The Significance of Resorption During Anoxic Mobilization of Phosphorus [PDF]

, 2009
Phosphorus has a fundamental role in the regulation of biotic cycles in both aquatic and terrestrial environments. Phosphorus is in fact the limiting nutrient for plants in the majority of the cases.

Phase‐Pure and Size‐Tunable Tin Halide Perovskite Quantum Dots

Advanced Materials, EarlyView.
A trioctylphosphine oxide modulated protocol allows for the synthesis and study of the optical properties of a broad library of tin halide perovskite quantum dots across multiple A‐ and X‐site compositions with precise size tuning while eliminating unwanted 2D phases.

Electrophilic aryl spiroannulation induced by diaryliodonium salts: efficient synthesis of [5,5]-spiro lactone-lactam scaffolds from α-cyanocarboxylates

Green Synthesis and Catalysis
Spirocyclic architectures represent one of the privileged three-dimensional scaffolds in pharmaceutical chemistry and drug discovery, while the new-skeletal synthesis of spiromolecules from simple starting materials remains a challenging task.

Reversible Hydration Tuning of Polar Order and Large Nonlinear Optical Response in a 2D van der Waals Crystal, LiInP2S6

Advanced Materials, EarlyView.
Hydration‐induced symmetry breaking transforms layered LiInP2S6${\rm LiInP}_2{\rm S}_6$ from a nonpolar to a chiral‐polar phase, producing a giant enhancement of non‐resonant second‐harmonic generation. The reversible tuning of polar order through molecular intercalation establishes a strategy for dynamically controlling nonlinear optical ...

Escaping the Scaling Relationships in Oxygen Reduction Catalysis: Implications for PEM Fuel Cells

Advanced Materials, EarlyView.
Escaping the scaling relationships of the oxygen reduction reaction is vital for hydrogen fuel cells. This outlook examines how interfacial heterogeneity, spanning the subsurface lattice, chemisorption layer, and near‐interface solvation volume, mechanistically decouples intermediate binding energetics.

Selective radical-type perfluoro-tert-butylation of unsaturated compounds with a stable and scalable reagent

Nature Communications
Despite the promising potential of the perfluoro-tert-butyl group in diverse fields such as magnetic resonance imaging, material science and drug design, incorporating this group into organic molecules is still a formidable task, primarily due to its ...

Zirconoarylation of alkynes through p-chloranil-promoted reductive elimination of arylzirconates

Beilstein Journal of Organic Chemistry, 2014
A novel method for the zirconoarylation of alkynes was developed. TCQ-promoted reductive elimination of arylzirconate [LiCp2ZrAr(RC≡CR)], which was prepared by the reaction of zirconocene–alkyne complexes with aryllithium compounds, afforded ...
