A directional freeze-drying (DFD) technique is introduced to fabricate PVDF composites embedded with MoS2nanosheets (NSs).The DFD process promotes the vertical alignment of MoS2NSs within the PVDF matrix, enhancing 尾-phase formation.The composite achieves a 尾-phase content of 86.28% and a ...
In summary, a vertically aligned channel structure of ultralightweight graphene foam is prepared using a single absorbing agent GNPs, directional freezing, and freeze-drying methods. It has been demonstrated that the regulation of ice crystals during freezing and sublimation leads to the formation of...
This invention relates to a method and apparatus for freezing biomaterials such as spermatazoa, fertilized ova, and the like in a controlled manner and/or for freeze drying materials in a continuous process. Other materials may likewise be frozen. The apparatus is readily adapted for use with ...

Directional freeze-drying is considered to regulate the structure of nanocellulose aerogels with special performances. In this work, TEMPO-oxidized cellulose nanofiber aerogels with high porosity (>?99.5%) and low density (~?7?mg/cm3) were produced by different freeze-drying methods. The effects ...
