The high-temperature oxidation behaviour of Si-bearing cobalt-base superalloys has been investigated. Isothermal oxidation tests conducted at 900, 1000, and 1150 °C indicated that silicon addition can improve oxidation resistance. Furthermore, the alloy content of tungsten can have profound impact on the oxidation behaviour; low content of tungsten can promote the formation of protective alumina at...
Maleic anhydride 1 of Antrodia camphorate, which can be isolated from Chinese herbal medicine, is achieved in which the longest linear sequence is only five steps, in 40% overall yield from commercially available succinic anhydride. The crucial antrodimides 3 and 2 can be readily transformed by the chemoselective reduction with Zn/AcOH and NaBH 4 /Ni(OAc) 2 ·4H 2 O to afford...
