a large population of isomers at once. Fortunately, some isotopes (forms of chemical elements with differing numbers of neutrons) can provide more energetic gamma rays, with less energy input to maintain their isomers, and scientists arepursuingthem as potential solutions to the coherent beam ...
for chemists still did not fully understand how atoms came together to form molecules. In the early 19th century, chemists like Sir Humphry Davy had used electricity to split chemical compounds into their constituent elements, allowing their chemical formulae – that is, the number of each element...

In RNAs, m6A is thought to primarily function by recruiting proteins to specific modified sites (reviewed in refs.3,4,5). However, there is also growing evidence that the modification can impact a range of biochemical processes by changing the behavior of the methylated RNAs10,11. For example...
Stand out (in a good way) from other students applying from your school Demonstrate how you’ve made the most of the opportunities you’ve received (Most importantly) connect back to thepoints of comprehensive review Where to find ideas for your PIQ topics ...
Identify the number of sp3-hybridized carbon atoms in the following compound: (CH3)2C=CHCCl(CH3)2 Explain geometric isomerism in alkenes. How do the properties of geometric isomers differ from one another? Would you expect the carbonyl carbon of benzaldehyd...
Two of the most popular rules to characterize the aromaticity of molecules are those due to Hückel and Baird, which govern the aromaticity of singlet and triplet states. In this work, we study how these rules fade away as the ring structure increases an
How many signals will appear in the proton (1H)NMR spectrum of a molecule? If the answer were as straightforward as just counting the number of protons, then we wouldn’t bother asking the question, now, would we? The purpose of this post is to help you figure out the answer to these...
My other question is: are 5000 items out of 100000 sufficient to give us enough confidence in the 'agreement' that we observe? E.g. how would we calculate the minimal number n of items to pre-test in both assays to reach a significance p<0.05? But in fact, isn't the significance re...
P-92.1.3 defines the rules to determine order of precedence.. each to be applied exhaustively before the next is applied. in brief they are: (1) higher atomic number has priority (2) higher atomic mass has priority (3) when considering double bonds with tetraligand atoms "seqcis" = "Z...
