Design and Fabrication of Tapered Optical Fiber Related Devices
Abstract: By joining conical single-mode fibers, a Mach-Zehnder interferometer with a refractive index (RI) sensor was produced. Sensors were made directly from conical SMFs using a Vytran engine. Compared to the single-taper sensor, the dual-taper sensor turned out to be more efficient. With a 10mm gap between the two taper sites in the dual-taper sensor arrangement, the RI fluctuation was quite noticeable. The principles underlying the design and fabrication of tapered …

AR Coatings in Solar Efficiency: A Study
Abstract: In the global race toward renewable energy dominance, the focus often fixes upon the exotic materials within the photovoltaic cell: silicon type, junction structure, or emergent perovskites. Yet, the most immediate and profound efficiency gains are often secured by a layer so thin it is invisible, a film of optimized material applied directly to the glass interface: the Anti-Reflective (AR) coating. These coatings are not merely an expensive aesthetic choice; …

Characterization of Polyurethane at Multiple Scales for Erosion Mechanisms Under Sand Particle Impact
Abstract: Thin polyurethane layers have been widely used as erosion-resistant coatings on helicopter rotor blades such as UH-60 Black Hawk and Eurocopter SA 315. Published research has mainly focused on empirical studies that relate the mechanical properties such as rebound resilience and hardness of polyurethane to solid particle erosion resistance. However, polyurethane possesses phase mixing at multiple scales and thus sand particle erosion resistance depends also on the microstructure and the …

A Review on Amino Acids
Abstract: Protein is made up of amino acids, which are the building blocks of the molecule. Only 20 amino acids are involved in protein synthesis, even though more than 300 amino acids have been identified. In nature, all twenty amino acids did not appear at the same time. Rather, some of them appeared first, while others were later incorporated into the genetic code. It is vital to include them in one's …
