Nanoparticulate hydroxyapatite and calcium-based CO2 sorbents [PDF]

, 2012
This thesis is focused on the development of synthesis and characterisation protocols for two different nanoparticulate materials; hydroxyapatite (HA), a biomaterial well recognised as chemically akin to human bone, and CaO, a material often used for the

Diffuse flow environments within basalt- and sediment-based hydrothermal vent ecosystems harbor specialized microbial communities [PDF]

, 2013
Hydrothermal vents differ both in surface input and subsurface geochemistry. The effects of these differences on their microbial communities are not clear.

Oxygen Evolution Electrocatalysts with Trinuclear, Mixed‐Valence Iron Motifs on Electronically Aligned Carbon Dots

Advanced Functional Materials, EarlyView.
Trinuclear iron oxo‐bridged catalytic ensembles stabilized by aspartic‐acid‐derived carbon dots provide an effective platform for alkaline oxygen evolution. Mixed‐valence charge balancing, inner‐sphere charge transport, and work‐function alignment within the N/O‐rich carbon framework promote cooperative Fe‐site chemistry and efficient OER ...

Emergence of a Hexagonal Fe2S2 Single Layer Without a Bulk Counterpart via Phase Transformation

Advanced Functional Materials, EarlyView.
Upon annealing, single‐layer Mackinawite iron sulfide transforms into a previously unknown hexagonal Fe2S2${\rm Fe}_2{\rm S}_2$ phase with β$\beta$‐CuI structure. STM, LEED, and first‐principles calculations identify the structure and show that electronic correlations and magnetic order are important for its stability.

Hydrothermal conversion of analcime-pollucite solid solution from soil for immobilization of Cs in situand its characterization

Materials Research Express, 2021
Pollucite, considered as an ideal host material for immobilization of Cs, rarely exists in pure form but analcime-pollucite solid solution in nature due to the coexistence of Cs and Na in fact.

The hydrothermal synthesis of nanomaterials

Rad Hrvatske akademije znanosti i umjetnosti. Tehničke znanosti
Nanomaterials can be prepared by means of various synthesis methods, such as sol-gel synthesis, combustion synthesis, mechanochemical synthesis, etc. Among numerous nanosynthesis methods, hydrothermal synthesis is one of the most commonly used. Hydrothermal/solvothermal reaction is defined as a chemical reaction that occurs in a closed reaction vessel ...
