A variety of materials, including metals, ceramics, composites and polymers, are used for manufacturing bioimplants. These implants face a variety of biological settings with varying physical-chemical characteristics, and how they interact with bones and tissues is a difficult problem. The implant needs to meet a number of requirements, including high corrosion resistance, biocompatibility, appropriate mechanical qualities, osteointegration, recipient health, and surgical skill. Blood and other bodily fluid components, which include plasma, proteins, water, chlorine, amino acids and salt, provide a serious corrosion risk to the implants. As per the study of failed stainless implants found that stress corrosion cracking, pitting-induced fatigue fracture, and corrosion from crevice attack account for about 70% of type 316L SS implant failures. PEEK has high X-ray transparency, stable physical and chemical characteristics, and mechanical properties similar to human bones. Surface modification of biomedical implants are frequently undertaken to enhance surface texture, biocompatibility, wear resistance, and corrosion resistance. AgNPs with high antibacterial effectiveness are widely employed in implant surface modification to avoid implant-related infections.","PeriodicalId":671,"journal":{"name":"Journal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques","volume":"20 2","pages":"373 - 386"},"PeriodicalIF":0.4,"publicationDate":"2026-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148752247","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}

MWNTs were exposed to 100 keV He ions at a fluence of 1 × 1016 ions/cm2. Raman spectroscopy and scanning electron microscopy were used to analyze the microstructure, defect content, and morphology of pristine and irradiated MWNTs before and after irradiation. The electrical conductivity, Seebeck coefficient, and power factor were tested throughout a temperature range of 300‒450 K. Raman measurements performed after irradiation reveal that the disorder parameter defined by the ID/IG ratio diminishes. Ion irradiation resulted in a considerable improvement in electrical conductivity and Seebeck coefficient due to improved structure and charge carriers. Ion irradiation increased the thermoelectric power factor to 1.2 μW m‒1 K‒2 at 475 K, the highest recorded value. The findings indicate that irradiation might be utilized to modify the transport characteristics of MWNTs.","PeriodicalId":671,"journal":{"name":"Journal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques","volume":"20 2","pages":"502 - 508"},"PeriodicalIF":0.4,"publicationDate":"2026-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148752299","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}

Examples of effective collaboration with industrial research are presented for several SR centers, including NSLS-II (United States), ESRF-EBS (France), MAX IV (Sweden), PAL (Pohang, Korea), and AichiSR (Japan). In Russia, the revitalized TSRC “Zelenograd” may serve as an example of future partnerships between SR centers and industry. Its beam parameters are expected to be comparable to those of the relatively small AichiSR facility, where up to 60% of beam time is utilized by various companies.","PeriodicalId":671,"journal":{"name":"Journal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques","volume":"20 2","pages":"490 - 501"},"PeriodicalIF":0.4,"publicationDate":"2026-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148752360","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}

Here we consider the motion of particles with transverse energies ε ~ еU0 close to the energy of potential barriers separating planar potential channels. Such motion is characterized by the possibility to move from one channel to another, as well as by the band quantum structure of allowed values of transverse energy. It is demonstrated that characteristics of motion, as well as parameters of accompanying electromagnetic radiation, are changing with a gap when a particle changes transverse energy from under-barrier level ε < еU0 to over-barrier level ε > еU0. Namely, the direction of particle drift in crystal deviates from the direction of channels and the frequency of its oscillations doubles. Simultaneously, the amplitude of deviations from the average drift direction decreases multiple times. As the result, the frequency of electromagnetic radiation emitted by the particle doubles and its intensity decreases abruptly. With further growth of transverse energy, the amplitude of oscillations decreases further, the frequencies of radiation emitted by the particle increase, but its intensity decreases.","PeriodicalId":671,"journal":{"name":"Journal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques","volume":"20 2","pages":"469 - 472"},"PeriodicalIF":0.4,"publicationDate":"2026-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148752170","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}
