Recent Progress in the Phase‐Controlled Synthesis of Ruthenium Nanocrystals for Catalytic Applications

open access: yesAdvanced Materials, EarlyView.
Template effect and kinetic control enable crystal‐phase engineering of Ru nanocrystals, granting access to either metastable fcc‐Ru or stable hcp‐Ru with distinct surface structures, thermal stabilities, and catalytic behaviors. Moreover, the hcp‐Ru can further serve as an epitaxial template to direct Pd and Rh nanocrystals into the metastable hcp ...

Data on Internal Rarefied Gas Flows

Journal of Physical and Chemical Reference Data, 1998
The present review, containing 178 references, is dedicated to one of the largest and most important branches of the rarefied gas dynamics, namely internal flows. A critical analysis of the corresponding numerical data and analytical results available in the literature was made. The most reliable data were selected and tabulated.

Poiseuille flow of a rarefied gas mixture

Zeitschrift für angewandte Mathematik und Physik ZAMP, 1978
The flow of a rarefied binary gas mixture is governed by transport equations which correspond to a coupled set of Fredholm integral equations of the second kind. By means of the Fourier transform technique and by expanding the transformed kernels in terms or orthogonal functions the problem is reduced to the solution of a system of linear algebraic ...

Thermophoresis in Rarefied Gas Flows

Aerosol Science and Technology, 2002
Numerical calculations are presented for the thermophoretic force acting on a free-molecular, motionless, spherical particle suspended in a rarefied gas flow between parallel plates of unequal temperature. The rarefied gas flow is calculated with the direct simulation Monte Carlo (DSMC) method, which provides a time-averaged approximation to the local ...

Flow of Rarefied Gas over Plane Wall

The Physics of Fluids, 1970
Flow of rarefied gas over an infinite plane wall on the basis of a relaxation model of the Boltzmann equation is considered. The solution is obtained in the form: Hilbert solution and boundary layer term which is appreciable only in a thin layer (with thickness of order of the mean free path) adjacent to the boundary.
