An evaporating colloidal particle–laden droplet leaves behind a ring-like residue after drying. We routinely observe this ubiquitous phenomenon for dried coffee drops; thus, it is known as the "coffee ...

Cornell researchers have developed a two-phase liquid crystal system that can rapidly change—and hold—its shape, transforming ...

Four patterned surfaces with hydrophilic areas of different sizes were prepared using photolithography with a smooth octadecyltrimethoxysilane (ODS) hydrophobic coating. The hydrophilic area in the ...

Scientists uncover how hydrophobic surfaces trap nanoplastics, offering fresh insight into their movement and impact on soil ...

We explore the prospects of a perturbation approach for predicting how weak attractive interactions affect collapse thermodynamics of hydrophobic polymers in water. Specifically, using molecular ...
