Tailored Nanoparticle Organic Network Membranes for Hydrogen Generation
Small, Volume 21, Issue 40, October 9, 2025.Free‐standing nanoparticle organic network membranes (NONM) through a unique covalent chemistry‐inspired liquid‐liquid (L/L) interfacial approach have been developed. The AgNONMs are employed as ready‐to‐use membrane electrodes for the electrochemical hydrogen evolution reaction (HER).

The Political Is Profitable: Political Controversy and Litigation Crowdfunding Outcomes
Politics &Policy, Volume 53, Issue 3, June 2025.ABSTRACT Little research has been conducted on litigation crowdfunding, including how links to politically controversial causes may influence fundraising success. This study collected 500 crowdfunding campaigns for legal expenses initiated between December 27, 2022, and June 1, 2023, and 50 litigation campaigns with the highest fundraising totals on ...

Lorentz Invariance Violation from Gamma-Ray Bursts
The Astrophysical JournalLorentz invariance violation (LV) is examined through the time delay between high-energy and low-energy photons in gamma-ray bursts (GRBs). Previous studies determined the LV energy scale as E _LV ≃ 3.60 × 10 ^17 GeV using Fermi Gamma-ray Space Telescope

Blueprint for a Universal Theory of Learning to Read: The Combinatorial Model
Reading Research Quarterly, Volume 60, Issue 2, April/May/June 2025.The Reading Tree. Abstract In this essay, I outline some of the essential ingredients of a universal theory of reading acquisition, one that seeks to highlight commonalities while embracing the global diversity of languages, writing systems, and cultures.

Small Structures, Volume 6, Issue 4, April 2025.In situ compression tests on the honeycomb structure of Fomes fomentarius hymenium under parallel and transverse loading show that parallel loading results in small and uniform displacements due to hyphae orientation along the honeycomb. Damage occurs through plastic buckling and delamination of tube walls in dry samples.

Artificial Intelligence and Creativity
Philosophy Compass, Volume 20, Issue 3, March 2025.ABSTRACT The question of whether machines can be creative has been at the centre of debates among scholars and practitioners well before the inception of artificial intelligence (AI) as a recognised field of research. This paper reviews how some of the key thinkers in the fields of creativity and AI have approached this question, contextualising their ...

Sub-GeV Gamma Rays from Nearby Seyfert Galaxies and Implications for Coronal Neutrino Emission
The Astrophysical Journal LettersRecent observations of high-energy neutrinos by IceCube and gamma rays by the Fermi Large Area Telescope (LAT) and the MAGIC telescope have suggested that neutrinos are produced in gamma-ray opaque environments in the vicinity of supermassive black holes.

Observations of extragalactic sources with the MAGIC telescope [PDF]
, 2007 MAGIC is currently the world's largest single dish ground based imaging atmospheric Cherenkov telescope. During the first year of operation, more than 20 extragalactic sources have been observed and several of them detected. Here we present results of analyzed data, including discussion about spectral and temporal properties of the detected sources. In

Detection of Cherenkov light from air showers with Geiger-APDs
, 2007 We have detected Cherenkov light from air showers with Geiger-mode APDs (G-APDs). G-APDs are novel semiconductor photon-detectors, which offer several advantages compared to conventional photomultiplier tubes in the field of ground-based gamma-ray ...

Status and results of the MAGIC telescope [PDF]
Journal of Physics: Conference Series, 2008 The MAGIC telescope is an imaging air Cherenkov telescope for very high energy gamma-ray astronomy. The scientific outcome of MAGIC at the end of its second cycle of observations includes outstanding results in both galactic and extragalactic physics. Among them the observation of periodic gamma-ray emission from the galactic binary system LSI+61, an ...
