Can we make carbon neutral fuels more efficiently? See our computational study on understanding how Cu nanoparticles could be used to catalyse CO2 to carbon neutral fuels! Thanks #RSCPoster for hosting this amazing poster comp! #RSCCat #RSCEnergy #RSCNano #RSCPhys

I just listen to this short audio clip of Tolkien explaining why Frodo and Sam didn't just catch a lift with the Eagles to Mordor to destroy the Ring. Really great explanation and made me rethink the books and the films from a different view! https://t.co/2W4WKme5Bk

@ShaziaNabi8 Thanks heaps @ShaziaNabi8 !

@Tandava_SayS Awesome @Tandava_SayS ! Look forward to talking to you!

I had a great time reading all the posters at #RSCPoster 2022! It was great to see all the amazing research being done all over the world! Thanks heaps to the organisers and the team at @RoySocChem for putting this event on!

[Geoffrey Weal @GeoffreyWeal]

@RoySocChem Thanks @RoySocChem and @KadiriMichael1 !

[Geoffrey Weal @GeoffreyWeal]

@yvonnechoo_sl @KatRWright @PhysicsMagazine Thanks!

[Geoffrey Weal @GeoffreyWeal]

@KatRWright @PhysicsMagazine Sorry I got a twitter handle wrong, @Elizabet_Hopper is the other person that I liked her poster. Still learning twitter!

[Geoffrey Weal @GeoffreyWeal]

@KatRWright @PhysicsMagazine I also like how anyone can see my poster, not necessarily just those in academia but also to my friends and family! Thanks for asking those questions @KatRWright !

[Geoffrey Weal @GeoffreyWeal]

@KatRWright @PhysicsMagazine Oh I forgot to say, I think the way this poster comp is run makes it easy for me to be apart of this event, particularly as NZ's time zone is so different to may others who will be participating in this event and interested in seeing all the posters.

[Geoffrey Weal @GeoffreyWeal]

@KatRWright Yes I have just joined twitter for this event. I am not much of a social media person, but I see how twitter is a very powerful and importantly a very positive tool for getting to learn about cool research and amazing researchers from every part of the globe!

[Geoffrey Weal @GeoffreyWeal]

@KatRWright @PhysicsMagazine This is still the case in New Zealand where at present we cannot travel to conferences as of yet, even domestically due to covid restrictions. So this event is a great way to practise those communication skills that are vital in research! 3/3

[Geoffrey Weal @GeoffreyWeal]

@KatRWright @PhysicsMagazine It is an awesome event and is great to interact in a global community in a poster competition during a time where it’s impossible to travel anywhere to present your work in person. 2/3

@KatRWright @EdGardner_ His group has created other metal nanoparticles that can contain for example 55±1, 147±3, and 309±6 atoms, so very precise numbers of atoms! The work his group is doing could be a possible step in making precisely small Cu nanoparticles! 6/6

[Geoffrey Weal @GeoffreyWeal]

@KatRWright @EdGardner_ We have collaborated with Richard Palmer of the University of Swansea (https://t.co/Tsa5vZAHej) who creates nanoparticles as very selected sizes without the need of solvents, which is really cool! 5/6

[Geoffrey Weal @GeoffreyWeal]

@KatRWright @EdGardner_ will often contain very interesting surface properties that are not seen in larger nanoparticles (in the tens of thousands) that can have surface feature more like in sheets of metal. 4/6

[Geoffrey Weal @GeoffreyWeal]

@KatRWright @EdGardner_ It is a big challenge experimentally to fine tune the size of your Cu nanoparticle to specific sizes such as those we studied in this poster. We were very interesting in the properties of Cu nanoparticle with tens to hundreds of atoms as these nanoparticles 3/6

[Geoffrey Weal @GeoffreyWeal]

@KatRWright @EdGardner_ However, I am not sure of group who are creating Cu nanoparticle of these sizes, particularly containing just tens to hundreds of Cu atoms. If anybody reading this tweet is doing work on this give me a shout out, would be fantastic to read your work and talk more with you! 2/6

[Geoffrey Weal @GeoffreyWeal]

@KatRWright @EdGardner_ Hey @KatRWright thanks for the comment! There are a few experimental groups that are looking into the catalytic properties of Cu nanoparticle for converting CO2 to carbon neutral fuels. 1/6

[Geoffrey Weal @GeoffreyWeal]

@EdGardner_ We currently have a new PhD student who will be looking to see how this competitive H2 reaction is catalysed by these Cu nanoparticles. It will be interesting to see what he finds! 5/5
