Fluorescent Microspheres as Tags for Anti-Counterfeiting of Textiles

Ivanova O.S., Campbell T.A., Virginia Tech, US

The goal of this project is to create an anti-counterfeiting system for textiles that takes advantage of advanced materials and mobile readers. Current anti-counterfeiting systems are challenged in achieving the desired characteristics of lack of [...]

Additive Manufacturing (AM) of Quantum Dot Nano-Inks

Ivanova O.S., Elliott A., Campbell T.A., Williams C.B., Virginia Tech, US

Additive Manufacturing (AM) pertains to technologies that fabricate 3D artifacts through the successive addition of 2D cross-sectional layers. Due to this layer-by-layer fabrication process, AM allows a designer to create geometrically complex artifacts with designed [...]

Synthesis of Non-Spherical CdSe Quantum Dots

Ivanova O.S., Zimmermann K.A., Campbell T.A., Virginia Tech, US

Here we describe the synthesis of non-spherical CdSe quantum dots (QDs) through high temperature reduction in the presence of TOP (Tri-n-octylphosphine) and TOPO (Tri-n-octylphosphine oxide). High affinity of phosphine oxide to the surface of CdSe [...]
