A rational synthetic approach to substituted naphtho[1,8-gh]quinolines using intramolecular cyclization in the presence of potassium in the series of (naphthalen-1-yl)isoquinolines is described. The photophysical properties of the obtained compounds were ... see more

Pyrene-based compounds have a great potential as fluorescent chemosensors for various analytes including common nitro-explosives, such as 2,4,6-trinitrotoluene (TNT). Compounds having two pyrene units in one molecule, such as bispyrenylalkanes, are able t... see more

In this report, we present our results from various studies to qualitatively discriminate the common military explosives viz. RDX, TNT and HMX in their pure form at a distance of ~6.5 m in standoff mode using femtosecond (fs) filament induced breakdown sp... see more

The detection of hazardous chemicals, explosives, improvised explosive materials, energetic materials and their associated compounds for security screening, forensic applications and detection of unexploded ordnance is an active area of research. The resu... see more

This paper presents a study of initiation of detonation in explosives by the impact ofprojectiles. The shock wave produced by the impact of projectiles has been considered as thestimulus for initiation of detonation. Three types of projectiles, namely (i)... see more

The bond dissociation energy (BDE) of the weakest bonds in 33 explosives were calculated and analyzed using the B3LYP method with the 6-311++G** basis set. A comparison between BDE and the impact sensitivity H50 showed that cleavage of the weakest bo... see more

A rational approach to the synthesis of substituted naphtho[1,8-ef]perimidines based on SNH methodology and cyclization  reaction in the series of condensed azines with naphthalene substituents was presented. Photophysical properties of the obtained ... see more

The consequence of Indonesia as a state of law in accordance with Article 1 Paragraph (3) of the Constitution 1945 is that it creates legal politics which continues to develop in accordance with the dynamics of political life in the Indonesia state. Legal... see more

Underwater noise poses serious threats to marine mammals, which rely on underwater sound primarily for communication, orientation and foraging. In this study, underwater noise from dynamite fishing was analyzed to infer possible effects on local marine ma... see more
