Particles strongly adhering

The bio-briquettes are formed under high compressive force. Because of this, the desulfurizing agent and the coal particles strongly adhere to each other, and they effectively react during combustion. With the addition of a desulfurizing agent at a ratio of approximately 1.2 2 of Ca/S, 60%-80% of the sulfur in the coal is fixed in the ash. 

One of the general understanding about the carbon reinforcement of rubbers, which is vaguely understood but widely accepted, is to consider such a system where well-dispersed and discontinuously connected carbon particles are strongly adhered to the matrix cross-linked rubber. 

Rinse the plated reaction vessel once with sample buffer to remove any loose particles of Iodogen that may not be strongly adhered to the surface of the glass. 

Use any and all options for post-CMP cleaning. Keep particles from adhering more strongly than they already are, and remove them as quickly as possible. Once they are removed they must be transported away from the wafer surface as quickly and efficiently as possible to minimize redeposition. 

The same experimental group continued the research (61) by adsorption of carbon nanotubes onto both PS and PMMA particles in the same method, with four different surfactants. Finally, the prepared PS microspheres with adsorbed nanotubes were sonicated in deionised water to test the durability of their association. It was found that individual tubes remain strongly adhered to the PS microspheres surfaces even after exposition to ultrasound. 

A region of loosely bonded ash particles then built upon the more strongly adherent droplets. These particles were principally alumino-silicates, often containing some amounts of most of the... 

Under certain circumstances and/or in specific environments, self-assembly or chemical modification (e.g., doping) of nanoparticles may occur, yielding materials with new properties or defined shape and structure (below). Nanosized particles touching any kind of substrate will also strongly adhere to the surface of the solid and can not be easily removed, which may be desirable or detrimental (below). 

If the grinding process takes place in an inert atmosphere, there will be a strong tendency for the particles to adhere to one another — the caking of dry powders is a common problem in practice. 

The results can be understood in terms of the forces between rubbery swollen polystyrene. As the layers approach, there is a van der Waals attraction, but the adsorbed particles then press into each other to give the repulsion (Fig. 6.24). The polymer is too strongly adherent for the adsorbed layer to be squeezed out by the compressive force. 

The question of what happens when a bunch of particles comes together was asked by Newton, who found the process diffieult. Yet if aU particles adhere strongly as described above, they should leap into contact, then deform and squash closer to each other as a result of molecular adhesion. It is a paradox that particles which adhere sttongly do not do this. Instead they form weak, loose treelike structures because each particle sticks where it touches, as shown in Fig. 9.19(a). This instant adhesion therefore prevents good compaction, which can only be achieved if the particles do not adhere strongly but can wander around to find dense close-packing positions. Fig. 9.19(b). 

Alumina layers are strongly adhering, self-healing, and represent a perfect, compatible grounding for the washcoated layer of alumina particles that, finally, serves as the actual support for the catalyst [23],... 

Here clay is proved to be high-modulus lamellar particles that strongly adhere to the rubber latex leading to excellent reinforcement. A lot of scope exists... 

The conventional concentration procedure in SdFFF consists of two steps the feeding (or concentration) and the separation (or elution) step. In the feeding step, the diluted samples are fed into the column with a small flow velocity while the channel is rotated at a high field strength to ensure the apparent adhesion of the total number of the colloidal particles at the beginning of the channel wall as a consequence of the particles strong retention. In the separation step, the field is reduced and the flow rate is increased to ensure the total release and the consequence elution of the adherent dilute particles. 

The next step in the synthesis of supported metal catalysts via dendrimers is the immobilization of dendrimer-metal nanocomposites onto a solid support. An array of techniques exists for achieving this task. Wet impregnation and sol-gel incorporation of dendrimer-metal nanocomposites may lead to strongly adhered metal particles. Other techniques, such as functionalization of the support to facilitate dendrimer growth or adhesion, provide a route for deposition of empty dendrimers that can subsequently undergo complexation with metal precursors to form dendrimer-metal complexes and eventually zerovalent nanoparticles. Whereas the complexation and reduction phases of catalyst synthesis via dendrimers can be fairly complicated, most methods of dendrimer deposition are rather straightforward.
