Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

open access: yesAdvanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Comparative analysis of the Leibniz’s and Wolff’s concepts of system

open access: yesSententiae, 2020
If Wolff from the very beginning was strongly influenced by Cartesianism, and his concept of system was guided by the geometric model of scientific method, Leibniz relies on the German tradition of “methodological thinking”, originated by Joachim Jung ...

Tough, Ductile, and Strong Hard‐Soft Cementitious Composite Enabled by Multi‐Material Additive Manufacturing

open access: yesAdvanced Materials, EarlyView.
Drawing inspiration from the layered hard‐soft architecture found in sea sponges, this work establishes a new framework for architected cementitious composites (ACC) through multi‐material additive manufacturing (MMAM) process. The integration of mortar and elastomer phases into layered architectures enables synergistic toughening mechanisms, including

Highly Anisotropic Quasi‐Direct Organic Metal Halide Hybrids: A Platform for Polarization‐Sensitive Optoelectronics

open access: yesAdvanced Materials Technologies, EarlyView.
One‐dimensional C4N2H14PbBr4 is shown to have a quasi‐direct electronic band structure and strongly anisotropic transport with polarized broadband emission. A GW/Bethe–Salpeter excited‐state force formalism, supported by polarized Raman and temperature‐dependent photoluminescence, identifies low–frequency Pb–Br phonons that drive ultrafast exciton self‐

Fontenelle, l’Académie et le devenir scientifique de la chimie

open access: yesMethodos, 2012
This paper considers Fontenelle’s point of view about the scientific evolution of chemistry in the Academy from the end of the 17th century to the first part of the 18th century. Against the traditional idea that Fontenelle was a Cartesian only concerned

Cartesian Monoids

open access: yesElectronic Notes in Theoretical Computer Science, 2010
AbstractThe Cartesian monoid of partial piecewise shift operators is developed as a model for programming systems such as Backus' FP. Special attention is paid to those elements which are equationally implicitly definable.

Fully 3D‐Printed Wave‐Wound Electromagnetic Motors

open access: yesAdvanced Materials Technologies, EarlyView.
This work presents the first fully 3D‐printed wave‐wound electromagnetic motors, which are created using conductive nanoparticle inks, carbon‐filled nylon polymers, and surface mount components. These motors can achieve a stall torque of 7.62N·mmA−1$7.62 \nobreakspace N{\cdot }mm A^{-1}$ and efficiency of 28.2 %, which approaches the performance of ...

Mare antiquissimum. La réponse de G. B. Vico à la Querelle des Anciens et des Modernes

open access: yesBabel: Littératures Plurielles, 1997
In the beginning of the eighteenth century, when intellectual circles were still ablaze with the quarrel of the Ancients and the Moderns, Italian culture has been confronted with the spread of Cartesian and Port-Royal thought for some years.
