The development of appropriate processes for the synthesis of nanoparticles is an important aspect of nanotechnology. In this study, fungus mediated synthesis of silver nanoparticles using Microporus Xanthopus has been done. The dried macro fungi were powdered and boiled for 20 minutes to get the extracts. The extract…
Nanotechnology is a field of science which involves the synthesis and applications of nanoparticles. Silver nanoparticles (AgNp) have applications in various fields due to their unique optical, physical, electrical and medicinal properties. In this study, silver nanoparticles were synthesized by biophysical method. Si…
In this paper, copper oxide nanosheets were successfully fabricated in polyvinylpyrrolidone (PVP) via a quick precipitation method. The synthesized CuO nanostructures were characterized by X-ray diffraction (XRD), UV-vis spectroscopy, transmission electron microscopy (TEM), field emission scanning electron microscopy,…
The nonlinear optical properties of 27 selected donor-acceptor isomeric derivatives of naphthalene, quinoline, quinazoline and triazanaphthalene, including electron donor molecules such as phenyl, aminophenyl, and N, N-dimethylaminophenyl, were discussed and compared with literature values. The theoretical calculation…
Objective: Iron oxide nanoparticles have extensive application in MRI and heat therapy of canceras contrast elements. However, the effects of nanoparticles on human health have not been fully investigatedyet. In this study, effects of iron oxide nanoparticles on thyroid hormones (T3 and T4) and TSH in adult male wista…
The present work highlights the high efficiency of silver nanoparticles (Ag-NPs) coated onto activated carbon (AC) granules in antimicrobial activities for water purification. Silver nanoparticles (Ag-NPs) were prepared by polysaccharide reduction method. Silver nitrate was taken as the metal precursor and glucose as…
Molybdenum-99 is the parent of Technetium-99m, which is used in nearly 80% of all nuclear medicine procedures. The medical community has been plagued by Mo-99 shortages due to aging reactors, such as the NRU (National Research Universal) reactor in Canada. There are currently no US producers of Mo-99, and NRU is sched…
Surface-enhanced Raman scattering (SERS) is a promising analytical technique for the detection and characterization of biological molecules and structures. The role of hydrophobic and hydrophilic surfaces in the self-assembly of protein-metallic nanoparticle structures for label-free protein detection is demonstrated.…
Carbon nanorods and graphene-like nanosheets are catalytically synthesized in a hot filament chemical vapor deposition system with and without plasma enhancement, with gold used as a catalyst. The morphological and structural properties of the carbon nanorods and nanosheets are investigated by field-emission scanning…
BTBT ([1]benzothieno[3,2-b][1]benzothiophene) is an organic semiconductor that realizes high mobility in organic transistors. Here we report that the charge-transfer (CT) salt, (BTBT)2PF6, shows a high room-temperature conductivity of 1500 S cm(-1). This compound exhibits a resistivity jump around 150 K, but when it i…
The controllable self-growth of a supramolecular hydrogel of folic acid (FA) was developed based on the conduction of transition metal ions. The growth behavior of the gel could be flexibly controlled by adjusting the ambient environmental factors such as gelator concentration, temperature and external chemical stimul…
Solid samples of pure SiO2-glass are annealed at 1400 °C for 0.5–8 h in order to grow high-cristobalite which transforms to low-cristobalite during cooling. Crystal orientations are analyzed using X-ray diffraction up to 900 °C and electron backscatter diffraction (EBSD). Tensions during phase transformation lead to 1…
A cyclohexane-based ligand (1) as a triconnected linker forms a supramolecular gel in the presence of transition metal ions, particularly Cd2+ and Zn2+. 1 can also be gelated with cadmium counter ions such as NO3−, ClO4− and SO42−. The gels have been characterized by SEM, TEM, rheometry and single crystal X-ray crysta…
Rare-earth-doped yttrium aluminum garnet (YAG:RE) phosphors have good photoluminescence (PL) properties and are widely used in light-emitting diodes. However, the RE elements used in these phosphors are expensive and in short supply. It is therefore important to develop phosphors that contain smaller amounts of RE mat…
We directly observe non-fluorescent nanodiamonds in living cells using transient absorption microscopy. This label-free technology provides a novel modality to study the dynamic behavior of nanodiamonds inside the cells with intrinsic three-dimensional imaging capability. We apply this method to capture the cellular u…
GdPO4:Eu hollow spheres (denoted as GdPO4:Eu HMNs) with large pore channels in the shell have been designed as gene carriers while simultaneously acting as dual-mode bio-imaging probes.
500 nm thick Mg–Pd films with different structures were prepared and their hydrogen storage properties were investigated. Results indicated that thin Ti interlayers in the Mg bulk film could significantly improve the hydrogen sorption kinetics and reversibility, offering an effective way to improve the hydrogen storag…
Six new hybrid species based on amino acid functionalized γ-octamolybdates, [(H2O)3M]2[Mo8O26(pro)2]·2H2O (M = Cu 1, Zn 2, Co 3), [(H2O)8(lys)2Cu3][Mo8O27]·12H2O (4), and [(H2O)6M][Mo8O26(lysH)2]·4H2O (M = Zn 5, Co 6) (pro = proline; lys, lysH = lysine), have been synthesized and characterized by elemental analysis, I…
We present a brief overview of some of the most prominent examples of encapsulation of molecules inside carbon nanotubes. We then relate them to mechanically interlocked molecules, and in particular rotaxanes, by examining the most prominent features of the mechanical bond (topology, dynamic properties, and stability)…
