Science research in Kuwait—a bibliometric analysis

Journal of Information Science (1987)

F. Al-Kharafi N. R. EL‐RAYYES George M. Janini

Review of the scientific output of the State of Kuwait on the occasion of the 25th anniversary of its independence. Prior to 1970, only about 100 publications were credited to Kuwaiti institutions. The majority of these papers were medical reports published in local journals. In contrast, the 1970s and 1980s witnessed a steady growth with an average doubling time of three years. In 1983, 185 publications were credited to Kuwaiti institutions, and 80% of these appeared in international jour nals. This represents 1.1 articles per 10000 populations, a respectable figure in comparison to Third World standards While Third World countries put more emphasis on research in the life sciences, the distribution of research publications of Kuwait closely match that of the World's scientific publica tions as a whole as seen from the Science Citation Index. 59% of all Kuwaiti authored articles are in the life sciences as against 55% of the international literature. 62.6% of Kuwaiti publications appeared in journals with impact factors ranging from 0- < 1 as against 46.6% of the international literature, and 3.3% of Kuwaiti publications appeared in journals with impact factor > 4 as against 65% of the international litera ture. Furthermore, 43% of Kuwaiti publications were not cited at all as against 25% of the international literature, and Kuwa iti publications averaged 1.8 citations per publication over a 5 year period as against a world average of 4.8 and a Latin American average of 2.9. Overall, the average citedness of papers published from Kuwait comes close to matching that of India, but is inferior in comparison with the standards set by the scientifically ad vanced countries. On the positive side Kuwaiti science appears to be steadily improving.

Effect of Sulfides on the Electrochemical Impedance of Copper in Benzotriazole-Inhibited Media

Journal of The Electrochemical Society (2002)

F. Al-Kharafi B. G. Ateya

The electrochemical impedance of copper in benzotriazole (BTAH)-inhibited media is affected by the addition of sulfides. The caused order of magnitude decreases in the polarization resistance and increases in the double layer capacity. The appearance of sulfur peaks in the X-ray photoelectron spectroscopy (XPS) spectra of the sulfide-treated surfaces is accompained by a significant increase in the atom percent of Cu and a significant decrease in the atom percent of N and of C (and hence, of BTAH) in the surface layer. The results are explained on the basis of the ability of the sulfides to break down the protective BTA film and be adsorbed on the copper surface to catalyze its corrosion. The XPS spectra suggest the formation of copper sulfides. © 2002 The Electrochemical Society. All rights reserved.

Heterocycles. XIII. Nls orbital binding energies of some quinazolines and pyrimidines by XPS

Journal of Heterocyclic Chemistry (1987)

N. R. EL‐RAYYES A. Katrib F. Al-Kharafi B.D. El-Issa

Abstract The X‐ray photoelectron spectra of some quinazolin‐2(1 H )‐ones IIa,b , show only one relatively symmetrical line in the N1s binding‐energy region, where as the corresponding dehydrogenated products IIIa,b and the pyrimidin‐2‐(1 H )‐ones Va,b revealed two well‐resolved spectral lines with an energy difference of more than 1 eV. However, compounds IIc and IIIc gave only one broad unsymmetrical line. Quantum mechanical calculations on compounds IIa and IIIa as well as analogues IIc and IIIc supported the experimental findings.

Monitoring environmental pollution by atmospheric corrosion

Journal of Environmental Science and Health Part A Environmental Science and Engineering (1988)

F. Al-Kharafi M.I. Ismail

Abstract The atmospheric pollution is monitored by out‐door exposure of several commercial alloys including steel, Al, Cu, and brass (Cu‐30Zu) alloys. Three various districts of Kuwait were selected for this study comprising of residential, industrial, and marine areas. The atmospheric pollution level could be monitored directly by observation of the corrosion of the test alloys.

Surface electronic structure-catalytic activity correlation of partially reduced molybdenum oxide(s) for the isomerization of light alkenes and alkanes

Journal of Physics Conference Series (2008)

S. Al-Kandari H. Al-Kandari F. Al-Kharafi A. Katrib

Catalytic activity-surface electronic structure correlation was carried out using surface XPS-UPS techniques. In situ reduction by hydrogen, were carried out at similar experimental conditions to those employed for the catalytic reactions. In the case of MoO3 deposited on TiO2, the reduction to MoO2 state with the bifunctional MoO2(Hx)ac phase on its surface starts at 573 K and reaches a stable state at temperatures between 653–673 K. In the case of alumina support, a strong metal-support interaction takes place during the catalyst preparation, leading to Al2(MoO4)3 complex formation as characterized by XRD. The reduction process(s) of this complex by hydrogen as a function of temperature is different from what is observed in the case of titania support. The changes in the chemical structure of the sample surface in both systems were tested for the catalytic reactions of 1-pentene and n-pentane
