We have investigated the photophysical properties of solid films of fullerene, C60, by means of photoinduced absorption and electric field modulation in metal-insulator-semiconductor (MIS) devices. Impedance analysis of the MIS devices has been used

First-order transitions to dilute stage 1 from stages 2--4 and from mixed stages are observed in Li-graphite compounds in the range 430--1020 K. The resulting (T,x) phase boundary agrees generally with predictions by Safran and others except for a sh

The stability under static vacuum of graphite nitrate produced from Grade 2135 and Micro 250 graphite has been monitored gravimetrically and via mass spectrometry of the evolved products. The gasses contain CO and CO 2 , indicating that the graphite

Dramatic differences in structure, elastic properties, and order-disorder temperatures are observed for stage-2 Li-graphite of different in-plane density, indicating the importance of long-range interactions in cohesive properties. LiC/sub 12/ is thr

A comparative study was made of the friction and wear properties of homopolymers and copolymers (with methyl methacrylate (MMA)) of methyl α-n-hexadecylacrylate (MHDA), methyl α-n-octadecylacrylate (MODA) and n-octadecyl methacrylate (ODMA). In the

Room-temperature measurements of the c-axis compressibility and longitudinal phonon dispersion (qparallelc) are reported for the stage-1 ternary graphite compound KHgC/sub 4/. Both the direct measurement and the small-q slope of the LA branch give K

Many of the mono-, di-, and trivalent cations in the periodic chart diffuse rapidly in the β″-alumina structure. β″-Aluminas containing multivalent cations can be synthesized by ion exchange reactions starting with the sodium form of the compou
