Thin films of nickel-zinc ferrite with general formula Ni x Zn 1-x Fe 2 O 4 (where x = 0.5, 0.6, 0.7, 0.8, 0.9, 1.0) has been prepared using spray pyrolysis technique onto the glass substrates at optimized substrate temperature of 400 °C. The nickel nitrate, zinc acetate and ferric nitrate were used as precursor mater…
Although various strategies have been reported for double-stranded DNA (DNA) detection, development of a time-saving, specific, and regeneratable fluorescence sensing platform still remains a desired goal. In this study, we proposed a new DNA detection method that relies on an "off-on" switch of a regenerated fluoresc…
A mechanochemical process for the synthesis of alane (AlH3) starting from lithium hydride (LiH) and aluminium chloride (AlCl3) at room temperature and the underlying reaction pathway have been studied. In contrast to a conventional process using the same two reactants dissolved in diethyl ether, our approach enables a…
Here we describe the design and synthesis of a bifunctional two-photon fluorescence probe, N,N'-dimethyl-4,4'-(biphenyl-2,1-ethenediyl)dipyridinium hexafluorophosphate (BP6). HeLa, Hek293, and Paramecium caudatum cells were stained with BP6. BP6 accumulated on the mitochondria of all three cell types when the mitocho…
It is demonstrated that a theory of zero-order mode resonator (ZOR) metamaterial (MTM) structure can be used for the development of a novel class of applicators for microwave thermotherapy, for example, for hyperthermia in cancer treatment or for physiotherapy. The main idea of creating such an applicator is to genera…
An account is given of some principal observations made from a series of experiments in which metal cylindrical shells were subjected to lateral explosion impact by different TNT charge mass and stand-off distance. These cylindrical shells were filled with water in order to identify the main effects produced by the fl…
Transformation electromagnetics (TE) has been used to predict many unconventional and potentially game-changing electromagnetic devices, but they are often left unimplemented due to the complexity of the required material properties. Restricting transformations to quasi-conformal mappings allows all-dielectric gradien…
The morphology of NiO nanostructures was controlled by tuning the pH value <italic>via</italic> a hydrothermal process.
Alloy nanoparticles on oxide supports are widely used as heterogeneous catalysts in reactions involving oxygen. Here we discuss the oxidation behavior of Pd-Rh alloy nanoparticles on MgAl2O4(001) supports with a particle diameter from 6-11 nm. As an In situ tool, we employed high energy grazing incidence X-ray diffrac…
Visible light-sensitive ZnO nanoplates (ZnO NPls) were successfully synthesized using a hydrothermal sol-gel method and their structures were characterized by using techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM), transmitting electron microscopy (TEM), atomic force microscopy (AFM) and…
The optical, electrical and electro-optical properties of metal-insulator-semiconductor (MIS) devices containing Si-rich silicon nitride (SRN) films are reported. The photoluminescence and optical absorption characterization evidences that optically active centers present a defective nature. As a consequence, a Poole-…
Electrochemical impedance spectroscopy (EIS) has been applied to the study of electrodeposited thin films of manganese dioxide as used in electrochemical capacitors. Conventionally EIS employs a relatively small AC excitation signal to provide valuable characterization on electrode features such as the series resistan…
The SAR values of the magnetic nanocomposites increased by approximately two-fold when the concentration was reduced by a factor of 3.
The room temperature Raman, photoluminescence and low temperature photoluminescence properties are examined to give a deeper understanding of CuAlO <sub>2</sub> .
Polycrystalline diamond (PCD) has become an indispensable tool material for efficient machining of various materials. In manufacturing of PCD tools the finishing process in order to obtain the required surface and edge quality is mostly done by grinding. Due to the high hardness and wear resistance of PCD grinding is…
Plasticized poly(vinyl chloride) (PVC) is one of the most widely consumed commodity plastics. Nevertheless, the commonly used plasticizers, particularly phthalates, are found to be detrimental to the environment and human health. This study aimed to investigate the ability of an alternative greener material, medium-ch…
Metal oxide layer helps to support carbon nanotubes (CNTs) aligned perpendicular as well as preventing the tip-growth which takes place due to the strong adhesion force between the catalyst and metal oxide. However, in this work we discovered tip-growth of aligned CNTs with Co as catalyst on thermally oxidized Al/SiO2…
The FeCrNi alloy, whose composition is close to that of stainless steel 304, was prepared by electrodeposition and characterized. Nanocrystalline FeCrNi (nc-FeCrNi) was obtained by employing a double-compartment cell where the anode is separated from the cathode compartment, while amorphous FeCrNi (a-FeCrNi) was depos…
PPy film/TiO <sub>2</sub> nanotubes composite show enhanced cycling performance and higher specific capacity as an anode material for supercapacitors.
Various functional groups can be easily introduced onto the poly(α,β-L-aspartic acid) by using different reagents to open the succinimide ring in polysuccinimide (PSI). In this work, two natural basic amino acids, L-histidine and L-lysine were used as the ring opening reagents to react with PSI. As a result, both posi…
