   • Super Thin Glass: SAIC of McLean, Virginia, and NREL have been developing a front surface mirror concept with a hardcoat protective layer. The material uses an ion-beam-assisted deposition (IBAD) process to deposit the very hard (cleanable), dense (protective) alumina topcoat. 2017, Yogi Goswami, Advances in Solar Energy, volume 16:
   • Another transparent material for passivation is silicon nitride, Si₃N₄, that also acts as hardcoat. 2012, Michael Quinten, A Practical Guide to Optical Metrology for Thin Films:
   • Such brute-force tactics generally fail for hardcoats on flexible substrates and there seems to be no correlation between scratch resistance and modulus once a certain minimum modulus (~1 GPa) has been reached. 2013, Steven Abbott, Nigel Holmes, Nanocoatings: Principles and Practice: From Research to Production, page 255:
