Stereospecific Assembly of Triply Chiral Pseudopeptidic Cages Through Dynamic Dual Chirality Transfer

open access: yesAngewandte Chemie, Volume 138, Issue 11, 9 March 2026.
The spontaneous assembly of triply chiral (L, Δ, P or D, Λ, M) cages has been achieved from a simple tripodal chiral effector based on phenylalanine tris(amidoamine), non‐chiral bipyridine dialdehyde, and a metal ion. Orthogonal imine bond and iron (II) coordination generate a single combination of chiral elements, while configurationally stable ...

From credits to coherence: Applying the policy coherence approach to prevent problem‐shifting in the Paris Agreement Crediting Mechanism

open access: yesReview of European, Comparative &International Environmental Law, EarlyView.
Abstract Carbon crediting mechanisms can deliver cost‐effective climate mitigation but risk ‘problem‐shifting’ by worsening environmental harms such as biodiversity loss and water pollution. This article assesses whether the Paris Agreement Crediting Mechanism (PACM) is better equipped than the Clean Development Mechanism (CDM) to prevent such trade ...

The Role of Political Actors in Realizing Sustainable European Energy Markets: Insights From the Trinational Upper Rhine Region

open access: yesRegulation &Governance, EarlyView.
ABSTRACT Against the background of the European decarbonization strategy, this study examines the extent to which the expansion of renewable energies can lead to tensions with the social and ecological dimensions of the sustainability concept. The study is based on qualitative interviews with 66 experts conducted in the trinational metropolitan region ...

Stratospheric Aerosol Particle Size Explains Divergent Limb and Solar Occultation Measurements After the Hunga Eruption

open access: yesGeophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The 2022 Hunga eruption significantly perturbed the stratosphere by injecting substantial water vapor and SO2 ${\text{SO}}_{2}$, drastically changing the Aerosol Optical Depth (AOD) and particle size. Post‐eruption, satellite limb‐scattering retrievals of aerosol extinction from Ozone Mapping and Profiler Suite Limb Profiler (OMPS‐LP) and ...

Search for neutrino radiative decays during a total solar eclipse

open access: yes, 2004
We present the results of the measurements performed in the occasion of the 2001 total solar eclipse, looking for visible photons emitted through a possible radiative decay of solar neutrinos.

Steady Collapse of Uranus' Exosphere After 1998 to the Present Decade

open access: yesGeophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Uranus' thermospheric temperature decreased from ∼800K in 1986 to ∼450K in 2022 as determined from observations of H3+ and H2 infrared emissions. Spitzer 2007 lower atmosphere observations do not emulate this cooling trend. Here we show that the atomic H Lyman ⍺ emission from the disk of Uranus observed by HST from 2011 to 2022 are not ...
