Single Crystals of Perylene Diimide‐Based Two‐Dimensional Covalent Organic Frameworks
Advanced Materials, EarlyView.Synthesizing extended crystals of two‐dimensional covalent organic frameworks (2D COFs) has remained a major challenge. Here, we report a high‐temperature double‐modulator strategy that provides access to new perylene diimide (PDI)‐based COFs with crystal sizes of up to 50 µm.

Ciencia del Suelo, 2007 The mineralogical quantification of soils species is mainly obtained by analysis of X-ray diffraction (XRD) patterns. The classic method, for these analyses, is limited to semi quantitative determinations due to the overlapping of different specie's ...

Quantitative phase analysis of anhydrous clinker Portland using Rietveld method
Modern cements are complex materials with well-defined compositions that reach to high and consistent results. Automated techniques such as Rietveld analysis lead to provide an understanding of the composition and polymorphism of cement phases that could

Mechanical Stress Evolution in Polycrystalline Ge Thin Films Under MeV Ion Irradiation
Advanced Materials Interfaces, EarlyView.Irradiation of polycrystalline Ge thin films with 1.8 MeV Au ions alters residual stress through defect generation and lattice expansion. Increasing fluence drives progressive lattice disorder and eventual amorphization. Polycrystalline Ge resists amorphization longer than crystalline Ge, as grain boundaries facilitate defect diffusion, significantly ...

How Crystalline is My Cellulose Specimen? Probing the Limits of X-ray Diffraction
BioResources, 2022 Cellulose serves as a skeleton for many of the useful products upon which we rely on each day. When we want to learn about a skeleton, it makes sense to think about X-ray methods.

Advanced Materials Interfaces, EarlyView.A Si and SnS2 based dual‐alloy anode material for metal‐ion battery applications with improved structural, interfacial and electrochemical properties is synthesized via a single‐step solid‐state pyrolysis process. During the pyrolysis step, SnS2 and Si are embedded in a porous, carbonized PAN‐based matrix, which is electronically and ionically ...

Advanced Materials Technologies, EarlyView.Milled polycrystalline NMC811 cathode (MPC NMC) with smaller secondary particle and higher surface area had 1) greater cathode tortuosity, 2) reduced surface Ni on the cycled MPC cathodes consistent with surface reconstruction, and 3) increased Ni deposition from cathode‐anode crosstalk, manifesting in lower functional capacity and higher impedance ...
