Petrology of the Eocene alkaline volcanism from the western Rio Grande Rise, South Atlantic Ocean

open access: yesFrontiers in Earth Science
The origin and evolution of the Rio Grande Rise is deeply related to the opening of the South Atlantic Ocean. The geology of the plateau records the transition from divergent plate margins at the Mid-Atlantic Ridge to an intraplate tectonic setting ...

Graded Hydroxyapatite Triply Periodic Minimal Surface Structures for Bone Tissue Engineering Applications

open access: yesAdvanced Healthcare Materials, EarlyView.
This study investigates the role of triply periodic minimal structures in load bearing bone tissue engineering applications. Research uses a combination of mechanical testing, material characterization, and in vitro tests to study the impact of TPMS lattice structures (gyroid, lidinoid and split‐P).

Longer Acting Injectable: Continuous, Linear Release of a Progestin Contraceptive From an Oxidized Porous Silicon Host

open access: yesAdvanced Healthcare Materials, EarlyView.
Progestin drugs are loaded into a mesoporous silicon dioxide host by melt‐infiltration. Drugs that decompose at or close to their melting point can be loaded by the addition of cholesterol, which acts as a melting point suppressor. High mass loading of the drug is achieved, and dissolution of the composite is controlled by the nanoscale properties of ...

Biogeochemical sulfide mineralization in the volcanic-hosted Tongguan hydrothermal field, southern Mid-Atlantic Ridge

open access: yesFrontiers in Marine Science
Biogeochemical mineralization is increasingly recognized as a significant factor in the formation of submarine hydrothermal sulfide deposits. While several mechanisms by which hydrothermal organisms may facilitate metal deposition have been documented in

Cold Atmospheric Plasma Selectively Disrupts Breast Cancer Growth in a Bioprinted 3D Tumor‐Stroma Co‐Culture Model

open access: yesAdvanced Healthcare Materials, EarlyView.
This research introduces a cold plasma‐based platform for treating breast cancer bone metastases. Using a novel bioprinted 3D tumor‐stroma model, it highlights the selective antitumor effects of plasma‐generated reactive species. The platform aims to advance non‐invasive therapeutic strategies, offering potential clinical applications in controlling ...

Advanced Oral Delivery Systems for Nutraceuticals

open access: yesAdvanced Healthcare Materials, EarlyView.
Emerging delivery technologies are explored to overcome barriers to oral nutraceutical absorption. Traditional carriers are compared with novel platforms including biodegradable polymers, MOFs, MPNs, and 3D printing. These systems enhance bioavailability, control release, and enable personalized nutrition.
