Introduction: In the pursuit of clean and renewable energy, scientists worldwide have long sought after efficient energy storage solutions. Superionic conductors promise clean, renewable energy — at the right temperatures. These conductors, used as solid electrolytes in batteries and fuel cells, comprise solid materials in which ions move as fast …

For decades, military personnel around the world have trained for combat using laser-based systems like the Multiple Integrated Laser Engagement System (MILES). This technology, akin to a sophisticated game of laser tag, uses lasers attached to weapons and sensors on soldiers to simulate combat scenarios and provide real-time feedback on …
