Geophysical Monograph Series, Page 1-26., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Determination of Surface Characteristics, Solubility and Ion Release of a Calcium Silicate Root Canal Sealer. [PDF]
Aust Endod JABSTRACT This study investigated the solubility of AH Plus Bioceramic sealer (AHPB), the ion release, and the modification of surface characteristics compared to AH Plus (AHP). Solubility was examined according to ISO guidelines in deionised water and phosphate buffer saline (PBS) for 3 months.

Advanced Energy and Sustainability Research, EarlyView.A novel polylactic acid/wax electret composite is developed, combining biodegradability with long‐term charge stability. The study investigates charge storage behavior, structural morphology, and thermal performance. Results reveal a notable charge retention recovery after thermal stress and exhibit stable surface potential over 2 kV. This eco‐friendly

The Anatomical Record, EarlyView.Abstract Silesaurids (Archosauria: Dinosauriformes) are found in Middle to Upper Triassic deposits across Pangea, but few stratigraphic sections record the evolution of the group in one geographic area over millions of years. Here, we describe silesaurid remains from the oldest of the Upper Triassic stratigraphic sequence from the base of the Dockum ...

The Depositional Record, EarlyView.Microbialites are common throughout the rock record and key to our understanding of Earth history, yet a relatively common microscopy technique—cathodoluminescence (CL)—has not previously been leveraged to understand them. In this contribution, we examine microbialites of varying ages (modern to Proterozoic) with CL and report on the patterns and ...
