WebApr 12, 2024 · The schematic of the PRILD is shown in Fig. 1A.The filament of the PRILD is an all-ceramic Janus thermal emitter (JTE) strip (), which consists of a hexagonal boron nitride (hBN) white emitter and a carbon nanotube (CNT) black emitter (see Materials and Methods and fig. S1).The JTE is suspended inside of a ceramic corundum cavity (CCC). WebIsosteric heats of adsorption of nitrogen on diamond, annorphous carbon, and thermally graphitized P 33 differed very little at the coverage approaching completion of the first monolayer. The effect of the much greater density of diamond was thus balsnced by a correspondingly greater contribution (per atom) from the electrons of the graphitic carbons.
