There are a wide range of applications with ionizing radiation and a common theme throughout these is that accurate dosimetry is usually required, although many newer demands are provided by improved features in higher range, multi-spectral and particle type detected. Today, the array of dosimeters includes both offline and online tools, such as gel dosimeters, thermoluminescence (TL), scintillators

Controlling the manner of band alignment of heterostructures increases design freedom with novel physical properties, enables the design of new functional devices, and improves device performance, but the lattice matching limits the diversity of traditional heterostructures. Van der Waals heterostructures (vdWHs) fabricated by rationally mechanical restacking different two-dimensional (2D) layered

Multicolor organic room temperature phosphorescence (RTP) has garnered wide research attention due to the long luminescence lifetime and tunable excited state properties, which show great potential in displays, anticounterfeiting, data encryption, and sensing. However, because of the sensitivity of triplet excitons of organic materials, the triplet emitting level of organic compounds is hard to manipulate

To develop efficient and durable acidic oxygen–reduction–reaction (ORR) catalysts based on all platinum group metals (PGMs) is crucial for large-scale application of proton-exchange membrane fuel cells (PEMFCs) but challenging. Here, we report a nitrogen coordination-induced strong metal–support interaction that can tune the surface atoms of ORR-inactive PGM clusters into efficient and durable active
