Palaeobathymetry of the Abderaz Formation using foraminifera, Iran [PDF]

open access: yes, 2009
Abderaz Formation at its type section with an age of Turonian-early Campanian and a thickness of 300 m contains light grey shale and marl. The study of the planktonic foraminifera in isolated form led to differentiate three morphotype groups.

Rational Fine‐Tuning of MOF Pore Metrics: Enhanced SO2 Capture and Sensing with Optimal Multi‐Site Interactions

open access: yesAdvanced Functional Materials, EarlyView.
A pore tuning strategy to amplify the multi‐site MOF‐SO2 interactions is proposed to achieve an enhanced trace SO2 capture and chemiresistive sensing in highly stable isostructural DMOFs by annelating benzene rings. This work provides a facile strategy to achieve tailor‐made stable MOF materials for specific multifunctional applications.

A third locality for the milliped Mitocybe auriportae Cook and Loomis, 1928 (Platydesmida: Andrognathidae) [PDF]

open access: yes, 2012
With the discovery of Mitocybe auriportae Cook and Loomis, 1928 (Platydesmida: Andrognathidae) in Alameda County (Co.), east of San Francisco Bay, a potential overall distribution in coastal California is projected based on those of partly congruent ...

Enhancing CoFe Catalysts with V2CTX MXene‐Derived Materials for Anion Exchange Membrane Electrolyzers

open access: yesAdvanced Functional Materials, EarlyView.
MXene dervied CoFe composites show increased initial Oxygen Evolution Reaction (OER) activity compared to the pure CoFe and MXene in an Anion Exchange Membrane device. Vanadium vacancies in the MXene plays a role in increased OER activity and hinders Fe leaching in the AEM device over using the pure V2C MXene as a support material for the CoFe ...

Ornamentalism

open access: yes, 2011
"A pleasurable and illuminating collection that sets out the important implications of accessories and shows how conspicuous consumption and ornamental ostentation aim to secure status and display affiliation. "Ornamentalism" explains how accessories carry heavily laden symbolic and mnemonic significance, given their age, beauty, and value."---Richard ...

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 ...

How one Learned to Ornament in Late Sixteenth-Century Italy [PDF]

open access: yes, 2012
Several of the sixteenth-century ornamentation manuals state that they are self-sufficient tutors; that instrumentalists and vocalists could learn the skill without further assistance from a teacher.

Light‐Controlled Reversible Coassembly of Hybrid Functional Nanostructures

open access: yesAdvanced Functional Materials, EarlyView.
Light‐responsive hybrid nanostructures are formed by coassembling azobenzene‐ and PAH‐functionalized nanoparticles through reversible an tunable π interactions. The system enables tunable coupling between distinct components such as gold and magnetite or carbon nanotubes, producing switchable optical and magnetic properties under light and magnetic ...
