Mechanism of GaAs surface sulfidation

open access: yes, 2014
The mechanism of GaAs sulfidation under illumination and potentiodynamic polarization was investigated in acidified thiourea (TU) electrolytes. Sulfidation generated smooth surfaces, as revealed by scanning electron microscopy and atomic force microscopy

Waveguide Photoactuators: Materials, Fabrication, and Applications

open access: yesAdvanced Robotics Research, EarlyView.
Waveguide photoactuators convert guided light into mechanical motion. Their tethered‐flexible design enables minimally invasive surgery and confined‐space robotics. This review aims to guide materials selection, device design, and system integration, accelerating the transition of waveguide photoactuators from laboratory prototypes to versatile ...

Development Accounting with Intermediate Goods [PDF]

open access: yes
Do intermediate goods help explain relative and aggregate productivity differences across countries? Three observations suggest they do: (i) intermediates are relatively expensive in poor countries; (ii) goods industries demand intermediates more ...

Surface-dependent sulfidation and orientation of MoS 2 slabs on alumina-supported model HDS catalysts

open access: yes, 2016
International audienceThe constant improvement of hydrotreating (HDT) catalysts, driven by industrial and environmentalneeds, requires a better understanding of the interactions between the oxide support (mostly alumina)and the MoS2 active phase.

Recent Advances in Laser‐Induced Graphene‐Based Gas Sensors: From Sensing Mechanisms to Biomedical Applications

open access: yesAdvanced Science, EarlyView.
Laser‐induced graphene (LIG) provides a scalable, laser‐direct‐written route to porous graphene architecture with tunable chemistry and defect density. Through heterojunction engineering, catalytic functionalization, and intrinsic self‐heating, LIG achieves highly sensitive and selective detection of NOX, NH3, H2, and humidity, supporting next ...

ZnO-ZnS porous films by sulfidation of three-dimensional ZnO porous templates: Evolution of inward growth during sulfidation process

open access: yes, 2018
ZnO-ZnS porous films were formed by low-temperature sulfidation of three-dimensional (3D) ZnO porous templates. The conversion of ZnO to ZnS initialized at the ZnO surface, accompanied by volume expansion.
