Shifting away from nuclear energy, expanding solar and wind power, generating energy from biomass, reducing energy consumption. Switzerland is committed to becoming climate-neutral by 2050. An ambitious goal, which has become more urgent than ever due to the increasingly challenging geopolitical situation. How can a sustainable and resilient energy supply for Switzerland be established over the coming years? What's the optimal way to use renewable energy sources? What new technologies are especially promising? At PSI, researchers are seeking answers to these crucial questions.
Progress of the X06DA-PXIII beamline upgrade: First light in the optics hutch
On June 7, 2023, the PXIII project team successfully shone the first light into the optics hutch at the upgraded X06DA-PXIII beamline. It is an essential first step for testing new hardware and software solutions that will be implemented at SLS2.0.

Tuning magnetoelectricity in a mixed-anisotropy antiferromagnet
Control of magnetization and electric polarization is attractive in relation to tailoring materials for data storage and devices such as sensors or antennae. In magnetoelectric materials, these degrees of freedom are closely coupled, allowing polarization to be controlled by a magnetic field, and magnetization by an electric field, but the magnitude of the effect remains a challenge in the case of single-phase magnetoelectrics for applications.

A compact gas attenuator for the SwissFEL ATHOS beamline realized using additive manufacturing
Gas attenuators are important devices providing accurate variation of photon intensity for soft X-ray beamlines. In the SwissFEL ATHOS beamline front-end the space is very limited and an innovative approach has been taken to provide attenuation of three orders of magnitude up to an energy of 1200 eV. Additive manufacturing of a differential pumping system vacuum manifold allowed a triple pumping stage to be realized in a space of less than half a meter. Measurements have shown that the response of the device is as expected from theoretical calculations.

Polymer electrolyte water electrolysis: Understanding the microstructure of a core-shell based anode catalyst layer
Reducing precious metal loading in the anodic catalyst layer (CL) is indispensable for lowering capital costs and enabling the widespread adoption of polymer electrolyte water electrolysis (PEWE). This work presents the first three-dimensional reconstruction of a TiO2-supported IrO2 based core shell catalyst layer, using high-resolution X-ray ptychographic tomography at cryogenic temperature of 90 K. The high data quality and phase sensitivity of the technique have allowed the reconstruction of all four phases namely pore space, IrO2, TiO2 support matrix and the ionomer network, the latter of which has proven to be a challenge in the past.

World Day for Cultural Diversity for Dialogue and Development
On May 21st, the World Day for Cultural Diversity for Dialogue and Development, a day initially declared by the UN General Assembly in 2002, acknowledges the value of cultures and intercultural dialogue in achieving peace and sustainable development. PSI researchers from 64 nationalities work together towards a common goal of advancing science for a better tomorrow. Today, we celebrate this cultural diversity by showcasing the favorite dishes of four PSI researchers.

Promising collaboration with ITM in the field of cancer therapy
PSI and ITM Isotope Technologies Munich SE (ITM), a leading radiopharmaceutical biotech company, have entered into a collaboration for the joint development of the production of a novel therapeutic radionuclide, terbium-161. In this collaboration, PSI and ITM will combine their respective technologies and expertise in the production of terbium-161, including clinical and commercial use in targeted radionuclide therapy for the treatment of cancer. The goal is to be able to offer cancer patients new and better treatment options.
Terbium-161 has been identified as a very promising therapeutic isotope for targeted radionuclide therapy in cancer due to its excellent physicochemical properties: The convincing therapeutic capabilities of terbium-161 have been demonstrated in various preclinical studies at PSI. The collaboration with ITM - a pioneer and major player in the field of radiopharmaceutical applications - aims to combine PSI's long-standing research with ITM's extensive knowledge to drive further innovation in radionuclide therapy.
With this collaboration, ITM expands its research and production portfolio alongside Lutetium-177 and Actinium-225, which are currently the most widely used medical radioisotopes for targeted radionuclide therapy and which ITM supplies to hospitals and pharmaceutical partners worldwide.

Deciphering the Mechanism of Crystallization of UiO-66 Metal-Organic Framework
Zirconium-containing metal-organic framework (MOF) with UiO-66 topology is an extremely versatile material, which finds applications beyond gas separation and catalysis. By means of in situ time-resolved high-resolution mass spectrometry, Zr K-edge X-ray absorption spectroscopy, magic-angle spinning nuclear magnetic resonance spectroscopy, and X-ray diffraction it is showed that the nucleation of UiO-66 occurs via a solution-mediated hydrolysis of zirconium chloroterephthalates, whose formation appears to be autocatalytic.
