A review of the recent literature is presented which assesses the development of robust microporous porphyrin framework solids and their potential to perform selective sorption or heterogeneous shapeor size-selective catalysis. The review focuses only on those porphyrin solids whose porosity is robust, i.e. whose framework remains after the removal of solvates, as determined by thermal gravimet...

Nanocrystalline ceria has been synthesized by a non-hydrolytic method using organic solvent and precipitant. The effect of the source compound on final nanocrystalline powder was investigated. The cerium nitrate hexahydrate subjected to different vacuum/thermal treatments to get cerium source compound having different extent of water of crystallization. The nanoceria, synthesized from these com...

Single crystal dixanthinium tetrachlorozincate has been grown from dilute chloridric acid. Polarized Raman spectrum of the single crystalline sample, FT-Raman and FT-IR spectra of the polycrystalline samples have been examined and the bands assigned to the appropriate modes predicted by a factor group analysis for the space group Pmn21. The crystal structure has been confirmed by powder XRD mea...

Magnesium nitride (Mg3N2) has gained extensive attention due to its catalytic and optoelectronic properties. The present investigation was aimed to evaluate the effect of biofield energy treatment on physical and thermal properties of Mg3N2 powder. The Mg3N2 powder was divided into two parts i.e. control and treated. The control part was remained as untreated and the treated part was subjected ...

Powder X-ray diffraction (XRD) and solid-state NMR spectroscopy are complementary techniques for investigating the structural properties of solids, there considerable opportunities advantages to applying these synergistically together in determining crystalline solids. This article provides an overview potential exploit information derived from data assist enhance process crystal structure dete...

X-ray powder diffraction (XRD) is an essential component of research into use of organometallic precursors as a route to low temperature (<500 “C) synthesis of bulk compound semiconductors. This paper illustrates the use of XRD to study solid solution behavior in the systems SnS-SnSe and PbS-CdS. XRD characterization demonstrated that phase pure intermediate members of the Sn(S,Se) solid soluti...

Introduction: Coring tools have been used effectively on the Moon, but to date no such tools have been used on any other extraterrestrial surface. The lunar experience includes both manual (Apollo) and robotic (Luna) systems. These coring systems were concerned primarily with acquiring samples from depth for return to Earth or for the creation of instrument emplacement holes (e.g., heat probes)...
