Market Participation, Information and Volatility [PDF]

We analyze how the entry of less informed participants in a market for a risky asset affects the volatility of the price of the asset. In an endogenous participation model, we show that in equilibrium the new market entrants are less informed than the ...

Tailor‐Made Protective LixAlSy Layer for Lithium Anodes to Enhance the Stability of Solid‐State Lithium–Sulfur Batteries

Advanced Materials Interfaces, EarlyView.
An intentionally added, chemically formed LixAlSy coating stabilizes the lithium–electrolyte interface in solid‐state Li–S batteries. The layer suppresses side reactions, preserves smooth charge transfer, and improves ion transport from the start. This approach offers a practical route to more durable solid‐state batteries and a clearer understanding ...

Charge Transfer States in Donor–Acceptor Bulk‐Heterojunctions as Triplet–Triplet Annihilation Sensitizer for Solid‐State Photon Upconversion

Advanced Materials Interfaces, EarlyView.
A near‐infrared photosensitizer that facilitates efficient solid‐state photon upconversion by recycling triplets formed within a fullerene‐based donor–acceptor bulk‐heterojunction system is demonstrated. Spectroscopic investigations reveal that the energy of photogenerated charge transfer states of triplet character (3CT) is subsequently transferred to

Laser Micromachining of Liquid Metal Patterns for Stretchable Electronic Circuits

Advanced Materials Technologies, EarlyView.
A cleanroom‐free fabrication strategy combines UV‐laser micromachining with a copper foil wetting layer to rapidly produce high resolution, liquid metal based stretchable electronic circuits on diverse substrates. The scalable, maskless process enables complex circuit designs (<$<$3 h, ∼$\sim$15/device) with excellent electrical stability under strain,

Understanding and Circumventing Failure Mechanisms in Chalcogenide Optical Phase Change Material Ge2Sb2Se4Te

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
Chalcogenide optical PCMs have gathered interest for their potential in compact, non‐volatile optics and photonics. Free‐space PCM metasurfaces require new considerations from phase change memory that need to be addressed for reliable scale‐up. Several failure mechanisms pertaining to free‐space PCM devices and layout methods are isolated to prevent ...

Enhancing Triplet Excitons Lifetime Through Controlled Intermolecular Interactions

Advanced Optical Materials, EarlyView.
Singlet fission (SF) is investigated in pentacene embedded in a surface‐anchored metal–organic framework, enabling a molecular arrangement inaccessible in pure organic crystals. This architecture changes the singlet fission dynamics significantly and enhances the triplet lifetime by almost four orders of magnitude.
