The disintegration factor affecting the bacteria in the knitted fabric is the UV-C radiation in the range of 265–270 nm distributed via woven optical fibres. The way of integrating elements of the system generating the UV-C radiation in the structure of the spacer knitted fabric was designed, as well as various configurations of optical fibres arrangement, fibre density, number of radiation sources, and diode types were tested. The material was contaminated with selected microorganisms indicative of sanitary contamination and important in terms of nosocomial infections. The scope of the research included microbiological (quantitative and qualitative) analyses of selected taxonomic groups of microorganisms (mesophilic bacteria, fungi, actinomycetes) before and after the irradiation process. The analysis of the research results and the applied modification of the knitted fabric turned out to be effective in reducing the amount of potentially pathogenic microorganisms.","PeriodicalId":54670,"journal":{"name":"Opto-Electronics Review","volume":"50 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74460548","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The presentation is based on deep intrinsic relations between the singularities and the rotational phenomena in light; it involves essentially the dynamical aspects of light fields and their interactions with matter. Due to their topological nature, the singularities of each separate parameter (phase, polarization, energy flow, etc.) form coherent interrelated systems (singular networks), and the meaningful interconnections between the different singular networks are analysed. The main features of singular-light structures are introduced via generic examples of the optical vortex and circular vortex beams. The review describes approaches for generation and diagnostics of different singular networks and underlines the role of singularities in formation of optical field structures. The mechanical action of structured light fields on material objects is discussed on the base of the spin-orbital (canonical) decomposition of electromagnetic momentum, expressing the special roles of the spin (polarization) and spatial degrees of freedom. Experimental demonstrations spectacularly characterize the topological nature and the immanent rotational features of the light-field singularities. The review is based on the results obtained by its authors with a special attention to relevant works of other researchers.","PeriodicalId":54670,"journal":{"name":"Opto-Electronics Review","volume":"98 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81228111","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we have studied the impact of alloying on CsSnBr3 perovskite nanoparticles with reduced graphene oxide (rGO) on its structural and optical properties for its utility in solar cell devices. The formation of phase and highly crystalline behavior of the pristine CsSnBr3 and rGO alloyed CsSnBr3 has been observed by the X-ray diffraction (XRD) technique. A direct bandgap of 1.81 eV and 1.75 eV has been calculated from the Tauc plot for CsSnBr3 and rGO alloyed CsSnBr3 respectively indicating a decrease in band gap due to rGO alloying. The photoluminescence (PL) plot represents a blue shift phenomenon in the PL peak of CsSbBr3 after rGO alloying. Also, a decrease in full-width half maxima (FWHM) has been seen after alloying CsSnBr3 with rGO which further indicates an increase in crystalline size and a decrease in grain boundaries. Furthermore, the surface morphology of rGO alloyed CsSnBr3 has been noticed from scanning electron microscopy (SEM) images depicting a nano rod-like structure uniformly spread over the rGO sheet. This study suggests structural and optical tuning along with enhancement in properties of CsSnBr3 after rGO alloying for its utility in the fabrication of high-performance and ultra-stable solar cell devices.","PeriodicalId":54670,"journal":{"name":"Opto-Electronics Review","volume":"25 1","pages":"124160B - 124160B-8"},"PeriodicalIF":1.6,"publicationDate":"2023-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79118983","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
