• passages). A microcultural MTT test was used for the estimation of the number of metabolizing cells both in control and in culture containing non-coated and surface-modified γ-Fe2O3 particles. In a 96-well plate without surface treatment, 4BL cells were cultivated in standard DMEM medium with 10% fetal

• presented by Lin [10]. Theoretically, surface treatment can effectively control the band gap of nano BN and plays a crucial role of engineering their electrical and electronic properties. For example for BN nanotubes (BNNT), 50% tube surface coverage with chemisorbed hydrogen atoms would cause the BN band

• addition to the growth parameters in ALD, such as temperature and number of cycles, pre-treatment of the surface of the CNTs by using O2 plasma is found to have an effect on the nucleation and morphology of TiO2. The nuclei density is significantly increased after the surface treatment, probably due to the

• such rare-earth materials [8]. To reduce the usage of the CeO2, many groups have attempted to develop alternative polishing pads [9] and slurries [10]. Watanabe et al. developed a surface treatment for SiC and diamond that uses a photocatalytic effect [11]. To induce this photocatalytic effect, they

In the first method, the surface treatment of the particles with different alcohols is investigated as a strategy to impede the access to the
