Potent Liver‐Tropic mRNA Lipid Nanoparticles: ApoE‐Mediated Delivery Through a Low‐Density Lipoprotein Receptor Independent Uptake Mechanism

Advanced Materials, EarlyView.
Helper and ionizable lipids play a crucial role in determining ApoE binding and subsequent liver tropism and LDLR‐mediated uptake. Ionizable lipids primarily govern the LDLR‐independent uptake pathway. This complementary interplay between lipid components ultimately governs LNP delivery performance and therapeutic efficacy in the liver.

De Rerum Natura: How Do Halide Perovskites Self‐Heal From Damage?

Advanced Materials, EarlyView.
How can lead‐halide‐perovskites self‐heal after damage from light, heat, mechanical strain, or radiation? We show that reversible chemical defects underly performance losses and recovery, highlighting the roles of halide and proton migration, redox‐driven reactions, and acid‐base equilibria.

Ultrasound‐Responsive Dual‐Prodrug Nanoassembly for “Fenestrae‐Restoration Strategy” in Liver Fibrosis Therapy

Advanced Materials, EarlyView.
ABSTRACT Liver fibrosis is a serious yet reversible intermediate stage in the progression of liver disease, which can ultimately advance to cirrhosis and hepatocellular carcinoma. Targeted and selective inhibition of activated hepatic stellate cells (aHSCs) has emerged as a promising therapeutic strategy for the treatment of liver fibrosis.

2D MOF with Intrinsic Porosity for Colorimetric Volatile Organic Compounds (VOCs) Detection

Advanced Materials, EarlyView.
An uncommon 2D MOF with intrinsic in‐plane porosity that can be mechanically exfoliated undergoes a distinct and reversible colour change upon exposure to various volatile organic compounds. ABSTRACT In this work, we report an uncommon 2D metal–organic framework (MOF) with intrinsic in‐plane porosity that undergoes a distinct and reversible colour ...

Measuring system for partial discharge

Quality Measurement: The Indispensable Bridge between Theory and Reality (No Measurements? No Science! Joint Conference - 1996: IEEE Instrumentation and Measurement Technology Conference and IMEKO Technical Committee 7. Conference Proceedings, 2002
Measuring of the partial discharge (PD) parameters of the insulating systems is very important. The prompt insulating system estimation and its remaining life time give the great savings. The new, complex PD measuring methods are now developed in the world because conventional methods do not give valid information of the insulating system conditions ...

Partial Discharge Measurement

2014
This chapter is devoted to the measurement of partial discharges (PD) localized in weak spots of dielectrics if subjected to high test voltages. As standards for PD measurement s have been introduced only for quality assurance tests of HV apparatus energized by power frequency AC voltages (50/60 Hz), the following treatment refers mainly to this test ...
