“…The LOD was calculated to be 3.06 J m À2 , which is lower than those of UO 2 (phen)(CH 3 COO)(OH) and UO 2 (5-NIPA)(DMF) and comparable with that of a colormetric crystal violet lactone (CVL) (Table S3, ESI †). 20,30,31 In addition to the UV radiation, the sensitization capacity of U-bppCOO toward X-rays was also examined. Dose dependent luminescence spectra were collected on single crystals of U-bppCOO under X-ray radiation from a tungsten filament.…”

“…16,17 Alternatively, incorporating carboxylate ligands in uranyl coordination polymers can produce an array of stable radical species upon ionizing radiation and efficiently quench the UO 2 2+ emission in a dose-dependent manner, making them suitable for ionizing radiation dosimetry. [18][19][20][21][22] Despite the emergence of such materials, the rationale of using uranyl cations as a building block of radiation detection materials requires further elucidation. The governing factors of the sensing efficacy, e.g., sensitivity or limit of detection (LOD), remain uncertain and obtaining radiation detecting materials based on uranyl bearing materials is usually accomplished in trial-and-error methodologies.…”

Constructing the Hessian matrix (HM) for large molecules demands huge computational resources. Here, we report a cluster-in-cluster (CIC) procedure for efficiently evaluating HM and dipole derivatives for large molecular clusters by employing the second-order Møller−Plesset perturbation (MP2) theory. The highlight of the proposal is the separation of the estimations of Hartree−Fock (HF) and post-HF components. The parent cluster with n molecules is divided (virtually) into n subclusters centering each monomer and accommodating its near neighbors decided by a distance cutoff. The HF-level HM is obtained by doing full calculation (FC), while the correlation part is approximated by the respective subclusters. A software automating the procedure [followed by calculating infrared (IR) frequencies and intensities] is applied to deduce the IR spectrum for a variety of molecular clusters, particularly water clusters of various sizes, containing up to ∼2000 basis functions. The accuracy of the IR spectrum constructed using CIC is remarkable, with a substantial time advantage (with respect to its FC counterpart). The reduced computational resources and the tractability of the computations are other major benefits of the procedure.

Passive dosimeters enabling accurate measurement of doses from gamma rays to visible light are necessary to ensure efficient utilization of electromagnetic radiation in numerous fields like medical diagnostics and industrial manufacturing. The specific requirements for dosimeters in terms of dosimetry range, sensitivity, accuracy, and stability for each application have led to the development of various dosimeters based on new materials and new mechanisms. Here, a comprehensive review of different types of dosimeters classified according to the response signal, namely electron paramagnetic resonance, electrical, and optical, is provided. This review starts with a general introduction to dosimetry, a classification of dosimeters, and an elucidation of the necessity of dosimeters in various ranges of the electromagnetic spectrum. This is followed by an overview of the fundamental requirements of dosimeters, an explanation of the general dosimetry procedure, and the dosimetric quantities. Emphasis is given to the working mechanism, the design concept, and applications of each type of dosimeter as well as their respective strengths and drawbacks. Challenges and prospects are presented at the end of the review. This review provides an insightful overview of the material‐mechanism‐characteristics‐application relationship of different types of dosimeters that hopefully can serve as inspiration for the development of new devices.
