Structural Aspects of Lithium‐Ion Conduction in the Phosphidotitanate Li8TiP4 and Its Comparison With Li7+5xTa1−xP4 and Li8−xTi1−xTaxP4

Chemistry – A European Journal, EarlyView.
ABSTRACT The chemical system Li/Ti/P has previously been subject to intensive investigation. However, reliable structural data for the reported phases have remained elusive. Motivated by the growing interest in phosphorus‐based lithium‐ion conductors, we have reinvestigated the synthesis, crystal structure, and physical properties of Li8TiP4.

Mononuclear Molybdenum and Tungsten Phosphine Complexes for Catalytic Ammonia Synthesis: Development of the pentaPod Concept

ChemPhysChem, EarlyView.
The pentaPod (P5) concept unites tridentate and tripodal fragments to form molybdenum and tungsten catalytic Chatt‐type complexes for N2‐to‐NH3 reduction. Two pentaPod ligands, P5Me and P5Pln, are available with either two dimethylphosphine or phospholano (Pln) groups. The complexes enable the investigation of reactivity differences in N2 reduction and,

Arbuscular mycorrhiza in the urban jungle: Glomeromycotina communities of the dominant city tree across Amsterdam

PLANTS, PEOPLE, PLANET, EarlyView.
Trees in cities provide a great number of benefits to people and nature, but they are challenged by harsh conditions. Trees rely on helpful fungi in their roots to get essential nutrients from the soil, but we do not know which of these fungi are resistant to city landscapes.
