Nanotherapies for Atherosclerosis: Targeting, Catalysis, and Energy Transduction

open access: yesAdvanced Healthcare Materials, EarlyView.
Atherosclerosis management is hindered by poor drug targeting and plaque heterogeneity. Nanotechnology overcomes these barriers via three core strategies: (1) target‐engineered nanocarriers that achieve lesion‐specific precision via ligand modification, biomimetic camouflage, stimuli‐responsive release, and self‐propelling nanomotors; (2) catalytic ...

Plasmonic Enhancement of Fluorescence and Protein Dynamics in Living Mammalian Cells

open access: yesAdvanced Materials, EarlyView.
This study demonstrates plasmonic enhancement of the function of fluorescent voltage sensing proteins (genetically encoded voltage indicators, (GEVIs), QuasAr6) in live mammalian cells. Coupling to plasmonic nanoparticles does not just increase fluorescence, but influences the protein photocycle, creating a hybrid sensor with its response speed to ...

Effect of Cladding Failure on FCCI Layer and Fission Product Behavior

open access: yesYuanzineng kexue jishu
Nuclear fuel rods are the first barrier preventing the release of fission products to the environment in the operation of nuclear power plants. Zirconium alloys are favored for their advantages, such as a low neutron absorption cross-section, excellent ...

Role of Liquid Composition in the Transient Liquid Assisted Growth of Superconducting YBa2Cu3O7‐δ Films

open access: yesAdvanced Materials, EarlyView.
The Y supersaturation in the [Ba‐Cu(I/II)‐O] transient liquid composition is the driving force toward YBCO nucleation and growth in TLAG. Tuning the initial (Ba:Cu) molar ratio in the ink composition determines the YBCO epitaxial nucleation through supersaturation control.

Alkaline Leaching: A Facile Surface Activation Strategy to Improve the Reactivity of Air Electrodes for Solid Oxide Fuel Cells

open access: yesAdvanced Materials, EarlyView.
This study shows that alkaline leaching of PrBa0.8Ca0.2Co2O5+δ under anodic bias selectively removes Ba and Ca, forming a cobalt‐rich and amorphous layer. The modified surface significantly boosts ORR activity, offering a simple and effective strategy to improve electrochemical device performance.
