The present study discusses the role of NGOs in efforts Indonesian Humanitarian Alliance for Myanmar (AKIM: Aliansi Kemanusian Indonesia Untuk Myanmar) to handle humanitarian crisis experienced by Ethnic Rohingya groups 2017. This phenomenon began draw a lot attention when AKIM was able contribute cause even though state actors and IGO attempts were blocked government. In this case, play outsid...

Fully exploiting the properties of graphene will require a method for the mass production of this remarkable material. Two main routes are possible: large-scale growth or large-scale exfoliation. Here, we demonstrate graphene dispersions with concentrations up to approximately 0.01 mg ml(-1), produced by dispersion and exfoliation of graphite in organic solvents such as N-methyl-pyrrolidone. Th...
In this study, mechanical alloying was done by a high-energy planetary ball milling technique. A mixture of NiO and MoO3 and graphite powders were used as initial materials. After milling of powder mixture with 40 wt.% additional graphite, a temperature of 400, 550 and 1000 °C for 1 h was considered for the heat treatment of powder mixture. Also, powder mixtures containing 60, 80 and 100 wt.% a...
This paper describes a method for removing oxide film from the surface of silicon wafers using an inert gas fusion impulse furnace and precise determination of bulk oxygen within the wafer. A silicon wafer was cut to about 0.35 g (6 x 13 x 2 mm) and dropped into a graphite crucible. The sample was then heated for 40 s at 1300 degrees C. The wafer's oxide film was reduced by carbon and removed a...
Due to the ever-growing importance of rechargeable lithium-ion batteries, development electrode materials and their processing techniques remains a hot topic in academia industry. Even well-developed widely utilized active present issues, such as surface reactivity, irreversible capacity first cycle, ageing. Thus, there have been many efforts modify enhance electrochemical performance resulting...
The basic chemical structure of most prostate specific membrane antigen (PSMA) inhibitors which are now in pre-clinical and clinical studies is Glu-Ureido-based peptides. Synthesis of urea-based PSMA inhibitors includes two steps: 1- isocyanate intermediate formation and 2- urea bond formation. In current methods, isocyanate is formed in liquid phase and then reacts with amine existing in liqui...
