Twenty-three rigorously chosen, peer-reviewed contributions from the foreign convention on natural and utilized Chemistry (ICPAC 2014) are featured during this edited booklet of lawsuits. ICPAC 2014, a biennial assembly, was once held in Mauritius in June 2014. The subject matter of the convention was once “Crystallizing rules: The position of Chemistry” and it matched the assertion of the yr 2014 because the foreign yr of Crystallography.

Consider reducing the scale of an experiment, for example, by running a reaction with 3 grams instead of 10 grams of a starting compound. This saves the costs of starting materials, uses less solvent, uses less energy (if heated), and produces less waste. Fifty years ago, before instrumental analysis, products could only be analyzed with subsequent chemical tests. Today, modern instrumentation often requires only a very small sample size for analysis. This allows some reactions to be “scaled down” considerably.

1] The instructor did not recognize the hazard. Why? [#2] Hot glass looks like cold glass and the instructor did not think a student would hand a hot object to another person. Why? [#3] The instructor did not have enough safety education or experience in working with students. Why? [#4] The safety education the instructor received did not address this topic. Why? [#5] The organization (college) failed to adequately educate instructors about the speciﬁc and general risks in chemistry labs. ” they both end up at the same root cause: inadequate instructor education in safety.
