A bulk single crystal sample of cadmium telluride (CdTe) was irradiated with a ~3 mJ/cm infrared femtosecond laser and analyzed with time-resolved X-ray diffraction (XRD) performed on an in-air tabletop designed for an extremely short pulsed X-ray source. The integrated intensity of Kα XRD lines from the CdTe (111) plane was decreased by 4%–5% in the time scale of ~200 ps. The changes in integr...
Density, chemical, structural and vibrational studies of GexSb65Se35-x system with 0 ≤ x ≤ 20 produce by melt-quench technique were carried out using Archimedes method, Energy Dispersive Spectroscopy (EDS), X-ray diffraction (XRD) and Raman spectroscopy. All specimens are polycrystalline in nature as confirmed by XRD pattern. The compositional dependence of the XRD and Raman spectra suggests th...
هدف: هدف از پژوهش حاضر، شناسایی مؤلفههای آزردگیهای روانی انتقالیافته والدین به فرزندان، مبتنی بر مرور زندگی بود. روش: حاضر لحاظ روششناسی نوع کیفی و روش نظریه داده بنیاد و طریق نمونهگیری هدفمند نظری صورت گرفته است. جامعة موردپژوهش بین (پدر یا مادر) 35 تا 50 سال دارای فرزند نوجوان (دختر پسر در بازة سنی 13 18 سال) شهر تهران انتخاب شدند که بهصورت داوطلبانه مصاحبه حضور پیدا کردند. با استفاده ...
biological systems provide many examples of specifically tailored, nanostructured molecules with highly optimized properties and characteristics. these biomaterials are composite materials and consist of an inorganic component and a special organic matrix. crystalline bacterial cell surface layers (s-layers( are the outermost cell envelope component of many eubacteria and archaea and are compos...
به منظور بررسی تأثیر ترکیب کانی شناسی بر دوام و مقاومت سنگ ها، چهار نمونه از سنگ های هورنفلسی موجود در مناطق جنوبی و غربی شهر همدان واقع در غرب ایران انتخاب شدند. این نمونه ها در آزمایشگاه، تحت آزمایش های تعیین ویژگی های کانی شناسی، فیزیکی و مکانیکی قرار گرفتند. هم چنین نمونه های مذکور به تعداد 15 چرخه در محلول های اسید سولفوریک دارای ph مختلف، تحت انجام آزمایش دوام-وارفتگی و آزمایش xrd قرار گر...
Molecular beam epitaxy grown InAs/GaSb superlattices, containing InSb-like interfacial layers, were analyzed by a combination of x-ray diffraction XRD and structural refinement. The superlattice refinement from x rays SUPREX method determines with high accuracy the average thicknesses and d spacings of the individual InAs and GaSb layers in addition to standard structural parameters usually obt...
This section contains details regarding the preparation of catalyst and membranes and further details on the experimental setup (including two photographs of the XRD-CT experimental setup), a comment relating to an artefact present within this XRD-CT, normalised summed intensity changes (as a companion to Figure 2), XRD-CT data focusing on the BCFZ membrane, a diffraction pattern to illustrate ...
Pure bisthiourea cadmium bromide (BTCB) and 1 mole % L-alanine mixed bisthiourea cadmium bromide (LABTCB) single crystals have been grown by slow evaporation method. The grown crystals have been characterized by single crystal XRD analysis, powder XRD analysis, FTIR analysis, UV-Vis-NIR analysis and SHG studies. XRD analysis confirms the crystalline nature of the materials. The addition of L-al...
Chitosan–silver (CS–Ag) nanocomposite materials were synthesized by a simple chemical method. The synthesized CS–Ag nanocomposite contains 20 wt% silver. Silver nanoparticles were synthesized by chemical reduction method as well. The CS–Ag nanocomposite was characterized using Field emission scanning electronic microscope (FESEM), X-ray diffraction (XRD) and Fourier transform infrared spectrosc...
