We have designed a nano-sheet-like porous organic polymer (POP) constructed via schematic hydrothermal process and characterized it using PXRD, N 2 adsorption–desorption studies, UV-vis, XPS microscopic analyses (TEM FESEM).

Inorganic-organic hybrid material based on Eu and calix[4]arene bearing four carboxylic acid groups has been synthesized via hydro(solvo)thermal method assisted by microwave irradiation. The obtained sample was characterized by FT-IR, PXRD, SEM and photoluminescence. The results showed the formation of coordination polymer with low symmetry around Eu ion. The monoexponential luminescence decay ...

A new organic-lanthanide framework [TbL1.5(H2O)2]·H2O (1) [H2L = 5-(3'-carboxylphenyl)nicotinic acid] was synthesized. Its structure was determined by single crystal X-ray diffraction. The complex was characterized by PXRD, FT-IR, fluorescence as well as TGA, and features a 3D framework with a 1D channel and exhibits exceptionally high thermal stability up to 440 °C in air. Furthermore, it disp...

A series of metallosalen-based metal-organic frameworks (MOFs) have been prepared by the post-synthesis modification of Mn(III)SO-MOF, a Mn(3+)(salen)-based MOF. Treatment of Mn(III)SO-MOF with H(2)O(2) effects the removal of the Mn(3+) ions from the salen struts, which can then be remetalated with a variety of metal precursors to form isostructural MSO-MOF materials. The presence of the new me...

A 1-D helical tubular cadmium coordination polymer, [Cd(H2Me4bpz)(H2bidc)2]n (1, H2Me4bpz = 3,3',5,5'-tetramethyl-4,4'-bipyrazole; H3bidc = benzimidazole-5,6-dicarboxylic acid) was hydrothermally synthesized and characterized by means of elemental analyses, PXRD, IR, 2D IR correlation spectra, solid UV, TG analysis, luminescence spectroscopy and single crystal X-ray diffraction. The crystal str...

The zinc oxide-silver oxide nanocomposite (ZnO.Ag2O3 particles) was prepared by using an aqueous plant extract of Haplophyllum obtusifolium for the first time. Powder X-ray diffraction (PXRD), Fourier transforms spectroscopy (FTIR), field emission microscopy (FESEM), energy dispersive analysis (EDX), and transmission electron (TEM) were applied to analyze structure, functional groups, morpholog...

<p class="Abstract">To assess the provenance of limestones used in construction and restoration Batalha Monastery central Portugal, stone samples collected from monument five limestone quarries region surrounding building were investigated by energy-dispersive X-ray fluorescence spectroscopy (ED-XRF), powder diffractometry (PXRD) thermogravimetric analysis (TGA). Ca-Sr binary diagrams ED-...

Assembly of copper(I) halide with a new tripodal ligand, benzene-1,3,5-triyl triisonicotinate (BTTP4), afforded two porous metal-organic frameworks, [Cu(2)I(2)(BTTP4)]⊃2CH(3)CN (1·2CH(3)CN) and [CuBr(BTTP4)]⊃(CH(3)CN·CHCl(3)·H(2)O) (2·solvents), which have been characterized by IR spectroscopy, thermogravimetry (TG), single-crystal, and powder X-ray diffraction (PXRD) methods. Compound 1 is a p...

In this work, size-controlled synthesis of nickel ferrite nanoparticles was achieved by the calcination a bimetallic (Fe/Ni) metal-organic framework (MOF). The MOF (Fe2Ni-MIL-88B) itself prepared two-step route. first step involved secondary building unit (SBU) reacting stoichiometric amounts Ni and Fe precursors with acetic acid. A ligand substitution reaction (terephthalate replaces acetate) ...

Laboratory X-ray powder microdiffraction (micro-pXRD) is a very effective non-destructive method for direct phase analysis of samples smaller than 1 mm containing crystal constituents with no need of their pre-treatment. It is suitable for identification of pigments in fragments of colour layers of artworks, or their cross-sections, as well as for examination of secondary degradation products. ...
