Summary: The range of flower and fruit colors is determined by the types of anthocyanins produced, with the degree of hydroxylation on the B-ring affecting the hue of these pigments. By genetically engineering regulatory genes and a biosynthetic gene in tomatoes, different levels of hydroxylation of anthocyanins can be generated, providing unique material for studies.

Summary: The study experimentally disproved literature hypotheses for the production of purple pigment Caput Mortuum, and found that the final color is mainly affected by the grain dimensions resulting from the annealing process. It was also determined that purple ochre could only be manufactured by starting from hematite and not from red ochre.

Summary: The traditional process of denim dyeing is environmentally damaging due to high temperature and heavy use of sodium dithionite. This study investigated the possibility of applying ultrasound in conjunction with nitrogen protection to the dyeing of cotton fabrics with indigo reduced by the reducing agent DK. Comparing with other reducing agents, reducing agent DK had stronger reducing and better properties for indigo dyed fabrics.

Summary: This study focused on the characterization of nanometric materials of the beta MnMoO4-beta CoMoO4 system prepared by co-precipitation and sol-gel routes. The results showed the formation of a continuous solid solution Mn1-xCoxMoO4 with monoclinic symmetry regardless of the synthetic route. Additionally, analysis of the chemical bonds' nature in the compounds revealed the presence of strong vibrational modes related to Mo-O-Mo, Mo-O, and Co-O-Mo.
