The mechanism for the syntheses of inorganic framework materials based solely on polyoxometalate Keggin clusters has been examined and their electronic properties have been investigated. The assembly of the modular network compounds with the molecular formula (C 4 H 10 NO) n [W 72 M 12 O 268 X 7 ] (with the heteroatom…
In this paper we report the use of plasma-enhanced chemical vapor deposition (PECVD) for the simultaneous deposition and copolymerization of an amino acid with other organic and inorganic monomers. We investigate the fundamental effects of plasma-enhanced copolymerization on different material chemistries in stable ul…
The possibility of tuning the electronic properties of graphene by tailoring the morphology at the nanoscale or by chemical functionalization opens interesting perspectives towards the realization of devices for nanoelectronics. Indeed, the integration of the intrinsic high carrier mobilities of graphene with function…
The morphology and ontogenetic allometric trends of several taxa in the Pinnatae group of Surirella were studied using traditional morphometrics, landmark-based shape analysis, and light and electron microscopy. We investigated separately two groups of species: the first consisted of S. brebissonii Krammer & Lange-Ber…
We use density functional theory to study the properties of low index flat faces (i.e., not having steps) of lanthanum oxychloride LaOCl. We calculate the surface energies and the energies to make oxygen and chlorine vacancies on the surface by producing 1 / 2 O 2 or 1 / 2 Cl 2 in the gas phase. We find that the elect…
One-dimensional nanostructures such as ZnTe, CdTe, Bi(2)Te(3) and others have attracted much attention in recent years for their potential in thermoelectric devices among other applications. A better understanding of their mechanical properties is important for the design of devices. A combined experimental and comput…
Chiral polyoxometalates (POMs) have been a hot topic because of their potential applications in the fields of stereoselective catalysis, bio-simulation, sensing, nonlinear materials, and medicine. In view of the extensive work on chiral POMs, four parts are included in this review to give a broad overview on recent de…
Using zirconium propoxide as the precursor, a new method combining the advantages of electrospinning and sol–gel approaches is set up to facilely fabricate zirconia (ZrO2) nanofibers with controllable chemical and morphological structures in batch size on a standard electrospinning equipment. Interestingly, zirconia (…
Half-Heusler (HH) alloys constitute an important class of materials that exhibit promising potential in high-temperature thermoelectric (TE) power generation. In this work, we synthesized Zr1−x Yb x NiSn (x = 0, 0.01, 0.02, 0.04, 0.06 and 0.10) HH alloys using a time-efficient levitation melting and spark plasma sinte…
Glass fiber-reinforced polymer (GFRP) composite with neat epoxy matrix and GFRP nanocomposite with epoxy–organoclay nanocomposite matrix were prepared. Their tensile properties degradation at elevated temperatures and in alkaline as well as freeze–thaw cycling environments was studied by performing the uniaxial tensio…
A biological approach for degumming bamboo substrates has been assessed. The ability of various commercially available enzymes, including cellulase, xylanase, pectinase and mannanase, to hydrolyze bamboo powders was investigated. In addition, a commercial cellulase preparation was applied onto bamboo fibre bundles obt…
Multilayered thin-film doped silica structures are experimentally demonstrated as an effective tool to enhance the second-order nonlinear properties induced in thermally poled glass devices. A 204-fold improvement is obtained in the second harmonic generated (SHG) in a poled structure with a 3 μm-thick multilayered st…
Assessment of Stress Corrosion Cracking on Pipeline Steels Weldments Used in the Petroleum Industry by Slow Strain Rate Tests
Self-assembled silver nanoparticle (NP) arrays were produced by deposition at glancing angles on transparent stepped Al2O3 templates. The evolution of the plasmonic resonances has been monitored using reflection anisotropy spectroscopy (RAS) during growth. It is demonstrated that the morphology of the array can be tai…
Surface-enhanced resonance Raman scattering (SERRS) spectroscopy is a highly sensitive optical technique capable of detecting multiple analytes rapidly and simultaneously. There is significant interest in SERRS detection in micro- and nanotechnologies, as it can be used to detect extremely low analyte concentrations i…
This paper reports the in vitro degradation of three-dimensional, highly porous tissue engineering scaffolds and non-porous thin films based on poly (L-lactide) (PLLA) biopolymers. The tissue engineering scaffolds were produced through the emulsion freezing/freeze-drying technique. The nonporous thin films were produc…
We aim to study magnetic and thermal behaviors of some melamine cored macromolecular Schiff base complexes. In this context, tripodal ligands were synthesized by reacting melamine with 4-carboxybenzaldehyde or 4-hydroxybenzaldehyde. Then, 16 new trinuclear Fe(III), Cr(III), Mn(III), and Al(III) complexes were synthesi…
Abstract Graphene has great potential in electrochemical storage applications for supercapacitors owing to its high conductivity, large surface area, and the economical feasibility in producing it. The main issue that faces graphene nanomaterials in this application is that they tend to restack, thus decreasing the ac…
