Impact of nitrogenous fertilizers on carbonate dissolution in small agricultural catchments: Implications for weathering CO2 uptake at regional and global scales [PDF]

open access: yes, 2008
The goal of this study was to highlight the occurrence of an additional proton-promoted weathering pathway of carbonate rocks in agricultural areas where N-fertilizers are extensively spread, and to estimate its consequences on riverine alkalinity and ...

Mesoporous Bioactive Glasses: A Powerful Tool in Tissue Engineering and Drug Delivery

open access: yesAdvanced Healthcare Materials, EarlyView.
This work is a comprehensive revision of bioactive glasses (BGs), pioneered by Prof. L.L. Hench, which are key in bone repair and regenerative medicine. Sol–gel methods and mesoporous designs enhanced their bioactivity, ions, and drug delivery. BGs now support gene therapy and 3D‐printed scaffolds, enabling personalized, multifunctional treatments in ...

Granular Hydrogels as Modular Biomaterials: From Structural Design to Biological Responses

open access: yesAdvanced Healthcare Materials, EarlyView.
Granular hydrogels are now emerging as promising biomaterials due to their inherent microporousity, injectability, and modularity. They have shown improvements in cell viability and migration, cellular/tissue infiltration, host tissue integration, mitigated foreign body response, and tissue regeneration.

Carbonate-silicate ratio for soil correction and influence on nutrition, biomass production and quality of palisade grass

open access: yesScientia Agricola, 2011
Silicates can be used as soil correctives, with the advantage of being a source of silicon, a beneficial element to the grasses. However, high concentrations of silicon in the plant would affect the digestibility of the forage.

Theoretical Spectra of Terrestrial Exoplanet Surfaces [PDF]

open access: yes, 2012
We investigate spectra of airless rocky exoplanets with a theoretical framework that self-consistently treats reflection and thermal emission. We find that a silicate surface on an exoplanet is spectroscopically detectable via prominent Si-O features in ...

Borate‐Ion‐Stimulated Macrophages Promote Osteogenic Differentiation of Mesenchymal Stem Cells

open access: yesAdvanced Healthcare Materials, EarlyView.
The immune responses of mouse macrophages stimulated by borate ions promote the osteogenic differentiation and mineralization of mouse bone marrow–derived mesenchymal stem cells in an ion‐dose‐dependent manner by providing cytokines, including BMP‐2.
