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}

The defect sizes can vary from parts of a nanometer to hundreds nanometers when nanobubbles are formed in the liquid. The salt ions can be localized both in the bulk phase and close to defects and water–air interfaces, which corresponds to the formation of their bulk and surface hydration structures respectively. Depending on the water : salt molar ratio and the character of the ion hydration, coordination bonds between the ions and closest water molecules are characterized by different effective electronic charges and, hence, different strengths, which is reflected in the vibrational states of the molecules and their infrared absorption spectra in the high-frequency range. Nonempirical simulations carried out for the X(H2O)n clusters (where X = Na+ or Cl– and n ≤ 55) at the DFT-B3LYP/6-31G(d, p) level were used for predicting the absorption spectra of the ionic systems. The results show that the surface and bulk hydration structures of both ions differ in the intensities of spectral signals depending on the frequency subranges, which can be used as indicators of the changing fractions of the bulk and surface hydration structures of the ions particularly reflecting the role of nano-scale defects close to which the ions can be localized in the dynamic structure of the solution.","PeriodicalId":732,"journal":{"name":"Physics of Wave Phenomena","volume":"34 3","pages":"186 - 198"},"PeriodicalIF":1.1,"publicationDate":"2026-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148394791","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}

About 20 years ago, technologies for high-sensitivity spectroscopy in the THz range appeared. The most advanced method is the THz time-domain spectroscopy (THz-TDS). The application of THz spectroscopy in biology has proved to be extremely productive. This is due to the fact that water is an integral component of any biological object, and the THz range has the greatest sensitivity to the intermolecular structure and dynamics of water. It turned out to be possible to study the molecular objects contacting water by analyzing this water. All research in this field can be divided into two areas. The first, to which main attention has been paid, is devoted to the development of THz methods for medical diagnostics. Much has been done in this area, but so far these technologies have not been introduced into widespread medical practice. The second (fundamental) direction is the study of hydrate shells of biomolecules. Fundamentally new data have been obtained in this field, which showed a much greater extent and greater importance of hydrate shells for biological processes than was previously suggested. Both areas logically fit into a new scientific field: THz biophotonics. This review summarizes the main achievements in this line of research. Attention is drawn to the fact that the main target of THz biophotonics is water. It is the spectral manifestations of water in various biological objects that are the main material for analysis in both applied and fundamental research.","PeriodicalId":732,"journal":{"name":"Physics of Wave Phenomena","volume":"34 3","pages":"161 - 174"},"PeriodicalIF":1.1,"publicationDate":"2026-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148394787","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}
