In the 1970s, Philips felt that the vinyl disc was coming to the end of its lifetime, because it was cumbersome, dusty and scratchy.
The Soret band should have a very short lifetime because of its strongly allowed transition and competition with fast intersystem crossing.
Most recently, this system has been used to study the reactions of Na, K, Mg, and Fe with NF3, an industrial gas with a very large global warming potential because of its atmospheric lifetime of ∼550 years, which enables it to reach the mesosphere.
TiO2 mesocrystals are often considered to be a fascinating and efficient photocatalyst because of its long lifetime carriers and effective conduction pathways.
The response to the threat from CFC's — a treaty and phaseout that is working — has been held up as a model for what humanity can do with carbon dioxide, the main emission linked to warming and the biggest threat, because of its long lifetime in the air, to drive temperatures dangerously higher.
Hence, in the presence of Fe(II), hydrogen peroxide is difficult to detect because of its short lifetime.
Muons, which resemble heavy electrons but are usually absent from matter because of its short lifetime, are present in high levels in cosmic showers.
GaN-based white light-emitting diode (LED) is the most widely used solid state light source because of its long lifetime, high energy efficiency, small size, ability to produce color light directly without filtering, and integration with other semiconductor electronic elements [1 6].
Depression is an important health issue because of its high lifetime prevalence and association with substantial disability [ 1].
Platinum II) octaethylporphine ketone (PtOEPK) was selected as the optical sensing element, because of its long lifetime, high photostability, and low photobleaching rate among other fluorescent dyes.
