Design and analysis of RbBeBr3−xIx (x=0–3) lead-free perovskites: Tunable mechanical and optoelectronic properties via iodine substitution

Nano Trends
This study presents a first-principles analysis of the structural, mechanical, and optoelectronic properties of the lead-free perovskite series RbBeBr3−xIx (x=0, 1, 2, 3) using density functional theory.

Quantum‐Level Influences on Enzyme Reactions and Their Ripple Effects on Biological Phenomena

Advanced Physics Research, EarlyView.
Because living organisms are ultimately composed of atoms and molecules, quantum‐mechanical effects are expected to contribute to biological phenomena. Quantum biology seeks to elucidate life processes from a quantum‐mechanical perspective. This review discusses how quantum‐level effects, including quantum tunneling, may propagate from enzymatic proton‐

Effect of Sequential and Combined Space‐Based Stressors on Perovskite Solar Cell Stability

EcoEnergy, EarlyView.
A correlation between loss in performance and mobile ion concentration has been established by sequential stressing of perovskite solar cells under Low Earth Orbit conditions with exposure to protons, light, and thermal cycling. It is shown that the loss in performance increases when ion concentration increases and vice versa.

Extreme Optical Field Confinement and Enhancement in a Plasmonic Picopatch Within a Nanoparticle‐on‐Mirror Resonator

Laser &Photonics Reviews, EarlyView.
A picopatch in a plasmonic nanocavity confines the electromagnetic energy to tiny effective volumes, close to 1nm3, leading to extreme electric field enhancements. Furthermore, a clear signature of strong coupling between the picopatch modes and other modes of the structure is obtained, which strongly modifies the far‐field response. ABSTRACT Plasmonic

Probing the QCD θ ¯ $$ \overline{\theta} $$ term with paramagnetic molecules

Journal of High Energy Physics
The experimental search for CP violation in paramagnetic atomic and molecular systems has made impressive progress in recent years. This has led to strong upper limits on the electron electric dipole moment.

HySE: A Force‐Directed Layout Algorithm for Directed and Mixed Graphs

Computer Graphics Forum, EarlyView.
We present HySE, a novel graph layout algorithm for mixed graphs combining directed and undirected components. Using a holistic spring embedder approach, HySE unifies hierarchical and force‐directed aesthetics, supports non‐uniform node sizes, and performs comparably to state‐of‐the‐art algorithms.

Nonhuman Pedagogical Relations: Towards Conceptual Limits

Educational Theory, EarlyView.
Abstract This article considers the pedagogical relation as a relation to a nonhuman educator, wherein the educatee is a member of the Homo sapiens species. My aim is to clarify the extent to which a nonhuman‐human relation can be understood as pedagogical.

Powers That Be: An Adventure in Metaphysics

Philosophical Investigations, EarlyView.
ABSTRACT This paper is an investigation into the increasingly popular trend amongst philosophers on the metaphysics of powers, exemplified by the statement: ‘To be real is to possess a power to affect (or to be affected by) other things’. First, I briefly trace the history of this idea (from the Eleatic dialectic of ancient times to present day quantum
