Rough and Tough: How Particle Surface Roughness Affects Liquid Marble Formation and Stability

open access: yesAdvanced Science, EarlyView.
This study investigates the influence of particle surface roughness on the formation and stability of liquid marbles using well‐defined colloidal supraparticles as model systems. Increasing surface roughness enhances the interfacial contact angle, improves mechanical stability by increasing deformation resistance upon impact, and enables liquid marble ...

Attenuated Nuclear Tension Regulates Progerin‐Induced Mechanosensitive Nuclear Wrinkling and Chromatin Remodeling

open access: yesAdvanced Science, EarlyView.
The premature aging‐related progerin leads to defective nuclear morphology and is associated with disrupted molecular coupling between the extranuclear cytoskeleton and lamin‐associated nuclear envelope. It is discovered that progerin expression reduces nuclear tension, forms nuclear wrinkling, and enhances chromatin dynamics, thereby regulating ...

Second Order Phase Transition and Universality of Self-Buckled Elastic Slender Columns

open access: yes, 2019
Self-buckling is an interesting phenomenon that is easily found around us, either in nature or in objects made by human. Palm fronds which initially directed upward when they were short and turned into bending after appreciably longer is an example of ...

Oxygen Vacancy Defect Engineering for Transverse Thermoelectric Enhancement: a Novel Extrinsic Pathway beyond Intrinsic Approaches

open access: yesAdvanced Science, EarlyView.
Transverse thermoelectric (TE) technology gains increasing attention as it enables efficient power generation within a single TE element and eliminates junctions. This study enhances transverse thermopower in polycrystalline Sr3YCo4O10‐δ through oxygen vacancy defect engineering, utilizing the anomalous Nernst effect to improve TE efficiency.
