Iron oxide nanoparticles (IONPs) occupy a privileged position among magnetic nanomaterials with potential applications in medicine and biology. They have been widely used in preclinical experiments for imaging contrast enhancement, magnetic resonance, immunoassays, cell tracking, tissue repair, magnetic hyperthermia a…
Considering that ZnAl2O4 spinel has two different sites (octahedral and tetrahedral) and its properties change with dopant ion distribution among these two sites; ZnAl2O4 doped with varied concentrations of Fe(3+) was synthesized by a low temperature sol-gel combustion method. Phase purity and structural investigation…
Highly-dispersed Fe 3 O 4 @ZrO 2 yolk–shell structures with a ZrO 2 shell of homogeneous shell thickness was successfully prepared via a polymer surfactant (hydroxypropyl cellulose) assisted sol–gel method.
Large quantities of narrow graphene nanoribbons with edge-incorporated nitrogen atoms can be synthesized via Yamamoto coupling of molecular precursors containing nitrogen atoms followed by cyclodehydrogenation using Scholl reaction.
This article describes the best corrosion inhibition behavior and adsorption of newly synthesized amino tetrazole using electrochemical and computational methods.
Covalently bonded graphene oxide/polyurethane composites with significant mechanical reinforcement and thermally healable capability were developed via in situ polymerization based on Diels–Alder chemistry.
Schematic and digital photos of the preparation for water-soluble nitrogen (N) and sulfur (S) co-doped graphene quantum dots (NS-GQDs). Sulfur enhances the photoluminescence of NS-GQDs.
Di-zinc and di-magnesium catalysts for the ring-opening copolymerization of phthalic anhydride and cyclohexene oxide are presented. They are applied in terpolymerizations to prepare block copoly(ester-carbonates).
A new idea to understand the macromolecular motion occurring along the thermal relaxations of polystyrene (PS) and PS-barium titanate composites is proposed. Detailed analysis of PS infrared bands provides a better knowledge of the factors affecting polymer dynamics. Average spectral positions and integrated absorbanc…
Since the revolutionary discovery that phospholipids can form closed bilayered structures in aqueous systems, liposomes have become a very interesting topic of research. Because of their versatility and amazing biocompatibility, the use of liposomes has been widely accepted in many scientific disciplines. Their applic…
Pomelo peel as biomass-derived porous activated carbon is used for the preparation of a high energy density symmetric supercapacitor.
Advances in the fundamental understanding of alkane activation on oxide surfaces are essential for developing new catalysts that efficiently and selectively promote chemical transformations of alkanes. In this tutorial review, we discuss the current understanding of alkane activation on crystalline metal oxide surface…
Triblock copolymers having glassy PMMA blocks and dynamic hydrogen bonding blocks were synthesized by sequential atom transfer radical polymerization (ATRP). The dynamic triblock copolymers self-assemble into nanocomposite materials exhibiting a combination of mechanical strength, toughness, and self-healing capabilit…
Electrospun polyamide 6 (PA 6) and polyamide 6/6 (PA 6/6) nanofibers were produced in order to investigate their experimental characteristics with the goal of obtaining filtration relevant fiber media. The experimental design model of each PA nanofibers contained the following variables: polymer concentration, ratio o…
We report a unique example of polymorphism-dependent and piezochromic fluorescence, based on 2-(anthracen-9-yl)-4,5-diphenyl-1 H -imidazole.
Selective and preferential deposition of Cr on segregated SrO on the surface of LSCF cathodes of solid oxide fuel cells.
Carbon formation during co-electrolysis of H 2 O and CO 2 in Ni-YSZ supported Solid Oxide Electrolysis Cells (SOECs) may occur, especially at high current density and high conversion.In order to evaluate the carbon formation limits, five galvanostatic tests were performed in this work at electrolysis current densities…
Cobalt has been widely used as the main component of catalysts for the hydrolysis of sodium borohydride NaBH4 and, to a lesser extent, for the hydrolysis of ammonia borane NH3BH3. Though active in these reactions, the cobalt-based catalyst generally suffers from rapid deactivation. As emphasized in a perspective paper…
Oleic acid-capped NaYF4:Yb(3+)/Er(3+) upconversion nanocrystals (UCNCs) with different sizes and crystalline phases were prepared, and their temperature-dependent upconversion luminescence (UCL) and dynamics were studied. It is interesting to observe that the temperature-dependent behavior of UCL for the β-phase (25 n…
Carbon Nanotubes (CNTs) are the allotropes of carbon which belong to the fullerene structural family. These are cylindrical structures with at least one end closed with a buckyball structure hemisphere. They are few nano meter in diameter and have tensile strength of ∼63 GPa and young's modulus of ∼1TPa. On the basis…
