Eloisa ja erityiseksi tekeminen antroposeenin ajan kasvatuksen haasteena

Kasvatus & Aika, 2022
On kiinnostavaa pohtia, miten voimme kasvatuksella edesauttaa kehystämään materiaalisia kokemuksia osaksi kasvua. Tässä yhteydessä kasvu ei ole riippuvaista ihmiskeskeisistä määreistä tai taidoista, vaan siinä näkyy lasten omalakisen eloisan ...

Revisiting Stability Criteria in Ball‐Milled High‐Entropy Alloys: Do Hume–Rothery and Thermodynamic Rules Equally Apply?

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.
The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

Freehand drawing as a tool for technical resolution: three case studies of contemporary architecture in Paraguay

EGA, 2020
This article is framed within the contemporary architecture of Paraguay and aims to analyze freehand drawing as a tool to transmit technical knowledge between the architect and the craftsman during construction of an architectural work. This process will

Stepwise On‐Surface Synthesis and Transformations of Two‐Dimensional Covalent Organic Frameworks by Controlled Thermal Stimuli

Advanced Materials, EarlyView.
The seminal transformation of a 2D‐COF (SURFCOF‐IMDEA1) into a 2D porous COF (SURFCOF‐IMDEA2) on Au(111) by a sequential C‐C coupling and ladderization triggered by thermal annealing steps at increasing temperatures is reported. Abstract The development of covalent organic frameworks (COFs) is currently a primary objective in materials science, taking ...

La materia en las obras literarias de ficción: una perspectiva de lectores portugueses

Investigación Bibliotecológica: Archivonomía, Bibliotecología e Información, 2021
La determinación de la materia en las obras de ficción es una tarea difícil debido a las especificidades del texto literario. Sin embargo, tal como señalan varios estudios, esta tarea es necesaria y posible de realizar mediante una aproximación a la ...

Microscopic Insights into Magnetic Warping and Time‐Reversal Symmetry Breaking in Topological Surface States of Rare‐Earth‐Doped Bi2Te3

Advanced Materials, EarlyView.
Magnetic doping of the topological insulator Bi2Te3 with erbium adatoms induces out‐of‐plane magnetism and breaks time‐reversal symmetry, opening a Dirac gap and driving a Fermi surface transition from hexagonal to star‐of‐David geometry. Microscopy, spectroscopy, and magnetic dichroism reveal atomically controlled magnetic interactions that tailor the

Resolving the Structural Duality of Graphene Grain Boundaries

Advanced Materials, EarlyView.
Cantilever ncAFM resolves the atomic structure of grain boundaries in graphene, revealing coexisting stable and metastable types. Both contain pentagon/heptagon defects, but metastable GBs show irregular geometries. Modeling shows metastable GBs form under compression, exhibiting vertical corrugation, while stable GBs are flat.

Self‐Cooling Molecular Spin Qudits

Advanced Materials, EarlyView.
A material made of [GdEr] molecular dimers can encode a qudit and perform as a magnetic refrigerant. Microwave resonant pulses coherently manipulate its 16 spin states, while direct demagnetization measurements cool the material and a device down to temperatures below 1 K.

Más allá de lo cuantificable: la materia arquitectónica desde la reciprocidad, elaboración y memoria

[i2]: Investigación e Innovación en Arquitectura y Territorio
Durante años, el discurso sobre la gestión de los recursos materiales en la arquitectura se ha centrado mayoritariamente en indicadores cuantitativos como la huella de carbono.
