Microbiologically influenced corrosion in aluminium alloys and premier techniques for comprehensive identification and characterization across diverse metal types

Journal of Chemical Technology &Biotechnology, Volume 100, Issue 6, Page 1143-1158, June 2025.
Abstract Microbiologically influenced corrosion (MIC) is acknowledged as a significant type of corrosion due to its extensive impact on metal/alloy surfaces. As MIC accounts for 20% of all corrosion instances, it is a critical factor causing service failure of engineering materials such as steel and aluminium alloy.

Influence of AP Particle Size on Burning Characteristics of HMX/AP Propellants Supplemented with Fe2O3

Propellants, Explosives, Pyrotechnics, Volume 50, Issue 6, June 2025.
ABSTRACT Nitramine propellants have attracted considerable attention in the domain of solid rockets and gun propulsion because of their energetic and smokeless features. Ammonium perchlorate (AP) is the widely used oxidizer in propellants owing to the excellent burning characteristics.

Fixed‐Time Control Lyapunov Function for Networked Non‐Linear Uncertain Systems

International Journal of Robust and Nonlinear Control, Volume 35, Issue 9, Page 3598-3609, June 2025.
ABSTRACT This paper introduces a novel tool based on Lyapunov functions, aimed at analyzing the fixed‐time property of networked non‐linear uncertain systems while incorporating a specifically designed control law. The applicability of this tool is demonstrated by addressing the fixed‐time synchronization challenge within non‐linear uncertain multi ...

Assessment of Practical Satellite Quantum Key Distribution Architectures for Current and Near‐Future Missions

International Journal of Satellite Communications and Networking, Volume 43, Issue 3, Page 164-192, May/June 2025.
ABSTRACT Quantum key distribution (QKD) allows the generation of cryptographic keys beyond the computational hardness paradigm and is befitting for secure data transmission requiring long‐term security. The communication distance of fiber‐based QKD, however, is limited to a few hundred kilometers due to the exponential scaling of signal attenuation ...

Laser Terminals on CubeSats: Developments for Telecommunications and Quantum Links

International Journal of Satellite Communications and Networking, Volume 43, Issue 3, Page 133-146, May/June 2025.
ABSTRACT Satellite‐based laser communication is an emerging technology that is finding its way from research to industry. Compared to radio frequency (RF) systems, it has a more efficient size, weight, and power budget and, furthermore, is license free.
