Flexible Thin‐Film Heater Composed of Laser‐Induced Graphene and Poly(D, L‐Lactic Acid) with Electro‐ and Photo‐Thermal Properties toward Cancer Thermotherapy

open access: yesAdvanced Electronic Materials, EarlyView.
This study introduces a thin‐film‐type heat‐generating device that uses laser induced graphene (LIG) on a poly(D, L‐lactic) acid film, which realizes both resistance heating by direct current application and photothermal conversion heating by near‐infrared light irradiation.

Shape and fission instabilities of ferrofluids in non-uniform magnetic fields

open access: yes, 2017
We study static distributions of ferrofluid submitted to non-uniform magnetic fields. We show how the normal-field instability is modified in the presence of a weak magnetic field gradient.
