Full-Stokes, Multi-Frequency Radio Polarimetry of Fermi Blazars; Monitoring and Modelling
Galaxies, 2017 The polarised emission from active galactic nuclei (AGN) jets carries information about the physical conditions at the emitting plasma elements, while its temporal evolution probes the physical processes that introduce variability and dynamically modify ...

Heterogeneous Nanopore Arrays – Selective Modification of Nanopores Embedded in a Membrane
Advanced Materials, EarlyView.Biological processes rely on the concerted action of channels with different functionalities embedded in the same membrane. Inspired by nature, heterogeneous nanopore arrays are prepared where two nanopores are connected in parallel and function as two different elements of an ionic circuit: a diode and a resistor.

Space-based aperture array for ultra-long wavelength radio astronomy [PDF]
, 2015 The past decade has seen the advent of various radio astronomy arrays, particularly for low-frequency observations below 100 MHz. These developments have been primarily driven by interesting and fundamental scientific questions, such as studying the dark

Advanced Materials, EarlyView.A spin reorientation transition is generated at hybrid interfaces of Pt‐Co‐organic molecules in the vicinity of room temperature. This spin reorientation transition happens at an ultrafast scale and is controlled either through electrical current or fs laser pulse, introducing perpendicular magnetic anisotropy in formerly planar magnetised samples ...

Advanced Materials, EarlyView.This study reveals an atomic‐level correlation between bulk dislocations and the exsolution of surface nanoparticles through a novel approach for dislocation engineering in epitaxial thin films. Employing in situ scanning transmission electron microscopy, two primary reasons for the frequent nucleation of dislocation‐associated nanoparticles are ...

HZO/HSO Superlattice ReFET Array Integrating Optical Sensing for Neuromorphic Vision Computing
Advanced Materials, EarlyView.A photonic ReFET array with an engineered HZO–HSO superlattice enables monolithic integration of optical sensing, nonvolatile memory, and synaptic computation. It exhibits forming‐free, >8‐bit analog states, >1010 endurance cycles, and light‐tunable conductance.

Advanced Materials, EarlyView.TiC Colloidal variants are synthesized via a green and waste‐free laser fragmentation technique. The surface and elemental composition of the TiC colloids are tuned through laser‐induced carbon nucleation and nitridation while maintaining their crystal integrity. These changes maximize light–colloid interactions, thereby improving photo thermalization.
