Introduction of Mercury-free Gold Extraction Methods to Medium-Scale Miners and Education of Health Care Providers to Reduce the use of Mercury in Sorata, Bolivia

open access: yesJournal of Health and Pollution, 2015
Background. Artisanal and small-scale miners in Bolivia release on the order of 120 tons of mercury annually. The mercury finds its way to the Amazon with catastrophic consequences for the biosphere. A project aimed at reducing the release of mercury was

3D‐Printed Multidimensional Bionic Mg‐MC/PLGA Composite for Tailored Repair of Segmental Long Bone Defects

open access: yesAdvanced Healthcare Materials, EarlyView.
This study develops 3D‐printed Mg‐MC/PLGA scaffolds with varying Mg concentrations (0–20%). The 5% Mg scaffold shows optimal cytocompatibility, osteogenic activity in vitro, and significantly enhances bone regeneration in rabbits, improving bone volume and mechanical strength.

Engineering Volumetric Tissue Analogs via Assembly of Endothelial Cell‐Covered Spheroidal Microtissues

open access: yesAdvanced Healthcare Materials, EarlyView.
An engineering strategy to fabricate highly vascularized volumetric tissues with capillary networks is developed. Endothelial cell‐covered spheroidal microtissues with high structural integrity are efficiently produced using bioprinting technology. These spheroidal microtissues are then assembled and cultured under perfusion conditions, resulting in ...

Advancements in Understanding the Physicochemical Properties of Reticular Materials: An In Situ and Operando Spectroscopic Perspective

open access: yesAdvanced Materials, EarlyView.
This review explores how in situ and operando spectroscopic techniques reveal the real‐time behavior of reticular materials, including MOFs and COFs. These methods track material formation and functionalization, structural changes, defect formation, dynamic responses to external triggers, and catalytic processes.

State‐of‐the‐Art, Insights, and Perspectives for MOFs‐Nanocomposites and MOF‐Derived (Nano)Materials

open access: yesAdvanced Materials, EarlyView.
Different approaches to MOF‐NP composite formation, such as ship‐in‐a‐bottle, bottle‐around‐the‐ship and in situ one‐step synthesis, are used. Owing to synergistic effects, the advantageous features of the components of the composites are beneficially combined, and their individual drawbacks are mitigated.
