Isocyanogen formation in the cold interstellar medium [PDF]
A&A 625, A91 (2019), 2019 Cyanogen (NCCN) is the simplest member of the dicyanopolyynes group, and has been proposed as a major source of the CN radical observed in cometary atmospheres. Although not detected through its rotational spectrum in the cold interstellar medium, this very stable species is supposed to be very abundant.

How to study basement membrane stiffness as a biophysical trigger in prostate cancer and other age-related pathologies or metabolic diseases [PDF]
, 2016 Here we describe a protocol that can be used to study the biophysical microenvironment related to increased thickness and stiffness of the basement membrane (BM) during age-related pathologies and metabolic disorders (e.g. cancer, diabetes, microvascular

Frontiers in Plant Science, 2020 Plant transmembrane proteins (TMPs) are essential for normal cellular homeostasis, nutrient exchange, and responses to environmental cues. Commonly used bottom–up proteomic approaches fail to identify a broad coverage of peptide fragments derived from ...

Riboproteomics: A versatile approach for the identification of host protein interaction network in plant pathogenic noncoding RNAs. [PDF]
PLoS ONE, 2017 Pathogenic or non-pathogenic small (17 to 30 nt) and long (>200 nt) non-coding RNAs (ncRNAs) have been implicated in the regulation of gene expression at transcriptional, post-transcriptional and epigenetic level by interacting with host proteins ...

A New Monomeric Interpretation of Intrinsic Optical Bistability Observed in Yb3+ - Doped Bromide Materials [PDF]
Chem. Phys. Lett. 381, 163 (2003), 2003 We present a mechanism able to show intrinsic bistable behaviour involving single Yb3+ ions embedded into bromide lattices, in which intrinsic optical bistability (IOB) has been observed. The mechanism is based on the experimentally found coupling between the Yb3+ ion and the totally symmetric local mode of vibration of the [YbBr6]3- coordination unit.

UV photodissociation of methyl bromide and methyl bromide cation studied by velocity map imaging [PDF]
Journal of Chemical Physics 130 (2009) 034304, 2009 We employ the velocity map imaging technique to measure kinetic energy and angular distributions of state selected CH3 (v2=0,1,2,3) and Br (2P3/2,2P1/2) photofragments produced by methyl bromide photolysis at 215.9 nm. These results show unambiguously that the Br and Br* forming channels result in different vibrational excitation of the umbrella mode ...
