Accounting for Cooperativity in the Thermotropic Volume Phase Transition of Smart Microgels

Monodisperse Thermoresponsive Microgels with Tunable Volume-Phase Transition Kinetics

Stimuli-sensitive hydrogel microspheres or microgels are polymeric particles that consist of cross-linked three-dimensional networks. They shrink or swell significantly by expelling or absorbing large amounts of water in response to external stimuli, such as changes in temperature, pH, electric or magnetic fields. The chemical composition of the microgel determines the stimulus that can trigger...

Rheological properties of suspensions of thermo-responsive poly(N-isopropylacrylamide) microgels undergoing volume phase transition

The rheological properties of suspensions of thermo-responsive poly(N-isopropylacrylamide) (PNIPAM) microgels are investigated in the swollen and collapsed states using oscillatory and long-time creep measurements. In the swollen state with repulsive interparticle interaction, the zero shear viscosity and quasi-plateau modulus are solely governed by the effective volume fraction (φeff) and are ...

the test for adverse selection in life insurance market: the case of mellat insurance company

انتخاب نامساعد یکی از مشکلات اساسی در صنعت بیمه است. که ابتدا در سال 1960، توسط روتشیلد واستیگلیتز مورد بحث ومطالعه قرار گرفت ازآن موقع تاکنون بسیاری از پژوهشگران مدل های مختلفی را برای تجزیه و تحلیل تقاضا برای صنعت بیمه عمر که تماما ناشی از عدم قطعیت در این صنعت میباشد انجام داده اند .وهدف از آن پیدا کردن شرایطی است که تحت آن شرایط انتخاب یا کنار گذاشتن یک بیمه گزار به نفع و یا زیان شرکت بیمه ...
