High‐Impulse, Modular, 3D‐Printed CubeSat Electrospray Thrusters Throttleable via Pressure and Voltage Control

Advanced Science, Volume 12, Issue 13, April 3, 2025.
This study reports the proof‐of‐concept demonstration of novel, additively manufactured, droplet‐emitting electrospray emitter arrays for CubeSat thruster applications. The modular thruster design incorporates multiscale features that enable scaling up thrust with low power consumption by employing two different vat photopolymerization technologies, i ...

Pioneering Insights into the Reaction Kinetics of Metastable Intermolecular Composites Based on Metal Fluorides: Virtually non‐existent condensed Phase Combustion Products and Ultra‐Efficient Reactivity

Advanced Science, Volume 12, Issue 14, April 10, 2025.
Novel nano‐thermite designed based on bismuth's low boiling point and the Bi─F bond's low dissociation energy, features enhanced reactivity, minimal condensed phase combustion residues, and self‐pressurization. Its distinctive reaction dynamics facilitate a pre‐ignition stage, resulting in a reduced ignition threshold.

Supramolecular Gels With Controllable Degradation for Suppressing Tumor Recurrence and Relieving Postoperative Pain

Aggregate, Volume 6, Issue 4, April 2025.
A supramolecular gel platform based on poly(ethylene glycol) (PEG) is reported, offering injectability and degradability, with adjustable hydrophilic–hydrophobic ratios to produce RopC Gel for varying pain relief durations. RopC Gel enables sustained release of ropivacaine, induces pyroptosis in melanoma cells, and activates an immune response to ...

Current and potential methods to assess kidney structure and morphology in term and preterm neonates

The Anatomical Record, Volume 308, Issue 4, Page 1229-1250, April 2025.
Abstract After birth, the kidney structure in neonates adapt to the functional demands of extrauterine life. Nephrogenesis is complete in the third trimester, but glomeruli, tubuli, and vasculature mature with the rapidly increasing renal blood flow and glomerular filtration. In preterm infants, nephrogenesis remains incomplete and maturation is slower
