Wearproof Composite Coatings on Ti

In this work the formation of protective coatings on VT1-0 commercially pure titanium by plasma electrolytic oxidation (PEO) and subsequent fluoropolymer treatment is presented. The structure, morphology, corrosion, and mechanical properties of the formed composite coatings were studied. It was established that PEO coatings are an excellent basis for the formation of a solid composite layer with high adhesion to its surface. The presence of polytetrafluoroethylene in the composition of the coating reduces the corrosion current density by 4 orders of magnitude and increases the wear resistance by 2 orders of magnitude in comparison with the base PEO coating.

Dual modification of LiNi0.6Co0.2Mn0.2O2 with MgHPO4 as a high-performance cathode material for Li-ion batteries

MgHPO4 has been introduced as a reactant that interacts with LiNi0.6Co0.2Mn0.2O2 (NCM622) to achieve the dual modification of Mg2+ gradient doping and Li3PO4 surface coating. The structure, morphology, elemental distribution,...

Tuneable synthetic reduced graphene oxide scaffolds elicit high levels of three-dimensional glioblastoma interconnectivity in vitro

Three-dimensional tissue scaffolds have utilised nanomaterials to great effect over the last decade. In particular, scaffold design has evolved to consider mechanical structure, morphology, chemistry, electrical properties, and of course...

Understanding the shoot sink.

To more fully understand how all the major organs of a tree interact in the semi-autonomous scheme of assimilate distribution and tree functioning, it is important to understand their development and growth behavior. This chapter presents a general description of the development and growth characteristics of the major organs (shoot and leaf) of fruit trees, including shoot structure, morphology and orientation; diurnal patterns of shoot growth; seasonal growth patterns of shoot growth and dormancy; as well as tree aging.
