Relationship between the bandgap energy and photoluminescence properties of Pr3+-activated complex perovskite oxides by cation–nitrogen substitution
The photoluminescence properties of f–f emission-type phosphors strongly depend on the electronic structure of the host materials.
Environmentally responsible production of lime from recycled gypsum and weakly alkaline wastewater
Benefits associated the treatment of wastewater from a returnable glass bottle-washing process as applied in this study. Our result transforms wastewater treatment into resource recovery, producing lime in an environmentally responsible manner.

Yttria-stabilized zirconia (8YSZ) synthesis in a supercritical CO2-assisted process: a parametric study for achieving cubic phase stability
Supercritical CO2 solvent enables the synthesis of crystallized oxide particles with high specific surfaces. A route was developed to generate nano-structured YSZ powders which may be suitable for porous SOC electrodes or dense electrolytes.
Effect of ammonia addition on the dispersion and activity of supported copper species on porous silica–alumina hollow spheres for catalytic decomposition of nitrous oxide
In this work, we investigated the influence of ammonia addition in the immersion process of active species on the dispersion and activity of copper-supported porous hollow silica–alumina sphere catalysts for the decomposition of nitrous oxide.
Development of paste-like organic/inorganic artificial bones compatible with bone remodeling cycles, consisting of β-tricalcium phosphate, calcium sulfate hemihydrate, and poly(lactic-co-glycolic acid) particles
Schematic illustration of organic/inorganic hybrid cement with the simultaneous addition of CSH and PLGA particles.
Paper
A boron nitride–carbon composite derived from ammonia borane and ZIF-8 with promises for the adsorption of carbon dioxide
In the present study, we report the synthesis, characterization and assessment of the carbon dioxide adsorption capacity of a composite made of boron nitride and carbon.

Elucidation of the structural features and photoluminescence properties of a hydrothermally-synthesized γ-KEu(MoO4)2 microcrystal phosphor with metastable orthorhombic structure and differences in the luminescence properties by structure transition due to Y3+-dilution
Potassium europium molybdate, KEu(MoO4)2, is an intriguing material known for its efficient luminescence properties attributed to Eu3+ ions and its polymorphic nature.

Direct pseudomorphic transformation of silica from rice husk into organo-functionalized MCM-41
Highly ordered bio-sourced MCM-41 functionalized with amide derivatives of amino acids (AA) was successfully synthesized and applied for protein separation.
Preparation of Mg, Ca, or Sr-included mesoporous silica from glass bottle waste for recovery of rare earth metal elements
This paper suggests new uses for colored waste bottle glass. Silica was hydrothermally extracted and the mesoporous silica including alkali-earth metal elements was synthesized which have great ion exchangeability for rare earth metal cations.
Prediction of bone formation rate of bioceramics using machine learning and image analysis
To practically utilize artificial bones, scanning electron microscope (SEM) images of artificial bones are used to analyze their properties and extract important features for predicting bone formation rate, including grain size and contour.
Modification of silicon-polyurethane-based sol–gel coatings through diverse plasma technologies: investigation of impact on surface properties
In this study, the chemical and physical properties of sol–gel coatings were analyzed after curing with various atmospheric plasma sources.
Selective fluorination of the interlayer surface of layered silicates
Neutral fluoride substances were intercalated into layered silicates, facilitating the selective fluorination of inner surfaces.
Exfoliation and restacking route to Keggin-Al13-treated layered ruthenium oxide for enhanced lithium ion storage performance
Ruthenium oxide nanosheets were used as hosts for the Keggin-Al13. The synthesized AR-150 has stable cycling performance as an anode material for lithium-ion batteries.
About this collection
Functional materials such as energy and environmental materials, biomaterials, as well as gypsum, lime and cement materials, are experiencing remarkable growth in research interest.
The International Symposium on Inorganic Environmental Materials 2023 (ISIEM 2023, https://isiem2023.sciencesconf.org), was the 4th symposium after Eindhoven (Netherlands, 2004), Rennes (France, 2013) and Ghent (Belgium). To-date, the symposium has supported the growth of this research field by providing an international forum for the discussion of cutting-edge results.
We hope that ISIEM 2023 has helped to broaden knowledge and generate new interdisciplinary proposals through active discussions among the participants. To celebrate the success of ISIEM 2023 and as a source of further information exchange, we have put together this collection of research by presenters at ISIEM 2023.
