3D‐Printed Nanocarbon Polymer Conductive Structures for Electromagnetic Interference Shielding

open access: yesSmall Methods, EarlyView.
This study introduces EMI shielding bricks by 3D printing PLA composites with carbon‐based fillers such as carbon black and carbon nanotubes, followed by polyaniline coating. It examines how 0D and 1D carbon fillers influence electromagnetic interference shielding efficiency and how this can be further improved by electrodepositing with conductive ...

Self‐Disassembling Macroporous Metal–Organic Framework‐Based Micromotors with Magnetically Controlled Motion for Sequential Drug Release

open access: yesSmall Methods, EarlyView.
MOF‐based magnetic micromotors release two drugs in a controlled and sequential manner at the acidic cancer cell media. Abstract Herein, the synthesis of macroporous zeolitic imidazole framework (ZIF)‐based magnetic micromotors (MMs) for the dual encapsulation of 5‐fluorouracil (5‐FU) and doxorubicin (DOX), with pH‐triggered release is described.

Epistemological Implications of a System—Theoretical Understanding for Sustainability Models

open access: yesSystems Research and Behavioral Science, EarlyView.
ABSTRACT In the sense of the Sustainable Development Goals (SDGs), global efforts to create a sustainable society will not be sufficiently successful under the current geopolitical and socio‐economic trends. For this reason, recent sustainability research has increasingly focused on systemic coherence, the subject of cognition, and psychological and ...

Top‐Level Electromagnetic Design of Multishell Resonant Cavity for Microspherical Microwave Structural Absorbers

open access: yesSmall Structures, EarlyView.
A top‐level design for broadband absorbers is proposed, combining multilayer structures with micro/nanomorphology regulation. Using electromagnetic simulations, controlled fabrication, and numerical analysis, tunable microwave absorption materials are created.

Elementary Students' Metacognitive Knowledge of Epistemic Criteria

open access: yesJournal of Research in Science Teaching, EarlyView.
ABSTRACT Scientific modeling is a core practice of scientific inquiry. Students' engagement in modeling can be enhanced by attending to epistemic criteria, which in science are standards used to evaluate the validity and accuracy of scientific models. While prior research has focused on students' development and use of epistemic criteria in scientific ...
