UV–Vis absorption spectroscopy, excitation and photoluminescence spectra, as well as IR spectroscopy methods showed that radiation degradation is selective and primarily affects POPOP molecules containing oxazole rings, while pTP demonstrates higher radiation resistance in the initial stages of irradiation. It has been established that at low doses of irradiation, a relative stabilization of pTP luminescence is observed, while the intensity of POPOP radiation decreases already at doses of about 106 rad. Analysis of the difference spectra and the evolution of the IR bands indicates the destruction of C–N and C–O bonds in the POPOP structure, which leads to a disruption of the energy transfer mechanism between the additives and a decrease in the light output of the scintillator. The results obtained allow us to propose a physicochemical mechanism for the radiation degradation of UPS-923A plastic scintillator and can be used in the development of radiation-resistant organic scintillators for high-energy radiation detectors.","PeriodicalId":732,"journal":{"name":"Physics of Wave Phenomena","volume":"34 4","pages":"305 - 311"},"PeriodicalIF":1.1,"publicationDate":"2026-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148909730","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Motivated by these applications, this paper investigates the reflection of plane waves at the boundary of a piezothermoelastic half-space for a traction free surface. A particular focus on the influence of initial stress is examined. Four reflected wave modes such as quasi-longitudinal (qP), quasi-shear vertical (qSV), electrical-acoustic (EA), and thermal (T) are considered. By apply the boundary conditions, a coupled system of linear algebraic equations is obtained. This is solved to express the corresponding amplitude ratios explicitly as functions of the angle of incidence. These expressions are solved by using appropriate mathematical tools, and numerical simulations are conducted for a piezothermoelastic material, such as barium titanate (BaTiO3). The study compares results under two thermoelastic theories: Lord and Shulman (LS) and Green and Lindsay (GL). More energy shifts into the qP wave, while the qSV wave becomes weaker, which helps when a clear qP signal is needed in practical devices. The effects of initial stress on wave behavior are demonstrate graphically and it provides a valuable intuition for smart material design and wave-based sensing technologies.","PeriodicalId":732,"journal":{"name":"Physics of Wave Phenomena","volume":"34 4","pages":"253 - 265"},"PeriodicalIF":1.1,"publicationDate":"2026-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148909732","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unlike the case in traditional membrane approaches, where a gas is passed through a membrane, in this method water is forced through a dry membrane. It is shown that filtering through hydrophilic polyethersulfone membranes with the same nominal pore size does not lead to formation of bubbles. Properties of the resulting nanodispersions are investigated using the dynamic light scattering (DLS), ultramicroscopy, and nanoparticle tracking analysis (NTA) methods. It is found that NBs with a low initial concentration and a hydrodynamic radius of ~50 nm are formed immediately after filtering. Within 10–15 min, the NB concertation increases to a stable level of about 108 particles/mL, and their average size becomes larger. Thirty minutes after generation, the size distribution measured by the NTA method has a maximum at a radius of ~78 nm. Dispersion demonstrates a considerable time stability: after 24 hours the NB concentration remains at a level of ~107 particles/mL. The proposed method is a simple reproducible laboratory technique of producing stable nanobubble dispersions.","PeriodicalId":732,"journal":{"name":"Physics of Wave Phenomena","volume":"34 3","pages":"199 - 205"},"PeriodicalIF":1.1,"publicationDate":"2026-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148394792","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
