In the fall of 1944, I enrolled at the Hebrew University of Jerusalem. The student body numbered about 700 and the choice of faculties was somewhat limited.My hopewas to study medicine, but the plans to open a medical school were still at the drawing board stage. I therefore chose to study chemistry with biochemistry and bacteriology as minor subjects, which I thought I would need later if I we...

tm3+, yb3+ and tm3+/yb3+ doped lavo4 nanostructures were synthe-sized for the first time by using the hydrothermal method with the aid of la(ch3co2)3 as  lanthanum source in presence of oleic acid as surfactant. the products were characterized by x-ray diffraction (xrd), scanning electron microscopy (sem), transmission electron microscopy (tem), photoluminescence (pl) spectroscopy and uv–vis di...

Title of Document: FAILURE MECHANICS OF FUNCTIONAL NANOSTRUCTURES IN ADVANCED TECHNOLOGIES Zheng Jia, Doctor of Philosophy, 2014 Directed By: Associate Professor Teng Li, Department of Mechanical Engineering The past decade has seen a surge of interest in developing novel functional nanostructures to enable advanced technologies, such as flexible electronics and high performance lithium-ion bat...

The incorporation of labeled precursors into ribonucleic acid with cell-free preparations of animal tissues has been observed in a number of laboratories (l-lo). Further studies with partially purified preparations indicate that the proximate precursors are nucleoside trirather than diphosphates (24). These enzyme preparations, unlike deoxyribonucleic acid polymerase (11-13) or polynucleotide p...

The success of long polynucleotide de novo synthesis is largely dependent on the quality and purity of the oligonucleotides used. Generally, the primary product of any synthesis reaction is directly cloned, and clones with correct products have to be identified. In this study, a novel strategy has been established for removing undesired sequence variants from primary gene synthesis products. Si...

The total amount of noncoding sequences on chromosomes of contemporary organisms varies significantly from species to species. We propose a hypothesis for the origin of these noncoding sequences that assumes that (i) an approximately equal to 0.55-kilobase (kb)-long reading frame composed the primordial gene and (ii) a 20-kb-long single-stranded polynucleotide is the longest molecule (as a geno...

Several publications from this laboratory have dealt in a preliminary fashion with the preparation and properties of highly purified polynucleotide phosphorylase from Azotobacter vinelan&i (2-4). A more detailed account of this work is presented in thii paper. Although polynucleotide phosphorylase preparations can catalyze the synthesis of a variety of homopolymers (polyadenylic acid, polyuridy...
