Tailoring the reducibility and catalytic activity of CuO nanoparticles for low temperature CO oxidation
(
Royal Society of Chemistry
, 2018 , Article)
Copper oxide (CuO) nanoparticles have received considerable interest as active and inexpensive catalysts for various gas–solid reactions. The CuO reducibility and surface reactivity are of crucial importance for the high ...
Effect of soil moisture on the response of soil respiration to open-field experimental warming and precipitation manipulation
(
Multidisciplinary Digital Publishing Institute (MDPI)
, 2017 , Article)
Soil respiration (RS, Soil CO2 efflux) is the second largest carbon (C) flux in global terrestrial ecosystems, and thus, plays an important role in global and regional C cycling; moreover, it acts as a feedback mechanism ...
Dynamics of charge evolution in glass capillaries for 230-keV Xe23 + ions
(
American Physical Society
, 2012 , Article)
We have measured the transmission of 230-keV (10-keV/q) Xe23+ ions through insulating tapered glass capillaries of microscopic dimensions. The dynamics of charging and discharging processes have been investigated, evidencing ...

North Africa (interchangeably used with the term ‘Maghrib’) has historically featured as a contributor to Euro-Med cultures and civilisations. Mesopotamia, Egypt and Phoenicia all at one point in time or another mediated ...
A Novel Green Synthesis of Thalidomide and Analogs
(
Hindawi Limited
, 2017 , Article)
Thalidomide and its derivatives are currently under investigation for their antiangiogenic, immunomodulative, and anticancer properties. Current methods used to synthesize these compounds involve multiple steps and extensive ...
Emotion-Cognition Interaction in Nonhuman Primates: Cognitive Avoidance of Negative Stimuli in Baboons (Papio papio)
(
SAGE
, 2016 , Article)
It is well established that emotion and cognition interact in humans, but such an interaction has not been extensively studied in nonhuman primates. We investigated whether emotional value can affect nonhuman primates’ ...

تركّز هذا المقالة على دراسة شخصية نسائية تنتمي إلى صفوة نساء المجتمع، في مرحلة شديدة التقلب وعدم الاستقرار، بين آخر القرن الثامن عشر ومطلع القرن التاسع عشر، إنها "السيدة نفيسة" التي خطفها اللصوص من إحدى القرى الجبلية ...
Ion impact induced ionization/fragmentation dynamics of rare gas Dimers
(
IOP Publishing
, 2013 , Conference Paper)
We have measured the ionization and fragmentation of Helium, Neon and Argon Dimers induced by ion impact and observed two different pathways, the sequential ionization on each atom and the interatomic Cou-lombic decay. © ...
Batch study for herbicide bentazon adsorption onto palm oil fronds activated carbon
(2012 , Article)
The adsorption of herbicide bentazon from aqueous solution onto activated carbon derived from palm oil fronds (PFAC) was investigated through batch study. The effects of both; initial concentration of the bentazon (ranging ...
