A MATLAB-based effective-medium and transfer-matrix workflow is coupled with a pseudo-first-order kinetic descriptor and a depth-resolved local volumetric rate of energy absorption (LVREA) analysis to estimate how optical thickness, TiO2 content, and Au loading affect near-surface photonic energy deposition. The model-predicted dataset identifies a photocatalytic design window centered at a coating thickness of approximately 0.65–0.75 μm and an Au loading of about 1.0–1.4 vol %, where the balance between plasmon-assisted surface activation, transparency preservation, and parasitic metallic attenuation is most favorable. At the representative optimized point (0.70 μm, 7 vol % TiO2, and 1.2 vol % Au), the simulated apparent rate constant reaches 0.052 min‒1, corresponding to 95.6% MB conversion after 60 min. Higher Au content intensifies near-surface loss and shortens the useful penetration depth, while off-optimum thickness reduces the effective photonic driving force. The results are presented strictly as model-predicted trends intended to guide future experimental validation of transparent photocatalytic and self-cleaning glass coatings.","PeriodicalId":671,"journal":{"name":"Journal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques","volume":"20 3","pages":"718 - 728"},"PeriodicalIF":0.4,"publicationDate":"2026-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149189889","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The calculations are performed using a new technique based on the use of statistics of the discrete process of multiple scattering of an ion beam in a substance and the additive Bragg–Kleeman rule. The comparison of the calculations with the available experimental results indicates the effectiveness of using the new technique in calculating the dependence of the S value of binary hydrocarbons on the ion beam energy. It has been established that the most probable energy losses of ions in these gases are associated not with the ionization of valence electrons of molecules, but with their transfer to metastable states. The energy losses of the beam ions for the transfer of valence electrons of atoms to metastable levels are determined to be ≈9.87 eV in methane, ≈9.46 eV in ethylene, and ≈9.0 eV in acetylene. The data obtained provide the necessary basis for performing reliable calculations of the S values of complex hydrocarbons and organic compounds for directed ion beams of medium and low energies.","PeriodicalId":671,"journal":{"name":"Journal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques","volume":"20 3","pages":"660 - 664"},"PeriodicalIF":0.4,"publicationDate":"2026-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149189951","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The regularities of the Pd → PdO → Pd structural and phase transformations were revealed. Oxidation of epitaxial Pd films produces PdO in two equivalent orientations: (001)[100]PdO ∥ (001)[110]Pd and (010)[101]PdO ∥ (100)[011]Pd. The solid-state reduction of Pd proceeds by an endotaxy mechanism and results in the (112)[11(bar {1})]Pd ∥ (100)[011]PdO orientation. Complete reduction of PdO produces a Pd film with a biaxial texture and a finer grain structure than the initial Pd film. A phase-composition gradient was found in the epitaxial PdO–Pd heterostructure. In this work, an approach using an epitaxial PdO film as an oxidizing substrate for the Li–Nb–O system was applied for the first time. This approach made it possible to achieve LiNbO3 stoichiometry during vacuum annealing and to synthesize a LiNbO3/Pd heterostructure from the initial Li–Nb–O/PdO heterostructure. The results provide prospects for developing new materials and technologies in fields such as microelectronics and nanotechnology, sensing, and catalysis.","PeriodicalId":671,"journal":{"name":"Journal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques","volume":"20 3","pages":"558 - 565"},"PeriodicalIF":0.4,"publicationDate":"2026-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149189818","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
