Non-Newtonian Pell and Pell-Lucas numbers
Journal of New Results in ScienceIn the present paper, we introduce a new type of Pell and Pell-Lucas numbers in terms of non-Newtonian calculus, which we call non-Newtonian Pell and non-Newtonian Pell-Lucas numbers, respectively.

Dielectric Barrier Discharge Electrothermal Heating and Additive Manufacturing of Thermoset Parts
Advanced Materials Technologies, EarlyView.3D printing of thermosets is difficult due to the low yield stress of most uncured resins. However, by locally heating resin using a non‐equilibrium plasma, layers can be partially cured and printing enabled. Plasma application to a liquid epoxy/carbon nanotube composite is observed to cause rapid surface heating and oxidation of the cured layers ...

Some Identities and Generating Functions for Bidimensional Balancing and Cobalancing Sequences
Universal Journal of Mathematics and ApplicationsThis article studies the bidimensional versions of four number sequences: balancing, Lucas-balancing, Lucas-cobalancing and cobalancing. Some of the identities and generating functions were presented.

The imperfect Fibonacci and Lucas numbers [PDF]
Irish Mathematical Society Bulletin, 2009 A perfect number is any positive integer that is equal to the sum of its proper divisors. Several years ago, F. Luca showed that the Fibonacci and Lucas numbers contain no perfect numbers. In this paper, we alter the argument given by Luca for the nonexistence of both odd perfect Fi- bonacci and Lucas numbers, by making use of an 1888 result of C ...

Advanced Optical Materials, EarlyView.Organic photodetectors (OPDs) based on polymer donor:non‐fullerene‐acceptor (NFA) bulk heterojunction blends offer strong light‐sensing potential, but require methods for optimization. This work demonstrates NFA dilution as an effective strategy to suppress dark current and enable state‐of‐the‐art performance by disrupting NFA crystallinity.

On Sums of Squares of Pell-Lucas Numbers
, 2006 In this paper we prove several formulas for sums of squares of even Pell-Lucas numbers, sums of squares of odd Pell-Lucas numbers, and sums of products of even and odd PellLucas numbers. These sums have nice representations as products of appropriate Pell and Pell-Lucas numbers with terms from certain integer sequences.

Advanced Optical Materials, EarlyView.An optimized fabrication approach for the nanostructuring of optical metasurfaces from van der Waals materials like hexagonal boron nitride is presented. The resonator geometries show enhanced geometric homogeneity, resulting in a significant increase in quality factors of symmetry‐protected bound states in the continuum resonances.
