Hyperthermophiles are a group of microorganisms that have their optimum growth temperature above 80 degrees C. More than 60 species of the hyperthermophiles have been isolated from marine and continental volcanic environments. Most hyperthermophiles belong to Archaea, the third domain of life, and are considered to be…

Ferrimagnetic glass-ceramics are useful as thermoseeds for hyperthermal treatment of malignant tumors, especially those located in deep parts of the body, since hysteresis loss heating occurs locally at the cancer site when they are implanted around the tumor and subjected to an alternating magnetic field. In the pres…

Iron-chromium ferritic alloy is a candidate for the interconnect of solid oxide fuel cells (SOFCs). Gastightness is one of the most important properties of the interconnect in a planar-type SOFC. Hydrogen permeation in an iron-chromium alloy was measured in an atmosphere simulating an SOFC at 1073 K. Hydrogen permeabi…
