Organic geochemistry of crude oils from the Intisar oil field (East Sirte Basin, Libya)
(Elsevier, 2016)
Four crude oil samples from the oil fields Intisar A, Intisar D and Intisar E (Sirte Basin, Libya) were investigated in order to define depositional environment, lithology, thermal maturity and geologic age of the corresponding ...
Design and photocatalytic ability of ordered mesoporous TiO2 thin films
(Oxford : Pergamon-Elsevier Science Ltd, 2014)
Homogeneous and crack-free TiO2 films with templated mesoporosity were prepared by the dip coating technique using an evaporation-induced, self-assembly method. The synthesized mesoporous TiO2 films were characterized using ...
Rise time of silicon p-i-n photodiodes
(Elsevier, 1983)
Exact analytical expressions are derived for the short circuit photodiode currents excited by light pulses, under the assumption that the drift carrier velocity linearly depends on the electric field in the depletion layer. ...
Nonacosan-10-ol and n-Alkanes in Leaves of Pinus pinaster
(SAGE Publications Inc., 2020)
In leaf cuticular wax of Pinus pinaster, content of nonacosan-10-ol is high (77.1% on average). n-Alkanes ranged from C18 to C35
with the most dominant C29 (24.8%). The carbon preference index (CPItotal) ranged from 3.1 ...
Water/Aromatic Parallel Alignment Interactions. Significant Interactions at Large Horizontal Displacements
(American Chemical Society (ACS), 2011)
Analysis of crystal structures from the Cambridge Structural Database (CSD) and high level ab initio calculations reveals that the water/aromatic parallel alignment interactions; where the water molecule or one of its 0 H ...
Determination of acid-activated bentonite affinity towards soybean oil pigments during the decolourization process / Određivanje afiniteta kiselinski aktiviranog bentonita prema pigmentima sojinog ulja tokom procesa dekolorizacije
(Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije, Beograd, 2003)
Acid-activated bentonite clays partially or entirely remove pigments from oil by absorption in the process of its decolorization. However, in addition to pigments, they also remove other undesirable components such as ...
Brochosome-Inspired Metal-Containing Particles as Biomimetic Building Blocks for Nanoplasmonics: Conceptual Generalizations
(MDPI, 2021)
Recently, biological nanostructures became an important source of inspiration for plasmonics, with many described implementations and proposed applications. Among them are brochosome-inspired plasmonic microstructures—roughly ...
Comparative study of the effects of a small-scale trout farm on the macrozoobenthos, potamoplankton and epilithic diatom communities
(Springer, 2017)
Trout farms are one of the major sources of
pollution of highland streams and rivers, which are very
sensitive ecosystems otherwise scarcely influenced by
human activities. A trout farm with low annual production
was ...
Removal of Tc-99(VII) by organo-modified bentonite
(Elsevier, 2014)
(99)Technetium is one of the largest components of nuclear waste material. In aqueous solutions Tc-99 is present as the pertechnetate oxoanion, (TcO4-)-Tc-99, which is highly soluble and mobile in groundwater under oxidizing ...
Land degradation and management of red beds in China: Two case studies
(Springer Science and Business Media LLC, 2019)
Red beds cover approximately 9.5% of China, and are home to approximately 144 million people. In total, 83% of these lands are distributed in humid regions making it an important part of research on red bed soil erosion ...
