“Tear‐And‐Stack” Twisted SrTiO3 Moiré Superlattices for Precise Interfacial Reconstruction and Polar Topology

open access: yesAdvanced Materials, EarlyView.
The tear‐and‐stack method enables the creation of twisted SrTiO3 bilayers with accurate twist‐angle control, which yield atomically sharp oxide moiré superlattices with emergent exotic topological polar vortices, thereby opening a new pathway for twistronics based on 2D‐like non‐van der Waals oxides.

The political consequences of gradual engineering in Popper's thought [PDF]

open access: yesKom: Časopis za Religijske Nauke
This article seeks to examine the political consequences of the gradual engineering of Popper's thought. Popper's solution is realistic and intends to reduce problems by giving some power to the state in facing social disasters.

Respect as the Ethic of the Open Society [PDF]

open access: yes, 2006
Karl Popper’s description of the open society in terms of respect, rather than mere tolerance, appears to be highly relevant today. Although he never explicitly addressed the issues of multiculturalism and valuepluralism in contemporary societies ...

Mitigating Singlet Exciton Back‐Transfer using 2D Spacer Layers for Perovskite‐Sensitised Upconversion

open access: yesAdvanced Optical Materials, EarlyView.
The efficiency of bulk perovskite‐sensitised upconversion is hindered by parasitic singlet back‐transfer. A 2D perovskite spacer layer is introduced to weaken this loss pathway by increasing the separation between the sensitiser and the emitter. The spacer layer enhances the upconversion efficiency at lower excitation powers and improves the stability ...

Lügen die Dichter? Poetische und diskursive Er-Kenntnis

open access: yesInternationale Zeitschrift für Kulturkomparatistik, 2019
The article considers the question whether poets lie against the background of the possible difference between poetical and discursive knowledge. Starting from Plato’s thesis, namely that poets lie, the article refers to Rorty, who, in contrast to Plato ...

Accurate masses and radii of normal stars: modern results and applications [PDF]

open access: yes, 2009
This paper presents and discusses a critical compilation of accurate, fundamental determinations of stellar masses and radii. We have identified 95 detached binary systems containing 190 stars (94 eclipsing systems, and alpha Centauri) that satisfy our ...

Recent Advances in Variable‐Stiffness Robotic Systems Enabled by Phase‐Change Materials

open access: yesAdvanced Robotics Research, EarlyView.
Phase‐change materials (PCMs), such as shape memory alloys, hydrogels, shape memory polymers, liquid crystal elastomers, and low‐melting‐point alloys, are driving advancements in stiffness‐tunable robotic systems across a wide range of applications. This review highlights recent progress in PCM‐enabled robotics, focusing on their underlying mechanisms,

Epistemological and ontological indeterminism: Hayek and Schumpeter [PDF]

open access: yesPanoeconomicus
The aim of this article is to compare and contrast the ideas of Friedrich von Hayek and Joseph Alois Schumpeter, who both adopted an indeterminist approach in their economic analyses, through a discussion of their relative strengths and weaknesses.

The platonic foundation of the “Real” Popper by Lawrence Boland [PDF]

open access: yes, 2010
Este trabajo intenta mostrar en qué sentido se puede considerar a Popper como un filósofo platónico. Según Lawrence Boland, Popper se basa en Platón respecto de lo que considera el “verdadero método popperiano”.
