Scope

Mixed anion compounds consisting of multiple anions have attracted much attention. The use of multiple anions affords unusual local coordination around a cation in an inorganic crystal, giving greater chances to impart new materials properties as compared to conventional mono-anionic oxides or nitrides. In addition, as anions of abundant elements including hydrogen, chlorine, sulfur, phosphorus, carbon are especially focus on, the mixed anion approach is unimpeded by conventional problems of resource scarcity and distribution. The concept of the mixed anion compounds may not be restricted in inorganic crystalline solids, but expand to amorphous, non-crystalline nanomaterials, organic-inorganic hybrids, and other emerging materials. We now stand at the dawn of the mixed anion age.

This conference will provide a forum for extensive discussion and exchange of information among researchers exploring new mixed anion compounds and their functions with ‘mixing’ research communities that have been divided into many narrow disciplines. The scope of the symposium will include state-of-the art methods for structural and chemical characterization such as synchrotron-based spectroscopy and diffractometry, and combined in many cases with theoretical and simulation methodologies. In addition, new methodologies for synthesis tailor-made for the mixed anion compounds will also be one of the main topics under discussion.

The conference’s scope will survey the mixed-anion materials landscape with emphasize on the following aspects:

Searches for new mixed-anion compounds with the goal to expand and tune their functionalities and electronic properties from anion control (e.g. dielectric, semiconductive, superconductive, ionic conductive, intercalation, redox, ferroelectric, ferromagnetic, thermoelectric, electrocatalytic, photocatalytic, luminescent, etc.…). Band gap and electronic structure engineering from anionic substitution. Electronic properties control based on heterostructures, interface phenomena, electrode interactions and various device prototypes demonstrations.

Advances in synthesis techniques that have enabled the development of mixed anion materials, with emphasize on more efficient and environmental friendly methods. Innovative synthesis routes for oxynitrides, oxyfluorides, oxyhydrides, …, coordination compounds, metal-organic frameworks, etc. with forms of powders, nanomaterials, bulk ceramics, glasses, thin films and single crystals.

Computational, theory, simulations, materials informatic approaches for design of new mixed anion-controlled materials and prediction of their functionalities. Theoretical concepts for novel physics and chemistry for synthetic routes, device structures, etc.

State-of-the-art techniques and challenges in the analytical and functional properties characterization for mixed anion systems, including synchrotron and neutron diffractometry and spectroscopy, transmission electron microscopy-based advanced characterization.

Applications of mixed anion materials for production, conversion and storage of energy (supercapacitor, secondary battery, fuel cell, chemical sensor, photo- and electro-catalytic reactors), electronic and optical devices (thermoelectric converter, photovoltaic cell, transparent electronics, scintillator, nonlinear optics)
