Design for AM +ó__ the key to the industrialization of additive manufacturing
2020
UNCD films, developed/patented by Auciello and colleagues,
are grown on many substrates by novel MPCVD and HFCVD
technique, using Ar/CH4 chemistry, producing films with 2-5
nm grains. 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 Nitrogen-
doped N-UNCD coatings enable a new generation of corrosion
resistant electrodes, UNCD coatings are the best biocompatible
material, made of C atoms (element of life in the human DNA,
cells, and molecules). OBI-USA/OBI-Mexico are developing new
generations of external and implantable medical devices based
on UNCD coatings, namely: a) UNCD-coated silicon-microchip
implantable inside the eye as key component of artificial retina,
returning partial vision to people blind by genetically-induced degeneration
of photoreceptors (Argus II device marketed by Second
Sight in Europe and USA); b) new generation of Li-ion batteries
with ≥ 10x longer life and safer, using UNCD-coated electrodes,
membranes and inner wall battery case, enabling ≥ 15-20 years
defibrillator/pacemakers and cell phones charged every 2-3 days;
c) new generation of implantable prostheses (e.g., dental implants,
hips, knees) coated with UNCD eliminates failure of current
metal-implants due to mechanical wear / chemical corrosion by
body fluids; d) N-UNCD-coated polymer with brain neurons tailored
stiffness enables less invasive neural stimulation electrodes;
e) UNCD- coated masks for trapping more efficiently COVID-19
virus, due to ≤ 20 nm pores vs micron size pores in current masks;
f) Electrically conductive/water corrosion resistant Boron-doped
UNCD-coated metal electrodes for water purification and cleaning
of mask via generation of ozone, killing all virus, bacteria, and
every pathogen on surfaces.
