This study focuses primarily on ice nucleation from water vapor (i.e., deposition mode nucleation) at cold temperatures (233 to 248 K). We have chosen feldspar because it has recently been …

WebThe MWCNTs were seen to act as heterogeneous nucleating surfaces (oriented shish structures) for the epitaxial growth of PET crystallites (kebabs) giving an oriented NHSK morphology. In contrast, the neat PET homopolymer showed the sporadic nucleation of a classic unoriented lamellar structure under the same isothermal crystallization conditions. Web5 Apr 2024 · Nucleation is a fundamental physical process, however it is a long-standing issue whether completely homogeneous nucleation can occur.
