Order-to-Disorder Transition and Hydrogen Bonding in the Jahn-Teller Active NHCrF Fluoroperovskite.

Large quantities of high-purity NHCrF have been synthesized using a wet-chemical method, and its structural chemistry and magnetic properties are investigated in detail for the first time. NHCrF is a tetragonal fluoroperovskite that displays an ordering of the ammonium (NH) groups at room temperature and C-type orbital ordering. The ammonium groups order and display distinct signs of hydrogen bonds to nearby fluoride anions by buckling the Cr-F-Cr angle away from 180°.

Comprehensive interrogation of gene lists from genome-scale cancer screens with oncoEnrichR.

Genome-scale screening experiments in cancer produce long lists of candidate genes that require extensive interpretation for biological insight and prioritization for follow-up studies. Interrogation of gene lists frequently represents a significant and time-consuming undertaking, in which experimental biologists typically combine results from a variety of bioinformatics resources in an attempt to portray and understand cancer relevance. As a means to simplify and strengthen the support for this endeavor, we have developed oncoEnrichR, a flexible bioinformatics tool that allows cancer researchers to comprehensively interrogate a given gene list along multiple facets of cancer relevance.
