The compound can also be synthesized by reacting iodine vapor with molten lead between 500 and 700 °C. A thin film of PbI 2 can also be prepared by depositing a film of lead sulfide PbS and exposing it to iodine vapor, by the reaction PbS + I 2 → PbI 2 + S. The sulfur is then washed with dimethyl sulfoxide. Crystallization
Short hairpin RNA. Lentiviral delivery of shRNA and the mechanism of RNA interference in mammalian cells. A short hairpin RNA or small hairpin RNA ( shRNA /Hairpin Vector) is an artificial RNA molecule with a tight hairpin turn that can be used to silence target gene expression via RNA interference (RNAi). [1] [2] Expression of shRNA in cells ...
Terminal velocity. The downward force of gravity ( Fg) equals the restraining force of drag ( Fd) plus the buoyancy. The net force on the object is zero, and the result is that the velocity of the object remains constant. Terminal velocity is the maximum speed attainable by an object as it falls through a fluid ( air is the most common example).
Puerto San Julián, also known historically as Port St. Julian, [1] is a natural harbour in Patagonia in the Santa Cruz Province of Argentina located at 49°18′S 67°43′W. In the days of sailing ships it formed a stopping point, 180 km (112 mi) south of Puerto Deseado ( Port Desire ). Nowadays Puerto San Julián is also the name of a small ...

LAX is building cores between terminals 5 and 6, at terminals 7 and at terminal B (the Tom Bradley International Terminal) at the cost of $490 million. New cores were also included in larger renovation projects at terminals 1, 2, 3 and 4.
The series tells the story of a Navy SEAL who seeks to avenge the murder of his family. It stars Chris Pratt (who also serves as an executive producer), Constance Wu, Taylor Kitsch, Riley Keough, Arlo Mertz, and Jeanne Tripplehorn . The Terminal List was released on Amazon Prime Video on July 1, 2022, to mixed reviews.
2C-I (2,5-Dimethoxy-4-iodophenethylamine) is a phenethylamine of the 2C family with psychedelic properties. It was first synthesized by Alexander Shulgin and described in his 1991 book PiHKAL ( Phenethylamines I Have Known and Loved ).
