Killing Of Zijie Yan
On August 28, 2023, Zijie Yan, an associate professor at the University of North Carolina (UNC) in Chapel Hill, North Carolina, United States, was shot and killed on campus. 34-year-old Tailei Qi, one of his graduate students, was arrested and charged with first-degree murder. The shooting sent the university into lockdown for three hours. Persons involved Zijie Yan Zijie Yan (; – August 28, 2023) was from the city of Jingmen, Hubei Province in central China. He received dual bachelor's degrees in materials and computer science in 2005 and a master's degree in physical electronics in 2007 from the Huazhong University of Science and Technology in Wuhan, Hubei Province. He completed his PhD at Rensselaer Polytechnic Institute in 2011. While still learning English, he published 17 research articles during his time at Rensselaer.

Yan (surname)
Yan is a surname in several languages and the pinyin romanization for several Chinese surnames, including " ()", " ()", " ()", " ()", " ()", " ()", " ()", " ()", " ()" in simplified (traditional) form. These characters are romanised as ''Yen'' in the Wade–Giles romanization system which was commonly used before the early 80s. As such, individuals and institutions who had to romanize their Chinese names prior to that time, such as when having their books translated or publishing manuscripts outside of China, used "Yen" instead of "Yan". Such examples include Yenching University and the Harvard-Yenching Institute. The Yan surname in Taiwan is mostly spelled as Yen since only until recently has the government approved the use of pinyin romanization of names. The Cantonese romanization of these surnames is "Yim". As such, most people from Hong Kong and Chinese diaspora that emigrated prior to 1949 from Guangdong use the name Yim. On many occasions, the surname " ()" is also roman ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Master Of Science
A Master of Science (; abbreviated MS, M.S., MSc, M.Sc., SM, S.M., ScM or Sc.M.) is a master's degree. In contrast to the Master of Arts degree, the Master of Science degree is typically granted for studies in sciences, engineering and medicine and is usually for programs that are more focused on scientific and mathematical subjects; however, different universities have different conventions and may also offer the degree for fields typically considered within the humanities and social sciences. While it ultimately depends upon the specific program, earning a Master of Science degree typically includes writing a thesis. The Master of Science degree was introduced at the University of Michigan in 1858. One of the first recipients of the degree was De Volson Wood, who was conferred a Master of Science degree at the University of Michigan in 1859. Algeria Algeria follows the Bologna Process. Australia Australian universities commonly have coursework or research-based Master o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Founded in the autumn of 1869, ''Nature'' was first circulated by Norman Lockyer and Alexander MacMillan (publisher), Alexander MacMillan as a public forum for scientific innovations. The mid-20th century facilitated an editorial expansion for the j ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Optical Tweezers
Optical tweezers (originally called single-beam gradient force trap) are scientific instruments that use a highly focused laser beam to hold and move microscopic and sub-microscopic objects like atoms, nanoparticles and droplets, in a manner similar to tweezers. If the object is held in air or vacuum without additional support, it can be called optical levitation. The laser light provides an attractive or repulsive force (typically on the order of piconewtons), depending on the relative refractive index between particle and surrounding medium. Levitation is possible if the force of the light counters the force of gravity. The trapped particles are usually micron-sized, or even smaller. Dielectric and absorbing particles can be trapped, too. Optical tweezers are used in biology and medicine (for example to grab and hold a single bacterium, a cell like a sperm cell or a blood cell, or a molecule like DNA), nanoengineering and nanochemistry (to study and build materials from ...

Nanoparticle
A nanoparticle or ultrafine particle is a particle of matter 1 to 100 nanometres (nm) in diameter. The term is sometimes used for larger particles, up to 500 nm, or fibers and tubes that are less than 100 nm in only two directions. At the lowest range, metal particles smaller than 1 nm are usually called atom clusters instead. Nanoparticles are distinguished from microparticles (1-1000 μm), "fine particles" (sized between 100 and 2500 nm), and "coarse particles" (ranging from 2500 to 10,000 nm), because their smaller size drives very different physical or chemical properties, like colloidal properties and ultrafast optical effects or electric properties. Being more subject to the Brownian motion, they usually do not sediment, like colloid, colloidal particles that conversely are usually understood to range from 1 to 1000 nm. Being much smaller than the wavelengths of visible light (400-700 nm), nanoparticles cannot be seen with ordinary ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Postdoctoral Fellow
A postdoctoral fellow, postdoctoral researcher, or simply postdoc, is a person professionally conducting research after the completion of their doctoral studies (typically a PhD). Postdocs most commonly, but not always, have a temporary academic appointment, sometimes in preparation for an academic faculty position. According to data from the US National Science Foundation, the number of holders of PhD in biological sciences who end up in tenure track has consistently dropped from over 50% in 1973 to less than 20% in 2006. They continue their studies or carry out research and further increase expertise in a specialist subject, including integrating a team and acquiring novel skills and research methods. Postdoctoral research is often considered essential while advancing the scholarly mission of the host institution; it is expected to produce relevant publications in peer-reviewed academic journals or conferences. In some countries, postdoctoral research may lead to further form ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
