Quantitative assessment of atmospheric emissions of toxic heavy metals from anthropogenic sources in China: historical trend, spatial distribution, uncertainties, and control policies
Hezhong Tian,Chuanyong Zhu,Jiajia Gao,Ke Cheng,Ke Cheng,Jian Hao,Kaicun Wang,Shenbing Hua,Yongyan Wang,Junrui Zhou +9 more
TL;DR: In this paper, the authors established the multi-year comprehensive atmospheric emission inventories of 12 typical toxic heavy metals (Hg, As, Se, Pb, Cd, Cr, Ni, Sb, Mn, Co, Cu, and Zn) from primary anthropogenic activities in China for the period of 1949-2012 for the first time.

Tribological behaviour of self-lubricating materials at high temperatures
TL;DR: Self-lubricating materials are becoming more widespread in fields like metal forming or power generation due to the inability to use conventional lubricants in high-temperature (HT) applications as discussed by the authors.

Braking pad-disc system: Wear mechanisms and formation of wear fragments
Piyush Chandra Verma,Luca Menapace,Andrea Bonfanti,Rodica Ciudin,Stefano Gialanella,Giovanni Straffelini +5 more
TL;DR: In this paper, a commercial friction pad material dry sliding against a cast iron disc was used to investigate the effect of some components of the pad material on the dynamic formation of tribological layer and wear debris.

Discrete numerical model for granular assemblies.
Peter Cundall,Otto D. L. Strack +1 more
TL;DR: The distinct element method as mentioned in this paper is a numerical model capable of describing the mechanical behavior of assemblies of discs and spheres and is based on the use of an explicit numerical scheme in which the interaction of the particles is monitored contact by contact and the motion of the objects modelled particle by particle.

On the nature of tribological contact in automotive brakes
TL;DR: In this paper, the authors give a general view of the contact situation of organic binder brake friction materials against cast iron discs, with special emphasis on many mechanisms for contact surface variations and the corresponding variations of the coefficient of friction.

Friction and wear behaviors of nanocrystalline surface layer of pure copper
TL;DR: In this article, surface mechanical attrition treatment (SMAT) was employed to fabricate a nanocrystalline surface layer on a pure copper plate and the tribological behavior of the surface layer was investigated under dry conditions.
