Dalton's law, law of multiple proportions - (chemistry) law stating that when two elements can combine to form more than one compound the amounts of one of them that combines with a fixed amount of the other will exhibit a simple multiple relation law of mass action - (chemistry) the la...
The sun is primarily composed of hydrogen atoms, which collide under tremendous pressure and temperature with each other to form helium. This process, known as nuclear fusion, is how the sun generates energy, and that energy output is steadily increasing, albeit at a pace far too slow for us...
3. Sloes are the fruit of the blackthorn bush – you can find these all over the place in the UK. They can often be found at the edges of farm fields; they form dense and thorny hedges and do a good job of keeping livestock in fields and people out of them. Sloes are not somethi...

isomers of the bicyclic octapeptide α-amanitin, which presents a macrolactam with a tryptathionine cross-link forming a handle, has been reported under the term of atropoisomers. Here, the authors synthesize its analogs and analyse their isomers, proposing and describing for them the term an...
The long-term cultivation of tea plants without fertilization can severely decrease yield, but it remains unclear whether this soil nutrient deficiency affects tea quality. In this study, tea plants (Camellia sinensis (L.) Kuntze) cultivated in unfertilized soil for 11 years were analyzed. The so...
