Absorbed doses for patients undergoing panoramic radiography, cephalometric radiography and CBCT

open access: yesInternational Journal of Occupational Medicine and Environmental Health, 2017
Objectives: Contemporary dental radiology offers a wide spectrum of imaging methods but it also contributes to an increase in the participation of dental radiological diagnosis in the patient’s exposure to ionizing radiation.

Reversible Dual‐Mode X‐Ray Memory Imaging of Photochromic Zero‐Dimensional Halide Perovskite Glass

open access: yesInformation &Functional Materials, EarlyView.
A photochromic halide perovskite glass with embedded Cs4PbBr6 nanocrystals enables reversible X‐ray–induced coloration and luminescence modulation, realizing dual‐mode X‐ray memory imaging with visual and photoluminescent readout. ABSTRACT Integrating photochromic and photoluminescence (PL) properties of halide perovskite glasses enables reversible ...

Ambient‐Light‐Activated Rewritable Optical Patterning in Transparent Long‐Afterglow Garnet Ceramics

open access: yesLaser &Photonics Reviews, EarlyView.
This work demonstrates sunlight‐activated rewritable optical information storage in transparent long‐afterglow Y3Al2Ga3O12:Ce (YAGG:Ce) garnet ceramics fabricated via solid‐state sintering with tetraethyl orthosilicate (TEOS) as a sintering aid. By integrating ambient‐light operability, reversibility, and high optical clarity in a robust ceramic host ...

One‐year follow‐up after fractionated ultra‐high‐dose‐rate FLASH radiotherapy in patient with extramammary Paget disease of the scrotum

open access: yesPrecision Radiation Oncology, EarlyView.
An elderly male patient with extramammary Paget disease of the scrotum and multiple metastases was treated with fractionated FLASH‐RT (40 Gy in 5 fractions) in the scrotal lesion. Abstract Objective Ultrahigh‐dose‐rate radiotherapy (FLASH‐RT) has been shown to reduce radiation‐induced normal tissue injury in preclinical studies.

Synthesis of Samarium‐incorporated X‐ray‐sensitive nanoparticles and hydrogels: Diverse applications in radiation monitoring and dynamic information display

open access: yesSmart Molecules, EarlyView.
Sm3+‐doped α‐NaLuF4 and β‐NaLuF4 were synthesized. The X‐ray‐activated persistent luminescence abilities and afterglow properties can be well controlled. Sm3+‐doped β‐NaLuF4 exhibits remarkable afterglow ability. The hexagonal β‐NaLuF4:3%Sm3+‐incorporated hydrogel can be further programmed with other types of hydrogels to enable tunable emission ...

Thermoluminescence of Uranyl Salts Under Mechano-destruction

open access: yes, 2015
The thermoluminescence of the salts UO2(NO3)2·6H2O and UO2(ClO4)2·6H2O that have been previously treated mechanically at 77K was studied. A maximum was observed in thermoluminescence curve at 80-90K.

A reappraisal of the Middle to Later Stone Age prehistory of Morocco Réévaluer la préhistoire du Maroc, du Middle Stone Age au Later Stone Age

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
Over the last 25 years, perceptions of the early prehistory of Northwest Africa have undergone radical changes due to new fieldwork projects and a corresponding growth in scientific interest in the region. Much of this work has been focused in Morocco, known for its extremely rich fossil and archaeological records in caves and rock shelters.

Thermoluminescence signal in K-feldspar grains: Revisited

open access: yes, 2015
Recent work has shown that infrared stimulated luminescence (IRSL) signals in sedimentary coarse-grain K-feldspars are derived mainly from high temperature thermoluminescence (TL) peaks around 400 degrees C, and the fading components of the IRSL signal ...

And then there was us Et puis nous sommes apparus

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
In 1987, the academic conference ‘Origins and Dispersals of Modern Humans: Behavioural and Biological Perspectives’ was held in Cambridge, UK. Subsequently referred to as the ‘Human Revolution’ conference, this meeting brought together the most prominent academics working in the field of human origins, including archaeologists and palaeoanthropologists,
