Ultrafine Molybdenum Wire Braided Neurointerventional Implants: Bridging Biodegradability and Neurovascular Safety for Stroke Treatment

Advanced Science, EarlyView.
Molybdenum (Mo), with its unique strength, uniform corrosion, and radiopacity, enables innovative biodegradable implants for transformative stroke therapy. Abstract Neurovascular implants for stroke intervention face a critical dilemma: permanent devices (e.g., nitinol stents, platinum coils) often trigger chronic inflammation and recurrence, whereas ...

Design Method for Contra-Rotating Propellers for High-Speed Crafts: Revising the Original Lerbs Theory in a Modern Perspective

International Journal of Rotating Machinery, 2012
The main theoretical and numerical aspects of a design method for optimum contrar-rotating (CR) propellers for fast marine crafts are presented. We propose a reformulated version of a well-known design theory for contra-rotating propellers, by taking ...

A Pill That Prints‐An Ingestible Bioprinter for Non‐Invasive Structured Bioink Deposition

Advanced Science, EarlyView.
A first‐of‐a‐kind swallowable bioprinter performs in‐situ bioink deposition and patterning directly over disease sites without tethers, electronics, or invasive surgery. Combining magnetic guidance with near‐infrared triggering enables functionality within a small footprint.

Wide‐Flow Aerosol Jet Printing Enables High‐Throughput, Ultra‐Low Aspect Ratio Patterning

Advanced Science, EarlyView.
Wide‐flow aerosol jet printing (WF‐AJP) employs an anisotropic nozzle design to generate planar aerosol jets, enabling millimeter‐scale deposition of highly uniform, ultra‐low aspect ratio (<1:6000) films with substantially reduced anisotropy in functional performance.

T Cell Exhaustion and Dendritic Cell‐Mediated Tertiary Lymphoid Structures (TLSs) Modulation Affect Response to Neoadjuvant Chemoradiotherapy in Microsatellite Stable Rectal Cancer

Advanced Science, EarlyView.
Using multi‐omics analysis, this study demonstrates that immune characteristics of the tumor microenvironment, rather than mutational profiles, are more strongly correlated with treatment response. Specifically, early exhausted T cells and tertiary lymphoid structures regulation by LAMP3⁺ dendritic cells emerge as key predictors of favorable outcomes ...

Improving Interlayer Interactions in Proton Exchange Membrane Fuel Cell through Carbon Nanotube‐Based Catalyst Design

Advanced Science, EarlyView.
This review highlights how carbon nanotube (CNT)–based catalyst designs enhance proton exchange membrane fuel cell (PEMFC) performance by improving interlayer interactions. Vertically aligned CNTs facilitate water management, mass transfer, and electron conduction while promoting effective active sites and reducing interfacial resistance.

Free‐Volume Regulation Enables Significantly Enhanced Electrical Breakdown via Short‐Chain Molecular Spatial‐Positioning Intercalation into Poly(vinylidene fluoride)

Advanced Science, EarlyView.
An innovative molecular spatial‐positioning shimming strategy is developed to optimize the electrical properties of poly(vinylidene fluoride) (PVDF). By intercalating polyethylene wax (PE wax) short‐chain molecules into PVDF's free volume, the film achieves a significantly enhanced energy density of 32.67 J cm−3.

The Cut-Cell Method for the Conjugate Heat Transfer Topology Optimization of Turbulent Flows Using the “Think Discrete–Do Continuous” Adjoint

Energies
This paper presents a topology optimization (TopO) method for conjugate heat transfer (CHT), with turbulent flows. Topological changes are controlled by an artificial material distribution field (design variables), defined at the cells of a background ...
