The mine was subsequently acquired by the Calleja Group transport company primarily as a dump for green waste. By 1994 the Calleja Group had acquired ownership of a methodology to create densified coal. The company invested in the application of Maddingley brown coal as a soil conditioner and natural fertiliser replacement for super phosphate, and the development of bench test equipment to produce batch samples of densified coal. Around 1997 the working technology to achieve densified coal became known as the Coldry Process.

In addition to improved mechanical properties, less SiC needs to be added when using this method, which limits the pathways for oxygen to diffuse into the material and react. Although addition of additives such as SiC can improve densification of UHTC materials, these additives lower the maximum temperature at which UHTCs can operate due to the formation of eutectic liquids. The addition of SiC to ZrB2 lowers the operating temperature of ZrB2 from 3245 °C to 2270 °C. Hot pressing is a popular method for obtaining densified UHTC materials that relies upon both high temperatures and pressures to produce densified materials.

Vancouver is located on the West Coast of Canada. It is the largest city in the region with an increasing population in the metropolitan area. Apart from the highly densified central business district (CBD), more efficient land use strategy was needed in less dense suburban neighbourhoods. The urban development in Vancouver started in the 19th century mainly shaped by automobile-based infrastructural development.

Later on, they found marine clay mixed with seawater even in the deeper underground. Geotechnical problems posed by marine clay can be handled by various ground improvement techniques. Marine clay can be densified by mixing it with cement or similar binding material in specific proportions. Marine clay can be stabilised using wastes of various industries like porcelain industry and tree-cutting industries.

The material is aspirated (sucked in) and held on the filter drum by a vacuum, where it is drawn in the space between the filter and pressure drums. The combination of vacuum and pressure causes a deaerating and densification of the product. At the end of the densification process, the densified product is stripped off the filter drum by knives so it can leave the machine.

The first generator was commissioned on 8 January 1955, the second and last on 1 April 1955. On 1 July 1955 the entire project was complete. The Great Alaska earthquake in March 1964 caused significant damage to the dam, particularly the water intake for the power plant. The intake shifted towards the lake and frozen alluvium beneath and near the dam's spillway densified, creating voids.

Processes which remove water from brown coal reduce the risk of spontaneous combustion to the same level as black coal, increase the calorific value of brown coal to a black coal equivalent fuel, and significantly reduce the emissions profile of 'densified' brown coal to a level similar to or better than most black coals.George, A.M..

After the initial molding, the feedstock binder is removed, and the metal particles are diffusion bonded and densified to achieve the desired strength properties. The latter operation typically shrinks the product by 15% in each dimension. The metal injection molding market has grown from US$9 million in 1986, to US$382 million in 2004 to more than US$1.5 billion in 2015. A related technology is ceramic powder injection molding, leading to about US$2 billion total sales.

SiAlON gear (right) prepared from a billet (left) by forging at 1200 °C within 2 seconds. SiAlONs are produced by first combining a mixture of raw materials including silicon nitride, alumina, aluminium nitride, silica and the oxide of a rare-earth element such as yttrium. The powder mix is fabricated into a "green" compact by isostatic powder compaction or slipcasting, for example. Then the shaped form is densified, typically by pressureless sintering or hot isostatic pressing.

Intelligent urbanism recognizes that there is always a spillover of population from the city into the region, and that population in the region moves into the city for work, shopping, entertainment, health care and education. With thoughtful planning the region can take pressure off of the city. Traditional and new settlements within the urban region can be enhanced and densified to accommodate additional urban households. There are many activities within the city, which are growing and are incompatible with urban habitat.

Multiple colored swatches of non-woven fabric Nonwoven fabric is a fabric-like material made from staple fibre (short) and long fibres (continuous long), bonded together by chemical, mechanical, heat or solvent treatment. The term is used in the textile manufacturing industry to denote fabrics, such as felt, which are neither woven nor knitted. Some non-woven materials lack sufficient strength unless densified or reinforced by a backing. In recent years, non- wovens have become an alternative to polyurethane foam.

Constrained Delaunay triangulations are also useful for minimizing the size of a TIN, since they have fewer nodes and triangles where breaklines are not densified. The TIN model was developed in the early 1970s as a simple way to build a surface from a set of irregularly spaced points. The first triangulated irregular network program for GIS was written by W. Randolph Franklin, under the direction of David Douglas and Thomas Peucker (Poiker), at Simon Fraser University in 1973.Franklin, W. R. (1973).

The final product is the remaining solid, dry, blackened material that is referred to as torrefied biomass or bio-coal. During the process, the biomass typically loses 20% of its mass (bone dry basis) and 10% of its heating value, with no appreciable change in volume. This energy (the volatiles) can be used as a heating fuel for the torrefaction process. After the biomass is torrefied it can be densified, usually into briquettes or pellets using conventional densification equipment, to increase its mass and energy density and to improve its hydrophobic properties.

Around the station Ober-Eschbach emerged in recent years, a densified residential area, which exploits the convenient transport links. The following station Gonzenheim has been the terminus of the Homburger line since the changeover to subway operation. The formerly from here in the Homburg city center continuing tram line led through narrow city streets, in which a subway operation on the surface was not possible. The terminus is one of the many long-term temporaries of the Frankfurt subway, because since its commissioning in 1971 is planned to extend the U2.

Torrefied and densified biomass has several advantages in different markets, which makes it a competitive option compared to conventional biomass wood pellets. Higher energy density: :An energy density of 18–20 GJ/m³ — compared to the 26 to 33 gigajoules per tonne heat content of natural anthracite coal — can be achieved when combined with densification (pelletizing or briquetting) compared to values of 10–11 GJ/m³ for raw biomass, driving a 40–50% reduction in transportation costs. Importantly, pelletizing or briquetting primarily increases energy density. Torrefaction alone typically decreases energy density, though it makes the material easier to make into pellets or briquettes.

Abnormal or discontinuous grain growth leads to a heterogeneous microstructure where a limited number of grains grow much faster than the rest. Abnormal or discontinuous grain growth, also referred to as exaggerated or secondary recrystallisation grain growth, is a grain growth phenomenon through which certain energetically favorable grains (crystallites) grow rapidly in a matrix of finer grains resulting in a bimodal grain size distribution. In ceramic materials this phenomenon can result in the formation of elongated prismatic, acicular (needle-like) grains in a densified matrix with implications for improved fracture toughness through the impedance of crack propagation.

This system is not considered to be real polished concrete, as there is little physical refinement of the concrete slab. However, it does provide a similar look to polished concrete, so may be appropriate in some areas. Typically this system is referred to as a "half polish" as generally the surface is only processed through three steps of grinding (half the processing steps of a true polished concrete floor). The surface is densified so the advantages of the densifier are inherited, then a concrete sealer or a high buildup of a concrete guard is used to create a shine.

Indeed, even with the CNTs, which are strongly densified and spun, low conductance remains a problem. However, a recent paper shows that a one-decade improvement on the conductivity may be gained just by high-pressure densification of the CNT. In spite of the development of high-density CNT material the state of the art of integrated lines is still far from the 1013 cm−2 conducting walls requested by the International Technology Roadmap for Semiconductors. Nevertheless, macroscopic assemblies with diameters of tens of microns consisting of double- walled CNTs or single-walled carbon nanotubes have experimental resistivity performances of 15 μΩcm after doping, demonstrating the potential of CNTs for interconnects.

Pre Combustion Innovations Alliance A primary benefit of refined coal is the capacity to reduce the net volume of carbon emissions that is currently emitted from power generators and would reduce the amount of emissions that is proposed to be managed via emerging carbon sequestration methodologies. Refined coal technologies have primarily been developed in the United States, several similar technologies have been researched, developed and tested in Victoria, Australia, including the Densified coal technology (Coldry Process) developed to alter the chemical bonds of brown coal to create a product that is cleaner, stable (not prone to spontaneous combustion), exportable and of sufficiently high calorific value to be a black coal equivalent.

Labeyrie has proposed the idea of an astronomical interferometer where the individual telescopes are positioned in a spherical arrangement (requiring them to be positioned to a fraction of a wavelength). This geometry reduces the amount of pathlength compensation required when re-pointing the interferometer array (in fact a Mertz corrector can be used rather than delay lines), but otherwise is little different from other existing instruments. He has suggested a space-based interferometer array much larger (and complex) than the Darwin and Terrestrial Planet Finder projects using this spherical geometry of array elements along with a densified pupil beam combiner, calling the endeavor a "Hypertelescope"Laboratoire pour l’Interférométrie Stellaire et Exoplanétaire: Hypertelescope project. It might theoretically show features on Earth-like worlds around other stars.

As of 2019, SpaceX is developing a system in which a reusable first stage vehicle would transport a crewed interplanetary spacecraft to Earth orbit, detach, return to its launch pad where a tanker spacecraft would be mounted atop it, then both fueled, then launched again to rendezvous with the waiting crewed spacecraft. The tanker would then transfer its fuel to the human crewed spacecraft for use on its interplanetary voyage. The SpaceX Starship is a stainless steel-structure spacecraft propelled by six Raptor engines operating on densified methane/oxygen propellants. It is -long, -diameter at its widest point, and is capable of transporting up to of cargo and passengers per trip to Mars, with on-orbit propellant refill before the interplanetary part of the journey.

The producer of densified coal in Australia is a company based in Melbourne, Victoria called Environmental Clean Technologies Limited (ECT Limited)Environmental Clean Technologies Limited The company is publicly traded and listed on the Australian Stock Exchange (ASX). The company was listed in 2005 with the primary purpose of commercialising the Coldry Process coal-upgrading methodology first developed in the Chemical Laboratory of Melbourne University by Dr B. A. John in the 1980s. The name of the process derived from the Calleja Group, which acquired the technology in 1994 and developed the technology to pilot demonstration at Maddingley Mine, Bacchus Marsh, Victoria in 2004 before licensing the technology to ECT Limited for further commercialisation in 2005. The State of Victoria contains approximately 25% of the world's known reserves of brown coal (lignite).

Aluminium oxide can be grown as a coating on aluminium by anodizing or by plasma electrolytic oxidation (see the "Properties" above). Both the hardness and abrasion-resistant characteristics of the coating originate from the high strength of aluminium oxide, yet the porous coating layer produced with conventional direct current anodizing procedures is within a 60-70 Rockwell hardness C range which is comparable only to hardened carbon steel alloys, but considerably inferior to the hardness of natural and synthetic corundum. Instead, with plasma electrolytic oxidation, the coating is porous only on the surface oxide layer while the lower oxide layers are much more compact than with standard DC anodizing procedures and present a higher crystallinity due to the oxide layers being remelted and densified to obtain α-Al2O3 clusters with much higher coating hardness values circa 2000 Vickers hardness. Aluminium oxide output in 2005Alumina is used to manufacture tiles which are attached inside pulverized fuel lines and flue gas ducting on coal fired power stations to protect high wear areas.
