Journal of Physics: Conference Series 2020年第1期1461卷

作者： A A Sergeev K A Sergeeva A A Leonov S S Voznesenskiy Institute of Automation and Control Processes FEB RAS 5 Radio Street Vladivostok 690041 Russia

The interaction of optical radiation with dielectric microparticles, leading to the emergence of field spatial localization called the 'photonic nanojet' was numerically and experimentally studied within the wide range of environment refractive indexes. It is established that at a certain ratio of the microparticle and the environment refractive indexes, as well as the curvature of the particle profile, the photonic nanojet effect can be used to locally excite the sensitive layer of fluorescent sensors of chemical compounds in liquid and gaseous media.

With the introduction of new rules for calculating the general needs of a residential building in 2017, the transition to full payment for all energy resources consumed by residents of apartment buildings on single meters has caused many questions related to the reliability of the calculation. It is common knowledge that in the absence of automated accounting systems in multi-apartment buildings and incomplete equipping of apartments with individual meters, situations often arise when the total amount of public utilities is much higher than the total consumption of apartments in the house. The reasons for this excessive imbalance may be different. The most probable of these are leakages in pipelines, illegal connections to heat networks, inconsistency of normative values to actual consumption. Proceeding from practical material, in this report we will consider one of the most important factors affecting the indicators of the general needs of an apartment house - an indirect method of measuring the total consumption of hot water in residential building. The report proposes a method for increasing the accuracy of indirect measurements used for the commercial recording of hot water consumption. The method is based on the determination of the correction to the results of measuring the difference in flow, which makes it possible to estimate the influence of the errors of flowmeters and take this factor into account in the further calibration of the flowmeters. Consideration is made on the example of accounting for the consumption of hot water in a particular residential building. © 2018 IEEE.

China

The problem of evaluating soft sensors for plants with irregular output measurement time is considered. In order to find the relationship between inputs and output, the wavelet-transformed inputs are integrated into the regression model framework. A suitable procedure for wavelet type selection is discussed. An example is provided to illustrate successful application of the proposed approach and an industrial case study is given for soft sensor evaluation of a reactive distillation process.

The search for inexpensive and efficient methods of forming thin BaSi2 films as a promising material for photovoltaic is an actual task. The co-deposition of Ba and Si atoms with alloy thickness of 100-120 nm on the silicon substrate at room temperature with following annealing (SPE method) was proposed. Ba-Si alloy compounds then were thermally annealed at different temperatures and three samples were formed: #1 at T = 600 ° C, #2 at T = 700 ° C and #3 at T = 800 ° C. Polycrystalline films with an orthorhombic BaSi2 structure were formed by XRD, UV-VIS, FIR and Raman spectroscopies data. BaSi2 grains in samples #1 and #2 have sizes 62-64 nm and 86 nm in the sample #3 from XRD data calculations by Scherrer formula. Proposed growth method resulted to strong compression of the BaSi2 unit cell volume on 1.78 - 2.70%. The strongest compression was observed after annealing at 800oC, which was accompanied by desorption of a noticeable amount of barium and a strong decrease in the film thickness in the sample #3. The formation of nanosize Si clusters was confirmed by Raman data for samples #2 and #3, but they did not observed in the sample #3. So, the film, formed at 800oC, is the most qualitative in terms of structure and single-phase BaSi2, but with strong decrease of initial Ba-Si alloy thickness due to Ba desorption. © 2018 Trans Tech Publications, Switzerland

An algorithm for reconstruction particle size distribution function and refractive index is proposed. The algorithm uses agglomerated debris particle model as most convenient to represent particles shape of dust and urban aerosols for calculation polarization properties. Algorithm involve three model functions of particles size distribution: power law, single-mode lognormal, two-mode lognormal, which are parametrized by one, two and five coecients correspondingly in case of polarization measurements. © 2018 SPIE.

Hybrid nanomaterials with chemical composition integrating light-emitting low-loss semiconductors with plasmon-active metals are highly demanded for optoelectronics, nanophotonics and sensors. However, there is a still lack for high-performing and inexpensive methods allowing facile integration of plasmonic and all-dielectric concepts within unified practically relevant nanostructures and ensuring their production at gram-per-hour yield. Here, we report one-step synthesis of hybrid [email protected] nanomaterial with unique composition and morphology via scalable and high-performing pulsed laser irradiation of isopropanol solution containing commercial Si micro-powder and AuCl 4- ions. The resulting hybrid nanomaterial represents sub-micron nanocrystalline Si grains embedded into Au surrounding forming micro-spheres (MSs) additionally decorated with Au nanoparticles. Such unique structure and chemical composition of the [email protected] MSs permits to efficiently absorb and enhance incident radiation within rather broad spectral range spanning from visible to near-IR making the nanomaterial promising for plasmon-mediated amplification of linear and nonlinear optical effects. Efficient generation of broadband hot-carrier-induced photoluminescence of nanocrystalline Si grains upon IR femtosecond-laser sub-nJ pump proves the produced nanomaterial as advanced nanophotonic platform for nano-spectroscopy and sensing.

Femtosecond laser nanostructuring of metal surfaces is a powerful tool for improvement of their various properties. Namely, increase of optical absorption ("black metals"), superhydrophobity, surface hardening, as well as improvement of tribological properties have been reported previously. Here we show the improvement of bond slip of nanostructured reinforcement bars with concrete. We demonstrate strong dependence of straining force and pulling force on the regime of surface nanostructuring. In particular, two-fold increase of straining force and pulling force can be achieved at the highest fluence in the regime of "black metal". Our finding has high practical importance for advanced civil engineering. © 2018 institute of Physics *** right reserved.

A simple aqueous based synthesis technique at room temperature was performed for manganese-doped zinc sulfide quantum dot preparation. Under 4 eV excitation quantum dots show photoluminescence bands at 2.1 and 3.1 eV corresponded to Mn2+ and intrinsic ZnS emission respectively. ZnS quantum dots were used as the luminescent sensing element for methane detection in aqueous media. The luminescent sensor response occurs due to photoinduced electron transfer from QDs to methane molecule resulting in QD luminescence quenching. © 2018 Trans Tech Publications, Switzerland

Magnesium can be used as a new biodegradable material for orthopaedic applications due to its outstanding properties including high biocompatibility, proper mechanical stiffness and biodegradability. Direct laser deposition (DLD) as a way of biomedical implant production has been used to make bulk pure Mg. Surface morphology, microstructure and mechanical properties of DLD sample have been studied. The relative porosity of DLD Mg sample has been determined. © 2018 institute of Physics *** Rights Reserved.
