In the present study, we collected and investigated spinels from Man Sin deposit in Myanmar using standard gemological testing, microscopic observation, EDXRF, Raman spectrometry. The color observation was performed under various lighting conditions to show differences. A very high Cr/Fe ratio is linked with exceptionally strong red fluorescence. Microscopic spectroscopy identified mineral incl...

In this work, the photostimulated processes of O2 and NO2 molecules with surface ZnO under UV radiation were studied by in situ mass spectrometry temperature range 30–100 ?C. Nanocrystalline needle-like was synthesized decomposition basic zinc carbonate at 300 ?C, concentration oxygen vacancies it controlled reductive post-annealing an inert gas 170 The materials characterized XRD, SEM, low-tem...

ft-sers (fourier transform surface enhanced raman scattering) of adriamycin and its complex with dna is reported. it is shown that in agreement with previous raman studies the interaction of adriamycin  with dna takes place through an intercalation mechanism. the presence of a new band at 731 cm-1 suggests that ring d of adriamycin is not involved in the intercalation process.

diamond like carbon (dlc) film was grown by hot filament chemical vapor deposition (hfcvd)technique. in the present work, we investigated the quality of the dlc films groew on the substratesthat were coated with various metal nanocatalysts (au and ni). a combination of ch4/ar/h2 rendersthe growth of carbon nanostructures technique (diamond like carbon). the utilized samples werecharacterized by...

The efficient integration of transition metal dichalcogenides (TMDs) into the current electronic device technology requires mastering techniques effective tuning their optoelectronic properties. Specifically, controllable doping is essential. For conventional bulk semiconductors, ion implantation most developed method offering stable and tunable doping. In this work, we demonstrate n-type in Mo...

The heritage left by the Arab world in history of science is directly related to innovations both manufacturing paper and production ink. Four Moroccan manuscripts dating eighteenth century, conserved at royal library Rabat, have been analyzed X-ray diffraction (XRD), energy-dispersive fluorescence spectrometry (EDXRF), scanning electron microscopy coupled energy dispersive spectroscopy (SEM–ED...

Recently, aquamarine was discovered in the Cuonadong Be-W-Sn Polymetallic Deposit, Longzi County, Tibet. is being extracted and expected to be available over next decade. This study provides a full set of data through standard gemmological properties, including scenes, color characteristics advanced spectroscopic chemical analyses, micro ultraviolet–visible–near-infrared (UV–Vis–NIR), Raman las...

Two-dimensional (2D) metal nitrides are new emerging materials with potential applications in electronics, energy storage, or conversion efficiency. In this paper, we report the synthesis of molybdenum nitride by nitriding disulfide (MoS2) via a 700 °C ammonia (NH3) reactive heat treatment. A well-controlled uniform MoS2 thin film was prepared atomic layer deposition (ALD). The progressive reac...

Molecular magnets attached to carbon nanotubes (CNT) are being studied as potential candidates for developing spintronic and quantum technologies. However, the functionalization routes used develop these hybrid systems can drastically affect their respective physiochemical properties. Due complexity of this systems, little work has been directed at establishing correlation between degree magnet...

Introduction: To date, gold nanoparticles (GNPs) have been demonstrated to have great potential as contrast agent for CT imaging and therapeutics. This study was designed to evaluate any effect on X-ray attenuation that might result from using GNPs with a variety of size, surface chemistries and shapes.   Materials and Methods: Spherical GNPs and gold nanorod...
