Low temperature deformation characteristics of yttrium single crystals

Creator:: Sokaski, Michael
Abstract:: First order prism slip in yttrium single crystals containing a total interstitial impurity content of about 200 wt ppm is almost entirely stage II deformation with a work hardening rate θ/μ of 2·10⁻ ³ . The athermal temperature is about 300°K. Below this temperature an interstitial mechanism is rate controlling...

Approaches to the synthesis of penicillin

Creator:: Furuta, Takuya
Abstract:: Several approaches to the synthesis of penicillin from 2-iminothioazolidine 50, from 2-thiothiazolidine 66 and by photocyclization of 77 and 78 were investigated. 2-Iminothiazolidine 50 was prepared from dibromoester 45 by the action of benzylamine followed by treatment of aziridine 46 with potassium or ammonium thiocyanate. Attempted introduction of a two-carbon...

Circular dichroism of amylose and glucose oligosaccharides in the vacuum ultraviolet

Creator:: Lewis, Donald George
Abstract:: The circular dichroism spectra of amylose, the maltose oligomers, cellobiose, and the cycloamyloses are measured in aqueous solution to 1640 A. Two bands are found in this region. The long wavelength band is assigned to the ether chromophores; the short wavelength band is assigned to the hydroxyls and further ether...

Intercalation on hydrocarbons in polynucleotides

Creator:: Craig, Albert Morrie
Abstract:: The binding of eleven polycyclic, aromatic hydrocarbons to the acid form of poly A has been investigated. The hydrocarbons were chosen to test a size criterion. Model building showed that some hydrocarbons could intercalate in the helix and be well protected from contact with the aqueous solvent. Experimentally it was...

X-ray structure studies of oriented phospholipid multilayers

Creator:: Lytz, Robert Keith
Abstract:: Lamellar x-ray diffraction was studied from thin films of L-α-1,2-dipalmitoyl lecithin (DPL) and a 1:1 mixture (BrDPL) of L-α-l-palmitoyl-2-(9- bromopaimitoyl) lecithin and its 10-bromo analog. The specimens had high lamellar order, with an upper bound on the mosaicity of 6 mrad (0.4°) for DPL and BrDPL. With various water contents,...

Surface effects in photoemmission from sodium

Creator:: Whitefield, Rodney Joe
Abstract:: An investigation was made of the photoelectric emission from sodium and the alteration in the emission produced by sulfur deposited onto a sodium surface. Measurements were made at the temperature of liquid nitrogen for photon energies between 2.0 ev and 4.5 ev. The sodium was investigated in the form of...
