Hydrogen plays an essential role during the in situ assembly of tailored catalytic materials, and serves as key ingredient in multifarious chemical reactions promoted by these catalysts. Despite intensive debate for several decades, the existence and nature of hydrogen-involved mechanisms - such as hydrogen-spillover,…
Multi-walled carbon nanotubes MWNTs were oxidized by using acid and base Piranha reagent. The acid reagent consists of mixture solution 3:1 H 2 SO 4 :H 2 O 2 , while the base reagent was NH 4 OH:H 2 O 2 . We will discuss our results by using XRD diffraction to also study the effect of oxidizing agents on the surface b…
We proposed an electrochemical route to functionalize graphene nanosheets (GNs) directly from a natural graphite electrode in the presence of sulfate ions under constant-voltage and constant-current models.
The electronic structure of FeSe, the simplest iron-based superconductor (Fe-SC), conceals a potential \nof dramatic increase of Tc that realizes under pressure or in a single layer film. This is also the system where \nnematicity, the phenomenon of a keen current interest, is most easy to study since it is no…
The processes of machining have vital influence on the operating properties of machine parts because they ensure the formation of the required geometrical structure of the working surfaces and the condition of the top layer. In this paper the influence of emulsion mist parameters on Ra, Rz and RSm surface roughness pa…
The present work describes the synthesis of zinc ferrite nanoparticles by a chemical coprecipitation method and its surface modification with poly(diallyldimethylammonium chloride) (PDDA), tetramethylammonium hydroxide (TMAOH) and poly(ethylene glycol) (PEG). The effect of coating on the colloidal stability of obtaine…
Polymers and their hybrid composites are of significant interest to material scientists, owing to fascinating end product applications. The ever increasing demand for polymer based composite systems has imposed the scientific community to design, develop and characterize novel hybrid composites for advanced material a…
Novel CuS/ZnS hetero-nanowires were synthesized through a template-free chemical solution method. The improved photocatalytic activities are attributed to the p–n heterojunctions, one-dimensional nanostructure and large specific surface area.
H-NMR and GC-MS analyses of the colorless end products of Rhodamine B destruction provide further insight into the reaction mechanism. The complete mineralization of the decolorized end product of degradation was evaluated with TOC analysis. The results indicate the potential for using multi metal incorporated LDH in…
Construction of ultrathin multilayer polymer nanocomposite films with tailor-made properties have been achieved to suppress incoming EM radiation with 52 dB shielding effectiveness at 18 GHz.
Macro-thermal cloaking is typically produced by coordinate transformations, but this method is unsuitable for nanostructures. We designed a graphene-based nanoscale thermal cloak using a novel mechanism of phonon localization. The nanocloak in graphene was produced via the chemical functionalization of hydrogen, methy…
Biocompatible organosilane surface modification of cerium oxide nanoparticles (CNPs) open promising therapeutic avenues in nanomedicine.
The increasing demand for energy and growing concerns for environmental issues are promoting the development of organic electrode materials. Among these, conjugated carbonyl compounds (CCCs) represent one of the most attractive and promising candidates for sustainable and eco-benign energy storage devices in the comin…
A comparison of two similar copper based compounds presenting strikingly different optical properties and preparation of luminescent mechanochromic coatings are reported.
Tin (Sn) anode active particles were electrochemically lithiated during simultaneous imaging in a scanning electron microscope. Relationships among the reaction mechanism, active particle local strain rate, particle size, and microcrack formation are elucidated to demonstrate the importance of strain relaxation due to…
The growth of polymer brushes from a variety of methacrylate monomers was accomplished using UV light as a polymerization trigger.
3-glycidoxypropyl-trimethoxysilane (GPTMS) functionalized graphene oxide (GO) was used to synthesize graphene-based film for corrosion protection of AA2024-T3 aluminum alloy. GO covalently reacted with the silanol group from the hydrolyzed GPTMS monomer, forming silane functionalized GO (silane-GO) linked by C-O-Si co…
A very high dielectric constant of Nb doped titania is observed due to both the interfacial effect and formation of complex defect dipoles.
Biosynthesis of palladium nanoparticles (PdNPs) is considered an efficient and green method for catalytic applications.
Detailed characterizations, including rheological studies of new triazolyl arabinoside based organogelators which are effective for PSOG of crude-oil are reported.
