More recent developments show that honeycomb structures are also advantageous in applications involving nanohole arrays in anodized alumina, microporous arrays in polymer thin films, activated carbon honeycombs, and photonic band gap honeycomb structures.

It was then suggested that " hydrated microporous Si could be a bioactive form of the semiconductor and suggest that Si itself should be seriously considered for development as a material for widespread in vivo applications ."
33.
Zeolites are the aluminosilicate members of the family of microporous solids known as " molecular sieves " mainly consisting of Si, Al, O, and metals including Ti, Sn, Zn, and so on.
34.
The weather hampered the work initially, but the application of a modern microporous paint, designed to withstand normal movement of the timber and yet remain waterproof, was completed in time for the lift-on.
35.
Much work since the 1960s focused on overcoming the gas exchange handicap of the membrane barrier, leading to the development of high-performance microporous hollow-fibre oxygenators that eventually replaced direct-contact oxygenators in cardiac theatres.
36.
Fine ground calcium carbonate ( GCC ) is an essential ingredient in the microporous film used in diapers and some building films as the pores are nucleated around the calcium carbonate particles during the manufacture of the film by biaxial stretching.
37.
Such a process would not be possible with zeolites or other microporous crystalline oxide-based materials because of the harsh conditions typically used for their synthesis ( e . g ., calcination at high temperatures to remove organic templates ).
38.
The separator itself may be a polymer, such as a microporous film of polyethylene ( PE ) or polypropylene ( PP ); thus, even when the cell has a liquid electrolyte, it will still contain a " polymer " component.
39.
If anodization in an aqueous solution is used to form microporous silicon, the material is commonly treated in ethanol immediately after fabrication, to avoid damage to the structure that results due to the stresses of the capillary effect of the aqueous solution.
40.
As sensitive layers, mostly non-selective measuring polymers are used which sort the analytes according to size ( the so-called molecular sieve effect when using microporous polymers ) or according to polarity ( e . g . functionalized polydimethylsiloxanes ).
