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.

The dynamics of living and thinking systems, biological networks, and the laws of physics

open access: yesDiscrete Dynamics in Nature and Society, 2004
Discrete chaotic dynamics (DCD) of living and thinking systems are presented in a form of networks of interacting agents with the abilities of energy and information exchange.

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.

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

Bifurcation analysis of the Henon map

open access: yesDiscrete Dynamics in Nature and Society, 2000
Division of the parameter plane for the two-dimensional Hénon mapping into domains of periodic and chaotic oscillations is studied numerically and analytically. Regularities in the occurrence of different motions and transitions are analyzed. It is shown

Classical and quantum chaos in a circular billiard with a straight cut

open access: yes, 1998
We study classical and quantum dynamics of a particle in a circular billiard with a straight cut. This system can be integrable, nonintegrable with soft chaos, or nonintegrable with hard chaos, as we vary the size of the cut. We use a quantum web to show

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 ...

Illuminating Advances in Materials: Optical Physical Unclonable Functions for Security Applications

open access: yesAdvanced Optical Materials, EarlyView.
This review highlights Optical Physical Unclonable Functions (OPUFs) as secure, light‐driven authentication tools. It surveys material platforms including optical fibers, low‐dimensional materials, luminophores, plasmonic nanoparticles and rare earth OPUFs systems.
