The Density Functional Theory (DFT) computations of the electronic structures of undoped, B- and N-doped graphene sheets with adsorbed chromate anions $mathrm{CrO}_{4} ^{2-}$ were performed within molecular cluster approach. Relaxed geometries and binding energieswere calculated using B3LYP hybrid exchange-correlation functional. Oscillator strengths of electronic transitions of $mathrm{CrO}_{4} ^{2-}$ anions adsorbed on graphene surface were calculated by TD-DFT method. The optical absorption spectra of aqueous solutions containing mixes of carbon nanotubes and chromate anions were measured. The luminescence emission spectra of carbon nanostructures with adsorbed chromate anions deposited on silicon glass substrate were measured. Two stable configurations were found for adsorption of $mathrm{CrO}_{4} ^{2-}$ anions on undoped graphene sheets. The calculated energy of the lowest-energy transition of the adsorbed $mathrm{CrO}_{4} ^{2-}$ anion is reduced by 0.5 eV in comparison with corresponding transition energy of free anion. Spectra of optical absorbance and luminescence of the systems containing carbon nanostructures measured before and after adsorption of chromate anions reveal substantial difference that confirms the principal possibility of monitoring the $mathrm{CrO}_{4} ^{2-}$ anion adsorption on carbon nanostructures.","PeriodicalId":239169,"journal":{"name":"2018 IEEE 8th International Conference Nanomaterials: Application & Properties (NAP)","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134474240","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}

We consider liquid crystals immersed into a nano-structured sponge-like polymer network. The network's long chains impose a desired alignment for liquid crystal molecules enabling the creation of thick homogeneous liquid crystal slabs (up to 1 mm, in comparison with available today only 50 microns thick aligned liquid crystal layers). The properties of these materials are enriched tremendously by adding various nanoparticles. Mixing ferroelectric nanoparticles with a liquid crystal, generates ultrahigh electric fields within the liquid crystal, which, combined with their small size, produces a uniquely exciting and largely unexplored system of composite materials which exhibit novel collective particle-host interactions. These interactions promise a variety of exotic electro-optic and other applications. In this case, ferroelectric nanoparticles share their high intrinsic sensitivity to electric fields with the entire liquid crystal matrix. Therefore, doping the liquid crystal with ferroelectric nanoparticles brings benefits of a lower driving voltage and faster switching speed than in any liquid crystal devices available today. As a result, we demonstrate the power of nanotechnology to amplify by orders of magnitude the natural properties of liquid crystals by doping them with nanoparticles and hosting them in a nano-confining polymer matrix.","PeriodicalId":239169,"journal":{"name":"2018 IEEE 8th International Conference Nanomaterials: Application & Properties (NAP)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121075073","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}

Achieving the stability of nanoparticle solutions over time is one of the important tasks for researchers as well. Preparation of new antimicrobial release systems based on Ag NP and biological polymers will contribute to create effective antimicrobial agents. In current paper we evaluate antibacterial activity of chitosan-Ag NPs treated by ultrasound against Gram-positive and Gram-negative microorganisms. Ag NPs were synthesized via polyol method. 2% chitosan solution used to produce polymer-Ag NPs composite. X-ray diffraction (XRD) technique, scanning electron microscopy (SEM), and UV-Vis spectroscopy were used for NPs characterization. The antimicrobial activity of the Ag NPs and Ag NP/chitosan solution was tested against S. aureus, S. pyogenes, E. coli,. K. pneumonia, P. aeruginosa, P. vulgaris and Candida spp. Pure Ag NPs demonstrate high antimicrobial activity against all microorganisms. The ultrasonic treatment of nanoparticles makes them more active in relation to gram-negative bacteria but sonicated composition of the Ag NPs and 2 % chitosan gel express the highest antimicrobial activity against all types of microorganisms.","PeriodicalId":239169,"journal":{"name":"2018 IEEE 8th International Conference Nanomaterials: Application & Properties (NAP)","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116343214","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}
