Ingeniería e Investigación, 2001 Desde hace aproximadamente 30 años, el mundo dela ciencia se revolucionó debido al nacimiento de un nuevo paradigma; a esta forma de ver el mundo se le conoce con el nombre de Teoría del Caos. En su corta vida, ya “ha tocado todas las ramas del conocimiento, incluyendo por supuesto la Ingeniería” dice Mora (1998).

Superstability of micrometre jets surrounded by a polymeric shell. [PDF]
J Appl CrystallogrSuperstable micrometre compound jets have been produced for serial femtosecond X‐ray crystallography.We have produced superstable compound liquid microjets with a 3D‐printed coaxial flow‐focusing injector. The aqueous jet core is surrounded by a shell, a few hundred nanometres in thickness, of a low‐concentration aqueous solution of a low‐molecular ...
