Complex structures arising from the self-assembly of a simple organic salt Frank–Kasper phases are observed in small organic molecules from the crystallization of fampridine hydrochloride into two distinct structures, indicating that complex self-assembled structures can arise from simple organic salts....
The results showed that the thiobarbituric acid reactive substances (TBARS) values increased gradually with the increase of salt concentration and treatment time. The total volatile base nitrogen (TVB-N) values and total viable counts (TVC) values showed the same trend. Under 3% condition, the ...
PinSalt Dough Volcano Chromatography Chromatography is a technique that involves the separation of a mixture into its parts so you can see each one individually. paper chromatography lab leaf chromatography experiment Pin Solutions A solution is a mixture of 2 or more solutes dissolved in a solvent...
Our analysis of the existing literature data on the bacteria show another common exciting property - they are zinc resistant11,13,14,15,16. It is known that zinc plays an important role in pathogen bacteria-host interactions17,18,19. Pathogenic bacteria could exploit the interaction with Zn2+b...

salt bridge interactions are relatively strong non-bonded interactions between pairs of oppositely charged groups where hydrogen bonding also occurs. To know the mechanism of the anti-sickling drug action, the analysis of electrostatic interactions, especially salt bridges number in GBT440 treated OHbS...
The AP Chemistry lab curriculum offers a fair amount of flexibility.The College Board provides a lab manual to teachers that includes 16 guided inquiry labs. Teachers can then choose at least six of those labs to conduct in class. The other ten or more labs in the course may be teacher-di...
The aim of this study was to produce non-fermented preserved sea fennel leaves in different pickle juices prepared with apple cider vinegar, wine vinegar and alcoholic vinegar, and to compare their chemical parameters (pH, titratable acidity and salt content), organoleptic properties (color and tex...
Predictive toxicity and structure–activity relationships (SARs) are raising interest since the number of nanomaterials has become unmanageable to assess their toxicity with a classical case-by-case approach. Graphene-based materials (GBMs) are among the
Before adopting the experiment for all general chemistry lab students, it was pretested with small groups of second year students, and with one pilot class of 30 general chemistry students. Both the prelab and experiment were judged a success. From a chemistry content perspective, almost all ...
