The best videos will be awarded wonderful prizes and the main prize will be a trip to the EuChemS Chemistry Congress in Lisbon in 2022! Read more in our info sheet!

All details about the competition and how to participate can be found in the Rules and Regulations. For any further questions you may have, please contact Sebastian Balser. Make sure to send us your video (and the filled out submission form) before 30th of September 2021!


2019 marked the 150th anniversary of Dimitri Mendeleev’s development of the Periodic Table of Chemical Elements. That is why, the United Nations has proclaimed 2019 as the International Year of the Periodic Table of Chemical Elements (IYPT 2019). Being the best “friend” of a scientist for predicting the appearance and properties of the matter, the Periodic Table of the Elements represents one of the most significant achievements in science.
To join in this special celebration, EYCN organized the second edition of its video competition Chemistry Rediscovered in honour of the IYPT. We are proud to present you the winners below!

1st Place over 18 – Marco Carlotti

Chemistry is all around us. At any moment, wherever we are, whatever we are doing, we are always surrounded by atoms from all over the periodic table combined in countless ways to make the molecules.
On our daily basis, we are more likely to interact with molecules rather than single elements: this is because our needs – from smartphones, to food, to the very processes that happen in our cells – require a level complexity that elements alone cannot provide.
Their rarity is the reason why everyone always feels a spark of curiosity when interacting with a pure element. It is true that nowadays, thanks to chemical technologies, we have an easy access to many pure elements – like the aluminum foil in your kitchen or copper in electric wires –, yet one cannot but feel amazement when seeing a new pure element for the first time.
Maybe for this reason, finding pure elements in nature can be extremely fascinating. Unfortunately, only a handful of them can exist in such ‘native’ state, and the chances of finding one decrease as we move away, in terms of periodic table, from the noble metals like gold, platinum, and silver. But there are exceptions!
In this video I traveled to a geothermal spot among the hills of central Italy, to show how and where you can find your own elemental Sulfur, one of the few non-metals that can be found pure and not bound to any other element. But beware – as often in chemistry – it won’t smell nice! https://www.youtube.com/embed/wzZoeDHdhEo

2nd Place over 18 – Louis Godeffroy, Auriane Perrin and My-An Tran

This video aims at familiarizing the general public to the lesser known, still very useful element that is gallium. In fact, gallium was found in many electronic devices we use every day as a semiconductor dopant or as a semiconductor itself when it is bound to nitrogen to form gallium nitride. The latter is likely to replace silicon-based semiconductors in the near future due to its exceptional properties. This video also emphasizes on the impact of Mendeleev’s theory of the periodic table in the sense that most of the gallium’s properties, such as its low melting point, and even its existence (eka-aluminium) had been predicted by Mendeleev himself thanks to the periodic table. Gallium was discovered in 1875, a few years after Mendeleev’s predictions, by French chemist Paul-Emile Lecoq de Boisbaudran. As mentioned before, it has a remarkably low melting point of 29.7 °C. This enables one to mold metallic objects without being burnt. In the video, a variant of the famous mercury beating heart using the non-toxic gallium is shown. Gallium also has a few academic applications such as in Focused Ion Beam or to synthesize oxide thin films on the surface of gallium droplets. https://www.youtube.com/embed/avN67waafLY

3rd Place over 18 – Jana Čimžar, Domen Otorepec and Mark Selan

The purpose of the submitted video is to broaden horizons about the importance of chemical element carbon and to present its impacts on mankind.
Carbon nucleus 12C is formed during nuclear fusion process which occurs in stars, where enormous temperature and pressure are assured. During the fusion process two helium nuclei 4He combine to form a beryllium nucleus 8Be. Due to instability of the latter one another fusion process with helium nucleus 4He follows. Since three alpha particles are included in fusion process to form carbon nucleus 12C, the process is named triple alpha process. During fusion processes gamma rays are emitted.
Carbon is the fourth most abundant element in the universe by mass after hydrogen, helium and oxygen. It is a structural important element of essential molecules of life as it is presented in proteins, carbohydrates, lipids as also in nucleic acids, e.g. DNA.
In 1869 Russian chemist Dmitri Mendeleev designed the first periodic table, in which he classified chemical elements and predicted accurately the properties of in that time yet unknown chemical elements. Among other elements also carbon appeared in the first periodic table.
Carbon in various forms caused an enormous impact on human life in history, e.g. black gunpowder was partly composed of it, as a principal source of energy it played an important role in industrial revolution, usage for writing with graphite pencils, carbon paper was used for making copies, carbon was also included in wars because of diamond mining, discovery of fullerenes and ground breaking 2D material graphene were awarded with Nobel prizes in 1996 and 2010, discovery of
nanotubes, etc.
In the end, a practical use of carbon is demonstrated through the experiment where with dehydration of sugar (sucrose), H2SO4 and followed activation with CaCl2 activated carbon was prepared. The latter was then used as a filtration agent as it was added to a stirring yellow coloured solution KI/I2 that was afterwards filtered. Due to adsorption of iodine on activated carbon, the filtered solution resulted as purified water. https://www.youtube.com/embed/_fE4LTr2Fks

1st Place under 18 – Daniel Estrada Ramírez, Petronela Oltita Ghitoaica, Emma Juanpere Colomina and Jhasmin Edith Suarez Santalla

The main purpose of this video was to show you how to tackle with Chemistry in a different way instead of using the traditional approach. We tried to find a didactic and creative way to convey a visual and entertaining idea in order to get closer to the viewer.
Have you ever wondered about what would the elements of the periodic table be like if they were human?
We have moved thus into our High School scenario experimenting with the periodic table trying to explore how it could be like if the elements behaved like real teenagers. We have represented the most known elements and we have personified them by assigning each one a personality, taking into account their intrinsic chemical characteristics. Then, we have created a storyline for them to live together, as they do in nature, but adapted to their school background. All this was done in order to show people unconventional ways of how the elements work, because new methods to transmit the passion for chemistry can be found while innovating and using one’s imagination. https://www.youtube.com/embed/edd_LmWN7QQ

2nd Place (shared) under 18 – Emmanouil Dimitroulakis, Evangelia Galanaki, Georgios Grammatikakis, Theodoros Papatzanakis and Teacher: Ioannis Chatzidakis

The video “In your element: iodine” features physical, chemical and biological properties of the iodine element. In the first part, we demonstrate the transitions between solid and gaseous states of iodine. The purple iodine fumes as well as the shiny iodine crystals formed make this demonstration experiment really impressive.
Next, we perform a variant of “the iodine clock” reaction(s). It is a classical chemistry experiment in which the abrupt color changes make it suitable both for teaching reaction kinetics and chemistry demonstrations. We timed the color development with pouring making it more spectacular and then we decolorized the solution just to bring the color back after a few seconds!
Digging in biochemistry, we show under the microscope the characteristic coloration, shape and patterns of potato starch granules as stained with iodine/iodide solution (Lugol). Then we highlight the importance of iodine as a micronutrient in human diet and we show a small part of a titration method for determining supplemented potassium iodide in table salt.
Finally, a tiny amount of the contact explosive nitrogen triiodide is detonated (NI3). (Note: Nitrogen triiodide was synthesized and let dry by the supervisor.)
Music is excerpts from “1812 Overture” by P. I. Tchaikovsky. It was chosen because of its vibrance and rhythm and some notable parallelisms with our video: “1812 overture” was synthesized in commemoration of important Napoleonic war battles. At the same time, in 1811, iodine was serendipitously discovered during saltpeter preparation which was in need during Napoleonic wars! Moreover, NI3 was first synthesized in 1812! https://www.youtube.com/embed/PWQbvRiGfns

2nd Place (shared) under 18 – Laura Gili Camino and Tessa Forns Carrera

Life is quite complex and a living organism is composed of many different cells, which work together through a perfect regulation of multiple molecular pathways. This video shows us which chemical elements are most important for the composition of our bodies and explains their main purpose and abundance. https://www.youtube.com/embed/XdN83ESfz-8

Chemistry Rediscovered – Playing with chemical reactions

On behalf of the European Young Chemists’ Network (EYCN), the younger members division of the European Association for Chemical and Molecular Sciences (EuChemS), we are very thankful for your participation in this first edition of the European video contest – Chemistry Rediscovered. This contest intended to promote chemistry among the young high-school students from all Europe. This was achieved with the help of teachers who developed scientific projects together with their students and encouraged them to present their findings in a form of a video-experiment, together with an accurate experimental protocol. We received a total of 15 amazing videos and experimental protocols from 8 participant countries and the quality and originality of the projects exceeded all expectations for this inaugural edition. It was a pleasure to watch every single one of them!

Please find below the overall classification of this competition and the videos that won the first three places.

On earth day (April 22nd) the EYCN and RSC’s Photochimica 2020 competition came to an end.
The best photo winner is Philipp Gotico and is entitled Out of the Wasteland.

Did you know that it already takes more than one planet to absorb all our current solid wastes? There are existing efforts to reduce and recycle them, but they are often faced with the limitation of weakened material properties. Inspired by how plant roots can reinforce soil, we imagine that combining both plastic and agricultural wastes would result to better recycled materials. The scanning electron microscopy image shows how coconut fibers interact with blends of plastic and styrofoam wastes, raw from the dumpsite! These fiber-reinforced plastic composites can act as brick road alternatives, paving the way to sustainable future.

Best photo runner-up is Melanie Nutter with Glow and behold.

Could sunlight be the answer to our energy demands? Highly fluorescent organic compounds can have the potential to act as photocatalysts – using light to initiate and drive a chemical reaction. With interest in chemical processes shifting towards environmental sustainability, photochemistry is an attractive option as there is no need to heat the reaction and many organophotocatalysts absorb solar irradiation, a resource that is abundantly available in nature!

Most popular photo winner is Kyangzi Calderon Cerquera with Green lantern.

Here, Kyangzi Calderon Cerquera shows a Bodipy derivative solution under UV radiation. These derivatives have high fluorescent quantum yields around 1. Bodipy compounds could work as an antenna fragment in materials for solar cells.



This was the theme of the previous (2017) edition of Photochimica, the European photography competition for scientific photography. The submission of photographs has ended and we received 35 photos from participants from 11 countries.
