“…The high-resolution spectrum for the O 1s peak ( Figure 3 c) is the convolution of three peaks. The two low energy peaks are related to the TiO 2 metal oxide bonds [ 37 ]. The third contribution has the highest energy and is related to the oxygen of the Ti–OH bond [ 36 ].…”

Background Biofunctionalization of titanium surfaces can improve host responses, especially considering the time for osteointegration and patient recovery. This prompted us to modify titanium surfaces with alendronate and albumin and to investigate the behavior of osteoblasts on these surfaces. Methods The biofunctionalization of titanium surfaces was characterized using classical physicochemical approaches and later used to challenge pre-osteoblast cells up to 24 h. Then their viability and molecular behavior were investigated using mitochondrial dehydrogenase activity and RTq-PCR technologies, respectively. Potential stimulus of extracellular remodeling was also investigated by zymography. Results Our data indicates a differential behavior of cells responding to the surfaces, considering the activity of mitochondrial dehydrogenases. Molecularly, the differential expression of genes related with cell adhesion highlighted the importance of Integrin-β1 , Fak, and Src . These 3 genes were significantly decreased in response to titanium surfaces modified with alendronate, but this behavior was reverted when alendronate was associated with albumin. Alendronate-modified surfaces promoted a significant increase on ECM remodeling, as well as culminating with greater gene activity related to the osteogenic phenotype ( Runx2 , Alp , Bsp ). Conclusion Altogether, our study found interesting osteogenic behavior of cells in response to alendronate and albumin surfaces, which indicates the need for in vivo analyses to better consider these surfaces before clinical trials within the biomedical field.

“…Thus, it is urgent to remove organic dyes from water and to promote the proper wastewater treatment of the contaminated waters. In order to mitigate this issue, several methodologies are currently being studied and employed for the degradation and/or removal of these dyes: ozonation [18][19][20], electrochemical oxidation [21], bacterial and/or fungal degradation [22,23], biosorption [24], phytoremediation [25] and photocatalysis [26][27][28]. From those, photocatalysis has the advantage to allow for complete mineralisation of the dyes, using low-cost catalyst system and relatively simple setups.…”

Meso-N-TiO 2 nanocatalysts (Nx-MT) were successfully synthesized through evaporation-induced self-assembly (EISA) method by using urea as the nitrogen source and Pluronic F127 as the templating agent. Through a series of characterizations and degradation of rhodamine B under simulated sunlight, the roles of mesoporous and N-doping in the Nx-MT nanocatalyst were evaluated. The Nx-MT exhibited enhanced photocatalytic activity due to the comprehensive effect of mesopores and N-doping. The effects of calcination temperature and N concentration on the performance of the catalyst were studied. Besides, the relationship between the pore volume of Nx-MT and the catalytic reaction rate was clarified. Moreover, the turnover number (TON) was used to evaluate the effect of the amount of nitrogen doping on the catalytic activity per active site.
