Time-averaging Polarimetric and Spectral Properties of Gamma-Ray Bursts
The Astrophysical Journal Supplement SeriesThe composition and radiation mechanism of gamma-ray bursts (GRBs) within jets continue to be hotly debated. Investigating the joint polarimetric and spectral properties is crucial for understanding the composition and radiation mechanism of GRBs ...

The Effect of Amino Acids on the Formation of Amorphous Calcium Carbonate Nanoparticles
Advanced Functional Materials, EarlyView.Biomineral formation often proceeds via the assembly of amorphous calcium carbonate (ACC) nanoparticles with narrow size distributions. Using in situ SAXS coupled to a stopped‐flow device, we follow synthetic ACC formation with a 10 ms time resolution and show that amino acids narrow the size distribution at low supersaturation, highlighting their key ...

Choked Jets and Low-Luminosity Gamma-Ray Bursts as Hidden Neutrino Sources [PDF]
, 2015 We consider gamma-ray burst (GRB) jets that are choked by extended material as sources of high-energy cosmic neutrinos. We take into account the jet propagation physics both inside the progenitor star and the surrounding dense medium.

Facile Deep Brain Electrode Coating with MXene for Improved Electrode Performance
Advanced Healthcare Materials, EarlyView.Facile dip‐coating of commercial carbon fiber electrodes with Ti3C2Tx MXene improves electrical conductivity, reduces impedance, and enables single‐neuron recordings in the rat hippocampus over four weeks. The coating maintains biocompatibility, minimizes inflammation, and remains MRI‐compatible.

Exploring Physically Motivated Models to Fit Gamma-Ray Burst Spectra
The Astrophysical Journal, 2023 We explore fitting gamma-ray burst (GRB) spectra with three physically motivated models, and thus revisit the viability of synchrotron radiation as the primary source of GRB prompt emission. We pick a sample of 100 bright GRBs observed by the Fermi Gamma-
