Resonance Raman spectroscopy offers several advantages in the studies of ink jet prints stemming from its inherent selectivity and sensitivity. These include the possibility to obtain direct information on the chemical interactions between the paper and ink that play a major role in long-term print fastness. However, resonance Raman techniques can suffer from obtrusive fluorescence from coloran...

The success of printing technology in the electronics industry primarily depends on the availability of metal printing ink. Various types of commercially available metal ink are widely used in different industries such as the solar cell, radio frequency identification (RFID) and light emitting diode (LED) industries, with limited usage in semiconductor packaging. The use of printed ink in semic...

To visualize completely rat retinal microvessels, the gelatin-ink perfusion condition was systematically optimized using von Willebrand factor (vWf) immunostaining as control. Whether the vessel showed by the new perfusion condition can be used for double label with neurons or glial cells in the same retina was also tested. Our results showed that infusing rats first with 20 ml of 37 degrees C ...

Handwriting is one of the most natural ways for a human to record knowledge. In recent years this type of human-computer interaction has received increasing attention due to the rapid evolution of digital ink hardware. This thesis contributes to the art of efficient recognition of handwriting and compact storage of digital ink. In the first part of the thesis, we focus on the development of alg...

Recent advancements in 3D bioprinting have led to the fabrication of more complex, more precise, and larger printed tissue constructs. As the field continues to advance, it is critical to develop quantitative benchmarks to compare different bio-inks for key cell-biomaterial interactions, including (1) cell sedimentation within the ink cartridge, (2) cell viability during extrusion, and (3) cell...
