Bilayered PEDOT:PSS–Collagen Scaffolds as Functional Architectures for Tissue Engineering

open access: yesAdvanced Materials Interfaces, EarlyView.
A bilayered scaffold integrates collagen and PEDOT:PSS as distinct yet interconnected 3D matrices, preserving their fibrillar and conductive characteristics. Spatial compartmentalization enables independent tailoring of each domain while maintaining mechanical stability and compatibility with electrochemical monitoring, providing a multifunctional ...

Ice Composition and Glacier Dynamics

1991
The study of ice composition represents an effective tool in our understanding of the dynamics of glaciers, ice sheets and ice shelves. The authors of this work relate the distribution of isotopes and impurities in ice masses to ice flow, to the key zone close to the ice-substratum interface and to the mechanisms effective in the contact zone between ...

Surface Ices and the Atmospheric Composition of Pluto

Science, 1993
Observations of the 1.4- to 2.4-micrometer spectrum of Pluto reveal absorptions of carbon monoxide and nitrogen ices and confirm the presence of solid methane. Frozen nitrogen is more abundant than the other two ices by a factor of about 50; gaseous nitrogen must therefore be the major atmospheric constituent.
