A Comparative Investigation of Undergraduate Dental Student Stress in the Management of Deep and Moderate Carious Lesions

open access: yesInternational Endodontic Journal, Volume 59, Issue 6, Page 1200-1212, June 2026.
ABSTRACT Aim The primary objective of this clinical study was to analyse, through physiological and psychological parameters, undergraduate dental student stress during the management of deep compared with moderate carious lesions. Additional objectives aimed to compare student confidence, anxiety and satisfaction during deep and moderate caries ...

Phlogopite Mica Under Acidic and Alkaline Conditions: Reactivity and Silicate Gel Formation

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 6, June 2026.
ABSTRACT Alkali‐activated materials (AAMs) produced using industrial residues offer a sustainable alternative to Portland cement, the production of which contributes nearly 8% of global CO2 emissions. However, commercial sodium silicate, commonly used as an activator, remains costly and energy‐intensive to produce, motivating the development of ...

Development of Holocene lacustrine microbialites on the Iberian Peninsula: Insights into environmental and depositional controls using X‐ray CT and petrography

open access: yesSedimentology, Volume 73, Issue 4, Page 1148-1184, June 2026.
ABSTRACT Microbial mats and microbialites are common in modern and ancient saline lacustrine environments and are highly responsive to biological and environmental factors. As such, they represent important sources of high‐resolution environmental data across a wide range of geological time. Nonetheless, interpretation of fossil mats is non‐trivial due

Influence of Sample Preparation and Processing Procedures on the Thermal Diffusivity of MgO‐C Refractories

open access: yesAdvanced Engineering Materials, Volume 28, Issue 10, 20 May 2026.
The thermal diffusivity of MgO‐C refractories is highly sensitive to sample preparation and processing procedures. In this article, the effects of coking sequence, machining conditions, structural inhomogeneity, and graphite coating application on measurements using laser flash apparatus are systematically investigated.
