Pressure swing adsorption method using zeolite A and X is commonly used in the oxygen separation process. Zeolite LiX is widely used especially in oxygen purification systems from air for medical needs until the purity reach >90%. In the present work the simulation studies of oxygen separation from air using zeolite LiX were investigated by pressure swing adsorption method. This simulation uses 2 beds/4 steps Skarstrom cycle which generally consists of bed pressurization, adsorption, depressurization and desorption. Several variables were studied such as the effect of pressure, cycle time, and temperature to determine the level of product purity. The simulation shows that the increase in oxygen concentration is caused by an increase in operating pressure and total cycle time to obtain maximum results. Meanwhile, large pressures can reduce the efficiency of the adsorbent. The maximum oxygen concentration that can be obtained up to 99%. However, the temperature variation has no significant change. In general, pressure plays the most significant role in oxygen purification.","PeriodicalId":8039,"journal":{"name":"Applied Mechanics and Materials","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139444845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the solutions to tapering down this trend is to create fossil-free renewable energy. Due to weather conditions, wind energy is the potential energy to achieve significant fuel savings. Flettner rotor is feasible for several container carriers with various deadweight tonnage (DWT), rotor dimensions, and efficiency results. This research conducted in the Indonesian Sea uses a parametric calculation to analyze the application of the Flettner rotor in several types of bulk and container carriers with six rotor specifications to minimize carbon emission and optimize the load. This study shows the optimal efficiency of ships after using the Flettner rotor. Flettner rotor can reduce 330.15 kg of fuel in 251,667 DWT of bulk carrier and 559,22 kg on 94,727 DWT container carrier. This study also proves the decrease of carbon emission to 288.86 kg in the bulk carrier and 488.98 kg of carbon emission from the container carrier after using the Flettner rotor. This result of efficiencies can be modified and raised according to the number of installed rotors.","PeriodicalId":8039,"journal":{"name":"Applied Mechanics and Materials","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139442355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three significant operational parameters of the spiral concentrator, namely feed rate (t/h), solid feed (wt.%), and splitter position (cm), were investigated to observe their effects on the SiO2 grade (%) and recovery of SiO2 (%) in the middlings using Design of Experiments (DOE). The raw sample was sieved to prepare the feed sample in the size range of -600+75µm, which was the suitable particle size range for the glassmaking process. The SiO2 grade (%) of each middling fraction from 33 test runs was determined from XRF analysis. The analysis determined that the feed rate and weight of the solid feed (wt.%) significantly affected the separation, while the splitter position in the investigated range (4.5-5.5cm) showed a negligible effect on the percentage and recovery of SiO2 in the middling fraction. It was observed that a maximum SiO2 grade of 94.98% was achieved at a solid feed of 25%, feed rate of 0.63 t/h, and splitter position of 5.5cm. The highest SiO2 recovery of 89.74% was achieved at the solid feed of 15%, feed rate of 0.45t/h, and splitter position of 5.0cm. A trade-off between the optimized results for SiO2 Grade (%) and recovery of SiO2 (%) responses using overlaid contour plots suggested a feed rate of 0.58 t/h of feed rate and 25 wt. % solid feed regardless of the splitter position. The customized range of parameters is expected to produce 94.51% SiO2 grade (%) and 80.11% recovery of SiO2 in the middling fraction.","PeriodicalId":8039,"journal":{"name":"Applied Mechanics and Materials","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139534900","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The efficiency of a hybrid solar power plant with integrated batteries and grid energy storage is demonstrated and evaluated in this study. This study is based on real-time testing to determine battery utilization when different electrical loads for office use are combined. The workload profile during peak hours of use, which correspond to the peak time of sunshine, is used to evaluate the system. The collected findings show that the degree of effectiveness of this hybrid power plant fulfills the power simulation. During the peak irradiation time, the maximum power is 2100 watts, whereas the needed power simulation, which is 1900 watts in this case, so the power efficiency percentage is 110.52%. It means that PV can satisfy the charged power while also supplying extra power to the battery for usage at low periods.

As a result, an artificial hip prosthesis can be implanted to prevent undesirable outcomes. Throughout the jumping, running, and walking cycles, the hip joint is the most essential load-bearing and shock-absorbing component in the lower half body. As a result, using a finite element analysis technique, this work simulates the design of an Artificial Hip Joint with holes and thickness as variables, using CoCrMo acetabular implant material. ANSYS 19.1 software with transient structural characteristics will be used to simulate providing the load with the activity of climbing stairs. According to the findings of this study, the acetabular design with a thickness of 3 mm and 5 holes is the most optimal. This is due to the design's distribution of stress, strain, and total deformation being the most ideal and having a relatively low weight with appropriate usage period and safety factor forecasts.","PeriodicalId":8039,"journal":{"name":"Applied Mechanics and Materials","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139443310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, doping techniques are vital in the silicon sector due to the need to regulate the material electrical properties. The spin on dopant (SOD) approach is an alternative method that involves spinning a solution containing dopant onto SOI wafers. This research aims to determine the impact of thermal diffusion temperature and soaking time on sheet resistance of doped SOI wafer using SOD approach. Additionally, the homogeneity of doping was studied by utilizing mapping techniques. Three inches boron-doped SOI wafers were cut and cleaned according to Radio Corporation of America (RCA) standards. N-type dopants of Filmtronics SOD P509 were deposited on SOI wafer by using a spin coater, for 40 seconds at 4,000 revolutions per minute (rpm). The thermal diffusion temperature and soaking time were set between 700°C to 1000°C for 30 to 120 minutes. After thermal diffusion, hydrofluoric acids (HF) were diluted and used to etch samples. All materials were evaluated using a four-point probe, Hall Effect and Atomic Force Microscope (AFM). The results show that when the thermal diffusion soaking time increases, sheet resistance decreases until activated dopants are saturated. When sheet resistance decreases, dopant concentration rises. Temperature and soaking time increase carrier density and surface roughness, while decreasing Hall mobility. From mapping techniques, it shows low non-uniformity value which less than 10% suggests good thermal diffusion control.","PeriodicalId":8039,"journal":{"name":"Applied Mechanics and Materials","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139443303","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
