Advanced Functional Materials, EarlyView.Top‐down organic pillaring expands the interlayer spacing of bulk‐sized MoS2 particles while preserving the bulk morphology. Operando X‐ray diffraction and electrochemical dilatometry show that MoS2‐bulk undergoes solvent co‐intercalation in diglyme electrolyte, causing large structural expansion, while pillared, expanded MoS2 suppresses solvent uptake

Implementation of a Hydraulic Power Take-Off for wave energy applications [PDF]
, 2013 The main purpose of the following work is to implement a hydraulic power take-off system coupled with the dynamic model of a wave energy converter. In this work the Wavestar concept will be used without any losses of the general principle since the power take-off sub-model can be coupled with any device, if a relative motion between to body is ...
