This study aimed at determining sol–gel transition temperatures of microfiltered skim milk retentates for different protein levels (6, 8 and 10% (w/w)) and a wide pH range (native pH to 4.6) by means of small-amplitude oscillatory shear rheology. For a pH of 5.4 to 5.0, the sol–...
这项研究通过“嵌段共混物”生物材料的表征和药物释放曲线,还通过细胞实验,体外渗透和体内透皮递送研究证明了这一概念。相关论文以题为An Intelligent Transdermal Formulation of ALALoaded Copolymer Thermogel with Spontaneous Asymmetry by Using TemperatureInduced Sol–Gel Transition and Gel–Sol (Suspension) Transit...
Oakenfull et al.9 have reported the transition temperature and the transition enthalpy for the sol–gel transition of k-carrageenan systems. Using their data for a 0.5 wt% system, we can report ΔSV = 0.16 mJ cm − 3 K − 1. Del Carmen Núñez-Santiago and Tecante have also ...
This paper deals with the behaviour of hydrolyse d Polyacrylamide solutions in the presence of chromium III. First, using potentiometry and spectroscopy, we study the complexation between chromium III and sodium acetate used as a low molecular weight model for the polymer. Then the same methods are...
We study the fluctuations of a Brownian microparticle trapped using optical tweezers in a gelatin solution undergoing a fast local temperature quench below that required for the sol鈥揼el transition. Contrary to what has previously been reported, we observe no anomalous fluctuations in the particle's...
Temperature-induced sol-gel transition and microgel formation in α-actinin cross-linked actin networks: A rheological study We have studied the sol-gel transition, the viscoelastic and the structural properties of networks constituted of semiflexible actin filaments cross-linked...

are some of the processes of sol gel (Piveteauet al., 2001). Meanwhile, coating via sol gel is preferred for Ti alloys, primarily because of low temperature for processing that hinders transition between alpha and beta phases (Metikos-Hukovicet al., 2003). The benefits ofsol gel coating...
its glass transition temperature up to ~41%. Therefore, the combined use of FR elements such as silicon and nitrogen and the flexibility of sol-gel routes can facilitate the synthesis of hybrid structures containing well dispersed inorganic phases, which could replace halogen-based flame retardants....
摘要: The dynamics of the colloidal probes in a gelatin solution during the time-dependent sol-gel transition was investigated by multi-particle tracking. The relationship between the re... 查看全部>>DOI: 10.1039/c7sm02556d 年份: 2018
