Metal-free organic phosphorescent materials are attractive alternatives to the predominantly used organometallic phosphors but are generally dimmer and are relatively rare, as, without heavy-metal atoms, spin-orbit coupling is less efficient and phosphorescence usually cannot compete with radiationless relaxation proc…
Quantum information processing (QIP) could revolutionize areas ranging from chemical modeling to cryptography. One key figure of merit for the smallest unit for QIP, the qubit, is the coherence time (T 2), which establishes the lifetime for the qubit. Transition metal complexes offer tremendous potential as tunable qu…
To date, numerous inorganic nanocarriers have been explored for drug delivery systems (DDSs). However, the clinical application of inorganic formulations has often been hindered by their toxicity and failure to biodegrade. We describe here a transformable liquid-metal nanomedicine, based on a core-shell nanosphere com…
The immobilization of radioiodine produced from reprocessing used nuclear fuel is a growing priority for research and development of nuclear waste forms. This review provides a comprehensive summary of the current issues surrounding processing and containment of 129 I, the isotope of greatest concern due to its long h…
Metal sulfide hollow nanostructures (MSHNs) have received intensive attention as electrode materials for electrical energy storage (EES) systems due to their unique structural features and rich chemistry. Here, we summarize recent research progress in the rational design and synthesis of various metal sulfide hollow m…
Austenitic chromium-nickel steel EK-164 is the promising material for manufacturing claddings of fuel pins of fast nuclear reactors. Physical and chemical compatibility with typical nuclear fuel compositions on the basis of uranium dioxide pellets is an important aspect of ensuring fuel cladding operability. Post-irra…
Due to their excellent antimicrobial properties, silver nanoparticles (AgNPs) have been extensively used for food industry, cosmetics, biomedicine and other application fields. Hence, the potential bio-safety of AgNPs has already garnered more attention. According to the results of domestic and foreign research, this…

Anthracene is a very stable organic chemical compound made up of polycyclic hydrocarbon which has entered an environment naturally or by human being. It is very dangerous compound in the environment. The purpose of this study is to eliminate or–reduce the pollutant by single wall carbon nanotubes (SWNTs). Single wall…
Organic polymers like Polyethylene and Teflon are used in the most of coaxial cables for insulation purposes. When dielectric insulators are subjected to ionizing radiation, radiation induced conductivity is observed. Thus, ionizing radiation deteriorates the insulating properties of these insulators resulting in a st…
Design and development of ultra low-cost, disposable devices for point-of-care diagnostics is the focus of scientific community in these days. In this work we propose a simple fabrication strategy, using non-conventional, low-cost, polycarbonate based micro-structured device which is supposed to be a low-cost, but hig…
The effect of substitution of Sr2+ ions for Ca2+ ions on the magnetic and magnetocaloric properties of a charge-ordered La0.5Ca0.5MnO3 manganite has been studied. The direct and inverse magnetocaloric effects corresponding to the paramagnetic–ferromagnetic and ferromagnetic–antiferromagnetic transitions have been dete…
The diazotization–azocoupling method has been utilized to prepare a series of previously unknown 4-[(E)-(4'-R-phenyl)diazenyl]phthalonitriles, which were further transformed into the corresponding cobalt phthalocyanines. The effect of the peripheral substitution of the phthalocyanine ligand on the spectral properties…
In this paper, we have investigated the structural and optical characteristics of ZnO thin film grown through Radio frequency magnetron (RF) sputtering technique on n-Silicon substrate. The surface morphological characteristics of the sample have been investigated by using Scanning electron microscope (SEM) and Atomic…
By employing trans -dicyano or pentacyanometalate as building block and using a bicompartimental Schiffbase based manganese(III) compound as assemble segment, two new cyanide-bridged heterometallic Fe(III)–Mn(III) complexes {[Mn(L)(H 2 O)][Febpb(CN) 2 ]}·2CH 3 OH ( 1 ) and {[Mn(L)(H 2 O)] 2 ··[Fe(CN) 5 NO]} ( 2 ) (bpb…
In nanometer regime, graphene nano-ribbon (GNR) has been identified as one of the prominent materials for on-chip interconnects. Current-mode signaling (CMS) has higher performance over conventional voltage-mode signaling (VMS) technique. VMS technique has received wide attention. However, impressive CMS technique has…
In order to measure electrical signals produced by partial discharges in hydrogenerators stator windings, capacitive couplers are regularly used. They are electrically connected to the windings and therefore, require undesired insulation intrusion. For avoiding such an intrusion, a microstrip directional coupler is us…
In this paper, a metamaterial based triangular shaped electromagnetic cloak is presented. The pi-shaped metamaterial shows wideband NZRI (near-zero refractive-index) characteristics in the C-band of microwave spectra. The metamaterial was then utilized in designing a triangular shaped cloak. The cloak hides a metal cy…
The structural properties and the phase transition for scandium carbide (ScC) have been studied in NaCl (B1), CsCl (B2), ZB (B3), WZ (B4), NiAs (B81), WC (B h ), and Pmmn structures by using the pseudopotential plane-wave method in the framework of the density functional theory. Our theoretical results show that the m…
We propose a description of switching in crystalline ferroelectrics taking into account the action of a varying external electric field, based on the equations of relaxation processes. We suppose that the probability of switching of domains depends not only on the instantaneous value of the controlling field, but also…
