The crystal structure of ramdohrite, Pb 5.9 Fe 0.1 Mn 0.1 In 0.1 Cd 0.2 Ag 2.8 Sb 10.8 S 24 , from the Chocaya mine, Potosí, Bolivia, determined by Makovicky and Mumme from film data in 1983, was refined from single-crystal diffractometer data to the R value 0.060, based on 5230 reflections [I > 2σ(I)] from a twinn…
Multichannel transition visible and near-infrared (NIR) fluorescences have been captured in Dy3+-doped fiber-adaptive Na2O–ZnO–PbO–GeO2–TeO2 glasses. The maximum stimulated emission cross-sections σem-max were derived to be 0.33 × 10−21, 3.66 × 10−21, and 0.67 × 10−21 cm2 for conventional visible emissions assigned to…
Oxygen-stoichiometric La0.5Sr0.5M0.5Ti0.5O3 (M = Mn, Fe) perovskites and the corresponding reduced specimens, of La0.5Sr0.5M0.5Ti0.5O3-δ composition, have been prepared and characterized by x-ray diffraction and neutron powder diffraction (NPD), in complement with thermal analysis, electrical conductivity, and thermal…
FeoB is a transmembrane protein involved in ferrous iron uptake in prokaryotic organisms. FeoB comprises a cytoplasmic soluble domain termed NFeoB and a C-terminal polytopic transmembrane domain. Recent structures of NFeoB have revealed two structural subdomains: a canonical GTPase domain and a five-helix helical doma…
r-PET fibers are basically derived from recycling PET bottle wastes. These fibers can be accepted as eco-friendly because of theiradvantages and contributions to the reduction of energy and raw material costs. In this study, properties of the yarns produced by r-PETfibers and their blends and their availability for te…
In order to confirm the irradiation behavior of ODS steels and thus judge their applicability to fuel claddings, fuel pin irradiation tests using 9Cr and 12Cr-ODS claddings developed by JAEA were conducted to burn-up of 11.9 at% and neutron dose of 51 dpa in the BOR-60. Superior properties of the ODS claddings concern…
A method of enlarging the surface area of monolayer graphene produced by mechanical exfoliation of graphite and increasing the possibility of obtaining monolayer graphene is suggested. The enlargement of the surface area of monolayer graphene is due to additionally cleaving few layer grapheme adjacent to the monolayer…
With PR81 as a murine monoclonal antibody (mAb) that was prepared against the human breast cancer, the MUC1 receptor specific targeting is possible. In this study, PR81-conjugated bovine serum albumin (BSA) nanoparticles loaded with anticancer drug 5-fluorouracil (5-FU) were developed. Enzyme linked immunosorbant assa…
Karenwebberite, Na(Fe 2+ ,Mn 2+ )PO 4 , belongs to the triphylite group of minerals and corresponds to the Fe-equivalent of natrophilite or to the Na-equivalent of triphylite. It occurs in the Malpensata pegmatite dike, Colico, Lecco Province, Italy. Karenwebberite is found as late-magmatic-stage exsolution lamellae u…
SUMMARY: Advances in nanotechnology have the potential to dramatically enhance the detection of neurologic diseases with targeted contrast agents and to facilitate the delivery of focused therapies to the central nervous system. We present the physicochemical rationale for their use, applications in animal models, and…
Lead Telluride (PbTe) with bismuth secondary phase embedded in the bulk has been prepared by matrix encapsulation technique. X-Ray Diffraction results indicated crystalline PbTe, while Rietveld analysis showed that Bi did not substitute at either Pb or Te site, which was further confirmed by Raman and X-Ray Photoelect…
Several approaches have been investigated in recent years in the area of small molecule activation. The current work introduces a new concept in this field: that of molecular cages, containing only main group elements, serving to activate small molecules. Full quantum mechanical calculations employing DFT/SCS-MP2 meth…
Polyethylene (PE) is one of the most produced synthetic resins in the world. Functionalized multiwalled carbon nanotube (MWCNT) is a potential nanoscale filler to realize the next generation strong and multifunctional PE composites. We demonstrate that MWCNTs grafted with short n ‐alkyl groups are effective nanofiller…
Density functional theory (DFT) calculations were performed to study the crystallographic properties of the cis-vacant form of dioctahedral 2:1 phyllosilicates. Samples with different layer charges are studied; only tetrahedrally charged, only octahedrally charged, or mixed octahedrally/tetrahedrally charged. The isom…
Abstract We present herein a new single probe, polyethyleneimine (PEI)/MnZnS nanocomposite, for two‐color imaging and three‐dimensional sensing. The PEI/MnZnS nanocomposite possesses unique, individually excited, two‐color, photoluminescence (PL) emissions at λ =495 and 585 nm; this allows two‐color imaging of the s…
The acoustic emissions from single cavitation clouds at an early stage of development in 0.521 MHz focused ultrasound of varying intensity, are detected and directly correlated to high-speed microscopic observations, recorded at 1 × 10 6 frames per second. At lower intensities, a stable regime of cloud response is ide…
Polyvinyl alcohol (PVA)/Na-rich Montmorillonite (MMT) nanocomposites were prepared using solution method to create polymer-clay nanocomposite (PCN) material. The PCN material was studied using X-ray diffraction (XRD), demonstrating polymer-clay intercalation that has a high d -spacing (lower diffraction angles) in the…
The structural phase transition has been observed for the first time in the Rb${}_{2}$NaYF${}_{6}$ crystal and studied by EPR and optical spectroscopy. EPR spectra of Dy${}^{3+}$ and Yb${}^{3+}$ ions present as unintentional dopants in the nominally undoped crystal and forming tetragonal paramagnetic centers have been…
Abstract Streamwise variation in vessel geometry is a feature of many multiphase flows of practical interest, ranging from natural porous media flows to man-made lab-on-the-chip applications. The variable streamwise geometry typically exerts a dominant influence on bubble motion, and can lead to undesirable phenomena…
Abstract A stable suspension of simple manganese(III) meso ‐tetraphenylporphyrin nanoaggregates was prepared by a host–guest procedure, in which ethanol and water are used as “green” solvents. The organic nanoparticles were studied by dynamic light scattering (DLS), AFM, and UV/Vis and fluorescence spectroscopy. The r…
