Newly designed ignition circuit to improve the ignition reliability of Hall thruster

AIP Advances, 2022
This study proposes a newly designed ignition circuit that does not change the ignition starting parameters of a Hall thruster, reduces the critical ignition voltage, and improves ignition reliability. The complexity and weight of the Hall thruster power

Derivation and characterization of retinal pigment epithelium from urine‐derived iPSCs

FEBS Open Bio, EarlyView.
Age‐related macular degeneration causes vision loss via RPE dysfunction and loss. Traditional iPSC therapies rely on invasive biopsies, limiting scalability. Here, we utilize urine‐derived stem cells as an accessible source to generate u‐iPSCs, successfully differentiated into pigmented RPE. This “Urine‐to‐Retina” platform provides a promising path for

Combustion and emissions of gasoline, anhydrous ethanol, and wet ethanol in an optical engine with a turbulent jet ignition system

Proceedings of the Institution of mechanical engineers. Part D, journal of automobile engineering, 2019
Turbulent jet ignition is a pre-chamber ignition system for an otherwise standard gasoline spark ignition engine. Turbulent jet ignition works by injecting chemical active turbulent jets to initiate combustion in a premixed fuel/air mixture.

Electrostatically‐Stabilized PEG‐Free Lipid Nanoparticles for Systemic Nucleic Acid Delivery

Advanced Functional Materials, EarlyView.
This work describes non‐PEGylated layered lipid nanoparticles (nonPEG LLNPs), a gene delivery platform that improves upon standard PEGylated LNPs via electrostatic adsorption of charged polymers. nonPEG LLNPs maintain colloidal stability under biological stresses, enhance circulation time, and mitigate accelerated blood clearance and hepatic ...
