Nitride semiconductor laser device

A nitride semiconductor laser device has a group III nitride semiconductor multilayer structure. The group III nitride semiconductor multilayer structure includes an n-type semiconductor layer, a p-type semiconductor layer and a light emitting layer held between the n-type semiconductor layer and the p-type semiconductor layer, and the p-type semiconductor layer is formed by successively stacking a p-side guide layer, a p-type electron blocking layer in contact with the p-side guide layer and a p-type cladding layer in contact with the p-type electron blocking layer from the side closer to the light emitting layer. The p-side guide layer is formed by stacking a layer made of a group III nitride semiconductor containing Al and a layer made of a group III nitride semiconductor containing no Al. The p-type cladding layer is made of a group III nitride semiconductor containing Al, and the p-type electron blocking layer is made of a group III nitride semiconductor having a larger Al composition than the p-type cladding layer.

System and method for operating an internal combustion engine with hydrogen blended with conventional fossil fuels

A system for retrofitting an internal combustion engine to use a proportion of hydrogen gas and existing fossil fuel is disclosed. The system is comprised of a source of hydrogen gas and means for delivering hydrogen gas to the combustion chamber of the engine. The engine operating parameters are adjusted and the delivery of hydrogen is controlled to provide selective introduction of hydrogen gas throughout the engine's operating cycle. The source of hydrogen gas can comprise an onboard hydrogen reformer, or hydrogen and carbon monoxide can be reformed inside the cylinder from an on board carrier of hydrogen. A single point injector placed at the intake manifold in close proximity to the engine intake valve can be used to mix the hydrogen gas to the air / fossil fuel mixture or sequential injectors can deliver hydrogen in close proximity to each engine intake valve, or directly into each cylinder.
