David Alexander Britz (born November 23, 1980) is an American scientist and engineer who is best known for his contributions to the field of materials science and nanotechnology.
In 2004, Britz and his colleagues at Oxford and the University of Nottingham won a place in the Guinness Book of World Records for creating the world's smallest test tube, by performing chemical reactions inside of carbon nanotubes: "the nanotube has an inner diameter of approximately 1.2 nanometres, and a length of about 2 micrometers. Its volume is two zeptolitres (a zeptolitre is 10−21 litres), and around 2,000 molecules react in that space."
Britz graduated magna cum laude from the University of Virginia School of Engineering and Applied Science in Mechanical Engineering. He completed his Doctor of Philosophy in Materials Science in the UK at the University of Oxford, Christ Church, Oxford college in the Department of Materials, and completed his doctoral thesis, titled "Structure and Bonding of Fullerenes and Nanotubes", in 2005. During his work at Oxford, David Britz created more than ten new carbon nanotube- and fullerene-based materials and processes. He has been awarded Honorable Mention for the 2002 National Science Foundation Graduate Research Fellowship.
David (Greek: Δαυΐδ; fl. 6th century) was a Greek scholar and a commentator on Aristotle and Porphyry.
He may have come from Thessaly, but in later times he was confused with an Armenian of the same name (David Anhaght). He was a pupil of Olympiodorus in Alexandria in the late 6th century. His name suggests that he was a Christian.
Three commentaries to Aristotle's works attributed to him have survived: as well as an introduction to philosophy (prolegomena):
All these works will be published, with an English translation, in the series Commentaria in Aristotelem Armeniaca - Davidis Opera (five volumes), edited by Jonathan Barnes andValentina Calzolari.
Another anonymous commentary on Porphyry's Isagoge which was falsely ascribed to Elias (pseudo-Elias), was also falsely ascribed to David.
David (Bulgarian: Давид) (died 976) was a Bulgarian noble, brother of Emperor Samuel and eldest son of komes Nicholas. After the disastrous invasion of Rus' armies and the fall of North-eastern Bulgaria under Byzantine occupation in 971, he and his three younger brothers took the lead of the defence of the country. They executed their power together and each of them governed and defended a separate region. He ruled the southern-most parts of the realm from Prespa and Kastoria and was responsible for the defence the dangerous borders with Thessalonica and Thessaly. In 976 he participated in the major assault against the Byzantine Empire but was killed by vagrant Vlachs between Prespa and Kostur.
However, there's also another version about David’s origin. David gains the title "comes" during his service in the Byzantine army which recruited many Armenians from the Eastern region of the empire. The 11th-century historian Stepanos Asoghik wrote that Samuel had one brother, and they were Armenians from the district Derjan. This version is supported by the historians Nicholas Adontz, Jordan Ivanov, and Samuil's Inscription where it’s said that Samuel’s brother is David. Also, the historians Yahya and Al Makin clearly distinguish the race of Samuel and David (the Comitopouli) from the one of Moses and Aaron (the royal race):
David (Spanish pronunciation: [daˈβið]) officially San José de David is a city and corregimiento located in the west of Panama. It is the capital of the province of Chiriquí and has an estimated population of 144,858 inhabitants as confirmed in 2013. It is a relatively affluent city with a firmly established, dominant middle class and a very low unemployment and poverty index. The Pan-American Highway is a popular route to David.
The development of the banking sector, public construction works such as the expansion of the airport and the David-Boquete highway alongside the growth of commercial activity in the city have increased its prominence as one of the fastest growing regions in the country. The city is currently the economic center of the Chiriqui province and produces more than half the gross domestic product of the province, which totals 2.1 billion. It is known for being the third-largest city in the country both in population and by GDP and for being the largest city in Western Panama.
