The Influence Of Cobalt And Molybdenum On The Microstructure And Mechanical Properties Of High Cobalt-Chromium-Molybdenum Bearing Steel

Cobalt-chromium-molybdenum alloy (CoCrMo) is one of the cobalt-based alloys, and is also a kind of Stellite alloy, which is a kind of cobalt-based alloy that is resistant to wear and corrosion. The first cobalt-based alloy was a binary cobalt-chromium alloy, which was later developed into a ternary composition of cobalt-chromium-tungsten, and only later did cobalt-chromium-molybdenum alloys. […]

Highly catalytically active niobium carbide (MXene) promotes hematopoietic recovery after radiation through free radical scavenging

Ionizing radiation (IR) is widely used in industry and radiotherapy, but nuclear or radiological accidents have seriously endangered the health of related personnel, and inevitably bring some injuries in radiotherapy. In this work, ultra-thin two-dimensional (2D) niobium carbide (Nb2C) MXene was developed as a radiation protection agent and applied to remove oxygen radicals induced by […]

Graphene merchandise are ‘faux’

Graphite, additionally called multilayer graphene, is made from layers of carbon atoms, every just one bit thick, and its shape determines its advanced properties. When graphite sheets are reduced to only some layers of graphene, important features that include the entire floor place in keeping with the unit mass of the material and the mechanical […]
