Dual‐Functional Sulfonated Nanocellulose for Proton Exchange Membranes With High Proton Conductivity at Low Humidity

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A scalable dual‐functional strategy yields simultaneously sulfonated and nanosized cellulose for proton exchange membranes with continuous hydrogen‐bond networks. These sustainable membranes exhibit low‐humidity proton conductivity twofold higher than Nafion 212, providing a robust solution for next‐generation fuel cells.

Does a More Functionally Diverse Top Management Team Make the Financial Statements More Comparable?

open access: yesJournal of Corporate Accounting &Finance, EarlyView.
ABSTRACT We examine whether top management team (TMT) functional diversity affects financial statement comparability. Drawing upon upper echelons theory and the information sharing perspective in diversity research, we argue that TMT functional diversity produces more comparable financial statements due to better information sharing and integration ...
