The ideological positions of engineers in Syria

Hanafi, Sari (SAGE Publications, 1997-12)

In this article I examine the potential ability of engineers to assert themselves as modernizers, i.e. to define themselves from the viewpoint of their profession, relative to their country's economic development. In this ...
Global sociology - toward new directions

Hanafi, Sari (SAGE Publications, 2020-01-01)

As newly elected President of the International Sociological Association, I unfold my vision for new directions for global sociology. After defining what a global sociology is, I will point out two particular directions ...
High photo-currents with a zwitterionic thiocyanate-free dye in aqueous-based dye sensitized solar cells

Fayad, R.; Shoker, T.A.; Ghaddar, T.H. (Royal Society of Chemistry, 2016)

We report a new water soluble and stable thiolate/disulfide redox couple (T-/DS) and its use with a new zwitterionic and thiocyanate-free dye (T169) in a 100% aqueous electrolyte system. A DSSC incorporating T169 and the ...
Synthesis and: In vitro cytotoxicity evaluation of ruthenium polypyridyl-sensitized paramagnetic titania nanoparticles for photodynamic therapy

Sakr, M.H.; Halabi, N.M.; Kalash, L.N.; Al-Ghadban, S.I.; Rammah, M.K.; El Sabban, M.E.; Bouhadir, K.H.; Ghaddar, T.H. (Royal Society of Chemistry, 2016)

Following hydrothermal treatment of the final nanocomposites, a ruthenium polypyridyl dye was anchored to the surface. The total potential reactive oxygen species (ROS) generation and singlet oxygen (1O2) production in ...
Time resolved study of three ruthenium(II) complexes at micellar surfaces: A new long excited state lifetime probe for determining critical micelle concentration of surfactant nano-aggregates

Patra, D.; Chaaban, A.H.; Darwish, S.; Saad, H.A.; Nehme, A.S.; Ghaddar, T.H. (Elsevier, 2016)

Three different ruthenium complexes have been synthesized and their luminescence properties in different solvent environments are reported. Luminescence intensities and excited state lifetimes of Ru-I, Ru-II and Ru-III ...
Physicochemical, melissopalynological and antioxidant properties of artisanal honeys from Lebanon

Jaafar, K.; Haidar, J.; Kuraydiyyah, S.; Ghaddar, T.; Knio, K.; Ismail, B.; Toufeili, I. (Springer India, 2017)

Sixteen honeydew and 15 floral honeys from Lebanon were analyzed for pollen spectra and physicochemical parameters. A total of 37 families and 67 taxa were recorded with the honeybees producing honeydew honey exhibiting a ...
Large Enhancement of Dye Sensitized Solar Cell Efficiency by Co-sensitizing Pyridyl- and Carboxylic Acid-Based Dyes

Hilal, H.M.; El Bitar Nehme, M.A.; Ghaddar, T.H. (American Chemical Society, 2018)

Co-sensitization is an attractive approach to enhance the light-harvesting efficiency of a dye sensitized solar cell (DSSC), whereby two or more dyes having complementary absorption spectra are co-adsorbed within a DSSC. ...
Metal-Organic Framework Photocatalyst Incorporating Bis(4′-(4-carboxyphenyl)-terpyridine)ruthenium(II) for Visible-Light-Driven Carbon Dioxide Reduction

Elcheikh Mahmoud, M.; Audi, H.; Assoud, A.; Ghaddar, T.H.; Hmadeh, M. (American Chemical Society, 2019)

In this study, we report the successful incorporation of the photoactive bis(4′-(4-carboxyphenyl)-terpyridine)ruthenium(II) (Ru(cptpy)2) strut into a robust metal-organic framework (MOF), AUBM-4. The single crystal X-ray ...
New pyridyl-based dyes for co-sensitization in dye sensitized solar cells

El Bitar Nehme, V.A.; El Bitar Nehme, M.A.; Ghaddar, T.H. (Elsevier Ltd, 2019)

Co-sensitization is very advantageous in increasing a dye sensitized solar cell's (DSSC)efficiency. It relies on sensitizing the same titania film with two dyes that have complementary absorption spectra. In this report ...
7-O-methylpunctatin, a novel homoisoflavonoid, inhibits phenotypic switch of human arteriolar smooth muscle cells

Fardoun, M.; Iratni, R.; Dehaini, H.; Eid, A.; Ghaddar, T.; El-Elimat, T.; Alali, F.; Badran, A.; Eid, A.H.; Baydoun, E. (MDPI AG, 2019)

Remodeling of arterioles is a pivotal event in the manifestation of many inflammation-based cardio-vasculopathologies, such as hypertension. During these remodeling events, vascular smooth muscle cells (VSMCs) switch from ...
The effect of different ester chain modifications of two guaianolides for inhibition of colorectal cancer cell growth

Aaraj, L.A.; Hayar, B.; Jaber, Z.; Saad, W.; Saliba, N.A.; Darwiche, N.; Ghaddar, T. (MDPI, 2021)

Several sesquiterpene lactones (STLs) have been tested as lead drugs in cancer clinical trials. Salograviolide-A (Sal-A) and salograviolide-B (Sal-B) are two STLs that have been isolated from Centaurea ainetensis, an ...
Eco-Friendly Aqueous Dye-Sensitized Solar Cell with a Copper(I/II) Electrolyte System: Efficient Performance under Ambient Light Conditions

Jilakian, M.; Ghaddar, T.H. (American Chemical Society, 2022)

Organic solvents used in electrolytes of dye-sensitized solar cells (DSCs) are generally toxic and not environmentally safe, which renders their use, especially in indoor solar modules, difficult. In this paper, an ...
Therapeutic potential of flavonoids in cancer: ROS-mediated mechanisms

Slika, H.; Mansour, H.; Wehbe, N.; Nasser, S.A.; Iratni, R.; Nasrallah, G.; Shaito, A.; Ghaddar, T.; Kobeissy, F.; Eid, A.H (Elsevier Masson s.r.l, 2022)

Cancer is a leading cause of morbidity and mortality around the globe. Reactive oxygen species (ROS) play contradicting roles in cancer incidence and progression. Antioxidants have attracted attention as emerging therapeutic ...

Supergravity with mimetic dark matter

Chamseddine, Ali (2021)

We formulate a supersymmetric version of gravity with mimetic dark matter. The coupling of a constrained chiral multiplet to N=1 supergravity is made locally supersymmetric using the rules of tensor calculus. The chiral ...
