The work described is an extended study of the gas jet developed above the pressure limiting aperture (Bell, 1974; Lacaze <em>et al.,</em> 1977). Experiments specifically aimed to establish how the vacuum in the electron optics system was affected by the relative positioning of the objective and pressure limited aperture, as well as the pumping speeds employed, specimen chamber pressure, geometry and size of apertures, and by other means. Further, the nfluence of the jet deflectors, to control the effects of this jet on the microscope system were studied quantitatively using a specifically designed apparatus. In addition, the study of the pressure gradients below the pressure limiting aperture revealed that specimens can be placed as close as radius from the aperture and still experience an almost saturated vapour pressure environment. The results of the present study are currently being used in the design of an optimum detection configuration. A preliminary result has allowed the use of 140 μm pressure limiting aperture to observe specimens at atmospheric pressures as well as the use of low accelerating voltages (e.g. 7 kV) at TV scanning rates to record on video cassette dynamic phenomena, including wetting or recrystallizing salt solutions, etc.</p></div>","PeriodicalId":100924,"journal":{"name":"Micron (1969)","volume":"14 1","pages":"Pages 41-52"},"PeriodicalIF":0.0,"publicationDate":"1983-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0047-7206(83)90030-4","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"53860601","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The needle-like crystals of papain exhibit pronounced longitudinal and transverse periodicities and are clearly shown to be formed by the coalescence of parallel bundles of individual fibrils. Optical diffractometry performed on suitable regions of the electron micrographs containing papain crystals have been employed to produce the optical transform for subsequent image filtering. Transverse thin sections of the thicker crystals reveals a complex honeycomb organization with pronounced aqueous channels. This organization is held to be responsible for the varying images of the negatively stained crystals, which result from the varying orientations of the crystal axis relative to the electron beam. It is proposed that papain may represent another useful protein for studying electron microscopically the fibre-to-crystal transformation process, as well as for the understanding of the formation of varying crystalline states.</p></div>","PeriodicalId":100924,"journal":{"name":"Micron (1969)","volume":"14 2","pages":"Pages 147-164"},"PeriodicalIF":0.0,"publicationDate":"1983-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0047-7206(83)90017-1","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"53860722","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
