Owing to the solid-state phase transition of the PU PCM, only 0.6% of energy storage loss occurred over 100 repeated heating and cooling cycles. It is shown that the concentrate has a high chemical stability against the interaction with sulfuric solutions 1 decade ago. The phase composition of layer changes depending on theconditions of the polymer initial treatment in a TeS4O62– solution. Monatsh., 9, 199–204 (1961) in German. This bond length difference has been ascribed to the higher bond order in (S-S)− compared to (S-S)2− due to electrons being removed from a π* antibonding orbital. Different stoichiometric compositions can be obtained by changing the redox atmosphere of the synthetic environment. The thickness of the inner-disk layer can be tuned to form two-dimensional (2D), single atomic layers (<1 nm). Miner., 56, 1189–1909 (1971). Chem.

Vol.,39A, 243–263 (1970) quoted in [77Pot]. II. Copper sulfide-based semiconductors are particularly interesting in this regard, because of the many possible copper sulfide phases, the appearance of localized surface plasmon resonance in copper-deficient phases, and the ease with which copper sulfide phases can undergo cation incorporation or exchange to produce new binary, ternary, or even quaternary materials. Whatever their source, copper sulfides vary widely in composition with 0.5 ≤ Cu/S ≤ 2, including numerous non-stoichiometric compounds. (Equi Diagram; Experimental), 55Don: J. D. H.
