Lovis 2001 – An Advanced Rolling & Falling Ball Viscometer

Mar 17 2025 - The updated article shifts its focus from a broad, curiosity-driven discussion to a more technical and structured exploration of carbon nanotubes (CNTs). It removes historical context and speculative applications, such as space elevators, and instead delves deeper into the atomic structure of CNTs, explaining chirality, chiral vectors, and different structural models. The properties section is significantly expanded, providing precise data on tensile strength, thermal and electrical conductivity, and flexibility, making it more relevant for research-oriented readers. While the previous version explored potential uses in various industries, the new article prioritizes the fundamental science behind CNTs.

What is a Carbon Nanotube? Structure and Properties

Mar 6 2025 - The updated article shifts focus from a broad historical overview to a more structured, technical explanation of semiconductor properties and functionality. Instead of emphasizing the history of semiconductor discovery, the new version prioritizes how semiconductors work, their key properties, and their applications in modern electronics. The revised version explains band theory, doping, and charge carrier behavior in greater detail, offering a stronger scientific foundation. This replaces the previous version’s generalized historical introduction with a more structured technical approach. The new version clearly defines conductivity, doping types, and how semiconductors toggle between insulating and conducting states, providing a deeper look at semiconductor behavior. CTAs and a video have been added to encourage further exploration of semiconductor applications.
