New methods for structure determination and speciation by NMR crystallography

Martins Balodis

NMR crystallography has been around for half a century, but with the advent of NMR crystal structure determination protocols in the last decade it has shown perspectives that were not seen before. Amalgamation of NMR and crystal structure determination has ...

Concrete cancer : characterization of Alkali Silica Reaction early stage products by electron microscopy

Solène Anne-Lise Albinski

Concrete deterioration is a natural process, which has to be carefully monitored over a the service life of a structure. The Alkali-Silica Reaction (ASR) is a slow-process degradation, which devel-ops over decades and is therefore difficult to predict. Sin ...

Cubic, hexagonal and tetragonal FeGex phases (x = 1, 1.5, 2): Raman spectroscopy and magnetic properties

Anna Fontcuberta i Morral, Dirk Grundler, Santhanu Panikar Ramanandan, Nicolas Tappy, Anna Kúkol'ová

There is currently an emerging drive towards computational materials design and fabrication of predicted novel materials. One of the keys to developing appropriate fabrication methods is determination of the composition and phase. Here we explore the FeGe ...

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, ...

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 ...

The Role of Alkyl Chain Length and Halide Counter Ion in Layered Dion−Jacobson Perovskites with Aromatic Spacers

Jacques-Edouard Moser, Jovana Milic, Joachim Maier, Michael Allan Hope, George Cameron Fish, Algirdas Ducinskas, Loï Charles Carbone, Davide Moia

Layered hybrid perovskites based on Dion−Jacobson phases are of interest to various optoelectronic applications. However, the understanding of their structure−property relationships remains limited. Here, we present a systematic study of Dion−Jacobson pero ...

Chalcogenide glasses for innovation in applied science: fundamental issues and new insights

Assil Bouzid, Carlo Massobrio

We provide an overview of what has been accomplished by our team, since 1998, in the area of first-principles molecular dynamics (FPMD) modeling of glassy chalcogenides, a prototypical family of network-forming disordered materials. After a broad introduct ...

Strain glass transition of cobalt phase in a cemented carbide

Daniele Mari, Samy Adjam

Cemented carbides are hard materials used for the fabrication of cutting tools. They consist of hard micron or sub-micron carbide grains held together in a matrix of a tough metallic binder such as cobalt. The understanding and control of cobalt characteri ...

Characterization, mechanical properties and dimensional accuracy of a Zr-based bulk metallic glass manufactured via laser powder-bed fusion

Roland Logé, Steven Van Petegem, Jamasp Jhabvala, Antonia Neels, Efthymios Polatidis, Annapaola Parrilli, Güven Kurtuldu, Navid Sohrabi

Bulk metallic glasses (BMGs) are high-strength, highly elastic materials due to their disordered atomic structure. Because BMGs require sufficiently high cooling rates to bypass crystallization, laser-based additive manufacturing (AM) methods have recently ...
