The incorporation of a conducting polymer is expected to stabilize the microporous graphitic layers to form a conductive porous composite to increase the capacitance. Well-organized nano- and micropores are believed to facilitate rapid ion diffusion especially when the micropore size is comparable to the ionic radii in the electrolyte solution thereby greatly boosting the capacitance. The initial capacitance of ~110 F/g of the microporous carbon network was found to increase to ~224 F/g (>100% increase) after the incorporation of polyaniline in the 1 M H2SO4 aqueous electrolyte. The non-linear behavior in the charge/discharge galvanostatic curve and the appearance of additional redox peaks in the capacitance-voltage curves confirm the presence of pseudocapacitance in the microporous carbon/ polyaniline composite in addition to the electrical double layer capacitance of pristine microporous carbon. The composite material shows the capacitance retention percentage over 80% after 1000 cycles implying a promise for novel supercapacitors with long-lasting ultra-high capacitance and power density.","PeriodicalId":49315,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"58 1","pages":"87 - 93"},"PeriodicalIF":0.9,"publicationDate":"2022-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"5127737","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}

Resulting from the electrical discharge in liquid, which fills the discharge chamber, a cavity is formed in the latter with a higher compressibility than that of the liquid in the chamber. Its pulsations create the field of pressure in the discharge chamber. At present, the role of the gas-vapor cavity is studied slightly as to the formation of the field of pressure in the discharge chamber with a deformable wall. Its definition is the aim of this work. The research is based on the earlier developed mathematical model of the electric discharge in water, which is supplemented in this work with correlations that significantly enhance the calculation precision of the discharge channel resistance and the energy released in it. It was determined that the pulsations of the gas-vapor cavity ensure pressure oscillations in it in a counter-phase with an average pressure in the liquid. They decay slowly in the discharge chamber with rigid walls, whereas the presence of the deformable wall makes the decay of the pressure oscillation to be rapid. In the mathematical model developed earlier, a change in the plasma optical transparency and its substantial effect on the pressure in the cavity as well as the pressure field in the liquid were taken into account.","PeriodicalId":49315,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"58 1","pages":"63 - 74"},"PeriodicalIF":0.9,"publicationDate":"2022-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"5127169","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}

Among various methods for producing these composites, cold roll bonding (CRB) is considered to be more efficient and more cost-effective than other bonding processes. Nowadays, Al-Cu layer composite bonds are favorable in different industries due to their low price, well conductibility, high corrosion resistance, high deformation, and good electrical conduction. This review paper deals with the investigations of the Al-Cu cold rolling process, of the bonding mechanism of metallic layers during CRB, and of the effect of the roll bond strength parameters such as initial thickness, for one. Roll bonding has three levels: (1) physical touch; (2) activating surfaces in touch; (3) interaction between bonding metals. CRB is supposed to be an in-plane strain, and the normal stress distributed on the top and bottom rollers is homogeneous. Annealing before and after rolling, the direction and speed of rolling, the amount of thickness reduction, and the lubrication conditions on the Al–Cu bond through the roll bonding process were studied. The effect of different annealing conditions on the produced intermetallic compounds at the Al–Cu rolling bond interface and the growth of the intermetallic phases and their impact on the CRB parameters was examined. The thickness of intermetallic compounds, thickness reduction under the rolling process, the rolling speed, the annealing temperature, and time affected the bond strength. The effect of the rolling speed on the bond strength depends on the touching time between the sheets during rolling, which means that the touching time between two surfaces of Al and Cu sheets reduces at higher rolling speeds. As a result, the chance for proper bonding is lost, and, therefore, the bond strength is decreased.","PeriodicalId":49315,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"58 1","pages":"41 - 50"},"PeriodicalIF":0.9,"publicationDate":"2022-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"5127181","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 morphological analyses show two different nanostructures of hexagonal nanorods and hexagonal nanosheets which are attributed to pure ZnO and Al:ZnO, respectively. Moreover, the average size and the vertical orientation of the obtained nanorods and nanosheets depend on the used synthesis methods. Furthermore, the UV-Vis analyses performed on the obtained films revealed transmittance over 70% in the UV-Vis region. In fact, the electrodeposition method allows depositing a ZnO film with a transparence higher than 13% compared to that obtained via SILAR method.
