Recent advances in the application of nanotechnology in medicine, often referred to as nanomedicine, may revolutionize our approach to healthcare. Cancer nanotechnology is a relatively novel interdisciplinary area of comprehensive research that combines the basic sciences, like biology and chemistry, with engineering…
Nanoencapsulation of antioxidant molecules on protein nanoparticles (NPs) could be an advanced approach for providing stable, better food nutraceuticals and anticancer drugs. The bioavailability and stability of catechin (CAT) and epicatechin (ECAT) were very poor. In the present study, the CAT and ECAT were loaded on…
Biologically synthesized nanoparticles have been widely using in the field of medicine. Research in nanotechnology highlights the possibility of green chemistry pathways to produce technologically important nanomaterials. Present study focuses on the Biological synthesis of Zinc oxide nanoparticles (ZnO-NPs) by Zinc a…
Graphene was synthesized for the first time one decade ago and, during this time, the structure and properties of graphene have been well defined by many scientists. In parallel, some new graphene-based devices appeared, such as graphene field effect transistors, supercapacitors and micro electromechanical systems. No…
Luminescence properties of Eu <sup>III</sup> , Tb <sup>III</sup> , Gd <sup>III</sup> and Nd <sup>III</sup> complexes with a hexadentate ligand (abbreviated to Eu <bold>L</bold> , Tb <bold>L</bold> , Gd <bold>L</bold> , and Nd <bold>L</bold> , respectively), which have two bipyridine moieties bridged by an ethylenediam…
In this paper, carbon nanodots (C-dots) were prepared using a hydrothermal method and were characterized by UV-vis absorption spectroscopy, fluorescence spectroscopy, transmission electron microscopy and atomic force microscopy. The as-prepared C-dots show a blue emission at 410 nm and the diameter of the C-dots was i…
Heteroleptic neutral copper(I) dipyrrin complexes have been synthesised with the general formula [Cu(4,4'-(R)-6,6'-(CH3)-bipyridine)(dipyrrin)], R = CH3 or CO2Et, and H-dipyrrin is either 1,3,7,9-tetramethyldipyrromethene (HL1), 1,13-diphenyl-6,8-diisoindolemethene (HL2), or 1,13-diphenyl-3,11-di(trifluoromethyl)-6,8-…
The first use of the flexible Schiff base ligand N-salicylidene-2-aminocyclohexanol in metal cluster chemistry has afforded a new family of Ln7 clusters with ideal D(3h) point group symmetry and metal-centered trigonal prismatic topology; solid-state and solution studies revealed SMM and photoluminescence behaviors.
The integration of cellulose with electronic elements could form green electronics with the merits of the biopolymer and conductive polymer.
An alternative approach for hydrogenation of silicene is proposed through applying an external electric field in order to reduce the reaction energy barrier based on density functional theory calculations. It is found that a positive perpendicular electric field F can act as a catalyst to reduce the energy barrier of…
Rare earth metal borohydrides have been proposed as materials for solid-state hydrogen storage because of their reasonably low temperature of decomposition. New synthesis methods, which provide halide-free yttrium and gadolinium borohydride, are presented using dimethyl sulfide and new solvates as intermediates. The s…
In this study, micro-plasma discharge is produced by applying a high electric potential between graphite and Pt electrodes in acetonitrile solvent.
A simple, solvent-free method was developed for preparation of fluorescent NSCPs by direct pyrolysis of gentamycin sulfate. The NSCPs showed high water-solubility, long lifetime, high quantum yield, excellent stability and low cytotoxicity, and thus can be used for cellular imaging.
The surface modification of nanocrystalline TiO2 particles (45 Å) with catecholate-type ligands having different electron donating/electron withdrawing substituent groups, specifically 3-methylcatechol, 4-methylcatechol, 3-methoxycatechol, 3,4-dihydroxybenzaldehyde and 4-nitrocatechol, was found to alter the optical p…
A structural investigation of sub-15 nm xEu:BaTiO3 nanocrystals (x = 0-5 mol%) was conducted to determine the distribution of the Eu(3+) ion in the BaTiO3 lattice. Pair distribution function analysis of X-ray total scattering data (PDF), steady-state photoluminescence, and X-ray absorption spectroscopy (XANES/EXAFS) w…
We report here the first solid-state, NIR-selective electrochromic devices. Critical to device performance is the arrangement of nanocrystal-derived electrodes into heteromaterial frameworks, where hierarchically porous ITO nanocrystal active layers are infiltrated by an ion-conducting polymer electrolyte with mesosca…
Exfoliation of bulk molybdenum disulfide (MoS 2 ) using sonication in appropriate solvent is a promising route to large‐scale preparation of few‐layered or monolayered crystals. Grinding‐assisted sonication exfoliation was used for preparing monolayered MoS 2 nanosheets from natural mineral molybdenite. By controlling…
Semiconductor/metal composite nanomaterials have been used as surface-enhanced Raman scattering (SERS) active substrates and have attracted increasing attention due to their widespread applications in both optical and material fields. Here, we report a facile strategy to prepare highly sensitive SERS substrates with e…
Nb- and W-KIT-6 materials display significant ethylene epoxidation activity with H <sub>2</sub> O <sub>2</sub> as the oxidant at mild temperatures that eliminate substrate burning.
The establishment of a relationship between device performance parameters is reported here for a versatile one-step preparation method of a large area solid-state electrochromic device.
