The potential of Euphrates poplar (EP) leaves, a plentiful agricultural waste, as a sustainable adsorbent for wastewater treatment is examined in this work. FTIR, FESEM, and XRD were used to characterize activated carbon (AC) derived from EP leaves by carbonizing them at 400°C for 3 hours. Brunauer found a surface area of 3.77 m²/g using the Brunauer–Emmett–Teller (BET) technique. Methylene blue (MB) adsorption trials showed that with an ideal contact time of 60 minutes, the removal efficiency exceeded 91%. Temperature and pH significantly affected the adsorption process, and the addition of EP nanoparticles enhanced dye uptake. According to kinetic modeling, the Temkin isotherm (R²= 0.904) provided the most accurate equilibrium f

To create nanoparticles of zinc oxide (ZnO), a green chemistry method was used. Using Cordia myxa (ZnO-C) and Ziziphus spina (ZnO-Z) extracts works like natural reduction and stabilization properties. The green process provided enhanced phytochemical interactions, which facilitated nanoparticle formation and improved stability. The concentrations of Zn and O elements were validated using energy-dispersive X-ray spectroscopy. The ZnO-C and ZnO-Z polycrystalline structures with a hexagonal wurtzite phase were validated by X-ray diffraction (XRD), where the average crystalline size is about 17.54 nm for ZnO-C, while for ZnO-Z it is equal to 16.809 nm.

The concept of cubic ideals is an important generalization in an algebraic structure. In this work, we introduce the notion of a cubic Q-sub-algebra and a cubic Q-ideal within a Q-algebra. Some properties of a cubic Q-ideal with a cubic BCK-ideal are studied, and a few results of these ideals are discussed.  Such that every cubic Q-ideal is a cubic BCK-ideal, and the opposite is not true. Also, the concept of the level set of a Q-algebra as a cubic set is defined, and some important results associated with it have been shown. The relationship between a cubic Q-ideal and a Q-ideal with a cubic Q-sub-algebra and a Q-sub-algebra by the level set is proved. Finally, the image and the inverse image of cubic Q-ideals under a homomorphism are

This work revealed the spherical aromaticity of some inorganic E4 cages and their protonated E4H+ ions (E=N, P, As, Sb, and Bi). For this purpose, we employed several evaluations like (0D-1D) nucleus independent chemical shift (NICS), multidimensional (2D-3D) off-nucleus isotropic shielding σiso(r), and natural bond orbital (NBO) analysis. The magnetic calculations involved gauge-including atomic orbitals (GIAO) with two density functionals B3LYP and WB97XD, and basis sets of Jorge-ATZP, 6-311+G(d,p), and Lanl2DZp. The Jorge-ATZP basis set showed the best consistency. Our findings disclosed non-classical aromatic characters in the above molecules, which decreased from N to Bi cages. Also, the results showed more aromaticity in E4 than E4H+

The nature of the dark sector of the Universe remains one of the outstanding problems in modern cosmology, with the search for new observational probes guiding the development of the next generation of observational facilities. Clues come from tension between the predictions from Λ cold dark matter (ΛCDM) and observations of gravitationally lensed galaxies. Previous studies showed that galaxy clusters in the ΛCDM are not strong enough to reproduce the observed number of lensed arcs. This work aims to constrain the warm dark matter (WDM) cosmologies by means of the lensing efficiency of galaxy clusters drawn from these alternative models. The lensing characteristics of two samples of simulated clusters in the Λ warm dark matter and ΛCDM

This study aims to analyze the spectral properties of plasma produced from rice husk(Rh) using the laser breakdown spectroscopy (LIBS) method.

Crypto systems deployed in smart cards and embedded devices are vulnerable to side-channel attacks, in which adversaries exploit power consumption to recover secret keys. Correlation power analysis (CPA) and machine-learning-based attacks can break AES-128 implementations with relatively few traces. This work investigates Neural Signal Obfuscation (NSO) as a practical countermeasure for an AES-128 smart card-style implementation. We first acquire and characterize power traces from the target device and quantify baseline leakage using traces-to-disclosure (TTD), guessing entropy (GE), signal-to-noise ratio (SNR), and the success rate of a neural network attacker. We then design and train a lightweight one-dimensional convolutional obfusca
