Suppressing the coffee-ring effect of colloidal droplets by dispersed cellulose nanofibers
We report that the addition of a small amount of cellulose nanofibers (CNFs) into an aqueous dispersion of colloidal particles suppresses the coffee-ring effect when the dispersion dries on a solid substrate, as revealed by the computational analysis of experimental time-series images and by particle image velocimetry. The addition of CNFs is much more effective than the increase of colloidal p...
متن کاملAcoustic suppression of the coffee-ring effect.
We study the influence of acoustic fields on the evaporative self-assembly of solute particles suspended inside sessile droplets of complex fluids. The self-assembly process often results in an undesirable ring-like heterogeneous residue, a phenomenon known as the coffee-ring effect. Here we show that this ring-like self-assembly can be controlled acoustically to form homogeneous disc-like or c...

Experimental methods Preparation of the IDT. The IDT device was fabricated as described previously [1, 2], employing standard photolithography. The device consisted of gold interdigitated electrodes, with a pitch d=350 µm, and width w=175 µm on a 128 o Y-cut X-propagating 3 inch LiNbO 3 wafer, patterned using lift-off process. The aperture of the device was 20 mm. The resonance frequency of the...

The efficient introduction of somatic mutations in a given gene, at a given time, in a specific cell type will facilitate studies of gene function and the generation of animal models for human diseases. We have shown previously that conditional recombination-excision between two loxP sites can be achieved in mice by using the Cre recombinase fused to a mutated ligand binding domain of the human...
