Graphene Layers as Functional Biomaterials. From Fabrication and Characterization to Biological Applications

Advanced Materials Interfaces, EarlyView.
Graphene layers are fabricated on Cu foil and transferred onto glass substrates to form double‐ and multi‐layer G‐glass. Raman spectroscopy confirms structural integrity, while SEM and fluorescence microscopy reveal favorable adhesion and spreading of L‐929 fibroblast cells.

A Markov Point Process model for wrinkles in human faces

, 2012
International audienceIn this paper we present a new generative model for wrinkles on aging human faces based on Markov Point Processes (MPP) where wrinkles are considered as stochastic spatial arrangements of sequences of line segments.

Smart Electrospun Nanofibers for Controlled Oil‐Water Separation

Advanced Materials Interfaces, EarlyView.
Stimuli‐responsive electrospun nanofibers are reviewed as advanced platforms for controlled oil/water separation. The effects of surface wettability, porous structure, and external stimuli, including pH, temperature, gas, and light, on separation performance are discussed.

Low‐Pressure Plasma‐Based Wrinkling of PDMS and Machine Learning‐Driven Property Engineering

Advanced Materials Technologies, EarlyView.
Wrinkled surfaces are well‐suited for controlled surface deformations in the µm range. The key challenge is the relation between the resulting wrinkle features and the necessary process conditions. Machine learning techniques have solved the prediction and inverse design problems for various preparation conditions, opening a precisely controlled ...
