Ultra-high temperature ceramics (UHTCs) are a class of materials that can be used in environments that exhibit extremes in temperature, chemical reactivity, erosive attack, etc.
Magnetoelectric (ME) materials are those in which an external magnetic field affects the polarization, and an electric field influences the magnetization of the material. A well-known example of the ME material is Cr2O3.
Currently, surgeons use two primary types of materials inside the body to replace damaged body parts: either common industrial materials or harvested natural materials. In order to replace these biochemical functions, harvested natural materials are generally the gold standard.
Diamond is highly attractive as a laser material as it promises capabilities well beyond that possible from other materials in accordance with its extreme properties.
Atom Probe Tomography (APT) represents a revolutionary characterization tool for materials that can image individual atoms in three dimensions, a major advancement over the two dimensional images of other microscopy techniques.
Among the twelve principles of green science and technology is a desire that the production of materials be achieved from sustainable sources with minimal environmental impact, and preferably by recycling of waste materials.
Materiomics is defined as the study of the material properties of natural and synthetic materials by examining fundamental links between processes, structures and properties at multiple scales, by using systematic experimental, theoretical or computational methods.
The goal of clean coal research is to increase the steam temperature, which would increase efficiency. At these conditions, Ni-base superalloy blades and vanes in the turbine are protected by sophisticated film cooling systems and by thermal barrier coatings.
The scope of Green Engineering depends upon one's perspective and discipline, but it is broadly defined as minimizing environmental impacts across all life cycle phases in the design and engineering of products, processes, and systems.
