The universe is molecularly rich, comprising from the simplest molecule (H2) to complex
organic molecules (eg, CH3CHO and NH2CHO), some of which of biological relevance (eg …

Dust grains play a central role in the physics and chemistry of cosmic environments. They
influence the optical and thermal properties of the medium due to their interaction with stellar …

Amorphous solid water (ASW) is found on icy dust grains in the interstellar medium (ISM), as
well as on comets and other icy objects in the outer solar system. The optical properties of …

Infrared multiple‐angle incidence resolution spectrometry (IR‐MAIRS) is a recently
developed spectroscopic technique that combines oblique incidence transmission …

Small hydrocarbons are an important organic reservoir in protostellar and protoplanetary
environments. Constraints on desorption temperatures and binding energies of such …

The need to characterize ices coating dust grains in dense interstellar clouds arises from the
importance of ice morphology in facilitating the diffusion and storage of radicals and reaction …

We use an ultra-high vacuum cryogenic atomic force microscope to investigate the surface
morphology of amorphous solid water (ASW) prepared by oblique deposition of water vapor …

In the interstellar medium (ISM), the formation of complex organic molecules (COMs) is
largely facilitated by surface reactions. However, in cold dark clouds, thermal desorption of …

The degree of porosity in interstellar dust-grain material is poorly defined, although recent
work has suggested that the grains could be highly porous. Aside from influencing the …

Experimental measurements on the thermal and nonthermal behavior of water and other
simple molecules, including organic compounds such as methanol and benzene, on model …
