Journal ArticleDOI
Security printing of covert quick response codes using upconverting nanoparticle inks
TL;DR: This research demonstrates that QR codes, which have been used primarily for information sharing applications, can also be used for security purposes, and it was shown that this security ink can be optimized for line width, thickness and stability on different substrates.
Journal ArticleDOI
Red-green-blue printing using luminescence-upconversion inks
TL;DR: In this article, an RGB additive-color printing system that produces highly-resolved pre-defined patterns that are invisible under ambient lighting, but which are viewable as luminescent multi-color images under NIR excitation is presented.
Journal ArticleDOI
Patterned direct-write and screen-printing of NIR-to-visible upconverting inks for security applications.

TL;DR: Two methods of direct-write printing for producing highly resolved features of a polymer impregnated with luminescent upconversion phosphors for security applications are presented.
Journal ArticleDOI
Enhanced thermal conductivity by aggregation in heat transfer nanofluids containing metal oxide nanoparticles and carbon nanotubes
Jesse Wensel,Brian Wright,Dustin Thomas,Wayne Douglas,Bert Mannhalter,William M. Cross,Haiping Hong,Jon J. Kellar,Pauline Smith,W.N. Roy +9 more
TL;DR: In this paper, an approximately 10% increase in thermal conductivity of heat transfer nanofluids containing metal oxide nanoparticles and carbon nanotubes was determined with very low percentage loading (around 0.02wt%) of these two nanomaterials.
Journal ArticleDOI
Determining the interphase thickness and properties in polymer matrix composites using phase imaging atomic force microscopy and nanoindentation
TL;DR: In this paper, the authors used phase imaging AFM and nanoindentation to examine the interphase in a glass fiber-reinforced epoxy matrix composite and found that the relatively stiff fiber might have caused a gradient in the modulus across the inter-phase region.
