Carbo-Iron® is an applied composite material consisting of colloidal activated carbon and embedded nanoscale zero valent iron (ZVI). In a recent long term study of a field site in Germany, it was injected into an aquifer contaminated with tetrachloroethene (PCE). Carbo-Iron® particles accumulated the pollutants and promoted their reductive dechlorination via a combination of chemical and microbial degradation processes. The presence of the dominant degradation … Continue reading Microbes and nanomaterials working in harmony for contaminated land remediation – application of Carbo-Iron® at a contaminated field site
Copper nanoparticles play an important role in the pharmaceutical industry, acting as catalysts in the synthesis of organic building blocks for a range of pharmaceutical compounds through ‘click’ chemistry’ reactions. However, there is a growing need to develop sustainable, affordable and green synthesis procedures for these important nanomaterials. Our new work, published in Small, demonstrates a novel, environmentally friendly biotechnological method for synthesising copper nanoparticles … Continue reading Metal-reducing bacteria offer a greener route for producing copper catalysts
The International Society of Subsurface Microbiology (ISSM) 2017 was held in Rotorua, New Zealand. Our very own Dr Laura Newsome attended the conference as an ambassador for the European Association of Geochemistry (EAG). Here is a link to a conference review she has written for the EAG Blog: http://blog.eag.eu.com/general/rotorua-bubbles-with-microbiologists/ Continue reading Rotorua bubbles with microbiologists: An EAG Ambassador at ISSM 2017
As part of the Next Generation Nuclear (NGN) CDT, I completed a 3 month taught course as part of my training with the aim to give me an overview of the nuclear industry. Each week was dedicated to a different area, ranging from structural engineering to high level decision making. We also had the opportunity to visit key nuclear sites around the UK, and gain … Continue reading NGN CDT Taught Course
The consumption of arsenic in waters collected from tube wells threatens the lives of millions worldwide and is particularly acute in the floodplains and deltas of southern Asia. The cause of arsenic mobilization from natural sediments within these aquifers to groundwater is complex, with recent studies suggesting that sediment-dwelling microorganisms may be the cause. In the absence of oxygen at depth, specialist bacteria are thought … Continue reading What is happening? Who to blame? Bacterial community structure in two arsenic impacted aquifers!
Last November several members of the Geomicrobiology group were allocated talks at the Royal Society of Chemistry’s Radiochemistry Group Young Researchers Meeting, held at the School of Earth and Environment in the University of Leeds. This is a biennial conference, which allows young scientists (under 35) to meet and present their work in radiochemistry to their contemporaries in an informal and friendly atmosphere. Thanks to … Continue reading RSC Radiochemistry Group Young Researchers Meeting
Hello, my name is Dawn Melisa, but most people in this department just call me Dawn. I am originally from a very small island in the Caribbean called Anguilla, it is so small that it is often shown as a dot on most maps. I completed my undergraduate degree in Geology at the University of Manchester between 2014 to 2017. In my final year, I … Continue reading New PhD Student: Dawn Buchanan
