“…The HR-TEM image of PEI/YSZ nanoparticles in Fig. 9(b) shows a well-organized lattice fringe with a distance of 0.25 nm, which is consistent with the (110) crystal plane of t-ZrO2 (PDF#50-1089), indicating a tetragonal phase of ZrO2 [14,15]. SAED pattern is shown in Fig.…”

“…Unlike other methods, hydrothermal treatment provides a low temperature and high pressure, which are a special physical and chemical environment for the reaction and crystallization of precursors, and effectively accelerates the ion reaction and promotes the hydrolysis process. Thus, hydrothermal synthesis is a valuable and friendly method to prepare ZrO2 nanoparticles [15][16][17], which have low agglomeration. In addition, the particle size can be controlled in a narrow distribution range by changing hydrothermal synthesis conditions.…”

Yttria stabilized tetragonal zirconia (Y0.08Zr0.94O2, YSZ) nanopowders were successfully synthesized by microwave solvothermal method (MSM). The synthesizing temperature, holding time and mineralizer concentration were optimized. The crystallization and particle distribution of as-prepared YSZ nanopowders were identified by DSC/TG, XRD, FESEM, TEM, FTIR, DLS, and BET. The dispersion of YSZ nanopowders dried by different methods and modified by polyethyleneimine (PEI) was analyzed and discussed. The results show that the PEI modified samples have the best dispersion, and the dispersion of freeze-dried samples is better than that of traditional dried ones. The particle size of the PEI modified samples calculated from the surface area determined by BET is 15.7 nm, which is consistent with that determined by TEM (16.5 nm), but slightly smaller than that calculated by the Scherrer formula according to XRD (22.3 nm). This may be attributed to the different testing principles in these methods.

Penelitian ini bertujuan untuk mengetahui bagaimana pengaruh Leadership style, Organization culture, Organization commitmen, Employee commitment dan Work attitude mempengaruhi Employee performance yang dimediasi oleh Job satisfaction. Menggunakan teknik kuantitatif dengan jumlah sampel dari 3 perusahaan dengan total reponden yang dihasilkan sebanyak 400 responden. Analisis dilakukan dengan menggunankan teknik least square. Hasil studi menunjukan bahwa variable independent (Leadership style, Organization culture, Organization commitmen, Employee commitment dan Work attitude) berpengaruh positif dan signifikan terhadap employee performance dengan job satisfaction sebagai variabel mediasi. Untuk menciptakan performa kinerja karyawan yang baik, maka penting untuk memperhatikan bagaimana suatu perusahaan menciptakan kerja sama, dan adanya tanggung jawab yang membuat perusahaan terus berkomitmen untuk mengembangkan manajemen sumber daya manusia, terutama faktor-faktor yang berpengaruh signifikan terhadap kinerja karyawan, sehingga tujuan dari perusahan akan tercapai dengan baik serta meningkatkan kualitas kinerja karyawan.

Abstract:Mixed-matrix membranes based on amorphous and semi-crystalline polyimides with zirconium dioxide (ZrO 2 ) nanostars were synthesized. Amorphous poly(4,4 -oxydiphenylenepyromellitimide) and semi-crystalline polyimide prepared from 1,4-bis(4-aminophenoxy)benzene and 4,4'-oxydiphthalic anhydride were used. The effect of ZrO 2 nanostars on the structure and morphology of nanocomposite membranes was studied by wide-angle X-ray scattering, scanning electron microscopy, atomic force microscopy, and contact angle measurements. Thermal properties and stability were investigated by thermogravimetric analysis and differential scanning calorimetry. Transport properties of hybrid membranes containing 5 wt % ZrO 2 were tested for pervaporation of a mixture of butanol-water with 10 wt % H 2 O content. It was found that a significant amount of the ZrO 2 added to the semi-crystalline polyimide is encapsulated inside spherulites. Therefore, the beneficial influence of inorganic filler on the selectivity of mixed-matrix membrane with respect to water was hampered. Mixed-matrix membranes based on amorphous polymer demonstrated the best performance, because water molecules had higher access to inorganic particles.
