New paradigms in the research and development of multifunctional oxides and nanocarbon thin films are providing the bases for new physics, materials science, chemistry, and biological processes, impacting a new generation of high-tech diamond based high-power electronics and multifunctional biomedical devices.
This talk will focus on discussing the science and technology of transformational piezoelectric, super high-dielectric constant (k ≥1000) films, and super-paramagnetic oxide nanoparticles, and a new paradigm material named ultrananocrystalline diamond (UNCDTM) in thin film form, and their integration to produce a new generations of high-tech diamond high-power electronics, and external and implantable medical devices, as described below:
1)    Fundamental and applied materials science and technological development of transformational TiOx/Al2O3 nanolaminates, exhibiting giant dielectric constant (k≥1000), low leakage current (10 -8–10 -9 A/cm2, and low losses (tan  = 0.04); this part of the talk will include a brief discussion of the physics responsible for the giant dielectric constant;
2)    Fundamental and applied materials science and technological development of the process to integrate the high-K dielectric nanolaminates on single crystal diamond to fabricate first diamond-based transistors involving integrated TiO2/ Al2O3 nano-laminates/single crystal diamond, 
3)    UNCD films co-developed and patented by O. Auciello and colleagues are synthesized by novel microwave plasma chemical vapor deposition and hot filament chemical vapor deposition techniques using a patented Ar-rich/CH4 chemistry that produces diamond films with the smallest gran size demonstrated today (2-5 nm). The fundamental science underlying the synthesis and properties of the UNCD films and applications to devices will be discussed. The UNCD films exhibit the lowest friction coefficient (0.02-0.04) compared with metals (≥ 0.5) currently used in many prostheses (e.g., hips, knees), electrically conductive UNCD coatings with nitrogen in grain boundaries can enable a new generation of neural electrodes, UNCD coatings are extremely biocompatible, and have been demonstrated to provide superior scaffolds for embryonic cell growth and differentiation. Original Biomedical Implants (OBI-USA) and OBI-México, founded by Auciello and colleagues, are developing new generations of high-tech diamond-based electronics and implantable medical devices based on multifunctional/biocompatible UNCD coatings, described in order of less to highest development until now, namely: a) Brain neurons functionalized UNCD-coated polymer with tailored stiffness, enabling next generation less invasive electrodes for neural stimulation; b)  UNCD-based MEMS cantilevers powered by biting heart cells to power new generation  defibrillator/pacemaker, eliminating battery power; c) new generation of Li-ion batteries with ≥ 10x longer life and safer, using LIBs electrodes coated with Li-corrosion resistant electrically conductive N-atoms/grina boundaries incorporate N-UNCD films, membranes and inner wall battery case, enabling next generation defibrillator/pacemakers and implantable and external power generation devices with order of magnitude longer battery powered life and safer; d) new generation of implantable prostheses (e.g., dental implants (in clinical trials in humans-7 patients received UNCD-coated DI in a dedicated clinic in México), hips, knees, stents and more) coated with UNCD, eliminating failure of current metal-based implants due to synergistic mechanical wear or blood interaction / chemical corrosion by body fluids; e) Integrated UNCD-coated magnet outside the eye, creating magnetic field to attract biocompatible superparamagnetic  FeO2 nanoparticles injected inside the eye to push detached retina to place, enabling revolutionary retina reattachment (clinical trials in humans in progress); f) A key medical device where UNCD coating has made an impact is a UNCD-coated silicon based microchip implantable inside the eye as a key component of the artificial retina to return partial vision to people blinded by genetically-induced degeneration of photoreceptors (a device named Argus II is currently in the market by Second Sight, returning partial vision to people blinded by retinitis pigmentosa).
