This article studies the understanding of acid and base concepts of the 3rd-grade students in middle school. An effective teaching strategy for improving their acid and base concepts was designed by considering students' prior knowledge using Lawson's learning cycle method. The control group was ada...
3. Given its foaming properties, the derivatives of lauric acid (h-dodecanoic acid) are widely used as a base in the manufacture of soaps, detergents, and lauryl alcohol. Lauric acid is a common constituent of vegetable fats, especially coconut oil and laurel oil. It may have a synergistic...

4 Five new 12-membered resorcylic acid lactone derivatives, penicimenolides A-E (1–5), one new ring-opened resorcylic acid lactone derivative penicimenolide F (6), and six known biogenetically related derivatives (7–12) were isolated from the culture broth of a strain of Penicillium...
First of all, apart from recombinant proteins, macromolecular drugs present a new development challenge for pharmaceutical industry; synthetic and analytical tools had to be steadily developed to meet the requirement for macromolecule design at pharmaceutical grade and scale. Secondly, the different phases...

The previous study [3,17] demonstrated that the amine-functionalized mesoporous silicas exhibited good performance for the adsorption of CFA due to acid–base and/or ionic interaction and hydrogen bonding between the amino groups and carboxylic groups in CFA molecules. Nonetheless, the adsorption of ...
