Scanning electron microscope (SEM) images reveal that the PbS is homogenously loaded and distributed in PANI chain. Using UV-Vis optical absorbance, the optical parameters of PANI/PbSNPs were evaluated, including absorption edge (Ed), band gap (Eg), carbon cluster number (N) and Urbach energies (Eu). PbSNPs has been investigated for their impact on PANI polymer linear optical (LO) as well as nonlinear optical (NLO) characteristics including refractive index, nonlinear susceptibility, and dielectric parameter’s. When comparing the PANI/PbSNPs film to the pure PANI film, the band gap of the PANI/PbSNPs samples was found to be significantly reduced. However, the addition of PbSNPs increased the predicted amount of optical conductivity and carbon cluster number. The addition of PbSNPs to the PANI polymer improved its optical characteristics, resulting in a synthetic composite that can be used in energy applications as well as optoelectronics devices.","PeriodicalId":22032,"journal":{"name":"Surface Innovations","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43621955","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, carbon nanofiber aerogel (CNFA) modified silicon oxycarbide (CNFA/SiOC) composites were prepared following a precursor infiltration pyrolysis procedure by using three-dimensional CNFA as a skeleton. Their structures and mass densities (0.28-1.35 g cm−3) were tunable by adjusting the content of polysiloxane precursor in impregnating solution. The lightweight CNFA/SiOC composite featured with continuous conductive network and highly porous structure in SiOC matrix, resulting in high specific shielding effectiveness (up to 68.9 dB·cm3 g−1 with SETotal of 19.3 dB) due to enhanced conductance loss and multi reflection/scattering. When increasing the density, the CNFA/SiOC composite can deliver EMI shielding effectiveness as high as 27.5 dB due to the generation of defective carbon and carbon dangling bonds as well as abundant interfaces between CNFs and SiOC which induce polarization loss. Moreover, the CNFA/SiOC composite exhibits good oxidation resistance with SETotal retention of above 98% after heat treatment at 600°C for 2 h in air, which arises from the effective protection of CNFs by SiOC.","PeriodicalId":22032,"journal":{"name":"Surface Innovations","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46429545","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This technology includes high-energy mechanical treatment, HVOF in a protective atmosphere, subsequent thermomechanical and thermal treatment of ZrCuNiCoTi, cBNNi3AlSiCCoY layers in a protective atmosphere. The processing allowed to increase the adhesive strength of the surface composites, reduce their porosity and improve their functional and operational properties. Staged methods of heat treatment and plastic deformation of surface layers have been developed. These methods stabilize material structure while reducing residual stresses. On the basis of complex X-ray diffraction and electron microscopic studies, the structural parameters of surface composites were determined. It was shown that the ZrCuNiCoTi alloy is in the austenitic-martensitic state and has a nanocrystalline structure with a grain size of 80–120 nm. Meanwhile, the cBNNi3AlSiCCoY alloy consists of many intermetallic phases and inclusions and has a nanosized structure with a grain size of 100–200 nm. A microhardness study of the surface layers in ZrCuNiCoTi – cBNNi3AlSiCCoY composite showed that thermomechanical treatment increases microhardness. The experimental data were statistically processed. As a result, empirical mathematical dependences of the stress amplitude on cyclic durability were compiled. Mechanical tests included tests of NiCoTiZrHf – cBNCoMo, ZrCuNiCoTi – cBNNi3AlSiCCoY, TiNiZrHfCoCu – cBNCoNiAlY composites for multi-cycle fatigue during bending with rotation.","PeriodicalId":22032,"journal":{"name":"Surface Innovations","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2022-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41983406","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One is the small Raman scattering cross section of methanol and the other is the derivatization strategy. They were solved by coupling the catalytic strategy with a thermal purge separation and enrichment device. In this study, the quantitative analysis of methanol in alcoholic beverages was performed as methanol was catalyzed to formaldehyde. For detecting methanol in low alcoholic beverages, the acetaldehyde derivatives generated by the interaction of ethanol-catalyzed oxide acetaldehyde with 3-Methyl 2-benzothiazolinonehydrazone Hydrochlide Hydrate (MBTH) during the catalytic process will not cause large interference with the SERS signal of formaldehyde. In this case, the MBTH with higher sensitivity is selected for the derivatization operation. In the analysis of methanol in high alcoholic beverages, acetylacetonate derivatization without interaction with acetaldehyde was used to avoid the interference of acetaldehyde generated from ethanol. Based on the detection of formaldehyde in methanol standard solutions, methanol was detected in wine and sake as well as in high-alcohol beverages. Thus, a convenient and rapid method was achieved for the detection of methanol in alcoholic beverages.","PeriodicalId":22032,"journal":{"name":"Surface Innovations","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2022-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45503951","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
