During interactions with its mammalian host, the pathogenic yeast Candida albicans is exposed to a range of stresses such as superoxide radicals and cationic fluxes. Unexpectedly, a nonbiased screen of transcription factor deletion mutants revealed that the phosphate-responsive transcription factor Pho4 is vital for the resistance of C. albicans to these diverse stresses. RNA-Seq analysis indic...

The influence of quenched disorder on the competition between ordered states separated by a first-order transition is investigated. A phase diagram with features resembling quantum-critical behavior is observed, even using classical models. The low-temperature paramagnetic regime consists of coexisting ordered clusters, with randomly oriented order parameters. Extended to manganites, this state...

In the past decades, remarkable progress has been achieved in exploration of electrocatalysts with high activity, long durability, and low cost. Among these, defective graphene (DG)-based catalysts are considered as one most potential substitutes for precious metal-based electrocatalysts. DG-based contain abundant active centers different configurations resulting from their extraordinary high-s...

A nonmetal doping strategy was exploited for the conventional La0.5Sr0.5FeO3-δ (LSF) cathode, allowing high performance proton-conducting solid oxide fuel cells (H-SOFCs). Unlike previous studies focusing on utilization of metal oxides as dopants, phosphorus, which is a element, used cation dopant LSF by partially replacing Fe ions to form new La0.5Sr0.5Fe0.9P0.1O3-δ (LSFP) compound. The H-SOFC...
