Abstract: Inkjet printing is a powerful technology for realizing high‐density pixelated perovskite light‐emitting diodes (PeLEDs). However, the coffee‐stain effect in the inkjet printing process often leads to uneven thickness and poor crystallization of printed perovskite features,… read more here.

Abstract: Cetyltrimethylammonium bromide (CTAB)-stabilized low-aspect ratio gold nanorods have been synthesized using seed-mediated wet chemical approach. Freshly cleaved highly oriented pyrolytic graphite (HOPG) surface is used as a substrate for the deposition of nanoparticles via the… read more here.

DOI: 10.1016/j.colsurfa.2021.127386
Abstract: Abstract One disadvantage of using the hydrophobic surface technique to suppress coffee-stain effect is that it requires hydrophobization of a relatively large area of hydrophilic surface. The opposite technique, which involves coating a particle suspension… read more here.

Abstract: Carbon nanotube (CNT) based binder-free, syringe-printable inks, with graphene oxide (GO) being used as the dispersant, have been designed and developed. We discovered that the printability of the ink is directly attributed to the uniform… read more here.
