Direct diamond deposition on a steel surface has been considered very difficult. Recently, we found that high-quality films can be deposited the of stainless-steel X5CrNi 18-10 by drilling multiple regularly arranged pits without interlayers or seeding. The following two hypotheses (A) and (B) as reason why film deposited: unoxidized Cr Ni exposed to prevent carbon diffusion into interior stainless-steel, resulting core generation, Surface geometry with regular roughness contributes stress relaxation delamination prevention. In present study, those have examined quantum chemistry calculation experimental. For calculation, energy barrier kinetic for atom intrudes model cluster calculated an ab-initio computational software package, Gaussian. result supported hypothesis (A). experiment, substrates different characteristics are prepared using various mechanical machining methods used in direct process in-liquid plasma CVD. experimental both (B).

AbstractThis intriguing study aimed to explore the reactivity and structural investigation of (3R,3′R)-2,2′,3,3′-tetrahydroneoprzewaquinone A (THNPQ A) as a potential anti-inflammatory agent. Substantially, electronic properties were investigated using LanL2DZ, 6-311++G (d,p), STO-3G basis sets, with electronegativity values 7.9816, 6.3038, 5.0166 eV, respectively. The natural bond orbital (NBO) analysis calculations optimization energies revealed that LanL2DZ had highest stabilization energy (526.65 kcal/mol) for interaction between πC8-C9 πC3-C4. Regarding nonlinear optical (NLO) properties, (d,p) exhibited averaged polarizability first-order hyperpolarizability values, while anisotropies Δtotal followed order (65.2054 a.u.) > (42.8782 (29.9349 a.u.). Analysis density states (DOS) contribution showed peaks at both occupied molecular (HOMO) (–0.5 lowest unoccupied (LUMO) (0.00 condensed dual descriptors indicated minimal variations in fA– fA+ an increase ΔfA, fA–, following (d,p). sites nucleophilic attack identified O11, O12, O36, O37, which set. Empirical evidence from vitro inhibition assays unequivocally validates potent activity THNPQ A. Particularly noteworthy is its exceptional binding affinity, surpassing diclofenac. By establishing conventional hydrogen bonds glycine COX-I histidine COX-II, exhibits remarkable effective agent combating inflammation. These findings boldly emphasize promising therapeutic prospects field treatment, positioning it compelling candidate further development.Keywords: Anti-inflammatoryDFTmolecular dockingin silicoCOX AcknowledgmentsWe acknowledge Centre High Performance Computing South Africa providing computational resources used this work.Author contributionsE.U.
