Processing of foams from bulk metallic glass (BMG) alloys, using melt infiltration techniques, is reported for the first time. Foaming methods based on infiltration of two types of pattern materials are described: investment of a continuous refractory yielding very low relative density structures (5% dense relative to the BMG), and investment of a discontinuous refractory pellet bed yielding hi...

Abstract Refractory ‘stuffed’ pyrochlores such as Gd 2 TiO 5 are of interest for nuclear applications, including matrices actinide disposition and neutron absorbers in control rods. Here, we report the results a preliminary comparative investigation synthesis by molten salt conventional solid-state synthesis. We show that proceeds from pyrochlore phase Ti O 7 which is first formed kinetic produ...

Though efficient acid suppression with proton pump inhibitors (PPIs) remains the mainstay of treatment of gastroesophageal reflux disease (GERD), some of the patients showed refractory response to PPIs, necessitating further intervention. After increasing dose of PPIs and other kinds of pharmacological intervention adopting prokinetics or others, variable endoscopic treatments are introduced fo...

EFRACTORY anemia was omie of the first pathologic effects noted as a result of exposure to radioactive agents. Since the original description, published over forty-five years ago, a number of reports have appeared in the literature describing the occurrence of refractory anemia as a late effect of repeated exposures to x-rays or various radioactive materials.’ ‘ 2 , 3 The susceptibility of the ...

Increased operating temperatures and higher efficiency in gas turbines and jet engines can reduce CO2 emission, thus contributing to the prevention of global warming. To achieve this goal, it is essential to improve the properties of high temperature materials. Various Ni-base superalloys are used for high-temperature components, e.g., combustors and high-pressure turbine blades and vanes, that...

Comet dust is primitive and shows significant diversity. Our knowledge of the properties of primitive cometary particles has expanded significantly through microscale investigations of cosmic dust samples (anhydrous interplanetary dust particles (IDPs), chondritic porous (CP) IDPs and UltraCarbonaceous Antarctic micrometeorites, Stardust and Rosetta), as well as through remote sensing (Spitzer ...
