However, for heavy atom-free and/or metal-free guests, a long-lived T 1 at RT generally requires the host molecules to have a considerably greater T 1 than the guests to significantly suppress the k q (RT) (Hirata et al., 2013; Totani et al., 2013).

The architecture of long-lived fault zones: insights from ...

The distribution of deformed rocks within fault zones (fault zone architecture) provides a first-order control on the style (e.g., viscous creep vs. seismic rupture) and distribution of deformation (Sibson 1977, 1983; Holdsworth et al. 2001; Faulkner et al. 2010).The study of exhumed fault zones in the field allows characterisation of fault zone architecture (e.g., …

This work introduces a novel way to obtain catalytically competent oxyferryl species for two different dye-decolorizing peroxidases (DyPs) in the absence of H2O2 or any other peroxide by simply applying a reductive electrochemical potential under aerobic conditions. UV-vis and resonance Raman spectroscopies show that this method yields long-lived compounds II and I …

[5] Rocks recovered from Hole 504B reveal a complex multistage alteration history (see reviews in [Alt et al., 1996a; Alt et al., 1996c]).Alteration is most intense in brecciated lithologies and along flow boundaries and fractures but is minor in massive rock. Overall, there is a transition to higher alteration temperatures and lower water-to-rock ratios with increasing depth.

Detection of Silica-Rich Deposits on Mars

Opaline silica deposits are an indicator of past aqueous activity. Some regions of Mars exhibit a thermal infrared spectral signature that has been interpreted to result from coatings of amorphous silica on rocks (1, 2), although this interpretation is not unique ().Results from the Mars rover Opportunity have suggested that opaline silica could be present in sulfate-rich sedimentary …

Indium Phosphide InP - Wafer Export

Indium Phosphide InP is a semiconductor, crystallized in face-centered cubic structure, which we commonly name zincblende. It has the same structure as most of the III-V semiconductors. This material is characterized by long-lived optical phonons, one of the longest of any zincblende´s compound.

Riesling - Wikipedia

Riesling has a long history, and there are several written references to the variety dating from the 15th century, although with varying orthography. The earliest of these references ("Rüssling") is from 1402 in the city of Worms, Germany. Another early mention dates from March 13, 1435, when the storage inventory of Count John IV of Katzenelnbogen in Rüsselsheim (a small …
