Shock compression data are reported for hot-pressed Bamble bronzite (En86) loaded to pressures between 104 and 161 GPa. When compared to earlier shock wave data on En90 at lower pressures and to static compression data, our data require the presence of a phase change. In space the data yield two distinct trajectories, which cannot be explained by experimental error. The higher-density data, cor...

Thermal to electric energy conversion with thermophotovoltaics relies on radiation emitted by a hot body, which limits the power per unit area to that of a blackbody. Microgap thermophotovoltaics take advantage of evanescent waves to obtain higher throughput, with the power per unit area limited by the internal blackbody, which is n2 higher. We propose that even higher power per unit area can b...
