Phenotypic smooth cells of the fish pathogenic bacterium Flavobacterium psychrophilum have previously been reported to be more adhesive to polystyrene surfaces than corresponding rough cells. In this study, the adhesion ability of smooth and rough cells of F. psychrophilum to polystyrene surfaces was investigated in d…
Pure 2-iodo-9,9'-spirobifluorene was synthesized by an efficient method without troublesome iodination of 9,9-spirobifluorene (SP) or the Sandmeyer reaction of 2-amino-9,9'-spirobifluorene. A series of main group element-bridged bis-9,9'-spirobifluorene derivatives were synthesized via coupling reactions of 2-iodo-9,9…
In this paper, we present a method for the mathematically formulated phase engineering of interfering laser beams through a spatial light modulator for a holographic fabrication of graded photonic lattices. The desired phases can be programmed at specific locations by assigning gray levels in cellular structures. The…
Plant extract could be an alternative to traditional chemical methods for the production of metallic nanomaterials in a clean, nontoxic and ecologically sound manner. In the present study, we aimed to develop a rapid ecofriendly method for the synthesis of both silver and gold nanoparticles using pomegranate peel extr…
To answer the growing need for more versatile integrated spectral filters, we show that weak one-dimensional gratings can be designed towards any desired target spectrum. We follow a very straightforward design procedure to demonstrate the performance of these devices. Measurements and simulations show a very good cor…
Transcranial magnetic stimulation (TMS) has potential to treat various neurological disorders noninvasively and safely. There has been significant work on coil designs for use on the human brain; however, there are fewer reports on the coil design for small animal brains, such as mice. Such work is essential to valida…
Orbital-free density functional theory (OFDFT) directly solves for the ground-state electron density. It scales linearly with respect to system size, providing a promising tool for large-scale material simulations. Removal of the orbitals requires use of approximate noninteracting kinetic energy density functionals. I…
ZnO has attracted a great deal of research as a potential replacement of TiO2 for dye-sensitized solar cells (DSSCs), owing to the unique combination of interesting electronic properties (i.e., high electron mobility) and structural richness. Here, we present a DFT/TDDFT study about the interaction of the prototypical…
PURPOSE: To improve image contrast and B1+ field homogeneity in 3 Tesla (T) breast MR. MATERIALS AND METHODS: Two practical B1+ shimming methods for 3T breast MR are presented; low-cost passive shimming using local pads of high dielectric permittivity (εr from 0 to 100), and two-channel radiofrequency (RF) shimming (a…
Despite many years of intensive studies, γ-secretase complex assembly and maturation as well as the precise localization of its active form are still the subject of some controversy (St George-Hyslop and Fraser, 2012). Many lines of evidence show that γ-secretase subunits localize to almost all compartments of the cel…
Amorphous silicon/crystalline silicon (a-Si/c-Si) micromorph tandem cells, with best confirmed efficiency of 12.3%, have yet to fully approach their theoretical performance limits. In this work, we consider a strategy for improving the light trapping and charge collection of a-Si/c-Si micromorph tandem cells using ran…
Facile polymerized complex reactions together with a hydrothermal reaction were implemented to make single crystalline TiO2 nanorods for the first time. Chromium (Cr) and nitrogen (N2) co-doping was performed to tailor the physical properties. Transmission electron microscopy and x-ray diffraction study illustrated th…
The Hartman–Perdok analysis has been carried out on the monoclinic P 2 1 / c polymorph of Hydroxyapatite (HAp) in order to find the character of the main {hkl} forms and foresee the possible profiles of the related surfaces. Then, the corresponding specific surface energies have been calculated, at 0 K, by ab initio q…
The optimization of heat-sealing process parameters, including time, temperature, and pressure, was performed on a monolayer linear low-density polyethylene (LLDPE) film. The seal properties examined for each process condition were: seal initiation temperature (Tsi), plateau initiation temperature (Tpi), final plateau…
Chitin and sepia ink hybrid hemostatic sponge (CTSH sponge), a new biomedical material, was extensively studied for its beneficial biological properties of hemostasis and stimulation of healing. However, studies examining the safety of CTSH sponge in the blood system are lacking. This experiment aimed to examine whethe…
Human bone marrow-derived mesenchymal stem cells (hMSCs) are an ideal osteogenic cell source for bone tissue engineering (BTE). A scaffold, in the context of BTE, is the extracellular matrix (ECM) that provides the unique microenvironment and play significant role in regulating cell behavior, differentiation, and deve…
Abstract The synthesis of C3‐symmetrical tristriazolotriazines with conjugated arms and lateral alkoxy side chains was performed by a threefold condensation of cyanuric chloride with tetrazoles. Conjugated π segments include phenyl, tolane, and its phenylethynyl‐elongated homologue. Disclike and a dendritic molecule h…
Two new chitosan silver(I) complexes, [Ag(2CS)(H2O)(NO3)] and [Ag(2CS)(ahmp)(H2O)] (CS = chitosan, Hahmp = 4-amino-6-hydroxy-2-mercaptopyrimidine) were synthesized and characterized on the basis of elemental analysis, spectral (FT-IR and solid-state 13C-NMR), morphological (SEM, matrix analysis, XRD, and XRPE), and th…
We have developed a current doubling-induced two step photodeposition (CD-2PD) technique for forming selenium quantum dots (QDs) and metal selenide QDs on TiO 2, and proposed a reaction mechanism. Large aggregates of Se particles (∼100 nm) are generated on TiO 2 from aqueous and 2-methyl-2-propanol solutions of H 2 Se…
The influence of carbon on the oxygen reduction and evolution reactions (ORR and OER) on Ba0.5Sr0.5Co0.8Fe0.2O3-δ (BSCF) perovskite oxide has been studied in alkaline electrolyte. A lowering of the ORR overpotential by 100 mV for the BSCF/Carbon composite electrode compared to BSCF without carbon was observed, while f…
