Near-infrared Spectroscopy for Remote Sensing of Porosity, Density, and Cubicity of Crystalline and Amorphous H2O Ices in Astrophysical Environments

The Astrophysical Journal
We present laboratory spectra of pure amorphous and crystalline H _2 O ices in the near-infrared (NIR, 1–2.5 μ m/10,000–4000 cm ^−1 ) at 80–180 K.

Electron transfer between complexes III and IV in S. cerevisiae mitochondrial membranes

FEBS Letters, EarlyView.
Mitochondrial oxidative phosphorylation in S. cerevisiae mitoplasts is limited by complex IV catalytic capacity, rather than two‐dimensional cytochrome c diffusion. At physiological cytochrome c : supercomplex ratios at salinity equivalent to that of 20 mm monovalent salt, activity is maximized, indicating that this low ionic strength accurately mimics

Ice nucleation under cirrus cloud conditions [PDF]

, 2012
Cirrus are thin upper tropospheric clouds that are composed entirely of ice particles. Due to their extensive coverage of the Earth’s surface, they have a significant impact on the Earth’s radiative balance.

Vibrational Förster transfer in ice Ih

, 2010
We have studied Förster energy transfer between O−H vibrations in H2O/D2O ice Ih using femtosecond, two-color, mid-infrared pump−probe spectroscopy.

Dependence of the Ice Formation Activity of Dioxynaphthalenes, Fluoroglucin and Silver Iodide on the Structure of the Hydrate Shells of Their Crystals

Adsorption Science & Technology, 1999
The 1 H NMR spectroscopy of frozen suspensions has been used to investigate the hydrate shells of Agl, fluoroglucin (FG) and dioxynaphthalenes (DON). It has been shown that the ice formation activity (IFA) of the above compounds may be correlated with ...

ABL kinase‐dependent phosphorylation of SH proteins promotes their direct interaction with CRK family SH2 domains

FEBS Letters, EarlyView.
CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.

Infrared Band Strengths of Dangling OH Features in Amorphous Water at 20 K

The Astrophysical Journal
Infrared (IR) spectra of vapor-deposited amorphous water at low temperatures show two weak peaks at around 3720 and 3696 cm ^−1 assigned to free-OH stretching modes of two- and three-coordinated water molecules (so-called “dangling” OH bonds ...
