CCDC - The Cambridge Crystallographic Data Centre’s Post

💡Explore the packing environments and conformation of your polymorphs. This blog provides a guide on how to use two of the functionalities available in Mercury, 🔷Crystal Packing Similarity and 🔷Structure Overlay, to help you find differences and similarities in polymorphic structures. 🔗https://lnkd.in/eB4M6fU6 #Polymorphs #Crystallography

#Raman_spectroscopy can be used to investigate the defect properties and degree of #graphitization exhibited by #carbon_materials based on bands in the range of 1200-1700cm−1 .As shown by the #Raman_spectra of the AnCTFs in two strong peaks are located at 1350 and 1602 cm−1 which are characteristic of the D and G bands, respectively, thus confirming the presence of graphitic carbonized structures and carbona- ceous materials formed by the CTFs.The D and G bands represent sp2 and sp3 hybridization, respectively, corresponding to first-and second-order #Raman_scattering. ID/IG ratios of 1.01, 1.04, 1.11, and 1.03 were reported for An-CTF-10-400,An-CTF-20-400,An-CTF-10-500,and An-CTF-20-500, respectively . These values suggest that An- CTF-10-400, An-CTF-20-400, and An-CTF-20-500 have higher degrees of graphitization, thereby providing an indirect indication that these materials contained fewer defect sand more condensed aromatic structures than An-CTF-10-500. https://lnkd.in/eedAz_9k 🧪🥽📈 #COFs #porosity #composites #aqueous_stability #Covalent_Organic_Frameworks #porosity #drug_delivery #catalyst #water_trestment #Gas_storage #linker #FTIR #bond_formation #building_blocks #Raman_spectroscopy #graphitization

But when constructing on a soil base its mechanical properties have to be very well understood. And the structure of natural soil and "𝘳𝘦𝘮𝘰𝘭𝘥𝘦𝘥" (worked, manipulated if you like) soil can be very different which can drastically alter its mechanical and water holding properties. This paper https://lnkd.in/ePQyDhpi reports the analysis of 𝘱𝘰𝘳𝘦 𝘤𝘩𝘢𝘳𝘢𝘤𝘵𝘦𝘳𝘪𝘴𝘵𝘪𝘤𝘴 of natural structured clay applying the combination of scanning electron microscopy (SEM) and 𝗺𝗲𝗿𝗰𝘂𝗿𝘆 𝗶𝗻𝘁𝗿𝘂𝘀𝗶𝗼𝗻 𝗽𝗼𝗿𝗼𝘀𝗶𝗺𝗲𝘁𝗿𝘆 (MIP). In this particular case remolded clays had large pore openings (approximately 2 to 200 μm) which were effectively absent in the naturally compacted samples. SEM confirmed particle rearrangement. MIP was done using PoreMaster 33 porosimeter https://lnkd.in/d297YB84 . Porous Material Characterization #soil #soilmechanics #porosity Image: NOT from cited paper, just for illustration.

After the succesfull installation of the laser diffraction particle sizer of FRITSCH Milling and Sizing a few years ago, Benelux Scientific was very thrilled to install the "dynamic image analyser" as a complementary addition of the particle characterization offering of Qmineral Analysis & Consulting. This dynamic image analyser brings additional characterization of powders, where the shape of particles is the discriminating factor. If anyone is in search of contract testing in particle analysis, please contact Qmineral Analysis & Consulting. They can offer sieving, laser diffraction and shape analysis with their FRITSCH Milling and Sizing product portfolio besides many other techniques. #particle #particleshape #dynamicimageanalysis #laserdiffraction #particlecharacterization #fritsch #beneluxscientific

Our new video introduces you to a crystallographic symmetry operation called the glide reflection. Glide reflections and glide planes are first defined, before two types of crystallographic glide reflections - axial glides and diagonal glides - are explored. 🔗https://lnkd.in/e4GxkBmh #Crystallography #STEM
