Damage evolution during low cycle fatigue, creep, and their interaction behavior is actually a ductility exhaustion process in response to cyclic and static creep. In this article, a novel viscosity-based model for low cycle fatigue—creep life prediction is presented in an attempt to condition viscosity-based approaches for general use in isothermal and(More)
ii ACKNOWLEDGEMENTS I would first of all like to thank Dr. Schrimpf for his continual support, confidence, and guidance throughout this project. Not only has Dr. Schrimpf been a tremendous source of assistance and encouragement, but I would not even be a graduate student if it were not for Dr. Schrimpf's quick responses to my numerous e-mails, and his(More)
A simple preparation process for the monodispersed pH-sensitive core-shell magnetic microspheres was carried out consisting of chitosan self-assembled on magnetic iron oxide nanoparticles. Meanwhile, glucoamylase was immobilized as a model enzyme on this carrier of Fe3O4/CS microspheres by ionic adsorption. The morphology, inner structure, and high magnetic(More)
Polymeric gene-delivery vectors to achieve lack of toxicity and a balance between protection and DNA release remains a formidable challenge. Incorporating intracellular environment-responsive degradable bonds is an appreciable step toward developing safer transfection agents. In this study, novel, dual-degradable polycation copolymers (Pluronic-diacrylate(More)
Exploration of cost-effective fermentation substrates for efficient lactate production is an important economic objective. Although some organic nitrogen sources are also cheaper, inorganic nitrogen salts for lactate fermentation have additional advantages in facilitating downstream procedures and significantly improving the commercial competitiveness of(More)
Diosmin, a vascular-protecting agent, is practically insoluble in water, and its oral absorption is limited by its extremely low dissolution rate. In this study, β-cyclodextrin (βCD) and 2-hydroxypropyl-β-cyclodextrin (HPβCD) were obtained to improve the solubility and dissolution rate of diosmin. Phase solubility studies of diosmin with βCD and HPβCD in(More)
A versatile method for the design of polydopamine-coated magnetic material with a brush-like structure used for Candida Rugosa lipase (CRL) immobilization was reported in this work. First, polydopamine (PDA) was coated on the surface of Fe3O4 nanospheres (Fe3O4 NPs) with a controllable thickness via dip coating process, and CRL can be immobilized on it(More)
The existence of specular highlight is a great obstacle of shape recovery. For a single gray-scale image with only intensity information, the existed highlight detection methods based on chroma or polarization analysis cannot directly be applied on it. So, a method using surface shape is provided, it makes full use of the imaging process. Through the(More)
In the title compound, C(19)H(13)N(3)O, the dihedral angle between the two quinoline systems is 11.54 (3)°. The mol-ecular conformation is stabilized by intra-molecular N-H⋯N and C-H⋯O hydrogen bonds, with N-H⋯N being bifurcated towards the two N atoms of the two quinoline rings. In the crystal, there are weak intermolecular π-π inter-actions present(More)
