In this study, an AA‐imprinted poly (methacrylic acid)‐based receptor was synthesized by thermal free‐radical bulk polymerization for the detection of ascorbic acid using the methacrylic acid as monomer, ethylene glycol dimethacrylate (EGDMA) as cross‐linker, and azobisisobutyronitrile (AIBN) as initiator, in the presence of a porogenic solvent dimethyl sulfoxide (DMSO). The synthesized molecularly imprinted polymer (MIP) was used as a receptor. Immobilization of the receptor layer on IDEs provided a suitable sensor for AA detection by measuring changes in electrical parameters including inductance, capacitance, and resistance with the help of LCR meter. In the series and parallel inductance, the lowest detection limits were 0.13 and 0.001 ppm, respectively. While, for series and parallel capacitance, the lowest detection limits were 0.01548 and 1.3698 ppm, respectively. In the case of resistance, the lowest limit of detection was 0.0076 and 0.08121 ppm in series and parallel, respectively. The imprinted polymer‐based sensor showed sensitivity, selectivity, and reversibility for ascorbic acid.","PeriodicalId":22062,"journal":{"name":"Surface and Interface Analysis","volume":"238 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135476222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The influence of nitrogen gas addition on the surface characteristics of organosilicon films in hexamethyldisilazane (HMDSN) and HMDSN/nitrogen (HMDSN/N 2 ) cyclonic plasmas at atmospheric pressure was evaluated. It was found that the addition of nitrogen gas is a crucial factor affecting organosilicon film growth in the plasma cyclone in one atmosphere. SEM, AFM, and ATR‐FTIR results indicated that on adding nitrogen gas, the surface morphology became rougher, the peak corresponding to the Si–O–Si group was detected at approximately 1050 cm −1 , the degree of porosity was relatively low, and the proportion of the SiCHx group decreased. In general, the surface energies of the films deposited in the HMDSN discharge and the HMDSN/N 2 gas mixture discharge exhibited similar features. SEM and AFM evaluations showed high roughness values of 44.5 nm for the film formation in the HMDSN/N 2 gas mixture discharge, while the films grown in the HMDSN discharge exhibited a relatively flat surface with a roughness of 24.5 nm. Based on ATR‐FTIR detection, cyclonic plasma‐deposited films deposited in the HMDSN discharge obtained organic moieties, while the films generated in the HMDSN/N 2 gas mixture discharge exhibited strong Si–O–Si absorption signals. A possible nano‐organosilicon film growth that prevails in atmospheric pressure plasma deposition is proposed based on atmospheric‐pressure plasma chemistry, nitrogen gas addition, and experimental observations.","PeriodicalId":22062,"journal":{"name":"Surface and Interface Analysis","volume":"68 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136136049","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Four different silane coupling agents, namely, 3‐(tri‐methoxysilyl) propyl methacrylate (TMSPMA), n‐propyl tri‐methoxy‐silane (PTMS), 3‐(tri‐ethoxysilyl) propionitrile (TESPN), and tri‐methoxy‐(octadecyl) silane (OTMS) were taken for making chemical functionality methacrylate, short methyl, nitrile, and extended methyl group respectively. The adsorption behavior of melamine over the substrates with four functionalities was determined using quartz crystal microbalance (QCM). The adsorption kinetics and adsorption isotherms of the adsorption studies were analyzed. The initial adsorption rate depends on the hydrophobicity and roughness of the surfaces. However, the subsequent adsorption rate depends on the specific interaction. The data of equilibrium adsorbed mass at various equilibrium concentrations were fitted with the modified Brunauer–Emmett–Teller (BET) and Freundlich adsorption isotherms. The estimated model parameters were analyzed and compared with the reported parameters of the relevant systems. There is good agreement between our results and the reported results. In addition, very high adsorption with a very high binding constant was observed for the adsorption of melamine OTMS surface. On the other hand, high adsorption with an intermediate layer binding constant for the adsorption of melamine on the methacrylate surface was observed. Based on this, we propose using acrylate chemical functionality to develop molecularly imprinted polymer‐based melamine sensors.","PeriodicalId":22062,"journal":{"name":"Surface and Interface Analysis","volume":"36 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135170821","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results showed that liquid ammonia pretreatment could cause certain damage to the surface structure and disulfide bonds in keratin, which enhanced the action of protease on wool surface and catalytic hydrolysis of the cuticle. The joint treatment of liquid ammonia and protease changed the secondary structure of wool. The content of α‐helix and random crimp increased, while the content of β‐sheet decreased. In addition, the shrink resistance of wool fabric was significantly improved without obvious losses in tensile strength and elongation. The combination of liquid ammonia and protease treatments provides a potential new method for the surface modification and eco‐friendly shrink‐resistant finishing of wool and further widens the application of liquid ammonia in textile industry.","PeriodicalId":22062,"journal":{"name":"Surface and Interface Analysis","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135461996","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This phenomenon has been utilized in several methods to analyze target materials. In analytical techniques, the method used to detect secondary ions is called “secondary ion mass spectrometry (SIMS).” In contrast, “secondary ion mass spectrometry with optical emission spectrometry (SIMS‐OES)” detects photons emitted from sputtered, excited atoms. Both SIMS and OES can characterize a sample surface and perform local elemental analysis of the surface, depth profiling of elements, and detection of any atom. SIMS with high sensitivity has mainly been developed for the impurity analyses of semiconductors. However, no research has been reported on applications using SIMS‐OES or a combination of SIMS and SIMS‐OES. In this study, we prove that atomic emission can be observed via ion irradiation. In addition, we show that the composition analysis is possible using the SIMS‐OES method. Herein, impurity and composition analyses were enabled by utilizing atomic emission.

The same X‐ray photoelectron spectroscopy image data set was analyzed in all three notes. We now show an analysis of this same data set using multivariate curve resolution (MCR). MCR is a widely used exploratory data analysis method. Because of MCR's nonnegativity constraints, it has the important advantage of producing factors that look like real spectra. That is, both its scores and loadings are positive, so its results are often more interpretable than those from PCA. The requirements for preprocessing data are also, in general, lower for MCR compared with PCA. To help determine the number of factors that best describe the data set, a series of MCR models with different numbers of factors was created. Based on the chemical reasonableness of its factors, a two‐factor model was selected. Scores plots/images show the regions of the image that correspond to these two factors.","PeriodicalId":22062,"journal":{"name":"Surface and Interface Analysis","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134976018","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Firstly, six possible compounds that come from BaTiO 3 and BiCoO 3 were constructed. By calculating the different antiferromagnetic (AFM) structures of strip, columnar, and layered composite structures, it is found that the ground state of the composite structure changes to G‐type AFM structure from C‐type AFM structure of pure BiCoO 3 under the influence of BaTiO 3 . Energy band calculations show that band gaps of three composite structures are smaller than those of pure BaTiO 3 and pure BiCoO 3 . Furthermore, density of states analysis shows that the conduction band minimum (CBM) and valence band maximum (VBM) of three composite structures are mainly from the contribution of Co 3 d and O 2 p . For the characteristic that CBM and VBM of materials come from different atoms, it would reduce the recombination opportunities of electrons and holes and is conducive to the increase of photoelectric conversion efficiency under visible light irradiation. The calculation of optical properties shows that optical absorption coefficients of three composite structures are much larger than that of BaTiO 3 , especially the layered composite structure. There is a high absorption peak near 500 nm of the solar spectral irradiation maximum, which is significantly important to improve the optical energy conversion efficiency of the composite materials.
