Gold clusters were deposited in a narrow size distribution on porous coordination polymers (PCPs) by solid grinding with volatile dimethyl Au III acetylactonate. The mean diameter could be minimized down to 1.5 nm for Al‐containing PCP. Gold clusters on PCPs showed noticeably high catalytic activity in the aerobic oxidation of alcohols.

Grinding processes for polymer matrix …

Unfortunately, the grinding of composites is a far more difficult and complicated procedure than the grinding of metals. While the later process is well-understood and can be easily controlled and optimized to enable trouble-free operations, the nature as well as the physical and mechanical properties of composites make it very difficult to achieve that goal.

Advantages of Cryo Grinding - AAAmachine, Inc.

Ultra-fine Particle Grinding. OGL's cryo grinding process produces much more finely ground particles than conventional milling methods. OGL cryo mills are able to grind many materials to 10µm average particle size or smaller. This improves the particle flow of polymers and dispersion potential for processed polymers and foodstuffs in liquid.

Production of polymer particles below 5 μm by …

Highlights Polymer particles below 5 μm are produced by wet grinding at reduced temperatures. The approach is even applicable to PEEK with high fracture toughness. Higher stirrer speed and lower temperature reduces final particle size and enhances kinetics. Appropriate choice of solvent viscosity avoids viscous dampening of bead motion.
