GIXSGUI is a MATLAB toolbox that offers both graphical user interface and script-based access to visualize process grazing-incidence X-ray scattering data from nanostructures on surfaces in thin films. It provides routine surface reduction methods such as geometric correction, one-dimensional intensity linecut, two-dimensional reshaping etc. Three-dimensional indexing also implemented determine the space group lattice parameters of buried organized nanoscopic structures supported
Abstract Due to their unique properties, polymers – typically thermal insulators can open up opportunities for advanced management when they are transformed into conductors. Recent studies have shown achieve high conductivity, but the transport mechanisms yet be elucidated. Here we report polyethylene films with a conductivity of 62 Wm −1 K , over two orders-of-magnitude greater than that typical (~0.1 ) and exceeding many metals ceramics. Structural modeling reveal film consists nanofibers...
Molecular engineering of intra- and interchain interactions transforms polymers into good heat conductors.
The commercialization of nonfullerene organic solar cells (OSCs) critically relies on the response under typical operating conditions (for instance, temperature and humidity) ability scale-up. Despite rapid increase in power conversion efficiency (PCE) spin-coated devices fabricated a protective atmosphere, efficiencies printed OSC by blade coating are still lower than 6%. This slow progress significantly limits practical printing high-performance OSCs. Here, new relatively stable...
The technique of X-ray Photon Correlation Spectroscopy (XPCS) is reviewed as a method for studying the relatively slow dynamics materials on time scales ranging from microseconds to thousands seconds and length microns down nanometers. We focus application this study dynamical fluctuations surfaces, interfaces thin films. first discuss instrumental issues such effects partial coherence (or alternatively finite resolution) optimization signal-to-noise ratios in experiments. then review what...
Polyelectrolyte complexes are a fascinating class of soft materials that can span the full spectrum mechanical properties from low-viscosity fluids to glassy solids. This be accessed by modulating extent electrostatic association in these complexes. However, realize potential polyelectrolyte as functional materials, their molecular level details need clearly correlated with response. The present work demonstrates making simple amendments chain architecture, it is possible affect salt...
The integration of metal-organic frameworks (MOFs) with semiconductors has attracted mounting attention for photocatalytic applications. However, more efforts are needed to unravel the interface structure in MOF/semiconductor composites and its role charge transfer. Herein, a MIL-100(Fe)/TiO2 composite was synthesized as prototypical photocatalyst studied systematically explore transfer pathways during processes. fabricated by growing MIL-100(Fe) crystals on TiO2 using surface-coated FeOOH...
As an increasingly important structural-characterization technique, grazing-incidence X-ray scattering (GIXS) has found wide applications for in situ and real-time studies of nanostructures nanocomposites at surfaces interfaces.
