Ramphal Lecture Theatre, University of Warwick
In 1959 Richard Feynman gave a remarkably prescient and now-famous talk titled "There's Plenty of Room at the Bottom" in which he spoke of the possibilities afforded by extreme miniaturization. In that talk he discussed a "great future" in which "we can arrange the atoms the way we want." Thirty years later, in 1989, we had the good fortune to achieve that milestone. Feynman's "great future" was ushered in with the discovery of ways to manipulate individual atoms using a scanning tunneling microscope. My dual goals in this presentation are to relate a story of discovery -- how we learned to manipulate atoms – and to share with you some sense of the excitement, humor and joy we found in the journey.
All welcome, no registration necessary.
Thursday July 27th, University of Warwick
This symposium aims at bringing together leading international and UK experts in an unformal and stimulating environment to present recent advances in the field and encourage interdisciplinary discussion and collaborations. Early career researchers will be given the unique opportunity to showcase their research and to directly interact with international experts.
The Faculty of Science at the University of Warwick would like to invite you to join us for an Industry Day where the Physical Science Departments (Physics, Chemistry, Engineering and WMG) will showcase the research capability that the Faculty is eager to direct towards the research development and productivity challenges faced by industry.
Professor Julie Kornfield (Caltech), Multiplicity of Morphologies in Poly (L-lactide) Bioresorbable Vascular Scaffolds
Friday 21 April 11-12, IMC002
Poly(L-lactide), PLLA, is the structural material of the first clinically approved bioresorbable vascular scaffold (BVS), a promising alternative to permanent metal stents for treatment of coronary heart disease. BVSs are transient implants that support the occluded artery for 6 months, and are completely resorbed in 2 years. Clinical trials of BVSs report restoration of arterial vasomotion and elimination of serious complications such as Late Stent Thrombosis. It is remarkable that a scaffold made from PLLA, known as a brittle polymer, does not fracture when crimped onto a balloon catheter or during deployment in the artery. We used x-ray microdiffraction to discover how PLLA acquired ductile character and found that the crimping process creates localized regions of extreme anisotropy; PLLA chains in the scaffold change orientation from the hoop direction to the radial direction on micron-scale distances. This multiplicity of morphologies in the crimped scaffold works in tandem to enable a low-stress response during deployment, which avoids fracture of the PLLA hoops and leaves them with the strength needed to support the artery. Thus, the transformations of the semicrystalline PLLA microstructure during crimping explain the unexpected strength and ductility of the current BVS and point the way to thinner resorbable scaffolds in the future.
The Materials GRP is supporting a number of collaborations across departments in Warwick through the award of Summer Placement Bursaries. A key criteria is that two supervisors are named from two different departments. Collaborations will take place during Summer 2017. Preference will be given to new collaborations. Bursaries will be up to a maximum of £2000.
The deadline for applications will be noon on 24th March 2017 and awards will announced by March 30th 2017.
The Royal Society of Chemistry Biomaterials Awards Symposium will be taking place at the University of Warwick on Friday 3rd March 2017.
