Enhanced Mass Transport and Elevated Active Site Density for Highly Efficient Overall Water Splitting Over Delignification‐Engineered Carbonized Wood

open access: yesCarbon Energy, EarlyView.
Controlled delignification pretreatment tailors the hierarchical porous structure of wood to improve ion transport and create abundant anchoring sites for Ni/Ni(OH)2 catalysts. The optimized electrode shows enhanced mass transfer, increased active site density, and superior overall water‐splitting performance, demonstrating delignification as an ...

Connecting the dots: A narrative review of the relationship between heart failure and cognitive impairment

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1119-1131, April 2025.
Abstract Large clinical data underscore that heart failure is independently associated to an increased risk of negative cognitive outcome and dementia. Emerging evidence suggests that cerebral hypoperfusion, stemming from reduced cardiac output and vascular pathology, may contribute to the largely overlapping vascular dementia and Alzheimer's disease ...

Meta‐Virtuality: Strategies of Disembeddedness in Virtual Interiorities

open access: yesJournal of Interior Design, EarlyView., 2022
ABSTRACT To reclaim their seat in the rapidly growing market of virtual space, designers of the built environment can benefit from reevaluating theories that see the virtual as a mere extension/reflection of the physical. By claiming ontological autonomy from external worlds, the virtual is liberated from the hegemonic control of the physical.
