Mergers and Acquisitions as Navigators of Climate Policy Shocks: Evidence from the NOx Budget Trading Program

open access: yesFinancial Management, EarlyView.
ABSTRACT We examine how mergers and acquisitions (M&As) enable firms to adapt to climate policy shocks. Exploiting the adoption of the Nitrogen Oxides (NOx) Budget Trading Program (NBP) across US states as an exogenous shock, we find that firms with NOx‐emitting plants subject to the NBP are more likely to engage in M&As, particularly through vertical ...

Abnormal Expansion Along the Synthesis of Zinc Stannate: A Way for Porous Ceramics Without Addition of Pore Generators

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 2, February 2026.
The abnormal expansion associated with the simultaneous synthesis and sintering of Zn2SnO4 from ZnO and SnO2 is due to the reaction mechanism and correlated with the conversion. This phenomenon opens the way to manufacture porous ceramics without the addition of pore generators, simplifying the process, and especially the thermal treatment.

Synthesis of DOPO‐Containing Melamine Flame Retardant and Its Effect on the Flame‐Retardant Properties of Waterborne Polyurethane

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 3, January 15, 2026.
DOPO‐containing melamine flame retardants improve the flame retardancy, droplet resistance and mechanical properties of WPU. ABSTRACT To improve the flame retardancy of waterborne polyurethane (WPU), two novel DOPO‐containing melamine‐based flame retardants were synthesized by combining Schiff bases (derived from p‐hydroxybenzaldehyde ...
