Piston ring assembly for a new natural gas vehicle symmetrical multistage wobble-plate compressor [PDF]

open access: yes, 2006
Natural gas is an alternative fuel of choice in the market today due to the increase in the price of petroleum, as well as out of environmental concerns. Pressure requirement for a natural gas vehicle (NGV) storage tank is 3000 psig (206 bars).

Confining Surface Oxygen Redox in Double Perovskites for Enhanced Oxygen Evolution Reaction Activity and Stability

open access: yesAdvanced Energy Materials, EarlyView.
The double perovskite BaSrNiWO6 is developed as an oxygen evolution reaction catalyst. B‐site W6+ dissolution drives in situ reconstruction of the surface to a disordered, NiO‐like layer. Consequently, local oxygen species are activated for a surface lattice oxygen evolution mechanism (sLOEM).

The axial motion of a piston ring in the piston ring groove

open access: yes, 1983
The piston ring axial motion model developed by Furuhama, Dowson and Hoult was modified using the parallel plate squeeze equation to account for oil in the ring grooves. The improved model was used to predict ring motion and the ring transition time from one ring land to the other.

Metal Sulfides as Potential Materials for Next Generation Lithium Ion Batteries: A Review

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
The flame spray pyrolysis (FSP) method demonstrates its superiority in fabricating metal sulfide‐based electrodes without inactive materials like organic binders or solvents. The particles are directly deposited and compressed onto the electrode surface, integrating into continuous production.

Dynamic analysis of gas flow through the ICE ring seal [PDF]

open access: yes, 2019
(1) Purpose: The effect of axial movement of piston rings in the piston grooves is estimated by calculation and experimentally for the passage of gases in an internal combustion engine (ICE). (2) Methodology: When modeling the effect of axial movement of

Zero‐Valent Iron Nanoparticles Supported on Si/N Codoped Carbon Materials: From Biomass to Oxygen Reduction Electrocatalysts and Supercapacitors

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Zero‐valent iron nanoparticles on Si/N codoped carbon support are prepared from hydrothermal carbonization and pyrolysis of biomass, silica, and iron salt. The Fe nanoparticles are evenly distributed on the support and encapsulated in graphitic or iron oxide shells.

Numerical experiments on vortex ring formation [PDF]

open access: yes, 2001
Numerical simulations are used to study the formation of vortex rings that are generated by applying a non-conservative force of long duration, simulating experimental vortex ring generation with large stroke ratio. For sufficiently long-duration forces,
