Designing Physical Unclonable Functions From Optically Active Materials

open access: yesAdvanced Materials, EarlyView.
Assigning unforgeable “fingerprints” to manufactured goods is a key strategy to fight global counterfeiting. Optical physical unclonable functions (PUFs) are chemically generated random patterns of optically active materials serving as unique authenticators.

Preferential site occupancy of alloying elements in TiAl-based phases

open access: yes, 2016
First principles calculations are used to study the preferential occupation of ternary alloying additions into the binary Ti-Al phases, namely $\gamma$-TiAl, $\alpha_2$-Ti$_3$Al, $\beta_{\mathrm{o}}$-TiAl, and B19-TiAl. While the early transition metals (

Electron Extraction Optimization for Carbon‐Based Hole‐Conductor‐Free Perovskite Photovoltaics With Record 1.41 V VOC

open access: yesAdvanced Materials, EarlyView.
A gradient electron energy level strategy is constructed to reduce voltage losses in planar HTL‐free CsPbI2Br C‐PSCs. This electron extraction optimization enables rapid photogenerated electron extraction and carrier separation, thereby suppressing recombination at the back contact. The resulting PSCs deliver a record VOC of 1.41 V, a high PCE of 17.42%

Disordered Rocksalts as High‐Energy and Earth‐Abundant Li‐Ion Cathodes

open access: yesAdvanced Materials, EarlyView.
Disordered rocksalts with lithium excess (DRX) offer a new direction in Li‐ion cathode design beyond conventional Ni‐ and Co‐based materials. This review highlights the design principles, synthesis strategies, and performance optimization of DRX oxides and oxyfluorides for energy‐dense, sustainable batteries using Earth‐abundant transition metals and ...

Advanced Electrode Materials for Efficient Hydrogen Production in Protonic Ceramic Electrolysis Cells

open access: yesAdvanced Materials, EarlyView.
Protonic ceramic electrolysis cells (PCECs) are a promising intermediate‐temperature hydrogen production technology, leveraging high proton conductivity in electrolytes yet constrained by insufficient catalytic activity and interfacial instability in fuel/air electrodes. This review systematically categorizes advanced electrode materials and critically

Tailoring Gel Polymer Electrolytes for Advancing Quasi‐Solid‐State Batteries

open access: yesAdvanced Materials Interfaces, EarlyView.
A UV‐curable gel polymer electrolyte featuring a PEGDA/PEGMA crosslinked network is developed for quasi‐solid‐state lithium batteries. Tuning the curing time enables enhanced ionic conductivity, Li⁺ transference, and interfacial stability, leading to stable lithium plating/stripping and long‐cycle performance in both half and full cells.

Preferential Membrane Remodeling on Curved Biointerfaces Induced by Conjugated Oligoelectrolyte

open access: yesAdvanced Materials Interfaces, EarlyView.
This study explores how membrane shape influences the interaction of conjugated oligoelectrolytes (COEs) with lipid bilayers. Using a curved biointerface composed of nanobar arrays and supported lipid bilayers, it is revealed that COE intercalation preferentially remodels curved regions, forming distinct structures. These findings highlight the role of

On the Structure–Property Relationship of Semi‐Coherent FeCr2O4/Cr2O3 Spinel/Corundum Interfaces

open access: yesAdvanced Materials Interfaces, EarlyView.
Molecular dynamics simulations of semi‐coherent spinel/corundum interfaces reveals intimate connections between the chemistry of the interface, the misfit dislocation structure, and the properties of these interfaces. In particular, the thermodynamics and kinetics of defects are greatly influenced by the chemistry and structure of the interfaces ...

The Role of Dynamic Solvent Swelling in Electrochemical Doping of Semiconducting Polymers

open access: yesAdvanced Materials Interfaces, EarlyView.
Solvent swelling in organic electrolytes dynamically evolves during electrochemical doping of poly(3‐hexylthiophene) (P3HT); multiple polymers, ranging from highly regioregular to fully regiorandom, demonstrate how crystallinity controls swelling.
