Natural Aging of Biomaterials in Ambient and Physiological Environments

Advanced NanoBiomed Research, Volume 6, Issue 9, September 2026.
Biomaterials used in biomedical applications can change their physical properties over time, even under ambient and physiological conditions. This review highlights key studies on the natural aging of materials ranging from soft hydrogels to metals and ceramics, emphasizing how time‐dependent changes influence function and performance.

Endodontic and Surgical Management of External Cervical Root Resorption: A Case Report

Clinical Case Reports, Volume 14, Issue 9, September 2026.
ABSTRACT This study describes the treatment of tooth #9 exhibiting external cervical root resorption (ECR) and apical root resorption. A therapeutic approach—including root canal therapy with MTA apexification, surgical debridement of resorptive tissue at the ECR site, and sealing of the defect—was necessary to eliminate the infection.

Internal Root Resorption in a Previously Endodontically Treated Maxillary Molar: Nonsurgical Retreatment With Cold Ceramic

Clinical Case Reports, Volume 14, Issue 9, September 2026.
ABSTRACT Internal root resorption in a previously endodontically treated maxillary molar is an exceptionally rare finding. This case demonstrates that CBCT is essential for accurate lesion characterization, and obturation with Cold Ceramic yielded a favorable short‐term radiographic stabilization at 15‐month follow‐up in the nonsurgical retreatment of ...

Flexural bulges and foredeep basins: Dynamic tectonic control on shifting depocentres and condensed facies, Upper Cretaceous (Santonian), Western Canada Foreland Basin

The Depositional Record, Volume 12, Issue 4, September 2026.
Allostratigraphically defined mudstone packages show marked along‐strike thickness variation, interpreted to be related to shifting thrust activity in the orogen; loading cycles lasted about 750 kyr. Close to the orogen, the forebulge is mantled by shelly sandstone whereas far from the orogen, the forebulge is typified by organic‐rich mudstone ...

High‐Value Utilization of Typical Vanadium‐Bearing Solid Wastes: Mineralogy, Pathways, and Perspectives

Rare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Vanadium‐bearing solid wastes (VBSWs) have emerged as a key research priority in resource recovery and environmental remediation because of their high resource value, large generation volume, and complex phase composition. However, practical utilization of these wastes still faces major challenges, including heavy environmental burdens, ill ...

Formation and Alteration of Magnesite Nodules From Kunwarara, Queensland, Australia, as an Analog to Mg‐Carbonate Formation on Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.
Abstract Magnesite (MgCO3) is a magnesium (Mg) carbonate mineral that records the aqueous environmental conditions of its formation. On Earth, magnesite forms in metamorphic, diagenetic or pedogenic environments, and distinguishing between these environments is critical for understanding the fluid chemistry during magnesite precipitation. Mg carbonates

Effects of silica addition on the chemical, mechanical and biological properties of a new α-Tricalcium Phosphate/Tricalcium Silicate Cement

Materials Research, 2011
The addition of tricalcium silicate (C3S) to apatite cements results in an increase of bioactivity and improvement in the mechanical properties. However, adding large amounts raises the local pH at early stages, which retards the precipitation of ...

Substitutions of strontium in bioactive calcium silicate bone cements stimulate osteogenic differentiation in human mesenchymal stem cells

, 2019
[[abstract]]Calcium silicate cements have been considered as alternative bone substitutes owing to its extraordinary bioactivity and osteogenicity. Unfortunately, the major disadvantage of the cements was the slow degradation rate which may limit the ...
