Thermal Shock Synthesis
Thermal shock synthesis (TSS) is a method in which materials are synthesized via rapid, high-temperature heating. In the TSS process, temperatures as high as 3000 K are applied for a duration of just seconds or milliseconds, followed by rapid cooling (a TSS image shown in Fig. 1). In this regard, TSS is distinct from conventional high-temperature syntheses that feature slow and near-equilibrium heating at limited temperature ranges (e.g., 1500 K for furnace heating) for extended periods of time (typically hours) and generally slow heating and cooling (~10 K/min). TSS utilizes high temperature to drive reactions at extreme and non-equilibrium conditions. Additionally, the use of the ultra-high temperature can dramatically increase reaction rates for rapid material production. As a result of these characteristics, TSS is particularly applicable for the discovery of new reactions and materials and enabling rapid manufacturing. Realization The TSS method was invented by Dr. Liangbing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Maryland, College Park
The University of Maryland, College Park (University of Maryland, UMD, or simply Maryland) is a public land-grant research university in College Park, Maryland. Founded in 1856, UMD is the flagship institution of the University System of Maryland. It is also the largest university in both the state and the Washington metropolitan area, with more than 41,000 students representing all fifty states and 123 countries, and a global alumni network of over 388,000. Together, its 12 schools and colleges offer over 200 degree-granting programs, including 92 undergraduate majors, 107 master's programs, and 83 doctoral programs. UMD is a member of the Association of American Universities and competes in intercollegiate athletics as a member of the Big Ten Conference. The University of Maryland's proximity to the nation's capital has resulted in many research partnerships with the federal government; faculty receive research funding and institutional support from many agencies, such as ...

Temporal Resolution
Temporal resolution (TR) refers to the discrete resolution of a measurement with respect to time. Physics Often there is a trade-off between the temporal resolution of a measurement and its spatial resolution, due to Heisenberg's uncertainty principle. In some contexts, such as particle physics, this trade-off can be attributed to the finite speed of light and the fact that it takes a certain period of time for the photons carrying information to reach the observer. In this time, the system might have undergone changes itself. Thus, the longer the light has to travel, the lower the temporal resolution. Technology Computing In another context, there is often a tradeoff between temporal resolution and computer storage. A transducer may be able to record data every millisecond, but available storage may not allow this, and in the case of 4D PET imaging the resolution may be limited to several minutes. Electronic displays In some applications, temporal resolution may instead ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High-entropy-alloy Nanoparticles
High-entropy-alloy nanoparticles (HEA-NPs) are nanoparticles having High-entropy alloy, five or more elements alloyed in a single-phase solid solution structure. HEA-NPs possess a wide range of compositional library, distinct alloy mixing structure, and nanoscale size effect, giving them huge potential in catalysis, energy, environmental, and biomedical applications. Enabling synthesis HEA-NPs are a structural analog to bulk high-entropy alloys (HEAs), but synthesized at the nanoscale. The formation of HEAs typically requires high temperature for multi-element mixing; however, high temperature acts against Self-assembly of nanoparticles, nano-material synthesis due to high-temperature-induced structure aggregation and surface reconstruction. In 2018, HEA-NPs were firstly synthesized by a carbothermal shock synthesis. (The material and technology are patented.) The carbothermal shock employs a rapid high-temperature heating (e.g. 2000 K, in 55 ms) to enable the non-equilibrium synth ...
