Thermally Induced Gelling Systems Based on Patchy Polymeric Micelles
Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.A novel strategy to design thermally induced gelling systems with tunable material properties is reported. Polymeric mixed‐shell micelles displaying multiple thermosensitive patchy domains formed hydrogels by assembling into well‐entangled worm‐like network structures upon heating to body temperature. The patchy micelle design significantly affects the

Ultrahigh Piezoelectricity in Truss‐Based Ferroelectric Ceramics Metamaterials
Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.By leveraging the unique combination of polarization direction and loading state, ultrahigh piezoelectricity is achieved through careful tuning of the relative density and scaling ratio in truss‐based ferroelectric metamaterials. This approach enables the simultaneous realization of extremely high piezoelectric constants and ultralow dielectric ...

Students’ proof schemes for mathematical proving and disproving of propositions
The Journal of Mathematical Behavior, 2016 Abstract Classification of students’ proof schemes offers insights into students’ mathematical proving. However, previous studies revealed little about finer progressions in students’ proving and barely examined their proof schemes involving counterexamples.

The probability scheme of constructing the mathematical model of shadowed sputtering
Computer Physics Communications, 2000 The probability scheme of examination of the shadowed vacuum sputtering process is suggested. If one restricts the consideration by non-scattering part of the scheme the resulting model would be equivalent to geometro-optical shadowing model used by our predecessors. At the same time the scheme gives the possibility for the model improvement.

Print‐and‐Plate Architected Electrodes for Electrochemical Transformations Under Flow
Advanced Functional Materials, EarlyView.Typical flow cell electrodes are composed of stochastic porous carbon, limiting understanding of electrode structure‐performance relationships. This work describes an approach, termed “print‐and‐plate,” to prepare porous electrodes by direct ink writing followed by conformal metal coating.
