Here, we investigate how to get the deposition rate estimation of the thickness and homogenous surface of a -C ﬁlm as an i-type in solar cell applications. The a -C was prepared from palmyra liquid sugar using nebulizer as a nanospray method. The thick palmyra liquid sugar was carbonized at 250 ◦ C for 2.5 hours then continued at 300 ◦ C for 2 hours to obtain high-carbon charcoal. The thickness was examined using a SEM cross section, and the amorphous phase was measured using XRD. The amorphous characteristic of a -C is conﬁrmed by broad peaks in XRD patterns. The thickness of a -C ﬁlms was found to be thinner than in a previous study that used a similar materials and methods but different equipment in the deposition process. The average thickness of a -C ﬁlms is in the range of 200 to 450 nm, followed by an increase in the deposition time of 5 to 25 s. By these value, the deposition rate estimation was obtained using extrapolation linier method from the SEM result around 11.62 nm/s. This result can be used as a reference to make various thicknesses for the i-layer in order to ﬁnd the maximum thickness that gives high efﬁciency to amorphous carbon ﬁlm.","PeriodicalId":30814,"journal":{"name":"Jurnal Penelitian Fisika dan Aplikasinya","volume":"109 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80657049","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}

Generally, TiO 2 has three primary forms of crystal structure: anatase, brookite, and rutile. Among these types of crystal structures, anatase has good properties in photocatalysts application due to its band gap value (3.20 eV) and stability. Further, there are many methods to synthesize TiO 2 , such as sol-gel, hydrothermal method, etc. Still, the copreciptation method has a suitable method because it is easy to produce, high pure product and low cost. However, many parameters control the quality of TiO 2 itself: pH, temperature, time and mechanical process. Especially for the mechanical process, no results were reported about structure identiﬁcation of TiO 2 at mixing time below 25 hours. In this research, titanium dioxide (TiO 2 ) powder has been investigated using coprecipitation method and TiCl 3 as a raw material. The TiO 2 was synthesized by mixing the time duration at 5, 10, and 25 hours in this method. Analysis using x-ray diffraction shows that all the samples have an anatase phase. Further, Rietveld reﬁnement analysis shows that mixing duration time does not signiﬁcantly affect the lattice parameters.","PeriodicalId":30814,"journal":{"name":"Jurnal Penelitian Fisika dan Aplikasinya","volume":"45 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88877598","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 them is therapy in fracture healing using the Pulsed Electromagnetic Field (PEMF) method by utilizing a magnetic ﬁeld. Fracture healing using the magnetic ﬁeld method utilizes the Helmholtz coil, which is inﬂuenced by the current and the amount of turns ﬂowing in the magnetic ﬁeld. This study conducted a literature study on fracture healing using the PEMF and the LMHFV methods. A comparison of these two methods will show different healing effects. From the studies, we can conclude which way has the most advantage in healing. A faster rehabilitation process will have an impact on reducing implant failure. In contrast, Applying the LMHFV method to bone fractures gives more signiﬁcant and faster results in bone formation in the damaged part, and the healing process is owned faster. From these two methods, it can be concluded that the LMHFV method provides a similar healing effect than the PEMF method. Applying the LMHFV and PEMF method to bone fractures gives more signiﬁcant and faster results in bone formation in the damaged part. In addition, the healing process is owned faster.","PeriodicalId":30814,"journal":{"name":"Jurnal Penelitian Fisika dan Aplikasinya","volume":"56 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82274560","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}
