WebDec 1, 2006 · The luminescence intensity of the NA crystal is 3 times that of pure naphthalene crystal. Naphthalene when doped with anthracene has high light output and fast principal decay constant (<30 ns). For 662 keV γ rays ( 137 Cs source), energy resolution of 18% (FWHM) has been recorded at room temperature for NA crystals … WebNaphthalene is used for the control of clothes moths. In this application, the naphthalene vapors fill the airtight container and kill the insects. No information was found on the mode of action of naphthalene in insects. … shape of array julia

Webcooled first before the naphthalene on the left side had solidifiedin order to collect the naphthalene on the right side by vapor transport (ii). At the end, the left side contained pentacene crystal and the naphthalene was completely collected on the right side (iii). A typical temperature profile is shown in Figure 2b. Some images about the ... Naphthalene is an organic compound with formula C 10H 8. It is the simplest polycyclic aromatic hydrocarbon, and is a white crystalline solid with a characteristic odor that is detectable at concentrations as low as 0.08 ppm by mass. As an aromatic hydrocarbon, naphthalene's structure consists of a fused pair of … See more In the early 1820s, two separate reports described a white solid with a pungent odor derived from the distillation of coal tar. In 1821, John Kidd cited these two disclosures and then described many of this substance's … See more A naphthalene molecule can be viewed as the fusion of a pair of benzene rings. (In organic chemistry, rings are fused if they share two or more … See more Most naphthalene is derived from coal tar. From the 1960s until the 1990s, significant amounts of naphthalene were also produced from heavy petroleum fractions during petroleum refining, but present-day production is mainly from coal tar. Approximately … See more Exposure to large amounts of naphthalene may damage or destroy red blood cells, most commonly in people with the inherited condition known as glucose-6-phosphate dehydrogenase (G6PD) deficiency See more Reactions with electrophiles In electrophilic aromatic substitution reactions, naphthalene reacts more readily than benzene.
