Evaluation of surface layer stability of surface-modified polyester biomaterials
Biointerphases, 2020 Surface modification of biomaterials is a strategy used to improve cellular and in vivo outcomes. However, most studies do not evaluate the lifetime of the introduced surface layer, which is an important aspect affecting how a biomaterial will interact with a cellular environment both in the short and in the long term.

Concentrator of laser energy for thin vapour cloud production near a surface [PDF]
, 1998 A novel scheme is presented for production of a thin ($100$ cm$^2$) by pulsed laser ablation of a solid surface. Instead of dispersing the laser energy uniformly over the surface, a modified Fabry-Perot interferometer is employed to concentrate the laser

A Thermal Plume Model for the Martian Convective Boundary Layer [PDF]
, 2013 The Martian Planetary Boundary Layer [PBL] is a crucial component of the Martian climate system. Global Climate Models [GCMs] and Mesoscale Models [MMs] lack the resolution to predict PBL mixing which is therefore parameterized.
