ELECTROSPRAYING CONDUCTIVE SOLUTIONS IN NORMAL CONDITIONS WITH A WIDE VOLUME FLOW VELOCITY RANGE

"Nauchnoe priborostroenie", 2017, vol. 27, no. 2, pp. 3—12.
doi: 10.18358/np-27-2-i312
 

The production of charged particles (ions, clusters) from fluid in a strong electric field while in normal conditions was experimentally studied using a dynamic liquid flow splitter on the meniscus. The existence of non-droplets regimes for obtaining charged particles for liquid flow rates up to 1000 μl/min, solute concentrations up to 1 M and acid content in solution up to 1 % was displayed. Depending on the experimental conditions the existence of a "classic" fluid electrospraying regime in normal conditions in air and a non-droplets regime were demonstrated for obtaining charged particles current. The performance of an ion mobility spectrometer with Bradbury–Nielsen gate is demonstrated in a non-droplets regime of obtaining charged particles using the example of the suspension of human cells epidermoid carcinoma A431. The cells concentration in the suspension is 1 ppm.

ALTERNATIVE SOLUTIONS OF MASTER MOLDS CREATION FOR FABRICATION MICROFLUIDIC CHIPS BY "SOFT" LITHOGRAPHY

"Nauchnoe Priborostroenie", 2017, vol. 27, no. 2, pp. 13—20.
doi: 10.18358/np-27-2-i1320
 

Special attention is paid to improving the methods of fabrication microfluidic devices in the research laboratories. The search of solutions for more efficient and cheaper ways of manufacturing master molds for "soft" lithography (in comparison with the traditional method of photolithography), which do not require expensive equipment and clean room conditions is carried out. The fabrication of elastic master molds using "soft" lithography is a fairly convenient technology at a presence of master mold from silicon and photoresist, since in this case only additional materials are required. An important advantage of this approach is the possibility of fabrication solid replicas of adhesive compounds and epoxy resins. The time for manufacturing master molds from epoxy compounds (for elastomer replicas) can increase significantly, in other cases, the duration of the process is ~4.5—9 hours. Laser microprocessing of metals are relatively cheap and operational. These technologies allow to produce a solid master mold for a short time for "soft" lithography, which increases the maximum possible number of fabricated polymer replicas.

THE ELECTROKINETIC POTENTIAL MEASUREMENTS OF BIOCOLLOIDS PARTICLES

"Nauchnoe Priborostroenie", 2017, vol. 27, no. 2, pp. 21—31.
doi: 10.18358/np-27-2-i2131
 

There the ways of measurements of an electrokinetic potential (zeta-potential) of colloid particles and, in particular, a problem assotiated with use of the classical electrophoresis are briefly discussed in the article. The methods and devices based on measurements of a light scattering of particles and became a frequent practice now are analyzed most extensively. It is shown that the Doppler spectroscopy of the light scattered by particles is accompanied by difficulties not only by the analyse of particle sizes, in particular, for polydisperse colloids, but also, first of all, while measuring the zeta-potential because it is defined not so much by the size, as totality of peripheral parameters of the particles. The way of measurement near to a classical electrophoresis is offered, where the sign-variable electric field is used, the drift length of the particles and a difference of electric potentials are minimized.

In the present article the methods of holographic interferometry, which are highly informative and high-precision tool for obtaining data are presented. The relevance and urgency of application of the shearing interferometer for measurement of the disturbed object are revealed. The analysis of the effect of cross-interference on the measurement accuracy, namely: mismatch, not exceeding 2 µm, the measurement error in the mode of determining the relative magnitude of the displacement vector does not exceed 0.015 rad, accounting for 0.002 shares of interference fringes, and with the additional offset of ~10 µm, the maximum error does not exceed 0.001 of a share of the interference fringes are performed. Equalization interference for the shearing interferometer, where it is seen that for the case of rotation of the plate relative to the axis Õ2 the graph of the phase difference and the derivative of the angle αó is essentially nonlinear, which leads to the deformation of interference field and the error of the read information are received. The first investigated the limits of applicability of the interferometer and the upper limit of the measuring range of the magnitude of the displacement vector is equal to 1.5 mm and the lower limit determined by displacement of 0.01 µm.

OBSERVATION OF THE IMPACT OF THE SURFACE MAGNETIC CHARGES ON THE MAGNETIC INDUCTION INSIDE AND OUTSIDE A SIMPLE OF THE MAGNETIC FLUID, PLASED IN AN EXTERNAL MAGNETIC FIELD

"Nauchnoe Priborostroenie", 2017, vol. 27, no. 2, pp. 57—60.
doi: 10.18358/np-27-2-i5760
 

An NMR method was used to measure the magnetic induction B1 inside and both B2 and B3 outside a simple of magnetic fluid, placed in an external magnetic field with induction B0. The measurements showed that there was a magnetic induction inside the simple: B1 = B0 + (λ – K)µ0M, where M – magnetization, λ – the constant of effective field, K – demagnetization factor, outside the simple near the surface of normal B0: B2 = B0 + (λ + K)µ0M, near the surface of parallel B0: B3 = B0 – Kµ0M. Thus, when the surface of magnetic passes the normal B0 inside the simple, induction reduces on 2Kµ0M, and while passing outside, the induction increases on 2Kµ0M, this discrepancy to the Gauss theorem may by explained by the presence of the surface magnetic charges. The induction decreases on λµ0M at the exit through the side surface of the simple, and it increases on λµ0M at the entrance of it. It may be explained by the effect of the nanoparticles magnetic flow orientation.

THE STUDY OF THE INFRARED SPECTRUM OF A MAGNETIC NANOPARTICLES IN A MAGNETIC FIELD STRUCTURE

"Nauchnoe Priborostroenie", 2017, vol. 27, no. 2, pp. 61—65.
doi: 10.18358/np-27-2-i6165
 

The action of a magnetic field on the magnetite nanoparticles colloidal solution leads to the appearance of an oscillatory rotational absorbtion specrum of infrared radiation with an energy of lower vibration levels close to exchange interaction energy in the domains of the nanoparticles. The effect can be explained by the conversion of photons energy into the energy of vibrations, which break off the domain structure of magnetite above the Curies temperature. The depth of the potential well, defined by bringing together the vibration levels, is more than Curies temperature in energetic units. That's why it is possible to suppose tunnel effect or a vibration and rotational levels superposition as a reason of the domain destruction.

A number of examples, both trivial and complex enough, to demonstrate the effectiveness of variational methods for mathematical modeling of various physical processes. Some of the examples may be modeled using alternative approaches, such as the acoustic model of porous media (Bio theory), probably only modeled using variational techniques. The focus of the review is made on the details cast of the application of variational approach, which is not always done in the original papers in which these methods are used to solve complex problems. In the appendix provides some useful information on variational methods, including the Onsager principle of symmetry of kinetic coefficients and generalized variational principle.

Basis of operation of a deconvolution of a spectrum is filtering according to Winer. Multiplication of an exit of the filter of Winer by an input spectrum is made for suppression of fluctuations of Gibbs and low-frequency noise. The threshold curve determining operation of detection of peaks contains the background component dividing a useful signal and noise, and the local component separating noise satellite peaks. 2-fold differentiation of result of threshold processing is made for additional increase in resolution of detection of peaks.

THE BINARY ALGORITHM FOR THE ANALYSIS OF THE SPECTRUM AMPLITUDE AND RECOVER OF HARMONIC COMPONENTS SIGNALS IN THE PRESENCE OF UNCORRELATED BACKGROUND NOISE

"Nauchnoe Priborostroenie", 2017, vol. 27, no. 2, pp. 83—90.

The problem of detecting and distinguishing between the informative components of multicomponent signals in the presence of additive uncorrelated noises. The solution of this problem is based on harmonic analysis Fourier series using the sign-function analog-stochastic quantization of the investigated signal. This kind of quantization makes it possible to carry out extremely coarse two-level quantization without a systematic error, regardless of the statistical properties of the analyzed signals. A developed algorithm for harmonic analysis provides a high computational efficiency. The practical implementation of these algorithms basically reduces to performing the simplest arithmetic operations of summation and subtraction of the discrete values of the filtering functions calculated at the instants of time when the result of sign-function analog-stochastic quantization changes its sign. For the decision about the detection of harmonic components, we use a criterion for exceeding of a threshold value by estimating the amplitudes of the harmonic components. The results of experimental studies show that the use of sign-function analog-stochastic quantization has allowed to effectively eliminate the effect of the additive uncorrelated noise and to obtain high quality recover of continuous multicomponent signals useful.
