Effects of autoclave sterilization on the dimensional stability of implant surgical guides: A 3D in vitro analysis

Journal of Prosthodontics, EarlyView.
Abstract Purpose Surgical guides are medical devices used in static implant surgery to replicate the prosthetic and surgical implant position planned with computer‐assisted software before surgery. Their use reduces invasiveness and improves safety and outcomes of implant surgery, provided that their accuracy is ensured from design to manufacturing and

Polymict melt‐bearing breccia dikes in the Morokweng impact structure formed by slip‐induced mechanical mixing of pseudotachylite and cataclasite along large‐displacement impact faults

Meteoritics &Planetary Science, EarlyView.
Abstract A core drilled through shocked and faulted Archean granitoid gneisses and dolerites in the eroded peak ring of the 70–80 km diameter Morokweng impact structure intersects multiple centimeter‐ to meter‐wide clastic‐matrix breccias containing a polymict clast population of lithic and mineral clasts and altered, millimeter‐ to centimeter ‐size ...

Microplastic Dynamics in Sediment Layers of Two Ramsar‐Designated Wetlands

Water and Environment Journal, EarlyView.
ABSTRACT Little is known about the vertical and spatial dynamics of microplastics in relation to hydrology and land use, particularly in African context. This study aimed to assess the abundance, type, colour and vertical distribution of microplastics in sediment from two Ramsar‐designated wetlands, the Makuleke and Nylsvley. Sediment core samples were

The Occurrence of Microplastic Ingestion in Commercial Marine Fish in Miri, Sarawak, Malaysia

Environmental Quality Management, Volume 35, Issue 4, Summer 2026.
ABSTRACT Microplastics are polymer‐based particle compositions of various toxic chemicals with size less than 5 mm. Due to their small size, microplastics can be ingested and accumulate in body tissues of organisms. This raises concerns about their toxicity being transferred to humans via food consumption.

Rapid Detection of Plasticizer Migration From UV‐Aged PVC Films by DART‐HRMS

Rapid Communications in Mass Spectrometry, Volume 40, Issue 10, 30 May 2026.
ABSTRACT Rationale The migration of phthalate plasticizers from high‐volume polymers, such as poly(vinyl chloride) (PVC), raises significant toxicological concerns, particularly when materials are subjected to aging and environmental stress. As traditional monitoring techniques rely on time‐consuming solvent extraction and chromatographic methods that ...

The design of an Fe-12Mn-O.2Ti alloy steel for low temperature use [PDF]

An investigation was made to improve the low temperature mechanical properties of Fe-8 approximately 12% Mn-O 2Ti alloy steels. A two-phase(alpha + gamma) tempering in combination with cold working or hot working was identified as an effective treatment.
