Ahmed H. Zewail
Ahmed Hassan Zewail ( ar, أحمد حسن زويل, ; February 26, 1946 – August 2, 2016) was an Egyptian-American chemist, known as the "father of femtochemistry". He was awarded the 1999 Nobel Prize in Chemistry for his work on femtochemistry and became the first Egyptian to win a Nobel Prize in a scientific field, and the second African to win a Nobel Prize in Chemistry. He was the Linus Pauling Chair Professor of Chemistry, Professor of Physics, and the director of the Physical Biology Center for Ultrafast Science and Technology at the California Institute of Technology. Early life and education Ahmed Hasan Zewail was born on February 26, 1946, in Damanhur, Egypt, and was raised in Desouk. He received a Bachelor of Science and Master of Science degrees in Chemistry from Alexandria University before moving to the United States to complete his PhD at the University of Pennsylvania supervised by Robin M. Hochstrasser. Career After completing his PhD, Zewail did postdoctoral re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Damanhour
Damanhur ( ar, دمنهور ', ; Egyptian: ''Dmỉ-n-Ḥr.w''; cop, ⲡϯⲙⲓⲛ̀ϩⲱⲣ '; ; grc, Ἑρμοῦ πόλις μικρά ') is a city in Lower Egypt, and the capital of the Beheira Governorate. It is located northwest of Cairo, and E.S.E. of Alexandria, in the middle of the western Nile Delta. Etymology Damanhur was known in the ancient Egyptian language as ''The City of (the god) Horus'', on the grounds that it was a center for the worship of this god. It was also known by other names: in the Egyptian texts, "Behdet"; in the Greek texts "Hermou Polis Mikra" (the lesser city of Hermes), translated to Latin by the Romans as "Hermopolis Parva"; the name "Obollenoboles" (or Apollonopolis) associated it with the Greek god Apollo, and it was also called "Tel Ballamon". Now it is known by its oldest name, which was rendered in Bohairic cop, Ⲡⲓϯⲙⲓⲛ̀ϩⲱⲣ or Ⲡⲧⲓⲙⲉⲛϩⲱⲣ, and thus rendered in Arabic as "Damanhur" following the Islamic c ...

Order Of The Nile
The Order of the Nile (''Kiladat El Nil'') was established in 1915 and was one of the Kingdom of Egypt's principal orders until the monarchy was abolished in 1953. It was then reconstituted as the Republic of Egypt's highest state honor. Sultanate and Kingdom of Egypt The Order was established in 1915 by Sultan Hussein Kamel of Egypt for award to persons who had rendered useful service to the country. It ranked beneath the Order of Ismail and was frequently awarded to British officers and officials serving in Egypt, as well as distinguished Egyptian citizens.The order comprised five classes: # Grand Cordon: Badge worn from a sash over the right shoulder, with a star on the left chest. # Grand Officer: Badge worn around the neck, with a smaller star on the left chest. # Commander: Badge worn around the neck. # Officer: Badge worn on the left chest from a ribbon bearing a rosette. # Knight: Badge worn on the left chest from a plain ribbon.

Femtochemistry
Femtochemistry is the area of physical chemistry that studies chemical reactions on extremely short timescales (approximately 10−15 seconds or one femtosecond, hence the name) in order to study the very act of atoms within molecules (reactants) rearranging themselves to form new molecules (products). In a 1988 issue of the journal ''Science'', Ahmed Hassan Zewail published an article using this term for the first time, stating "Real-time femtochemistry, that is, chemistry on the femtosecond timescale...". Later in 1999, Zewail received the Nobel Prize in Chemistry for his pioneering work in this field showing that it is possible to see how atoms in a molecule move during a chemical reaction with flashes of laser light. Application of femtochemistry in biological studies has also helped to elucidate the conformational dynamics of stem-loop RNA structures. Many publications have discussed the possibility of controlling chemical reactions by this method, but this remains cont ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Egypt
Egypt ( ar, مصر , ), officially the Arab Republic of Egypt, is a transcontinental country spanning the northeast corner of Africa and southwest corner of Asia via a land bridge formed by the Sinai Peninsula. It is bordered by the Mediterranean Sea to the north, the Gaza Strip of Palestine and Israel to the northeast, the Red Sea to the east, Sudan to the south, and Libya to the west. The Gulf of Aqaba in the northeast separates Egypt from Jordan and Saudi Arabia. Cairo is the capital and largest city of Egypt, while Alexandria, the second-largest city, is an important industrial and tourist hub at the Mediterranean coast. At approximately 100 million inhabitants, Egypt is the 14th-most populated country in the world. Egypt has one of the longest histories of any country, tracing its heritage along the Nile Delta back to the 6th–4th millennia BCE. Considered a cradle of civilisation, Ancient Egypt saw some of the earliest developments of writing, agriculture, ur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Davy Medal
The Davy Medal is awarded by the Royal Society of London "for an outstandingly important recent discovery in any branch of chemistry". Named after Humphry Davy, the medal is awarded with a monetary gift, initially of £1000 (currently £2000). History The medal was first awarded in 1877 to Robert Wilhelm Bunsen and Gustav Robert Kirchhoff "for their researches & discoveries in spectrum analysis", and has since been awarded 140 times. The medal is awarded annually and, unlike other Royal Society medals (such as the Hughes), has been awarded without interruption since its inception. The medal has been awarded to multiple individuals in the same year: in 1882, for example, it was awarded to Dmitri Mendeleev and Julius Lothar Meyer "for their discovery of the periodic relations of the atomic weights"; in 1883 to Marcellin Berthelot and Julius Thomsen "for their researches in thermo-chemistry"; in 1893 to Jacobus Henricus van 't Hoff and Joseph Achille Le Bel "In recognition of thei ...

Priestley Medal
The Priestley Medal is the highest honor conferred by the American Chemical Society (ACS) and is awarded for distinguished service in the field of chemistry. Established in 1922, the award is named after Joseph Priestley, the discoverer of oxygen who immigrated to the United States of America in 1794. The ACS formed in 1876, spearheaded by a group of chemists who had met two years previously in Priestley's home. The Priestley Medal is commonly awarded to scientists who are advanced in their fields, as it is intended to commemorate lifetime achievement. When the ACS started presenting the Priestley Medal in 1923, they intended to award it every three years. This continued until 1944, when it became an annual award.

Wolf Prize
The Wolf Prize is an international award granted in Israel, that has been presented most years since 1978 to living scientists and artists for ''"achievements in the interest of mankind and friendly relations among people ... irrespective of nationality, race, colour, religion, sex or political views."'' History The prize is awarded in Israel by the Wolf Foundation, founded by Ricardo Wolf, a German-born inventor and former Cuban ambassador to Israel. It is awarded in six fields: Agriculture, Chemistry, Mathematics, Medicine, Physics, and an Arts prize that rotates between architecture, music, painting, and sculpture. Each prize consists of a diploma and US$100,000. The awards ceremony typically takes place at a session in the Knesset. The prize is described by the Foundation as being "awarded annually", but is not in fact awarded every year: between 2000 and 2010, only six prizes were awarded in most fields, and only four in Physics.
