Korfball (Dutch: korfbal [ˈkɔr (ə)vbɑl]) is a ball sport, with similarities to Netball and Basketball and Ringball. The objective is to throw a ball into a netless basket that is mounted on a 3.5 m (11.5 …

2019年5月5日 · In this work, ball milling was used to synthesize COF by mechanochemical reaction between 1,3,5-triformylphloroglucinol (Tp) and melamine (MA) at ambient temperature. Different routes (liquid-free, solvent-assisted and catalyst-assisted) and proportions of liquids (solvents or catalyst) were investigated.

2021年6月7日 · The coefficient of friction (COF) is a key factor to estimate the performance of ball screws. Pieces of research focus on the experimental study of the COF, leading to the COF chosen empirically in many studies.

2024年12月1日 · Schematic representation of a ball-milling process for the morphology reconstruction of COF-BTD (a), and morphology retention for COF-TFB and COF-PD (f). The lowest unoccupied molecular orbital (LUMO) and the highest occupied molecular orbital (HOMO) of the unit of COF-BTD (b), COF-TFB (g) and COF-PD (k).

Korfball is a ball sport played by hand. It takes a few moments to learn, but a lifetime to perfect. By passing and quick movement players must elude their personal opponents to shoot the ball through a korf – the Dutch word for basket. In the standard game, teams consist of eight players – four male and four female.

2018年1月1日 · The results show that the water-based nanolubricants with concentrations of 0.4–8.0 wt% TiO2 can significantly reduce the coefficient of friction (COF) on the two types of disks.

Tennis courts are normally classified as fast or slow depending on whether the coefficient of sliding friction (COF) between the ball and the surface is respectively small or large.

korfball, game similar to netball and basketball, invented in 1901 by an Amsterdam schoolmaster, Nico Broekhuysen. It was first demonstrated in the Netherlands in 1902 and was played on an international level, primarily in Europe, by the 1970s. It was devised as a game for both sexes.

To read the data, access the “COF (year)” folder on the (P:) drive and look for the ball you need and double click to bring up the graphs. The zero-baseline reading can be seen at the beginning...
