The abbreviation is not always a short form of the word used in the clue. For example: "Knight" for N (the symbol used in chess notation) Taking this one stage further, the clue word can hint at the word or words to be abbreviated rather than giving the word itself. For example: "About" for C or CA (for "circa"), or RE.
AFUE— annual fuel utilization efficiency. BTL—building tightness limit (building tightness) CDH—cooling degree hours (climate) CFL—compact fluorescent light. COP— coefficient of performance. CRI—color rendering index. EEM—Energy Efficient Mortgage. EER—energy efficiency ratio.
Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. The method was developed in the late 1940s at the University of Chicago by Willard Libby, based on the constant creation ...
Materials Today is a monthly peer-reviewed scientific journal, website, and journal family. The parent journal was established in 1998 and covers all aspects of materials science . It is published by Elsevier and the editors-in-chief are Jun Lou ( Rice University ) and Gleb Yushin ( Georgia Institute of Technology ). [ 1 ]
A crossword (or crossword puzzle) is a word game consisting of a grid of black and white squares, into which solvers enter words or phrases ("entries") crossing each other horizontally ("across") and vertically ("down") according to a set of clues. Each white square is typically filled with one letter, while the black squares are used to ...
Energy materials. Energy materials are used for energy harvesting, storage, and conversion. [1][2] Applications of energy materials include photovoltaics, as well as piezoelectronics. The study of energy materials is usually interdisciplinary, uniting materials scientists, chemists, physicists, biologists, and engineers.
Energy is defined via work, so the SI unit of energy is the same as the unit of work – the joule (J), named in honour of James Prescott Joule [1] and his experiments on the mechanical equivalent of heat. In slightly more fundamental terms, 1 joule is equal to 1 newton metre and, in terms of SI base units. An energy unit that is used in atomic ...
