Enhanced Room-Temperature Ionic Conductivity of NaCB11H12 via High-Energy Mechanical Milling

Laura Piveteau, Claudia Esther Avalos, Radovan Cerny, Matteo Brighi

The body-centered cubic (bcc) polymorph of NaCB11H12 has been stabilized at room temperature by highenergy mechanical milling. Temperature-dependent electrochemical impedance spectroscopy shows an optimum at 45-min milling time, leading to an rt conductivi ...

Simultaneous Selective Area Growth of Wurtzite and Zincblende Self-Catalyzed GaAs Nanowires on Silicon

Anna Fontcuberta i Morral, Lucas Güniat, Valerio Piazza, Wonjong Kim, Vladimir Dubrovskii

Selective area epitaxy constitutes a mainstream method to obtain reproducible nanomaterials. As a counterpart, self-assembly allows their growth without costly substrate preparation, with the drawback of uncontrolled positioning. We propose a mixed approac ...

Molecular basis for inhibition of adhesin-mediated bacterial-host interactions through a peptide-binding domain

Corey Alfred Stevens

Infections typically begin with pathogens adhering to host cells. For bacteria, this adhesion can occur through specific ligand-binding domains. We identify a 20-kDa peptide-binding domain (PBD) in a 1.5-MDa RTX adhesin of a Gram-negative marine bacterium ...

Comparing crystal structures with symmetry and geometry

Anirudh Raju Natarajan

Measuring the similarity between two arbitrary crystal structures is a common challenge in crystallography and materials science. Although there are an infinite number of ways to mathematically relate two crystal structures, only a few are physically meani ...

Crystal Structures of AlCr2 and MoSi2: Same Structure Type vs. Different Bonding Pattern

Philip Johannes Walter Moll

In a joint effort utilizing modified sample preparation, microscopy, X-ray diffraction and micro-fabrication, it became possible to prepare single crystals of the "hidden" phase AlCr2. High-resolution X-ray diffraction analysis is described in detail for t ...

Novel photoelectric material of perovskite-like (CH3)(3)SPbI3 nanorod arrays with high stability

Mohammad Khaja Nazeeruddin, Wei Liu, Ruiyuan Hu, Shanshan Xiao

Organometallic halide perovskite materials make great achievements in optoelectronic fields, especially in solar cells, in which the organic cations contain amine components. However, the amine with N-H bonds is easily hydrolyzed with moisture in the air, ...
