Majid Shahryari was martyred while Fereydoun Abbasi was injured.
The terrorist attacks took place this morning when the two professors were on their ways to Shahid Beheshti Universtiy in north of Tehran where they worked.
Shahryari, who was accompanied by his wife, was killed instantly after two terrorists driving a motorbike attacked his car. His wife is in good condition in a nearby hospital.
In a separate incident also this morning, Abbasi and his wife were injured in a terrorist attack. The two survived the attack and are in good conditions in hospital.
Tehran Police Chief Brigadier General Hossein Sajedinia said a motorcycle approached Shahriari's car and attached a bomb to the car which exploded a few seconds later.
He added that in a separate incident terrorists this time attached another bomb to Abbasi's car and escaped. He noted that the professor and his wife were wounded in the attack and are now in good health conditions.
Resolution 1747 adopted by the United Nations Security Council in March 2007 against the Islamic Republic cited the name of Abbasi as a "nuclear scientist," thus suggesting that perpetrators behind the assassination could be traced through those who included the professor's name in the UN resolution.
A distinguished Iranian physics professor, Masoud Alimohammadi, was killed in a remote-controlled bomb blast in front of his home in northern Tehran Jan 12, 2010.
