Electron microscopy of forming enamel

Archives of Oral Biology, 1961
Abstract A cell membrane separating the cytoplasm of the ameloblast from newly formed enamel was demonstrated in ultra-thin sections obtained from tooth germs of young rats. Study of the submicroscopic organization of the formative zone of the enamel indicates that a granular “precursor substance” synthesized by the ameloblasts is secreted into the ...

The Form of the Effective Electronic Potential in a Crystal

Proceedings of the Physical Society. Section B, 1956
The equations for the best single-electron orbitals in a crystal are interpreted in terms of an effective potential and the forms of the various contributions to this potential are considered. The exchange terms are important and act like an attractive potential which moves through the crystal.

Electronic Form Design

2018
With technological innovation and emergence of the World Wide Web, digital forms of information surround us today more than ever. It is common for us to access information online with computational devices, rather than in paper and other analog media. Today information is fluid, always up-to-date without interruption.

Form and content in the electronic age

Proceedings. Socioeconomic Dimensions of Electronic Publishing Workshop, 2002
The emerging culture of fully electronic publishing will considerably change the scientific communication process. At the moment, the emphasis is put mainly on the logistics and the storage of electronic documents as such. We address the issue of changes in the representation of scientific communications due to the intrinsic possibilities of the ...

Twenty forms of electron holography

Ultramicroscopy, 1992
Abstract Since the original proposal by Gabor for the use of holography as a means for the improvement of the resolution of electron microscopes, a number of schemes for electron holography have been proposed and several of these have been demonstrated experimentally. These include the in-line holography in transmission electron microscopy (TEM), i.e.

The Role of Secondary Electrons in Forming the Image of Electron Nanoprobe

Fullerenes, Nanotubes and Carbon Nanostructures, 2008
Formation of a lithographic image (a pixel) of electron nano‐probe has been studied using fullerite C60 film as a negative electron beam resist. A mechanism of widening a pixel due to modification of the resist by secondary electrons has been revealed. Widening a pixel occurs due to diffusion of secondary electrons around the area filled by primary and

Electron beam forming in MEMS-type electron gun

2015 28th International Vacuum Nanoelectronics Conference (IVNC), 2015
In this paper we discuss first realization and preliminary parameters of the electronoptics MEMS column equipped with a field-emitting electron gun and an Einzel lens. The column is made in a form of the sandwiched silicon stack. Silicon elements are deep wet micromachined and placed in a polymer 3D printed holder.

Asymptotic Form of the Electron Propagator and the Self-Mass of the Electron

Physical Review D, 1971
The electron self-mass problem is discussed in the context of ordinary renormalized quantum electro-dynamics. All perturbation contributions to the renormalized self-energy part $\ensuremath{\Sigma}(p)$, which diverge logarithmically or remain constant in the limit when $p\ensuremath{\gg}m$, are summed.

Going Paperless - On the Evaluation of Electronic Form Technologies

2011 22nd International Workshop on Database and Expert Systems Applications, 2011
Most organizations rely on the use of forms for their daily business. These forms are more and more replaced by electronic equivalents. This change is usually a significant investment, therefore it is important to understand the requirements and features of available systems.
