Auciello graduated with M.S. (1973) and Ph.D (1976) degrees in Physics from the Physics Institute “Dr. Balseiro” (Universidad Nacional de Cuyo, Argentina). Electronic Engineering at the University of Córdoba-Argentina (1964-1970).
Auciello was Researcher at the University of Toronto-Canada (1979-1984), Associate Professor at North Carolina State University (1985-1988), and Senior Research Scientist at the Microelectronics Center of North Carolina (1988-1996). He was a Senior Scientist at Argonne National Laboratory (1996-2005) and Distinguished Argonne Fellow (2005-2012). He is an Adjunct Professor at University of Colorado-Colorado Springs and Michigan State University.
He is directing basic and applied research programs on different fields, involving multi-component oxide thin films and application to systems and devices (ferroelectric memories, resistive change memories, nanoscale CMOS devices, photovoltaic energy generation / storage devices, high-frequency devices, piezoelectric thin films for MEMS/NEMS sensors and actuators); and nanocarbon thin films (ultrananocrystalline diamond (UNCD) and graphene films) and applications to industrial, electronics, MEMS/NEMS, and implantable medical devices).

The UNCD film technology is now commercialized for industrial components and systems by Advanced Diamond Technologies (ADT), a Company founded by Auciello and Carlisle, spun-off from Argonne in 2003, and by Original Biomedical Implants (OBI), a company founded by Auciello and Gurman (MD), in 2013, for commercializing a new generation of UNCD-coated implantable medical devices and medical treatments based on nanotechnology.
Auciello has edited 20 books on various topics, published about 500 articles in the fields described above, holds 20 patents, and organized, chaired, and lectured at numerous national and international conferences. He is associate editor of Appl. Phys. Lett., Integrated Ferroelectrics, and editor of two book series on thin films and applications to devices (Academic Press). He was member the Materials Research Society (MRS) Board of Directors (2000-2003), Co-Chair MRS International Relations Committee, Vice President of the MRS in 2012, President in 2013, and Past President in 2014.

He has numerous Awards, including seven R&D 100 Awards, 2003 Hispanic Engineering National Achievement Award, 2006 Federation of National Laboratories Award, 2008 University of Chicago Distinguished Performance Award, and is a Fellow of the AAAS and MRS.

ABSTRACT
New paradigms in the research and development of novel multifunctional oxide and nanocarbon thin films are providing the bases for new physics, new materials science and chemistry, and their impact in a new generation of multifunctional devices for micro/nano-electronics and biomedical devices. This talk focus on discussing the science, technology, and engineering of multifunctional oxide and nanocarbon thin films and applications to a new generation of multifunctional micro and nano-devices, as described below:
1.       Science and technology of complex oxide thin films and application to key technologies:
• Novel TiO2/Al2O3 superlattices, exhibiting giant dielectric constant (up to k=1000), low leakage current (10-7-10-9 A/cm2) and low losses (≤ tang d=0.04), based on new physics underlined by the Maxwell-Wagner relaxation mechanism, which enables a new generation of microchip embedded capacitors for microchips implantable in the human body, the next generation of gates for nanoscale CMOS devices, and super-capacitors for energy storage systems.
• Novel BiFeO3/SrTiO3/ BiFeO3 nanolaminates (BSB-NL) have recently been shown to exhibit two orders of magnitude lower leakage current than stochiometric BFO layers, i.e., from 10-5 A/cm2 to 10-7 A/cm2. The BSB-NL also shows very high piezoelectric response, which is ~ 5 times higher than that of the pure BFO with the same thickness. The strained state of the BFO layers concurrently with the chemical and crystallographic state of the interfaces between the BFO and STO layers contribute to the very high values of piezoresponse and very low leakage current observed in the BSB-NLs. BSB-NL are being integrated with the ultrananoacrystalline diamond (UNCD) films described below to develop a new generation of implantable biosensors and piezoelectrically actuated MEMS drug delivery devices.
Science and technology of ultrananocrystalline diamond (UNCD) films and integration for fabrication of a new generation of industrial devices, and high tech and biomedical devices:
R&D of novel multifunctional nanocarbon thin films are providing the bases for new physics, new materials science and chemistry, and their impact in a new generation of multifunctional medical devices. This talk will focus on discussing a new paradigm in multifunctional novel ultrananocrystalline diamond (UNCD) thin films and integration into a new generation of medical devices and implants as described below:
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 an Ar-rich/CH4 chemistry that produces films with 2-5 nm grains, thus the name UNCD to distinguish them from nanocrystalline diamond films with 30-100 nm grains. The fundamental science underlying the synthesis and properties of the UNCD films will be discussed, as well as the integration with other materials for device fabrications. The UNCD films exhibit a unique combination of outstanding mechanical, trtibological, electrical, thermal, and biological properties, which already resulted in industrial components and devices currently commercialized by Advanced Diamond Technologies (a company co-founded by O. Auciello and colleagues in 2003, made profitable in 2014). Devices and systems reviewed include: a) UNCD-coated mechanical pump seals, providing up to 20% energy cost saving via friction reduction, for the petrochemical, pharmaceutical and car industries (shipping to market); b) UNCD-coated bearings for mixers for the pharmaceutical industry (shipping to Merck-Millipore market); c) new electrically conductive UNCD-coated metal electrodes for water purification system, which outperform all other electrodes in the market today (shipping to market); d) UNCD-based MEMS energy harvesting devices, biosensors and drug delivery MEMS devices; e) New generation of Li-ion batteries with ≥ 10x longer life and reduced size, using UNCD-based coatings technology for new anodes, membranes and inner wall battery case chemically resistant coating; f) new generation of medical devices (e.g., artificial retina to restore partial sight to blind people, dental implants, hips, knees, and more) based on biocompatible UNCD coatings.
