Broiler physiological response to low phosphorus diets at different stages of production

open access: yesPoultry Science, 2023
: Phosphorus (P) inclusion in broiler diets needs to meet the physiological demands at a specific developmental stage to ensure the performance, health, and welfare of the birds and minimize nutrient losses.

Search for New Superconductors: An Electro-Magnetic Phase Transition in an Iron Meteorite Inclusion at 117 K [PDF]

open access: yesarXiv, 2015
The discovery of superconductivity in pnictides and iron chalcogenides inspires the search for new iron based superconducting phases. Iron-rich meteorites present a unique opportunity for this search, because they contain a broad range of compounds produced under extreme growth conditions.

Characteristics and carbon stable isotopes of fluids in the Southern Kerala granulites and their bearing on the source of CO2 [PDF]

open access: yes
Carbon dioxide-rich inclusions commonly occur in the banded charnockites and khondalites of southern Kerala as well as in the incipient charnockites formed by desiccation of gneisses along oriented zones.

Magnetically Guided Mechanoactive Mineralization Scaffolds for Enhanced Bone Regeneration

open access: yesAdvanced Functional Materials, EarlyView.
A 3D‐printed ‘rebar‐concrete’ inspired scaffold (PGS‐P@MGel) synergizes spontaneous biomineralization with magneto‐mechanical stimulation through PDA@Fe3O4‐embedded hydrogel. This dual biointerface activates Piezo1/β‐catenin/YAP mechanotransduction axis, enhancing BMSCs osteogenesis and angiogenesis simultaneously.

A Hibonite-Pyroxene Spherule in Allan Hills 77307 (CO3.03): Petrography and Mineralogy [PDF]

open access: yesarXiv, 2017
Hibonite-pyroxene spherules are an extremely rare kind of refractory inclusion that show a wide range of exotic isotopic properties despite their defining similarity and simplicity in morphology and mineralogy. One such, relatively large (about 120 micron diameter), inclusion has been found in one of the most pristine meteorites, Allan Hills 77307 (a ...

Isotopic and Microstructural Analyses of Opaque Mineral Assemblages and Their Alteration Products Hosted in a Refractory Inclusion [PDF]

open access: yes
Calcium-aluminum-rich inclusions (CAIs) hosted in primitive meteorites are the oldest solids formed in the Solar System. Some CAIs contain metal nuggets that are complex assemblages of Fe-Ni alloys, along with rare ultra-refractory metals such as ...

Discovery of Panguite, a New Ultra-Refractory Titania Mineral in Allende [PDF]

open access: yes, 2011
During our nano-mineralogy investigation of the Allende meteorite, we identified a new titania mineral named “panguite” in an ultra-refractory inclusion within an amoeboid olivine aggregate (AOA). It has an orthorhombic Pbca structure related to the

Inclusive Reaction by Swellable Clay Minerals. III

open access: yesJournal of Japan Oil Chemists' Society, 1991
The solubilization behavior of a poorly water-soluble drug (griseofulvin : GF) was examined using swellable clay minerals. The solubility of GF in pure water markedly increased by complex formation with clay minerals. GF in the complex was completely solubilized in pure water for the samples at a GF/clay mineral ratio less than 10 wt %.

Self‐supportive Three‐Way Photoelectrochemical System Achieving Uranium Recycling, Organic Oxidation, and Electricity Generation in Complex Waters

open access: yesAdvanced Functional Materials, EarlyView.
A self‐sustaining solar photoelectrochemical cell (SS‐PEC) is developed to recover uranium from aqueous UO22+ with concurrent organic oxidation and electricity production. The monolithical photoanode directly captures electrons from organic compounds, leading to the oxidation of organic compounds and the decomposition of uranium‐organic complexes ...

Mineral host inclusion systems are a window into the solid-state rheology of the Earth

open access: yesCommunications Earth & Environment
Natural processes such as earthquakes, volcanism and orogenesis are controlled by plate tectonics which, in turn, depend on how rocks and minerals, the building blocks of Solid Earth, deform under different environmental conditions.
