Snow Crystal Habit Changes Explained by Layer Nucleation
Abstract Critical supersaturations have been measured for the vapor growth of ice crystals on both the basal and prism faces between −16° and −0.4°C. The values are low: approximately constant atExpand
Sublimation of Ice Crystals
Abstract Recent experiments on the sublimation of single crystals of ice in an atmosphere of air indicate that the sublimation rate is diffusion limited and initially solid prismatic crystals evolveExpand
Growth mechanisms to explain the primary and secondary habits of snow crystals
Abstract By estimating the diffusion field adjacent to growing snow crystals and using a variety of ice crystal growth data, it is shown that most observations of snow crystal habits above -22°C areExpand
Branch Growth and Sidebranching in Snow Crystals
Why do some snow crystals have branches with many sidebranches, whereas other crystals have no sidebranches? To answer this question and gain an understanding of other common features of snow crystalExpand
Air pockets and secondary habits in ice from lateral-type growth
Abstract. Often overlooked in studies of ice growth is how the crystal faces grow laterally. This paper explores the implications of such lateral-type growth and how it may explain air pockets andExpand
Repeasantisation in The United States
This article adopts Van der Ploeg's theory of repeasantisation to demonstrate that, even in the largely industrialised agricultural state of Kansas, USA, there are unexpected interstices withinExpand
A new technique for growing crystals from the vapor
A new method for growing single crystals with sensitive control of supersaturation and minimal influence from foreign surfaces is described.
Heat conduction problems in crystal growth from the vapor
Abstract When a crystal is grown or evaporated on a substrate, temperature gradients are set up in the crystal. The surface temperature of the crystal becomes non-uniform and differs from theExpand
Gold-Catalyzed Oxidation of Propargylic Ethers with Internal C-C Triple Bonds: Impressive Regioselectivity Enabled by Inductive Effect.
Inductive perturbations of C-C triple bonds are shown to dictate the regiochemistry of gold-catalyzed oxidation of internal C-C triple bonds in the cases of propargylic ethers, resulting in highlyExpand
