"Be Not Afraid", Juana Acrivos

If l asked what am I doing here? the answer should be that I am here to recount the experience of a condensed matter scientist teaching frontier chemical physics at a so called "Undergraduate Institution with ≈47% Minorities" But should one distinguish undergraduate from graduate ability, minority from non-minority ability to do frontier science that shall benefit everyone? I hope to convince you the answer is no; the title of my address was borrowed from Pope John Paul's recent best seller in order to have the courage to do the job. This attitude is probably no different from anyone else …

Dynamic electron spin resonance (ESR) and extended x-ray absorption edge fine structure (XAFS) measurements suggest that layered organic metals and cuprate superconductors behave similarly. The response to microwave radiation in a modulated external magnetic field indicates that: (i) triplet state, T * ESR is observed below Tc for both; (ii) the condensation of free spin doublet D to T* occurs above the transition temperature to superconductivity Tc (10 ± 1 K for the organic metal (BEDT-TTF)3Ta2F11 and 92 to 12 K for YBa2Cu3O7-δ and its rare earth derivatives); (iii) antiferomagnetic (AF) resonance is detected above Tc for the organic metal. …
