OIL PRICE SHOCKS AND STOCK PRICE INFORMATIVENESS: EVIDENCE FROM GCC FIRMS حسب ABOHAMIDA, ALA A.

"…This paper adds to the literature that studies the market reactions to oil price shocks by examining the impact of oil prices volatility on stock price informativeness. Using a sample of firms from the Gulf Corporation Council GCC members (i.e., United Arab Emirates, Kingdom of Bahrain, Kingdom of Saudi Arabia, Sultanate of Oman, State of Qatar, and State of Kuwait) along the period from 2006 to 2021, we document a negative association between oil price uncertainty and the information content of stock price. …"

Aluminum nitride (AlN) reinforced electrodeposited Ni-B nanocomposite coatings حسب Radwan, A. Bahgat

"…The potentiodynamic analysis exhibited that the protection efficiency (PE%) of Ni–B coating is ~20%, which increased to ~53% and ~73% by addition of AlN nanoparticles of 0.6 and 1.2 g L−1, respectively. The corrosion resistance could be credited to the presence of inactive and insulating AlN nanoparticles that filled the existing defects in Ni–B matrix and subsequently decreased the active area exposed to the corrosive electrolyte (3.5 wt.% NaCl).…"
