31/7/2020· SEM images were taken from the cross section of 1-cm height parallel to the cold surface. ( A to D ) When freezing on the homogeneously hydrophilic and hydrophobic copper substrates, the ice crystals nucleate simultaneously over the surfaces and grow without a preferred direction, resulting in a short-range lamellar structure that contains various randomly oriented domains.

Cellular ceramics are a class of highly porous materials that covers a wide range of structures, such as foams, honeycos, interconnected rods, interconnected fibres, interconnected hollow spheres. Recently, there has been a surge of activity in this field, because these innovative materials have started to be used as components in special and advanced engineering appliions.
Glass-ceramics have an amorphous phase and one or more crystalline phases and are produced by a so-called "controlled crystallization", which is typically avoided in glass manufacturing. Glass-ceramics often contain a crystalline phase which constitutes anywhere from 30% [m/m] to 90% [m/m] of its composition by volume, yielding an array of materials with interesting thermomechanical properties.

Silicon carbide (SiC) ceramics have been widely used for microelectronics, aerospace, and other industrial fields due to their excellent chemical stability and thermal tolerance. However, hard machinability and low machining precision of SiC ceramics are the key limitations for their further appliions. To address this issue, a novel method of underwater femtosecond laser machining was
