In this critical review, we aim at providing a holistic representation of crystal-like structure formation mediated by hydrodynamic interactions in microfluidic devices.
The compound of (Htmb)2[Ni(pydc)2)].H2O (1) (In that tmb and pydc are 3,3¢,5,5¢-tetramethyl benzidine and pyridine -2,6- dicarboxylic acid, respectively) was synthesized via the proton transfer method and the structure was determined by single crystal X-ray diffraction. This compound crystalized in monoclinic crystal system and C2/c space group. In the asymmetry unit of compound 1, there are h...
Reitveld full profile refinement analysis has been done on Synchrotron diffraction data from a powder sample of YBCOx at RT and 500°C. Anisotropic peak broadening for (h00) and (hh0) lines has been observed by Williamson-Hall (W-H) analysis and that is in agreement with formation of twin's microstructures along (110) crystal planes in the sample. In addition, size and strain of the crystallites...
conclusions: these data demonstrated that the attachment of bacteria to hydrophilic acrylic iols was more than hydrophobic pmma ones independent of the brand. according to these results the bacterial strain might have more hydrophilic properties. augmenting the biomass of biofilm by passing of time demonstrated the key role of time in biofilm formation on the iol surfaces. the differences betwe...
Calcium pyrophosphate dihydrate (CPPD) crystals are common components of osteoarthritic joints and correlate with a poor prognosis. Transglutaminase (Tgase) enzymes have been implicated in pathologic mineralization in cartilage; yet, definitive studies linking Tgase activity to CPPD crystal formation in osteoarthritic articular cartilage are lacking. We measured in-vivo Tgase activity in osteoa...
Introduction Atomic Structures and Properties Electronic configurations Radii of atoms and ions Ionisation enthalpies Oxidation states Compound formation in maximum oxidation states Stability of compounds in aqueous solution Magnetic properties Coloured ion formation Alloy formation Interstitial compound formation Coordination Compounds Types of ligands Homleptic and heteroleptic complexes Coor...
Mixed-ligand Cu(II) complex was prepared by reaction of salicylaldehyde S-benzylisothiosemicarbazone hydrogenchloride ligand (H2L), Cu(ACo)2.H2O and 1,10-phenanthroline with general formulas [Cu(Phen)2Cl].H2L,Cl,H2O. Its structure was fully characterized by elemental analysis and IR method and single crystal diffraction was also used to better understanding of the molecular structure of the Cu(...
It is a challenge to develop methodologies involving multiple transformations for preparing new materials that cannot be obtained via direct synthesis. Herein, we report an anion exchange process accompanying cation reduction and dimerisation via a single-crystal-to-single-crystal transformation. First, a direct reaction of the flexible tripyridyl dithioether ligand L with CuI afforded a mixtur...
