Jeol 5sector
is a major developer and manufacturer of electron microscopes and other scientific instruments, industrial equipment and medical equipment. Its headquarters are in Tokyo, Japan, with 25 domestic and foreign subsidiaries and associated companies as of 2014. It is listed in the top ten businesses worldwide for analytical laboratory instrument manufacturing.

It has been included in the Activest Lux Nanotech Mutual Fund and the WestLB Nanotech Fund. History Scientists in Japan began to collaborate as early as 1939 on the development of an electron microscope. Kenji Kazato and Kazuo Ito met while working at the Naval Central Institute in Tokyo during World War II. After the war, Kazato attracted Ito and a group of others to Mobara, Chiba Prefecture, Japan. This initial group developed a prototype magnetic field–type electron microscope called the D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Public Company
A public company is a company whose ownership is organized via shares of stock which are intended to be freely traded on a stock exchange or in over-the-counter markets. A public (publicly traded) company can be listed on a stock exchange (listed company), which facilitates the trade of shares, or not (unlisted public company). In some jurisdictions, public companies over a certain size must be listed on an exchange. In most cases, public companies are ''private'' enterprises in the ''private'' sector, and "public" emphasizes their reporting and trading on the public markets. Public companies are formed within the legal systems of particular states, and therefore have associations and formal designations which are distinct and separate in the polity in which they reside. In the United States, for example, a public company is usually a type of corporation (though a corporation need not be a public company), in the United Kingdom it is usually a public limited company (plc), i ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Magnetic Resonance
Nuclear magnetic resonance (NMR) is a physical phenomenon in which nuclei in a strong constant magnetic field are perturbed by a weak oscillating magnetic field (in the near field) and respond by producing an electromagnetic signal with a frequency characteristic of the magnetic field at the nucleus. This process occurs near resonance, when the oscillation frequency matches the intrinsic frequency of the nuclei, which depends on the strength of the static magnetic field, the chemical environment, and the magnetic properties of the isotope involved; in practical applications with static magnetic fields up to ca. 20 tesla, the frequency is similar to VHF and UHF television broadcasts (60–1000 MHz). NMR results from specific magnetic properties of certain atomic nuclei. Nuclear magnetic resonance spectroscopy is widely used to determine the structure of organic molecules in solution and study molecular physics and crystals as well as non-crystalline materials. ...

Mass Spectrometer
Mass spectrometry (MS) is an analytical technique that is used to measure the mass-to-charge ratio of ions. The results are presented as a ''mass spectrum'', a plot of intensity as a function of the mass-to-charge ratio. Mass spectrometry is used in many different fields and is applied to pure samples as well as complex mixtures. A mass spectrum is a type of plot of the ion signal as a function of the mass-to-charge ratio. These spectra are used to determine the elemental or isotopic signature of a sample, the masses of particles and of molecules, and to elucidate the chemical identity or structure of molecules and other chemical compounds. In a typical MS procedure, a sample, which may be solid, liquid, or gaseous, is ionized, for example by bombarding it with a beam of electrons. This may cause some of the sample's molecules to break up into positively charged fragments or simply become positively charged without fragmenting. These ions (fragments) are then separated according ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stigmator
A stigmator is a component of electron microscopes that reduces astigmatism of the beam by imposing a weak electric or magnetic quadrupole field on the electron beam. Background For early electron microscopes - between the 1940s and 1960s - astigmatism was one of the main performance limiting factors. Sources of this astigmatism include misaligned objectives, non-uniform magnetic fields of the lenses, which was especially hard to correct, lenses that aren't perfectly circular and contamination on the objective aperture.Batten, C. F. (2000). Autofocusing and astigmatism correction in the scanning electron microscope (Doctoral dissertation, Faculty of the Department of Engineering, University of Cambridge). Therefore, to improve the resolving resolution, the astigmatism had to be corrected. The first commercially used stigmators on electron microscopes were installed in the early 1960s. The stigmatic correction is done using an electric or magnetic field perpendicular to the beam. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Peabody, MA
Peabody () is a city in Essex County, Massachusetts, United States. The population was 54,481 at the time of the 2020 United States Census. Peabody is located in the North Shore region of Massachusetts, and is known for its rich industrial history. History The area was long inhabited by Native American people known as the Naumkeag. The area was settled as part of Salem in 1626 by a small group of English colonists from Cape Ann led by Roger Conant. It was subsequently referred to as the Northfields, Salem Farms, and Brooksby. Several area residents were accused of witchcraft during the Salem witch trials of the late 17th century, three of whom were executed ( John Proctor, Giles Corey, and Martha Corey). In 1752, the area was set off from Salem, and incorporated as a district of Danvers. It was referred to as "the South Parish", associated with a church located in present-day Peabody Square. In 1855, the community broke away from Danvers, and was incorporated as the ind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transmission Electron Microscope
Transmission electron microscopy (TEM) is a microscopy technique in which a beam of electrons is transmitted through a specimen to form an image. The specimen is most often an ultrathin section less than 100 nm thick or a suspension on a grid. An image is formed from the interaction of the electrons with the sample as the beam is transmitted through the specimen. The image is then magnified and focused onto an imaging device, such as a fluorescent screen, a layer of photographic film, or a sensor such as a scintillator attached to a charge-coupled device. Transmission electron microscopes are capable of imaging at a significantly higher resolution than light microscopes, owing to the smaller de Broglie wavelength of electrons. This enables the instrument to capture fine detail—even as small as a single column of atoms, which is thousands of times smaller than a resolvable object seen in a light microscope. Transmission electron microscopy is a major analytical method in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
