Azaporphyrinoid‐Based Photo‐ and Electroactive Architectures for Advanced Functional Materials

open access: yesAdvanced Materials, EarlyView.
A long‐standing collaboration between the Torres and Guldi groups has yielded diverse azaporphyrinoid‐based donor‐acceptor nanohybrids with promising applications in solar energy conversion. This conspectus highlights key molecular platforms and structure‐function relationships that govern light and charge management, supporting the rational design of ...

Theoretical Study for Cross Sections of Interaction between Vortex γ Photons and Mesoscopic Nucleus Target

open access: yesYuanzineng kexue jishu
In the frontier field of nuclear physics, the interaction between vortex γ photons and nucleus has emerged as a captivating research direction, particularly due to the unique orbital angular momentum (OAM) carried by vortex photons.

High-spin molecular resonances in 12C + 12C

open access: yesEPJ Web of Conferences, 2016
Resonances observed in the 12C + 12C collisions are studied with a molecular model. At high spins J = 10–18, a stable dinuclear configuration is found to be an equator-equator touching one.

The web of three-planet resonances in the outer Solar System II. A source of orbital instability for Uranus and Neptune

open access: yes, 2006
The motion of the giant planets from Jupiter to Neptune is chaotic with Lyapunov time of approximately 10 Myr. A recent theory explains the presence of this chaos with three-planet mean-motion resonances, i.e.

2D MOF with Intrinsic Porosity for Colorimetric Volatile Organic Compounds (VOCs) Detection

open access: yesAdvanced Materials, EarlyView.
An uncommon 2D MOF with intrinsic in‐plane porosity that can be mechanically exfoliated undergoes a distinct and reversible colour change upon exposure to various volatile organic compounds. ABSTRACT In this work, we report an uncommon 2D metal–organic framework (MOF) with intrinsic in‐plane porosity that undergoes a distinct and reversible colour ...

Surprising Spin–Orbit Resonances of Rocky Planets

open access: yesThe Astrophysical Journal
Recent works suggest that, in multiplanetary systems, a close-in exoplanet can sometimes avoid becoming tidally locked to its host star if it is captured into a secular spin–orbit resonance with a companion planet. In such a resonance, the planet remains

Gravitational Interactions and Resonances in Ring-Moon Systems

open access: yes, 2022
While resonances determine the large-scale dynamical structure of planetary systems, interactions among the small bodies in these resonances impact their orbital evolution.

Solvent‐Mediated Reactivity Control of Lewis‐Paired Dopants as a Versatile Strategy for Tunable and Stable Doping of Organic Semiconductors

open access: yesAdvanced Materials, EarlyView.
Solvent‐mediated reactivity control of Lewis‐paired dopants enables highly efficient, finely tunable, and stable doping of organic semiconductors. The optimally doped semiconductor films exhibit superior thermoelectric performance and doping stability, feature delocalized polarons along structurally ordered polymer backbones, and outperform ...

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 ...
