Silver Sulfide Nanoclusters and the Superatom Model
2015
The superatom model of electron-shell closings has been widely used to explain the stability of noble-metal nanoclusters of few nanometers, including thiolate-protected Au and Ag nanoclusters. The presence of core sulfur atoms in silver sulfide (Ag–S) nanoclusters renders them a class of clusters with distinctive properties as compared to typical noble-metal clusters. Here, it is natural to ask whether the superatom model is still applicable for the Ag–S nanoclusters with mixed metal and nonmetal core atoms. To address this question, we applied density functional simulations to analyze a series of Ag–S nanoclusters: Ag14S(SPh)12(PPh3)8, Ag14(SC6H3F2)12(PPh3)8, Ag70S16(SPh)34(PhCO2)4(triphos…
Evolution of microstructure and related optical properties of ZnO grown by atomic layer deposition.
2013
A study of transmittance and photoluminescence spectra on the growth of oxygen-rich ultra-thin ZnO films prepared by atomic layer deposition is reported. The structural transition from an amorphous to a polycrystalline state is observed upon increasing the thickness. The unusual behavior of the energy gap with thickness reflected by optical properties is attributed to the improvement of the crystalline structure resulting from a decreasing concentration of point defects at the growth of grains. The spectra of UV and visible photoluminescence emissions correspond to transitions near the band-edge and defect-related transitions. Additional emissions were observed from band-tail states near th…
Atomic layer deposition of AlN from AlCl3 using NH3 and Ar/NH3 plasma
2018
The atomic layer deposition (ALD) of AlN from AlCl3 was investigated using a thermal process with NH3 and a plasma-enhanced (PE)ALD process with Ar/NH3 plasma. The growth was limited in the thermal process by the low reactivity of NH3, and impractically long pulses were required to reach saturation. Despite the plasma activation, the growth per cycle in the PEALD process was lower than that in the thermal process (0.4A ° vs 0.7A ° ). However, the plasma process resulted in a lower concentration of impurities in the films compared to the thermal process. Both the thermal and plasma processes yielded crystalline films; however, the degree of crystallinity was higher in the plasma process. The…

Promotions and Earnings – Gender or Merit? Evidence from Longitudinal Personnel Data
2017
This study examines the determinants of promotions, performance evaluations and earnings using unique longitudinal data from the personnel records of a large university. The study focuses on the role of gender in remuneration using, first, information on the complexity ratings of job tasks to define promotions on job ladders and, second, information on objective individual productivity. The study finds that individual research productivity was an important determinant of promotions and earnings. The results indicate that gender has no effect on the probability of being promoted, conditional on productivity, nor does it play a role in the performance evaluation of employees. Furthermore, the…
The Role of Parliament in Sustainable Development Goals: A Case Study of Southeast Asia in International Parliamentary Forums
2021
Parliament has its role in supporting Sustainable Development Goals (SDG). SDG number 16 on peace, justice, and strong institution states one indicator of a legislative institution (for “responsive, inclusive, participatory and representative”, that the Inter-Parliamentary Union (IPU) commits to achieve. However, parliament must support the government in achieving all SDG programs as stated in Agenda 2030. What is the role of parliament in this and how to achieve it? This paper aims to show that the role of parliament in SDG is beyond the traditional legislative role of legislating, budgeting and overseeing the government, but more on representing people, meaning channeling people’s voice a…
La filosofia tra eros e agape
2008
As love for lerning, philosophy is captured in the antinomic movement of eros, which aims to cancel the indigent state of desire and therefore returns negatively towards its own condition of departure. While the erotic desire of truth tends to eliminate itself and to silence the "question" of thinking, the agapic dimension of truth presents itself as the "salvation" of eros, to which poverty gives back a positive value
