Ammonia Cycling And Emerging Particulate Matter Pollutants Under Arable Land-Use Management: A Modelling Approach, Vivien Pohl
Ammonia Cycling And Emerging Particulate Matter Pollutants Under Arable Land-Use Management: A Modelling Approach, Vivien Pohl
Doctoral
Air quality monitoring in Ireland is under the jurisdiction of the Environmental Protection Agency in compliance with the Gothenburg Protocol, EU/national legislation, and the National Clean Air Strategy. Particulate Matter (PM) has been acknowledged as a key atmospheric pollutant, with serious public health impacts and no safe threshold of exposure in place to-date. Ammonia (NH3) emissions are linked to the secondary production of PM through atmospheric reactions occurring with acidic atmospheric components such as sulfuric acid, nitric acid, and hydrochloric acid. These reactions result in the formation of ammonium sulfate, ammonium nitrate and ammonium chloride, among others. More than 95% …
Understanding The Potential Of Plasma Activated Liquids For Biomedical Applications, Evanthia Tsoukou
Understanding The Potential Of Plasma Activated Liquids For Biomedical Applications, Evanthia Tsoukou
Doctoral
Atmospheric cold plasma has evolved as a new technology for applications used in biomedicine, agriculture and food industry. Recently, treatment of liquids using various atmospheric pressure plasmas has attracted much attention owing to multiple practical applications such as water purification, surface cleaning and decontamination with impact in dentistry, wound healing and sterilisation, or cancer therapy. The over-arching aim of this study is to build a better understanding of the parameters which govern the liquid chemistry generated in a liquid exposed to cold plasma and how these translate into biological effects on pro- and eu-karyotic organisms. The objective was to investigate …
Formulation And In Vitro Characterisation Of Fungal Chitosan Nanoparticles Coated With Zein For Improved Oral Delivery Of Selenoamino Acids, Giuliana Vozza
Formulation And In Vitro Characterisation Of Fungal Chitosan Nanoparticles Coated With Zein For Improved Oral Delivery Of Selenoamino Acids, Giuliana Vozza
Doctoral
Selenium (Se) is an essential micronutrient in both human and animal nutrition that exists in a wide array of different forms, both organic and inorganic. Selenoamino acids (SeAAs), such as selenocystine (SeCys2), selenomethionine (SeMet), and methylselenocysteine (MSC) are organic species with reported health benefits of cancer prevention, increased fertility and improved immunological status. However, supplementation of SeAAs can be challenging, due to their reported narrow therapeutic range of indices, low bioavailability and increased susceptibility to oxidation. To address this, SeAAs were encapsulated into nanoparticles (NPs) to lower their toxicity profiles in comparison to their native form, in addition to offering …
Cold Plasma Treatment Of Biodegradable Films And Smart Packaging, Shashi Pankaj
Cold Plasma Treatment Of Biodegradable Films And Smart Packaging, Shashi Pankaj
Doctoral
Cold plasma is an emerging technology offering many potential applications for food packaging. While it was originally developed to increase the surface energy of polymers, enhancing their adhesion and printability, it has recently emerged as a powerful tool for surface sterilisation of both food and food packaging materials. The food packaging industry is still dominated by petroleum derived polymers but in the past few decades there has been significant interest in the development of environment friendly, biodegradable green polymers. In this study, the interaction and effects of cold plasma with biopolymer based packaging materials (polylactic acid, zein, sodium caseinate, starch, …

Valorisation Of The Cider And Brewing Industry By-Products As Nutraceutical Ingredients, Sofia Reis
Valorisation Of The Cider And Brewing Industry By-Products As Nutraceutical Ingredients, Sofia Reis
Doctoral
By-products from the cider and brewing industries, including apple pomace (AP) and brewer’s spent grain (BSG) respectively, constitute major environmental problems due to the large quantities produced every year. They are sources of valuable compounds such as protein, fibre, essential fatty acids, phenolic compounds and minerals, some of them with antioxidant and prebiotic properties. Their high nutritional value leads to their potential use as human food products and several applications have been considered recently. The aims of this work include i) the nutritional and compositional characterisation of AP, BSG and final extruded and baked prototypes containing these by-products and ii) …
Combination Of Natural Variability Estimation With Real Time Measurement For Mushroom Shelf Life Assessment., Leixuri Aguirre
Combination Of Natural Variability Estimation With Real Time Measurement For Mushroom Shelf Life Assessment., Leixuri Aguirre
Doctoral
The shelf life of mushrooms (Agaricus bisporus) is affected by the natural variability of the produce which influences the perishable vegetable quality. One of the main causes of this variability is non-homogeneity in the product maturity at harvest, resulting in each vegetable batch being at a different stage of senescence. The present work aims to study a new approach to improve the assessment of the shelf life of mushrooms (Agaricus bisporus) taking into account this variability. The study of variability involved the: i) study of the shelf life, quality parameters and variability of the mushrooms and modelling these experimental laboratory …
The Role Of Peroxidases In The Development Of Plants And Their Responses To Abiotic Stresses., Deborah Vicuna
The Role Of Peroxidases In The Development Of Plants And Their Responses To Abiotic Stresses., Deborah Vicuna
Doctoral
Peroxidases and its effects on plants were analysed. Peroxidases are involved in many physiological processes in plants, involving responses to biotic and abiotic stresses and the biosynthesis of lignin. Liglin is a polymer responsible for rendering the plant stronger and more rigid and also making the cell walls hydrophobic. Peroxidases are involved in the polymerization of the precursors of lignin. They are also involved in the scavenging of Reactive Oxygen Species (ROS), which are partially reduced forms of atmospheric oxygen, highly reactive, and capable of causing oxidative damage to the cell. Peroxidases can be a source of hydrogen peroxide (H2O2) …
