Thermoelectric Characteristics of Electrochemically Deposited Bi2Te3 and Sb2Te3 Thin Films of Relevance to Multilayer Preparation, Ma, Yi, Ahlberg, Elisabet, Sun, Ye, Iversen, Bo Brummerstedt, Palmqvist, Anders E. C.
The common approach of silver nanoparticles activation for surface enhanced Raman spectroscopy often exploits an addition of chloride ions, generally at low concentrations of about 0.1–10 mM in the final dispersion. For the first time, we report the applicability of a highly concentrated NaCl solution (final concentra…
The transmission spectra of microwave electromagnetic radiation interacting with a sample are used to determine the complex permittivity of a composite material based on a two-component epoxy adhesive having a certain volume fraction of inclusions in the form of multilayer carbon nanotubes or fine graphite particles.…
Ripening of AgCl nanoparticles with a bimodal size distribution has been carefully studied in ethylene glycol containing poly(vinyl pyrrolidone) (PVP) as capping molecules and at elevated temperatures (e.g., 160 °C). The resulting AgCl particles exhibit high uniformity in size and cube-tetrapod morphology that are sig…
This communication reports on the possibility to achieve the direct production of either carbamazepine crystals or carbamazepine–saccharin cocrystals from water/ethanol solvent mixtures by using membrane-based crystallization technology, by choosing the opportune initial conditions.
Polyaniline (PANI) film in the form of emeraldine salt (ES) doped with anthraquinone-2-sulfonate (AQS) was synthesized by a novel electrochemical doping-dedoping-redoping method on pre-activated spectroscopically pure graphite electrode surface. SEM showed the highly porous microstructure with sponge-like morphology o…
Determination of metal oxidation state under relevant working conditions is crucial to understand catalytic behaviour. The reduction behaviour of Pt and Re was evaluated simultaneously as a function of support and solvent in a pressurized reactor (autoclave). The bimetallic catalysts are used in selective hydrogenatio…
The three-dimensional organisation of a racemic core-twisted perylene bisimide (PBI) 1 and its pure atropo-enantiomers ((P)-1 and (M)-1) are compared in the condensed state to elucidate the impact of core chirality in such materials. Our studies revealed distinctive differences in the condensed state properties of the…
The BaZrxTi1-xO3 for 0⩽x⩽15 ceramics were prepared by a conventional solid state reaction method and were determined by an X-ray diffraction (XRD) and scanning electron microscopy (SEM) for crystallographic, surface morphological and compositional studies. A single phase with perovskite structure was identified in the…
Proton-coupled electron transfer (PCET) is emerging as an important new class of reactions and, over the past decade, great strides have been made in our understanding of them. PCET reactions are studied in many branches of chemistry and are omnipresent in biological processes. This book covers recent developments fro…
Stringent emission regulations around the world necessitate the use of high-efficiency catalytic converters in vehicle exhaust systems. Therefore, determining the optimum geometry of the honeycomb monolith structure is necessary. This structure requires a high surface area for treating gases while maintaining a low pr…
In the present study, magnetic nanoporous Cu(NPC)/(Fe,Cu)3O4 composites with tunable magnetism and excellent conductivity were fabricated by a facile one-step dealloying process. Three ternary Al–Cu–Fe alloys with different compositions were chosen as the precursors to carry out the dealloying process in a 20 wt% NaOH…
The unique physical and mechanical properties of polymer nanocomposites have been attributed to the interfacial interactions between the organic matrix and nanoscale particles. We demonstrate the potential to tune this interaction between poly(methyl methacrylate) (PMMA) and silica nanoparticles, as a function of eith…
Using a (2-pyridyl)ethylamine-appended carboxylate ligand a new cluster [Cu(II)(7)(L)(4)(μ(3)-OH)(2)(H(2)O)(2)(DMF)(2)][ClO(4)](4)·4H(2)O (1) [L(2-): N-{CH(2)CH(2)(2-pyridyl)}(CH(2)CH(2)CO(2))(2)] is synthesized, as a result of 'coordination-driven self-assembly'. The structure of 1 is unique and consists of a centros…
An integrated field-portable surface enhanced Raman scattering (SERS) sensing system has been developed and evaluated for quantitative analysis of energetics such as perchlorate (ClO(4)(-)) and trinitrotoluene (TNT) at environmentally relevant concentrations and conditions. The detection system consists of a portable…
A microcosm experiment was carried out in order to test the effect of the herbicide metolachlor on river periphytic diatoms and to find potential diatom bioindicators of contamination. Effects were investigated at different biological organization levels (biofilm, diatom community, population and individual levels). T…
Donor-doped strontium titanate represents an interesting class of materials for novel applications in solid oxide fuel cells. We have prepared three different stoichiometries, Sr1−xCexTiO3±δ, Sr1−1.5xCexTiO3±δ and Sr1−2xCexTiO3±δ (0.05< x <0.15) to examine structural properties when prepared in air. We have found that…
Biopolymers are important natural multifunctional macromolecules for biomimetic and bio-inspired advanced functional material design. They are not only simple dispersants for carbon nanotube stabilization as they have been found to have specific interactions with carbon nanotubes. Their molecular activity, orientation…
Stable colloidal suspensions of single-walled carbon nanotubes (SWCNT) and magnetite-labeled SWCNT (SWCNT/Fe3O4) in thermotropic liquid crystal 4-(trans-4′-n-hexylcyclohexyl)isothiocyanatobenzene (6CHBT) were investigated. The presence of the magnetite in SWCNT/Fe3O4 product has been checked with infrared spectroscopy…
Environmental, health, and safety (EHS) concerns are receiving considerable attention in nanoscience and nanotechnology (nano) research and development (R&D). Policymakers and others have urged that research on nano's EHS implications be developed alongside scientific research in the nano domain rather than subsequent…
