		Upcoming Research Seminars and Events
Thu, 26 Sep 13 2.00pm – 3.00pm   IMRE, Seminar Room 2	IMRE Seminar on "Spin Transport at the Nanoscale" Spintronics is an emerging field of science and technology that utilizes the electron spin for significantly enhanced or fundamentally new device functionality. After the discovery of the giant magneto resistance effect more than a decade ago, this field has witnessed a significant revolution, encompassing new materials and new physical phenomena.  In recent years, devices that exploit hot electron transport have become increasingly popular as the spin valve transistor, the magnetic tunnel transistor, spin-transfer torque devices, Si spin injection devices, graphene based optoelectronic devices, manganite hot electron transistors etc. In this talk, I will discuss the application of the Ballistic Electron Magnetic Microscopy (BEMM) to probe (sub-surface) charge/spin transport and local magnetic switching in novel magnetic heterostructures and at an energy regime where non-equilibrium processes, relevant for the operation of such devices, are prevalent.   Speaker : Prof Tamalika Banerjee Host: Dr. Thamankar Ramesh Mohan (AC)   (Click here for more information and registration)
Fri, 4 Oct 13 2.30pm – 3.30pm   IMRE, Seminar Room 2	IMRE Seminar on "Macroscopic Assemblies of Nanoscale Building Blocks and their Applications" The huge diversity of hierarchical micro-/nano- rigid structures existing in biological systems is increasingly becoming a source of inspiration of materials scientists and engineers to create next generation advanced functional materials. In this lecture, I will report several facile synthetic protocols for one-pot controlled synthesis of several kinds of unique nanoscale building blocks, which include ultrathin nanowires, nanoplates, and magnetic nanoparticles, conducting nanocables, and carbon-based nanostructures. Then, we discuss how to assemble these nanoscale building blocks into 2D ordered assemblies, 3D macroscopic assemblies, and their functionalities.     Speaker : Prof Shu-Hong Yu Host:  Dr Zong Yun (SI)   (Click here for more information and registration)
Tue, 22 Oct 13 10.00am - 11.00am   IMRE, Seminar Room 2	IMRE Seminar on "Biomaterials for Regenerative Medicine" As stem cell based therapies rapidly advance towards clinical applications, there is a requirement for cheap, easily manufactured, injectable materials that can be tailored to carry stem cells and impart function to such cells. We have recently developed a number of multicomponent hydrogel systems that, by way of their composition and gelation behavior, provide significant flexibility in terms of their mechanical property slates, their biofunctionality and their utility as injectable materials. Firstly, I will describe a new gel platform made from a hydroxyphenol (HP) functionalised, highly branched poly(ethylene glycol) (PEG), with or without hyaluronic acid (HA), via an enzyme mediated, oxidative crosslinking method. Secondly, I will describe a α-CD/pluronic polyrotaxane functionalised hydrogel system with highly tunable mechanical properties (from 3 kPa to 7 MPa!!) and gelation kinetics (from a few seconds to a few hours), presenting data to confirm the mechanism of gelation and its ability to ‘self-heal’ post fracture.   Speaker : Prof Justin COOPER-WHITE Host:   Dr Loh Xian Jun (SI)   (Click here for more information and registration)
Wed, 6 Nov 13 10.00am - 11.00am   IMRE, Seminar Room 2	IMRE Seminar on “One- and Two- Dimensional NMR Experiments in the Solid State for Assignment and Structure” The enormous success of solution state NMR in deciphering structures of molecules of chemical and biological interest has been largely due to experiments that could map proximities of atoms both through scalar and dipolar couplings. Similar approaches to study molecular structures in solids have been evolving and in recent years significant advances have been made for the case of several partially ordered and fully rigid systems.   Speaker : Prof K.V.Ramanathan Host : Dr Pallathadka, Pramoda Kumari (AC)   (Click here for more information and registration)
13 Nov 13 10.00am - 11.00am   IMRE, Seminar Room 2	IMRE Seminar on "Multi-Functionality of Reinforced Polymers and Composite Structures" Multi-functionality is the combination of different properties in one material so as to make it suitable for the use in applications in which different loading conditions must be sustained. Besides the mechanical load bearing capacity, other properties such as thermal stability, electrical conductivity or wear resistance can be of importance. In many cases, polymer based composites are the material of choice, since they can combine the intrinsic properties of the polymers (like light weight, corrosion resistance or toughness) with the unique properties of their reinforcements (such as electrical conductivity, wear resistance, or high mechanical stiffness and strength)   Speaker : Prof Klaus Friedrich Host: Dr He Chaobin(SI)   (Click here for more information and registration)
Tue, 19 Nov 13 2.30pm - 3.30pm   IMRE, Seminar Room 2	IMRE Seminar on "Band Offsets and Semiconductor Devices" In this talk, Prof Robertson will explain the calculation of band offsets between various semiconductors, and between semiconductors and oxides, which involves the metal induced gap state (MIGS) model plus interface dipoles.   Speaker : Prof John Robertson Host: Dr Wang Shijie (DG)   (Click here for more information and registration)
