The temperature rise and fluid flow behaviour from the top to the bottom of the tool were evaluated. Also, the strain rate and dynamic viscosity variation were found near the tool pin and shoulder region. The results showed that the frictional contact heat between the shoulder surface and workpiece was responsible for the maximum heat generation. The probe area was minimum in the square tool pin geometry, which results in high heat generation due to the maximum shoulder surface contact area with the workpiece model. Furthermore, the analytical formula for calculating the heat generation on the tool shoulder/workpiece interface and the tool pin/workpiece contact region were also evaluated. The numerical modelling of heat generation was evaluated by COMSOL Multiphysics V5.3a software.","PeriodicalId":14079,"journal":{"name":"International Journal of Materials Research","volume":"20 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85666843","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}

The prominent excitation peak observed at wavelength 463 nm corresponding to excitation energy 2.68 eV was due to the 5I8 → 5G6 + 5F1 transition. The photoluminescence emission spectra revealed that the synthesized phosphors emitted in the green color region with the 5S2 + 5F4 → 5I8 transition, releasing 2.27 eV energy. The emission and excitation analyses revealed the presence of concentration quenching as the Ho3+ concentration exceeded 0.03 mol in the Ca2La8−x(SiO4)6O2:xHo3+ series. Further, photometry analysis demonstrated a color purity exceeding 94 %, which supports the candidacy of these phosphors for solid-state lighting applications.","PeriodicalId":14079,"journal":{"name":"International Journal of Materials Research","volume":"32 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90293158","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}

The surface modification of GO with trihexyltetradecyl phosphonium ampicillin ([TTP][Amp]) IL as indicated by FTIR, SEM, pH and zeta potential measurements imply in nearly five times lower MBC value compared to average MBC value of the four GO variants.

The Schottky junctions were formed at the interface region of the MCS nanorods and the NiSe2 nanoparticles, strengthening the visible-light absorption intensity and accelerating the separation of photoinduced electron–hole pairs. The resulting built-in electric field prevents the photo-excited electrons from migrating back to MCS and reduces the charge carrier recombination, thus, improving the photocatalytic hydrogen production performance.

In this preliminary work, we sought to develop a molecularly imprinted polymers (MIPs)-based electrochemical sensor that could rapidly and selectively detect PIC. The electrochemical sensor performance was evaluated using differential pulse voltammetry (DPV) in a linear range between 1 and 5 mM, with a limit of detection of 0.6 mM (S/N = 3) and a limit of quantification of 1.7 mM (S/N = 10). The interference analysis was also conducted on the MIPs sensor to evaluate its ability to selectively detect PIC in the presence of other interfering molecules. Overall, the results demonstrate that this sensor has significant potential for use in the rapid and selective detection of PIC by electrochemical analysis.","PeriodicalId":14079,"journal":{"name":"International Journal of Materials Research","volume":"52 1","pages":"4214 - 4224"},"PeriodicalIF":0.8,"publicationDate":"2023-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87846407","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}

Microstructural images showed a clear interface between the fillers and matrix and no obvious shrinkage cavity was detected. The quasi-static compressive stress–strain curve of the AMSFs underwent three stages, namely linear-elastic, plateau, and then densification stages. The long plateau stage indicated that the AMSFs have excellent energy absorption capacity. The compressive strength and specific energy absorption capacity of the syntactic foam was lower when smaller particles were used and the compressive strength of bimodal AMSFs was much lower than that of monomodal AMSFs. The deformation of the AMSFs under compressive load, indicates that the distribution of the particles has an important influence on the failure mechanism of the AMSFs.","PeriodicalId":14079,"journal":{"name":"International Journal of Materials Research","volume":"5 1","pages":"4408 - 4419"},"PeriodicalIF":0.8,"publicationDate":"2023-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76122050","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}

Recent experimental information revealed a new phase equilibrium data; therefore, it is reasonable to elaborate a state-of-art thermodynamic model of the binary Sb–Te system. In this work, a new thermodynamic description is proposed based on the available experimental data. In addition, a new DSC measurement of heat and temperature of fusion of Sb2Te3 as well as ab initio calculation of Sb2Te3 were included in the experimental dataset. The homogeneity range of Sb2Te3 was modeled according to the stability of defects obtained from first-principle calculations. The morphology of the optimized phase diagram follows the latest findings, which means that the Ksi phase has replaced the delta and gamma phases. The elaborated thermodynamic parameters allow for a good reproduction of experimental data as well as for future modeling of higher-ordered systems.","PeriodicalId":14079,"journal":{"name":"International Journal of Materials Research","volume":"34 1","pages":"4287 - 4302"},"PeriodicalIF":0.8,"publicationDate":"2023-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91174226","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}
