The cognate docking performance of Glide was evaluated using the Astex diverse set. The standard Glide SP protocol obtained a 85.7 % success rate when the shape similarity cutoff was set to 0.625. The analysis of docking failures pointed out that, when the SiteMap binding site exposure is less than 0.491, 51 out of 52…
Catalysis Catalysts made from atomically dispersed metal atoms on oxide supports can exhibit very high per atom activity. However, the low loadings needed to prevent metal particle formation can limit overall performance. Liu et al. stably decorated titanium oxide nanosheets with relatively high
In the present study, polycrystalline samples of -rich binary alloys with stoichiometry 1- ; x < 0.15; were prepared by mixing appropriate amounts of the metallic elements which were arc-melted on a water-cooled hearth under high-purity argon atmosphere.The X-ray diffraction patterns of the as cast alloys and heat tre…
Parkinson's Disease The protein α-synuclein (α-syn) accumulates in the brains of people with Parkinson's disease (PD), forming fibrils that are a hallmark of the disease. Tuttle et al. used sophisticated solid-state nuclear magnetic resonance techniques to determine a high-resolution three-dimensional structure of α-s…

In this paper, we indicate a new way to define coordinates for the tiles of the tilings $\{p,3\}$ and $\{p$$-$$2,4\}$ where the natural number $p$ satisfies $p\geq 7$.
Abstract The Co doped amorphous carbon films (a-C:Co), deposited by pulsed laser deposition, show p-n and ohmic contact characteristics with n-type low resistivity GaAs (L-GaAs) and semi-insulated high-resistivity GaAs (S-GaAs). The photosensitivity enhances for a-C:Co/L-GaAs, while inverse decreases for a-C:Co/S-GaAs…

Graphene is a two dimensional material which has combination of unique mechanical, electrical and optical properties. Due to the unique properties of graphene, it has potential for several applications such as radio frequency applications and ultrafast photodetectors. Reducing contact resistance of metal-graphene is i…

The dendritic polymers (dendrimers) are perspective nanocontainers for transportation of anticancer drugs into cells and a controlled release of the delivered substances. However, the combined effect of ionizing radiation and dendrimers loaded with anticancer drugs has been poorly studied and is the aim of this resear…
A evolução sistemática dos materiais ortodônticos impulsiona uma contínua inovação tecnológica com o objetivo de potencializar a biocompatibilidade dos tratamentos, tornando-os constantemente mais simples e eficientes. Mas, apesar de todo conteúdo publicado em revistas especializadas sobre os bráquetes autoligáveis (A…
This report describes the third set of tests (the “DCLa shaker tests”) of an instrumented surrogate PWR fuel assembly. The purpose of this set of tests was to measure strains and accelerations on Zircaloy-4 fuel rods when the PWR assembly was subjected to rail and truck loadings simulating normal conditions of transpo…
Copper(I) hydridotrispyrazolylborate complexes were synthesized and analyzed as potential candidates for highly sensitive ethene detection. The best complexes were selected and used as sensitizers for extremely sensitive graphene-based ethene gas sensors.
Hydrazone-activated polymers with a consistent degree of polymerization but with different post-polymerization functionalization were employed as scaffolds for siRNA delivery. In their Communication on page 7492 ff., J. Montenegro, F. Fernandez-Trillo et al. report the preparation of amphiphilic polymers and their eva…
In this study, we investigated the effect of spacer and buffer layers on the blocking temperature TB of the perpendicular exchange bias of thin Cr2O3 films, and revealed a high TB of 260 K for 20-nm-thick Cr2O3 thin films. By inserting a Ru spacer layer between the Cr2O3 and Co films and changing the spacer thickness,…
This paper presents fabrication, measurement and modelling results for a metal-dielectric-metal metasurface absorber for solar thermal applications. The structure uses amorphous carbon as an inter-layer between thin gold films with the upper film patterned with a 2D periodic array using focused ion beam etching. The p…
Experimentally produced graphene sheets exhibit a wide range of mobility values. Both extrinsic charged impurities and intrinsic ripples (corrugations) have been suggested to induce long-range disorder in graphene and could be a candidate for the dominant source of disorder. Here, using large-scale molecular dynamics…
We investigate the superconductivity in the $t-J-U$ model within a slave-spin formalism. We show that the BCS mean-field theory implemented with the slave spin formalism naturally predicts two distinct gaps which are the pairing gap of the spinons $Δ_f$ and the Cooper pairing gap of the electrons $Δ_{SC} = ZΔ_f$, wher…
