Stabilization of aqueous suspensions graphene single sheets by single-stranded DNA is demonstrated using a range physical methods. The negatively charged bio-functionalized are spontaneously assembled into layered hybrid nanocomposites containing intercalated molecules, or co-intercalated mixtures and the redox protein, cytochrome c. Small-molecule reducing agents readily access proteins.
Historical mining of uranium mineral veins within Cornwall, England, has resulted in a significant amount legacy radiological contamination spread across numerous long disused sites. Factors including the poorly documented and aged condition these sites as well highly localised nature radioactivity limit success traditional survey methods. A newly developed terrain-independent unmanned aerial system [UAS] carrying an integrated gamma radiation mapping unit was used for characterisation...
Nuclear power and associated activities are never far from scrutiny, the apparent advantages of technology juxtaposed by risk incidents perceived as being catastrophic. If a major nuclear incident was to occur, an important aspect response management any radionuclide release would be need rapidly establish spatial distributions quantities these released radionuclides, their type in addition corresponding activity. The data received surveys directly inform evacuation plans, on-site strategies...
On the 12th of March 2011, The Great Tōhoku Earthquake occurred 70 km off eastern coast Japan, generating a large 14 m high tsunami. ensuing catalogue events over succeeding 12 d resulted in release considerable quantities radioactive material into environment. Important to large-scale remediation affected areas is accurate and spatial resolution characterisation contamination, including verification decontaminated areas. To enable this, low altitude unmanned aerial vehicle equipped with...
Following the events of March 2011 at Fukushima Daiichi Nuclear Power Plant, significant quantities radioactive material were released into local and wider global environment. At five years since incident, much expense is being currently devoted to remediation a large portion eastern Japan contaminated primarily by radiocesium, yet further expenditure will be required over succeeding decades complete this clean-up. People displaced from their homes incident are now increasingly keen return,...
Since its inception in 1986, the field of atomic force microscopy (AFM) has enabled surface analysis and characterisation with unparalleled resolution a wide variety environments. However, technique is limited by very low sample throughput temporal making it impractical for materials science research on macro sized or time evolving samples such as observation corrosion. The potential AFM sparked intense efforts to overcome these limitations shortly after invention, led development high-speed...
This work has investigated the influence of common groundwater anions (Cl−, NO3−, SO42− and HCO3−) on corrosion behaviour associated removal copper (Cu) zinc (Zn) ions onto nanoscale zero-valent iron particles (nZVI). After 16 week exposure to solutions containing each anion at 10 mM concentrations, nZVI was observed corrode into different (hydr)oxide phases (determined using XRD), depending upon present: HNO3− produced goethite particles; NO3− predominantly magnetite/maghemite both Cl− a...
In response to the Fukushima Daiichi Nuclear Power Plant accident, there has occurred unabated growth in number of airborne platforms developed perform radiation mapping—each utilising various designs a low-altitude uncrewed aerial vehicle. Alongside associated advancements system transporting detection payload, from earliest radiological analyses performed using gas-filled Geiger-Muller tube detectors, modern and mapping are now based near-exclusively on solid-state scintillator detectors....
