Kinetic Insights into Precursor‐Assisted Soft Sphere Close Packing Revealed by In Situ GISAXS with Implications for Gas Sensing

open access: yesAdvanced Functional Materials, EarlyView.
The versatile precursor‐assisted soft sphere close packing during slot‐die coating is investigated with in situ X‐ray scattering. The soft crystallization pathways towards a close packing involve multistep structural transitions such as surface nucleation, in‐plane, and out‐of‐plane crystallization.

On the morphology and corrosion behavior of Ni nanostructures electrodeposited in the presence of different surfactants [PDF]

open access: yesشیمی کاربردی روز, 2018
In this work, Ni nano structures with different surface morphology have been electrodeposited from the Waths bath using direct current (DC) and pulsed reverse current (PRC) techniques in the presence of three types of surfactants. CTAB, SDS, and Triton x-

Robust Superhydrophobic Brass Mesh with Electrodeposited Hydroxyapatite Coating for Versatile Applications

open access: yesMolecules, 2022
A robust superhydrophobic brass mesh was fabricated based on a low-energy surface and a roughness on the nano/micro-meter scale. It was carried out by the forming of hydroxyapatite (HP) coatings on its surface through a constant current electro ...

Biomaterial Strategies for Targeted Intracellular Delivery to Phagocytes

open access: yesAdvanced Functional Materials, EarlyView.
Phagocytes are essential to a functional immune system, and their behavior defines disease outcomes. Engineered particles offer a strategic opportunity to target phagocytes, harnessing inflammatory modulation in disease. By tuning features like size, shape, and surface, these systems can modulate immune responses and improve targeted treatment for a ...

High‐Density Boron Nitride Nanotube Composites via Surfactant‐Stabilized Lyotropic Liquid Crystals for Enhanced Space Radiation Shielding

open access: yesAdvanced Functional Materials, EarlyView.
High‐density BNNT films, enabling mechanical robustness and high space radiation shielding effectiveness, are fabricated using surfactant‐stabilized BNNT liquid crystal. Simulations indicate that a 50 g cm−2 BNNT film can reduce radiation exposure by 56% compared to zero shielding, potentially doubling the duration of astronaut missions on the lunar ...

Self‐Immolative Activatable Nanoassembly toward Immuno‐Photodynamic Therapy in TME

open access: yesAdvanced Functional Materials, EarlyView.
A quinone methide‐gated, self‐immolative, H2O2‐responsive nano‐photosensitizer (Pyz/PS) is developed for targeted immuno‐photodynamic therapy. Pyz/PS selectively activates within tumor microenvironments, restores photosensitizer activity, generates ROS, and depletes intracellular GSH, enhancing oxidative stress.

Advancing Electrochemical Nitrate Reduction: Overcoming Rate‐Limiting Bottlenecks with Copper/Cobalt Catalysts

open access: yesAdvanced Functional Materials, EarlyView.
This paper synthesizes CuO@CuCo2O4 catalysts via an emulsion hydrothermal method. Among them, CuCuCo2O4 perfectly inherits the advantages of CuO and Co3O4 and successfully connects the reactions in series. During the electrolysis process, CuO is reduced to Cu.
