摘要： According to an example, methods for forming three-dimensional (3-D) nano-particle assemblies may include depositing surface-enhanced spectroscopy (SES) elements onto respective tips of nano-fingers, in which the nano-fingers are arranged in sufficiently close proximities to each other to enable the tips of groups of adjacent ones of the nano-fingers to come into sufficiently close proximities to each other to enable the SES elements on the tips to be bonded together when the nano-fingers are partially collapsed. The methods also include causing the nano-fingers to partially collapse toward adjacent ones of the nano-fingers to cause a plurality of SES elements on respective groups of the nano-fingers to be in relatively close proximities to each other and form respective clusters of SES elements, introducing additional particles that are to attach onto the clusters of SES elements, and causing the clusters of SES elements to detach from the nano-fingers.

摘要： The present disclosure describes methods of printing, textile printing systems, and printers. In one example, a method of printing can include jetting an ink composition onto a substrate, the ink composition including an evaporable solvent, a colorant, and a non-curable polymeric binder. The ink composition on the substrate can be exposed to electromagnetic radiation having a wavelength from 350 nm to 420 nm. The exposure of the ink composition can begin from 0 ms to 600 ms after jetting the ink composition. The electromagnetic radiation can heat the ink composition to evaporate a portion of the evaporable solvent from the ink composition within 5 ms to 500 ms after the beginning of the exposure.

摘要： The present disclosure relates to an Inkjet printing process that comprises inkjet printing an inkjet ink composition onto a substrate to form a printed inkjet ink layer. The inkjet ink composition comprises a colorant, a curable polyurethane dispersion, a photoinitiator and water, wherein the amount of curable polyurethane dispersed in the inkjet ink composition is 0.1 to 30 weight %. A radiation-curable overcoat composition is applied over the printed inkjet ink layer as an overcoat layer. The overcoat composition comprises a curable polyurethane dispersion, a photoinitiator and water. The printed inkjet ink layer is then cured on the substrate by exposing both the overcoat layer and inkjet ink layer on the substrate to radiation.
