Endosomal Escape of siRNA Polyplexes: A Molecular Dynamics Perspective on Underlying Mechanisms
ABSTRACT To achieve a therapeutic effect, nanoparticles delivering nucleic acids must facilitate endosomal escape (EE) of their cargo. Despite extensive research, the mechanisms that lead to an effective EE are not sufficiently understood. Herein, we compare the EE behavior of fo...

Charge Storage and Dark Photocatalysis in Multivariate Ti‐Based Metal‐Organic Frameworks
ABSTRACT “Dark photocatalysis” decouples electron storage from photoconversion, offering a promising route to buffer solar intermittency, however requiring precise control of light‐matter interactions. Metal–organic frameworks (MOFs) provide a platform to tailor these interaction...

Direct Light Storage with Controlled Dark Release in a Bipyridine-Based Covalent Triazine Framework
Abstract Utilizing bifunctional materials capable of direct light-to-charge storage offers an attractive strategy to overcome solar intermittency and enable reliable power supply under dark conditions. Reported bifunctional materials are predominantly based on metal oxides and me...

Thinking (with) Machines: Epistemic Autonomy in Human–AI Interaction
Abstract Generative artificial intelligence has intensified longstanding philosophical questions concerning human cognition and epistemic autonomy. This paper argues that generative AI does not make human beings smarter as such; its epistemic significance depends on how human–AI...

Insights Into the Nature of Quantum Emitters in Electron‐Irradiated Hexagonal Boron Nitride
ABSTRACT Quantum emitters in hexagonal boron nitride (hBN) have emerged as a promising solid‐state platform for quantum technology applications. However, a persistent challenge in the field is the unclear origin of many observed emission lines, particularly in the visible range,...

Disentangling surface and bulk properties of Ta3N5 photoanodes
Abstract Understanding how material and defect characteristics govern photoelectrochemical performance is essential for developing efficient and stable photoelectrodes. Although bulk properties are often emphasized, surfaces and interfaces can equally determine activity and stabi...
