Rational Device Design and Doping‐Controlled Performance in Fast‐Response π‐Ion Gel Transistors

Advanced Functional Materials, EarlyView.
π‐Ion gel transistors (PIGTs) achieve extraordinary transconductance and stability through device configuration optimization, high‐mobility conjugated polymer selection, and hole scavenger doping. The optimized PIGTs maintain performance on flexible substrates, enabling printed, fast‐response, and wearable electronics.

O Platonismo de Russell na metafísica e na matemática

Kriterion, 2005
Neste artigo, analiso o surgimento e a superação do Platonismo em B. Russell, tanto na sua filosofia da matemática como na sua metafísica. Começo por explicitar os argumentos que levaram Russell a aderir ao chamado "Platonismo Proposicional" - posição ...

Nonstandard logicism

, 2021
Logicism was a dominant position in the foundations of mathematics of the late nineteenth and early twentieth century. Roughly put, it is the view that pure mathematics is reducible to higherorder logic. More specifically, the logicist thesis is usually taken to consist of two claims. First, all primitive terms of an axiomatized mathematical theory can

Near‐Infrared Light‐Programmable Negative Differential Transconductance in Organic Electrochemical Transistors for Reconfigurable Logic

Advanced Functional Materials, EarlyView.
Organic electrochemical transistors based on a Near‐Infrared (NIR)‐responsive polymer p(C4DPP‐T) and iodide electrolyte exhibit optically programmable negative differential transconductance. NIR illumination triggers an iodine‐mediated redox process, enabling a transition from binary to ternary conductance states within a single‐layer device.

Leibniz entre logicisme, formalisme et intuitionnisme ?

Philosophia Scientiæ
Leibniz has often been presented as one of the precursors of logicism or formalism but more rarely a precursor of intuitionism. He was a staunch defender of the Tertium non datur, reasoning in forma and blind thought, so at first glance he appears far ...

Asymmetric Contact Engineering for Bottleneck‐Free Transport in 2D MoS2 Field‐Effect Transistor

Advanced Functional Materials, EarlyView.
Performance of 2D semiconductor transistors is limited by carrier transport bottlenecks arising from specific device geometries. By identifying this structural limitation, a bottleneck‐free asymmetric transistor architecture (BATA) is introduced to improve carrier transport.

Ludwig Wittgenstein e i fondamenti della matematica. Quattro studi: Cantor, Dedekind, il Logicismo, la scoperta in matematica

Nóema, 2013
La critica che Ludwig Wittgenstein muove ai presupposti filosofici del dibattito sui fondamenti della matematica si estende oltre le tematiche specifiche di tale dibattito ed investe un’intera tradizione di pensiero. Dietro alle argomentazioni di Frege e

Trap‐Assisted Transport and Neuromorphic Plasticity in Lead‐Free 2D Perovskites PEA2SnI4

Advanced Functional Materials, EarlyView.
An artificial retina built from lead‐free layered perovskite (PEA)2SnI4 converts light input into a persistent photocurrent and sums successive flashes over time. Micro/nanocrystals integrated on electrodes act as synapse‐like pixels that perform temporal integration directly in hardware. This in‐sensor preprocessing merges detection and computation on

Conceptual thinking in Hegel’s [PDF]

Argument, 2013
Analytical philosophy after Frege’s logicism and Russell’s logical atomism presupposes sortal domains of individual “entities” for which we already have defined their identities and elementary predicates. Such “things” exist only in ideal “possible world”

La naturaleza de la Matemática, sus concepciones y su influencia en el salón de clase

Educación y Ciencia, 2011
Aunque en las últimas dos décadas la situación tiende a cambiar, históricamente se ha tenido la creencia de que para enseñar matemáticas sólo se requiere el buen dominio de los temas, sin tener en cuenta que implícitamente hay una actitud frente a la ...
