Mathematics of students’ culture: A goal of localized ethnomathematics

open access: yesRevista Latinoamericana de Etnomatemática, 2015
Ethnomathematics is the mathematics of cultural groups, but often those cultural groups are “others” and “elsewhere”. However, it is also valuable to look inward to see the interaction of mathematics and one’s own culture.

High‐Entropy Liquid Metal Process for Transparent Ultrathin p‐Type Gallium Oxide

open access: yesAdvanced Functional Materials, EarlyView.
This work introduces a doping strategy for harvesting ultrathin Ga oxide layers using a multi‐elemental Ga‐based liquid metal alloy. The incorporation of trivalent In metal into the self‐limiting oxide formed on the alloy's surface is enabled by the existence of atomically dispersed Pt, Au, and Pd.

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

open access: yesAdvanced 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.

Tetrahedral Tilting and Lithium‐Ion Transport in Halide Argyrodites Prepared by Rapid, Microwave‐Assisted Synthesis

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces a rapid, microwave‐assisted synthetic method for halide argyrodite solid‐state electrolytes Li6PS5X${\rm Li}_6 {\rm PS}_5X$ (X=$X =$ Cl−${\rm Cl}^-$, Br−${\rm Br}^-$, I−${\rm I}^-$). Microwave synthesis increases S2−${\rm S}^{2-}$/X−$X^-$ site disorder and rotational disorder of the isolated PS43−${{\mathrm{PS}}_{4}}^{3 ...

NanoMOF‐Based Multilevel Anti‐Counterfeiting by a Combination of Visible and Invisible Photoluminescence and Conductivity

open access: yesAdvanced Functional Materials, EarlyView.
This study presents novel anti‐counterfeiting tags with multilevel security features that utilize additional disguise features. They combine luminescent nanosized Ln‐MOFs with conductive polymers to multifunctional mixed‐matrix membranes and powder composites. The materials exhibit visible/NIR emission and matrix‐based conductivity even as black bodies.
