Synthesis and Biological Activities of Thio-avarol Derivatives
(Amer Chemical Soc, Washington, 2008)
Eleven new thio-avarol derivatives (3-13) were synthesized. Their antimicrobial, brine shrimp lethality, and free-radical scavenging activities and acetylcholinesterase inhibition, together with 12 already reported ...
Optical properties of PbTe and PbSnTe doped with Cr
(Elsevier Science Sa, Lausanne, 2009)
Single crystal samples of PbTe and PbSnTe doped with Cr were made using the Bridgman technique. Far infrared diagrams of PbTe samples doped with 0.4 at.%, 0.8 at.% and 1 at.% Cr and also of Pb(0.9)Sn(0.1)Te doped with 0.4 ...
Nitrate transport in cucumber leaves is an inducible process involving an increase in plasma membrane H+-ATPase activity and abundance
(Bmc, London, 2012)
Background: The mechanisms by which nitrate is transported into the roots have been characterized both at physiological and molecular levels. It has been demonstrated that nitrate is taken up in an energy-dependent way by ...
Influence of the ratio between Ni and BaCe0 9Y0 1O3-delta on microstructural and electrical properties of proton conducting Ni-BaCe0 Y-9(0) O-1(3-delta) anodes
(Elsevier Science Sa, Lausanne, 2011)
Cermet anode substrates Ni-BaCe0 9Y0 1O3-delta (Ni-BCY10) with varied ratios between Ni and BCY10 were prepared BCY10 powders were prepared by the citrate-nitrate auto-combustion method and anode substrates were prepared ...
New Route for Stabilization of 1T-WS2 and MoS2 Phases
(Amer Chemical Soc, Washington, 2011)
The phenomenon of a partial 2H -> 1T phase transition within multiwalled WS2 nanotubes under substitutional rhenium doping is discovered by means of high-resolution transmission electron microscopy. Using density-functional ...
Evaluation of antioxidant capacity of Allium ursinum L. volatile oil and its effect on membrane fluidity
(Elsevier Sci Ltd, Oxford, 2008)
A total of 20 components were identified in Allium ursinum volatile oil (AUVO) by GC-MS, and 10 of them are found for the first time in this plant species. The antioxidant capacity of AUVO was examined by beta-carotene-linoleic ...
Star-shaped oligobenzoates: Non-conventional mesogens forming columnar helical mesophases
(Wiley-V C H Verlag Gmbh, Weinheim, 2008)
Star-shaped mesogens with a phloroglucinol or a trimesic acid core and oligobenzoate arms with up to five repeating units have been synthesised. non-conventional mesogens form various columnar mesophases over a broad ...

(Wiley-Blackwell, Hoboken, 2009)
In Europe Phytophthora ramorum has been reported on a range of
ornamentals as well as on a limited number of tree species in at least in 11
countries: UK, Spain, Belgium, Germany, the Netherlands, Italy, France,
Switzerland, ...
Designing Electrical Contacts to MoS2 Monolayers: A Computational Study
(Amer Physical Soc, College Pk, 2012)
Studying the reason why single-layer molybdenum disulfide (MoS2) appears to fall short of its promising potential in flexible nanoelectronics, we find that the nature of contacts plays a more important role than the ...
Strontium titanate films prepared by spray pyrolysis
(Elsevier Sci Ltd, Oxford, 2004)
Strontium titanate thin films were prepared by spray pyrolysis technique. Deposition parameters, such as solution concentration, time and temperature of deposition, and flow rate of carrier gas were optimized to obtain ...
