Enthalpy of formation of UZr₂ by calorimetry

, 1993
The enthalpy of formation of the intermetallic compound UZr2 at 298 K was determined by high temperature solution calorimetry in which liquid aluminium was used as the solvent. The thermal effects of dissolution of U, Zr and UZr2 in liquid aluminium were

Synergistic Integration of Liquid Crystalline Ordering and Dynamic Networks for Ultrarobust Bismaleimide Vitrimers

Advanced Functional Materials, EarlyView.
A liquid‐crystalline bismaleimide vitrimer integrates local mesogenic organization with exchange‐active ester connectivity, achieving a glass‐transition temperature near 300°C while remaining reprocessable. Stress‐relaxation analysis and temperature‐dependent remolding reveal how segmental mobility, network rearrangement, and structural integrity ...

A theoretical study of thermal vacancy formation enthalpy of disordered FePt doped by Cu, Zn and Ag

, 2018
A fast ordering transition of FePt from an A1 phase to an L1(0) phase is crucial for its promising applications as thin films or nanoparticles. Doping has been taken as an effective approach to achieve this goal.

Acetoacetates Derived From Vegetable Oils: A Platform for Tailor‐Made Vinylogous Urethane Foams

Advanced Functional Materials, EarlyView.
A renewable vegetable oil is converted into acetoacetate‐functionalized precursors for the preparation of catalyst‐free vinylogous urethane foams. Room‐temperature foaming with n‐pentane generates lightweight cellular materials, while the choice of amine enables control over foam structure and mechanical properties.

Photo‐Switchable Molecular Module Programming PET Biodegradation in Aquatic Environments

Advanced Functional Materials, EarlyView.
We address the plastic durability paradox by integrating an itaconic acid–derived pyrrolidone module into polymer backbones. Sunlight in water triggers Norrish Type I ring‐opening and hydrophilization, enabling rapid biodegradation into nontoxic minerals.
