Functionalized paramagnetic nanoparticles for waste water treatment (2010)
Journal Article
Elder, G. R., Duffield, J. R., Urban, I., Ratcliffe, N. M., Duffield, J., Elder, G., & Patton, D. (2010). Functionalized paramagnetic nanoparticles for waste water treatment. Chemical Communications, 46(25), 4583-4585. https://doi.org/10.1039/b925933c

An approach to the design, development and implementation of a new separation technology for use in the decontamination of radioactive waste streams is reported here. Calixarene-crown-6 derivatives with terminal carboxyl groups were synthesised and a... Read More about Functionalized paramagnetic nanoparticles for waste water treatment.

Investigation of the semiochemicals of confused flour beetle Tribolium confusum Jaquelin du Val and grain weevil Sitophilus granarius (L.) in stored wheat grain and flour (2010)
Presentation / Conference
Abuelnnor, N., Jones, P., Ratcliffe, N. M., de Lacy Costello, B., & Spencer-Phillips, P. T. (2010, June). Investigation of the semiochemicals of confused flour beetle Tribolium confusum Jaquelin du Val and grain weevil Sitophilus granarius (L.) in stored wheat grain and flour. Paper presented at 10th International Working Conference on Stored Product Protection

This investigation sets out to identify specific volatile compounds from both flour infested with the confused flour beetle, Tribolium confusum and wheat grain infested with the grain weevil, Sitophilus granarius. These volatiles could help to aid th...

Gas sensor (2010)
Patent
Ratcliffe, N. M., de Lacy Costello, B., & Richards, W. (2010). Gas sensor. EP20080804338

A method of detection of a volatile compound in a gaseous atmosphere comprises irradiating a semiconducting metal oxide material with ultraviolet light, exposing the irradiated material to the gaseous atmosphere and determining the presence of any vo... Read More about Gas sensor.

W1908 diagnostic potential of volatile organic compounds in inflammatory bowel disease (2010)
Journal Article
Ahmed, I., Probert, C., Ratcliffe, N. M., & Greenwood, R. (2010). W1908 diagnostic potential of volatile organic compounds in inflammatory bowel disease

Introduction: Crohn's disease (CD) and ulcerative colitis (UC) are diagnosed using invasive investigations which patients find unpleasant. Non-invasive modalities to asses the clinical course of the disease are yet to be adopted. Volatile organic com...

Application of Similarity Coefficients to Predict Disease Using Volatile Organic Compounds (2010)
Journal Article
Probert, C. S., Smith, S., White, P., Redding, J., Ratcliffe, N. M., & Probert, C. S. (2010). Application of Similarity Coefficients to Predict Disease Using Volatile Organic Compounds. IEEE Sensors Journal, 10(1), 92-96. https://doi.org/10.1109/JSEN.2009.2035771

Measures of similarity are used to provide evidence in support of the conjecture that the presence and absence profile of a subset of volatile organic compounds found in urine differ between healthy (non-prostate cancer) male donors and prostate canc...
