In our new paper @NatureComms we use nanoporous Au membranes for bulk-suppressed and surface-sensitive Raman scattering, improving the surface-to-bulk Raman signal ratio by 10^3 - https://t.co/wXx04m6Fk1 #Raman great collaboration with @HumboldtUni @ETH @LeMansUniv #IKZ

Following the initiative of >60 German-speaking institutions including the Humboldt University we stop our activity on X, former Twitter. You can stay still in touch with us and follow our updates on our website: https://t.co/IqDl9tBHTz Thanks for following!

A picture of our Christmas party at the historical Christmas market in Friedrichshain. We were very happy to get together with colleagues and excolleagues and celebrate that the group keeps growing every year! PLD wishes you all happy holidays

[Friday Light Talks @FridayLightTalk]

Last Light Talks of the year will be given this Thursday at 5pm by our friend Rafael Nadas on Tip-Enhanced Spectroscopy! We are looking forward to discovering Rafael's work at @ufmg @fabns_nano @HumboldtUni @IRISAdlershof , and having one last drink with everybody this 2024!🎅

Meet Francesca! Francesca Ciaglia has recently joined the group to conduct the second part of her Master's thesis on linear carbon chains in SWCNTs. At PLD she will measure the samples she made at the group of Prof. Carlo Casari at @polimi Viel Erfolg!

🧠Director Prof. Stefan Hecht (@SHechtlab, @HumboldtChem, @CSMB_HU, @HumboldtUni) has become an ambassador for the science of Berlin.

Many renowned colleagues are among these #BrainsOfBerlin to inspire people to discover @BrainCityB.

This Thurday there's Light Talks! Hamish Beck from AG QOM at @HumboldtUni Physics dpt. will present the super exciting work they are doing to do cold atom experiments on the @ISS_Research @BerlinUAlliance @CSMB_HU 🚀🚀 Come join us for a nice talk and some drinks afterwards!

On Tuesday the members of PLD went on a "mystery" group event, which turned out to be a visit to the local circus. It was great fun and we now have a group mascot, a pony called Steve

Today we are taking part in the Adlershofer Forchungsforum with two posters on the anharmonicity of carbyne higher orders and PAuM for surface and thin films Raman spectroscopy. We are lucky to work in such a dynamic science and technology hub as Adlershof! @IGAFAeV @HumboldtUni

[Friday Light Talks @FridayLightTalk]

Tomorrow there will NOT be Friday Light Talks as we all we still be thinking about Nobel Laurate Alain Aspect's colloquium at 15 in the Instituts main hall! Come join us in this unique opportunity to listen to one of the quantum informations pioneers!

PLD family is growing! This week Rafael has joined our team as our new posdoc researcher. He will be the main pilot of our Porto, the TERS system that he developed as a member of the @fabns_nano team back in Brazil. Welcome to Berlin, Rafael!

[Friday Light Talks @FridayLightTalk]

This THURSDAY we are back! There will be beers, there will be pizza and there will be our great speaker Michele Segantini telling us how he set his spin-off project after his PhD within the @BMWK #Exist-Programm @technologiepark @IRISAdlershof @BerlinUAlliance @HZBde

[CSMB @CSMB_HU]

We're delighted to welcome Prof. Klaus Müllen to our institute tomorrow 🎉
A pioneer in the synthesis of graphene-like nanostructures, preparative macro- and supramolecular chemistry, his groundbreaking work is shaping the future of molecular electronics and biomedical research🧪

Strain fingerprinting of exciton valley character in 2D semiconductors is out! Our straining technique developed at Prof. Kirill Bolotin's group can reveal valley character of excitons and make momentum-indirect excitons bright in TMDs at cryogenic temps https://t.co/AMrmCTbti1

Congratulation!

@profericpop A bit like „La Ola Wave“, just much worse

A new method developed by ETH researchers can be used to determine inaccessible #SurfaceProperties. Read here what a #GoldMembrane just a few hundred atoms thick has to do with it.

Mit einem neuen Verfahren, das ETH-Forschende entwickelt haben, lassen sich unzugängliche #Oberflächeneigenschaften bestimmen. Lesen Sie hier, was eine nur wenige hundert Atome dünne #Goldmembran damit zu tun hat. 🧑‍🔬
