Here the large-area hierarchical Bismuth Molybdate nanowires have been successfully prepared via a facile electrodeposition-heat-method. X-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) and laser micro-Raman spectrometer measure…
This work reports the analytical application of surface-enhanced Raman spectroscopy (SERS) in the trace analysis of organophosphorous pesticides (trichlorfon and glyphosate) and model organophosphorous compounds (dimethyl methylphosphonate and o-ethyl methylphosphonothioate) bearing different functional groups. SERS m…
In this study, electrochemical investigation of corrosion protection and electrochromic properties of aniline-pentamer-based electroactive polyurea (EPU) coating prepared by oxidative coupling polymerization is presented. Monitoring of the in situ chemical oxidation process for the reduced form of soluble EPU in N-met…
Herein we report the discovery of an in situ generated, highly active nanocatalyst for the room temperature dehydrogenation of dimethylamine-borane in water. The new catalyst system consisting of ruthenium(0) nanoparticles stabilized by the hydrogenphosphate anion can readily and reproducibly be formed under in situ c…
The formation of hybrid polyhedral silsesquioxane–polyamides, in the form of self-supporting or supported ultra-thin films, is presented. The thin films combine intrinsic local ordering of inorganic and organic constituents on the molecular scale with potentially infinite lateral macroscopic dimensions, are robust and…
The cooperative chemistry of polyoxometalates (POMs) and metal nanoparticles (NPs) still remains a relatively unexplored area of nanoscience despite showing remarkable potential and application in fields as diverse as catalysis and medicine. This Highlight article reviews the principal synthetic approaches used in the…
We focus on the functional role of small silver clusters in model hybrid systems involving peptides in the context of a new generation of nanostructured materials for biosensing. The optical properties of hybrids in the gas phase and at support will be addressed with the aim to bridge fundamental and application aspec…
The primary aims of this review article are (a) to develop the fundamental understanding of ME behavior in perovskite piezoelectric-spinel magnetostrictive composite systems, (b) to identify the role of composition, microstructural variables, phase transformations, composite geometry, and postsintering heat treatment…
Nanocomposites based on low‐density polyethylene (LDPE), containing 0.5, 1, 2, 3, and 5 wt% of nanoalumina, were prepared by melt‐mixing at 125°C and hot melt‐pressing to thin polymer film at 125°C. To enhance the interfacial interaction between alumina and LDPE, alumina surface was treated with silane which acts as c…
This study investigates the feasibility of synthesizing high-density transparent Ga(2)O(3)/SnO(2):Ga core-shell nanowires on a sapphire substrate at 1000 °C by VLS. The doping Ga concentrations are 0.46, 1.07, 2.30 and 17.53 atomic%. The XRD spectrum and HR-TEM reveal Ga(2)O(3) and SnO(2) as having monoclinic and tetr…
Nitrogen-doped graphene (N-G), in the form of a stable dispersion, a strong hydrogel and a macroporous aerogel, was synthesized by simultaneous nitrogen doping and reduction of graphene oxide with aqueous ammonia under mild conditions. The N content and thermal stability of the resultant samples proved to be high.
Well-dispersed, uniform Y2O3:Ln3+ (Ln3+ = Eu3+, Tb3+) hollow microspheres have been successfully prepared via a urea-assisted homogeneous precipitation method using polystyrene (PS) as templates, followed by a subsequent calcination process. X-Ray diffraction (XRD), scanning electron microscopy (SEM), transmission ele…
Two organic–inorganic hybrid hexa-CuII substituted sandwich-type arsenotungstates [Cu(en)2(H2O)]2 [Cu(en)2][Cu6(en)2(H2O)2(B-α-AsW9O34)2]·en·9H2O (1) and [Cu(dap)2]3[Cu6(dap)2(H2O)2(B-α-AsW9O34)2]·4H2O (2) (en = ethylenediamine, dap = 1,2-diaminopropane) have been hydrothermally prepared and structurally characterized…
A simple strategy to prepare AIE polymers is invented using an AIE initiator for atom transfer radical polymerization. The dual photoresponse by intramolecular charge-transfer and luminogen aggregation of the initiator is well-realized and even enlarged after polymerization, due to the linkage of polymer chains.
The present work reconsiders a classical and universally accepted concept of physical chemistry, the solubility parameter. Based on the insight derived from modern quantum chemical calculations, a new definition of solubility parameter is proposed, which overcomes some of the inherent restrictions of the original defi…
Many nanotechnological devices are based on implementing electrochemistry with plasmonic nanostructures, but these systems are challenging to understand. We present a detailed study of the influence of electrochemical potentials on plasmon resonances, in the absence of surface coatings and redox active molecules, by s…
Polypyrrole coated copper nanowires were synthesized in a one-pot manner in the presence of cupric precursor and pyrrole. They displayed ultra-high sensitivity as a potentiometric sensor with considerable environmental stability comparable to noble metals.
Controlled deposition of graphene in different orientations relative to the substrate is challenging and majority of existing deposition methods lead to sheets that lay flat on the substrate surface, limiting the potential applications in which the exposed sheet surface area and the atomically thin edges of graphene a…
An experimental and numerical analysis of the response of laminated composite plates under high-velocity impact loads of soft body gelatine projectiles (artificial birds) is presented. The plates are exposed to tensile and compressive preloads before impact in order to cover realistic loading conditions of representat…
We demonstrated that single-crystalline cobalt monoxide (CoO) hollow spheres and octahedra could be selectively synthesized via thermal decomposition of cobalt(II) acetylacetonate in 1-octadecene solvent in the presence of oleic acid and oleylamine. The morphologies and sizes of as-prepared CoO nanocrystals could be c…
