Beyond the limits of human hearing, ultrasonic waves—frequencies above 20 kHz—are rapidly emerging as a powerful enabler of covert communication, secure authentication, and futuristic warfare capabilities. As vulnerabilities in traditional radio-frequency (RF) systems become increasingly apparent, ultrasonic technologies present a compelling alternative. These sound-based communications bypass electromagnetic shielding, offer precise …

From Planar to Vertical: The Evolution of NAND Flash Technology NAND flash memory is a type of non-volatile storage technology that retains data even when power is removed, making it essential to everything from smartphones and solid-state drives (SSDs) to data centers and edge devices. Unlike traditional spinning hard drives, …

We are undoubtedly living longer today than ever before, but medicine is no longer content with simply extending life—it now aims to enhance the quality of those additional years. Rather than chasing immortality, we’re focusing on extending healthspan—the years of vibrant, disease-free life.  A new generation of scientists, physicians, and …

  Over the past two decades, China has transitioned from a major arms importer to a growing global arms exporter, leveraging state-led innovation, military-industrial integration, and a flexible approach to foreign military sales. With increasing investments in indigenous defense capabilities, China is no longer just modernizing its own armed forces—it …

CubeSats have emerged as game-changers in space exploration, offering an accessible, low-cost entry point for universities, startups, and governments alike. Their standardized, modular design allows rapid development and deployment for a wide range of missions, from remote sensing and atmospheric monitoring to communications and deep-space experiments. Yet as the complexity …

The Inescapable Challenge of VLEO As the space domain becomes increasingly congested, contested, and competitive, the United States is turning its eyes to Very Low Earth Orbit (VLEO)—typically between 180 km and 450 km altitude—as the next frontier for tactical advantage. This region offers unmatched benefits: reduced latency for communications, …

Beyond Linearity: Fundamentals Reimagined Nonlinear optical (NLO) materials and devices manipulate light in ways that defy traditional physics—enabling quantum communication, photonic computing, and ultrafast sensing. Instead of behaving proportionally to incoming electromagnetic fields, these materials exhibit nonlinear responses when illuminated by intense lasers. This manifests in processes like frequency conversion …

  The Promise Unlocked For decades, silicon has served as the cornerstone of semiconductor technology, but its performance falters under extreme thermal and electrical conditions. Enter aluminum nitride (AlN)—an ultrawide-bandgap (UWBG) material with a remarkable bandgap of 6.1 eV, placing it far ahead of conventional materials like silicon (1.1 eV), …
