The radiant power paradox is the dilemma of whether electrodynamic systems radiate power outward or not. Mathematical analysis of the microscopic Maxwell equations describing excitation and propagation of electromagnetic fields shows that the total radiant power should be zero, whereas many classical problems considering localized currents argue the opposite. The paradox is resolved by proving limited applicability of localized-current models to calculations of energy and momentum characteristics of electromagnetic fields. The nonzero value of the total radiant power for these currents turns out to be the localized current approximation error, while the true radiant power value is always zero for physically consistent excitation currents. On the basis of analysis of physically consistent currents, an improved model of localized currents is proposed that enables physically consistent description of electromagnetic fields from the viewpoint of their energy and momentum characteristics but at the expense of causality violation in the external current-free region.","PeriodicalId":732,"journal":{"name":"Physics of Wave Phenomena","volume":"33 3","pages":"214 - 220"},"PeriodicalIF":1.1,"publicationDate":"2025-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145167770","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}

Of particular interest is the formation of condensed phases from an aqueous solution of colloidal particles on a substrate in an external rotating magnetic field. Substrate defects (for example, the substrate roughness) are of great importance in an experiment. These defects can act as pinning centers, to which colloidal particles are strongly attracted; this may lead to a change in the melting scenario. Changing the field rotation angle, one can obtain different colloidal structures. At small rotation angles, the system behaves like a two-dimensional system with a purely repulsive soft-disk potential, whereas at large angles it is similar to a generalized Lennard-Jones (LJ) system with an (nm)-potential. When the field rotates in the plane of the system, its phase diagram qualitatively resembles that of a classical model system with a LJ pair potential. The results of the computer simulation of a two-dimensional system with a LJ potential in the presence of Gauss pinning are discussed in the context of its influence on the phase diagram and melting scenario. It is shown that random pinning with a Gauss potential leads to an increase in the hexatic phase range; formation of dense clusters near pinning centers, which reduce the average effective density of the system; and a change in the melting scenario.","PeriodicalId":732,"journal":{"name":"Physics of Wave Phenomena","volume":"33 3","pages":"169 - 176"},"PeriodicalIF":1.1,"publicationDate":"2025-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145167768","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}

Such particles in biological objects inevitably interact with proteins, which obviously affects the functions and properties of the nanomaterial. The influence of external conditions on the interaction of nanoparticles with proteins in the aqueous phase has still remained little studied. In this paper we investigate the influence of temperature and pH of the medium on the interaction of lysozyme protein with gold nanoparticles in aqueous solutions. It is found that the temperature of the medium affects the size of aggregates of gold nanoparticles with protein at pH 7.5 of the aqueous solutions. It is found that lysozyme prevents protein aggregation at acidic pH values; with an increase in temperature, gold particles with a lysozyme protein crown retain their size. The results of this study gain a deeper insight into the processes of interaction between enzymes and gold nanoparticles with a change in the solvent properties.","PeriodicalId":732,"journal":{"name":"Physics of Wave Phenomena","volume":"33 3","pages":"192 - 206"},"PeriodicalIF":1.1,"publicationDate":"2025-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145167767","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}
