Notes on generalized and extended Leonardo numbers

Notes on Number Theory and Discrete Mathematics, 2023
This paper both extends and generalizes recently published properties which have been developed by many authors for elements of the Leonardo sequence in the context of second-order recursive sequences. It does this by considering the difference equation properties of the homogeneous Fibonacci sequence and the non-homogeneous properties of their ...

Unraveling the Effects of Improved Cooling and Bias Force in the Actuation of a Shape‐Memory Soft Multimaterial Gripper

Advanced Materials Technologies, EarlyView.
This study examines a soft gripper with a NiTiCu6 Shape Memory Alloy (SMA) wire embedded in a graphene nanoparticle (GNP)‐functionalized PDMS matrix. Comparing GNP‐enhanced and plain elastomer prototypes, results show that GNPs improve cooling rates, accelerating release by 40%, but increase energy consumption in low‐current activations.

Chern classes of Schubert cells and varieties

, 2006
We give explicit formulas for the Chern-Schwartz-MacPherson classes of all Schubert varieties in the Grassmannian of $d$-planes in a vector space, and conjecture that these classes are effective.

Tailoring the Electrochemical Performance of SnO2‐Based Anodes for Li‐Ion Batteries: Effect of Morphology and Composite Matrix

Advanced Materials Technologies, EarlyView.
Three different composite anodes, based on SnO2, are investigated as potential anode materials for lithium‐ion batteries. Three different strategies are employed to stabilize SnO2 upon cycling i.e., i) use of an inorganic matrix (TiO2), ii) use of an amorphous carbon matrix, and iii) use of SnO2 with a tailored morphology (nanorod) and a carbon coating.

Exploring the Role of Artificial Intelligence in Precision Photonics: A Case Study on Deep Neural Network‐Based fs Laser Pulsed Parameter Estimation for MoOx Formation

Advanced Photonics Research, EarlyView.
Ultrafast pulsed laser technology enables precise material processing. This study examines molybdenum oxide formation under varying laser parameters. A dataset of 187 samples is generated, and eight deep neural networks (DNNs) with different architectures are trained. Models are validated using three learning rates and evaluated with mean squared error,

Plasmonic‐Hydrogel Hybrid Biomaterials Via In Situ Seeded Growth

Angewandte Chemie, EarlyView.
Detailed chemical analysis of the interactions between Au3+ ions and gelatin‐based hydrogels enables the development of a robust “in situ” seed‐mediated synthesis of plasmonic gold nanoparticles, whereby gold salts are reduced directly on the surface of hydrogel substrates to form the nanostructures.

Enhanced Two‐Photon Excited Emission of Quantum Emitters by Colloidal Plasmonic Metasurfaces

Advanced Photonics Research, EarlyView.
Colloidal plasmonic metasurfaces presenting a completely exposed optical cavity are fabricated via templated self‐assembling silver nanoparticles into squared arrays on top of a thin film of CdSe/ZnS quantum dots. The resulting structure promotes the enhancement of the two‐photon absorption and emission processes of the quantum emitter by exploiting ...
