“…Additionally, some studies [ 3 ] confirmed that UV rays can be used to improve the color fastness properties without compromising the chemical properties of polyester fabric. One of the environmentally friendly advantages of using microwave energy is the rapid heating to high temperatures that allows for greater ease of reactions, because increasing the frequency of molecular vibrations during microwave irradiation speeds up these reactions as well as reduces the use of solvents [ 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 , 64 , 65 , 66 ]. Skin cancer and sensitive skin are primarily caused by prolonged exposure to ultraviolet radiation from sunlight.…”

Original work showed the composition of the dyes and the antimicrobial/UV protective properties of a series of dyes obtained in our laboratories over the past twelve years in an easy way using microwave technology and their comparisons with conventional methods. The results we obtained clearly indicated that by using the microwave strategy, we were able to synthesize the new disperse dyes in minutes and with a much higher productivity when compared to the traditional methods, which took a much longer time, sometimes up to hours. We also introduced ultrasonic technology in dyeing polyester fabrics at 80 °C for an environmentally friendly approach, which was an alternative to traditional dyeing methods at 100 °C; we obtained a much higher color depth than traditional dyeing methods reaching 102.9%. We presented both the biological activity of the prepared new dyes and the fastness properties and clearly indicated that these dyes possess biological activity and high fastness properties.We presented through the results that when dyeing polyester fabrics with some selected disperse dyes, the color strength of polyester fabrics dyed at high temperatures was greater than the color strength of polyester fabrics dyed at low temperatures by 144%, 186%, 265% and 309%. Finally, we presented that a ZnO or TiO2 NPs post-dyeing treatment of polyester fabrics is promising strategy for producing polyester fabrics possess multifunction like self-cleaning property, high light fastness, antimicrobial and anti-ultraviolet properties.

“…Since the first publication on microwave synthesis in 1986, the use of microwave heating in organic synthesis has become so popular that it has been termed as the Bunsen burner of the 21 st century. In many respects, this technique is superior to classical heating because it reduces the reaction time and provides higher yields and purity (1)(2)(3)(4)(5).…”

In this work, 15 different coumarin hydrazides were successfully synthesized and screened for their antioxidant and antilipase activities. To do this, firstly, salicylaldehyde derivatives and Meldrum's Acid were reacted in absolute ethanol with catalytic amount of pyridine to obtain coumarin-3-carboxylic acid derivatives (1a-e). Then, these compounds were treated with 1H-benzotriazole in dichloromethane by using thionyl chloride to synthesize benzotriazole derivatives (2a-e). Then, compounds 2a-e were reacted with three commercial hydrazides (nicotinic hydrazide, benzhydrazide,and phenyl acetichydrazide) in ethanol by using microwave irradiation and conventional heating procedures to obtain final products (3-5a-e). Finally, these compounds were tested for their anti-oxidant and anti-lipase activities. The structure of newly synthesized compounds was identified by IR, 1 H NMR, 13 C NMR, and elemental analysis data.
