TaC and HfC are thought to have the highest melting point (~4000°C) among all refractory materials. The binary solid solution of TaC and HfC (Ta4HfC5) is also considered as the most refractory material with the melting point over 4000 °C and valuable physical and mechanical properties. The main goal of this work is to fabricate TaC/HfCbased composites which consolidated by means of spark plasma...

Background The X-linked cyclin-dependent kinase like 5 (CDKL5/STK9) gene has been shown to be responsible for a severe encephalopathy condition characterized by early onset of epilepsy and severe developmental delay. CDKL5 mutations have been shown to be more frequent among female patients. Results Here we report a 6- month male patient, second child of a healthy non consanguineous in the Irani...

Refractory castables are utilized in hazardous environments and thus their reliability should be accurately evaluated to avoid incidents. This work aims measure the fracture energy of a high-alumina refractory with mullite-zirconia aggregates at 600 °C. Wedge Splitting Tests were performed on 5 samples different sintering temperatures. Images acquired analyzed via Digital Image Correlation (DIC...

Abstract Production and characterization of geopolymers prepared by mixing metakaolin, end-of-life dolomite refractories, sodium silicate solution, hydroxide solution have been performed. The as-received refractory was crumbled in order to obtain products having, respectively, 250 ?m, 1 mm, 2.5 mm maximum particles size. Each batch powder added different proportions a blank geopolymeric matrix....

NHL is the most common hematologic cancer in adults. Rituximab is the FDA approved treatment of relapsed or refractory low grade B-cell Non-Hodgkin Lymphoma (NHL). But patients eventually become resistant to rituximab. Since lymphocytes and lymphoma cells are highly radiosensitive, low grade NHL that has relapsed or refractory to standard therapy is treated by RIT in which a beta-emitting radio...

It has been the aim of this project to produce refractory calcium aluminate cement (CAC) with 70% alumina in the laboratory. Pure calcined alumina and lime were mixed and fired at different temperatures and times in a rotary kiln. When the clinker was formed, it removed out of the furnace and cooled rapidly. The presence of optimized amounts of monocalcium aluminate (CA) and Dicalcium aluminate...

Initial stages of the refractory degradation process by molten Al-5Mg alloy were investigated analyzing structures caused an interaction with metal during heat cycles. The aggregate, found to be poly-crystalline, consisting cristobalite (SiO2) and mullite (Al6Si2O13), was deteriorated ahead surrounding matrix. Metal permeated into refractory, forming a thin layer along crucible surface below li...
