The near-infrared spectrum of Triton reveals ices of nitrogen, methane, carbon monoxide, and carbon dioxide, of which nitrogen is the dominant component. Carbon dioxide ice may be spatially segregated from the other more volatile ices, covering about 10 percent of Triton's surface.

Annual Review of Physical Chemistry, 2017
Ice is a fundamental solid with important environmental, biological, geological, and extraterrestrial impact. The stable form of ice at atmospheric pressure is hexagonal ice, Ih. Despite its prevalence, Ihremains an enigmatic solid, in part due to challenges in preparing samples for fundamental studies.

Surface Trapped Excess Electrons on Ice
Physical Review Letters, 2005Local trapping of excess electrons at the surface of solid water systems has recently been observed in large water clusters and at the ice/vacuum interface. The existence of stable surface-bound states for the excess electron may have important implications in atmospheric chemistry, electrochemistry, and radiation physics.

The present theories of surface premelting are based on the assumed mechanism whereby a liquid layer is formed because the free energy of the surface is thus minimized. It is shown experimentally here that this mechanism is not possible in the case of ice, for which surface melting below 0 °C is, however, well documented. A mechanism of surface melting,

Ice nanoclusters at hydrophobic metal surfaces
Nature Materials, 2007Studies of the structure of supported water clusters provide a means for obtaining a rigorous molecular-scale description of the initial stages of heterogeneous ice nucleation: a process of importance to fields as diverse as atmospheric chemistry, astrophysics and biology.

As record-high temperatures in triple digits bake much of the U.S. Midwest and parts of the East Coast this summer, most people are consumed with figuring out how to beat the heat.

Surface-induced ferroelectric ice
Technical Digest. Summaries of Papers Presented at the International Quantum Electronics Conference. Conference Edition. 1998 Technical Digest Series, Vol.7 (IEEE Cat. No.98CH36236), 2002Summary form only given. Can ice be ferroelectric! This question has long attracted much attention. In crystalline ice, water molecules are held together by tetrahedralhydrogen bonding. The molecular orientations at the lattice points should obey the ice rules, which require that each molecule donate two protons to two of the attached water molecules ...

In this review, we summarize the available experimental data from recently developed molecular level techniques on the surface structure, surface premelting layer thickness, and friction of ice. We conclude that surface premelting of ice is responsible for the unique surface properties of the important substance.
