Nuclear magnetic resonance spectroscopy provides non-invasive and non-destructive access to the chemistry of human tissue in situ. Two studies presented in this issue of the Journal [1, 2] apply this new technique on skeletal muscle metabolism in patients with chronic lung disease. In the 1940s, E. Purcell and F. Bloch discovered that electromagnetic radio-frequency energy could be used to inte...

fatemeh karimi tabar was born in asadabad/hamedan (iran) in 1986. she completed her b.sc. in chemistry in 2008 from bu-ali sina university, hamedan, iran. she was graduated from m.sc. degree in organic chemistry from shiraz university 2010, shiraz, iran. she is currently organic chemistry ph.d student under the supervision of prof. m.a. zolfigol and prof. a. khazaei in department of chemistry a...

(68)Ge/(68)Ga radionuclide generators have been investigated for almost fifty years, since the cyclotron-independent availability of positron emitting (68)Ga via the (68)Ge/(68)Ga system had always attracted researches working in basic nuclear chemistry as well as radiopharmaceutical chemistry. However, it took decades and generations of research (and researchers) to finally reach a level of (6...

Independent databases of nuclear constants for Neutron Activation Analysis (NAA) have been independently maintained by the physics and chemistry communities for many year. They contain thermal neturon cross sections σ0, standardization values k0, and transition probabilities Pγ. Chemistry databases tend to rely upon direct measurements of the nuclear constants k0 and Pγ which are often publishe...

In this note, we propose, apparently for the first time, a new type of controlled nuclear fusion called ”intermediate” because occurring at energies intermediate between those of the ”cold” and ”hot” fusions, and propose a specific industrial realization. For this purpose: 1) We show that known limitations of quantum mechanics, quantum chemistry and special relativity cause excessive departures...
