In this work, the synthesis of carbon nanotubes (CNTs) supported sub‐5 nm dominant intermetallic RuCu, RuRh, and RuPd NPs are succeeded by the proposed method of nanosecond laser ultrafast confined alloying (LUCA), which is featured by its unique ultrafast heating and cooling rates and high stability for long‐term alkaline HER catalysis application ...

Congruences for $q$-Lucas Numbers [PDF]
For $\alpha,\beta,\gamma,\delta\in{\mathbb Z}$ and ${\rm\nu}=(\alpha,\beta,\gamma,\delta)$, the $q$-Fibonacci numbers are given by$$F_0^{{\rm\nu}}(q)=0,\ F_1^{{\rm\nu}}(q)=1\text{ and }F_{n+1}^{{\rm\nu}}(q)=q^{\alpha n-\beta}F_{n}^{{\rm\nu}}(q)+q^{\gamma n-\delta}F_{n-1}^{{\rm\nu}}(q)\text{ for }n\geq 1.$$And define the $q$-Lucas number $L_{n}^{{\rm\nu}

In2Se3 Synthesized by the FWF Method for Neuromorphic Computing
The flash‐within‐flash method to synthesize gram‐scale pure phase α‐In2Se3 composed of two vessels: In pellets and Se powder in inner quartz tube, and metallurgical coke in outer quartz tube to introduce indirect heat transfer. The process involves high voltage flashing and results in materials used to generate neuromorphic computing devices ...

A Single‐Stage Differential Amplifier Using Organic Electrochemical Transistors
A three‐transistor differential amplifier using depletion‐mode organic electrochemical transistors is implemented that offers a common‐mode rejection ratio of up to ≈20 dB. Compared to a Wheatstone bridge amplifier, ECG recordings with this amplifier showed improved signal‐to‐noise ratio, gain, and power consumption.

On the independent subsets of powers of paths and cycles
In the first part of this work we provide a formula for the number of edges of the Hasse diagram of the independent subsets of the h-th power of a path ordered by inclusion. For h=1 such a value is the number of edges of a Fibonacci cube.

A Note On Bicomplex Fibonacci and Lucas Numbers [PDF]
In this study, we define a new type of Fibonacci and Lucas num- bers which are called bicomplex Fibonacci and bicomplex Lucas numbers. We obtain the well-known properties e.g. Docagnes, Cassini, Catalan for these new types. We also give the identities of negabicomplex Fibonacci and negabi- complex Lucas numbers, Binet formulas and relations of them.

Based on a simplified version of the morphinan scaffold, 3‐[3‐(phenalkylamino)cyclohexyl]phenol analogues were designed, synthesized and evaluated for their µ‐opioid receptor (MOR) antagonist activity in vitro and in silico. Docking studies indicate a peculiar combination of C‐1 stereochemistry and N‐substitutions as feasibly essential for MOR‐ligand ...

Lucas Numbers with Lehmer Property
A composite positive integer n is Lehmer if (n) divides n-1, where (n) is the Euler's totient function. No Lehmer number is known, nor has it been proved that they don't exist. In 2007, the second author [7] proved that there is no Lehmer number in the Fibonacci sequence.
