Opis:
Badano empiryczne zależności między granicznym kątem zwilżania powierzchni węgla θ a średnim napięciem powierzchniowym zwilżania γc. Aby uzyskać odpowiednie dane badano 20 próbek węgli kamiennych o różnym stopniu zmetamorfizowania. Stwierdzono zależność funkcyjną między badanymi parametrami, którą ilościowo opisano równaniem regresji. Wykorzystując wartości γc niejednorodności energetycznej w zbiorze ziaren σγc badanych węgli oraz wyżej wymienione równanie określono przedziały wartości, w których mogą się mieścić graniczne kąty zwilżania w zbiorze ziaren danego węgla. Wyznaczono także wartość napięcia powierzchniowego zwilżania γc(θ = 0), powyżej której kąt zwilżania powierzchni węgla wynosi zero. Dla badanych węgli wartość ta wynosi 57,838 mJ/m2. Wykorzystując krzywe rozkładu energii powierzchniowej w zbiorze ziaren, określono udział w danym zbiorze ziaren o kącie zwilżania równym zero.
Empirical relationships between the contact angle of coal surface θ and the mean critical surface tension of wetting γc were investigated. In order to obtain suitable data, 20 hard coal samples of different rank were tested. The functional relationship between investigated parameters was stated, described quantitatively by means of a regression equation. Using the γc. and energetic nonhomogeneity values in the set of particles σγc of tested coals as well as the above mentioned equation, the intervals of values were determined, in which the contact angles in the set of grains of the given coal can be contained. Moreover, the value of surface tension of wetting γc(θ = 0), above which the contact angle of coal surface is equal to zero, was calculated. For tested coals this value amounts to 57.838 mJ/m2. Using curves of surface energy distribution in the set of particles, the share of particles with contact angle equal to zero in the given set was determined.

Bubble Coalescence Time Measurement
Opis:
An efficiency of flotation process is strongly dependent upon the collecting ability of air bubbles. On the other hand, the liquid film formed beetween two fully or partially mobile air/liquid interfaces being in contact has low stability, which leads to fast liquid drainage. Therefore, when they approach to each other, they tend to coalescence. Therefore, bubble coalescence is usually controlled with frothers in flotation process. Meanwhile, it is known that dissolved ions inhibit bubble coalescence. In this study, the bubble coalescence in the presence of MIBC was determined using a novel technique with a modified bubble-particle attachment timer. Additionally, the effect of NaCl and CaCl2 on bubble behavior was investigated along with surface tension and bubble coalescence time aspects. As a result of study, it is seen that the bubble coalescence time can be successfully determined with a bubble-bubble coalescence timer.

Opis:
Flotation of soluble salts such as borax, potash, and trona is carried out in their saturated solutions. The high ion concentration of the flotation suspension can affect the floatability of the minerals as well as the coalescence behaviors of the bubbles. The bubble coalescence can be inhibited in the presence of dissolved ions at high ion concentrations as well as with the use of surfactants. In this study, the effect of the mixtures of KCl, NaCl, and dodecyl amine hydrochloride (DAH) on air/water interface was investigated with surface tension and bubble coalescence time measurements for potash flotation. The surface tension measurements indicated that lower surface tension values obtained with mixed KCl and NaCl solutions than their single solutions. In addition, the surface tension of the mixed KCl and NaCl solutions increased with the NaCl and the ionic strength of the solution. The dynamic surface tension measurements indicated that while ion adsorption on air/water interface was so fast, DAH molecules required more time for adsorption probably related to the viscosity of the solution. In addition, the bubble coalescence time measurements showed that the bubble coalescence could be inhibited with the use of DAH in the absence and presence of KCl and NaCl. In the absence of DAH, the bubble coalescence time was determined as 100 ms, 270 ms, and 650 ms, respectively for 100% KCl, 100% NaCl, and 50%KCl+50% NaCl salt solutions. Therefore, the trend in the success of the salt solutions for the inhibition of bubble coalescence can be written as 100%KCl<50%KCl+50%NaCl<100% NaCl according to the bubble coalescence time. The results of this study indicated that there was no clear relationship between the surface tension and the inhibition of the bubble coalescence. However, the bubble coalescence time measurements showed that while the bubble coalescence time was 650 ms in the presence of Na+ ions, it was 100 ms in the presence of K+ ions 100 ms. It can be concluded from the results obtained from this study that the bubble coalescence phenomena may be managed by the specific ion pairing types in solutions which significantly affect the flotation recovery of minerals.

Influence of the binary mixtures of fluorocarbon surfactants Zonyl FSO-100  (FSO100) and Zonyl FSN-100 (FSN100) on the surface tension of the water was studied. The effectiveness of adsorption process of the surfactant at the water-air interface was calculated from the obtained values of the surface tension of studied mixtures. Also the maximum surface area per molecule of surfactant in the interfacial area  and the free energy at the water-air interface  were determined. Moreover, the existence of synergetizm or antagonism effect, which reduces the surface tension of the water was examined. On the basis of the Rosen's model parameter the values of intermolecular interactions in the mixed monolayer adsorption were calculated.

Opis:
Napięcie powierzchniowe cieczy ma istotny wpływ na transport masy i energii na granicy międzyfazowej. W superkondensatorze, gdzie ładunek gromadzony jest dzięki istnieniu podwójnej warstwy elektrycznej na granicy faz pomiędzy elektrodą a elektrolitem, napięcie powierzchniowe elektrolitu wpływa na zwilżalność i powinowactwo z materiałem węglowej elektrody. Poprawa zwilżalności elektrody przez elektrolit zwiększa dostępność porowatych powierzchni elektrod węglowych dla jonów elektrolitu. Dzięki temu możliwie jest zgromadzenie większej liczby ładunków oraz obniżenie łącznej, wewnętrznej oporności urządzenia. W pracy przedstawiono wpływ zmniejszenia napięcia powierzchniowego – poprawę zwilżalności materiału węglowego elektrolitem na właściwości elektrochemiczne superkondensatora. Zmiany napięcia powierzchniowego realizowano dodając do elektrolitu surfaktanty. Surfakanty dodawano poniżej krytycznego stężenia micelarnego, aby uniknąć tendencji do tworzenia agregatów, które mogą blokować pory węglowej elektrody. Właściwości elektrochemiczne celki kondensatora sprawdzono metodami woltametrii cyklicznej, galwanostatycznego ładowania i rozładowania oraz spektroskopii impedancyjnej.
The surface tension of liquids has a significant impact on the transport of mass and energy at the interface. In case of supercapacitor, where the charge is collected by the existence of electrical double layer at the interface between electrode and electrolyte, surface tension of an electrolyte reflects the wettability and affinity for the electrode material. The improvement of the wettability of electrode in the electrolyte increases the access of electrolyte to the surface of porous carbon electrode and accordingly better charge accumulation is achieved. It also results in a lower internal resistance of cell. In this work, impact of decreasing surface tension and increasing the electrolyte wetting properties on the electrochemical properties of supercapacitor were investigated. Improvement of these properties has been achieved through the inclusion of surfactant to electrolyte. Surfactants were added under critical micelle concentrations (CMC) to avoid surfactant tendency to form aggregates, that can block the pore in carbon electrode. Properties of electrochemical capacitor cell by cyclic voltammetry methods, galvanostatic charge and discharge and impedance spectroscopy were measured.

Opis:
Inhaled mineral nanoparticles which are deposited on the lung surface may influence the gas/liquid barrier and the pulmonary surfactant (PS) which constitutes the vital element of the respiratory system. This research is focused on the physicochemical effects caused by selected clay nanoparticles (bentonite, halloysite, montmorillonites) interacting with PS and changing its original surface activity. Using three measuring methods (pulsating bubble technique, Langmuir balance and drop shape analysis), we demonstrated the influence of different mineral nanoparticles on the dynamic surface tension of animal-derived PS material (Survanta®) and main surfactant phospholipid (DPPC). The results which are dependent on material properties and concentration allow to hypothesize possible pathways of health effects from inhalation of mineral nanoparticles. This may help to set the guidelines in defining occupational safety standards and methods of protection of the respiratory system against inhaled mineral dusts.

A simple theoretical model considering cell membrane mechanosensitivity can accurately describe published experimental data on membrane area creeping and recovery, and on osmotic expansion and rupture. The model to data fit reveals real values of membrane tension and elasticity modulus, and the parameters describing membrane organization and kinetics of mechanosensitive membrane traffic, including small solute transport, water permeability, endocytosis, exocytosis, and caveolae formation. This estimation allows for separation and quantitative analysis of the participation of different processes constituting the response of plasmalemma to short time-scale membrane load. The predicted properties of the model were verified for membrane stretching at different osmotic pressures. Finally, a simple hypothesis concerning stressed cell membrane breakdown is postulated.

The paper discusses the results of the studies on the surface properties and lubricating abilities of five ionic liquids compared to a high quality gear oil: Mobilube 1SHC 75W90 and two base oils: PAO-6 and SN-650. The investigated ionic liquids were: 1) tetrafluoroborate 1- benzyl-3-methylmidazolium, 2) bis (trifluoromethylsulfonyl) imide 3-methyl-1- propylpyridinium, 3) bis (trifluoromethylsulfonyl) imide 1,2-dimethyl-3-propylimidazolium, 4) bis (trifluoromethylsulfonyl) imide trihexyltetradecylphosphonium), 5) tetrafluoroborate trihexyltetradecylphosphonium. The density, surface tension and wetting angle as well as dynamic and kinematic viscosity were measured. Next, the lubricity properties were evaluated using the four-ball tester. The research results showed the more better lubricity properties of ionic liquids than the base oils. The research results showed the more better lubricity properties of ionic liquids than the base oils. The ionic liquids had the comparable properties to a high quality gear oil. Obtained results of these preliminary studies confirmed a possibility of using selected ionic liquids as new lubricants. These compounds can probably replace the lubricants used so far and find a wide scope of application in lubrication technology in the future. However, particular implementations require further complex studies.

In the paper the investigative results of lubricity and surface properties for four synthetic perfluoropolyether (PFPE) oils, comparing with the high quality gear oil Mobilube 1SHC 75W-90 and two base oils PAO-6 and SN-650, are discussed. The goal of the research was to identify anti-wear and anti-seizing properties of PFPE oils correlation with their surface-energetic and viscosity-temperature properties. Modern test equipment was used for perfomed research. The following apparatuses were used: KSV Sigma 701 and KSV CAM 100 made in Finland, AMVn Anton Paar made in Austria, and T-02 four-ball apparatus made in Poland. Measurement of density, surface tension and wetting angle were done with the use of KSV Sigma 701 apparatus, according to its instruction manual. The static wetting angle on the real surface of a steel plate was determined with the use of KSV CAM 100 apparatus. The dynamic viscosity of the tested compounds was determined with the use of AMVn microviscometer. The tests of the lubricity properties of the synthetic oils and comparative liquids were perfomed with the use T-02 four-ball tester. The investigative results showed that PFPE oils can be used particularly in hydrodynamic and elastohydrodynamic lubrication.

The micro air nucleus widely distributed in the ocean is a necessary condition for the cavitation of hydraulic machinery in seawater. In order to study the stability of air nucleus in seawater and cavitation inception, the computational domain of water molecules with air nucleus was studied using the method of molecular dynamics simulation, and the transient characteristics of air nucleus in liquid water were obtained. The key factors influencing nuclei stability were analyzed. The results showed that air nucleus with a certain mass could maintain the dynamic equilibrium in liquid water. The internal density of air nuclei had a critical value that allowed the nuclei to stably exist in water. The air nuclei mass was the decisive factor in its equilibrium volume in water, and the two were positively correlated. The internal density of air nuclei was negatively correlated with the nuclei radius when the nuclei was stable in water. Liquid surface tension was an important factor affecting the stability of the air nuclei. The larger the initial radius of nuclei, the smaller the water pressure, and the more likely the cavitation occurs.

Positron lifetime spectra were measured for a series of odd-numbered liquid n-alkanes (C7H16, C9H20, C13H28 and C19H40) in a broad range of temperature. According to the “bubble model” the ortho-positronium (o-Ps) lifetime is determined by surface tension. Bubble radius was calculated using the Tao-Eldrup model and compared to the radius expected from the surface tension of liquid. The radii are not identical, their difference rises with temperature. If one assumes the difference of radii as constant, the o-Ps lifetime calculated from the Tao-Eldrup model rises faster than the experimental one. The distinct rise of the difference of radii has no physical explanation in the accepted o-Ps annihilation model. This effect can be the result of radiation chemistry processes not taken into account so far in the bubble model.

Determination of the physico-chemical interactions between liquid and solid substances is a key technological factor in many industrial processes in metallurgy, electronics or the aviation industry, where technological processes are based on soldering/brazing technologies. Understanding of the bonding process, reactions between materials and their dynamics enables to make research on new materials and joining technologies, as well as to optimise and compare the existing ones. The paper focuses on a wetting force measurement method and its practical implementation in a laboratory stand – an integrated platform for automatic wetting force measurement at high temperatures. As an example of using the laboratory stand, an analysis of Ag addition to Cu-based brazes, including measurement of the wetting force and the wetting angle, is presented.

Uzyskane wyniki pozwalają stwierdzić, że kolagen natywny wykazuje małą zdolność obniżania napięcia powierzchniowego, ale poddanie go niewielkim modyfikacjom (działanie temperatury) skutkuje poprawą jego właściwości powierzchniowych.
The aim of research presented in this paper was to determine (using the method of droplet shape analysis) surface activity and rheological properties of adsorption layers formed by type I collagen derived from calf leather. The obtained results imply that native collagen shows rather weak surface properties. However, even simple modification of its structure (temperature treatment) results in improvement of its surface activity and mechanical properties of adsorbed layers.

Wettability of poly(tetrafluoroethylene) (PTFE) by aqueous solutions of binary mixtures composed of sodium bis(2-ethylhexyl) sulfosuccinate (AOT) with polyoxyethylene (23) lauryl ether (Brij 35) was considered on the basis of the measured values of contact angle and surface tension. It was shown that the value of the critical surface tension of PTFE surface wetting at the studied system (23.5 mN/m), does not depend on the concentration and composition of the binary mixtures of studied surfactants in water, and it was higer than the surface tension of PTFE (20.2 mN/m). The best wettability of polytetrafluoroethylene (PTFE) by studied aqueous solutions of binary surfactants mixtures occurs at the mixtures concentration corresponding to the critical micelle concentration of their solutions.
