‘A devotion to the experimental sciences and arts’: the subscription to the great battery at the Royal Institution 1808–9 [PDF]

open access: yes, 2007
A significant but neglected theme in the history of British science in the nineteenth century is the funding of institutional research. The subscription to the ‘great battery’ at the Royal Institution in 1808 and 1809 provides the first instance of named

Improved thermal isolation of silicon suspended platforms for an all-silicon thermoelectric microgenerator based on large scale integration of Si nanowires as thermoelectric material [PDF]

open access: yes, 2015
Special suspended micro-platforms have been designed as a part of silicon compatible planar thermoelectric microgenerators. Bottom-up grown silicon nanowires are going to bridge in the future such platforms to the surrounding silicon bulk rim.
