“…Here, we report the discovery of a phase transition whose mechanism is identified as interlayer sliding in lead iodides, a layered material widely used to synthesize lead halide perovskites. The low-temperature crystal structure of lead iodides is found not 2H polytype as known before, but non-centrosymmetric 4H polytype. …”

“…The Planar and SPECT scans for a (99m)Tc point source and a Jaszczak Phantom with the both experiment and simulated systems were prepared and after verification and validation of the simulated system, the similar scans of the phantoms were compared (from the point of view of the images’ quality), namely, the simulated system with the detectors including bismuth germanate (BGO), yttrium aluminum garnet (YAG:Ce), Cerium-doped yttrium aluminum garnet (YAG:Ce), yttrium aluminum perovslite (YAP:Ce), lutetium aluminum garnet (LuAG:Ce), cerium activated lanthanum bromide (LaBr3), cadmium zinc telluride (CZT), and sodium iodide activated with thallium [NaI(Tl)]. …”

“…Although single-mode operation has been demonstrated in various resonator architectures with a large variety of gain media—including dye-doped polymers, organic semiconductors, and, more recently, hybrid perovskites—the reported linewidths are typically on the order of a fraction of a nanometer or broader, i.e., the coherence lengths are no longer than a few millimeters, which does not enable high-resolution spectroscopy or coherent sensing. …”

“…Cs(+) exhibits a pronounced structure-directing effect where a mixture of Cs(+) and G cations forms mono- and bilayered two-dimensional perovskites: CsGSnBr(4) and Cs(2)GSn(2)Br(7). Furthermore, the flat shapes of the guanidinium cations induce anisotropic out-of-plane tilts of the [SnBr(6)](4–) octahedra in the CsGSnBr(4) and Cs(2)GSn(2)Br(7) compounds. …”
