capping layer

A common strategy is to place the acid-generating material under benign capping layers.

This capping layer helped protect the softer stone below it from erosion.

One prominent approach involves the use of a strain-inducing capping layer.

Such metals are reactive, so they require a capping layer of aluminium to avoid degradation.

Below the capping layer, the air is moist and has convection with the presence of stratocumulus clouds.

We are not surprised to learn that over-specification is widespread, particularly for fill, hardcore and capping layers in road construction.

Finally, a silicon oxynitride/nitride layer is deposited on the top surface as a capping layer.

Extra integration steps, such as a thermal bake-out or deposition of a capping layer, are required to retain the integrity of the film.

The above design guide provides advice regarding the thickness of sub-base and capping layers for a given CBR value.

The largest layer is that from the top of the tropopause to a capping layer around 700 hPa which is described by descending warm air.

The capping layer will consist of a running surface with a minimum thickness of 0.6 metres, covered by a layer of growing medium.

Drainage of Landfill capping Landfill capping layers often consist of a mineral sealing layer which prevents surface water from being introduced into the waste material.

TRANSCAP-1D is a numerical model that simulates the vertical migration of dissolved contaminants through a subaqueous capping layer.

Standard lithography patterning techniques can be used to selectively deposit strain-inducing capping layers, to deposit a compressive film over only the PMOS, for example.

Capping layers are key to the Dual Stress Liner (DSL) approach reported by IBM-AMD.

Because this turbidite covered contaminated sediments, the resuspension potential of surficial sediments is an important parameter in order to determine efficiency of the 1996 layer, to act as a capping layer.

Capping layers are simply layers of a selected fill material, often a crushed rock, laid in layers not exceeding 225mm (normally) and thoroughly compacted before placing further layers, up to sub-base layer.

This document deals specifically with issues relating to designing, constructing and validating of bentonite enriched soil (BES) liners and capping layers whose primary function is to contain pollutants arising from landfilled waste.

Thereafter several numerical simulations with variable bio-irrigation depth and variable thickness of the capping layer were performed to test the effect of the uncertainty and variability of the input values on the model response.

CVD silicon nitride is a common choice for a strained capping layer, in that the magnitude and type of strain (e.g. tensile vs compressive) may be adjusted by modulating the deposition conditions, especially temperature.

Capping layer If the subgrade is weak, a capping layer of relatively cheap material can be placed between the subgrade and the sub-base to improve the strength of the structure.

A final capping layer was added to prevent leakage; a landfill gas control system was used to deploy methane from the decomposed rubbish as fuel, and a leachate management system was built to collect leachate for further processing.

While RTA without a capping layer produced only minor changes in the PL spectrum, the combination of a 300 nm SiO2 overlayer plus RTA caused a shift to lower energy of the main PL peak.
