BNT) piezoelectric composite thick film with a thickness of ~11 μm has been fabricated using a modified sol-gel method. Dielectric constant, remnant polarization, and coercive field of the BNT composite film were found to be 1018, 22.6 μC/cm2, and 76.1 kV/cm, respectively. The film was used…
Mg x Mn 1-x Fe 2 O 4 (x = 0.0, 0.2, 0.4, 0.5, 0.6 0.8 and 1.0) spinel ferrite system was synthesized by the chemical co-precipitation route. Subsequent characterization of synthesized Mg-Mn ferrites was carried out by X-ray powder diffraction and transmission electron microscopy to study the structural and textural pr…
The synergistic flame retardant effects between red phosphorus (RP) and alumina trihydrate (ATH) in silicone rubber (SR) composites were evaluated using limiting oxygen index, UL 94 rating, cone calorimeter, thermogravimetric analysis and digital photographs. It has been found that the SR composite containing only ATH…
