In this work, the synthesis of carbon nanotubes was carried out on the sand surface with hydrophobic properties by chemical vapor deposition (CVD). The effective temperature for the synthesis of carbon nanotubes is 800 °C. Propane-butane gas mixture was u... see more

An efficient synthetic approach towards 5-arylethynyl-1,2,4-triazines via direct C-H-functionalization of 5-H-1,2,4-triazines in reaction with lithium acetylenes is reported.

The focus of this research lies on fundamental research to provide guidelines for the design of new nanocatalyst toward improvement of the performance of proton exchange membrane fuel cells (PEMFCs). To achieve this overarching goal, several specific step... see more

Regarding the restoration concept such as restorative justice, alternative dispute resolution, circle sentencing, and ishlah,  Indonesia’s Criminal Justice System is not yet familiar with this concept. Generally, the concept of restoration is not kno... see more

Law enforcement for fisheries management violations in East Flores, East Nusa Tenggara province has not been effectively implemented. It is proven in recent years, violation’s cases of fisheries management is significantly high. This study examines how lo... see more

In this work, we described the two-step synthesis of Tri-substitutedtriazoles using microwave irradiation technique with ferric chloride as catalyst. The acid catalyzed reaction between hydrazine 1 with various aromatic aldehydes (2a-d) in ethanol as a so... see more

It has been shown that the ternary condensation of oxaloacetic ester (diethyl 2-oxosuccinate), aromatic aldehydes and 3-amino-1,2,4-triazole or 5-aminotetrazole in dimethylformamide results in formation of the corresponding diethyl 7-aryl-4,7-dihydro... see more

The effects to the extractability forwards Cr3+, Cd2+, and Pb2+ ions of de-tert-butylation and functionalization with amine groups at the upper rim of p-tert-butylcalix[4]arene had been studied by applied the p-tert-butylcalix[4]arene (1), tetrahydroxycal... see more

The scientific publications devoted to chemistry of the synthetically promising bifunctional derivatives of pyrazole – esters of 4-formylepyrazole-3-carbonic acids have been generalized and systematized. A special attention has been given to description o... see more
