Reversible Phase Transitions of Anionic and Cationic Surfactant Mixtures Drive Shape Morphing Droplets

Advanced Materials, EarlyView.
A light‐controlled, reversible phase transition of ionic surfactant assemblies, coupled with dynamic partitioning between bulk phases and interfaces, induces rapid, and order‐of‐magnitude changes in oil–water interfacial tension. Surpassing the capabilities of conventional stimuli‐responsive surfactants, this transient, collaborative mechanism enables ...

Multiwavelength excitation Raman Scattering Analysis of bulk and 2 dimensional MoS2: Vibrational properties of atomically thin MoS2 layers

, 2015
In order to deepen in the knowledge of the vibrational properties of 2-dimensional MoS2 atomic layers, a complete and systematic Raman scattering analysis has been performed using both bulk single crystal MoS2 samples and atomically thin MoS2 layers ...

New Perspectives on Semiconducting Conjugated Oligomers for Neuromodulation in Hydra vulgaris

Advanced Materials Interfaces, EarlyView.
Semiconducting organic compounds, thiophene‐based, modify the rhythmic electrical activity of the cnidarian Hydra vulgaris acting on specific neuronal circuits. The ETE‐S trimer also forms electronically conducting wires in the living tissues of the animal.

Periodic spatial variation of the electron-phonon interaction in epitaxial graphene on Ru(0001 [PDF]

, 2013
We have performed low temperature scanning tunnelling spectroscopy (STS) measurements on graphene epitaxially grown on Ru(0001). An inelastic feature, related to the excitation of a vibrational breathing mode of the graphene lattice, was found at 360 meV.

High Magnetic Sensitivity at the Coercive Field Induced by Shear Horizontal SAW in Polycrystalline FeGa Films

Advanced Materials Technologies, EarlyView.
A theoretical framework links stress‐induced changes in the Young's modulus of Fe₇₂Ga₂₈ layers to their magnetization dynamics under SH‐SAW excitation. This interaction produces a sharp sensor response near the coercive field, highlighting FeGa's magnetoelastic sensitivity.
