Connecting Droplet Adhesion with Sperm Kinematics: A New Paradigm in Sperm Quality Monitoring

open access: yesAdvanced Materials Interfaces, EarlyView.
This study demonstrates direct experimental evidence to establish a nonintuitive connection between the motion characteristics of self‐propelled sperm cells and their surface interaction. Simultaneous motion visualization and cantilever‐deflection‐based adhesion characterization reveal that sperm‐cell droplets with higher motility exhibit lower surface

Unveiling the Aging Effect at the Interface of N719 Dye‐Sensitized Solar Cells

open access: yesAdvanced Materials Interfaces, EarlyView.
Iodide is incorporated into the N719 layer through two mechanisms: the known ligand exchange of NCS with I and a second yet unknown mechanism which significantly blocks the charge regeneration process of the N719 dye contributing to the cell degradation.

AFM‐Based Functional Tomography – To Mill or Not to Mill, that is the Question!

open access: yesAdvanced Materials Interfaces, EarlyView.
Complex networks of conducting domain wall interfaces exist hidden underneath the surface of ferroelectric hexagonal manganites. It reveals the morphology and conductive properties directly by 3D tomographic atomic force microscopy. It correlates the measured surface level conductance with subsurface domain wall structure, and discuss the existence ...

Nanoengineering of Chitosan Sponges Via Atomic Layer Deposition of ZnO for Water Remediation Technologies

open access: yesAdvanced Materials Interfaces, EarlyView.
Chitosan sponges are modified with ZnO through atomic layer deposition (ALD) to enhance water remediation. Characterization reveals the growth of defective ZnO, which improves the water stability of the sponges. The material's effectiveness is demonstrated through the removal of Direct Blue 78 dye and the photocatalytic degradation of Naproxen ...
