This article presents the design and manufacture of an automated scale model a four-circle single-crystal X-ray diffractometer that can be used for scientific dissemination. The purpose this device is to reach out wider public students introduce them in entertaining way one laboratory apparatuses which they do not usually have access, talk about crystallography broadest sense, develop concepts ...

Deformation behaviour of rolled AZ31 sheets that were subjected to the accumulative roll bonding was investigated. Substantially refined microstructure of samples was achieved after the first and second pass through the rolling mill. Sheets texture was investigated using an X-ray diffractometer. Samples for tensile tests were cut either parallel or perpendicular to the rolling direction. Tensil...

The germanide Ce2Rh3Ge5 was synthesized from the elements in a bismuth flux, and the structure was refined from single-crystal X-ray diffractometer data: U2Co3Si5 type, Ibam, a = 1010.1(2), b = 1210.4(2), c = 599.1(1) pm, wR = 0.0596, 760 structure factors, 31 variables. The rhodium and germanium atoms build up a three-dimensional [Rh3Ge5] network (242 – 269 pm Rh–Ge; 300 pm Rh–Rh; 266 pm Ge–Ge...

Visible light accounts for about 43% of the solar spectrum, and developing highly efficient visible-light-driven photocatalyst is of special significance. In this work, highly efficient three-dimensional (3D) Cd1-xZnxS photocatalysts for hydrogen generation under the irradiation of visible light were synthesized via one-step solvothermal pathway. Scanning electron microscope, X-ray diffractomet...

Diamond thin films are grown on silicon substrates by only using methanol and argon mixtures in microwave plasma chemical vapor deposition (MPCVD) reactor. It is worth mentioning that the novel strategy makes the synthesis reaction works smoothly without hydrogen atmosphere, and the substrates temperature is only 500 °C. The evidence of surface morphology and thickness under different time is o...

The laboratory implementation of grazing incidence in-plane X-ray diffraction, using an unmodified commercial diffractometer, is described. Low resolution, high intensity measurements are illustrated in the study of the in-plane lattice parameters and texture of a thin polycrystalline ZnO film on glass, the in-plane order in Cd arachidate Langmuir-Blodgett films, and the depth dependence of lat...

One-dimensional cobalt nanostructures with large aspect ratio up to 450 have been prepared via a template-free hydrazine reduction route under external magnetic field assistance. The morphology and properties of cobalt nanostructures were characterized by scanning electron microscopy, X-ray diffractometer, and vibrating sample magnetometer. The roles of the reaction conditions such as temperatu...

Significant enhancement of the interlayer coupling strength has been achieved by depositing Co nanolayers on both sides of the Ru layer in a conventional CoCrPt/Ru/CoCrPt antiferromagnetic interlayer exchange coupling structure. The interlayer coupling increases nearly linearly from 0.13 to 0.8 erg/cm and then levels off with an increase in Co thickness. Substrate bias was found to be very harm...
