Theoretical design of carrier injection rate and recombination rate in tunnel injection quantum well lasers

physica status solidi c, 2008
AbstractCarrier injection rate in tunnel injection quantum well structures used in semiconductor lasers was investigated through theoretical analysis. Carrier capture time from 3D‐state to 2D‐state in a conventional quantum well was several ten picoseconds and it is almost uncontrollable characteristics.

Effects of variable injection rate on reservoir responses and implications for CO 2 storage in saline aquifers

Greenhouse Gases: Science and Technology, 2019
Past reservoir simulations of carbon dioxide (CO2) storage in saline aquifers have shown that the injection procedure can influence CO2 storage efficiency and injectivity.

Deformational injection rate measuring method

Review of Scientific Instruments, 2002
After completing the diesel engine endurance testing, we detected various traces of thermal load on the walls of combustion chambers located in the engine pistons. The engines were fitted with ω combustion chambers. The thermal load of different intensity levels occurred where the spray of fuel, fuel vapor, and air interacted with the combustion ...

Effect of Variable Injection Rate on Falloff and Injectivity Tests

SPE Western Regional/AAPG Pacific Section Joint Meeting, 2002
Abstract Numerous full field water-flooding projects are currently under way throughout the world to improve recovery. In many large oil fields water injection is initiated during the early stages of reservoir development. Exploratory wells are tested for injectivity, and injectors are tested during the field operation.

Complication Rate of Power Coronary Angiography Injection

Angiology, 1980
From 1970 to 1975, 1,498 patients underwent coronary angiography at Wilford Hall USAF Medical Center via the same injection technique utilizing a Viamonte Hobbs automatic volume injector. Most institutions now perform coronary angiography by hand injections of contrast medium, and automatic power injection angiography is reserved for ventriculograms ...

Response of Induced Seismicity to Injection Rate Reduction: Models of Delay, Decay, Quiescence, Recovery, and Oklahoma

Water Resources Research, 2018
When injection‐induced seismicity poses a risk to communities, it is common to reduce the injection rate or halt operations. This applies both to individual wells and well clusters, such as those within the Area of Interest for Triggered Seismicity in ...

Cooling Rate Influence in Bonded Magnet Injection Moulding

International Journal of Material Forming, 2010
Recently the use of injection moulded bonded magnets has become very widespread. This is mainly due to the interesting price of injection moulded magnets. However the process is actually limited by some critical aspects that are related to rheological and thermal properties of the melt.

A numerical investigation on the injection timing of boot injection rate-shapes in a kerosene-diesel engine with a clustered dynamic adaptive chemistry method

Applied Energy, 2018
In this study, we conducted a numerical investigation on the effect of injection timing of boot injection rate shape on the combustion and emission characteristics in a direct injection compression ignition (DICI) engine fueled with kerosene/diesel ...

High strain-rate response of injectable PAA hydrogel

Journal of Biomaterials Science, Polymer Edition, 2015
Hydrogel materials have been widely considered as potential soft tissue replacements because of their high permeability, hydrophilicity, and biocompatibility, as well as their low coefficient of friction. Injectable (thermo-responsive) hydrogels can provide support and cushioning at irregularly shaped disease sites, and are thus suitable for use in ...
