Advanced Porous Materials for Maritime Carbon Capture

open access: yesAdvanced Materials, EarlyView.
Carbon capture from emission sources, such as marine vessels, has attracted significant attention over the years. To achieve this goal, sorbents such as metal–organic frameworks (MOFs), porous polymer networks (PPNs), covalent organic frameworks (COFs), and their post‐synthetic modifications are currently being explored.

Lightweight piston [PDF]

open access: yes, 1987
A lightweight piston composed of carbon-carbon composites is presented. The use of carbon-carbon composites over conventional materials, such as aluminum, reduces piston weight and improves thermal efficiency of the internal combustion reciprocation ...

The N.A.C.A. Combustion Chamber Gas-sampling Valve and Some Preliminary Test Results [PDF]

open access: yes
A gas sampling valve of the inertia-operated type was designed for procuring samples of the gases in the combustion chamber of internal combustion engines at identical points in successive cycles so that the analysis of the gas samples thus procured may ...

Experimental and Numerical study of a hydrogen fuelled I.C. engine fitted with the hydrogen assisted jet ignition system [PDF]

open access: yes, 2007
The use of hydrogen as an engine fuel poses several challenges as well as opportunities in engine design and control. These challenges are mainly due to hydrogen's high flame temperatures at near stoichiometric mixtures, as well as the reactant volume ...
