OBJECTIVE This retrospective study investigated the impact of a required vs an optional remake requirement on student performance in a compounding laboratory course in which students' compounded preparations were analyzed. METHODS The analysis data for several preparations made by students over a 3-year period were compared for differences in the analyzed content of the active principal ingre...

Being different from common sensing molecules existing as monomer in solution, the gelators as sensing molecules self-assembled together in gels. Therefore, the interaction strength between gelators is believed as an important factor for gels to recognize selectively anions. In this paper, we choose two gelators, presenting similar binding sites for anions, but different strengths in intermolec...

Short-chain ceramides, such as N-acetoyl-d-erythro-sphingosine (C2), have a remarkable ability to structure edible oils, such as canola oil, into self-standing organogels without any added saturated or trans fats. These short-chain ceramides are ubiquitously found in foods ranging from eggs to soybeans. As the ceramide fatty acid chain length increases, there is an increase in the melting tempe...

Coordination complexes are widely used to tune the mechanical behaviors of polymer materials, including tensile strength, stretchability, self-healing, and toughness. However, integrating multivalent functions into one material system via solely coordination is challenging, even using combinations metal ions ligands. Herein, a single-step process described silver-based as cross-linkers enable h...
