Exposure of humans and other organisms to nanomaterials is increasing exponentially. It is important, but difficult, to predict the biological consequences of these exposures. We hypothesized that the unique chemical properties that make nanoparticles useful might also be the key in predicting their biological impact.…
Abstract A simple and scalable method to fabricate graphene‐cellulose paper (GCP) membranes is reported; these membranes exhibit great advantages as freestanding and binder‐free electrodes for flexible supercapacitors. The GCP electrode consists of a unique three‐dimensional interwoven structure of graphene nanosheets…
Abstract Sulfate‐reducing bacteria (SRB) are shown to be common inhabitants of oil reservoirs. Desulfovibrio caledoniensis isolated from a production well was used in this study. After an incubation period of 1 month with the SRB culture, two layers of corrosion products with different compositions were detected on th…
Abstract Octadecylamine (ODA) film assisted with the preferential adhesion of poly‐DOPA was prepared on copper substrates by dip‐coating method. The DOPA self‐polymerized and adhered membrane was firmed to the copper substrate in mild aqueous alkaline environments. By immersing the substrate coated with poly‐DOPA in i…
Abstract Two new ferrocene–porphyrin derivatives, namely 5,15‐bis(ferrocenyl)‐10,20‐bis(4‐nitrophenyl)porphyrin ( 1 ) and its nickel congener 5,15‐bis(ferrocenyl)‐10,20‐bis(4‐nitrophenyl)porphyrinatonickel ( 2 ) have been designed, synthesized, and characterized. Their self‐assembly properties have been comparatively…
Encapsulation of inorganic nanoparticles within oligomeric protein cages can provide a multivalent approach for the synthesis of biocompatible nanomaterials by combining the nanoparticle-forming catalytic abilities of the cage interior with the biointeractive exterior surface of the cage. Protein cages provide more th…
Protonic ceramics have unique transport properties that make them suitable for applications in intermediate temperature fuel cells and steam electrolyzers, hydrogen separation membranes, and various membrane reactors for chemical synthesis. Since the discovery of ceramic proton conductors more than twenty years ago, a…
We present the results of an extensive 3D Brownian dynamics simulation of the self-assembly of colloidal particles for a short-range attractive model that is quenched below its metastable critical point. In particular, results are obtained in the small-volume-fraction, low-temperature region in which we find so-called…
A fully implicit two-dimensional moving-mesh finite element simulation model, without symmetry assumption, recently developed by the present authors was used to study the cause of anomalous reversed temperature dependence of diffusional solidification completion time, t f, during brazing of single crystal nickel-based…
Research on postprocessing of glass fiber–reinforced anionic polyamide-6 (APA-6) composites was performed in order to optimize the processing time. The two main points of investigation were the cure time and the annealing cycle. It was shown that the optimal mechanical properties (short-beam strength) coincided with t…
Abstract The well dispersed multiwalled carbon nanotube (MWCNT)/epoxy composites were prepared by functionalization of the MWCNT surfaces with glycidyl methacrylate (GMA). The morphology and thermal properties of the epoxy nanocomposites were investigated and compared with the surface characteristics of MWCNTs. GMA‐gr…
Abstract (6‐Methoxy‐2‐oxo‐2 H ‐naphtho[1,2‐ b ]pyran‐4‐yl)methyl esters of valine or phenylalanine as model bifunctional molecules were synthesised to assess its applicability as a photocleavable protecting group for solution phase organic synthesis and in caging applications at longer wavelengths. The behaviour of th…
Abstract Intermetallic compounds have been investigated over several decades for their interesting structural and physical properties, including magnetism and superconductivity. Among these, metal pnictides and chalcogenides of transition metals show diversity of bonding ranging from appreciable covalency to metal–met…
Abstract Novel bis(azo) dyes were successfully prepared from the coupling of either natural cardanol or its hydrogenated derivative with a series of diazotized aromatic amines and diamines. These new dyes were fully characterized by NMR, infrared and UV–visible spectroscopy and mass spectrometry. The dyes are highly s…
Synthesis of Carbon Nanomaterials in a Swirled Floating Catalytic Chemical Vapour Deposition Reactor for Continuous and Large Scale Production
Carbon Nanotubes -Growth
Abstract The interest in the study of oligomers has been motivated mainly because of their solubility in common solvents and also their capacity to be crystallized, which allowed for chemical processing leading to important applications in the area of material sciences. In this work, we carried out an investigation of…
Carbon Nanotubes in Biomedicine and Biosensing 137 Noncovalent interactionThe noncovalent approach via electrostatic interaction, Van der Waals force, or π-π stacking is a feasible immobilization method for biomolecules.Particularly, it is promising for improving the dispersion proteins of CNTs without destructing of…
We have synthesized Tl 2 ZrTe 3 at elevated temperatures starting from the elements. Tl 2 ZrTe 3 adopts a cubic structure, space group P 2 1 3 with a unit cell parameter of a = 19.118(1) Å ( Z = 36). All Tl and Zr atoms are octahedrally (distorted) coordinated by Te atoms. One out of 11 crystallographically distinct T…
