Three-Dimensional Microstructured Lattices for Oil Sensing

Abstract

Monitoring of environmental contamination including oil pollution is important to protect marine ecosystems. A wide range of sensors are utilized in petroleum industry to measure various parameters such as viscosity, pressure, and flow. Here, we create an optical lattice mesh structure that can be used as an oil sensor integrated with optical fiber probing. The principle of operation of the sensor was based on light scattering, where the tested medium acted as a diffuser. Three different mesh-sized structures were analyzed by optical imaging, light transmission and scattering in the presence of supercut, diesel and stroke oil types within the meshes. The meshes were utilized as a medium for different types of oils and the optical diffusion and transmission were studied in the visible spectrum. Angle-resolved measurements were carried out to characterize light scattering behavior from the mesh structures. Different types of oils were identified based on the optical behavior of the lattice structure. The fabricated mesh structures can be utilized as a low-cost measurement device in oil sensing.

Fused Deposition Modeling for Unmanned Aerial Vehicles (UAVs): A Review

“…This system uses a laser beam as an energy source to build metal components by selectively melting layers of metal powder according to the CAD design [20,39] . SLM technology offers numerous merits over the other AM techniques, besides it can build complex shaped components with a high degree of accuracy and resolution [40][41][42] .…”

“…[20,39] SLM technology offers numerous merits over the other AM techniques, besides it can build complex shaped components with a high degree of accuracy and resolution. [40][41][42] Compared to SLM, EBM substitutes the laser beam with an electron beam as energy source. In EBM, an electron beam can reach a velocity of up to 8000 m s À1 while the laser beam in SLM can achieve up to 10 m s À1 .…”

Controlling the Properties of Additively Manufactured Cellular Structures Using Machine Learning Approaches

“…Metal cellular structures are high‐performance lightweight‐engineered materials, which have combination of high load‐bearing strength, high energy absorption, and unique acoustic and thermal insulation properties. These properties make them promising structures for high‐performance products such as filters, catalytic convertors, acoustic absorbers, heat exchangers, abradable seals, porous burners, biomedical implants, and oil sensors . The structures can be categorized into periodic and stochastic porous structures.…”

Tailoring selective laser melting process for titanium drug-delivering implants with releasing micro-channels

“…Additive Manufacturing (AM) is a game changer for several applications especially in the medical sector. Compared to other manufacturing processes, AM offers lower production costs for customised low-batch components, with reduced material waste and shorter leadtimes when compared to conventional machining [13][14][15]. However, perhaps the greatest advantage, is that AM enables significant design freedom, allowing the manufacture of…”
