To the Editor.— Wolbarsht et al1 advanced several hypotheses in their letter regarding the role of CO2 in retrolental fibroplasia. We take issue with their letter on the following grounds: 1. No evidence is presented that levels of retinal Pco2 rise during O2 induced retinal vasoconstriction. CO2 has a high diffusion coefficient, 20 times that of oxygen2 and we suggest that such CO2 produced in the retina would rapidly diffuse the short distance to the high-flow choroidal circulation. 2.

Method of calculation and calculated values of parameters of elementary nanocrystals of liquid metals at melting temperature are given. It has been shown that radii of elementary nanocrystals are from 2 nm to 12 nm, and the number of atoms in each elementary nanocrystal varies from 2000 to 100000. This provides liquid metals with a high solidification rate and explains the abnormally high diffusion coefficient in liquid metals compared to solid metals.

Diffusion Of Hydrogen

ABSTRACTTime evolution of Si dangling bonds (dbs) was monitored during atomic hydrogen treatment of a-Si:H films using an in-situ electron-spin-resonance (ESR) technique. A high diffusion coefficient (>10−10 cm2s−1) of free atomic H in a-Si:H was detected at the very initial stage of H exposure. Atomic H diffuses into the bulk of the film (∼100 nm) and creates additional metastable dbs. The spatial distribution of such metastable dbs becomes deeper at lower treatment temperatures. An activated type of db creation reaction determines the distribution of these dbs.
