Designing a Bernal Spiral from Patchy Colloids

John W. R. Morgan、Dwaipayan Chakrabarti、Nicolas Dorsaz 等 4 位作者2013-01-24ACS Nano

A model potential for colloidal building blocks is defined with two different types of attractive surface sites, described as complementary patches and antipatches. A Bernal spiral is identified as the global minimum for clusters with appropriate arrangements of three patch-antipatch pairs. We further derive a minimal…

Hysteresis modeling of the grain-oriented laminations with inclusion of crystalline and textured structure in a modified Jiles-Atherton model

A. P. S. Baghel、S.V. Kulkarni2013-01-24Journal of Applied Physics

Grain-oriented (GO) laminations owing to their crystalline and textured structure exhibit strong anisotropy in magnetic characteristics. GO laminations generally display highly steep, gooseneck, and narrow waist rolling direction (RD) hysteresis loops and complex-shaped transverse direction (TD) curves. The original J…

Quantum-Dot-Sensitized Solar Cells: Understanding Linker Molecules through Theory and Experiment

Johannes T. Margraf、Andrés Ruland、Vito Sgobba 等 5 位作者2013-01-24Langmuir

We have investigated the role of linker molecules in quantum-dot-sensitized solar cells (QDSSCs) using density-functional theory (DFT) and experiments. Linkers not only govern the number of attached QDs but also influence charge separation, recombination, and transport. Understanding their behavior is therefore not st…

Recyclable synthesis, characterization, and antimicrobial activity of chitosan‐based polysaccharide composite materials

Chieu D. Tran、Simon Duri、April L. Harkins2013-01-24Journal of Biomedical Materials Research Part A

We have successfully developed a simple and totally recyclable method to synthesize novel, biocompatible, and biodegradable composite materials from cellulose (CEL) and chitosan (CS). In this method, [BMIm(+) Cl(-) ], an ionic liquid (IL), was used as a green solvent to dissolve and synthesize the [CEL+CS] composites.…

Incorporation of Amphiphilic Cyclodextrins into Liposomes as Artificial Receptor Units

Ulrike Kauscher、Marc C. A. Stuart、Patrick Drücker 等 5 位作者2013-01-24Langmuir

In this article, we describe the introduction of amphiphilic β-cyclodextrins into liposomes to act as artificial receptor units. Using dynamic light scattering, dye encapsulation, and cryogenic transmission electron microscopy, we show that amphiphilic β-cyclodextrins can be mixed in any proportion with a typical mixt…

Absolute cross sections for dissociative electron attachment and dissociative ionization of cobalt tricarbonyl nitrosyl in the energy range from 0 eV to 140 eV

Sarah Engmann、Michal Staňo、Péter Papp 等 6 位作者2013-01-24The Journal of Chemical Physics

We report absolute dissociative electron attachment (DEA) and dissociative ionization (DI) cross sections for electron scattering from the focused electron beam induced deposition (FEBID) precursor Co(CO)(3)NO in the incident electron energy range from 0 to 140 eV. We find that DEA leads mainly to single carbonyl loss…

This paper deals with several properties of calcite crystals. First, the solvated surface energies at 0 K of the {101̅4}, {101̅0}, {112̅0}, {011̅8}, {011̅2}, {0001}, and {213̅4} forms were determined by means of the COSMIC method. We find that the presence of water reduces by ∼7–14% the dry surface energy at 0 K, in a…

Membrane hydrophone measurement and numerical simulation of HIFU fields up to developed shock regimes

O. V. Bessonova、Volker Wilkens2013-01-24IEEE Transactions on Ultrasonics Ferroelectrics and Frequency Control

For the characterization of high-intensity focused ultrasound (HIFU) fields, hydrophone measurements should be performed in water in the whole range of the radiated power; however, cavitation occurs at high output, leading to the destruction of the hydrophone. To avoid this problem, a new hydrophone with additional pr…
