The side-on design is used, for instance, in the type 931, the first mass-produced PMT. Besides the different photocathode materials, performance is also affected by the transmission of the window material that the light passes through, and by the arrangement of the dynodes. Many photomultiplier models are available having various combinations ...
Triple Award Science, commonly referred to as Triple Science, results in three separate GCSEs in Biology, Chemistry and Physics and provide the broadest coverage of the main three science subjects. The qualifications are offered by the five main awarding bodies in England; AQA , Edexcel , OCR , CIE and Eduqas .
Polymethylpentene melts at ≈ 235 °C. It has a relatively low density (0.84 g/cm 3) among plastics and is transparent.It has low moisture absorption, and exceptional acoustical and electrical properties.
To remember the order of taxa in biology (Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species, [Variety]): "Dear King Philip Came Over For Good Soup" is often cited as a non-vulgar method for teaching students to memorize the taxonomic classification of system.
Certain chemical process yield important basic materials for society, e.g., (cement, steel, aluminum, and fertilizer).However, these chemical reactions contribute to climate change by emitting carbon dioxide, a greenhouse gas, through chemical reactions, as well as through the combustion of fossil fuels to generate the high temperatures needed to reach the activation energies of the chemical ...
The New Journal of Chemistry is a monthly peer-reviewed scientific journal publishing research and review articles on all aspects of chemistry.
Under the National Curriculum, all pupils undergo National Curriculum Tests towards the end of Key Stage 2 at Year 6 in the core subjects of English, Mathematics and Science. Pupils normally take GCSE exams in the last two years of Key Stage 4 at Year 11, but may also choose to work towards the attainment of alternative qualifications.
A renaming competition by British newspaper The Guardian in 2009 resulted in their science correspondent choosing the name "the champagne bottle boson" as the best submission: "The bottom of a champagne bottle is in the shape of the Higgs potential and is often used as an illustration in physics lectures. So it's not an embarrassingly grandiose ...
