Quantifying Electron and Ion Transfers in Contact Electrification with Ionomers

Advanced Functional Materials, EarlyView.
The concurrent existence of both electron and ion transfers in solid‐ionomer contact electrification is reported. The ion transfer contributes significantly to the process of contact electrification, especially at high humidity, although only less than 2% of ions participate in the ion transfer, suggesting that there is room for further performance ...

Structural changes in chemically deposited CdS: effect of thermal annealing

Moldavian Journal of the Physical Sciences, 2010
The dynamics of changes in the structural and optical properties of chemical bath- deposited (CBD) CdS/glass thin films in H2 annealing process in a pre-heated furnace between 200–450°C was studied systematically. Annealing imparts structural stability

Scalable Perovskite Quantum Dot Glass Nanocomposites for High‐Efficiency Luminescent Solar Concentrators

Advanced Functional Materials, EarlyView.
This study evaluates the scalability of PQD GNC‐based LSCs for BIPV applications. Experimental data and Monte Carlo simulations predict performance up to 1 m2, achieving a peak power conversion efficiency of 3.17%. The results confirm the viability of these LSCs for energy‐efficient building applications.

Hardness fluctuations caused by annealing in Zr-based bulk metallic glasses via nanoindentation

Journal of Materials Research and Technology
The micromechanical response of a Zr-based bulk metallic glass (BMG) annealed in air below and above its glass transition temperature was studied. Nano-sized particles in different states at different annealing temperatures were found on the surface of ...

The paramagnetic and glass transitions in sudoku

, 2012
We study the statistical mechanics of a model glassy system based on a familiar and popular mathematical puzzle. Sudoku puzzles provide a very rare example of a class of frustrated systems with a unique groundstate without symmetry.

Molecular‐Level Dual‐Ionophilic Passivation for High‐Areal‐Capacity Lithium Metal Anodes on Nanostructured Paper Electrodes

Advanced Functional Materials, EarlyView.
The effect of a molecular‐level dual‐ionophilic chitosan passivation layer is investigated on a nanostructured paper electrode featuring an interconnected network structure of highly oxygen‐functionalized single‐walled carbon nanotubes (C‐NPE). This molecular coating enabled a high Coulombic efficiency (>99.0%) and stable cycling over 350 cycles at an ...

From metallic glasses to nanocrystals: Molecular dynamics simulations on the crossover from glass-like to grain-boundary-mediated deformation behaviour

, 2018
Nanocrystalline metals contain a large fraction of high-energy grain boundaries, which may be considered as glassy phases. Consequently, with decreasing grain size, a crossover in the deformation behaviour of nanocrystals to that of metallic glasses has ...

Self‐Reinforcing Degradation of Solution‐Processed Small‐Molecule OLEDs: Excited‐States and Molecular Interactions as Key Triggers

Advanced Functional Materials, EarlyView.
Self‐reinforcing degradation in solution‐processed small‐molecule organic light‐emitting diodes (OLEDs) arises from charge accumulation and exciton‐polaron interactions, leading to molecular aggregation and efficiency loss. This study uncovers the fundamental mechanisms behind this degradation and introduces strategic material engineering approaches ...
