Vitaliy Datsyuk, a Svitlana Trotsenko and Stephanie Reich a Freie Universität Berlin, FB Physik, Institut für Experimental Physik, Arnimallee 14, 14195 Berlin, Germany Highly thermally conductive carbon nanotube/polybenzimidazole polymer nanofiber composites were produced by core-shell electrospinning. The in-plane thermal conductivity increased by factor of 50 for 1.94 %wt. carbon nanotubes in...

The data presented in this article are related to a research article entitled 'Highly efficient solar-driven photocatalytic degradation on environmental pollutants over a novel C fibers@MoSe2 nanoplates core-shell composite' (Wang et al., 2018) [1]. In this article, we report original data on the synthesis processes optimization of the proposed composite together with its formation mechanism. T...

A semiempirical shell-correction method including ellipsoidal deformations is used to determine binding energies of open-shell, unpolarized HeN clusters. Shell effects, shapes, and other ground-state properties ~like the chemical potential! are determined. HeN clusters are found to be substantially less deformed due to their relatively high surface energy as compared to that of alkali-metal clu...

Carapace, the protective shell of a freshwater snapping turtle, Chelydra serpentina, shields them from ferocious attacks of their predators while maintaining light-weight and agility for a swim. The microstructure and mechanical properties of the turtle shell are very appealing to materials scientists and engineers for bio-mimicking, to obtain a multi-functional surface. In this study, we have ...

Composite core/shell fiber structures loaded with the antiproliferative drugs paclitaxel or farnesylthiosalicylate (FTS) were developed and studied. The latter is a specific nontoxic Ras inhibitor with a mild hydrophobic nature, which can also be used for local cancer treatment and stent applications. The fibers were composed of a dense polyglyconate core and a porous drug-loaded poly(D,L-lacti...

Nanotechnology approaches offer the potential for creating new optical imaging agents with unique properties that enable uses such as combined molecular imaging and photo-thermal therapy. Ideal preparations should fluoresce in the near-infrared (NIR) region to ensure maximal tissue penetration depth along with minimal scattering and light absorption. Due to their unique photophysical properties...

No. dima4496 Beamline(s): X22B Like many other biomineralized materials, nacre (mother-of-pearl) has a complicated, hierarchical microstructure with organization on length scales ranging from Ångstroms to microns. For example, the nacre of Red Abalone (Haliotis rufescens) is composed of bricks of aragonite (CaCO3) “mortared” in an organic composite. The crystallography of the mineral component ...

Numerical simulations of composite structures are generally performed using multi-layered shell elements in the context of the finite elements method. This strategy has numerous advantages like a low computation time and the capability to reproduce the comportment of composites in most of cases. The main restriction of this approach is that they require an approximation of the comportment in th...

TiO₂-CdO composite rods were synthesized through a hydrothermal method and sputtering thin-film deposition. The hydrothermally derived TiO₂ rods exhibited a rectangular cross-sectional crystal feature with a smooth surface, and the as-synthesized CdO thin film exhibited a rounded granular surface feature. Structural analyses revealed that the CdO thin film sputtered onto the surfaces of the TiO...

Two tungsten disulfide (WS₂)-based core-shell nanocomposites were fabricated using readily available reagents and simple procedures. The surface was pre-treated with a surfactant couple in a layer-by-layer approach, enabling good dispersion of the WS₂ nanostructures in aqueous media and providing a template for the polymerization of a silica (SiO₂) shell. After a Stöber-like reaction, a conform...
