Context and question: Quantum dots (QD) are semiconductor nanocrystals that possess unique optical properties. Their emission color can be tuned from the visible throughout the infrared spectrum. This allows quantum dot LEDs to create almost any color on the CIE diagram. This provides more color options and better color rendering than white LEDs since the emission spectrum is much narrower, characteristic of quantum confined states. There are two types of schemes for QD excitation. One uses photo excitation with a primary light source LED (typically blue or UV LEDs are used). The other is direct electrical excitation first demonstrated by Alivisatos et al.
How many types of schemes are there in non-Quantum Dot LED excitation?
Answer: unanswerable
Context and question: Eton is one of ten English HMC schools, commonly referred to as "public schools", regulated by the Public Schools Act of 1868. Following the public school tradition, Eton is a full boarding school, which means all pupils live at the school, and it is one of four such remaining single-sex boys' public schools in the United Kingdom (the others being Harrow, Radley, and Winchester) to continue this practice. Eton has educated 19 British prime ministers and generations of the aristocracy and has been referred to as the chief nurse of England's statesmen. Charging up to 11,478 per term (there are three terms per academic year) in 2014/15, Eton is the sixth most expensive HMC boarding school in the UK.
How many public schools are regulated by the 1868 Public Schools Act?
Answer: ten
Context and question: In June 2009 the first major building work at the abbey for 250 years was proposed. A coronaa crown-like architectural featurewas intended to be built around the lantern over the central crossing, replacing an existing pyramidal structure dating from the 1950s. This was part of a wider 23m development of the abbey expected to be completed in 2013. On 4 August 2010 the Dean and Chapter announced that, "[a]fter a considerable amount of preliminary and exploratory work", efforts toward the construction of a corona would not be continued. In 2012, architects Panter Hudspith completed refurbishment of the 14th-century food-store originally used by the abbey's monks, converting it into a restaurant with English Oak furniture by Covent Garden-based furniture makers Luke Hughes and Company.
Who supplied the furniture for the restaurant?
Answer:
Luke Hughes and Company
