TL;DR: The interpretation of the surface chemical states of amorphous boron carbide films as revealed by X-ray photoelectron spectroscopy (XPS) was investigated in this paper.

TL;DR: In this paper, a new approach for the preparation of palladium nanoparticles in water from a renewable source, 2-hydroxypropyl-a-cyclodextrin (α-HPCD), which acts both as reductant and capping agent, is presented.

TL;DR: The surface microchemical environment of graphene oxide (GO) has so far been oversimplified for understanding practical purposes as discussed by the authors, and the amount as well as the accurate identification of each possible oxygenated group on the GO surface are difficult to describe due to the complex chemical nature of the oxidation reactions but also due to several intrinsic variables related to the production and chemical processing of GO-based materials.

TL;DR: Fluorinated amorphous-carbon films (a-C:F:H) were deposited by low-power rf capacitively coupled plasma-enhanced chemical-vapor deposition using CH4-CF4 gas mixtures as discussed by the authors.

TL;DR: In this article, the effects of some deposition parameters (partial pressure of CF4 and self-bias voltage) on the microstructure, mechanical and tribological properties of a-C:H:F films are presented.
