The oxygen isotopic composition of benthic foraminiferal tests (δ18Ob) is one of the pre-eminent tools for correlating marine sediments and interpreting past terrestrial ice volume and deep-ocean temperatures. Despite the prevalence of δ18Ob applic

The organic red pigment N,N‐di(3,5‐xylyl)perylene‐3,4:9,10bis(dicarboximide) is easily vacuum deposited at ambient substrate temperatures to form ordinary looking smooth films. When subsequently annealed in vacuo between ∼160 and 220 °C, an

The experimental reactor cell designed and developed for the growth of films and crystals by closed cell physical vapor transport on the Space Shuttle Orbiter is discussed. The cell design has been proven by over 60 experiments, including 18 on two s
