Piecewise continuous distribution function method: Fluid equations and wave disturbances at stratified gas

, 2005
Wave disturbances of a stratified gas are studied. The description is built on a basis of the Bhatnagar -- Gross -- Krook (BGK) kinetic equation which is reduced down the level of fluid mechanics.

Laser‐Assisted Phase Engineering of 2D MoS2 for Efficient Solution‐Processed Electronics

Advanced Materials, EarlyView.
Here, local laser‐assisted phase transition from solution‐processed phase‐pure 1T′ to 2H MoS2 is shown to critically depend on the irradiation atmosphere. While processing in air leads to damaged insulating regions, inert conditions yield semiconducting 2H domains, enabling direct field‐effect transistor patterning with optimized lateral 1T′‐2H MoS2 ...

Observation of Surface-Avoiding Waves: A New Class of Extended States in Periodic Media

, 2006
Coherent time-domain optical experiments on GaAs-AlAs superlattices reveal the exis-tence of an unusually long-lived acoustic mode at ~ 0.6 THz, which couples weakly to the environment by evading the sample boundaries. Classical as well as quantum states

Investigation of Structural, Mechanical and Electrochemical Properties of Temperature‐Dependent Dual AlN/TiAlN Coating Synthesized by CVD Process

Advanced Materials Interfaces, EarlyView.
This study investigates thermally CVD‐deposited AlN/TiAlN dual‐layer coatings over a Si substrate, focusing on the temperature‐dependent process‐structure relationship. Systematic characterization reveals that a dense AlN interlayer combined with an optimally deposited TiAlN top layer provides enhancement in mechanical strength, tribological stability,
