Water-based ink in low-energy surface wetting more difficult and hinder its application. In order to solve water ink in low-energy on the surface wettability problem, change the kind of cosolvent, kind and content of surfactants prepared ink. They were tested in low-energy CD the surface contact Angle to examine wettability of ink, test the surface tension, ink affecting wettability factors were analyzed. Results show that: in water-based ink add isopropyl alcohol, flow ping agent 432 and substrate wetting agent 245, can better improve its surface wettability in low-energy, and base material wetting agent 245 content about 1.25% wet effect is good.

Electrospinning is a highly efficient technology for fabrication of a wide variety of polymeric nanofibers. However, the development of traditional needle-based electrospinning has been hampered by its low productivity and need of tedious work dealing with needles cleaning, installation and uninstallation. As one of the most promising needleless electrospinning means, bubble electrospinning is known for its advantages of high productivity and relatively low energy consumption due to the introduction of a third force, air flow, as a major force overcoming the surface tension. In this paper, the restrictions of conventional electrospinning and the advantages of needleless electrospinning, especially the bubble electrospinning were elaborated. Reports and patents on bubble-spun nanofibers with unique surface morphologies were also reviewed in respect of their potential applications.

The structure and energetics of Pd N (N = 5–80) clusters have been studied extensively by a Monte Carlo method based on Sutton–Chen many-body potential. The basin-hopping algorithm is used to find the low-energy minima on the potential energy surface for each nuclearity. A variety of structure types (icosahedral, decahedral and fcc closed-packed) are observed for Pd clusters. Some of the icosahedral global minima do not have a central atom. The resulting structures have been compared with the previous theoretical results.

In order to enhance the adhension of ink, base ink was prepared with proper pigment and grinding resin, as well as dispersing agent, then compounded it and film-forming resin. The paper has studied the major factors, including grinding resin, film-forming resin and additives, which influenced the adhension of water-based ink on UV varnish. The results indicated that the content and the variety of grinding resin had a certain influence on the adhension of water-based ink. Besides, since the structure of film-forming resin is different, it has a significant effect on the adhension of water-based ink with the change of the variety of resin. Whats more, additives, which could decrease the surface tension of ink effectively and made the ink intend to adhere on UV varnish easily, is also an important factor that influences the adhension of the water-based ink on UV varnish.

This study used water to extract substances from hulls of soap nut fruits (Sapindus Emarginatus) and licorice root (Glycyrrhizaglabra L.) found in Thailand to remove waxes in cotton scouring process. CMC value from soap nut fruits were found to be 6 mg/ml with surface tension of 54.67 mN/m and can be used as wetting agent when the temperature is lower than 70 °C. CMC value from licorice root was 10 mg/ml with surface tension of 51.50 mN/m and can be used as wetting agent at temperature higher than 95°C. The results exhibited that both substances can be used to remove waxes in cotton scouring process. At the 40% of substance powder by fabric weight, the cotton fabric absorbed water in 5 seconds.

Data retrieved from the Cambridge Structural Database for crystal structures containing (μ-diphenylphosphido) metal complexes, [M 2{μ-PPh2}] (where M is a d-block element), have been analysed to evaluate the conformational behaviour of these species. The observed distribution of torsion angles about the P—C bonds has been compared with the potential energy surface (PES) for phenyl rotations in a representative species [(AuBr)2{μ-PPh2}]− computed using the universal force field. Good agreement was obtained between the low-energy (<8 kJ mol−1 above the global minimum) regions of the PES and the occupied regions of the two-dimensional P—Ph rotor conformation space. Phenyl ring rotations occur by coupled, geared disrotatory and uncoupled conrotatory motions of the phenyl groups in this and other classes of PPh2 rotors.

AbstractThe article focuses on the Direct Drive Rotary Friction Welding of ultrafine-grained copper rods, which feature increased mechanical properties and good electrical properties, yet are limited in size. The use of UFG metals is often limited by the too small dimensions of semi-finished elements produced by SPD methods. Therefore, the production of finished machine parts from UFG metals is currently economically unjustified. Dismissal of dimensional limitations can be done by introducing joining to technological processes. The proposed joining method does not lead to a melting of the material in the joining zone or excessive degradation of the UFG microstructure. To obtain the best results, the research used the method of low-energy welding of two kinds of specimens: with a flat or a conical contact surface. In the article, the authors present, by means of metallographic microsections and microhardness measurements, the influence of rotational speed, welding pressure and conical shape contact surface on the quality of the obtained joints. The conducted research made it possible to obtain good quality joints whose microhardness is reduced only by about 10% in comparison with the base material and the tensile strength dropped from only 397–358 MPa.
