Over 95% Optical Reflectance From Structurally Modulated All‐Biopolymer Multilayers

Advanced Materials, EarlyView.
A new dense–porous design turns ordinary polysaccharides into highly reflective photonic multilayers. Alternating dense pectin and porous cellulose nanofiber layers create strong refractive‐index contrast without inorganic or synthetic polymers, enabling nearly perfect visible reflection, high near‐infrared reflection, broadband metallic‐like colors ...

Tensor-valued diffusion MRI detects brain microstructural abnormalities in HIV infected individuals with cognitive impairment

Scientific Reports
Despite advancements, the prevalence of HIV-associated neurocognitive impairment remains at approximately 40%, attributed to factors like pre-cART (combination antiretroviral therapy) irreversible brain injury.

A Retinal Matrix Stiffening Model Reveals FAK‐Dependent Mechanotransduction in Pericytes Underlies Vascular Destabilization

Advanced Materials, EarlyView.
In this study, we show that retinal matrix stiffness is increased in diabetic mice. Using engineered human vascular models with controlled matrix stiffness, we demonstrate that stiffening activates focal adhesion kinase (FAK) signaling in pericytes, suppresses Notch signaling, and disrupts vascular morphology.

A Noninvasive Approach to Study Localized Forces in 3D Epithelia

Advanced Materials, EarlyView.
Epithelial morphogenesis depends on dynamic mechanical coupling between adhesion complexes and the cytoskeleton, yet its regulation in polarized 3D tissues remains elusive. We developed a noninvasive strategy using cell‐like elastic microbeads to quantify local forces in intact epithelia.

Binder‐Free Direct Ink Writing of Li6.4La3Zr1.4Ta0.6O12 Garnet Electrolytes for All‐Solid‐State Batteries

Advanced Materials Interfaces, EarlyView.
Polymer binders and thick pressed LLZTO pellets limit all‐solid‐state battery integration through grain‐boundary carbon and high ohmic losses. A binder‐free capillary suspension ink is direct‐ink‐written and sintered into 254 μm$\mu{\rm m}$, 95.8%‐dense Ta‐stabilized LLZTO with 17.3 mS cm−1$\text{cm}^{-1}$ bulk conductivity, enabling thinner ...

Life‐Like Ferrous Oxide Microspheres from Kombucha

Advanced Materials Interfaces, EarlyView.
Kombucha bacterial cellulose, sodium alginate, and ferrous nitrate self‐assemble into membrane‐enclosed iron oxide microspheres. These microspheres bud daughter vesicles, sustain 24‐h electrochemical oscillations, and filter theta‐band signals.

Statistical Mapping of Brain Connectivity

, 2007
Diffusion tensor MRI-imaging allows a unique opportunity to observe molecular mobility in living tissues. In brain white matter diffusion shows strong anisotropy and provides exquisite detail on nerve fiber tract organization.
