Yttrium silicate coating[5, 6] is a promising candidate for oxidation resistant coating for its low oxygen diffusion coefficient and similar thermal expansion coefficient with silicon carbide. Webster et. al.[7] had prepared yttrium silicate coating on C/SiC using Y2O3/SiO2 slips by slip casting and sintering. The selected sintering parameters were 3 h at 1600 °C in flowing argon. The coating c...

The crystallization behavior of a glass with the composition 54.7 SiO2·10.9 Al2O3·15.0 MgO·3.4 ZrO2·16.0 Y2O3 is studied using X-ray diffraction (XRD), scanning electron microscopy (SEM) including electron backscatter diffraction (EBSD) and (scanning) transmission electron microscopy [(S)TEM] including energy-dispersive X-ray spectrometry (EDXS). This glass shows the sole surface crystallizatio...

Polycrystalline yttrium aluminum garnet (YAG) fibers were prepared from commercially available colloidal sols of Y,O, and AlOOH and water-soluble polymers. The fibers were dry spun and all processing was performed in air. Transformation to YAG was complete by =1300"C, and the fibers were mostly dense by 1600°C with a final fired diameter of 120 pm. A bend test was used to characterize mechanica...

New technologies based on micro-technology, so called MEMS (Micro ElectroMechanical Systems), have been enabling many new products over the last ten years such as inkjet printers, displays or pressure sensors. Focusing on measurement of motion, MEMS inertial sensors such as accelerometers and gyroscopes, open new application fi elds for three big branches: Testing of MEMS based Inertial Sensors...

Liver metastases from colorectal cancer (CRC) result in substantial morbidity and mortality. The primary treatment is systemic chemotherapy, and in selected patients, surgical resection; however, for patients who are not surgical candidates and/or fail systemic chemotherapy, liver-directed therapies are increasingly being utilized. Yttrium-90 (Y-90) microsphere therapy, also known as selective ...

Radioimmunotherapy is a new cancer therapy that combines the cytotoxicity of radiation with the tumor-specific targeting of monoclonal antibodies. Yttrium 90 (Y-90) ibritumomab tiuxetan (Zevalin, IDEC Pharmaceuticals Corporation, San Diego, CA) is indicated for the treatment of patients with relapsed or refractory low-grade, follicular, or transformed B-cell non-Hodgkin's lymphoma (NHL), includ...

The picosecond lasers have shown to effectively treat tattoo pigments that are intractable to previous multiple Q-switched (QS) laser treatments. Therefore we hypothesized that a picosecond laser would show better efficacy with minimal adverse events in the treatment of melasma and post-inflammatory hyperpigmentation (PIH) that are difficult to treat with conventional QS lasers. Two patients wi...

We report a case of an epithelial inclusion cyst of the iris following cataract surgery that was successfully treated with en bloc excision, after an unsuccessful attempt with Neodymium-doped Yttrium Aluminium Garnet (Nd YAG) Laser. A 60-year-old man had undergone cataract surgery two years back. One year later, he developed a pigmented epithelial inclusion cyst of the iris which progressively ...

OBJECTIVE Although recent experience suggests that transmyocardial laser revascularisation (TMLR) relieves angina, its mechanism of action remains undefined. We examined its functional effects and analysed its morphological features in an animal model of acute ischaemia. METHODS A total of 15 pigs were randomised to ligation of left marginal arteries (infarction group, n = 5), to TMLR of the ...

A nonaqueous synthetic route for the preparation of a regular crystalline yttria mesostructure is presented. The reaction between yttrium alkoxides and benzyl alcohol results in the formation of a highly ordered lamellar nanocomposite consisting of yttria layers with a confined thickness of about 0.6 nm, separated from each other by organic layers of intercalated benzoate molecules. Doping with...
