Shahriar SheikhBahaei, Ph.D. Dr. SheikhBahaei’s interest in neuroscience stemmed from the usual combination of an aptitude for science and a medical problem (stuttering) that brought him into bioscience at a young age. Dr. SheikhBahaei received his bachelor’s degree from the University of California at Berkeley, where he worked with Dr. Bob Zucker on the regulation of neurotransmitter release and Dr. John Rubenstein (UC San Francisco) on development of GABAergic neurons in basal ganglia. Dr. SheikhBahaei completed his doctoral studies in Neuroscience (2017) jointly under NIMH/NINDS – University College London (UCL) Graduate Partnership Program where he worked with Drs. Jeffrey Smith (NINDS) and Alexander Gourine (UCL). His graduate studies were on how astrocytic networks control activities of respiratory motor circuits within the brainstem. After short postdoctoral research at NINDS, Dr. SheikhBahaei became an Independent Research Scholar in 2019. In collaboration with t ....
Image Credit: Andrey Armyagov/Shutterstock Refractory metal alloys are known for their distinctive specifications and general properties. Among them is the niobium-based refractory metal alloy C-103, which has a variety of applications in space exploration and propulsion technologies. Though elements such as molybdenum, tantalum, tungsten, niobium, and rhenium are the more well-known refractory metals, this category can be expanded to include up to 16 metallic elements. 1,2,3,4 Refractory metals all have some core properties in common. These include exceptional resistance to corrosion, high thermal conductivity and melting points, as well as the retention of mechanical strength at high temperatures (hot strength). Given the durable and hard-wearing properties of refractory elements, they have been the subject of research for applications in a wide range of fields. These include nuclear power, aerospace applications, drilling, metal cutting, chemical processing� ....
. 1–4 It is possible to combine these elements, both with other materials and with each other, to create a wide range of high-performance refractory metal compounds and alloys, which are fundamental to several industries. This article examines the main applications of refractory metals and the range of compounds and alloys in which they are used. Aerospace and Defense The defense and aerospace industries require materials with superior thermal and mechanical durability. For defense and aerospace applications, refractory metals are an essential class of materials as they supply a foundation for strength retention to temperatures as high as 2200°C. Niobium is especially useful for applications in aerospace because of its comparatively low density, which is equivalent to that of nickel. ....
