As for organic chemistry being a prerequisite here; organic chemistry courses here spend a lot of time talking about qualitative molecular orbital theory and using it to explain chemical reactions. MO theory and other bonding theories don't see a lot of time in our gen. chem courses (for the...
is more stable, however, because the bond between the amino acids is harder to break down. It was developed over 20 years and is 8,000 times sweeter than sugar. According to the neotame Web site, only six milligrams are needed to sweeten a 12-ounce beverage. Because neotame doesn't ...
Many students in a Gen Chem course that required at least a year of intro chem would enroll with no or little chem (or have a lagtime of 3 years or more since their last chem class) and would drop because they didn't have the background or were so over-committed with too many clas...
This "2007 Problem" of transferring skills as the baby-boomer gen- eration enters mandatory retirement came 10 years earlier at the Aboshi Plant than other chemical complexes, because a large number of techni- cians were hired in 1951 when production of cellulose acetate started. To solve the...
20. If you want to make sure you are making damson gin (rather than some other random-purple-ish-plum-sorta-thing gin), buy your own damson tree. If you need help picking damsons, small children come in handy (although those are harder to buy – this is one we grew ourselves). The...
so let me link to an excellent description about how molecular shape and symmetry, in addition to the usual electronic factors, play a role in dictating the strength of intermolecular forces of a solid, and the resulting melting point:http://www.masterorganicchemistry.com/2010/07/09/chemical-...
Contaminant accumulation in the media is less of an issue because green roofs are receiving rainfall rather than stormwater runoff, so incoming contaminant concentrations are relatively low. This also means that the relatively clean rainwater, however, has the potential to pick up organic matter and...
taxiformis revealed significantly lower CAT activity than non-biofortified ones (i.e., CTR-HW; p < 0.001), with 1.5-AT treatment showing the lowest activity (corresponding to a 73.5% reduction; Figure 2A). Regarding GST, only fish fed with 1.5% and 3% A. taxiformis showed a ...
Moreover, the exchange bias effect can appear when the assembly is cooled in a static magnetic field across a critical temperature, below which the anisotropy energy of the harder component (antiferromagnetic or ferrimagnetic, possibly showing a spin-glass-like behavior) is larger than the exchange...
