Fast Neutron Detector Based on Hybrid 2D Perovskite Thin Films

Advanced Functional Materials, EarlyView.
This work presents the direct detection of fast neutrons using flexible hybrid 2D perovskite (PEA2PbBr4) thin‐film detectors. Thanks to their high low‐Z elements content and good charge transport, these materials enable efficient neutron detection. The thin film configuration allowed the operation at low voltage, and offer scalability, flexibility, and

Hot water epilepsy: Phenotype and single photon emission computed tomography observations

Annals of Indian Academy of Neurology, 2014
We studied the anatomical correlates of reflex hot water epilepsy (HWE) using multimodality investigations viz. magnetic resonance imaging (MRI), electroencephalography (EEG), and single photon emission computed tomography (SPECT). Five men (mean age: 27.

Single-photon emission computed tomography of the normal liver [PDF]

American Journal of Roentgenology, 1983
Single-photon emission computed tomography (SPECT) is a new imaging method that offers the advantage of cross-sectional imaging and improved contrast resolution as compared with conventional planar imaging. Preliminary SPECT studies of the liver for detection of metastatic disease are very promising.

1D Light‐Emitting MAPbBr3 Perovskite Encapsulated in Carbon Nanotubes

Advanced Functional Materials, EarlyView.
Encapsulation of MAPbBr3 perovskite in single‐walled carbon nanotubes (SWCNTs) yields a hybrid nanomaterial with distinctive optoelectronic properties. Perovskite confinement induces a unified single‐peak photoluminescence (PL) with a reduced lifetime, while charge transfer alters the optical properties of nanotubes.
