Columbia, Missouri
Columbia is a city in the U.S. state of Missouri. It is the county seat of Boone County and home to the University of Missouri. Founded in 1821, it is the principal city of the five-county Columbia metropolitan area. It is Missouri's fourth most-populous and fastest growing city, with an estimated 126,254 residents in 2020. As a Midwestern college town, Columbia has a reputation for progressive politics, persuasive journalism, and public art. The tripartite establishment of Stephens College (1833), the University of Missouri (1839), and Columbia College (1851), which surround the city's Downtown to the east, south, and north, has made the city a center of learning. At its center is 8th Street (also known as the Avenue of the Columns), which connects Francis Quadrangle and Jesse Hall to the Boone County Courthouse and the City Hall. Originally an agricultural town, education is now Columbia's primary economic concern, with secondary interests in the healthcare, insuranc ...

Academic Conference
An academic conference or scientific conference (also congress, symposium, workshop, or meeting) is an event for researchers (not necessarily academics) to present and discuss their scholarly work. Together with academic or scientific journals and Preprint archives such as arXiv, conferences provide an important channel for exchange of information between researchers. Further benefits of participating in academic conferences include learning effects in terms of presentation skills and “academic habitus”, receiving feedback from peers for one’s own research, the possibility to engage in informal communication with peers about work opportunities and collaborations, and getting an overview of current research in one or more disciplines. Overview Conferences usually encompass various presentations. They tend to be short and concise, with a time span of about 10 to 30 minutes; presentations are usually followed by a . The work may be bundled in written form as academic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scientific Journal
In academic publishing, a scientific journal is a periodical publication intended to further the progress of science, usually by reporting new research. Content Articles in scientific journals are mostly written by active scientists such as students, researchers, and professors instead of professional journalists. There are thousands of scientific journals in publication, and many more have been published at various points in the past (see list of scientific journals). Most journals are highly specialized, although some of the oldest journals such as '' Nature'' publish articles and scientific papers across a wide range of scientific fields. Scientific journals contain articles that have been peer reviewed, in an attempt to ensure that articles meet the journal's standards of quality and scientific validity. Although scientific journals are superficially similar to professional magazines, they are actually quite different. Issues of a scientific journal are rarely read ...

Energy Conversion
Energy transformation, also known as energy conversion, is the process of changing energy from one form to another. In physics, energy is a quantity that provides the capacity to perform work or moving, (e.g. Lifting an object) or provides heat. In addition to being converted, according to the law of conservation of energy, energy is transferable to a different location or object, but it cannot be created or destroyed. The energy in many of its forms may be used in natural processes, or to provide some service to society such as heating, refrigeration, lighting or performing mechanical work to operate machines. For example, to heat a home, the furnace burns fuel, whose chemical potential energy is converted into thermal energy, which is then transferred to the home's air to raise its temperature. Limitations in the conversion of thermal energy Conversions to thermal energy from other forms of energy may occur with 100% efficiency. Conversion among non-thermal forms of energy ...

Energy Storage
Energy storage is the capture of energy produced at one time for use at a later time to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an accumulator or battery. Energy comes in multiple forms including radiation, chemical, gravitational potential, electrical potential, electricity, elevated temperature, latent heat and kinetic. Energy storage involves converting energy from forms that are difficult to store to more conveniently or economically storable forms. Some technologies provide short-term energy storage, while others can endure for much longer. Bulk energy storage is currently dominated by hydroelectric dams, both conventional as well as pumped. Grid energy storage is a collection of methods used for energy storage on a large scale within an electrical power grid. Common examples of energy storage are the rechargeable battery, which stores chemical energy readily convertible to electricity to opera ...

Thermal Management (electronics)
All electronic devices and circuitry generate excess heat and thus require thermal management to improve reliability and prevent premature failure. The amount of heat output is equal to the power input, if there are no other energy interactions. There are several techniques for cooling including various styles of heat sinks, thermoelectric coolers, forced air systems and fans, heat pipes, and others. In cases of extreme low environmental temperatures, it may actually be necessary to heat the electronic components to achieve satisfactory operation. Overview Thermal resistance of devices This is usually quoted as the thermal resistance from junction to case of the semiconductor device. The units are °C/W. For example, a heatsink rated at 10 °C/W will get 10 °C hotter than the surrounding air when it dissipates 1 Watt of heat. Thus, a heatsink with a low °C/W value is more efficient than a heatsink with a high °C/W value. Given two semiconductor device ...

Nanomanufacturing
Nanomanufacturing is both the production of nanoscaled materials, which can be powders or fluids, and the manufacturing of parts "bottom up" from nanoscaled materials or "top down" in smallest steps for high precision, used in several technologies such as laser ablation, etching and others. Nanomanufacturing differs from molecular manufacturing, which is the manufacture of complex, nanoscale structures by means of nonbiological mechanosynthesis (and subsequent assembly). The term "nanomanufacturing" is widely used, e.g. by the European Technology Platform MINAM and the U.S. National Nanotechnology Initiative (NNI). The NNI refers to the sub-domain of nanotechnology as one of its five "priority areas." There is also a nanomanufacturing program at the U.S. National Science Foundation, through which thNational Nanomanufacturing Network (NNN)has been established. The NNN is an organization that works to expedite the transition of nanotechnologies from laboratory research to production ...

Mass Transfer
Mass transfer is the net movement of mass from one location (usually meaning stream, phase, fraction or component) to another. Mass transfer occurs in many processes, such as absorption, evaporation, drying, precipitation, membrane filtration, and distillation. Mass transfer is used by different scientific disciplines for different processes and mechanisms. The phrase is commonly used in engineering for physical processes that involve diffusive and convective transport of chemical species within physical systems. Some common examples of mass transfer processes are the evaporation of water from a pond to the atmosphere, the purification of blood in the kidneys and liver, and the distillation of alcohol. In industrial processes, mass transfer operations include separation of chemical components in distillation columns, absorbers such as scrubbers or stripping, adsorbers such as activated carbon beds, and liquid-liquid extraction. Mass transfer is often coupled to additi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Research Scientist
A scientist is a person who conducts scientific research to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales (circa 624-545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. In modern times, many scientists have advanced degrees in an area of science and pursue careers in various sectors of the economy such as academia, industry, government, and nonprofit environments.''''

Research Associate
Research associates are researchers (scholars and professionals) that usually have an advanced degree beyond a Master's degree. In some universities/research institutes, such as Harvard/Harvard Medical School/Harvard School of Public Health, the candidate holds the degree of Ph.D. or possess training equivalent to that required for the Ph.D. In addition, the candidate must have demonstrated exceptional fitness in independent research. This position allows the candidate to enlarge professional network, get more experience, get publications, fellowships, grants to establish independence as a PI or start looking for a more secure permanent job. It can advance to Senior Research Associate (higher pay with more responsibilities equivalent to a PI), Research Scientist, Senior Research Scientist, Principal Research Scientist, and later Head of Research or equivalent. In contrast to a research assistant, a research associate often has a graduate degree, such as a master's (e.g. Master ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Doctor Of Engineering
The Doctor of Engineering, or Engineering Doctorate, (abbreviated DEng, EngD, or Dr-Ing) is a degree awarded on the basis of advanced study and a practical project in the engineering and applied science for solving problems in the industry. In the United States, it is a terminal professional doctorate. A DEng/EngD is equivalent to a PhD in engineering, but different in that it has a solid industrial base and an additional taught element. The degree is usually aimed toward working professionals. The DEng/EngD along with the PhD represents the highest academic qualification in engineering, and the successful completion of either in engineering is generally required to gain employment as a full-time, tenure-track university professor or postdoctoral researcher in the field. However, due to its nature, a DEng/EngD graduate might be more suitable for the Professor of Practice position. Individuals can use the academic title doctor, which is often represented via the English honorific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
