Typically, polymer composites and ceramics are used to create biosensors. Materials with properties that ideal for biosensors chemical sensors include AgNO3 (silver nitrate), PVDF (polyvinylidene fluoride), HA (hydroxyapatite). Polyvinylidene fluoride (PVDF) has been widely in several applications because of its well-known superior ferroelectric characteristics biocompatibility. The brittleness low bending strength hydroxyapatite limit applicability. Several composite formulations have...
The article presents an innovative approach to the analysis of nanofluids using a nonlinear multifractal algorithm. conducted research concerned prepared from SiO2 nanoparticles (~ 0.01 g) suspended in 100 ml demineralized water and 99.5% isopropanol. Subsequently, were subjected conventional characterization methods such as: determination contact angle, zeta potential, pH, particle size analysis. obtained results show that nanofluid is stable terms agglomeration over time (nanofluid...
Liquid penetration into the glass nozzle with inner diameter of 1 mm during bubble, departures in distilled (surface tension = 65 mN/m) and not 72 mN/m), water was investigated. It has been shown that dynamics liquid movement inside depend on surface tension. Maximum value is different for water. In depth depends air volume flow rate. For desilted this constant.
The identification of the shape bubble trajectory is crucial for understanding mechanism motion in liquid. In paper it has been presented technique 3D reconstruction using a single high speed camera and system mirrors. experiment glass tank filled with distilled water was used. nozzle through which bubbles were generated placed centre tank. movement recorded camera, Phantom v1610 at 600 fps. techniques image analysis applied to determine coordinates mass each image. can be obtained by...
The study examines problems of heat conduction in a half-space with thermal conductivity coefficient that is dependent on temperature. A boundary plane heated locally circle zone at given temperature as function radius. solution obtained for any describes the heating zone. Two special cases are investigated detail, namely Case 1 constant and 2 radius, r. exterior assumed zero. Hankel transform method applied to obtain formulated problem. effect properties distributions considered body...

Abstract This paper presents a novel approach to the analysis of nanofluids by using nonlinear multifractal algorithm. Multifractal allows present detailed local descriptions complex scaling behavior spectrum singularity exponents. Nanoliquids prepared from nanoparticles SiO2 (~0,01g) suspended in 100 ml demineralized water and 99,5% isopropanol were subjected classical methods analysis: determination contact angle, zeta potential, pH, examination with particle size analyzer. The obtained...
Abstract The two-phase flow patterns (air–water) in horizontal square minichannel (3 × 3 mm) has been analysed. multifractal analysis of pressure drop fluctuations was used for qualitative assessment patterns. results the complexity using spectral width ( Δh ) are presented. proposed method allows us to identify following patterns: micro-bubbles flow, micro- and minibubbles mini-bubbles with confined bubbles slug stratified flow. obtained confirm that this type can be considered as an...
