🔋 What if an electrolyte salt could become the energy-storing material? In our new article, we show how lithium perchlorate (LiClO₄) can undergo an 8-electron reduction—unlocked through electrochemically coupled oxygen-atom transfer. ⚙️ Carbon-supported Fe nanoparticles play a double role: oxygen-transfer catalyst + conversion-type cathode material. ⚡ >50% LiClO₄ conversion ⚡ 1,150 mAh g⁻¹ capacity ⚡ 1,950 Wh kg⁻¹ (per kg of LiClO₄) It is a proof of concept—not yet a practical battery—but it opens a new route toward harvesting the largely unexplored energy of p-block oxoanions. Much inspired by discussions with Prof. Reinhard Nesper (ETH emeritus) over a decade ago. pubs.acs.org/doi/10.1021/ja…

Tin halide perovskite nanocrystals will have a bright future—once they have bright emission! ✨ ​Our new paper in Advanced Materials outlines the essential first steps to get there: ❌ Stop attributing 2D-impurity PL to the nanocrystals. ❌ Eliminate those 2D impurities via amine-free synthesis. ✅ Start de-doping to manage intrinsic p-doping. ​Read our full findings here: advanced.onlinelibrary.wiley.com/doi/10.1002/ad…

Dear Students, Postdocs, and Group Leaders, all who care for novel light-emitting materials. Your best conference of the year will take place in Halkidiki this September! This is the fifth edition. EMLEM26-Emerging Light Emitting Materials nanoge.org/EMLEM26/home General organization: @nanoGe_Conf Scientific organizers: Maryna Bodnarchuk, Maksym Kovalenko 📍Halkidiki, Greece 🗓️21-23 September 2026 📅 Key dates to remember: Oral abstract submission deadline: May 25, 2026 Poster abstract submission deadline: July 20, 2026

We just published a paper on MAPbBr3 nanoplatelets with controlled edge length that sustain dilution to the single-particle level, along with the corresponding spectroscopy. These platelets are also integrated into optical cavities, thereby exhibiting strong light-matter interaction. A highly collaborative work, so thanks to each and every group involved! @SekhTaras et al. pubs.acs.org/doi/10.1021/ac…

In this article, we present several important innovations in patterning perovksite layers, compatible with standard microfabrication methods and commonplace cleanrooms, including photolithography with water-based developers. advanced.onlinelibrary.wiley.com/doi/abs/10.100…

The fifth edition of our famous EMLEM conference this year, don't miss!

Perovskite semiconductors CsPbX3 can simply be melt-cast in a conventional chemical laboratory, yielding inexpensive and excellent X-ray detector arrays. sciencedirect.com/science/articl…

Yan B. Vogel has lead this beautiful spectroelectrochemical study on ligand-engineered films of colloidal InAs quantum dots, showing electrochemical control of the electronic doping level. pubs.acs.org/doi/full/10.10…

Solid-state electrolytes (SSE) are the cornerstone of the solid state battery. They must be included also into the positive electrode architecture. What are our current choices, pros and cons of each? We discuss that in our latest perspective in ACS Energy Letters. pubs.acs.org/doi/10.1021/ac…

A new highly relevant application of inorganic lead halide perovskites from our group, as a LIDAR sensor, leveraging their light absorption and defect-tolerant electronic properties, particularly fast photoconductivity transients. onlinelibrary.wiley.com/doi/10.1002/in…

We are excited to share our latest step toward practical solid-state batteries! The incorporation of a thin Sb interlayer has made a significant impact, enabling low-pressure Li cycling with argyrodite SSEs. Find out more: authors.elsevier.com/sd/article/S24…

8+ years of this project, with long breaks, yielding novel route to InAs QDs. Such acylpnictide precursors are scalable, inexpensive and versatile. onlinelibrary.wiley.com/doi/10.1002/hl…

Our battery folks work only on hard problems - that is all-solid-state batteries. Each such step matters to eventually devise an architecture with good interfaces, practical energy and power densities. pubs.acs.org/doi/10.1021/ac…

Our Perun team took part again this year in the Winti-SOLA relay! 🏃‍♀️⚡️ A well-earned pizza followed 🍕, and we are proud to finish mid-ranking. 🙌 Thanks to everyone for the team spirit! 💙

This paper concludes the chapter on cationic ligands for perovskite nanocrystals. or not? We will see. It also sorts diverse ligands based on how tightly and how dynamically they bind. pubs.acs.org/doi/10.1021/ja…
