Synthesis of Thiol Functionalized Multi-walled Carbon Nanotube/Gold Nanoparticle Composites

Interdisciplinary School of Green Energyulti-wall carbon nanotubes (MWNTs) were functionalized with 4-mercaptobenzoic acid (4-MBAc) in a polyphosphoric acid (PPA)/phosphorous pentoxide (P2O5). The resultant 4-mercaptobenzoyl-functionalized MWNT (MB-MWNT) was used to immobilize gold nanoparticles (GNPs) via the covalent Au-S bonds. The process involved that GNPs were in-situ synthesized in the presence of MB-MWNT and stabilized by trisodium citrate and sodium borohydride (NaBH4) to covalently deposit onto the surface of MB-MWNTs. The morphology of resultant MB-MWNT/GNP composite showed that GNPs are uniformly distributed on the surface of MB-MWNTs. HR-TEM and XPS studies revealed that GNPs showed well-defined crystal structure. Cyclic voltammetries of MB-MWNT and MB-MWNT/GNP composite showed that MB-MWNT/GNP composite displayed profoundly improved electrocatalytic activity over MB-MWNT.ope

PENGARUH KEPEMIMPINAN LINTAS BUDAYA EKSPATRIAT KOREA SELATAN TERHADAP KEPUASAN KERJA SERTA IMPLIKASINYA TERHADAP KINERJA KARYAWAN : Survei pada Perusahaan Tekstil PT Bintang Family Indonesia

Pengaruh globalisasi mendatangkan sebuah fenomena yaitu Masyarakat Ekonomi ASEAN (MEA) atau ASEAN Economic Community (AEC). Globalisasi memberikan pengaruh yang besar dalam dunia industri dan organisasi yaitu menghubungkan kegiatan industri dan organisasi menjadi tanpa batas. Pada perusahan yang akan penulis teliti yakni PT. Bintang Family berlokasi di Indonesia Bandung belum mampu menstabilkan pendapatan penjualan pokok Fenomena tersebut mengindikasikan masih rendahnya kinerja pegawai. Tinggi rendahnya kinerja pegawai tersebut diprediksi oleh tinggi rendahnya variabel – variabel yang mempengaruhinya, yaitu kepemimpinan lintas budaya ekspatriat dan kepuasan kerja. Penelitian ini menggunakan survey dengan jenis verificative explanation reseach terhadap 63 pegawai. Analisis dan interpretasi hasil pengolahan data menggunakan analisis deskriptif dan analisis verifikatif (Partial Least Square). Hasil analisis menunjukan bahwa variabel kepemimpinan lintas budaya ekspatriat Korea Selatan termasuk kedalam kategori tinggi sedangkan variabel kepuasan kerja serta kinerja termasuk kategori cukup serta kuat lemahnya kepemimpinan lintas budaya Korea Selatan memiliki pengaruh yang positif dan signifikan terhadap tinggi rendahnya kepuasan kerja dan kinerja karyawan. Tinggi rendahnya kepuasan kerja memiliki pengaruh positif dan signifikan terhadap tinggi rendahnya kinerja karyawan.;--The influence of globalization brings a phenomenon of the ASEAN Economic Community (MEA) or ASEAN Economic Community (AEC). Globalization has a great influence in the industrial and organizational world of connecting industrial and organizational activities with no limits. At the company to be the author thoroughly ie PT. Bintang Family located in Indonesia Bandung has not been able to stabilize the sales revenue of the principal The phenomenon indicates the low performance of employees. The high level of employee performance is predicted by the high and low variables that influence it, namely the cross-cultural leadership of expatriates and job satisfaction. This research uses survey with verificative explanation reseach type to 63 employees. Analysis and interpretation of data processing using descriptive analysis and verifikatif analysis (Partial Least Square). The results of the analysis showed that cross-cultural expatriate leadership variables of South Korea are included in the high category while job satisfaction and performance variables including strong category and strong weakness of cross-cultural leadership of South Korea have a positive and significant influence on the high and low job satisfaction and employee performance. The high level of job satisfaction has a positive and significant impact on the high and low employee performance

A Three-Decade Decline in the Homeownership Gender Gap: What Drove the Change, and Where Do We Go from Here?

Over the past 30 years, women have made tremendous gains in closing both the income and the education gaps between them and men, and growth in their homeownership rates has become an important manifestation of these trends. In 1990, there were 15.7 million female-headed homeowner households. By 2019, that number had reached 39.2 million. In contrast, the number of male-headed homeowner households decreased from 44.4 million to 43.1 million.In this report, we examine homeownership by the gender of the household head and how it has changed over the past three decades. Our analysis explores factors narrowing the homeownership gender gap, overall and by race and ethnicity. This narrowing can be attributed mostly to gains in household income, followed closely by the fact that more married women are head of household
