Detection of Microbes in Ice Using Microfabricated Impedance Spectroscopy Sensors [PDF]

ECS Sensors Plus, 2023
During the growth of a polycrystalline ice lattice, microorganisms partition into veins, forming an ice vein network highly concentrated in salts and microbial cells.

Observation of sublimation of ice using terahertz spectroscopy [PDF]

Royal Society Open Science, 2020
Although many studies have investigated the phase change of water, few have focused on the sublimation of ice. This study revealed that ice sublimation can be observed using terahertz (THz) spectroscopy.

Proton Ordering of Cubic Ice Ic: Spectroscopy and Computer Simulations [PDF]

The Journal of Physical Chemistry C, 2014
Several proton-disordered crystalline ice structures are known to proton order at sufficiently low temperatures, provided that the right preparation procedure is used. For cubic ice, ice Ic, however, no proton ordering has been observed so far. Here, we subject ice Ic to an experimental protocol similar to that used to proton order hexagonal ice.

Elastic Constants of Ice by Brillouin Spectroscopy [PDF]

Journal of Glaciology, 1980
AbstractBrillouin spectroscopy has been used to measure the adiabatic elastic constants of laboratory-grown pure monocrystalline ice Ih at – 3°C. The values obtained were (in units of 108 N/m2): c11 = 136.96 ±0.60, c12 = 69.66± 0.45, c13 = 56.28±0.31, c33 = 147.02±0.68, c44 = 29.59±0.15. Comparison of these values with ultrasonic measurements quoted in

Infrared spectroscopy of HCOOH in interstellar ice analogues [PDF]

Astronomy & Astrophysics, 2007
Context: HCOOH is one of the more common species in interstellar ices with abundances of 1-5% with respect to solid H2O. Aims: This study aims at characterizing the HCOOH spectral features in astrophysically relevant ice mixtures in order to interpret ...

AKARI Near Infrared Spectroscopy: Detection of H2O and CO2 Ices toward Young Stellar Objects in the Large Magellanic Cloud [PDF]

, 2008
We present the first results of AKARI Infrared Camera near-infrared spec- troscopic survey of the Large Magellanic Cloud (LMC). We detected absorption features of the H2O ice 3.05 um and the CO2 ice 4.27 um stretching mode toward seven massive young ...

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

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.

A Study of the In-Vial Crystallization of Ice in Sucrose–Salt Solutions—An Application for Through-Vial Impedance Spectroscopy (TVIS) [PDF]

Applied Sciences
Ice nucleation temperatures and associated ice growth rates are critical parameters in defining the initial ice morphology template, which governs dry layer resistance during sublimation and therefore impacts primary drying kinetics and overall process ...
