The protein product of a gene (inaZ) responsible for ice nucleation by Pseudomonas syringae S203 has been identified and purified after overexpression in Escherichia coli. The amino acid composition and the N-terminal sequence of the purified, denatured protein corresponded well with that predicted from the sequence of the inaZ gene. The product of inaZ was also found to be the major component ...

It has long been known that ice nucleation usually proceeds heterogeneously on the surface of a foreign body. However, little is known at the microscopic level about which properties of a material determine its effectiveness at nucleating ice. This work focuses on the long standing, conceptually simple, view on the role of a good crystallographic match between bulk ice and the underlying substr...

This paper focuses on chemical characterization of ice-nucleating particles and the results from different sampling techniques are compared. The scientific results are in-teresting and the comparison of different techniques is necessary. The results from this paper are an important contribution to the fields of ice nucleation and aerosol chem-istry; however, I can only recommend this paper for ...

Ice nucleating particles active at −8 ◦C or warmer (INP−8) are produced by plants and by microorganisms living from and on them. Laboratory studies have shown that large numbers of INP−8 are produced by decaying leaves. At three widely dispersed locations in Northwestern Eurasia, we saw, from an analysis of PM10 filter samples, that seasonal median concentrations of INP−8 in the boundary layer ...

Abstract. Mineral dust and sea spray aerosol represent important sources of ice-nucleating particles (INPs), the minor fraction able to trigger cloud ice crystal formation and, consequently, influence multiple climate-relevant properties including lifetime, radiative precipitation initiation efficiency. is considered dominant INP source in many parts world due its nucleation efficiency sheer ab...
