Defect‐Templated Phase Engineering in Atomically Thin Metals

Advanced Materials, EarlyView.
Graphene defects are transformed from passive imperfections into programmable templates for phase‐selective growth of atomically thin silver. Plasma‐generated boundary defects favor Ag(1), whereas sp3‐rich zero‐layer graphene promotes Ag(2). This defect‐directed intercalation links local graphene chemistry to crystalline phase, electronic structure ...

Ion Concentration and Voltage Imaging With Fluorescent Nanodiamonds

Advanced Materials, EarlyView.
We demonstrate reversible switching between the fluorescent NV0 and the dark NV+ state, in sub‐30 nm FNDs via surface oxidation and hydrogenation, respectively. In an electrochemical cell, we show that the fluorescence from hydrogenated particles enables all‐optical imaging of voltages and ion concentrations at the micrometer scale.

All‐Amyloid Functional Coacervates

Advanced Materials, EarlyView.
This study introduces an all‐amyloid interfacial complex coacervate technique that employs charge‐mediated or functionalization‐assisted complexation of oppositely charged food protein‐derived amyloid nanofibrils to engineer functional soft constructs across multiple length scales.

Side‐Chain‐Induced Interlayer Slipping in Metalloporphyrin COFs Enables Microenvironment and Spin‐State Regulation for Photocatalytic CO2 Reduction

Advanced Materials, EarlyView.
Alkoxy chain length drives a continuous transition from eclipsed AA to a serrated, slipped AA* configuration over Co‐porphyrin COFs. A moderate slip both contracts the pore channel to enrich CO2 and suppress hydrogen evolution, and enhances collective high‐spin of Co sites, which delivers a record CO production rate with high selectivity.

Ionising radiation in the workplace

BMJ, 2015
Low risk but not no risk Information on radiation risk for cancer has come from several sources,1 in particular the Japanese atomic bomb survivors that comprise the Life Span Study cohort.2 It remains a controversial question whether there is a risk at low doses and low dose rates; although some have suggested the existence of thresholds below which ...

TREATMENT OF THYROTOXICOSIS WITH IONISING RADIATION

The Lancet, 1968
Abstract Because of the disadvantages of conventional treatment of thyrotoxicosis with 131 I, two alternative methods of radiation therapy were assessed. One group of patients received a dose of 131 I calculated to deliver 2400 rads to the thyroid, and a second group was treated by external radiation from a 60 Co source, with doses of 115-900 rads.

Dosimetry of ionising radiation in modern radiation oncology

Physics in Medicine and Biology, 2016
Dosimetry of ionising radiation is a well-established and mature branch of physical sciences with many applications in medicine and biology. In particular radiotherapy relies on dosimetry for optimisation of cancer treatment and avoidance of severe toxicity for patients.

Ionising radiation in nanotechnology

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2005
The ability to fabricate structures with nanometric precision is of fundamental importance to any exploitation of nanotechnology. The fabrication of the required geometric structures is a key for further technology development. Therefore, we have concentrated on the elaboration of the methods for manufacturing nanostructure coated fibers and nanotubes ...
