In this work, we show that the strong coupling at the nanoscale can lead to vacuum induced transparency. As an example, we study the case where a three-level quantum system is placed near a MoS 2 nanodisk. We ﬁnd that we may obtain either single or multiple vacuum induced transparency effects, depending on the distance between the quantum system and the MoS 2 nanodisk and the resonance energy of the quantum system. strong-light matter coupling with nearby quantum systems. Here, we showed that this strong coupling at the nanoscale can lead to vacuum induced transparency when a three-level quantum system is placed near a MoS 2 nanodisk and also has resonance energy close to an exciton-polariton resonance of the MoS 2 nanodisk. We found that depending on the distance of the quantum system from the MoS 2 nanodisk and the resonance energy of the quantum system, we may obtain either single or multiple vacuum induced transparency effects.","PeriodicalId":336049,"journal":{"name":"The 3rd International Online-Conference on Nanomaterials","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125246492","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}

Polythiophene is a prominent exam-ple of conducting polymers and convinces with excellent conductivity and stability—and is yet barely used for the construction of biosensors. We want to address the fundamental lack of straightforward fabrication procedures for bioreceptor immobilization platforms based on polythiophene. We investigate the literature-known monomer 3-thiopheneacetic acid and present our newly developed method for electrochemical coupling of the linker p-aminobenzoic acid to deposited polythiophene films. Aminated bioreceptors can subsequently be immobilized via EDC/NHS click chemistry. Films were electropolymerized and modified by chronopotentiometry, characterized by electrochemical impedance spectroscopy, surface-enhanced Raman spectroscopy, as well as energy-dis-persive X-ray spectroscopy. Both of the presented methods allow for the fabrication of functionalized polythiophene thin films of high conductivity and good reproducibility, while convincing with their ease in synthesis.","PeriodicalId":336049,"journal":{"name":"The 3rd International Online-Conference on Nanomaterials","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133917236","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}

Therefore, the aim of this work is (1) characterize Fc by Fourier-transform infrared spectroscopy (FTIR) and scanning electron microscope (SEM), (2) optimize heterogeneous photo-Fenton in WW treatment, (3) study the kinetic rate and regeneration of Fc. The FTIR analysis confirms the presence of Fe 2+ in its composition and SEM images showed that Fc is a porous compound. Under the best operational conditions, as follows: [Fc] = 0.50 g/L, [H 2 O 2 ] = 194 mM, pH = 3.0, agitation = 350 rpm, T = 298 K, radiation UV-C, t = 240 min, it was achieved a significant TOC removal (82.7%). The results showed that the Fc catalyst decreased its stability along 3 consecutive cycling processes with the TOC removals decreasing from 82.7 to 76.2 and 63.9% from the 1st, 2nd and 3rd cycle. Fermi’s non-linear kinetic model was applied, and it was observed a k TOC = 4.77 × 10 −2 min −1 . In conclusion, ferrocene is a suitable compound to perform the treatment of a WW by heterogeneous photo-Fenton process.","PeriodicalId":336049,"journal":{"name":"The 3rd International Online-Conference on Nanomaterials","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115581691","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}

A phenomenon that has been studied is the modification of the resonance fluorescence spectrum of the quantum dot by the presence of the plasmonic nanostructure. The most common plasmonic nanostructure that has been studied is the metallic (mainly gold or silver) nanosphere and in most studies the quantum dot is modeled as a two-level quantum system. In this work, we model the quantum dot structure with a three-level V-type quantum system, which can naturally arise in quantum dots, and study the resonance fluorescence spectrum near a metallic nanosphere. We show that the present system leads to quantum interference effects due to the presence of the metallic nanoparticle and specifically due to the anisotropic Purcell effect that occurs in the photon emission of the quantum dot near the metallic nanosphere. We then study the resonance fluorescence spectrum, for different distances between the quantum dot and the metallic nanosphere and show that the resonance fluorescence spectrum changes significantly from a single-peak spectrum to a multipeak spectrum. The effects of quantum interference in the resonance fluorescence spectrum are also explored.","PeriodicalId":336049,"journal":{"name":"The 3rd International Online-Conference on Nanomaterials","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126715722","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}
