Foams and surfactants are relatively rare in biology because of their potential to harm cell membranes and other delicate tissues. However, in recent work we have identified and characterized a number of natural surfactant proteins found in...
Processing-Size Correlations in the Preparation of Magnetic Alginate Microspheres Through Emulsification and Ionic Crosslinking [0.03%]
通过乳化和离子交联制备磁性海藻酸盐微球的过程尺寸相关性研究
Andrew R Garcia,Christopher Lacko,Catherine Snyder et al.
Andrew R Garcia et al.
Magnetic alginate microspheres are biocompatible due to their alginate matrix, and motion-controllable by applied magnetic fields due to their magnetic character. Therefore, they have the potential of being used as vessels to a broad variet...
THE ROLE OF THE ASYMMETRIC BOLAAMPHIPHILIC CHARACTER OF VECAR ON THE KINETIC AND STRUCTURAL ASPECTS OF ITS SELF-ASSEMBLY: A MOLECULAR DYNAMICS SIMULATION STUDY [0.03%]
VECAR手性分子在聚集过程中的作用机制：分子动力学模拟研究
Hye-Young Kim,Brian R Novak,Bijay Shrestha et al.
Hye-Young Kim et al.
VECAR are novel bolaamphiphilic molecules consisting of two hydrophilic molecular groups, a carnosine derivative and a chromanol group, covalently linked by a hydrophobic alkyl spacer of varying length. Despite the potential for application...
Hydrodynamically-driven drug release during interstitial flow through hollow fibers implanted near lymphatics [0.03%]
