Scientists used a 3D-printing approach to pattern hydrophobic barriers inside hydrophilic filter paper. These barriers, designed in different geometries, guide liquids along precise paths and shape ...

These days, it's hard to imagine life without coffee. Even if you can't abide the stuff, only drink decaf, or prefer a tall glass of sweet tea, coffee plays an important part in culture in the South ...

3D printing creates hydrophobic barriers in hydrophilic paper, guiding liquids along precise paths for controlled mixing, gradients, and two-phase separation. (Nanowerk News) Filter paper plays ...
