The development of theranostic agents with high detection sensitivity and antitumor efficacy at low concentration is a challenging task for target selective imaging and therapy of cancers. In this study, folate-conjugated and radioactive-iodine-labeled gold nanorods (GNRs) were designed and synthesized for target sele…
The evolution of the Nb structure upon high-pressure torsion (HPT) in a Bridgeman chamber in liquid nitrogen and a subsequent annealing in the range from 100 to 600°C has been studied by the TEM method. With an increase in the degree of deformation, the structure exhibits three stages of refinement: dislocation cellul…
Effect of chemical treatments using sodium chlorite, sodium hydroxide and acrylamide monomer on thermal behavior of coconut husk (coir) fibre has been studied by means of scanning electron microscopy (SEM) and thermogravimetric analyses (TG, DTG, DTA). A significant variation in fibre surface occurred by chemical trea…
Metamaterials are defined as artificial electromagnetic structures based on the assembly of magnetic resonators and infinitely long metal rods at sub wavelength scale, which have the negative permittivity and the negative permeability simultaneously in a specific frequency range. However there are also some new metama…
The aim and novelty of this work was to compare the adsorption of totally-soluble chitosan (acidic solution) against the adsorption of precipitated chitosan, onto cellulose fibers. The influences of both these chitosan-adsorption procedures on a final amino group's content in functionalized cellulose fibers were studi…
Significant Alloy Elements in Welded Steel Structures of Car Body Structure, safety and exploitation conditions of welding steel in car body depend on many factors. The main role of that conditions is connected with car body material, welding technology, state of stress and temperature. Because of that, a good selecti…
Physical vapor deposition can be used to produce thin films with interesting material properties including extraordinarily stable organic glasses. We describe an ac chip calorimeter for in situ heat capacity measurements of as-deposited nanometer thin films of organic glass formers. The calorimetric system is based on…
Discoveries in the field of nanotechnology are triggering a revolution in medicine, by providing a profusion of potential and actual applications of nanosized objects in the diagnosis and treatment of several diseases. This trend is also evident in the increasing number of patents recorded annually. In particular, nan…
A simple, green mechanism for the UV assisted synthesis of graphene in the presence of phosphotungstic acid (PTA) is presented. The reduced graphene oxide (RGO) after UV exposure in the presence of PTA has been further identified as an efficient UV-absorber due to its complexation with PTA. This in turn could be used…
Eu doped aluminum nitride phosphors were successfully synthesized by a novel gas-reduction-nitridation route with a reaction temperature of 1400 °C and a soaking time of 3 h. The obtained AlN:Eu phosphors were analyzed to elucidate the location of the Eu luminescent center. High-resolution transmission electron micros…
Current III–V-based white light-emitting diodes (LEDs) are available. However, their yellow phosphor converter is not efficient at high currents and includes rare-earth metals, which are becoming scarce. In this paper, we present the growth of a fluorescent silicon carbide material that is obtained by nitrogen and bor…
Due to high incidence of vascular bypass procedures, an unmet need for suitable vessel replacements exists, especially for small-diameter vascular grafts. Here we produced 1-mm diameter vascular grafts with nanofibrous structure via electrospinning, and successfully modified the nanofibers by the conjugation of hepari…
Multi-walled carbon nanotubes (MWNTs)/Cu-doped ZnO composite powders were prepared by co-precipitation method, and were characterized by X-ray diffraction, electron microscopy, fluorescence spectrum, and ultraviolet spectrum. Experimental results show that the MWNTs can be modified by Cu-doped ZnO nanoparticles with h…
Studies of the optical properties of hydrosols of 4-nm detonation nanodiamond particles performed in the 0.2–1.1 μm range have revealed a novel effect, a strong increase of absorption at the edges of the spectral range, and provided its explanation in terms of absorption of radiation by the dimer chains (the so-called…
Open-circuit photovoltage and short-circuit photocurrent were investigated in BiFeO3 (BFO) ceramics as functions of laser wavelength (λ = 373 and 532 nm), illumination intensity, and sample thickness. BFO ceramics exhibit significant photovoltaic responses under near-ultraviolet illumination of λ = 373 nm. The photovo…
A material system that resists lead-bismuth attack and retains its strength at very high temperatures has been developed that enables increased outlet temperature and the promise of allowing increased coolant velocity and efficiency of lead- and lead-bismuth-cooled reactors if the behavior reported here is confirmed b…
Glycocalyx mimicking glycopolymer brushes presenting mannose, galactose and glucose residues in the pyranose form, similar to those present on cell surfaces, were synthesized on planar substrates (Si wafer, gold chip) and monodispersed polystyrene (PS) particles, and the interaction of blood to these surfaces were stu…
BACKGROUND AND PURPOSE: Gadobenate dimeglumine has proved advantageous compared with other gadolinium-based contrast agents for contrast-enhanced brain MR imaging. Gadobutrol is a more highly concentrated agent (1.0 mol/L). This study intraindividually compared 0.1-mmol/kg doses of these agents for qualitative and qua…
When crystallization screening is conducted many outcomes are observed but typically the only trial recorded in the literature is the condition that yielded the crystal(s) used for subsequent diffraction studies. The initial hit that was optimized and the results of all the other trials are lost. These missing results…
Abstract In this work, flowerlike ZnO micro/nanostructures assembled from nanorods are obtained through a facile hydrothermal route. The experimental results indicated that the as-synthesized ZnO microflowers have an average diameter of 2 µm, composed of nanorods of an average diameter of 200 nm and a tapered morpholo…
