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: Experimental data have been presented on the influence of silver on the viscosity and thermal conductivity of a dispersion of diamond nanoparticles. A stable dispersion (5 wt %) of detonation nanodiamond particles has been used in the experiments. Silver ions have been introduced electrolytically into the dispersion of diamond nanoparticles. Silver concentration was not higher than 0.05 wt %. It has been shown that the introduction of silver ions significantly affects the thermal conductivity and viscosity of the dispersion.

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.
