Metal‐Free Ternary‐Composite Aerogel Based on Graphitic Carbon Nitride, Graphene Oxide, and β‐Cyclodextrin for Synergistic Adsorption and Photodegradation of Organic Dyes

open access: yesSmall, EarlyView.
A novel metal‐free g‐C3N4/GO/β‐CD aerogel exhibits a high adsorption capacity of 653.2 mg/g for RhB. The synergistic adsorption‐degradation effect of the aerogel enables the complete elimination of organic dyes. Fixed‐bed and recyclability tests demonstrate its potential for continuous industrial wastewater treatment.

Synthesis, modification, and chlorhexidine loading of polymer modified‐HM‐HAP particles: In vivo antibacterial analysis and cell cytotoxicity assessment

open access: yesSmart Molecules, EarlyView.
This study presents the synthesis of hollow mesoporous hydroxyapatite (HM‐HAP) particles modified with different weights PEG and PEI. Chlorhexidine was loaded onto the particles. SEM analysis confirmed no significant morphological changes. Antibacterial activity was tested in vitro and in vivo using mouse oral bacteria, demonstrating promising results.

The Material Basis of 18th‐Century Meissen Porcelain

open access: yesArchaeometry, EarlyView.
ABSTRACT In the summer of 1708, the quest for making hard‐paste porcelain from Saxonian clay and other mineral resources succeeded. This was achieved by applying as its essential ingredient newly discovered pure kaolin from Heidelsberg near Aue, western Saxon Ore Mountains.

Application of Multi‐Method Dating for Understanding the Gravettian North of Moravia, Central Europe

open access: yesArchaeometry, EarlyView.
ABSTRACT This article presents the results of integrating three methods to assess the age of the Upper Palaeolithic site of Pietraszyn 11 (SW Poland), close to the Moravian Gate. Sediment chronology determined using optically stimulated luminescence produced promising, yet ambiguous results (51.0 ± 3.7 to 20.3 ± 0.7 ka).

Effects of Surface Abrasion With Airborne‐Particles and Surface Etching With Hydrofluoric Acid on Color Difference and Translucency of Nano‐Hybrid Ceramic

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives To evaluate the effects of alumina airborne‐particle abrasion, glass‐bead airborne‐particle abrasion, and hydrofluoric acid etching of intaglio surfaces on the color difference and translucency of a nano‐hybrid ceramic after cementation to resin abutment specimens, and to analyze the relationships between surface roughness and these
