The S-box is a vital component for producing nonlinearity in a block cipher. Seldom this component is constructed through finite fields; however, sometimes Galois rings are used for its construction. In this work, we utilize the extended Galois ring to construct a Substitution box (S-box) over the ring GR4,4[x]

Significantly reduced band gap (2.0 eV) zinc sulphide (ZnS) nanoparticles are synthesized using microwave/ultraviolet/ultrasonic assisted hydrothermal route in a two step process. Initially, ZnS nanospheres are synthesized, showing a cubic structural phase with a band gap of 3.2 eV, which is further annealed at 1000 °C to get the final product. Fol...

Self-avoiding walks are studied on the 3-simplex fractal lattice as a model of linear polymer conformations in a dilute, nonhomogeneous solution. The model is supplemented with bending energies and attractive-interaction energies between nonconsecutively visited pairs of nearest-neighboring sites (contacts). It captures the main features of a semi-...

The current study comprises the changing surface morphology of austenitic stainless steel (SS-316) with WC-10Co4Cr powder using an affordable microwave route. The surface modification was achieved by utilizing a microwave apparatus (power: 1.2 kW; frequency: 2.45 GHz). The x-ray diffraction (XRD) study reveals the presence of various carbide phases...

When the balance number is greater than one, the modified simple equation (MSE) method typically fails to yield analytical wave solutions for nonlinear evolution equations (NLEEs) that appear in engineering and mathematical physics. We have addressed this shortcoming in this article and established a technique to implement the MSE approach to inves...

In this study, modified epoxy nanocomposite was produced by incorporating SiO2 nanoparticles of 15–30 nm in size, with different concentrations ranging from 1 to 20 wt%. The electrical properties of the epoxy nanocomposite were measured at room temperature in the frequency range of 10−2–107 Hz. To determine the impact of nanoparticles on the epoxy ...

In this study, we developed a simple surface-enhanced Raman Scattering (SERS) composite substrate, composed of an all-metal metasurface and on-surface random distributing silver nanoparticles (AgNPs), to enhance the performance of SERS sensing. The metasurface is made up of gold (Au) nanopillars array on aluminum (Al), it can localize the electroma...

To generate dual combs for various precision measurements, the temporal evolution and spectral characteristics of dual fields in a double-pumped microcavity are investigated. Results show that by using dual orthogonally polarized pumps, the dual fields can be controlled by regulating the two detunings. The coexistence of solitons and Turing pattern...

In this manuscript, we present a negative capacitance TFET with extended back gate-drain overlap (DEBG-NC-TFET) to enhance DC and analog/high frequency (HF) performance. TCAD-based simulations reveal that DEBG-NC-TFET offers a significant enhancement in ION and SS because of a Ferroelectric (FE) layer introduced into the gate-oxide layer of the dev...
