Balancing Hydrophobicity and Hydrophilicity: Dual Filler‐Engineered Proton Exchange Membranes for Durable, High‐Power Fuel Cells

Advanced Functional Materials, EarlyView.
Polarity‐matched Zr–MOFs program Nafion's nanoscale morphology during solution casting. Hydrophilic UiO‐66 preserves hydrated pathways, while hydrophobic UiO‐67 increases the proton hopping sites by densifying ionic clusters. Combining both fillers yields a membrane that delivers 176 mS cm−1 conductivity, reaches 1.46 W cm−2 under 200 kPa, and triples ...

Ubiquitin Connects with Planar Cell Polarity [PDF]

Cell, 2009
Planar cell polarity (PCP) regulates the orientation of cells in epithelia and of mesenchymal cells during gastrulation. In this issue, Narimatsu et al. (2009) report that the Smurf E3 ubiquitin ligases are required for localized protein degradation of a core PCP factor to generate cellular asymmetry.

Planar polarity in the ciliated epidermis of Xenopus embryos

, 1993
The coordinated orientation of ciliary beat in the larval epidermis of amphibians, evident in an organized streamline pattern, suggests a planar polarity of the epithelium, i.e., a polarity within the plane of the cell sheet.

Long-term preservation of planar cell polarity in reversed tracheal epithelium

Respiratory Research, 2018
Background Planar cell polarity (PCP) coordinates the patterning and orientation of cells and their structures along tissue planes, and although its acquisition during the formation of airway epithelium has been described, the mechanisms for its ...

Cell Flow Reorients the Axis of Planar Polarity in the Wing Epithelium of Drosophila [PDF]

, 2010
SummaryPlanar cell polarity (PCP) proteins form polarized cortical domains that govern polarity of external structures such as hairs and cilia in both vertebrate and invertebrate epithelia.

Load Distributing Metamaterials Via Discrete Optimization

Advanced Functional Materials, EarlyView.
Mechanical metamaterials are computationally optimized to homogenize transmitted forces by minimizing the spread of reaction forces. The resulting architectures transform localized loading into broader, more uniform force distributions and experimentally demonstrate robust load spreading under quasi‐static and impact loading.

Cellular interpretation of the long-range gradient of Four-jointed activity in the Drosophila wing

eLife, 2015
To understand how long-range patterning gradients are interpreted at the cellular level, we investigate how a gradient of expression of the Four-jointed kinase specifies planar polarised distributions of the cadherins Fat and Dachsous in the Drosophila ...

Licensing german negative polarity items in LTAG [PDF]

, 2008
Our paper aims at capturing the distribution of negative polarity items (NPIs) within lexicalized Tree Adjoining Grammar (LTAG). The condition under which an NPI can occur in a sentence is for it to be in the scope of a negation with no quantifiers ...
