Large amounts of rubber particles are dispersed into the environment due to tire wear. The rubber contains a wide range of chemicals, including several of environmental concern. The purpose of this thesis, which is based on six papers [I–VI], was to assess the ecotoxicological hazard and risk associated with tire wear particles, with a main focus on the aquatic environment. A method was develop...

Ni-P Electroless coatings provide appropriate resistance to wear and corrosion. Co-deposition of particles between layers can improve their properties, especially general corrosion and erosion-corrosion behavior by means of nano diamond as reinforcing particles. In this study Ni-P/nano diamond composite deposition were deposited on steel substrate. Structure of the coatings and corrosion r...

Multifractal scaling analysis is applied to the growing surfaces of random deposition model. The effect of number of deposited particles and lattice size on multifractal spectra is studied. Three cases of the growing surfaces are considered: (1) Same total number of particles deposited on different square lattice so that the number of particles deposited per surface site is different. (2) Diffe...

the ability of trees to trap dusts convinces their use for preventing the transport of dust over longer distances. this ability is increasingly important in threatened areas with dust invasion. the purpose of this study was to compare the size and distribution of particles deposited on the leaves surface of fraxinus rotundifolia, platanus orientalis, and robinia pseudoacacia trees, in paveh, we...

In this study, different amounts of MoS2 particles and an anionic surfactant were added to the conventional chromium electroplating bath in order to electrodeposite crack-free chromium coatings and the structure, morphology, tribology and corrosion behavior of the deposited coatings were investigated using X-ray diffraction spectroscopy, scanning electron microscopy, pin on disk ...

We have studied the presence in the environment of the polycyclic aromatic hydrocarbon benzo[a]pyrene (BaP) in the city of Granada using room-temperature phosphorescence (RTP) applied to microemulsions. A detailed study into the different compositions of several normal microemulsion together with experimental variables (heavy atom, deoxygenate agent, pH) and instrumental parameters (wavelengths...

The purpose of this study was to characterize the physical and chemical properties of particles generated from the interaction of tires and road surfaces. Morphology, size distribution, and chemical composition were compared between particles generated using different methods, including on-road collection, laboratory generation under simulated driving conditions, and cryogenic breaking of tread...
