THE USE OF LEAD CITRATE AT HIGH pH AS AN ELECTRON-OPAQUE STAIN IN ELECTRON MICROSCOPY

open access: yesJournal of Cell Biology, 1963
Aqueous solutions of lead salts (1, 2) and saturated solutions of lead hydroxide (1) have been used as stains to enhance the electron-scattering properties of components of biological materials examined in the electron microscope.

Polarization Effects in the Reaction d+eˉ → d+eˉ

open access: yesEast European Journal of Physics, 2021
The differential cross section and polarization observables for the elastic reaction induced by deuteron scattering off electrons at rest,  are calculated in the one-photon-exchange approximation. The following polarization observables were calculated: 1-

Electronic Markets and Electronic Hierarchies [PDF]

open access: yesCommunications of the ACM, 1987
Abstract The innovations in information technologies of the past two decades have radically reduced the time and cost of processing and communicating information. These reductions have in turn brought many changes in the ways that tasks are accomplished in firms.

Analysis of the mineral composition of hypomineralized first permanent molars [PDF]

open access: yesVojnosanitetski Pregled, 2015
Background/Aim. Hypomineralization of molars and incisors (molar-incisor hypomineralization - MIH) is defined as enamel hypomineralization of systemic origin of one or more of the four first permanent molars, which may be associated with changes

Electron-electron interaction in multiwall carbon nanotubes [PDF]

open access: yes, 2001
Magnetic susceptibility $\chi$ of pristine and brominated arc-produced sample of multiwall carbon nanotubes was measured from 4.2 to 400 K. An additional contribution $\Delta \chi(T)$ to diamagnetic susceptibility $\chi(T)$ of carbon nanotubes was found ...

Effect of the amount of SiC, number of strokes, and applied load on the reciprocating wear behavior of Al-SiC composites

open access: yesScience and Engineering of Composite Materials, 2015
The wear behavior of Al/SiC composites prepared by stir casting technique is investigated to find out the effects of the weight percentage of SiC, load, and the number of strokes on a shaper machine.
