Infill material

Lanthanide-doped inverse photonic crystals have been reported.282 The lattices were prepared by infilling self-assembled polystyrene sphere templates with a mixture of zirconium alkoxide and europium at 450 °C, the polystyrene spheres were burnt out leaving hollow spheres of air, and the infilled material was converted to Zr02 Eu3+. The PL properties of the resulting photonic lattice were reported.282 The possibility of including phosphors into photonic lattices could lead to many... 

The Consumer Safety Regulations 1988 regulations were recently published for domestic furniture and mattresses. These are a complex series of relatively simple ignition tests designed to restrict the use of easily ignitable fabrics and infill materials. The 1988 regulations replace the earlier regulations of 1980 and 1983. 

Since iron oxides and iron oxyhydroxides are commonly found as fracture-infilling materials, samples with a particle size of 100 to lS um were contacted with granite groundwater containing ... 

In some fractures alterations and somewhat increased porosity of the rock can be observed a few cm from the fracture surface. In this region molecular diffusion would be further facilitated. Some fractures contain fracture infill materials that also can add to the sorption and retardation effects. 

Further improvements of the model may incorporate different aspects such as the influence of the formation of infilling material due to shear displacements between crack interfaces. Lee and Cho (2002) have investigated the variation of intrinsic permeability when fractured rocks (granite and marble) are subjected to normal and shear deformations. This work shows that mechanical and hydraulic apertures are not always in linear trend. For instance, deviation takes place for large shear strains due to formation of infilling materials. The overall effect is that permeability was bounded by a maximum value. This effect may justify the inclusion in the model of a maximum hydraulic aperture. 

Fracture infill material such as secondary minerals and clays can have higher sorption coefficients than the original rock minerals... 

The information gathered by the scanline method can be supplemented with data from orientated cores from drillholes. The value of data on discontinuities gathered from orientated cores from drillholes depends in part on the quality of the rock concerned, in that poor-quality rock is likely to be lost during drilling. However, it is impossible to assess the persistence, degree of separation or the nature of the joint surfaces. What is more, infill material, especially if it is soft, is not recovered by the drilling operations. 

Fracture-infill material from flowing zones (Milodowski et al. 1995). These samples represent the surfaces in direct contact with the groundwater flowing through the fracture... 

Of the radioelements studied, plutonium and uranium(IV) are most sensitive to the presence of organic materials. Thorium is least sensitive thorium sorption onto some rock types is completely unaffected by organic material (e.g. fracture infill material shown in Fig. 9). 

Sub-grade the material at formation level after excavating or infilling ... 

In 1980 the Consumer Protection Act (15) required manufacturers to take reasonable steps to ensure that fabric -soft infill composites of domestic furniture resisted the cigarette test of BS5852 Part 1. These regulations did not apply to rouchings, trims to seat platforms etc. but only to the primary upholstery composites. The Consumer Protection Amendment of 1983 required specified children s furniture containing cellular materials had to resist Source 5 of BS 5852 Part 2. (16)... 

The infill deposits and the associated heavily leached lime-rock were generally found to extend from elevation +0 to +60 down to elevations from +25 to +35. It is in these areas that the supporting character of the foundation materials was suspect, leading to the use of chemical grouting as a supplement to the scheduled cement grout foundation treatment. 

Comparison of the N and qc values obtained in the grouted materials with results of similar tests conducted before grouting indicated substantial improvement in the penetration resistance had been obtained by grouting. The average N value of the infill and decomposed limerock increased from 0 to 25 blows per foot. The results indicate that for the loosest infill and softest limerock deposits, an N value of 30 blows per foot should be readily achieved during production grouting. 

Inorganic sediment is supplied by erosion of material from exposed areas of high relief, and can be transported a considerable distance to the area of deposition. The composition of this detrital (or clastic) material varies, but aluminosilicate minerals are usually important. There are also biogenic sediments, resulting from the remains of organisms (e.g. calcareous and siliceous tests, peat) and chemical sediments formed by precipitation of minerals from solution (e.g. evaporites, some limestones and authi-genic infills of pores by quartz and calcite cements).
