Our latest publication, entitled "Molecular Interfacial Regulators Enable Stable Sulfide Electrolytes for High-Performance All-Solid-State Batteries," has just been accepted for publication in Advanced Energy Materials.
In this study, we report a highly effective surface-coating strategy for sulfide electrolytes that stabilizes the electrode-electrolyte interface in all-solid-state batteries. This research has been funded by SNSF under the Sinergia Funding Scheme.
Congratulations to Laras for this excellent work!

Check out our latest publication! Murad has done an amazing job with this project, where he demonstrated Pd–Cu single-atom catalysts in COFs for the Sonogashira cross-coupling reaction under batch and flow conditions, as well as the metal cooperativity on the same crystalline support. This approach also allowed us to precisely control the positions and coordination environment of metal ions. Supported by NCCR Catalysis,
In this study, we report the synthesis of a macrocyclic porous organic polymer for size and shape selective separation of organic solvents. This research has been funded by NCCR Catalysis.
Congratulations to Murad for this excellent work!

Our latest publication, in collaboration with the Choi group at Seoul National University, entitled "Mechanically Adaptive Polyrotaxane Interlayers for Low-Pressure High Energy Density Sulfide-Based All-Solid-State Batteries," has just been accepted for publication in Angewandte Chemie.
Jihoon and Leonie Braks developed mechanically adaptive interfaces enabling robust cycling stability and reliable operation under commercially relevant conditions (25°C, 0.8 MPa), even in an anode-less configuration (N/P = 0) in sulfide-based all-solid-state batteries. This work shows the potential of composite interfaces containing elastic polymers such as polyrotaxanes to mitigate challenges in operating ASSBs at commercially relevant pressures. This research has been funded by SNSF under the Sinergia Funding Scheme.
Congratulations to Leonie for this excellent work!

Check out our latest publication in Angewandte Chemie, amazing work by Patrick W. Fritz and Eylül Attar Çalıkyılmaz. In this work, we designed a new tetraoxacirculene-based porous organic polymer for gold capture from e-waste. We also showed that the resulting material can serve as a heterogeneous catalyst for the two-step annulation reaction to yield a quinoline derivative. We demonstrated that by simply changing the solvent, it is possible to realize product divergence using the same heterogeneous catalyst!
This research has been funded by NCCR Catalysis.
Congratulations to Patrick and Eylül for this excellent work!

Our latest publication, in collaboration with the Choi group at the Seoul National University, entitled "Solvation Structure Engineering of Weakly Coordinating Sulfonamide Electrolytes for 4.6 V Lithium Metal Batteries" is just accepted for publication in ACS Energy Letters.
In this study, we systematically investigated the effect of ring size (4–6) at the N-terminal to tune their steric and electronic properties of trifluoromethanesulfonamide solvents to realize enhanced contact ion pairs for the formation of an anion-derived solid-electrolyte interface (SEI) and compatibility with the NMC811 cathode.
