Crystal structure of pseudoguainolide [PDF]

open access: yesActa Crystallographica Section E Crystallographic Communications, 2015
The lactone ring in the title molecule, C15H22O3(systematic name: 3,4a,8-trimethyldodecahydroazuleno[6,5-b]furan-2,5-dione), assumes an envelope conformation with the methine C atom adjacent to the the methine C atom carrying the methyl substituent being the flap atom.

Snf2 family ATPases and DExx box helicases:differences and unifying concepts from high-resolution crystal structures [PDF]

open access: yes, 2006
Proteins with sequence similarity to the yeast Snf2 protein form a large family of ATPases that act to alter the structure of a diverse range of DNA-protein structures including chromatin. Snf2 family enzymes are related in sequence to DExx box helicases,

Complexes of Platinum(II) and Iridium(III) with Liquid Crystal and Luminescent Properties [PDF]

open access: yes, 2010
This thesis is concerned with the search for luminescent metallomesogens, a class of materials that presents the combination of two different properties, luminescence (triplet emission) and liquid crystallinity. The motivation is two-fold.

Two-dimensional photonic crystal accelerator structures

open access: yesPhysical Review Special Topics. Accelerators and Beams, 2003
Photonic crystals provide a method of confining a synchronous speed-of-light mode in an all-dielectric structure, likely a necessary feature in any optical accelerator.

The crystal structure of ruthenocene [PDF]

open access: yesActa Crystallographica, 1959
>Dicyclopentadienylruthenium, or ruthenocene, crystallizes in the orthorhombic space group Pnma with a = 7.13, b = 8.99, c = 12.81 A. There are four Ru(C/sub 5/H/sub 5/)/sub 2/ molecules per unit cell. The ruthenium atoms form approximately a face-centered lattice, and the cyclopentadienyl rings lie in an eclipsed configuration with respect to each ...
