Designing of Self‐Dispersing Soft Dendritic Microcleaners for Microplastics Capture and Recovery

Advanced Functional Materials, EarlyView.
The capture and recovery of microplastics from open aquatic systems is a complex problem, which necessitates nontrivial solutions. The principles of a comprehensive multistage process based on sustainably sourced microcleaners with hierarchical morphology are demonstrated.

Chasing Charge Carriers: Diffusion Dynamics in Mixed‐n Quasi‐2D Colloidal MAPbBr3 Perovskites

Advanced Functional Materials, EarlyView.
Metal halide perovskites are noted for their tunable optical properties. Colloidal synthesis allows the formation of differently shaped perovskite nanocrystals with varying optical and carrier transport behavior. Three MAPbBr3 morphologies are characterized: nanoplatelets, nanosheets, and nanostripes.

On a Division Algebra Classification of Constrained Generalized Supersymmetries [PDF]

PoS WC2004 (2004) 047, 2005
In this talk we present a division-algebra classification of the generalized supersymmetries admitting bosonic tensorial central charges. We show that for complex and quaternionic supersymmetries a whole class of compatible division-algebra constraints can be imposed. Possible applications to M-theory related dynamical systems are briefly mentioned.

Low‐Loss Far‐Infrared Surface Phonon Polaritons in Suspended SrTiO3 Nanomembranes

Advanced Functional Materials, EarlyView.
The low‐loss, highly confined, and thickness‐tunable surface phonon polaritons are demonstrated in the far‐infrared regime within transferable freestanding SrTiO3 membranes, achieving high figures of merit comparable to the previous record values from the vdW materials.

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

Advanced 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 ...

Divisibility Properties of Coefficients of Level $p$ Modular Functions for Genus Zero Primes [PDF]

Proceedings of the American Mathematical Society 141 (2013), 41-53, 2011
Lehner's 1949 results on the $j$-invariant showed high divisibility of the function's coefficients by the primes $p\in\{2,3,5,7\}$. Expanding his results, we examine a canonical basis for the space of level $p$ modular functions holomorphic at the cusp 0.
