Boron Clusters as Highly Stable Magnesium‐Battery Electrolytes

Boron clusters are proposed as a new concept for the design of magnesium‐battery electrolytes that are magnesium‐battery‐compatible, highly stable, and noncorrosive. A novel carborane‐based electrolyte incorporating an unprecedented magnesium‐centered complex anion is reported and shown to perform well as a magnesium‐battery electrolyte. This finding opens a new approach towards the design of electrolytes whose likelihood of meeting the challenging design targets for magnesium‐battery electrolytes is very high. Ein b(o)rillantes Konzept : Ein Elektrolyt mit einem Magnesium‐zentrierten Komplexanion wurde für den Einsatz in wiederaufladbaren Magnesiumbatterien entwickelt. Das Carboranylmagnesiumhalogenid (siehe Struktur; B lila, C weiß, Cl grün, O rot, Mg orange) war mit Magnesiummetall‐Anoden kompatibel und zeigte an verschiedenen Nichtedelmetall‐Elektroden eine bemerkenswerte oxidative Stabilität (3.2 V gegen Mg).Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/106656/1/3237_ftp.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/106656/2/ange_201310317_sm_miscellaneous_information.pd

A solvent-free regioselective iodination route of ortho-carboranes

Tetraiodo-ortho-carborane based X-ray contrast agents can be readily prepared in a high yield, fast, clean, regioselective fashion by a solvent-free reaction of ortho-carboranes with iodine in sealed tubes.Vaca Puga, A.; Teixidor, F.; Kivekas, R.; Sillanpaa, R.; Viñas, C.

Single-Species Microarrays and Comparative Transcriptomics

BACKGROUND: Prefabricated expression microarrays are currently available for only a few species but methods have been proposed to extend their application to comparisons between divergent genomes. METHODOLOGY/PRINCIPAL FINDINGS: Here we demonstrate that the hybridization intensity of genomic DNA is a poor basis on which to select unbiased probes on Affymetrix expression arrays for studies of comparative transcriptomics, and that doing so produces spurious results. We used the Affymetrix Xenopus laevis microarray to evaluate expression divergence between X. laevis, X. borealis, and their F1 hybrids. When data are analyzed with probes that interrogate only sequences with confirmed identity in both species, we recover results that differ substantially analyses that use genomic DNA hybridizations to select probes. CONCLUSIONS/SIGNIFICANCE: Our findings have implications for the experimental design of comparative expression studies that use single-species microarrays, and for our understanding of divergent expression in hybrid clawed frogs. These findings also highlight important limitations of single-species microarrays for studies of comparative transcriptomics of polyploid species
