To support governments facing AI challenges, an international group of experts from the University of Ottawa and Université de Montréal at IVADO analyzed key factors of AI implementation success and failure in the public sector to propose policy guidance for a transformative and resilient public administration in the age of AI and to better guard against the potentially negative effects and risks brought forth by this technology.

The development of drug resistance, a natural consequence of cancer progression, has become a major obstacle to effective treatment. Due to the overexpression of drug resistance-related proteins and the distinctive properties of resistant cell membranes, achieving efficient internalization of nanomedicines into these cells remains highly challenging. Surface charge engineering has proven pivotal in nanomedicine design, with electrostatic interaction–mediated membrane anchoring of nanocarriers representing a critical breakthrough for advancing drug-resistant cancer therapy.

Lithium-sulfur batteries (LSBs), with their ultrahigh theoretical energy density, environmental benefits, and cost advantages, are considered a promising next-generation energy storage technology, but their practical application has long been hampered by the polysulfide shuttle effect and sluggish redox kinetics. To overcome these challenges, researchers from Nanjing University of Science and Technology, led by Prof. Gaoran Li, have developed an undercoordinated chromium single-atom catalyst (CrN₃) that precisely tunes the local coordination environment to accelerate sulfur redox reactions. Compared with the conventional CrN₄ structure, the CrN₃ motif optimizes 3d orbital electronic states and activates in-plane orbital interactions with sulfur species, enabling balanced polysulfide adsorption and reduced conversion barriers. Supported by theoretical modeling, advanced characterization, and electrochemical validation, the CrN₃ catalyst endows LSBs with high sulfur utilization, long cycling stability over 1000 cycles, and excellent rate performance, while maintaining high capacity under practical conditions of high sulfur loading and lean electrolyte. This work highlights undercoordination engineering as a powerful approach for advancing sulfur electrocatalysts and accelerating the practical implementation of LSBs.

Cobalt-free LiNiO₂ (LNO) is considered a promising cathode for its high energy density and cost-effectiveness. However, its structural instability under deep delithiation severely limits practical application in next-generation lithium-ion batteries (LIBs). Microstructure engineering enhances structural stability through precisely controlled lattice modulation strategies, particularly via high-valence element doping which effectively stabilizes the crystal framework through strong bonding characteristics and charge compensation effects.

Flexible electronics is profoundly leading the wave of transformation in fields such as wearable devices, health monitoring, and intelligent robots, and material innovation is undoubtedly the core driving force behind this revolution. As a new type of material prepared by compounding liquid metals (LM) with other materials, LM thin films, with their unique properties, have become an ideal candidate in the field of flexible electronics preparation, laying a solid foundation for the vigorous development of flexible electronics technology.
