Is It Real Type‐II or S‐Scheme? A Three‐Phase Diagnostic Protocol for Identifying Potentially Mislabeled Heterojunction Photocatalysts

open access: yesAdvanced Functional Materials, EarlyView.
Diagnostic analysis via the heterojunction validation funnel. The funnel illustrates the hierarchical stratification of 30 reported Type‐II systems based on the three‐phase, seven‐step diagnostic framework. Complete validation through all phases is achieved by only 3.3% of systems, while 96.7% lack full mechanistic validation, revealing a pervasive ...

Coagulative Granular Hydrogels with an Enzyme Catalyzed Fibrin Network for Endogenous Tissue Regeneration

open access: yesAdvanced Healthcare Materials, EarlyView.
Coagulative granular hydrogels are composed of packed thrombin‐functionalized microgels that catalyze the conversion of fibrinogen into a secondary fibrin network, filling the interstitial voids. This bio‐inspired approach stabilizes the biomaterial to match the robustness of bulk hydrogels without compromising injectability, mimicking the initial ...

Vanadium(V) extraction from hydrochloric acid solutions by neutral oxygen-containing extracting agents

open access: yesТонкие химические технологии, 2013
The paper considers vanadium (V) distribution during its extraction from hydrochloric acid solutions by phosphorus-containing extracting agents. It has been shown that vanadium can be concentrated in one of the phases during the extraction processing of ...

Aqueous Two‐Phase Bioinks for Discrete Packing and Compartmentalization of 3D Bioprinted Cells

open access: yesAdvanced Healthcare Materials, EarlyView.
Aqueous two‐phase systems (ATPS) enable the formation of biomimetic interfaces crucial for tissue engineering. However, clinical translation remains limited by the challenge of precisely controlling cellular compartmentalization. Here, we developed ATPS biomaterial inks for 3D bioprinting allowing tuneable droplet formation via NaCl modulation.

Thermal decomposition of zinc hexacyanometalates in various gas media

open access: yesChemical Thermodynamics and Thermal Analysis
Prussian blue analogues with formulae Zn3[Co(CN)6]2·10H2O and Zn3[Fe(CN)6]2·4H2O have been synthesized. Their thermal decomposition was studied in oxidizing (air), reducing (hydrogen) and inert (argon) atmospheres in the temperature range from 20 to 1000°

Essential elements and heavy metal concentrations in a small area of the Castlecomer Plateau, Co. Kilkenny, Ireland: Implications for animal performance.

open access: yes, 2011
peer-reviewedMany ruminants are solely or mostly dependant for their nutrients, including essential elements, on the forage available to them, either in its natural state or conserved as hay or silage. A soil and herbage survey was carried out in April
