SAE 1050, SAE 1053, CEN C50, ISO C50
Alloy Digest, 2023Abstract 1050, 1053, C50, C50E, and C50R are wrought medium-carbon (carbon = 0.47–0.55%) non-alloy steels that are used in the normalized, cold worked, quenched and tempered, or austempered condition. 1050, 1053, C50E, and C50R may also be flame or induction hardened, nitrided, or nitrocarburized.

Synthesis of bacterial C50 carotenoid sarcinaxanthin
Tetrahedron, 1990Abstract Alkylation of the distal double bond of geranyl acetate 8 with isoprene epoxide 5 has been carried out under anhydrous ZnCl 2 /nitromethane conditions to give a mixture of C 15 hydroxyprenylated compounds. The major diol acetate isomer 12 was dehydrated to the expected γ- cis synthon 17 which was converted into racemic ...

Fullerene C50: Sphericity takes over, not strain
Chemical Physics Letters, 2005Abstract It is commonly accepted that the most stable fullerene geometry among all possible structures built from hexagons and 12 pentagons is that with minimum strain. This implies that the most stable structure corresponds to the minimum number of adjacent pentagons. Here, we report that the fullerene C 50 and some of its endohedral derivatives do

A density functional study of C50 passivation
Chemical Physics, 2006The structural, energetic and electronic properties of D-5h C-50 before and after passivation by H and Cl are investigated using density functional theory method with GGA and LDA exchange-correlation functional. The results show that H or Cl addition can lead to structural changes and energetic stabilization.

Theoretical study on one-dimensional C50 polymers
Diamond and Related Materials, 2012Abstract Several possible one-dimensional (1D) polymers constructed from fullerene D 5h C 50 cages are investigated by means of the self-consistent field crystal orbital method based on density functional theory. In this paper we focus on their structures, stabilities, and electronic and elastic properties. It is found that several factors, such as
