Characterization of coesite‐bearing impact melt glass from the Hapcheon crater, Korea: Trimodal phase architecture, shock metamorphism, and implications for 40Ar/39Ar geochronology

Meteoritics &Planetary Science, EarlyView.
Abstract We present the first micrometer‐scale, phase‐resolved compositional characterization of impact melt glass from the Hapcheon crater (~1.4 km apparent diameter), the first confirmed impact structure on the Korean Peninsula, integrating EPMA‐WDS (5 μm spot), confocal Raman spectroscopy (<1 μm spot), XRD, and 40Ar/39Ar step‐heating geochronology ...

Long‐term stability of conventional non‐regenerative periodontal treatment for furcation defects

Periodontology 2000, EarlyView.
Abstract Background Furcation involvement (FI) in multi‐rooted teeth poses significant challenges in periodontal therapy due to complex anatomy and difficulty in achieving effective maintenance. FI is associated with increased periodontal destruction, especially in sites with narrow furcation entrances and deep root concavities.

Exploring a new Portland cement-free calcium silicate cement —Part 1: Synthesis of dicalcium and tricalcium silicate

Dental Materials Journal
Mineral trioxide aggregate cement is an excellent pulp-capping material; however, its base Portland cement contains highly toxic elements and is expensive. This study aimed to explore the possibility of using calcium silicate cement without Portland cement.

The effects of bioturbation on porewater chemistry and early marine diagenesis: Evidence from a modern intertidal zone in Abu Dhabi, U.A.E.

Sedimentology, EarlyView.
ABSTRACT Early marine carbonate cements generally form in CaCO3‐supersaturated seawater at the seabed or shallow burial depths, resulting in syn‐sedimentary cemented firmgrounds and hardgrounds. The processes controlling early marine diagenesis are complex, particularly in coastal environments where geochemistry is influenced by different water sources

Premixed calcium silicate cement for endodontic applications

, 2011
Calcium silicate-based materials (also called MTA) are increasingly being used in endodontic applications. However, the handling properties of MTA are not optimal when it comes to injectability and cohesion. Premixing the cements using glycerol avoids these issues.

Mineral Carbonation of Mixed Industrial Residues for Enhanced CO2 Sequestration and Environmental Stabilization: The Role of Slag Composition and Industrial Symbiosis

Advanced Energy and Sustainability Research, Volume 7, Issue 9, September 2026.
Accelerated CO2 carbonation transforms mixed industrial by‐products, including bottom ash (BA), fly ash (FA), and steel slags, into a value‐added material. The carbonated residue is used as a filler for HDPE composites, promoting both carbon sequestration and circular resource utilization.
