Nondecaying surface plasmon polaritons in linear chains of silver nanospheroids / I. L. Rasskazov, S. V. Karpov, V. A. Markel // Opt. Lett. - 2013. - Vol. 38, Is. 22. - P. 4743-4746, DOI 10.1364/OL.38.004743 . - ISSN 0146-9592
Аннотация: We consider propagation of surface plasmon polaritons in linear chains of equidistant metallic nanospheroids. We show that, for suitably chosen parameters, the propagation is free of spatial decay in spite of the full account of absorptive losses in the metal. В© 2013 Optical Society of America.

Аннотация: В данной работе был изучен процесс восстановления растворов Ag (I) цитратными комплексами Fe (II), который позволяет получать наночастицы серебра с высокой стабильностью и концентрацией более 60 г/л. В ходе работы было установлено влияние скорости введения, скорости перемешивания, концентрации реагентов, рН среды и некоторых постсинтетических операций на средний размер наночастиц. Показано, что снижение концентрации Ag (I) и повышение концентрации стабилизатора, доведение рН реакционной среды до 7 позволяют получать наиболее мелкие и однородные частицы. В результате были найдены оптимальные условия, которые дали возможность уменьшить размер частиц и вместе с тем снизить концентрацию реактивов на 33 %. По данным РФЭС, ПЭМ, DLS и ИК были получены наночастицы металлического серебра с размером 6.5±1.8 нм, стабилизированные продуктом частичного распада цитрат-иона.
The reaction of reduction solution of Ag (I) by Fe (II) citrate complex was studied herein. This allows you to receive silver nanoparticles with high stability with a concentration above 60 g/l. It was determined that the nanoparticles size depends on the injection rate, mixing rate, reagent concentration, pH and some post-synthetic operations on the average size of nanoparticles. It was shown that decreasing the concentration of Ag (I) and increasing the concentration of stabilizer also bringing pH to 7 lead to small and uniform particles. Optimal conditions were found that made it possible to reduce particle size and reduce the concentration of reagents by 33 % in the results. According to XPS, TEM, DLS and FTIR datas, nanoparticles of metallic silver with a size of 6.5±1.8 nm were obtained, which stabilized by the product of partial decay of the citrate ion.

Аннотация: We have studied light induced processes in nanocolloids and composite materials containing ordered and disordered aggregates of plasmonic nanoparticles accompanied by their strong heating. A universal comprehensive physical model that combines mechanical, electrodynamical, and thermal interactions at nanoscale has been developed as a tool for investigations. This model was used to gain deep insight on phenomena that take place in nanoparticle aggregates under high-intensity pulsed laser radiation resulting in the suppression of nanoparticle resonant properties. Verification of the model was carried out with single colloidal Au and Ag nanoparticles and their aggregates. © 2017 Optical Society of America.

Аннотация: The subsolidus phase equilibria in the system Ag2MoO4–Rb2MoO4–Sc2(MoO4)3 were studied and two new triple molybdates, Rb9Ag3Sc2(MoO4)9 and Rb7Ag5Sc2(MoO4)9, were found. The structures of Rb7Ag5Sc2(MoO4)9 and isostructural Rb7Ag5Sc2(WO4)9 of the Cs7Na5Yb2(MoO4)9 type (the space group R32) were determined. The found composition of the triple tungstate crystal, Rb7Ag4.61Sc2.13(WO4)9, indicates a non-stoichiometric compound formula, Rb7Ag5–3xSc2+x(WO4)9. Both structures have one incompletely occupied Ag site, and structure Rb7Ag4.61Sc2.13(WO4)9 also contains two positions with mixed Ag and Sc. Both compounds contain ‘lanterns’ [M2(XO4)9] (M = (Sc, Ag), Sc; X = Mo, W), which are strengthened by three AgO2 dumbbells to give isolated building blocks [Ag3M2(XO4)9] forming two-story hexagonal layers resembling the structure of glaserite K3Na(SO4)2. Similar layers of [Ag3Sc2(WO4)9]9− building blocks were also found by us in the structure of Rb9–xAg3+xSc2(WO4)9, which is close to that of Rb9Ag3Sc2(MoO4)9. Similar layers of the [M2(TO4)9] units were also observed in Cs7Na5Yb2(MoO4)9 and Na13Sr2Ta2(PO4)9. The title compounds belong to the series of rhombohedral triple molybdates and tungstates with a ≈ 9–10 Å and large c-periods (more than 20 Å), which have layered or open 3D framework structures. Like many compounds of this series, Rb7Ag5Sc2(XO4)9 (Х = W, Mo) at elevated temperatures have significant ionic conductivity reaching values 6.1·10−3 S cm−1 at 703 K (X = Mo) and 1.4·10−3 S cm−1 at 733 K (X = W) with Еа = 0.7 eV and 0.6 eV, respectively.

Synthesis and synergistic effect of antibacterial composites based on concentrated hydrosols of silver nanoparticles combined with cephalosporins antibiotics / S. A. Vorobyev, G. V. Novikova, A. V. Demina [et al.] // Inorg. Chem.

Silver nanoparticles -- Concentrated hydrosols -- Cephalosporin antibiotics -- Antibacterial activity -- Minimal inhibitory concentration
Аннотация: Silver nanoparticles may be used as potential antimicrobial agents. Concentrated silver nanoparticles (AgNPs) were synthesised by the Carey Lee method. Then, antibiotics, such as disodium ceftriaxone, sodium cefotaxime, sodium cefazolin and sodium cefoperazone, were added to the AgNPs at the ratio of AgNPs:antibiotic = 5:1. The concentrated hydrosols were examined using UV–Vis, FTIR-spectroscopy, dynamic light scattering and transmission electron microscopy. The spectra plasmon resonance of silver nanoparticles and their combination with antibiotics had a single strong peak at 412–415 nm. The transmission electron microscopy micrographs showed different forms. The average size of AgNPs-antibiotic particles was smaller than that of AgNPs. The antibacterial activities of AgNPs, antibiotics and AgNPs-antibiotics were determined by the disk diffusion method against Staphylococcus aureus and Escherichia coli. The most significant enhancement of the antibacterial effect over the antibiotic was demonstrated by AgNPs-disodium ceftriaxone against E.coli. Also, the minimal inhibitory concentration (MIC) of the AgNPs-antibiotics was defined. All the AgNPs-antibiotic exhibited a synergistic enhancement by AgNPs and the antibiotic of antibacterial activity. A possible explanation of this phenomenon was proposed. Our results suggest that the synthesis of the concentrated hydrosol of the AgNPs-antibiotics is essential for studying similar nanosystems.

Кл.слова (ненормированные):
silver nanoparticles (NPs) -- concentrated silver organosols -- phase transfer of nanoparticles -- X-ray photoelectron spectroscopy (XPS) -- transmission electron microscopy (TEM) -- conductive silver films
Аннотация: Due to their unique properties, organosols of silver nanoparticles are widely used in optical and semiconductor devices, to produce electrically and thermally conductive films, as catalysts, antibacterial materials, etc. This work proposes a simple and highly productive method for the preparation of silver organosols, which have a metal concentration as high as 1800 g/L and contain spherical nanoparticles with low polydispersity and a median size of 9.1 nm. The method consists in the initial preparation of silver nanoparticle hydrosols with a concentration of higher than 30 g/L followed by the transfer of the NPs into an organic phase of o-xylene. A set of physical research methods has been employed to study the regularities of the extraction of silver nanoparticles with o-xylene in the presence of cetyltrimethylammonium bromide (CTAB) and ethanol and to determine the optimal process conditions, under which the extraction degree is as high as 62.5%. It has been found that bromine anions contained in CTAB molecules cause the aggregation of some amount of silver nanoparticles with the formation of silver metal sediment in the aqueous phase. According to X-ray photoelectron spectroscopy data, the sediment contains bromide ions (up to 4 at %) on the particle surface. Organosols synthesized under optimal conditions are stable for more than 7 months and withstand repeated cycles of drying and redispersing. Silver organosols have been used to obtain metal films with an electrical conductivity of about 68 500 S/cm, which increases to 412 000 and 509 500 S/cm (87.8% of the electrical conductivity of bulk silver) after thermal treatment at 150 and 250°C, respectively.

Аннотация: We have shown significant suppression of resonant properties of metallic nanoparticles at the surface plasmon frequency during the phase transition “solid–liquid” in the basic materials of nanoplasmonics (Ag, Au). Using experimental values of the optical constants of liquid and solid metals, we have calculated nanoparticle plasmonic absorption spectra. The effect was demonstrated for single particles, dimers and trimers, as well as for the large multiparticle colloidal aggregates. Experimental verification was performed for single Au nanoparticles heated to the melting temperature and above up to full suppression of the surface plasmon resonance. It is emphasized that this effect may underlie the nonlinear optical response of composite materials containing plasmonic nanoparticles and their aggregates. © 2017, Springer-Verlag Berlin Heidelberg.

Аннотация: We present an experimental spectroscopic study of large random colloidal aggregates of silver nanoparticles undergoing local restructuring. We argue that such well-known phenomena as strong fluctuation of local electromagnetic fields, appearance of "hot spots" and enhancement of nonlinear optical responses depend on the local structure on the scales of several nanosphere diameters, rather than the large-scale fractal geometry of the sample.

Аннотация: Carey Lea silver hydrosol is a rare example of very concentrated colloidal solutions produced with citrate as only protective ligands, and prospective for a wide range of applications, whose properties have been insufficiently studied up to now. Herein, the reactivity of the immobilized silver nanoparticles toward oxidation, sulfidation, and sintering upon their interaction with hydrogen peroxide, sulfide ions, and chlorocomplexes of Au(III), Pd(II), and Pt(IV) was investigated using SEM and X-ray photoelectron spectroscopy (XPS). The reactions decreased the number of carboxylic groups of the citrate-derived capping and promoted coalescence of 7 nm Ag NPs into about 40 nm ones, excluding the interaction with hydrogen peroxide. The increased nanoparticles form loose submicrometer aggregates in the case of sulfide treatment, raspberry-like micrometer porous particles in the media containing Pd(II) chloride, and densely sintered particles in the reaction with inert H2PtCl6 complexes, probably via the formation of surface Ag-Pt alloys. The exposure of Ag NPs to HAuCl4 solution produced compact Ag films along with nanocrystals of Au metal and minor Ag and AgCl. The results are promising for chemical ambient temperature sintering and rendering silver-based nanomaterials, for example, for flexible electronics, catalysis, and other applications.

Аннотация: Optical nonlinearities in aggregates of nanoparticles formed in silver hydrosols (SHs) are studied under pico- and nanosecond pulsed laser excitation. The dependence of the nonlinear refractive index n (2) on the degree of hydrosol aggregation is studied experimentally at the wavelength lambda=1.064 mu m. It is found that n (2) changes sign when the degree of hydrosol aggregation is increased. Various physical effects occurring in resonant domains of the aggregates are analyzed using a simple physical model of two bound silver nanoparticles. The theory takes into account thermal, elastic, electrostatic, and light-induced effects. Experimental results are discussed in the context of this theory.

Аннотация: A new method of preparation of bulk textured Bi2223 ceramics and Bi2223 + Ag composites, based on room temperature pressing of foamed precursor (Bi2223, Bi2223 + Ag) in a liquid medium, is proposed. SEM and XRD data prove a high degree of texture of the bulk samples obtained. Magnetic measurements performed in directions H parallel to c-axis and H parallel to a-b-planes of Bi2223 crystallites demonstrates anisotropy of magnetization confirming the texture of the ceramics. The materials obtained possess large diamagnetic response in the direction H parallel to a-b-planes of Bi2223 crystallites at both 77.4 and 4.2 K.

Аннотация: The model of a polarization-preserving anisotropic mirror is proposed. The mirror is a plane boundary of a metal–dielectric nanocomposite that consists of silver spheroidal nanoparticles dispersed in a transparent matrix. The dependence of reflection spectra on the shape of the nanoparticles is studied. It is shown that in one region of the spectrum, the mirror preserves the sign of polarization in the reflected light. © 2017, Allerton Press, Inc.

Аннотация: The present study reports synthesis of silver nano-antibiotics from aqueous extract of H. dissectum. The nano-antibiotics were characterized using UV–visible spectra which displayed maximum absorbance at 430 nm. The role of phytocomponents as reducing agent and stabilization of silver nano-antibiotics was depicted with Fourier-transform infrared spectroscopy which revealed presence of hydroxyl and carboxyl groups associated with silver nano-antibiotics. The crystalline nature was studied with X-ray diffraction which showed Bragg’s intensities at 2θ angle which denoted (101), (111), (200), (220), (311) planes. The morphological characteristics were studied using Transmission Electron Microscopy to reveal the size ranging from 5 to 50 nm. The bactericidal activity of nano-antibiotics was studied via well diffusion and minimal inhibitory concentration assay against members of drug-resistant communities bearing resistant to more than ten standard antibiotics. Nano-antibiotics displayed highest activity against Ps. aeruginosa strain 55 and Methicillin-resistant Staphylococcus aureus with 16 mm zone of inhibition followed by Kl. pneumoniae strain 104 and E. coli strain 55. Moderate activity was observed against Ac. baumannii strains with 12 mm zone of inhibition. The obtained results envision the role of plant mediated nano-antibiotics as one of the best suited alternatives towards combating drug resistant pathogens.
