Abstract:
The large amount of food that is deteriorated by microbial growth and lipid oxidation reaction, causes poisoning in living beings, as well as, economic losses in the world, due to the loss of these. For which, it has been proposed to use techniques to coat different types of food, using bioactive compounds that have antioxidant and antimicrobial properties. Among these bioactive compounds are betalains. Betalains are nitrogenous pigments, soluble in water, which are composed by two large structural groups: betacyanins (provide red-violet coloration) and betaxanthins (provide yellow-orange coloration). Betalamic acid is present in these groups which is considered the structural unit, and the nature of the additional residue establishes the classification of the pigment. Betalains exhibit characteristics that are attractive to different sectors of the food, pharmaceutical, and cosmetic industries: due to its properties antioxidant, anticancer and anti-inflammatory activity. However, betalains have low stability to environmental factors; such as light, temperature, and humidity. The development of edible nano-micro encapsulation matrices is considered a suitable option to protect bioactive compounds, as in the case of betalains, and one of the most used techniques to produce this type of particles is the coaxial electrospray.This technique allows to protect active compounds in the nucleus of the polymeric matrices, nevertheless, to be able to use them as food coating to prolong their shelf life, human-friendly and environmentally friendly polymers, must be used.

Abstract:
The pitaya (Stenocereus thurberi) is a fruit from the Northwest of Mexico and its use is for human feed, mainly. This fruit has a high content of betalains, which are natural pigments with a strong antioxidant and antibacterial capacity. Betalains can be extract from the pitaya pulp, however, the pigments are unstable to environmental factors such as light, oxygen, temperature, pH, and water. Which leads to the degradation pigments and lose of the antioxidant and antibacterial capacity. A potential solution to this problem is nanoencapsulation, using biopolymers that are friendly to the environment and human beings, such as cereal proteins. The development of micro and nano-particles based on cereal proteins has been of interest for researchers due to their applications in foods, medicine, agriculture, etc. Among the most promising proteins is wheat gluten, composed mainly of gliadins and glutenins; of which, glutenins have a higher molecular weight. Currently one of the promising techniques for particle development is the electrospray technique due to its advantages over other techniques. In this investigation, the electrospray coaxial technique, has been studied to be a suitable technique to protect the betalains into a glutenin matrix with the purpose of maintain the pigments stability. The aim of this work was to study the effect of the parameters of the electrospray technique and the physicochemical properties of the solutions in obtaining core-shell particles of betalains-glutenins.

Abstract:
Due to many benefits of organic light-emitting diodes (OLEDs), and their ability to be extended to electronic products, commercial fields, transport, industrial controller, and medical field 1 the performance of OLEDs has been improved speedily over the last three decades. 2,3Therefore, this project aims to explore an efficient way to reduce the manufacturing cost of the luminescent layer material and rise its suitability. Due to the low cost, simple confession, increased manufacture efficiency, and commercial cost, the solution processing to fabricate the OLED device has become the focus of research.4 PLEDs based on traditional fluorescent materials have generally restricted external quantum efficiencies (EQEs) around 5 % because of spin statistic rules,5 which greatly limit them comprehensive application. Furthermore, by simultaneously using singlet and triplet excitons by intersystem crossing (ISC), the internal quantum efficiency (IQE) of PLED devices that include organometallic phosphors is almost 100%.6 However, the rare and expensive noble metals.

Abstract:
The presence of xenobiotics in various environments indicates a serious problem due to their persistent nature and varied toxic effects to the different organisms. Phthalates is a class of xenobiotic which has been reported as endocrine-disrupting chemicals (EDCs) that include industrial compounds with a wide range of toxicological properties. Due to diverse use of phthalates and its leaching property, it eventually concentrates into the water bodies which leads to high health risk to inhabiting organisms. Therefore, the current study was intended to elucidate the effect of Benzyl Butyl Phthalate (BBP) on the gonads of African catfish, Clarias gariepinus. The fishes were exposed to the BBP at low and high doses for 5 and 10 days.

Abstract:
Covid-19 pandemic has escalated the use of plastic waste across the globe that takes hundreds of years to de- grade and finally end up as micro plastics in soil. In this work we report recycling of one time use plastic waste bottles to white light emitting carbon dots (CDs) using a pyrolytic method. Plastic waste takes hundreds of years for natural degradation and is a major cause of environmental pollution. We address this issue by recycling plastic waste bottles to CDs. Further the fabricated CDs are characterized using UV-absorption emission spectroscopies. Using our unique recycling technique, broadband single system white light emitting CDs with broad absorption and emission bandwidth of ~ 135 nm are synthesized. These dots have potential to replace semiconductor quantum dots as active emitters in next generation artificial lighting devices.

Abstract:
Composite materials are composed of two or more materials combined at the macroscale and exhibit characteristics not depicted by any of their components. The matrix binds the reinforcement, which is the actual load-bearing part of the composite. Industrialization and technological developments in the last century have benefited human beings. But at the same time, it has been a destructive force on the planet, resulting in the utilization of resources at an unsustainable rate, enormous carbon emissions, and the addition of toxic waste [1]. It has caused a huge burden on the world ecosystem, and there is a dire need to develop materials and processes that work within the natural capacity of the ecosystem. Green composite materials have emerged as the next-generation sustainable materials, offering advantages of biodegradation, renewability, low carbon emissions, and environmental friendliness, leading to a circular economy[2]. The constituents of a green composite include a bio-based polymer matrix and natural fibers as sustainable reinforcement
