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.

Free‐Standing Supramolecular Pyridine N‐Oxide‐Silver(I) Metallogels

open access: yesAdvanced Materials, EarlyView.
A comprehensive analysis of pyridine N‐oxide‐silver(I) trifluoroacetate complexes reveals remarkable mechanical strengths that enable the creation of free‐standing objects with shape control, reaching dimensions of up to centimeters and shedding new insights into the gelation mechanisms.

Chaotic Orbits in Thermal-Equilibrium Beams: Existence and Dynamical Implications

open access: yes, 2003
Phase mixing of chaotic orbits exponentially distributes these orbits through their accessible phase space. This phenomenon, commonly called ``chaotic mixing'', stands in marked contrast to phase mixing of regular orbits which proceeds as a power law in ...

Transparent, Sprayable Plastic Films for Luminescent Down‐Shifted‐Assisted Plant Growth

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
Spreading the light: A modular approach to down‐shifting europium‐containing polyoxotitanium luminescent cages is developed, allowing their incorporation into sprayable plastic coatings on agricultural greenhouses for accelerated plant growth. Abstract The world's steadily growing population and global heating due to climate change are a threat to food

Statistics of Chaotic Resonances in an Optical Microcavity

open access: yes, 2016
Distributions of eigenmodes are widely concerned in both bounded and open systems. In the realm of chaos, counting resonances can characterize the underlying dynamics (regular vs.

Oligomerization‐Induced Supramolecular Glass with Superior Processability and Optical Functions

open access: yesAdvanced Optical Materials, EarlyView.
Oligomerization‐induced supramolecular glass (BGG) is formed via a catalyst‐free melt‐quenching strategy from benzoguanamine. The in situ formation of diverse oligomers suppresses crystallization, enabling glass formation. BGG exhibits a high Tg (100.1 °C), polymer‐like modulus, and bright aggregation‐induced emission, and is readily processed into ...

Weak-Localization in Chaotic Versus Non-Chaotic Cavities: A Striking Difference in the Line Shape

open access: yes, 1994
We report experimental evidence that chaotic and non-chaotic scattering through ballistic cavities display distinct signatures in quantum transport. In the case of non-chaotic cavities, we observe a linear decrease in the average resistance with magnetic

DNA Code Design Based on the Bloch Quantum Chaos Algorithm

open access: yesIEEE Access, 2017
The design of DNA codes sets satisfying certain combinatorial constraints is important in reducing hybridization errors due to nonspecific hybridization between distinct codes and their complements in DNA computing, data encryption, and data storage. The

On Expectation Correlate System and Chaotic Dynamics in Time-Series [PDF]

open access: yesAl-Rafidain Journal of Computer Sciences and Mathematics, 2004
This paper suggests a new system of time-series called  Expectation Correlate System (ECS) that are good at detecting the behavior of  dynamical  systems (both deterministic and stochastic systems) and the dependence on initial values.
