The effects of high power diode laser radiation on the wettability, adhesion and bonding characteristics of an alumina/silica-based oxide and vitreous enamel [PDF]

open access: yes, 1999
An amalgamated alumina/silica-based oxide compound (AOC) was surface treated using a 60 W high power diode laser (HPDL). The effects of HPDL radiation on the wettability and adhesion characteristics of the AOC and a vitreous enamel have been determined.

Electrochemical micro-structuring of graphite felt electrodes for accelerated formation of electroactive biofilms on microbial anodes. [PDF]

open access: yes, 2011
Electroactive biofilms were formed on graphite felt anodes under constant potential polarisation using compost leachate as the inoculum and dairy waste as the substrate. A new surface treatment is presented that consists of creating micro-cavities on the
