Localized Microrobotic Delivery of Enzyme‐Responsive Hydrogel‐Immobilized Therapeutics to Suppress Triple‐Negative Breast Cancer

Small, EarlyView.
In response to enzymatic activity within the tumor microenvironment, remotely actuated microrobots designed for localized delivery of stimuli‐responsive hydrogels engineered to release chemotherapeutics (ChemoBots) are developed. The system leverages magnetic navigation for targeted localization and prolongsed drug release, achieving marked tumor ...

A Comprehensive Analysis of Insight-HXMT Gamma-Ray Burst Data. I. Power Density Spectrum

The Astrophysical Journal
The power density spectrum (PDS) is a powerful tool to study light curves of gamma-ray bursts (GRBs). We show the average PDS and individual PDS analysis with GRB data from the Hard X-ray Modulation Telescope (also named Insight-HXMT).

Controlled Synthesis of Bimetallic Gold‐Silver Nanostars: Atomic Insights and Predictive Formation Model

Small, EarlyView.
A systematic study of gold‐silver nanostars (GNSs) formation reveals the key role of silver and AgCl in directing GNSs growth. Using a rapid and green synthesis approach, temperature and AgNO₃ addition influence the process. This enables control over GNSs morphology, size, and concentration, allowing their properties to be tuned for various fields such

Expansion and Spectral Softening of the Dust-scattering Rings of GRB 221009A

The Astrophysical Journal
An expanding X-ray halo or rings appear when short pulses of X-ray radiation from a background source are scattered by clouds of dust in the Milky Way. We study the X-ray rings of the brightest gamma-ray burst (GRB) 221009A, detected by the Swift X-Ray ...

Passive Ice Protection Systems for Unmanned Aerial Vehicles Applications: A Review

Small, EarlyView.
This review summarizes the recent progress on passive ice protection systems for aeronautical applications, with a particular focus on drones. It provides a general strategy for designing and characterizing an icephobic surface and a state‐of‐the‐art account of icephobic coatings.

Probing Electromagnetic Gravitational-wave Emission Coincidence in a Type I Binary-driven Hypernova Family of Long Gamma-Ray Bursts at Very High Redshift

The Astrophysical Journal
The repointing time of the X-Ray Telescope (XRT) instrument on the Neil Gehrels Swift Observatory satellite has posed challenges in observing and studying the early X-ray emissions within ≈40 s after a gamma-ray burst (GRB) trigger. To address this issue,

A Detailed Time-resolved and Energy-resolved Spectro-polarimetric Study of Bright Gamma-Ray Bursts Detected by AstroSat CZTI in Its First Year of Operation

The Astrophysical Journal
The radiation mechanism underlying the prompt emission remains unresolved and can be resolved using a systematic and uniform time-resolved spectro-polarimetric study. In this paper, we investigated the spectral, temporal, and polarimetric characteristics
