Thermally Induced Gelling Systems Based on Patchy Polymeric Micelles
Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.A novel strategy to design thermally induced gelling systems with tunable material properties is reported. Polymeric mixed‐shell micelles displaying multiple thermosensitive patchy domains formed hydrogels by assembling into well‐entangled worm‐like network structures upon heating to body temperature. The patchy micelle design significantly affects the

, 2020 An implied volatility is the volatility implied by the market price of an option based on the Black Scholes option pricing model. A volatility surface is derived from quoted volatilities that provides a way to interpolate an implied volatility at any strike and maturity. Unlike in other markets that quote volatility versus strike directly, the FX smile

The implicit models of the option valuation
Management Letters/Cuadernos de Gestión, 2004 Of the alternative approaches to the Black-Scholes options valuation model, the implied models have had the largest development in last years. In this approach there are different alternatives: implied trees, deterministic volatility function models and ...
