Dependance of avalanche photodiode characteristics on active area geometry
(Institute of Electrical and Electronics Engineers (IEEE), 1995)
The work presents an analysis of avalanche photodiode (APD) with spherical p-n junction. The calculation results are given for the dependence of the avalanche multiplication and noise parameters on geometry and on the ...
Mixed dopaminergic/serotonergic properties of several 2-substituted 4-[2-(5-benzimidazole)ethyl]-1-arylpiperazines
(Wiley-VCH Verlag, 1998)
A series of substituted 4-[2-(5-benzimidazole)ethyl]-arylpiperazines was synthesized by introducing different substituents into position 2 of benzimidazole ring of 4-[2-(N,N-di-n-propylamino)ethyl]-1,2-diaminobenzenes. ...
Surface characterization of oxidized activated carbon cloth
(Elsevier, 1997)
Cellulose based activated carbon cloth has been oxidized by air, nitric acid, hydrogen peroxide and iron nitrate cristallohydrate melt treatments. Thermogravimetric analysis, selective neutralization, X-ray photoelectron ...
An efficient semisynthesis of 7-deoxypaclitaxel from taxine
(Royal Soc Chemistry, Cambridge, 1998)
Highly cytotoxic 7-deoxypaclitaxel analogues are obtained by a semisynthesis starting from taxine-the most abundant naturally occurring taxane diterpene fraction.

Free radical ring expansion and subsequent reactions of intermediary carbon radicals
(Serbian Chemical Society, 1996)
Alkyl radicals, derived from ethyl 1-(bromoalkyl)-2-oxocyclo-alkanecarboxylates or from the corresponding thiohydroxamic esters, undergo a ring expansion reaction and subsequent intermoleculaar addition/elimination reactions. ...
Semisynthesis of Taxol (R): an improved procedure far the isolation of 10-deacetylbaccatin III

From the needles of domestic yew, (Taxus baccata), 10-deacetylbaccatin III (10-DAB) call be isolated in quantities of up to 297 mg per kg of fresh needles. Additional quantities of 10-DAB call be obtained from the extract ...
Formation of allenes by reaction of 1,4-dibromobut-2-ene with dialkyl ketones and base
(Royal Society of Chemistry, 1991)
By reaction of 1,4-dibromo-(E)-but-2-ene with dialkyl ketones and sodium hydride the allenic ketones 3 were obtained as the main products, in addition to the symmetrical unsaturated 1,8-diketones 4.
