It is based on the assumption that PbI and I, respectively SnI and I, resulting from the PbI2 (SnI2) dissociations, are incorporated independently and specifically in the crystals: in PbTe prevails the PbI-incorporation; in SnTe — the incorporation of I + VSn. This difference is connected ...

(developed to overcome a British naval blockade) used ashes of iodine-rich seaweed as one of its ingredients. It was while cleaning out waste deposits with acid and heat that Courtois noticed beautiful violet-colored vapors that deposited as metal-like black crystals on the cooler surfaces of ...
On iodine behaviour in bulk crystals of PbTe and SnTe synthesized by the iodide method In order to explain the peculiar characteristics of iodidely synthesized PbTe and SnTe crystals a model for their interaction with iodine is suggested. It ... EP Trifonova,L Karagiozov - 《Crystal Research ...
(The record is held by iodine's neighbour xenon: the Xe–Xe bond length is 308.71 pm.)[28] As such, within the iodine molecule, significant electronic interactions occur with the two next-nearest neighbours of each atom, and these interactions give rise, in bulk iodine, to a shiny ...

5c). The X-ray diffraction results demonstrated the generation of SnI4 and SnI4(S8)2 crystals, implying that the efficient I2 capture can be attributed primarily to the chemisorption process [32]. Sign in to download hi-res image Fig. 5. (a) SEM and TEM micrographs of the chalcogels....

64. The ground-based version uses a wind tunnel to accelerate air onto the tip of the inlet, where the counterflow prevents non-activated aerosol (particles with low inertia) from entering the sample flow but allows cloud droplets and ice crystals pass through. The droplet/crystal cut size ...
The MAPbI3single crystals in our study were synthesized by a ligand-assisted growth method, which has been demonstrated to tune the facets of the crystals35. The grown crystals also have a record-low charge-trap density due to the modulation of ion addition during the solution-growth process....
