Thermal Induced Changes in Cuticle and Cortex to Chemically Treated Hair. [PDF]

open access: yesBiopolymers
ABSTRACT The deterioration of the cuticle and cortex hair due to routine cosmetic practices has been identified as a primary factor contributing to undesirable changes in the esthetic qualities of hair. Chemical and physical treatments can cause significant damage to hair fibers.

Superstability of micrometre jets surrounded by a polymeric shell. [PDF]

open access: yesJ Appl Crystallogr
Superstable 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 ...
