Exploring the Landscape of MgO Polymorphs: Stability and the Electronic Band Gap of Promising Candidates

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
In this study, we have investigated possible predicted polymorphs of magnesium oxide (MgO) with respect to their thermodynamic and kinetic stability, as well as their electronic properties, focusing on the possibility of tuning the band gap of the material.

Changes in the Location of the Second Mesiobuccal Canal Orifice After Canal Preparation in Maxillary First Molars

Australian Endodontic Journal, EarlyView.
ABSTRACT This study evaluated angular and linear positional changes of the second mesiobuccal (MB2) canal orifice in maxillary first molars and proposed a guideline for its localization. Twenty‐eight extracted maxillary first molars with four canals were analysed. After access cavity preparation, all canals except MB2 were instrumented. The initial and

Response of Remote Tropical West Pacific Islands to Climate Variability: A Multiproxy Record From T‐Lake, Palau, Spanning the Early Holocene to Present

Archaeometry, EarlyView.
ABSTRACT Lake sediments are natural archives of past environmental dynamics and how these systems have responded to past climate variability. Sediment geochemistry, governed by local geology and climate processes, is unique to each lake‐catchment and geochemical proxies must be validated for each study site.

Gold and Nickel Release From Gold‐Plated Earrings Under Cysteine‐Modified Artificial Sweat Conditions

Contact Dermatitis, EarlyView.
Gold release from gold‐plated earrings was investigated using a cysteine‐modified artificial sweat solution designed to reflect biochemically relevant conditions. This model enabled detection of low‐level gold release. Nickel release was quantified in parallel and was detected in all samples, frequently exceeding established regulatory limits. ABSTRACT

Patch Test Reactions to Dental Materials: A Retrospective Single‐Centre Study

Contact Dermatitis, EarlyView.
In this retrospective single‐centre study of 439 adults referred for suspected delayed‐type hypersensitivity to dental materials, 50.1% had at least one positive patch test reaction, most often to metals. Nickel (23.0%) and palladium (16.6%) pre‐dominated, whilst methacrylate positivity was uncommon (6.2%) and not fully captured by HEMA alone.
