Dominant non-covalent forces in diphenhydramine-8-chlorotheophylline supramolecular assembly
In this study, by applying the principles of the quantum mechanical method, we studied the molecular-level interactions present between two common drugs, namely CTP and DPH, using M062X/cc-pVDZ theory. The interactions were studied at six different sites, thus giving rise to six CTP-DPH complexes using modern computational tools. The binding energies of complexes AF were calculated, and it was shown that the complex formation is thermodynamically favorable. Natural Bond Orbital (NBO) analysis throws light on the inter- and intramolecular interactions present in the complex. To get a detailed idea of the type of interaction, along with its strength, tools such as Quantum Theory of Atoms in Molecules (QTAIM), reduced density gradient approach (NCI-RDG) and Interaction Region Indicator (IRI) were used. The QTAIM parameters, along with the NCI and IRI results, show the presence of weaker interactions such as hydrogen bonds, van der Waals interactions. Focus was also given to analyzing the decomposition of total energy into different components using LED analysis based on DLPNO-CCSD(T) level of theory. The Local Energy Decomposition (LED) analysis goes very well with the binding energy values. The results obtained show that complex F has the highest stability among all the complexes. Also, the results calculated using different methods are consistent, supporting the dominance of weak dispersive forces. Thus, this study gives valuable information related to the interactions between these two drugs, such as their biocompatibility, complexity in pharmaceutical applications. 2026 World Scientific Publishing Company. -

Kitchen Waste Derived Porous Nanocarbon Spheres for Metal Free Degradation of Azo Dyes: An Environmental Friendly, Cost Effective Method
A porous nanocarbon spheres (PNCSs) were prepared from kitchen waste and successfully used for the metal and oxidant free degradation of azo compounds. The PNCSs obtained by the pyrolysis of onion peel, at 1000C, were found to be effective catalysts for the reductive degradation of azo dyes in presence of hydrazine hydrate. The reductive cleavage of azo bonds (N=N) was achieved under microwave irradiation. The degradation process was completed in a span of 1040min; the process was monitored by ultravioletvisible spectroscopy. Fourier transform infrared spectroscopy was also used for the illustration of azo degradation. Interestingly, the reductive degradation of azo dyes produced corresponding amines and they were successfully reused for the preparation of fresh azo compounds. The work, therefore, highlights the valorization of largely produced kitchen-wastes to the sustainable PNCSs and it also provides a platform to demonstrate their applicability as highly cost-effective catalysts for bulk scale chemical transformations.

Porous carbons derived from Arecanut seeds by direct pyrolysis for efficient CO2 capture
In this report, we demonstrate the preparation of a series of carbon nanospheres (CNSs) with high surface area and tunable sizes from natural bioresource, Arecanut kernels, by using direct pyrolysis. This method offers a convenient approach to induce porosity in the synthesized carbons without the need for an activating agent. The textural parameters including the specific surface area, pore volume, and pore size can be controlled by the simple adjustment of the carbonization temperature from 700 to 1000C. The CNSs prepared at 700C showed a low specific surface area, whereas the higher carbonization temperatures (8001000C) supported the rise in specific surface area of the products (433.61001.4 m2/g). The carbon, hydrogen, and nitrogen (CHN) analysis revealed that the CNSs exhibited a high purity with the carbon percentage ranging between 96 and 99%. The synthesized materials were tested as adsorbents for CO2 gas, and it was found that the CNSs with the highest specific surface area of 1001.4 m2/g registered the CO2 adsorption capacity of 14.1 mmol/g at 0C and 30 bar, which is a reasonably high value among reported porous carbons prepared without activation. This value of CO2 adsorption also stands above the activated carbon and multiwalled carbon nanotubes. The excellent CO2 adsorption capability of these adsorbents along with their low-cost synthesis offers a feasible pathway for designing such materials for other applications as well. 2021, Qatar University and Springer Nature Switzerland AG. -
DFT Aware Test Architecture for Communication ICs: ATPG-Based Fault Detection on Lower Technology Node
In this research, hafnium dioxide (HfO2) and titanium dioxide (TiO2) are investigated as advanced gate dielectrics for GaN-based MISHEMTs on diamond substrates. AlGaN/GaN MISHEMTs, incorporating HfO2 and TiO2 as gate dielectrics, have been rigorously analyzed and optimized for RF and DC performance through ATLAS TCAD simulations. The MISHEMTs with HfO2 gate dielectrics exhibited impressive metrics: a high drain current density (IDS) of 3.62 A/mm, a breakdown voltage (VBR) of 998 V, a transconductance (gm) of 1.09 S/mm, and a cutoff frequency (fT) of 49 GHz. Conversely, the MISHEMTs utilizing TiO2 as the passivation layer demonstrated even superior performance, achieving an IDS of 3.7 A/mm, a V_B of 1168 V, a gm of 1.13 S/mm, and an fT of 48 GHz. Both dielectric materials contributed to a notably low on-resistance of 4.9 ?mm. The synergistic effect of the diamond substrate with high-performance HfO2 or TiO2 gate dielectrics positions these MISHEMTs as highly promising candidates for next-generation power switching and RF applications, due to their enhanced efficiency and robustness under high-power and high-frequency conditions. The proposed work improves the performance enhancement of Metal-Insulator-Semiconductor High Electron Mobility Transistors (MISHEMTs) with inclusion of diamond substrate. Diamond substrate to its wide energy bandgap ranges of 5.5 eV for used materials for both power electronics and RF applications electrical and Thermal properties are concerned in its high. 2025, Society for Communication and Computer Technologies.

On the Wave Propagation and Dynamic Response of a Spherical Cavity in Piezoelectric Microstructures via Rabotnov Kernel-Based MooreGibsonThompson Thermoelasticity Theory
This study investigates the transient dynamic response and thermomechanical stability of a transversely isotropic piezoelectric medium featuring a spherical cavity. To accurately model the small-scale effects inherent in advanced structural components, a spatiotemporal nonlocal elasticity framework of the KleinGordon type is employed, incorporating both internal length and intrinsic time scale parameters. The governing equations of the MooreGibsonThompson (MGT) thermoelastic model are reformulated using a nonsingular Rabotnov-type fractional exponential kernel, providing a robust mathematical formulation to capture memory-dependent interactions without the paradox of infinite propagation speeds. The structural boundary of the cavity is subjected to a ramp-type thermal loading and electrical grounding, simulating realistic operational conditions for sensors and actuators. Using the Laplace transform technique and the Zakian numerical inversion method, the transient distributions of temperature, displacement, stress, and electric potential are derived. The results highlight the significant influence of the Rabotnov fractional parameter and spatiotemporal nonlocality on the structural stability and wave-front characteristics. This research provides a unique medium for understanding the latest developments in fractional-order dynamics for piezoelectric micro- and nano-structures, offering practical insights for civil, aerospace, and mechanical engineering applications. 2026 World Scientific Publishing Company. -

The modified nano-CdO/Ag-CdO-carbon paste electrodes were developed for electrochemical detection of mercury (Hg+) heavy metal. The synthesized samples were well characterized through PXRD (Powder X-ray diffraction), SEM-EDAX (Scanning Electron Microscopy-Energy Dispersive X-ray Analysis), XPS (X-ray photo-electron spectroscopy), FT-IR (Fourier transform Infra-Red), and UV-Visible spectroscopy. The Ag-CdO modified electrode endowed with higher sensing current and Csp (188F/g) than pure CdO NPs (94.6F/g) measured by Linear Sweep (LS), Cyclic Voltammetric (CV) and Electrochemical Impedance Spectral (EIS) techniques. The excellent electrochemical sensing action of developed Ag-CdO electrode was examined on heavy metal Hg+ ions at 15 mM scan rate in 0.1M KCl. The linear relationship of sensing measurements with smaller concentration (15 mM) was observed with its increased current (+ 1.64 104 A/cm2 at 1 mM) at 30 mV/s. LOD of CdO and Ag-CdO electrodes (Hg+Oxid) were found at 1.91 mM & 2.41 mM (Hg+Red) respectively with maximum sensitivity at -0.006V. LOQ of CdO and Ag-CdO electrodes (Hg+Oxid) were 5.78 mM & 6.98 mM respectively with maximum sensitivity at -0.006V. The antibacterial measurements of prepared samples were examined for their susceptibility to inhibit the growth of gram-negative (Escherichia coli) and gram-positive (Staphylococcus aureus) bacteria. Thus, the synthesized Ag-CdO electrode provides a new insight for determining the concentrations of critical pollutants and processing the various nanoparticles for sensing of cyanogenic heavy metals.
