 l infections: A junction between material science and biology\nBy Beth T
 rinh\n\nAntibacterial drug resistance is a major global health issue wit
 h dwindling effectiveness of current antibiotics potentially making curr
 ently treatable infections a significant health issue in the future. \nC
 urrent methods of bacterial identification and detection may take up to 
 a week\, and often require specialist knowledge and equipment. This ofte
 n leads to incorrect treatment and the use of \nunneeded antibiotics\, c
 ontributing to antibiotic resistance. There is therefore an urgent need 
 for simple and reliable diagnostics that can quickly determine the prese
 nce of bacterial infections which \nwill allow targeted treatments to be
  prescribed\, thus reducing unnecessary use of antibiotics. There is ong
 oing materials science research using a range of technologies such as na
 noparticles\, \nbiosensors\, fluorescent materials and surface enhanced 
 Raman scattering to develop technologies which provide user friendly\, p
 oint-of-care diagnostics as an initial test of infection. \nThis present
 ation discusses current and future research in the development of new\, 
 novel rapid diagnostic tests. \n\nLead-Induced Stress Corrosion Cracking
  of Alloy 690TT \nBy Giulia Mazzei\n\nStress Corrosion Cracking (SCC) is
  one of the major degradation mechanisms of structural materials employe
 d in nuclear power plants. SCC requires the synergistic effect of stress
  (applied or residual)\, \na corrosive environment\, that is specific fo
 r the material\, and a susceptible microstructure. In pressurized water 
 reactors\, the steam generator is the interface between primary side (pr
 oducing nuclear \nenergy and radioactive) and the secondary side\, which
  is considered a conventional loop subjected to less restrictive control
  on the water chemistry. Although lead is hereby present in concentratio
 ns \nof part per billions\, it tends to build-up due to the presence of 
 occluded regions with low flow and high temperatures\, causing a specifi
 c SCC mechanism (referred as PbSCC). The steam generators \ntubes\, made
  of Ni-based thermally treated Alloy 690\, are particularly prone to cra
 cking in caustic crevice conditions\, with consequences on the operabili
 ty of the plants. In the present study\, Alloy \n690TT has been exposed 
 to caustic solutions at different pH values with 1000 ppm of PbO at 315?
 C using self-loaded C-rings. The baseline microstructure of Alloy 690TT\
 , as well as the deformed \nlayer on the outer surface introduced during
  the manufacture of the tubes\, were microstructurally characterized in 
 order to understand the effect of carbides and the Bielby layer on the m
 aterials \nperformance. The results indicated that the resistance to PbS
 CC was affected by the surface finish (polished and as received conditio
 ns) and showed a threshold trend with the pH. Advanced \nelectron micros
 copy techniques (SEM\, ATEM and FIB) have been used to analyse the oxide
  layer and shed light on the role of Pb on in the SCC crack propagation 
 mechanism. \n\nMetallurgy in the Pre-Columbian Andes \nBy Paul Barron \n
 \nThe civilisations that inhabited the Andean mountain ranges possessed 
 a rich metallurgical tradition that utilised a variety of alloys compris
 ing of copper\, gold\, silver and other metals. \nThe ways that metals w
 ere used in these civilisations demanded smelting\, forging and processi
 ng methods that were unique to this part of the world. This talk will di
 scuss how the usage \nof metal shaped the techniques employed by these c
 ultures while giving some examples in the form of artefacts recovered fr
 om the region. These examples will also explore how we \nknow what we kn
 ow by detailing the scientific techniques used to investigate the artefa
 cts\, as well as a discussion of why the artefacts are important.\n\n\nT
 hin Coatings for Light Alloy Components in the Automotive Industry \nBy 
 Dominic Shore\n\nWeight reduction is an important constraint in automoti
 ve design as it is imperative to maximizing fuel efficiency and vehicle 
 performance. This has driven an increase in the use of \n“light alloys” 
 such as aluminium and magnesium alloys for components. These alloys exhi
 bit low densities and high strength-to-weight ratios. With increasing en
 vironmental legislation \nregarding vehicle efficiency and with the wide
 spread electrification of automotive vehicles on the horizon\, it is env
 isaged that the demand for light alloys in the sector will continue to \
 ngrow in the future. \nWhilst chosen for inherent strength/density prope
 rties\, many aspects of performance are determined by the near surface c
 haracteristics of the material. In this talk I will be \nexploring how t
 hin coating technologies can be applied to light alloy automotive compon
 ents to maximize their suitability and performance with regards to: corr
 osion\, joining\, \nwear\, tribology and aesthetic\, looking at current 
 technologies and coating solutions to long existing challenges.\n\nUnder
 standing the role of zinc in radiation field reduction for light water n
 uclear power plants \nBy Ciara Fox\n\nIn nuclear reactors the exposure o
 f working personnel to radiation is a constant concern and extensive wor
 k has been undertaken to minimise this exposure. In the 20th century \na
  main research focus was the impact of cobalt gamma radiation build-up i
 n Light Water Nuclear Reactors (LWRs). Historically up to 80 % of the ra
 diation field in a LWR could \nbe attributed to cobalt corrosion product
  activation by the core and subsequent deposition on out of core compone
 nts. \n\nIn the 1980s it was noticed that the use of brass condenser pip
 ing led to a reduction in the radiation field caused by cobalt gamma rad
 iation. Subsequent investigation revealed \nthe presence of ionic zinc c
 orrosion products within the coolant water were responsible for the redu
 ced radiation field observed. This talk will explain the role of zinc in
  radiation \nfield reduction and the subsequent development of the zinc 
 injection system.   \n\n\n\n
