Neonicotinoid Residues on Filter Paper Lack Insecticidal Activity.

Neonicotinoid insecticides are used against agricultural, forest, and urban insect pests. Evaluation of dry neonicotinoid residues on treated filter paper is a commonly used method to determine the toxicity of active ingredients towards target and non-target organisms. Dry residues of four neonicotinoids, acetamiprid, dinotefuran, imidacloprid, and thiamethoxam, on filter paper did not cause significant levels of mortality in Hippodamia convergens (Guérin-Méneville) (Coleoptera: Coccinellidae) and Nezara viridula (L.) (Hemiptera: Pentatomidae) when compared to paired untreated groups. Conversely, nearly 100% mortality was observed when test insects were exposed to dry neonicotinoid residues on leaf discs and glass plate surfaces. On the other hand, dry residues of the pyrethroid bifenthrin on filter paper, leaf disks, and glass plates killed significantly more test insects when compared to untreated groups. Additional bioassays tested the toxicity of acetamiprid and thiamethoxam by evaluating the toxicity of dry residues on (1) the upper and (2) lower surfaces of treated filter paper, (3) on a glass plate underneath treated filter paper, (4) on the upper surface of treated filter paper treated with insecticide and adjuvant, and (5) dried residues on a glass plate after dipping treated filter paper in water and letting the solvent dry on the inert test surface. The results indicated that neonicotinoid insecticides applied to filter paper were adsorbed. Toxic compounds possibly move in between and binding to paper fibers so that no toxic residues were left on treated surfaces. However, adsorbed insecticides were still biologically active when washed out of filter paper and dried on an inert glass surface. The results reported here clearly demonstrate that the toxicity of neonicotinoid insecticides should not be evaluated using filter paper as a test surface.

Siloxane Containing Polyether Groups-Synthesis and Use as an Anti-Biocorrosion Coating.

In the presented study, the effectiveness of a siloxane polyether (HOL7) coating on glass against microbiological colonization was assessed using microalgae as a key component of widespread aerial biofilms. The siloxane polyether was successfully synthesized by a hydrosilylation reaction in the presence of Karstedt's catalyst. The product structure was confirmed by NMR spectroscopy and GPC analysis. In addition, the thermal stability of HOL7 was studied by thermogravimetric measurement. Subsequently, the surfaces of glass plates were modified with the obtained organosilicon derivative. In the next step, a microalgal experiment was conducted. A mixture of four strains of algal taxa isolated from building materials was used for the experiment-Chlorodium saccharophilum PNK010, Klebsormidium flaccidum PNK013, Pseudostichococcus monallantoides PNK037, and Trebouxia aggregata PNK080. The choice of these algae followed from their wide occurrence in terrestrial environments. Application of an organofunctional siloxane compound on the glass reduced, more or less effectively, the photosynthetic activity of algal cells, depending on the concentration of the compound. Since the structure of the compound was not based on biocide-active agents, its effectiveness was associated with a reduction in water content in the cells.

Mechanical Properties of Glass Plate During Anticlastic Cold Bending

Anticlastic glass surfaces play a significant role in free-form glass facades. For realizing anticlastic surface, cold bending by loading at the corner of the plate is more adaptive and more economic than traditional hot bending method. Previous research on anticlastic cold bending mainly focuses on the description of instability phenomenon and qualitative analysis of parameters. However, the failure mechanisms of glass plates during cold bending and the influence of lamination remains unclear. In this paper, the anticlastic cold bending test was conducted to explore the influence of various factors, including aspect ratio, scale and composition of the plates. Subsequently, an effective finite element model was established and validated by test results, which is used for further explore the cold bending controlling condition for better engineering practice. The failure modes are considered as instability and strength failure. For laminated glass, maximum stresses can be derived from monolithic glass based on equivalent thickness method. The instability is induced by the compression area in the middle surface of glass plate which is significantly influenced by the composition of the laminates. Consequently, thin glass laminates exhibit enhanced stability because a reduced glass to PVB thickness ratio changes the compression area from bi-directional to uni-directional.

Separation and Analysis of Connected, Micrometer-Sized, High-Frequency Damage on Glass Plates due to Laser-Accelerated Material Fragments in Vacuum.

In this paper, we present a new processing method, called MOSES-Impacts, for the detection of micrometer-sized damage on glass plate surfaces. It extends existing methods by a separation of damaged areas, called impacts, to support state-of-the-art recycling systems in optimizing their parameters. These recycling systems are used to repair process-related damages on glass plate surfaces, caused by accelerated material fragments, which arise during a laser-matter interaction in a vacuum. Due to a high number of impacts, the presented MOSES-Impacts algorithm focuses on the separation of connected impacts in two-dimensional images. This separation is crucial for the extraction of relevant features such as centers of gravity and radii of impacts, which are used as recycling parameters. The results show that the MOSES-Impacts algorithm effectively separates impacts, achieves a mean agreement with human users of (82.0 ± 2.0)%, and improves the recycling of glass plate surfaces by identifying around 7% of glass plate surface area as being not in need of repair compared to existing methods.

Experimental Study on the Adhesion of Abalone to Surfaces with Different Morphologies.

To date, research on abalone adhesion has primarily analyzed the organism's adhesion to smooth surfaces, with few studies on adhesion to non-smooth surfaces. The present study examined the surface morphology of the abalone's abdominal foot, followed by measuring the adhesive force of the abalone on a smooth force measuring plate and five force measuring plates with different surface morphologies. Next, the adhesion mechanism of the abdominal foot was analyzed. The findings indicated that the abdominal foot of the abalone features numerous stripe-shaped folds on its surface. The adhesion of the abalone to a fine frosted glass plate, a coarse frosted glass plate, and a quadrangular conical glass plate was not significantly different from that on a smooth glass plate. However, the organism's adhesion to a small lattice pit glass plate and block pattern glass plate was significantly different. The abalone could effectively adhere to the surface of the block pattern glass plate using the elasticity of its abdominal foot during adhesion but experienced difficulty in completely adhering to the surface of the quadrangular conical glass plate. The abdominal foot used its elasticity to form an independent sucker system with each small lattice pit, significantly improving adhesion to the small lattice pit glass plate. The elasticity of the abalone's abdominal foot created difficulty in handling slight morphological size changes in roughness, resulting in no significant differences in its adhesion to the smooth glass plate.

Dynamic imaging of three-dimensional temperature field via three-directional wavelength modulated lateral shearing interferometry

A three-directional wavelength modulated lateral shearing interference system was proposed for the dynamic three-dimensional visualization of a temperature field. The laser emitted from a distributed feedback (DFB) laser was divided into three beams by a fiber beam splitter. The beams were spatially expanded and passed through the flame in three directions of 0°, 120° and 240°, respectively. The three interferograms formed by reflections from the front and back surfaces of the parallel glass plates were spatially converged into the lens of a high-speed camera. Multiple plane mirrors were utilized to reflect the beams. The size of the region of interest (ROI) was −20 ∼ 20 mm in both x and z directions and 5 ∼ 30 mm in y direction, with a spatial resolution of 200 μm in all directions. A three-dimensional sensitivity matrix was modeled, and the simultaneous algebraic reconstruction technique (SART) was used for layer-by-layer imaging to achieve three-dimensional flame monitoring. Numerical simulations verified the effectiveness of the algorithm qualitatively and quantitatively. In experiments, the temperature distributions of four cases of flames, namely, steady diffused flame, partially blocked diffused flame, dynamic acoustically excited flame and the flame after ignition, were reconstructed at 1k frames per second (fps). The flame structures and temporal variations of temperature distributions were clearly visualized, demonstrating the ability of the system in fast monitoring of three-dimensional dynamic temperature fields.

Kinetic regularities of hydrometallurgical recycling of spent displays: behavior of indium

This article discusses the physicochemical regularities of indium leaching from the surface of glass plates of used displays in various acids. The glass of used displays was pre-cleaned from polarizers and crushed. Their base is comprised of silicon and aluminum oxides. Indium is presented in the form of In2O3·SnO2. Indium content in the material obtained is 174.8 mg/kg. Individual solutions of sulfuric, hydrochloric and methanesulfonic acids were used as leaching agents. The influence of concentrations of the mentioned acids (0.1–1.0 N), leaching duration (10–60 min), temperature (298–353 K) and liquid-to-solid ratio (L : S = (7.5÷15.0): 1 cm3/g) on the degree of indium extraction into solution has been determined. Partial orders of reaction in terms of CH3SO3H, H2SO4, HCl are 0.69, 0.67 and 1.10, respectively. In the course of experiments an intensive increase in indium concentration was observed in the first 20–40 min f leaching in H2SO4 and HCl solutions. The process rate then decreased and indium extraction actually did not increase, due to a fall in the amount of non-reacted indium. During leaching in 0.1–0.4 N in CH3SO3H solutions, the rate of indium dissolution did not change throughout the experiment, since the amount of non-reacted indium gas decreased insignificantly. The acids considered here can be ranked in the following ascending order of their efficiency for indium dissolution: CH3SO3H, H2SO4, HCl, which corresponds to the growth of strengths of these acids. An increase in the temperature led to a significant increase in indium extraction. The apparent activation energies of In2O3 dissolution in CH3SO3H, H2SO4, HCl solutions have were calculated as equal to 51.4, 51.2, 43.4 kJ/mole, respectively. It was established that with the use of HCl as leaching agent, the increase in the fraction of liquid phase in the slurry from 7.5 : 1 to 15 : 1 cm3/g lead to fall in indium extraction by 2.4 times and the initial leaching rate by 3.2 times. It was demonstrated that an increase in L : S during indium dissolution in CH3SO3H (from 7.5 : 1 to 15 : 1 cm3/g) and H2SO4 (from 10 : 1 to 15 : 1 cm3/g) is accompanied by insignificant changes in extraction and initial leaching rate. Therefore, the studies performed demonstrated that indium leaching from glasses of spent displays flows in mixed mode upon the use of HCl and in kinetic mode in H2SO4 and CH3SO3H solutions.

Ratiometric Luminescent Thermometer Based on the Lanthanide Metal–Organic Frameworks by Thermal Curing

The high-performance optical thermometer probes are of great significance in diverse areas; lanthanide metal-organic frameworks (Ln-MOFs) are a promising candidate for luminescence temperature sensing owing to their unique luminescence properties. However, Ln-MOFs have poor maneuverability and stability in complex environments due to the crystallization properties, which then hinder their application scope. In this work, the Tb-MOFs@TGIC composite was successfully prepared using simple covalent crosslinking through uncoordinated -NH2 or COOH on Tb-MOFs reacting with the epoxy groups on TGIC {Tb-MOFs = [Tb2(atpt)3(phen)2(H2O)]n; H2atpt = 2-aminoterephthalic acid; phen = 1,10-phenanthroline monohydrate}. After curing, the fluorescence properties, quantum yield, lifetime, and thermal stability of Tb-MOFs@TGIC were remarkably enhanced. Meanwhile, the obtained Tb-MOFs@TGIC composites exhibit excellent temperature sensing properties in the low-temperature (Sr = 6.17% K-1 at 237 K), physiological temperature (Sr = 4.86% K-1 at 323 K), or high-temperature range (Sr = 3.88% K-1 at 393 K) with high sensitivity. In the temperature sensing process, the sensing mode of single emission changed into double emission for ratiometric thermometry owing to the back energy transfer (BenT) from Tb-MOFs to TGIC linkers, and the BenT process enhanced with the increase of temperature, which further improved the accuracy and sensitivity of temperature sensing. Most notably, the temperature-sensing Tb-MOFs@TGIC can be easily coated on the surface of polyimide (PI), glass plate, silicon pellet (SI), and poly(tetrafluoroethylene) plate (PTFE) substrates by a simple spraying method, which also exhibited an excellent sensing property, making it applicable for a wider T range measurement. This is the first example of a postsynthetic Ln-MOF hybrid thermometer operative over a wide temperature range including the physiological and high temperature based on back energy transfer.

Hybrid Bio-Based Silicone Coatings with Anti-adhesive Properties.

Hybrid polysiloxanes and polysilsesquioxanes grafted with naturally occurring bioactive phytochemicals: eugenol and linalool, were synthesized and investigated with regard to their structure and properties. The two series of materials, differing in the type of inorganic structure and the content of active groups, were coated onto the surface of glass plates, and their antibiofilm activities against bacteria Aeromonas hydrophila were assessed by luminometry and fluorescence microscopy. Bioactivity was correlated with specific properties of the hybrid coatings (chemical structure, surface free energy and adhesiveness). The functionalized polysilsesquioxanes exhibited the most favorable anti-adhesive effects. Cell adhesion after 6 days of incubation, expressed as RLU/cm2, was significantly reduced (44 and 67 for, respectively, Z-E-100 and Z-L-100, compared to 517 for the control glass carrier). The surface stickiness of polysiloxane films deteriorated their anti-adhesion properties, despite the presence of a large amount of bioactive species.

Процессы на поверхности стекла при облучении электронами средних энергий

The results of experimental studies of the processes occurring on the surface of protective glasses of solar batteries and elements of reflective coatings of high-orbit artificial Earth satellites (AES) under irradiation with electrons with an energy of 30 keV are presented. The studied samples were made on the basis of K-208 glass, while the samples of reflective coatings differed in the presence of silver and stainless steel layers on the reverse surface of the glass plates, deposited sequentially by the magnetron sputtering method. Electron irradiation of the samples was carried out in a vacuum of 10–4 Pa at a particle flux density (φ) from 1·109 to 8·1012 cm–2s–1; the surfaces of the samples before and after irradiation were examined by atomic force microscopy (AFM). On the irradiated surface of glass samples, electrostatic discharges (ESD) arose, the parameters of which were characterized by oscillograms of generated electromagnetic pulses; for elements of reflective coatings, leakage currents to the metal substrate were additionally measured. It was found that changes in the structure of the irradiated surface of the samples are due to the appearance of traces of ESD and the formation of gas-filled bubbles on it, and changes in the back surface of glass plates are caused, presumably, by shock waves formed when ESD occurs on the irradiated surface. The ESD frequency and leakage currents increase with increasing electron flux density in the specified range, but these dependences differ significantly. Measurements at a constant value of φ = 2.0·1010 cm–2s–1 showed that with an increase in the electron fluence from 1014 to 5·1016 cm–2, the ESR frequency increases, but the amplitude of electromagnetic pulses decreases.

Surface Assessment of Transparent Glass Plate with Wavelength-Modulated Interferometry and Harmonic Phase-Iterative Method

Multiple reflections and nonlinearity of phase modulating need to be compensated to accurately profile the surface of the glass plate using wavelength-modulated interferometry. In this study, to assess the glass plate surface using wavelength-modulated interferometry, a new phase-iterative method insensitive to the harmonic signals and nonlinear errors was developed. We developed the harmonic phase-iterative method by combining the phase-iterative method with irradiance signal considering the harmonic components. Moreover, for suppression of the harmonic-related errors in the iterative calculation, the noble pixel-selection technique and convergence formula were combined with the phase-iterative method. For estimation of the developed iterative method, we conducted the numerical simulation and assessed the glass plate surface with the Fizeau interferometer. The simulation and assessment results demonstrated that the proposed method could perform phase extraction with improved iterative calculation and suppression of the effects of the harmonics and nonlinearity.

The effect of indium–tin oxide coatings on the formation of craters on glass surfaces under the impact of high-velocity microparticles

This article considers the problem of improved mechanical properties and protection of glass materials in optical systems of space vehicles. One the possible methods to solve the problem is the formation of multi-phase nanocomposite shock-resistant transparent coatings on the surface of glass plates. Considerable attention is paid to the application of indium–tin oxide (ITO) coatings on the surface of quartz glass pieces deposited by the method of pulsed magnetron sputtering. Such coatings demonstrate the highest properties. The optical characteristics of ITO coatings were studied in a range of wavelengths of 200–1100 nm. It was shown that in the visible spectrum they remain transparent. The structure and phase composition of indium tin oxide coating, basically, contains nanocrystalline In2O3 phase, which is indicated by the diffraction reflexes on obtained electron diffraction patterns and X-ray diagrams.It was unveiled that the deposited ITO-based coatings possess resistance to the shock impact of hyper-velocity iron microparticles. They can appreciably reduce surface density of the craters formed on the surface of glass plates under the impacts of solid microparticles due to increased strength and cracking resistance of the glass specimens. The character of alteration of the crater density of the glass surface with the coating is explained by the superposition of two mechanisms: reinforcement of the surface layer of glass due to deposited nanocomposite coating and supplementary dissipation of the energy of the normal shock wave that excites generation and propagation of secondary surface waves at the interface of heterogeneous layers of the ceramic coating and quartz.

The synthesis, characterization and decontamination of surface radioactive contamination of ethyl cellulose/polyacrylate strippable detergent at low temperature

It is an important issue to handle the surface contamination of nuclear facilities in the development of nuclear industry and nuclear emergency, especially in low temperature environment. In order to solve the problem of frozen, poor film-forming and strippability of the detergent at low temperature (below 0ºC), a novel ethyl cellulose/polyacrylate detergent was synthesized by free radical polymerization from ethyl cellulose, methyl methacrylate (MMA), butyl acrylate (BA), ethyl methacrylate (EMA), and isooctyl acrylate (IOA). The wettability of the detergent on different surfaces was determined by contact angle testing method. The film-forming and peeling property, rheological property of ethyl cellulose/polyacrylate detergent at low temperature were studied and the mechanical properties of the peeling film of ethyl cellulose/polyacrylate were tested. The decontamination of simulated radionuclide on the different plates by the ethyl cellulose/polyacrylate detergent at the temperature range of − 15ºC ~ 0ºC was also explored. The mechanism of simulated radionuclide transferring and decontamination was analyzed by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscope (SEM) and energy spectrum (EDS). The results show that the detergent can not be frozen even at low temperature (−25ºC), and is easy to be sprayed, forming film and peeled off on the plates of stainless steel, ceramic tiles, glass, marble and concrete within 18 h at the low temperature range of − 15ºC ~ 0ºC. The decontamination efficiency of the ethyl cellulose/polyacrylate detergent is above 90% for radionuclide contamination on the surface of stainless steel, ceramic tiles, glass and marble plates, the decontamination efficiency on concrete is above 80%, at the temperature range of − 15ºC ~ 0ºC. The mechanism of simulated radionuclide transferring from the surface of contaminated plates into the detergent and being removed were diffusion, adhesion and embedding. Therefore, the ethyl cellulose/polyacrylate detergent has a good application prospect in surface decontamination of nuclear facility decommisioning due to its excellent fluidity, spraying, rheological property, film forming, strippable property, high decontamination efficiency at low temperature.

Residual Stress Control in Mid-infrared Laser Rounding of Glass Plate Edges by Reciprocal Scanning Assist Laser Irradiation

Light absorption depth of glasses in a mid-infrared wavelength of 2.8 μm is the same scale as thickness of glass plates used in flat panel displays. Such an absorption property allows relatively uniform heating in the thickness direction of glass plates when a mid-infrared laser is irradiated vertically to the glass plate surface. Therefore, the mid-infrared laser is convenient for edge rounding of complex shape glass plates. Application of the mid-infrared laser to the edge finishing process has been developed. However, residual tensile stress in rounded edges which weakens final products has been a problem to be solved. Simultaneous assist laser irradiation with the mid-infrared laser rounding is a candidate solution because of its controllability of residual stress. In this study, residual stress control has been examined by high-frequency reciprocal scanning assist laser irradiation. In addition, relationship between residual stress and assist heating width has been investigated by numerically and experimentally. Existence of an optimum assist heating width which minimize residual stress was confirmed. Both increase and decrease in assist heating width from the optimum width increased residual stress.

Model eye tool for retinal optical coherence tomography instrument calibration

Optical coherence tomography (OCT) has been extensively used as noninvasive tool for biological tissues owing to its three-dimensional imaging ability and high axial resolution. OCT quality assurance is vital in these occasions to keep the reliability and accuracy in medical diagnosis. It is necessary to develop a calibration tool for OCT product manufacture, calibration, and quality control. A practical tool is demanded in the OCT quality control and calibration of OCT. So far, there is no such a practical tool that can test all the key parameters of OCT. We design and fabricate a model eye tool, which has this function. The model eye comprises a doublet lens, a single filament, a piece of glass plate and the microsphere-embedded phantom. The doublets lens is bonded by two pieces of planoconvex lenses in the plane position. The first lens focuses parallel light onto the rear surface of the second lens. The rear surface marked with concentric circles serves as retina to measure the angular field of view (FOV). The small flat surface on the peak of the second lens is used to test signal to noise ratio (SNR). The single filament with 125[Formula: see text][Formula: see text]m diameter is used to check the co-alignment of preview and OCT scan. The empty chamber between the small plane of the second lens and the first surface of glass plate is used to measure the depth scaling of the OCT. The microspheres of 1[Formula: see text][Formula: see text]m diameter distributed uniformly in the phantom, which can test the lateral and the axial resolution of OCT equipment. Experimental results are presented to show the validity of the proposed tool. It is shown that the tool is able to be used in the calibration and quality control of retinal OCT.

The effect of coating material combination and encapsulation method on propolis powder properties

Effects of coating materials on emulsion, physical (moisture content, water activity, particle density, bulk properties, wettability and product yield) and chemical (total and surface phenolic content and encapsulation efficiency) properties of encapsulated propolis, rich in bioactive substances, were investigated with two different methods (spray and freeze drying). Emulsion properties have an effect on physical and chemical properties of the final product, which varied according to the encapsulation method used and the differences in coating materials combination. These variations resulted from the differences in the heat and mass transfer mechanism of the processes. The product yield of the freeze dryer experiments was generally higher than the spray dryer experiments; since the product loss in the freeze dryer method was only due to the adhesion of the emulsions to the equipment's glass plate surface. Encapsulation efficiency varied in a narrow range for both drying methods and these results were above 95%. High microencapsulation efficiency values of powders proved that the encapsulation processes are carried out effectively.

Development of a selective and highly sensitive optical chemical sensor for determination of sulfaguanidine based on a novel mixed isopolymolybdates

We report a novel sensitive and selective optical sensor based on [Eu (dmso)8] [Eu (η2NO3)2(dmso)4(α-Mo8O26)0.5] [Mo6O19] (1) for sulfaguanidine (Sg) determination in environmental water. The complex formation processes between Sg and 1 were studied spectrophotometrically, showing that the stoichiometric ratio was determined as 1:1. The sensing thin film was constructed by spin coating of 1 onto glass plate surface. The proposed membrane shows a significant absorbance signal change on exposure to buffer solution of pH 7 containing Sg. The optode surface topology reveals agglomerations after the Sg detection process proving Sg recognition by the thin film. It displays a calibration response for Sg over a wide concentration range of 10−11 M to 10−5 M with a detection limit (LOD) of 6.3 × 10−13 M and response time of 8 min. This optode exhibits good selectivity toward sulfaguanidine (Sg) in comparison with sulfamethoxazole (SMX), Cloxacillin (Clox), l-cystine (L-cys), tryptophan (tryp), NO3−, and Cl−. The proposed absorbance sensor in this work was found to be stable, has good repeatability, reproducibility and an accepted lifetime. Finally, this optode has been applied for Sg determination in mineral and tap water sample finding encouraged results.

Simultaneous thickness variation and surface profiling of glass plates using Fizeau interferometer with elimination of offset phase error

Fringe analysis using phase modulation through wavelength scanning is extensively utilized for profiling the surface and thickness variation of glass plates. However, the nonlinearity of the phase-modulation error during wavelength scanning causes an offset error in the calculated phase. Therefore, in this research, two types of 19-frame phase-extraction formulas were derived for simultaneous profiling of the thickness variation and surface of a glass plate, focusing on eliminating the offset phase error. These new formulas were visualized in the frequency domain using the Fourier description. The ability of these formulas to eliminate the offset error was confirmed through numerical error analysis. Finally, the surface and thickness variation of a glass plate were simultaneously profiled using the large-aperture Fizeau interferometer and the new 19-frame formulas. The standard deviations obtained for thickness variation and surface profiling were 4.687 and 14.421 nm, respectively, which were lower than those obtained when using other phase-extraction formulas.

Characteristics of Magneto-Rheological Elastomer under Stick-Slip Condition

This paper examines the characteristics of stick-slip phenomena between the glass plate and Magneto-Rheological Elastomer (MRE) surface. Stick-slip phenomena are the spontaneous jerking motion that occurs while two objects are sliding over each other, usually accompanied by noise. Stick-slip is generated when it involves discontinuous frictional degradation when moving from static friction to dynamic friction. The phenomena can lead to uneven wear patterns, vibration and squeal noise which cause a shorter lifespan for the corresponding mechanical elements. MREs are kind of function materials to consist of a polymeric matrix with embedded ferromagnetic particles. Mechanical properties of the MREs can be controlled by the application of magnetic fields. The magnetic field-based controllability can be applied to the control of stick-slip phenomena. The friction experiment is conducted with the Reciprocating Friction Tester (RFT). The sliding speed of the RFT should be in low-speed conditions in order to make the stick-slips relatively easy to occur. A uniform magnetic field and a weight load are applied to the MRE sample to observe the effect of various experimental parameters on the movement of the stick-slip. In addition, frictional sounds due to the stick-slip phenomenon under different loads and magnetic field strength are measured and analyzed. The results of this experiment show that as the strength of the magnetic field increases, the difference in stiffness between the wipers-glass decreases, mitigating fricatives. The result is expected to be well applied to low-noise automotive wipers based on the controllability of friction behavior and squeal noise.
