Making Photoresponsive Metal–Organic Frameworks an Effective Class of Heterogeneous Photocatalyst

open access: yesAdvanced Functional Materials, EarlyView.
This review summarizes photoresponsive MOFs for photocatalytic applications, focusing on their capacity to enhance light harvesting, charge transfer, and surface reactions. While existing studies provide foundational insights, emerging characterization techniques enable a deeper understanding of photoresponsive MOFs.

The legal limbo of detention [PDF]

open access: yesForced Migration Review, 2009
Of the broad range of human rights violations suffered bystateless people, that of the right to be free from arbitrarydetention has received little attention. The extent and scale ofthe problem are not fully known.

Mechanisms enabling efficient fountain-flow supracellular migration [PDF]

open access: yesarXiv
In a prototypical mode of single-cell migration, retrograde cytoskeletal flow is mechanically coupled to the environment, propels the cell, and is sustained by an anterograde cytosolic flow of disassembled cytoskeletal components. Supracellular collectives also develop fountain-flows to migrate, but the opposing cellular streams interact with the ...

The Role of Fluorine‐Functionalized Organic Spacers for Defect Passivation and Low‐Dimensional Phase Formation in 3D MAPI Perovskite Solar Cells

open access: yesAdvanced Functional Materials, EarlyView.
Fluorine‐functionalized organic spacers (2F, 3F, 5F) are investigated to identify as optimal passivation agents for 3D MAPI perovskite solar cells (PSCs). The study highlights how altering fluorine positioning affects defect passivation, low‐dimensional phase (LDP) formation, and stability, emphasizing its role in molecular interactions and offering ...

Two-phase immiscible displacement of water by gas accounting for fines migration: analytical model for vertical equilibrium [PDF]

open access: yesarXiv
Fines migration during subterranean CO2 storage is considered as one of major contributors to formation damage and injectivity decline. The main formation damage mechanism by migrating fines is rock clogging by straining of particles in thin pore throats.
