The effect of a static magnetic field on the hydrogen bonding in water using frictional experiments
Yongfu Wang,Yongfu Wang,Bin Zhang,Zhenbin Gong,Zhenbin Gong,Gao Kaixiong,Yujing Ou,Yujing Ou,Junyan Zhang +8 more
TL;DR: In this paper, the effect of a static magnetic field on hydrogen bonding of liquid water has been examined by frictional experiments and it was found that the friction coefficient was smaller in different intensity magnetized water than in water, and became larger with the increasing water temperature.

Friction and wear of hydrogenated and hydrogen-free diamond-like carbon films: Relative humidity dependent character
TL;DR: In this article, tribological properties of hydrogenated and hydrogen free diamond-like carbon films at various relative humidity (RH) were investigated to understand the friction mechanism in the presence of water molecules.

TL;DR: In this article, a high-performance additive of poly(α-olefin) lubricant oil (type 6, PAO-6) was proposed for industrial applications by adding 0.5% (by weight, wt%) heRGO-4, the coefficient of friction was decreased by 44% and wear scar depth was reduced by more than 90%.

Understanding the ultra-low friction behavior of hydrogenated fullerene-like carbon films grown with different flow rates of hydrogen gas
TL;DR: In this paper, a detailed investigation on the relationship between structure-performance relationship under friction and wear has been conducted, and it was found that with an increase in FL content, the friction and the wear of flullerene-like hydrogenated carbon (FL-C:H) films can reach as low as 0011 and 148×10 − 8 mm 3 /Nm, respectively.
