Polyaniline as a dual flame retardant and electrostatic dissipative additive in polyethylene nanocomposites

Journal of Vinyl and Additive Technology, Volume 31, Issue 2, Page 339-355, March 2025.
Effecft of co‐doping polyaniline with phosphoric acid and phytic acid on the heat release rate of polyethylene. Abstract Polyolefins, such as polyethylene (PE), are highly flammable and electrically insulative, limiting their applicability. The study explored the flame‐retardancy and electrical conductivity of PE/polyaniline (PE/PANI) nanocomposites ...

The Combined Effect of Gas Phase and Condensed Phase Mechanisms in Flame Retardancy of Polybutylene Succinate

Journal of Vinyl and Additive Technology, EarlyView.
A combination of DOPO and APP flame‐retardants results in a V‐0 UL 94 rating. ABSTRACT In this study, we addressed the challenge of eliminating, during combustion, the flaming dripping behavior of polybutylene succinate flame retarded with ammonium polyphosphate, a key barrier to achieving a V‐0 rating in the UL 94 flammability test without excessive ...

The End of Self‐Regulation: Will the Football Governance Act 2025 Fix the National Game?

The Modern Law Review, EarlyView.
The Football Governance Act 2025 is a watershed. It upends the model of self‐regulation that has defined how the game has been run in England and Wales for over a century‐and‐a‐half. The newly created Independent Football Regulator will exercise control over clubs, owners, and competition organisers.

Financial Climate‐Risk Measurement, Impact Funds, and Green Transitions

Journal of Accounting Research, EarlyView.
ABSTRACT Regulators are contemplating or mandating precise measurement of financial climate‐risk exposure to promote sustainable investments. We show that such mandates can be counterproductive in the presence of social funds that catalyze change by subsidizing the adoption of cleaner production technologies.

Real Effects of Subjectivity in Measuring Fair Values

Journal of Accounting Research, EarlyView.
ABSTRACT This study examines how the subjectivity in measuring fair values of assets without readily observable market prices affects investment efficiency and shareholder value. When fair values are objective measures of asset value, they facilitate efficient investment decisions that align with shareholder interests.
