Title of talk: Pursuit of Record Breaking Energy Barriers in Molecular Nano-Magnets
Speaker's name: Prof. Muralee Murugesu
Speaker's organisation: University of Ottawa
Talk abstract: Multimetallic rare-earth systems and especially DyIII, ErIII-based materials have sparked much interest in the area of molecular magnetism due to the large intrinsic magnetic anisotropy of the lanthanide ions. When such a unique property is combined with a high- spin ground state (S) in a molecular complex, it causes slow relaxation of the magnetization as seen for Single-Molecule Magnets (SMMs). Lanthanide only SMMs are rare due to the difficulty in promoting the magnetic interactions via the overlapping bridging ligand orbitals with the contracted 4f orbital of the ions. Toward the goal of inducing significant magnetic interaction between lanthanide ions and subsequently isolating high-energy barrier SMMs, our research is currently focused on the use of phenoxide bridges as superexchange pathways between spin carriers. In addition, organometallic lanthanide sandwich complexes provided an alternative approach for understanding intriguing quantum mechanical properties of SMMs.

Title of talk: Is Area-wide Pest Management Useful? The Case of Citrus Greening
Speaker's name: Associate Professor Ariel Singerman
Speaker's organisation: University of Florida
Talk abstract: Citrus greening or Huanglongbing (HLB) currently poses a severe threat to citrus production worldwide. No treatment or management strategy is yet available to cure the disease. While working on developing short- and long-term treatments, scientists recommend controlling the vector of the disease, and area-wide pest management has been proposed as a superior alternative to individual pest management. We analyzed a unique data set of farm-level citrus yields in Florida that allowed us to test the hypothesis. We found that yields of blocks located in an area with higher participation in coordinated sprays were 28%, 73% and 98% higher in 2012/13, 2013/14, and 2014/15, respectively, compared to the yields of blocks under the same management but located in an area with lower participation; providing evidence on the efficiency of a well-performing pest management area to deal with HLB. In addition, we present survey data that provide insights about producers' behavior and attitudes toward the area-wide pest management program. Despite the relatively high economic benefit we found area-wide pest management can provide, the strategic uncertainty involved in relying on neighbors seems to impose too high of a cost for most growers, who end up not coordinating sprays.

Location: AIBN Seminar Room (Building 75 Level 1)

Title of talk: LIGHT STIMULATED INTERACTIONS IN ORGANIC/INORGANIC HYBRIDS FOR SENSING AND CELL STIMULATIONS
Speaker's name: Dr. H.C. Helmuth Moehwald
Speaker's organisation: Max-Planck-Institute of Colloids and Interfaces, Potsdam
Talk abstract: There have been many developments to fabricate ultrathin polymeric films, but less is known about the interaction of these films with an inorganic particles and support. I will discuss 3 different systems, where the interaction is most important for the function of the film in response to processes on the support.
1. Inserting metallic nanoparticles into a polymeric capsule shell on locally heat the shell and thus release a drug. This can be used for local drug delivery to follow cellular functions (R.Palakar,A.G.Skirtach,O.Kreft,M.Bedard,M.Garstka,K.Gould,H.M.,G.B.Sukhorukov,M.Winterhalter,S.Springer, Small,5 (2009)2168 )
2. In cooperation with G. Zhang, Jilin University, a nanoplasmonic surface with a Ag film deposited is designed that is optically transparent and that can be excited by visible light. Field enhancement can lead to enhanced optical or Raman spectroscopic sensing. We introduce a new technique, skiving, to prepare 1D,2D and 3D gaps with nm precision and demonstrate their enhanced optical properties. (Z.Zhou,Z.Y.Zhao,Y.Yu,B.Ai,H.M.,R.C.Chiechi,J.K.W.Wang,G.Zhang, Adv.Mater.28 (2016) 2956 )
3. A TiO2 support excited by UV light, sonochemically treated also by visible light, ejects charge carriers, that can be converted into protons in an aqueous or polyelectrolyte environment. The resulting pH change can lead to a change in thickness and elasticity of the polymeric film. This can lead to changes in cell growth and via light this can be guided on a surface. (S. A.
