The occurrence of adsorbate-induced substrate reconstruction provides a striking demonstration of collective interactions in surface phenomena.

Radial distributions of axial stress across B/Ge- and Sn/Ge-codoped core fibers and a Corning standard single-mode fiber were measured before and after hydrogen loading under different conditions.

Plasma hydrogenation of MOCVD-grown GaAs-on-Si increases the reverse breakdown voltage of Schottky diode structures by a factor of three.

Shallow donor levels due to Si, Ge, Sn, S, Se, and Te in GaAs are neutralized by association with atomic hydrogen; Si and Te donors in ALGaAs have also been shown to be neutralized.

Hydrolysis of polyimides used as dielectrics is of concern because the formation of polar, hydrophillic products could significantly increase the dielectric losses.

Hydrolytic degradation was studied for a thermoplastic elastomer comprising polybutylene (terephthalate-co-isophthalate) hard segments and polypropylene oxide soft segments.

The power spectra of geomagnetic field fluctuations in the hydromagnetic wave band of periods 20 to 600s have been systematically evaluated from data acquired at L'Aquila, Italy (LAMBDA ~ 42.

A brief description is presented of some recent analyses of ULF (D.C. to ~0.1 Hz) and VLF (~1 kHz) magnetic field investigations made at the South Pole.

The dayside cusp region is a window on solar wind-magnetosphere coupling processes.
