TIK WORKING PAPERS on Innovation Studies
Although the impacts of greenhouse gas build-up remain uncertain, they have the potential to be very serious and possibly catastrophic. If the outcomes are serious then neither improving energy efficiency nor adaptation policies will cope with the problems of warming. Reducing climate impacts without impeding economic development will require new low or zero emissions energy carriers and associ...
متن کاملSynthetic studies on leupeptins and their analogs.
Leupeptins, fermentation products of various strains of Actinomycetes^ showed strong antiplasmin activity2) and were identified as being a mixture of two major components, leupeptin Ac-LL (acetyl-L-leucyl-L-leucyl-DL-argininal, 1) and leupeptin Pr-LL (propionyl-L-leucyl-L-leucyl-DL-argininal, 2), and their analogs containing isoleucine or valine in place of one or two leucine residues of 1 or 2...
متن کاملStudies on sintering process of synthetic hydroxyapatite.
In this study the effect of sintering process in different temperatures on microstructure and morphological properties of sintered hydroxyapatite (HAp) was investigated. HAp powder was prepared by wet precipitation method from following reagents: Ca(OH)2 + H3PO4 in an alkaline conditions. Thermal analysis (TA), X-Ray diffraction method (XRD), FT-IR spectrometry (FT-IR) and scanning electron mic...
متن کاملSynthetic studies on formamidopyrimidines related to clofarabine.
Degradation of clofarabine (3) in 0.9% saline solution at 100 degrees C afforded three degradation products which were determined to be formamidopyrimidines 4-6. Compounds 4 and 5 were assigned as C(1') anomers on the basis of one-dimensional and two-dimensional NMR experiments, whereas 6 was found to be the formamidopyrimidine lacking the sugar moiety. An improved procedure for the synthesis o...
متن کاملSynthetic studies on heterocyclic natural products.
This article reviews past and ongoing research in the author's laboratory directed toward the synthesis of natural products displaying an azaspirocyclic framework, or incorporating a medium-ring nitrogen heterocycle. New synthetic technologies were devised in order to address the synthetic problems posed by the target molecules. Thus, efforts in the area of azaspirocyclic substances have relied...
