Human Engineered Heart Tissues Reproduce Trigger‐ and Substrate‐Driven Mechanisms of Ventricular Tachycardia

Advanced Science, EarlyView.
Engineered heart tissues (EHTs) derived from human iPSCs replicate mechanisms of ventricular tachycardia at the tissue level. Acquired Long‐QT conditions cause early afterdepolarizations, wavebreak, and transient rotors; in contrast, focal cryoinjury forms a stable substrate that supports ongoing reentry.

BRCA1 Mutation‐Recognizing Tetrahedral Framework Nucleic Acid Nanoplatform Enables Coordinated PARP/WEE1 Inhibition and STING‐Associated Antitumor Immunity in Ovarian Cancer

Advanced Science, EarlyView.
BRCA1 mutation‐responsive FBOA‐tFNA selectively recognizes mutant transcripts and coordinates reduction‐responsive intracellular delivery of olaparib and adavosertib, amplifying DNA damage and weakening G2/M checkpoint protection. These effects are accompanied by STING‐associated immune activation and stronger antitumor immunity, while sequential anti ...

Magnetic Resonance Reveals Radical Stability in Native Biofilms and Its Role in Bacterial Resistance

Angewandte Chemie, EarlyView.
The complex biofilm environment consists of planktonic bacterial cells and cells embedded in an extracellular matrix (ECM). Through an integrated magnetic resonance approach, we show that nitroxide radicals primarily interact with the polysaccharides and lipids in the ECM.

Effect of the hydrophobic fraction and particle size in the collectorless column flotation kinetics

, 1997
In order to investigate the particle size effect of a highly hydrophobic mineral (talc), different size fractions were floated in a column flotation cell to obtain the effect of flotation-rate constants (k) on the kinetics of flotation.

Highly Linear Perovskite Synapses for Neuromorphic Computing

Advanced Science, EarlyView.
Voltage spikes applied to an Au/ACI‐phase perovskite/ITO memristor emulate the ionic signaling of a biological synapse, generating a tunable postsynaptic current. The vertically aligned perovskite film confines iodide‐vacancy migration, enabling highly linear, and symmetric conductance updates with 100 states and 5.5 aJ per event. Such synapses sustain

Natural Anionic Interfacial Reconstruction for Suppressing Pitting Corrosion Enables Durable Seawater Zinc‐Ion Batteries

Advanced Energy Materials, EarlyView.
In situ electrochemically induced molecular sieve‐alginate interface layer can suppress chloride‐induced pitting corrosion, hydrogen evolution, and dendrite growth, while regulating zinc ion transport and deposition, thereby protecting the zinc anode in seawater electrolyte.
