The YPWLC is an extension of the Young Persons' Lecture Competition (YPLC) and is organised by the IOM3 Student & Early Career Committee.
The winners of the national finals, held in countries where IOM3 has international branches or sister institutions, compete in the world final, which every year is held in a different location around the world. The first YPWLC was held in London in 2005, and since then has travelled to different locations in four continents.
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. For most finalists, it is the experience of a lifetime!

Polydopamine-based Antimicrobial Coatings: Mussel-inspired Smart and Versatile Platforms for Orthopaedic Implants
Titanium and its alloys are probably the most popular materials for orthopaedic implants. However, titanium orthopaedic implants are vulnerable to bacterial adhesion due to opportunistic pathogens and may end up with failure. In addition, the incidence of bacterial adhesion can be exacerbated by their poor integration with human tissues. Introducing bioactive coatings on their surfaces is an effective approach to improve implants’ interactions with the human body and resistance to bacteria.
Inspired by mussels, polydopamine was found to be able to adhere to almost any solid surfaces. It possesses good antimicrobial activity, and can bond a range of chemicals to achieve many purposes like facilitating the formation of bones. More interestingly, polydopamine exhibits responsive behaviours to many in vivo and in vitro stimuli, such as pH and light. Therefore, polydopamine can be utilised to design smart platforms for more effective infection prevention for the next generation of orthopaedic implants.

How do Hexagonal Materials Recrystallise?
Recrystallisation of Hexagonal alloys is extensively utilised within both industrial and research applications as a means of microstructural development and mechanical property refinement. However, the multifaceted nature of this process has meant that the mechanistic drivers for the microstructural as well as textural evolution that occurs during heating is not yet understood. Here, a range of experiments combined with computational modelling techniques have been able to highlight that the deformation imparted onto the alloy prior to recrystallisation strongly dictates its behaviour during heating.
In this study we have developed a model to correlate the deformed microstructure to the strong orientation dependent texture change that is seen in hexagonal alloys during recrystallisation. Therefore, an understanding of the relationship between deformation and recrystallisation is essential if heat assisted texture control is to be utilised as a cost-effective method for mechanical property enhancement of hexagonal alloys.

Computational methods to investigate photocatalysis in metal-organic frameworks
Metal-organic frameworks (MOFs) are an increasingly important class of compounds in modern research. MOFs are able to absorb CO2 and various other gasses leading to their applications in gas purification. However, MOFs can also be utilised as catalysts. Aromatic ligands are common in MOFs which make them exceptional candidates for photocatalysis. In order to reduce the cost and labour invested in searching for photoactive MOFs, a computational approach can be followed. DFT and TDDFT models allow excited states to be studied to determine whether certain MOFs with the associated guest molecules are viable for photocatalytic reactions. The research here aims to develop the approach in order to identify host-guest pairs which are viable for photocatalysis. The hope is to provide a novel approach for designing reusable catalysts which can be applied to a wide range of reactions.

Design of Edible bi-wax coating on nanocellulose-added bagasse paper for Green and Waste-reducing Food Packaging
To solve issues regarding wide use of plastics and food packaging contamination during recycling, my project incorporates widely available and bio-degradable materials to create a lightweight and sturdy paper packaging. It is composed of bagasse fibres with nanocellulose fibre addition and lined with an inner coating made of beeswax and carnauba wax. The research yielded positive results; with incorporated nanocellulose improving the tensile and flexural strength of the paper substrate packaging, and the bi-wax mixture inducing super hydrophobicity for food waste reduction and anti-frosting properties for longer shelf life.
Using characterization methods such as water contact angle tests, the ‘Lotus’ state was induced onto the waxed surface, causing food matter to slide easily and reducing food loss and microbial contamination. With further tuning of fabrication parameters and experimentation, the project shows promise in achieving a frozen or liquid-slurry food-safe packaging prototype that is environmentally safe and easy to recycle.

Silver Clusters: Small Material, Big Potential
Silver has been used since prehistoric times- in fact, it is one of the first five metals discovered by humans! What we commonly recognize as silver, for instance the silver in our jewelry, has all the properties of a bulk metal; it is conductive, shiny and malleable. As we look at silver on a smaller and smaller scale, its properties actually change. At nanoscale sizes, silver starts to look red or even yellow in colour. We can use these tiny molecules of silver to do a ton of interesting things, from looking at new drug therapies, to biological imaging to producing solar energy. By controlling the exact size and composition of these molecules, you can target specific cells and binding sites in the body. The goal of my research is to deeply understand this material and investigate how these really small particles can lead to big opportunities.

Integrated geophysical approach to clarify near-surface geological model in the permafrost zone
The presentation actualizes a kinematic inversion problem and the most competent electromagnetic methods combination (transient EM sounding and ultra-wideband georadar radiometry) for its solution – refining seismic data in the heterogeneous subsurface zone.
Given detailed theoretical review and empirical interconnections between analyzing parameters shows the complexing rationality. Considered examples of complexing sTEM with seismic data taken from Western and Eastern Siberia with different near-surface zone structure show the saturation forecast increase and correlation sTEM data with the well logging. Method has high horizontal resolution, but gives only averaged resistivity value vertically in particular horizon. Introducing the ultra-wideband GPR radiometry into a single set of methods allows neutralizing this problem and also expanding the studied electromagnetic parameters amount.
These arguments confirmed by the experimental realization while engineering-geological works. Recent technological breakthrough in ultra-wideband georadar radiometry allows already data quality increase in methods’ integrated use already in oil and gas fields’ areas introduction.
