The YPWLC finalists normally gather in the city where the final is to be held ahead of time, to have the opportunity to get to know each other and exchange experiences. They also have a programme of technical, cultural and social visits based around the competition, so that they get to know something of the country they are visiting and experience its culture and industry.

The IOM3 Young Persons' World Lecture Competition has been held annually in different locations around the globe since 2005. Past events have taken place in the UK, Malaysia, Singapore, the US, Brazil, Hong Kong and Australia.

Morgan Lowther - Winner

Morgan Lowther - Winner

UK

Having studied for an MSci in Natural Sciences at the University of Cambridge, UK, Morgan returned to his Midlands roots to work at the Manufacturing Technology Centre in 2016. As part of the National Centre for Additive Manufacturing, he spent time characterising the feedstocks used for metal powder bed printers. This led to a fascination with how powder, printing parameters and post-processing alter the behaviour of additively manufactured materials. 

Now a final year PhD student at the University of Birmingham, UK, Morgan's research uses 3D printing to deliver antimicrobials from biomedical implants, hoping to tackle the increasing challenge of implant-associated infections. Engaging with science outreach since his undergraduate days, a highlight has been helping students become human 3D printers. In his spare time, Morgan is a (very) amateur baker, climber and badminton player

Head, shoulders, knees and microbes: 3D printing better implants

Over 100,000 joint replacement surgeries take place each year in the UK alone, accounting for 1 in 10 hospital admissions. But the prevalence of metallic implants belies that the human body is among the most challenging environments for materials design. Implants often fail not through mechanical means, but biologically, by failing to integrate with native tissues and being colonised by microbes. With the increasing prevalence of antimicrobial resistance predicted to kill more people than cancer by 2050, making previously simple surgeries life threatening, preventing implant-associated infection is a necessity.

Conventional approaches have relied on coatings and other secondary processing to modify implants after manufacture. However, in the past decade, advances in metal additive manufacturing (AM) have opened the possibility of radically new approaches to implant design and materials. How might AM simultaneously revolutionise the production of implants and help mitigate the threat of antimicrobial resistance?

As a result, she has spent most of her PhD investigating the mechanism whereby these materials interact with light and the implications of this on engineering the said materials for renewable energy applications. This has led to multiple publications and conference contributions. After completing her PhD, she hopes to pursue her research interests and (one day) head her own green technology company. When not disappearing into the ever-frequent rabbit holes of new research fields, she loves to look after her plant collection, play tennis, paint, play piano or violin, cook, bake, embroider, sew and host dinner parties.

Engineering photo-active materials for renewable energy generation

In a world where our lifestyle (unchanged) may result in self-destruction, the renewable generation of energy is ever more important. However, the development of renewable alternatives to fossil fuels is evolving too slowly to prevent some of the catastrophic effects of climate change. Many of these alternatives are based on limited natural resources and/or require large amounts of energy to produce or maintain reducing their positive impact on the environment. In this lecture, a promising sub-category of these alternatives is explored photo-active materials and their use in solar energy conversion. The mechanisms and applications of these materials are discussed, and their requirements and challenges explained. Layered double hydroxides a specific class of these materials that can be produced in an environmentally friendly way have shown promising results and exhibit potential for material engineering. These are used to illustrate the potential of the field and the challenges faced therein.

SSBC – Self-Regulating Suspended Biogas Collectors

The global biogas industry market is expected to double over the next decade with a value of $48.8bln (USD) by 2026. Conventional biogas capturing technologies present a number of problems such as limited access to the inside of the reactors, risk of damage to the cover that can cause complete loss of methane produced, and difficulty in retrofitting to existing open reactors. The Self-Regulating Suspended Biogas Collectors (SSBC) propose a new approach to capture gas from reactors. There are significant economic and social benefits for the Australian industry and community resulting from this new technology.

The SSBC can capture and retain produced biogas while floating on top of anaerobic lagoons or reactors. The system consists of a number of small floating biogas capturing modules that operate independently. The collectors have a system that control the internal pressures, which maintains the stability of the modules and stops them capsizing. SSBC's modular design negates the need to shut down the entire anaerobic system for maintenance. Desludging and crust removal operations of the anaerobic system have been shown to be much more accessible in contrast to current technologies. The patented SSBC method presents an opportunity for business to implement biogas energy generation with reduced maintenance costs and better production efficiency using a flexible system that can be retrofitted to current reactors.

Molecular study on formation of multi-compartment structures by self-assembly amphiphilic terpolymer with dissipative particle dynamics (DPD) simulation

Efficient drug delivery, such as micelle and vesicles, plays a crucial role in disease treatment for cancer therapeutics. Current drug delivery research is moving from single compartment to multi-compartment structure to increase the capability of taking different drugs at one time. Dissipative particle dynamics (DPD) simulation at the molecular level was carried out to build micellar structures with more than one compartment. By monitoring the arm length of self-assembled amphiphilic star terpolymer, spherical, branched and cylindrical micelles and vesicles were obtained. Worm-like multi-compartment structures, which have a high potential for the uptake of several drugs, were obtained. Furthermore, evolution of the whole formation process can be clearly obtained and easily studied. DPD simulations have saved time and effort in developing new drug delivery mechanisms, and it is believed to be a powerful tool in driving development of the drug delivery system.

Metastable phases and mechanisms in the dehydrogenation process of titanium hydride

Titanium hydride (TiH2), which is an intermediate product of titanium extraction, has great potential to be an alternative material to produce pure titanium powder. This research describes the characterisation of titanium powder after dehydrogenation using various techniques. Non-isothermal dehydrogenation up to 700°C has been carried out under a high-purity argon environment. High-temperature, in situ, x-ray diffraction and Rietveld refinement were used for characterisation. Cell parameters and phase changes that were determined through the Rietveld method proved that dehydrogenation occurs through heating. It was found that several metastable phases that shared the same crystal structures were formed during phase transformation. Lattice parameters increased under the influence of thermal expansion and reduced due to dehydrogenation. The effects of these two parameters on the phase transformation and crystal structures formed were studied. The non-isothermal dehydrogenation process had a sequence of phase transformations starting from δ-titanium to a final α-titanium phase.

Greenhouse gas management and energy efficiency in an oxygen steelmaking plant

Carbon emissions and climate change are increasingly in focus. Several studies have been carried out on strategies to reduce the amount of greenhouse gases. According to the World Steel Organisation, between January 2019 and May 2020, 148,775,000t of steel were produced worldwide, demonstrating the expressiveness of the steel industry. Management of greenhouse gases must be carried out to reduce carbon dioxide emissions.

This presentation approaches the management of greenhouse gases for an oxygen steelmaking plant, under the standards of the Brazilian GHG Protocol. According to the results, carbon dioxide emissions in the melt shop have been reduced by 92% over the years. Pig iron consumption and gas recovery are variables with the largest impact on greenhouse gas emissions.

Primary aluminium production – how the wettability of carbon anodes influences energy efficiency

In 2019, almost 64Mt of primary aluminium were produced, exceeding the 2010 indicators by 40%. Primary aluminium production requires a huge amount of electrical energy, which is the reason why world producers apply much effort to reduce specific energy consumption. Due to the serious environmental issues the world is facing today, it is vital to use energy and resources sustainably. This lecture introduces aluminium reduction technology and ways to improve the energy efficiency of this process. It highlights the phenomena observed during the anode process – one of the most important parts of aluminium electrolysis – and how the wettability of carbon anodes influences the anode process and its connection to specific energy consumption. The presentation also discusses existing and potential technical solutions to improve the interaction between carbon anodes and cryolite-alumina melt, hence the energy efficiency.
