Beyond Presumptions: Toward Mechanistic Clarity in Metal‐Free Carbon Catalysts for Electrochemical H2O2 Production via Data Science

open access: yesAdvanced Materials, EarlyView.
Metal‐free carbon catalysts enable the sustainable synthesis of hydrogen peroxide via two‐electron oxygen reduction; however, active site complexity continues to hinder reliable interpretation. This review critiques correlation‐based approaches and highlights the importance of orthogonal experimental designs, standardized catalyst passports ...

Development of dialectical thinking in education

open access: yesСовременное дошкольное образование
Background. The article presented as a discussion brings up the variety of relevant topics on the dialectical thinking formation: “Why is the modern education not interested in developing the dialectical thinking?”; “If based on the dialectical and ...

Limits to the Hall Effect and Other Nonreciprocal Effects in Three‐Dimensional Metamaterials

open access: yesAdvanced Materials, EarlyView.
Comprehensive and fundamental bounds on nonreciprocal effects in three‐dimensional metamaterials are derived. They reveal that the effective Hall mobility cannot exceed the largest constituent mobility, that, under certain conditions, the Verdet constant cannot be enhanced, and that, for constituents with Hall coefficients of the same sign, the largest

When Poor Exciton Dissociation Limits Photocurrents in Organic Solar Cells: Why Low Offset Non‐Fullerene Acceptor Blends Can't Be Efficient

open access: yesAdvanced Materials, EarlyView.
The energetic offset between the donor and the acceptor components in organic photoactive layers is central to the tradeoff between photovoltage and photocurrent losses. This Perspective covers the most important issues surrounding this topic in non‐fullerene acceptor blends, from the difficulty of accurately determining state energies and driving ...

Kilka uwag o logice teologii

open access: yesZagadnienia Filozoficzne w Nauce, 2014
The issue of the logic of theology so far have not been given so much attention neither from logicians nor from theologians. The first group seem not to consider the language of theology as a “place” to apply the results of their work.

To feel, to think and to say : the human con(tra)di(c)tion in Alberto Caeiro

open access: yesÉtudes romanes de Brno
Not without contradiction, the poetry of Alberto Caeiro, of Greco-Pagan aesthetics, which defends the sensitive world as the only reality and insists on the use of the five senses as the only possible way of acquiring knowledge, can only be better ...

Rational Tuning of Hygroscopic Oscillation of Stacked Nanoflake Assemblies for Continuous Ambient Energy Harvesting

open access: yesAdvanced Materials, EarlyView.
Stacked nanoflake assembly (SNA) membranes can oscillate autonomously, offering opportunities for soft actuation and energy harvesting. This work uncovers the physical mechanism behind the sustained oscillation of SNA membranes in gradient humidity and identifies three governing dimensionless parameters, enabling rational design for optimizing SNA ...

Figural concepts in proving by contradiction

open access: yes, 2018
Geometrical thinking in proving by contradiction involves specific and complex processes that can be source of difficulties for students. The goal of this article is to investigate on proof by contradiction in geometry, with particular emphasis on ...

Can Elastomers Combine Stiffness, Toughness and Fatigue Resistance?

open access: yesAdvanced Materials, EarlyView.
This review studies how the molecular and macroscopic architecture of elastomers influence their mechanical properties including: stiffness, stretchability, toughness, fatigue resistance, and damping behavior. By linking the structure to performance, it proposes design principles for advanced elastomeric systems that combine mechanical properties ...
