Description: Several factors propel the transition from a fossil based to a bio-based economy, such as the depletion of non-renewable resources or the increasing need to address environmental issues. The development of bio-products from agricultural residues has a great potential, although significant improvements are still required. Almost all raw materials used for the production of plastics could be obtained from natural resources from a chemical and biothechnological point of view. The production of bio-products is not an easy task, as not all the processes are commercially feasible and/or efficient, and products obtained often possess insufficient purity or a high price. Billions of tons of biomass waste and food industry residues and by-products, also known as biowastes, are generated worldwide, which could be considered as one of the most abundant, cheap, and renewable resources available. This webinar would focus on highlighting latest research on the area of bioplastic materials, especially those rich in protein, which could be used for several applications.

Description: According to the patent landscape and the rubber industries in Thailand, natural rubber (NR) is becoming one of the most sustainable materials in the concepts of automotive tires and transportation, medical electrode and soft robotics. Thus, we are producing applications relating to the recycle of tires and belt wastes, bio-thermoplastic elastomer, electroactive drug release, self-healing material and sensor monitoring of soft robotics. For the motion sensor, unmodified-NR and modified-NR composites filled with carbon-based fillers were prepared in order to examine the effect of non-rubber component and polarity in rubber matrix to the sensor properties. The relative resistances during extension were determined under static (stepwise) and dynamic (cycling) deformation of the composites. It was found that ENR-CNT/CB exhibited mechanical properties superior to NR-CNT/CB and IR-CNT/CB. This is mainly attributed to the chemical linkages of C-O-C covalent bonding among polar functional groups on ENR molecules and CNT/CB surfaces. This helps also the recovery of resistivity to the original value after 20 extension cycles. After 10,000 cycles, the resistivity had changed by only 2 orders of magnitude. Thus, ENR-CNT/CB composites can serve in sensors for health monitoring, motion sensors, and other related products, being cost-effective and easy-to-process materials.

Description: The use of Silane Coupling Agent(s) is quite critical to the rubber compounds containing silica. Though the trend of using silica in various elastomer-recipes has been on the rise during the recent past because of the multiple advantages which include, but are not limited to, performance as well as service life of the finished product, green (environment-friendly) products, low rolling resistance (in case of tyres production) etc. The use of silica in an elastomer recipe, however, is coupled with various issues like the formation of agglomerates & consequently the stress-concentrated areas, adsorption of cure accelerators on silica surface, disturbance in the crosslink density of the vulcanizate etc. All these cons can be overcome by using SCAs in the elastomer recipe based on silica. This webinar aims to discuss the usage of SCA in a silica based recipe in order to achieve the said properties enhancement. A comparative study, based on the practical trials, will also be shared as on what practically happens if we do not use SCA in a silica based recipe. Lastly, a case study will also be presented.

Description: Natural Rubber is mostly used in blend with other general-purpose as well as specialty elastomers for various applications including Tyres, Footwear, Belting, Waterproof Clothing etc. In most of the cases the Mooney Viscosity of synthetic elastomers is far lower than natural rubber because of the inherent nervy characteristics of the latter. This is because of the high molecular weight & dense entanglements of the molecular chains of natural rubber. This difference in the mooney viscosity of natural rubber & the compatible synthetic elastomers causes difficulties in proper dispersion as well as distribution of the reinforcing fillers & other compounding ingredients in the two phases. In order to bridge the gap between the mooney viscosity of the two elastomers phases, the ingredient used is termed as “Peptizer”. This webinar is aimed to highlight various types of peptizers, their effectiveness, mode of action etc. The whole discussion is based on the practical data.

Description: Bioplastics have become a potential alternative to the use of plastics. More specifically, they will contribute to reducing the high accumulation of the latter, which is caused by their low biodegradability. In addition, these bioplastics can be obtained from waste and by-products from other industries (mainly agri-food), which not only lowers their costs but also allows them to make the most of the available resources, contributing to supporting the circular economy. In the horticultural sectors, these bioplastics provide new alternatives that reduce the use of resources. Thus, superabsorbent bioplastics can be used as a complementary water source, since they can absorb and retain a large amount of water, supplying it to crops in drought times. In this way, the water cycle is improved, by rationalizing crop irrigation. Moreover, these bioplastics can also be used for the controlled release of nutrients and can be modulated with their biodegradability. Thus, the efficiency of assimilation of these by crops is improved, avoiding the excessive use of fertilizers. However, to achieve these benefits it is important to study the processing of these materials so that they can have the required functional characteristics. Therefore, this webinar would focus on highlight the principal applications of bioplastics in horticulture, paying great attention in the novel tends and latest research in this area.
Speaker: I started the Degree in Industrial Chemical Engineering in 2013. In June 2016, I enjoyed a Research Initiation Scholarship in Technology and Design of Multicomponent Products group (TEP-229) granted by the Universidad de Sevilla, where I developed superabsorbent soy protein-based matrices with micronutrients necessary for horticulture. I continued this line of research with a Collaboration Scholarship form the Ministerio de Educación, Cultura y Deporte of Spanish Government, combining it with the Final Degree Project, so I finished the degree in June 2017 obtaining the awards from the Real Maestranza de Sevilla and Excellency Seville City Council for the best academic record. Then, I completed the Master in Food Technology and Industry and worked as Support Researcher in the TEP-229 group in the project “Development of superabsorbent and biodegradable materials processed by agro-industrial by-products”. Actually, I am hired by a fellowship for Training of University Teachers (FPU2017/01718) of the Ministry of Education and Professional Training in the Chemical Engineering department of the Universidad de Sevilla under the doctoral program “Installations and Systems for Industry” where I continue to develop my career as a researcher and as a teacher. All this has resulted in the publication of 23 articles in indexed international journals, as well as 15 book chapters and participation in 40 congresses.

Description: Lately, interest in the high strain rate behaviour of polymer matrix composites (PMCs), under a high strain rate loading, has increased continually. The main reason for this is due to the PMCs capability to provide a good balance between impact resistance, production cost, and weight. In addition, the commercial importance of PMCs means that they have been broadly used in a variety of engineering applications, such as aircraft, construction and automotive components. However, all of these applications are mainly subjected to dynamic loadings. Hence, it is crucial to investigate the high strain rate behaviours of PMCs, in order to avoid any mishaps during service. In existing works on high strain rate deformation behaviour, attention has been highly focused on polymeric virgin materials. However, the influence of the particulate fillers and continuous fibers, on rate sensitivity and dynamic behaviour, has not been considered often. Therefore, this is a great opportunity to discover the capabilities and possibilities of PMCs, to replace conventional materials; especially in high strain rate applications. In this paper, the mechanical behaviour of various polymer matrix composites at high strain rate are presented and discussed under compression configuration of split Hopkinson pressure bar apparatus with several equations for prediction purposes. The discussion also contains some essential aspects of the machine's fundamental enhancements and advantages of split Hopkinson pressure bar apparatus for polymer matrix reinforced composite specimens. Directions for future research and development were also discussed.
