Akiko Hisada Makoto Nakabayashi Minami Shoji Mai Yoshihara Kenichi Sato Sukehiro Ito OVERVIEW: Hitachi High-Technologies developed the AE1500, a tabletop atmospheric SEM that is capable of scanning electron microscopy under atmospheric pressure, by using a membrane that allows an electron beam to pass while keeping the atmospheric-pressure chamber and evacuated column separate. Because the specimen does not come into contact with the membrane, a feature of the AE1500 is its ability to observe bulk specimens under atmospheric pressure. Hitachi High-Technologies also developed the ES-Corrector algorithm to correct the image for the electron beam scattering that occurs due to the presence of atmospheric gases between the membrane and the specimen. This means that bulk, high-moisture specimens such as food or biological samples can be observed with the electron microscope under atmospheric pressure without preprocessing.

Observation of Wet Samples Using a Novel Atmospheric Scanning Electron Microscope
The scanning electron microscope (SEM) has been used as a powerful tool for providing surface information of micro and nanostructures. In recent years, SEM methods for observing wet samples under atmospheric pressure have been reported by some investigators [1-2]. With these methods, the sample space is separated by a thin transparent membrane from vacuum environment where electron beam is prop...
متن کاملHigh pressure intensification of cassava resistant starch (RS3) yields.
Cassava starch, typically, has resistant starch type 3 (RS3) content of 2.4%. This paper shows that the RS3 yields can be substantially enhanced by debranching cassava starch using pullulanase followed by high pressure or cyclic high-pressure annealing. RS3 yield of 41.3% was obtained when annealing was carried out at 400MPa/60°C for 15 min, whereas it took nearly 8h to obtain the same yield un...
متن کاملA novel method for "Wet" SEM.
Progress in the processing of wet tissues, without the need of fixation and complex preparation procedures, may facilitate the microscopic examination of tissues and cells. Microscopic examination of tissues is a central tool in clinical diagnosis as well as in diverse areas of research. The authors present the application of Wet SEM, a technology for imaging fully hydrated samples at atmospher...
متن کاملObservation of tissues in open aqueous solution by atmospheric scanning electron microscopy: Applicability to intraoperative cancer diagnosis
In the atmospheric scanning electron microscope (ASEM), a 2- to 3-µm layer of the sample resting on a silicon nitride-film window in the base of an open sample dish is imaged, in liquid, at atmospheric pressure, from below by an inverted SEM. Thus, the time-consuming pretreatments generally required for biological samples to withstand the vacuum of a standard electron microscope are avoided. In...
