Microwave assisted hydrothermal (MAH) method was used to synthesize crystalline bismuth ferrite (BiFeO3) nanoparticles (BFO) at temperature of 180?C with times ranging from 5 min 1 h. For comparison, BFO powders were also crystallized by the soft chemistry route in a conventional furnace 850?C for 4 X-ray diffraction (XRD) results verified formation perovskite crystallites while infrared data showed no traces carbonate. Field emission scanning microcopy (FE/SEM) revealed homogeneous size...
This manuscript reports the first example of up-conversion properties involving Yb3+ and Tb3+ ions in five isostructural Lanthanide-Organic Frameworks (LnOFs), herein designated as UCMarker-1 to UCMarker-5, respectively, their application optical probes for identification gunshot residues (GSRs) ammunition encryption procedure. The excitation 2F7/2 ↔ 2F5/2 transition (980 nm) at room temperature leads visible (UC) emission 5D4 → 7FJ. GSR lead-free primer are easily identified upon UV...
The crystal structure of propylthiouracil, a drug used in the treatment hyperthyroidism, was determined by means high-resolution synchrotron X-ray powder diffraction data. Rietveld method employed to refine structure. This crystallizes an orthorhombic (Pcab) space group, with unit cell parameters = 28.67338(23) Å, b 11.15287(6) c 10.66821(5) V 3411.59(4) Å3, Z 16, Z′ 2, M 170.23 g mol−1, ρcalc 1.3258(1) cm−3. goodness-of-fit and R-factors were, respectively: χ2 1.599, RBragg 1.57%, Rwp 8.85%...
The use of flubendazole (FBZ) in the treatment lymphatic filariasis and onchocerciasis (two high incidence neglected tropical diseases) has been hampered by its poor aqueous solubility. A material consisting binary flubendazole/maleic acid crystals (FBZ/MA), showing considerably improved solubility dissolution rate relative to alone, prepared this work through solvent assisted mechanical grinding. identification FBZ/MA as a crystalline compound with salt character (proton transfer from MA...
Solid dispersions (SDs) of ursolic acid (UA) were developed using polyvinylpyrrolidone K30 (PVP K30) in combination with non-ionic surfactants, such as D-α-tocopherol polyethylene glycol 1000 succinate (TPGS) or poloxamer 407 (P407) the aim enhancing solubility and vitro release UA. SDs investigated a 24 full factorial design, subsequently selected formulations characterized for water solubility, X-ray diffractometry (XRD), differential scanning calorimetry (DSC), particle diameter, electron...
This study evaluated microstructural and crystallographic phase changes after grinding (G) regeneration firing/anneling (R) of Y-TZP ceramics. Thirty five bars (LavaTM Ice Zirkon) were divided: pre-sintered, control (C), firing (R), dry (DG), grinding+regeneration (DGR), wet (WG) (WGR). Grinding was conducted using a diamond bur annealing at 1,000°C. The microstructure analyzed by SEM the crystalline phases X-ray diffraction (XRD). XRD showed that pre-sintered specimens contained tetragonal...
Conventional orthodontic treatment with the use of stainless steel may be detrimental to oral health by promoting demineralizing lesions appearance and increasing adhesion formation bacterial biofilm, inducing development cavities. An alternative that has been researched reduce side effects is coating materials antimicrobial nanoparticles. Nanometric- sized particles increase their surface area contact microbial membrane, consequently intensifying bacteriostatic bactericidal effect. In this...
Nickel polyphosphate coacervates have been prepared through the coacervation process of sodium and Ni<sup>2+</sup> chloride solutions.
Isotibolone is frequently found as an impurity in tibolone, a drug used for hormone reposition of post-menopause women, due to some inadequate tibolone synthesis or result degradation during storage. The presence isotibolone impurities should be detected and quantified active pharmaceutical ingredient products before its use the manufacturing medicaments. X-ray powder diffraction technique offers possibility quantifying amounts at different stages production storage, from chemical final...
BaxSr1−xTiO3 was prepared by the microwave-assisted hydrothermal method. The ceramic powder characterized X-ray diffraction, Raman, ultraviolet–visible and photoluminescence (PL) spectroscopies scanning electron microscopy (FE-SEM). results confirm that powders consist of perovskite-type cubic tetragonal crystalline structures. Raman data show bands characterizing a multi-phonon process, suggesting presence defects, due to partial Sr/Ba substitution, resulting in different distorted...
