Tuning morphological features of lead iodide by low pressure vapor phase deposition
(Elsevier Science Sa, 2018-05)
Lead iodide (PbI2) is a semiconductor with extensive use as an active layer for X-ray detectors and as a precursor for perovskite solar cells. Here we present a low vacuum method to obtain very uniform PbI2 films with full ...
Columnar jointing in vapor-phase-altered, non-welded Cerro Galán Ignimbrite, Paycuqui, Argentina
(Springer Verlag Berlín, 2011-09)
Columnar jointing is thought to occur primarily in lavas and welded pyroclastic flow deposits. However, the non-welded Cerro Galán Ignimbrite at Paycuqui, Argentina, contains well-developed columnar joints that are instead ...
Increased sulfur tolerance of Pt/KL catalysts prepared by vapor-phase impregnation and containing a Tm promoter
(Elsevier, 2000-04)
Pt/KL catalysts are highly active and selective for the aromatization of hexane, but they display a very high sensitivity to even small concentrations of sulfur in the feed. Tm-containing Pt/KL catalysts were prepared by ...
