Transformational learning experiences on productive-failure approach in Mamthematics

open access: yesDiversitas Journal
A learning failure is not always a denial of knowledge but an opportunity to be productive in the academic pursuit in the field of mathematics. This qualitative case study explored the students’ experiences with the utilization of the Productive-Failure

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.

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.

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

open access: yesAdvanced 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.

Tunable Thermoshrinkable Hydrogels for 4D Fabrication of Cell‐Seeded Channels

open access: yesAdvanced Functional Materials, EarlyView.
A thermoresponsive polymer with methacrylate groups for photo‐cross‐linking, based on polyethylene glycol, N‐isopropylacrylamide, and 2‐hydroxyethyl acrylate is synthetized to yield hydrogels that shrink upon temperature increase. The new polymer enables the fabrication of cell‐laden perfusable channels with diameters below 200 µm by combining ...

Mathematical Foundations of Field Theory

open access: yes, 2015
A mathematically rigorous Hamiltonian formulation for classical and quantum field theories is given. New results include clarifications of the structure of linear fields, and a plausible formulation for nonlinear fields. Many mathematical formulations of field theory suffer greatly from either a failure to explicitly define the field configuration ...
