Nanoscale Reference and Test Materials for the Validation of Characterization Methods for Engineered Nanomaterials – Current State, Limitations and Needs
Engineered nanomaterials (NMs) of different material composition, morphology, and surface chemistry are widely used in material and life sciences. For NM quality control and risk assessment, NM key properties must be characterized with validated methods, requiring reference materials (RMs).
Salt-In-Presalt Electrolyte Design for High-energy Sodium Batteries
Our present work introduces a new electrolyte design named “Salt-In-Presalt” (SIPS). This strategy maximizes the fluorinated anion functions at a low salt concentration and promotes inorganic electrolyte-electrode interphases to realize long-cycle performance for high-energy sodium batteries.
New Battery Interphase Technology: Electrophile Reduction Strategy
Our work presents a new interphase chemistry in which reductive electrophiles gain electrons and cations from solid-state electrolytes upon contact, forming layers on the materials' surfaces, which enhances their electrochemical stability and offers adaptable solutions for other battery materials.
Isolation of a planar π-aromatic Bi5– ring in a cobalt-based inverse sandwich-type complex
Monocyclic aromatic molecules are well-known in organic chemistry and for coordination chemistry. In contrast, isoelectronic cycles comprising (semi)metal atoms only are much rarer. We present Bi5−, the so far elusive heaviest analogue of (C5H5)− which we trapped in an inverse-sandwich-type complex.

From pore to process: an industrially promising application for MOFs in separating the most potent greenhouse gas
SF6/N2 separation is crucial for sustainable development. Here, we prepared low-cost and robust MOF composite pellets and established a vacuum temperature swing adsorption process with both high recovery and high purity of SF6.
