Advanced Functional Materials, EarlyView.Two pyridinium‐based ionic liquid templated hybrid manganese halides, (C4Py)2[MnCl4] and (C4Py)2[MnBr4], display similar bulk structures but show significantly different photoluminescence behaviors due to the bromine heavy‐atom effect. Their stable local Mn environments remain intact even in the molten state, allowing applications such as luminescence ...

Speckle‐Engineered Upconversion Amplification in Nanoemulsion‐Templated Hydrogel Microdomes
Advanced Functional Materials, EarlyView.Nanoemulsion‐confined PEGDA microdomes generate speckle‐like excitation fields that strongly amplify upconversion luminescence upon dehydration, enabling filter‐free visible readout with reversible on–off switching. DMD‐based lithography yields scalable, shape‐programmable arrays for moisture‐responsive displays and optical encryption.

Engineering Strategies for Stable and Long‐Life Alkaline Zinc‐Based Flow Batteries
Advanced Functional Materials, EarlyView.Alkaline zinc‐based flow batteries face persistent challenges from unstable zinc deposition, including dendrite growth, passivation, corrosion, and hydrogen evolution, which severely limit cycling stability. Current research addresses these issues through coordinated electrode structuring, electrolyte regulation, and membrane design to control zinc ...

Estimation of the glass transition temperature in metallic glasses
Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 1996Abstract An empirical linear relationship Tg = (0.56 ± 0.05)Tm has been established for metallic glasses. This relationship provides a reasonable estimate of the glass transition temperatue Tg for a metallic system whose melting temperature is known.

Universality of the glass transition temperature
Journal of Non-Crystalline Solids, 1994Abstract A new relation between the glass transition temperature and material constants is presented. It shows a remarkable universality of the glass transition temperature, Tg, for very different types of structural glass. The independence of Fg from the microscopic structure is interpreted as a consequence of the cooperative nature of the glass ...

Glass Transition Temperature of Cyclic Stars
ACS Macro Letters, 2014Cyclic homo- and diblock copolymers with different topologies were synthesized using a combination of "living" radical polymerization and "click" coupling reactions. The topologies included 2- and 3-arm stars, with the arms consisting of either cyclic or linear polystyrene.

The Glass Transition Temperature of Polymer Melts
The Journal of Physical Chemistry B, 2005We develop an analytic theory to estimate the glass transition temperature T(g) of polymer melts as a function of the relative rigidities of the chain backbone and side groups, the monomer structure, pressure, and polymer mass. Our computations are based on an extension of the semiempirical Lindemann criterion of melting to locate T(g) and on the use ...
