Session 140 Autumn Schedule
Talks will take place on Tuesdays in the Ramsay Lecture Theatre and will start at 6.15pm. Pre- and post-talk receptions will be in the Nyholm Room as usual, but will start at 5.45pm and 7.15pm respectively.
Atomic Fluorescence Spectroscopy - Analytical Curiosity or Useful Tool?
Dr Bin Chen
Tuesday 20 October 2015
Atomic Fluorescence Spectrometry (AFS) is an ideal detection technique for speciation studies concerning hydride forming elements – mainly As, Se and Sb and Hg. The analytical features of AFS, such as detection limits below the µg/L and the wide linear calibration range, up to the mg/L, allow its application to a great variety of environmental, biological and food samples.
AFS represents a suitable alternative to other atomic spectrometers commonly employed in speciation studies such as Atomic Absorption Spectrometry (AAS) and Inductively Coupled Plasma-Mass Spectrometry (ICPMS). This talk will explain the instrumental couplings of chromatographic (HPLC and GC) with AFS detection, with online hydride generation for the speciation of inorganic and organic compounds of As, Se and Sb, and cold vapour for Hg.
Other optional intermediate steps are online photo-oxidation (UV), pyrolysis for non-directly reducible compounds. Many different sample types (e.g. water, soils, air, biota, food) have been analysed using these instrumental couplings with AFS detection.
Why does the same wine taste different?
Tuesday 27 October 2015
Have you ever been drinking wine that you love and others hate? Why might you prefer Prosecco to Champagne? How come that expensive Claret tastes to you like cheap Rioja?
In this lecture will we learn why people have different wine experiences, and we will delve into the areas of sensory science and human physiology. Learn all about genotypes, hypertasters, ageusia, specific anosmia and lingual acuity to find out why your sensory system might be as unique as your fingerprint.
Tony Milanowski in the course leader for the honours degree in viticulture (grapegrowing) and oenology (winemaking) at Plumpton College, which is home to the UK wine research centre. Born and trained in Australia, Tony has worked in wineries big and small, and made all styles of wine from those supermarket wines enjoyed by many people premium wines found on the wine list of many of the world’s great restaurants. Having made wine in Australia and Italy for over 10 years, Tony is now based in Sussex. At Plumpton College he lectures in Winemaking and it’s related sciences, to students who dream of becoming the next generation of winemakers. Tony has passion for Coonawarra Cabernet, Italian Grillo and English Sparkling wine and loves to teach about fermentation and what makes those wines so special.

Solid State Memory
The Challenges to Silicon
Tuesday 17 November 2015
The transition from rotating electronic memory media to solid state silicon memory is now well advanced. Even as that happens silicon itself continues to be challenged for its nanometre size memory crown.
Ron Neale with a 50 year experience as a researcher, developer, writer, outspoken critic and the holder of more than 10 patents in the area of solid state memory will explore the materials, mechanisms and the various levels of success of the many challengers.
Where changes in phase, structural and electrochemical changes, quantum effects and artificial materials are used to produce the two or many data states required for the atomic sized cells in the memory arrays of the future. The presentation will give those attending a guide to what it will take for the challengers to succeed and the timing.
Automated Tracking and Precision Observation from Space
Andrew Margetts Kelly
Tuesday 24 November 2015
From tracking aeroplanes to feeding the world; what are spacecraft useful for anyway? An insight into the emerging and future potential of primary, secondary and passive techniques utilised by satellites for applications ranging from the live tracking of ships, submarines and aircraft… to precision farming and disaster relief. How low-cost synthetic aperture radars, high resolution hyperspectral optical instruments and the emerging developments in GNSS reflectometry feature in complementing and advancing the existing spaceborne capability.
Tuesday 1 December 2015
Last year was the first time that UK Higher Education Institutions were required to submit 'impact case studies’ as part of their assessment - that is, to report on the non-academic outputs of their research for the 2014 Research Excellence Framework (REF). The team at the Policy Institute at King’s College London were commissioned by the Higher Education Funding Council for England (HEFCE) to analyse the 6679 non-redacted impact case studies that were submitted and completed their report in March 2015. In this session, Dr Saba Hinrichs-Krapels, will present some of the findings from this study. The analysis of the case studies used text mining techniques leading to the identification of 60 impact topics or areas where research influences society, such as medical ethics, climate change, clinical guidance and women, gender and minorities. Automated text mining was supplemented with ‘deep mines’, where more than 1000 case studies were read to provide a deeper picture of the data – looking at specific questions such as ‘what is the impact and value of research on clinical practice and health gain?’ and ‘what has been the impact of research on BRIC countries?’. These case studies are now available to read online in a searchable database developed by Digital Science, providing a rich resource that has enabled us to demonstrate that UK research has thousands of different applications worldwide.
