Efficiency of photo‐processes on semiconductor surfaces is typically measured under continuous irradiation of the catalyst; this can lead to determined limitations given by the substrate‐catalyst interaction. In this short review, we highlight the strengths and the weaknesses of several published studies on pollutants abatement and hydrogen production ...

Antiwear performance of ionic liquid+graphene dispersions with anomalous viscosity-temperature behavior [PDF]
New dispersions of few-layers graphene (G) in 1-ethyl-3-methylimidazolium ([EMIM]) ionic liquids (ILs) with dicyanamide ([DCA]) or bis(trifluoromethylsulfonyl)imide ([TFSI]) anions have been obtained by mechanical mixing and sonication.

Fabrication of periodic nanostructures using AFM tip-based nanomachining: combining groove and material pile-Up topographies [PDF]
This paper presents an atomic force microscopy (AFM) tip-based nanomachining method to fabricate periodic nanostructures. This method relies on combining the topography generated by machined grooves with the topography resulting from accumulated pile-up ...

Valorisation of glycerol by new mechanochemical processes [PDF]
The search for new applications of glycerol, as a chemical platform from which a broad spectrum of new valuable derivatives can be obtained, is ongoing. In the present communication, a new mechano-chemical reactor is used for the valorisation of glycerol,

Interplay between microstructural evolution and tribo-chemistry during dry sliding of metals
Understanding the microstructural and tribo-chemical processes during tribological loading is of utmost importance to further improve the tribological behavior of metals.

The role of surface roughness and slide-roll ratio in the decomposition of MoDTC in tribological contacts [PDF]
In this study, the role of surface roughness and slide-roll ratio in the decomposition and friction performance of molybdenum dialkyldithiocarbamate (MoDTC) has been investigated.

Stress-augmented thermal activation: Tribology feels the force
In stress-augmented thermal activation, the activation energy barrier that controls the rate of atomic and molecular processes is reduced by the application of stress, with the result that the rate of these processes increases exponentially with applied ...
