摘要:... Ruby rats carrying Rab38 and other gene mutations exhibit oculocutaneous albinism, bleeding diathesis, and hence, are a rat model of human Hermansky-Pudlak syndrome (HPS). We previously showed that Long Evans Cinnamon (LEC) rats, one strain of the Ruby rats, develo...

摘要:Abstract(#br)The Yuanjiang marble-hosted ruby deposit in the middle Ailao Shan-Red River (ASRR) shear zone, is the only economic ruby deposit in China. This deposit is hosted in Paleoproterozoic sillimanite gneisses and the ores are found in metamorphosed platform carbonates. Rubies...

摘要:Abstract(#br)We have studied the Cr-K-edge XANES and EXAFS in natural Indian rubies from two sources and a synthetic ruby at ESRF. Weight % of various constituents in them is determined using EDAX measurements. Taking the results from the three techniques together we are able to ...

摘要:Abstract(#br)Rubies and sapphires are of both scientific and commercial interest. These gemstones are corundum colored by transition elements within the alumina crystal lattice: Cr 3+ yields red in ruby and Fe 2+ , Fe 3+ , and Ti 4+ ionic interactions color sapphires. A minor ion...

摘要:... The present report is on surface hardening of oil-hardened nonshrinking (OHNS) steel using Ruby laser in normal mode. It is found that surface hardening increases thrice the size of base material and the microstructure of the laser-heated zone changes from pearlite phase to m...

摘要:Abstract(#br)Two sharp line-like bands called N and R lines on the red side, a close doublet ( B lines) on the violet side and two broad bands are observed for natural ruby. At liquid air temperature the splitting of R line was found and also three sharp-bands called R, R′ and...

摘要:Ruby (Cr:Al2O3) single crystals were grown by the Czochralski technique in an argon atmosphere. The critical crystal diameter dc = 1.0 cm and the critical rate of rotation wc = 20 rpm were calculated by equations of the hydrodynamics of the melt. The rate of crystal growthwas exp...

摘要:... A ruby laser (X=694.3 nm) was used to modify the material. The structural changes were examined by scanning electron microscopy and X-ray diffraction. It was established that the radiation of this laser induces structural changes leading to a better arrangement of the turbost...

摘要:In the work, features of the layer-by-layer selective laser synthesis (SLS) of ruby from an Al2O3-Cr2O3 mixture are considered depending on the irradiation power, the laser beam traverse speed, the height and amount of the backfill of powder layers. It has been established that, ...
