Facile Single‐Nanocomposite 4D Bioprinting of Dynamic Hydrogel Constructs with Thickness‐Controlled Gradient

open access: yesAdvanced Science, EarlyView.
This study presents a novel and facile thickness‐modulated 4D bioprinting approach using a smart bioink made of gelatin, GelMA, and MXene. Leveraging computational models, it creates living constructs with programmable unidirectional and bidirectional curvatures under a single UV exposure.

Educação bancária: uma questão filosófica de aprendizagem

open access: yesRevista Educação e Cultura Contemporânea, 2011
Este artigo pretende discutir a ideia de Educação Bancária a partir da reflexão filosófica da aprendizagem. Entende-se aprendizagem como resultado de aquisições que transformam o sujeito e o papel do professor no processo de aquisição da aprendizagem é ...

An Enduring Philosophical Agenda. Worldview Construction as a Philosophical Method\ud [PDF]

open access: yes, 2007
Is there such a thing as a philosophical method? It seems that there are as many philosophical methods as there are philosophies. A method is any procedure employed to achieve a certain aim.

Pre‐Torsion Tubular Metamaterials: Multi‐Effect Integration for Advanced Functional Applications

open access: yesAdvanced Science, EarlyView.
Through a pre‐torsion design paradigm, the authors design and fabricate a class of multi‐effect mechanical metamaterial that synergistically integrates compression‐torsion and auxetic behaviors over an extensive strain range, and their formation mechanisms are quantitatively analyzed and elucidated via experiments and finite element methods.

Exponentially Modified QCD Coupling

open access: yes, 2007
We present a specific class of models for an infrared-finite analytic QCD coupling, such that at large space-like energy scales the coupling differs from the perturbative one by less than any inverse power of the energy scale. This condition is motivated

Critical Assessment of Contact Resistance and Mobility in Tin Perovskite Field‐Effect Transistors

open access: yesAdvanced Electronic Materials, EarlyView.
Contact resistance and field‐effect transistor (FET) mobility of Cs0.15FA0.85SnI3 tin perovskites are determined using gated four‐point‐probe (4PP) FET measurements in a Hall bar geometry. The results indicate that contact resistance can significantly impact transistor characteristics, often leading to underestimation or overestimation of FET mobility ...

We the People : John Locke, Collective Constitutional Rights, and Standing to Challenge Government Action [PDF]

open access: yes, 1985
The Article is presented in three Parts. Part I documents the enormous effect that Locke\u27s political philosophy had on the Constitution\u27s Framers and traces the idea of collective rights through Locke\u27s Second Treatise, showing how Locke viewed ...

Understanding the Interplay Between Thermal Activation, Diffusion, and Phase Segregation of Molecular Dopants Blended with Polymeric Semiconductors

open access: yesAdvanced Electronic Materials, EarlyView.
The use of air stable but thermally labile molecules provides an efficient strategy for the N‐type doping of organic semiconductors with relatively low electron affinities. Design criteria for efficient dopants should also take into account diffusion and phase segregation that cannot be decoupled from thermally activated doping.
