The distribution, pollution level, sources and health risk of Hg, As, Cd, Cu, Cr, Ni, Mn, Fe, Pb,
Sb and Zn in urban street dust were investigated. X-ray diffraction analysis of dust samples …

In the recent years, numerous studies have been done on Stirling cycle and Stirling engine
which have been resulted in different output power and engine thermal efficiency analyses …

Nanoparticles containing metals in their structure constitute an increasingly large group of
substances present in the air. They come from both natural and anthropogenic sources. The …

A kind of gC 3 N 4/SnS 2/SnO 2 nanocomposite was firstly prepared by solvothermal method
at 140° C for 4 h after 30 min ultrasonic irradiation. X-ray photoelectron spectroscopy (XPS) …

Significance of reactive oxygen species (ROS) in subsurface has been increasingly
documented in recent years, whereas the mechanisms controlling ROS production and …

In this communication, the optimal power of an endoreversible Stirling cycle with perfect
regeneration is investigated. In the endoreversible cycle, external heat transfer processes …

Urban air particulate pollution is a known cause for adverse human health effects worldwide.
China has encountered air quality problems in recent years due to rapid industrialization …

The aim of this study was to determine ambient concentrations of As (III) and As (V); Cr (III)
and Cr (VI) species-bound to PM 1 and PM 2.5 and to assess the incremental lifetime cancer …

Large amounts of chromium (Cr) compounds are used for manufacturing of various products
and various chemical processes. Some inevitably find their way into the environment …

Reactive oxygen species (ROS) production in O2-perturbed subsurface environments has
been increasingly documented in recent years. However, the constraining conditions under …
