Various standard methods have previously been used for the synthesis of nanoparticles that produce unhealthy waste. They are also considered unsafe and expensive methods. An alternative technology is needed to synthesize nanoparticles that consume less energy and are more environmentally friendly. In this research, a TiO2/ZnO nanocomposite has been synthesized, which was produced with efficient energy and no environmental pollution using an easy and fast method (electrochemical). Additionally, dye-sensitized solar cells (DSSCs) have been fabricated from TiO2/ZnO nanocomposite which was synthesized by a new green method and pigments (methylene blue as a chemical dye and chlorophyll as a natural dye). These DSSCs were characterized by their high ability to absorb ultraviolet energy, where the efficiency of energy conversion η of ITO-TiO2/ZnO were approximately 2.08, and 3.04% with chlorophyll and methylene blue, respectively, showing that η of ITO-TiO2/ZnO with methylene blue was the best.

Diabetes is a complex metabolic disruption affecting the glucose level of the human body. Intracellular hyperglycemia promotes mitochondrial reactive oxygen species (ROS) production, ROS directly improve the expression of inflammatory, these inflammations are associated with the level of soluble receptors for advanced glycation end-products (sRAGE) in serum. in this work assessed the level of (sRAGE) and study its potential as a biomarker for diabetes mellitus. The research included 108 Iraqis between the ages of (35-65) years of both sexes. The individuals were divided into two groups, (63) with type 2 diabetes mellitus (T2DM) and (45) control group, most of the tests serum have been measurements by colourimetric methods, and sRAGE levels in serum were evaluated by ELISA Technique. The results of the investigation showed that the sRAGE mean was more elevated compared to the mean of the control group (p < 0.00001). Statistical study of Pearson's correlation illustrated that the sRAGE level is high positively with FBG, and HBA1C (r = 0.878, p < 0.00001), (r = 0.422, P=0.05) respectively. While, negatively correlation with insulin level (r = -0.204, p = 0.010). Furthermore, most the sRAGE level denoted a positive significant correlation with kidney function parameters inclusive urea, creatinine, and ACR, except eGFR was a negative significant (r = 0.422, p = 0.05), (r = 0.501, p = 0.01), (r = 0.435, p = 0.030), (r = -0.539, p = 0.011) respectively. These results support a strong relationship between serum sRAGE level and indicators of hyperglycemia, so we can conclude that it is a great biomarker for predicting of diabetes mellitus.

Different standard methods have previously been used for the synthesis of nanoparticles that produce unhealthy waste. They are also considered unsafe and expensive methods. An alternative technology is needed to synthesize nanoparticles that consume less energy and are more environmentally friendly. In this research, CuO and TiO2 nanoparticles have been synthesized, which produce good energy and no environmental pollution using an easy and fast method (electrochemical). Additionally, dye-sensitive solar cells (DSSCs) have been fabricated from CuO and TiO2 nanoparticles, which were synthesized by a new green method, and the pigments methylene blue as a chemical dye and chlorophyll as a natural dye. These DSSCs were characterized by their high ability to absorb ultraviolet energy, where the efficiency of energy conversion (ɳ) of ITO-CuO was approximately 3.69 and 2.61% with methylene blue dye and chlorophyll dye, respectively, while the efficiency of ITO-TiO2 was 3.20 with MB and 2.08% with chlorophyll. The results showed a significant progression of efficiency of energy conversion using methylene blue dye in both cells, and the DSSC using CuO was the best
