A unified analytical framework for Mössbauer synchrotron sources

Journal of Synchrotron Radiation, EarlyView.
We present a unified analytical framework for Mössbauer synchrotron and X‐ray free‐electron laser sources that provides exact, rotationally invariant expressions for resonance energies and transition probabilities in mixed magnetic dipole–electric quadrupole interactions without Hamiltonian diagonalization.

What Voting Power Cannot Be

Noûs, EarlyView.
ABSTRACT “Almost everyone,” Ronald Dworkin wrote in Sovereign Virtue, “assumes that democracy means equal voting power.” What, then, is voting power? The standard view defines it as the probability that a vote changes the outcome assuming that each possible combination of votes is equiprobable.

Exploring the Structural, Electronic, and Optical Characteristics of ZrSnO3 Through First‐Principles Calculations for Optoelectronics and Photocatalytic Applications

Electrochemical Science Advances, Volume 6, Issue 4, August 2026.
ABSTRACT We performed first‐principles density functional theory calculations to methodically analyse the structural, mechanical, electronic, thermal, and optical properties of trigonal ZrSnO3 under external pressure up to 60 GPa with GGA‐PBE and HSE06 functionals.

Contrast Agents for Enhanced Bioimaging: A Comprehensive Review

ChemBioChem, Volume 27, Issue 13, 14 July 2026.
Contrast agents, especially those that are nanoparticle‐based, are revolutionizing bioimaging by enabling highly sensitive, specific, and early‐stage diagnosis of diseases like cancer, using clinical imaging modalities such as CT, MRI, PET, and SPECT.

High‐Resolution Laser‐Induced Forward Transfer of Graphene and Graphene/hBN Heterostructures Onto SiN Photodetector Patterns

physica status solidi (a), Volume 223, Issue 13, 8 July 2026.
Laser‐Induced Forward Transfer enables the maskless, high‐resolution integration of graphene and graphene/hBN pixels onto SiN photodetector architectures. Optimized laser processing preserves graphene quality while allowing transfer down to the 15 μm scale and across complex topographies, establishing a selective, mask‐free route toward straightforward
