The calculation showed the semiconducting properties with an indirect band gap of ∼25 eV.Using NaCl as the press-transmitting medium, a single crystal, measuring ∼9 μm, was positioned in a diamond anvil cell.The results fell into the −20 to +100 ppm/☌ range.Under normal operation, the LED housing temperature can increase by as much as 39 ☌ above ambient conditions.When writing a measured unit, the numerical value comes first, followed by a space, followed by the unit.Ĭorrect: 5 V, 1.17 V, 8 ohm, 8 W, 17 cm, 2700 mm, 44 ☌ Incorrect: 2005 was the year that the atomic mass of Na was revised to 22.989 769 28 (2). Incorrect: Na (sodium) has an atomic mass of 22.989 769 28(2), which was revised in the year 2005. Incorrect: E=mc 2 is likely the most famous equation by any scientist.Ĭorrect: The atomic mass of Na (sodium) is 22.989 769 28(2), which was revised in the year 2005. NEVER begin any sentence with digits or symbols or units.Ĭorrect: The most famous equation by any scientist is likely E=mc 2. For more about abbreviations, go here.ĭo not mix a prefix with a unit symbol or abbreviation. It can be confusing because a lowercase unit, like hertz, uses a capitalized symbol or abbreviation/symbol. These are not considered abbreviations they are considered symbols as such, they follow the rules for mathematical symbols instead of traditional grammar rules for writing.ĭo not abbreviate units instead, use their symbols or unit names. Example: 8 kHzįor scientific, technical, or engineering writing, the use of the International System of Units (SI) is preferred. Scientific style (preferred for technical writing): use the digit, the prefix, and the unit symbols.Journalistic style: use the prefix and unit names spelled out.You can write values in one of two ways: journal style or scientific style. 2.6 laws and theories and phenomena, capitalization of. 2.5 kiloohm, kilohm, kilo-ohm, kilo ohm.
