The company’s tuberous name is a nod to theclassic experimentwhere kids turn a potato into a battery using household items including pennies, copper wire and galvanized nails. “That’s really what we’re doing,” Edwards said. “We’re helping people plan and run experiments.”...
Potato battery Difficulty: Medium / Materials: Medium Another way to make a battery—students can use what they have in their pantry. After they create a potato battery, they figure out how to use it and explain why it works. Paper roller coaster Difficulty: Medium / Materials: Basic Test ...
Combining more analytical techniques in the future will likely facilitate metabolomics and the basic research behind it. In plant metabolism research, metabolite analysis has progressed from the analysis of a single or small number of metabolites into the study of a massive amount metabolic data on ...
The principle behind SPME is the partitioning of the analytes between the sample matrix and the extraction medium. When a liquid polymeric coating is used, the amount of analyte absorbed by the coating at equilibrium is directly related to its concentration in the sample: (4.45)m=KfsVtC0VsKfsV...
