Identification of Imitation Cheese and Imitation Ice Cream Based on Vegetable Fat Using NMR Spectroscopy and Chemometrics

International Journal of Food Science, 2013
Vegetable oils and fats may be used as cheap substitutes for milk fat to manufacture imitation cheese or imitation ice cream. In this study, 400 MHz nuclear magnetic resonance (NMR) spectroscopy of the fat fraction of the products was used in the context

Formation of Hydrogen, Oxygen, and Hydrogen Peroxide in Electron Irradiated Crystalline Water Ice

, 2005
Water ice is abundant both astrophysically, for example in molecular clouds, and in planetary systems. The Kuiper belt objects, many satellites of the outer solar system, the nuclei of comets and some planetary rings are all known to be water-rich ...

HDO Ice Detected toward an Isolated Low-mass Protostar with JWST

The Astrophysical Journal Letters
Water is detected in environments representing every stage of star and solar system formation, but its chemical evolution throughout these stages remains poorly constrained.

Effect of Regolith–Ice Stratigraphy and Laser Weathering on Ultraviolet–Visible–Near-infrared Detection of Lunar Water Ice

The Planetary Science Journal
Investigating volatiles is critical for understanding their delivery to the Moon and for their potential as a resource for sustained lunar exploration. Water ice and potentially other volatiles are known to exist in and proximal to permanently shadowed ...

Hexagonal ice : Single crystalline hexagonal ice studied through surface-specific vibrational spectroscopy

, 2017
In this thesis, we study the surface of water in its liquid and solid state. We investigate (i) an aqueous system where a model membrane interacts with amphiphilic dendrimers and (ii) single crystalline ice. We present a molecular scale description of both systems.

Observation of Ice-Like Two-Dimensional Flakes on Self-Assembled Protein Monolayer without Nanoconfinement under Ambient Conditions

Nano-Micro Letters
Highlights The two-dimensional (2D) ice-like water layers are formed on the self-assembled monolayers (SAMs), which support the physisorption of Cytochrome C (Cyt C) protein layer under ambient conditions, without the need for nanoconfinement.

Methane, ammonia, and their irradiation products at the surface of an intermediate-size KBO? A portrait of Plutino (90482) Orcus

, 2010
Orcus is an intermediate-size 1000km-scale Kuiper Belt Object in 3:2 mean-motion resonance with Neptune, in an orbit very similar to that of Pluto. We present visible and near-infrared photometry and spectroscopy obtained with the Keck 10m-telescope and ...

Hidden force opposing ice compression

, 2012
Coulomb repulsion between the unevenly-bound bonding and nonbonding electron pairs in the O:H-O hydrogen-bond is shown to originate the anomalies of ice under compression.

JWST Spectrophotometry of the Small Satellites of Uranus and Neptune

The Planetary Science Journal
We use 1.4–4.6 μ m multiband photometry of the small inner Uranian and Neptunian satellites obtained with the James Webb Space Telescope’s near-infrared imager NIRCam to characterize their surface compositions.

Dissolved organic carbon loss from Yedoma permafrost amplified by ice wedge thaw

Environmental Research Letters, 2013
Pleistocene Yedoma permafrost contains nearly a third of all organic matter (OM) stored in circum-arctic permafrost and is characterized by the presence of massive ice wedges.
