Efficient non-linear 3D electrical tomography reconstruction

, 2001
Non-linear electrical tomography imaging can be performed efficiently if certain optimisations are applied to the computational reconstruction process. We present a 3D non-linear reconstruction algorithm based on a regularized conjugate gradient solver ...

Engineering the Electrochemiluminescence Microenvironment: Mechanistic Roles of Nanomaterials in Aptamer‐Based Sensors

Small Structures, Volume 7, Issue 9, September 2026.
This review highlights how nanomaterials have transformed electrochemiluminescence (ECL) aptasensors beyond their traditional role as supports. It examines their emerging roles as new ECL luminophores and active regulators of the ECL microenvironment within aptasensors.

Rapid UAV‐ and Ground‐Based Magnetic Mapping of Subsurface Fractures During a Volcano‐Tectonic Crisis in Grindavík, Iceland

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract We applied an integrated UAV‐ and ground‐based magnetometry workflow to map shallow subsurface fractures and cavities in the town of Grindavík during the 2023–2025 volcano‐tectonic crisis. Short‐wavelength linear and semi‐circular magnetic lows delineate open or partially open fractures and localized cavities, including features with no ...
