“…Besides that, the photolithography process also can be implemented in this system. The photolithography is a process of transferring pattern from reticle to photoresist film on wafer by exposing to the source of light through an optical mask . An optical mask is an opaque pattern on transparent support that is used to determine the features on the wafer .…”

Researchers interest in using fuel cells as a power source has grown because fuel cells are environmentally friendly. However, fuel cells still present challenges due to their performance and cost. This limits the commercialization of fuel cell systems, particularly in liquid fuel cells. One of the major obstacles is the Nafion membrane. The Nafion membrane is extremely expensive and causes the "fuel crossover phenomenon." Therefore, researchers have proposed a membrane-less fuel cell that eliminates the need of a membrane in the system mainly in micro fuel cells. Membrane-less fuel cell has shown an improvement on power density by approximately 12% compared with conventional type of proton electrolyte membrane fuel cell. However, there still a lack of information on system design and performance. Therefore, the main objective of this review is to present an extensive study focusing on the geometrical system design and performance of a membrane-less fuel cell system. It also presents the different types of membrane-less fuel cell systems. Lastly, it highlights the current problems and potentials to improve the performance of the system. Finally, it is observed that the cost of a membrane fuel cell can be reduced by 20% to 40% compared with the conventional type of fuel cell.

“…Porous silicon, solid silicon with voids therein, is one of the most important porous materials with a wide range of applications from batteries and fuel cells to drug delivery and diagnostics [1][2][3]. Although optoelectronics, especially light emission, has been porous silicon's primary area of interest for the last 25 years, the material has recently found its way to cosmetics, consumer care, nutrition, and food industry.…”

Porous silicon is a sponge-like structure of monocrystalline silicon which although accidentally discovered, soon became one of the most well-researched silicon structures. Its properties and applications have been the main subject of several books and more than a dozen review articles. However, a survey of porous silicon fabrication methods has not been published even though more than 20 different routes have been developed to synthesize this material. This chapter briefly discusses the properties of porous silicon, describes its fabrication methods, and introduces its applications.

“…This research investigates the possible application of the neural network to model the porous silicon fabrication processes. Here in this work, ANN model can be improved simply by providing additional training data accurately in a shorter time to reduce the cost of experimental work for any practical application.Worth to mention that it can be used for nanotechnology based photonic devices and also nanotechnology based gas sensors [9].…”

Optimum thermal annealing process operating condition for nanostructured porous silicon (nPSi) by using radial basis function neural network (RBFNN) was proposed. The nanostructured porous silicon (nPSi) layer samples prepared by electrochemical etching process (EC) of p-type silicon wafers under different operatingconditions, such as varyingetchingtime (Et), annealing temperature (AT), and annealing time (At). The electrical properties of nPSi show an enhancement with thermal treatment.Simulation result shows that the proposed model can be used in the experimental results in this operating condition with acceptable small error. This model can be used in nanotechnology based photonic devices and gas sensors.
