The Topology of Aging: Modeling Elderly Population Dynamics Through Complex Sectoral Networks in Rural Spain

open access: yesGrowth and Change, Volume 57, Issue 2, June 2026.
ABSTRACT This study analyses the socioeconomic interdependence of rural areas by examining whether similarity in primary sector economic structure leads to correlated patterns of demographic aging across municipalities in Northern Spain. We construct an economic network where municipalities are linked based on their proximity in a multivariate space of

Rb4CuSb2X12 (X = Cl, Br) as Novel Vacancy‐Ordered Quadruple Perovskites

open access: yesZeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 7, 6 May 2026.
The vacancy‐ordered quadruple perovskites Rb4CuSb2X12 (X = Cl, Br) were crystallized from hydrohalic acid. Their crystal structures can be interpreted as new distortion variants of the perovskite structure with ordered vacancies. The electronic structure of Rb4CuSb2Br12 shows that the Br and Sb states form the valence band and the upper conduction band.

Thermally Modulated Specular Phonon Transport in a High‐Debye‐Temperature Diamond Nanobeam

open access: yesAdvanced Science, Volume 13, Issue 25, 4 May 2026.
Thermal transport in single‐crystal diamond nanobeams is measured from 140 to 300 K using electro‐thermal micro‐suspended structures. The thermal conductivity shows an increasing deviation from Boltzmann transport predictions assuming fully diffuse boundary scattering at lower temperatures.

Sustainability Assessment of Circular Strategies in the Agri‐Food Industry: The Case of Olive Mills' By‐Product Valorization

open access: yesBusiness Strategy and the Environment, Volume 35, Issue 4, Page 4641-4658, May 2026.
ABSTRACT This study integrates multidimensional sustainability indicators into a unified assessment approach to evaluate circular strategies in agri‐food industry businesses. This methodological approach is applied to empirically examine the case of the olive oil industry's by‐product valorization.

Battery‐Free UV‐Dose Detector via Defect‐Engineered Ca2SnO4:RE (RE = Sm3+, Pr3+) Oxide Phosphors

open access: yesCarbon Neutralization, Volume 5, Issue 3, May 2026.
Sm3+/Pr3+‐doped Ca2SnO4 (CSO:RE) phosphors exhibit orange/deep‐red 4f–4 f emissions and defect‐related luminescence. LPL, TL, and OSL measurements reveal thermally/optically addressable traps, with OSL signals retained after 504 h dark storage. Embedded in a polymer matrix, CSO:RE enables battery‐free UV‐dose logging under sunlight with optical readout,

Depopulation and Longtermism

open access: yes
Abstract This chapter brings facts from population science and population economics into dialogue with longtermism. Many longtermists would agree that, to eventually achieve a flourishing far future, it is valuable that over the coming few centuries a complex global economy endures and the number of people does not become small enough to

Photophysics of Biological and Biomimetic Sunscreen Molecules

open access: yesChemPhotoChem, Volume 10, Issue 5, May 2026.
Recent photochemical and photophysical research into natural and nature‐inspired UV filter molecules is reviewed, with a focus on the application of these systems in next‐generation sunscreens. The results of time‐resolved UV spectroscopy experiments and theoretical studies are discussed.
