Crystallographic studies of low symmetry organic molecular crystalline solids were performed by using XRD diffraction method. The well defined peaks appeared in the XRD profile of solids was indexed by using sin2 ratio method to understand the planes producing these peaks. The hkl values and d-spacing of the planes obtained from XRD file of diffractometer machine are feed into the software prog...

OBJECTIVE We compared laser-induced breakdown spectroscopy (LIBS) with the traditionally used and recommended X-ray diffraction technique (XRD) for urinary stone analysis. MATERIAL AND METHODS In total, 65 patients with urinary calculi were enrolled in this prospective study. Stones were obtained after surgical or extracorporeal shockwave lithotripsy procedures. All stones were divided into t...

Pressure- and temperature-induced phase transitions have been studied for more than a century but very little is known about the non-equilibrium processes by which the atoms rearrange. Shock compression generates a nearly instantaneous propagating high-pressure/temperature condition while in situ X-ray diffraction (XRD) probes the time-dependent atomic arrangement. Here we present in situ pump-...

In this paper, we have reported convenient way to access CdTe nanorods by solvothermal decomposition using single source molecular precursor cadmium (II) bis-(isopropyl telluro) propane (SSMP) and quinoline as solvent at relatively low temperature (200oC).As synthesized nanomaterials are structurally characterized by XRD, SEM and UVVisible spectroscopy. SEM micrographs revealed formation of rod...

Micro-Raman spectroscopy has been used to follow the reaction of free lime (CaO) exposed for 24h to moist air at 80 °C under conditions of different relative humidities (10-80% RH). X-ray diffraction and SEM imaging were applied as complementary techniques. The conversion of lime to calcium hydroxide and its subsequent carbonation to various calcium carbonate polymorphs was found to strongly de...

Objectives: This study sought to assess the relation of mandibular cortical index (MCI) with age, gender and gonial angle size in an Iranian adult population using digital panoramic radiography. Methods: We evaluated 370 digital panoramic radiographs of patients and divided them into five 10-year age groups. Each radiograph was assigned to low (≤120°) or high (≥125°) angle grou...

We determine the weak mixing angle in the MS-scheme, sin θ̂W (μ), at energy scales μ relevant for present and future low energy electroweak measurements. We relate the renormalization group evolution of sin θ̂W (μ) to the corresponding evolution of α̂(μ) and include higher-order terms in αs and α that had not been treated in previous analyses. We also up-date the analysis of non-perturbative, hadr...

X-ray diffraction has been a standard technique for investigating structural properties of materials. However, most common applications in the organic materials community have been restricted to either chemical identification or qualitative strain analysis. Moreover, its use for polymeric thin films has been challenging because of the low structure factor of carbon and the thin film nature of t...

The price of single point diamond tools with a sharp tip is very high due to complex machining process and highly expensive machining equipments. Yet, the performance is not quite satisfactory. In this paper, we have presented a very simple and cost effective machining process for the sharpening and polishing of diamond stylus using low energy reactive ion beam machining (RIBM). In our method, ...
