Coarse-grained Direct Phasing Method for Protein X-ray Crystallography
X-ray crystallography is the most powerful method to obtain the structural of biological molecules if the “phase problem” can be solved for the molecules under study. The phase problem arises from the loss of phase information in diffraction experiment. In all the solutions of the phase problem, the direct method is t…

Intrinsic shape analysis of X-ray diffraction using Stokes deconvolution
A deconvolution algorithm is proposed for X-ray diffraction profile analysis. The stability of the algorithm and the influence of the regularization parameter in the deconvoluted results were investigated with respect to the full width at half maximum (FWHM) and the signal to noise ratio. Reliability of the deconvolut…

Síntese e caracterização de óxidos ternários nanoestruturados puros e dopados
Neste estudo, foi analisada a formacao da estrutura perovskita do titanato de estroncio dopado com samario (STSm) e com gadolinio (StGd) a 1%, 3% e 5%. Para a obtencao dos oxidos ternarios utilizou-se o metodo dos precursores polimericos, uma variacao do metodo sol gel proposto por Pechini, por entender-se se tratar d…
Weak symmetry breaking in two dimensional topological insulators
We show that there exist two dimensional (2D) time reversal invariant fractionalized insulators with the property that both their boundary with the vacuum and their boundary with a topological insulator can be fully gapped without breaking time reversal or charge conservation symmetry. This result leads us to an appar…
n-TiO 2 /p-Si anisotype semiconductor heterojunction structure
The dominating current-transport mechanisms were established: multistep tunnel-recombination via surface states at the metallurgical interface TiO2/Si under low forward bias; the dominating mechanism of charge carriers' transport is tunneling at forward bias V > 0.6 V. The reverse current through the heterojunctions u…
A Novel Heterobimetallic [Mg(II)-Sn(IV)]-μ-oxoisopropoxide and Its β-Diketonates: Synthesis, Analytical and Pyrolysis Studies
In the present study, a novel heterobimetallic [Mg(II)-Sn(IV)]-μ-oxoisopropoxide [MgO2Sn2(OPri)6] and its β-diketonates have been synthesized and characterized. The parent compound has been synthesized by the thermal condensation of magnesium acetate and tin(IV) isopropoxide. The isopropoxy substitution reactions of μ…
Inside Back Cover: Photosensitization of Singlet Oxygen and In Vivo Photodynamic Therapeutic Effects Mediated by PEGylated W18O49 Nanowires (Angew. Chem. Int. Ed. 47/2013)
W18O49 nanowires can sensitize the formation of singlet oxygen upon irradiation with near-infrared (NIR) light. In their Communication on page 12332 ff., K. C. Hwang and co-workers describe the complete destruction of solid tumors in mice by W18O49-nanowire-mediated photodynamic therapy (PDT). This effect was not achi…
Drug Delivery: Transdermal Delivery Devices: Fabrication, Mechanics and Drug Release from Silk (Small 21/2013)
A high aspect ratio microneedle biomedical device fabricated from aqueous silk protein solution using micromolding techniques is reported by D. L. Kaplan and co-workers on page 3704. The device is formed under ambient conditions, which allows the inclusion of sensitive pharmaceuticals or other bioactive compounds duri…

Synthesis and Physicochemical Properties of Silicon‐Terminated Octyl/Decyl Polyethylene Oxide as Novel Low‐Foam Penetrating Agents
Abstract Low‐foam penetrating agents have been sought after for many industrial applications. In this paper, we were aiming at a low‐foam penetrating agent with excellent wetting ability and hydrolysis resistance, various silicon‐terminated penetrating agents were designed and synthesized starting from a popular comme…
Spin and valley polarization dependence of resistivity in two dimensions
We demonstrate that spin polarization and valley polarization have quantitatively similar effects on the resistivity of a two-dimensional electron gas in a silicon-on-insulator quantum well. In so doing, we also examine the dependence on disorder, leading to a coarse but global phenomenology of how the resistivity dep…
