A note on the effect of surface contamination in water wave damping [PDF]

, 2000
Asymptotic formulas are derived for the effect of contamination on surface wave damping in a brimful circular cylinder; viscosity is assumed to be small and contamination is modelled through Marangoni elasticity with insoluble surfactant. It is seen that

Bio‐Inspired Gradient Coatings Enhance the Leading Edge Erosion Resistance of Wind Blades

Advanced Science, EarlyView.
Rain‐induced erosion of the wind turbine blade leading edge poses a critical challenge to maintenance and operation. Here, we propose a bio‐inspired approach for erosion protection utilising a platelet‐reinforced polyurethane coating with a graded through‐thickness architecture.

Blood Cell‐Camouflaged Liquid Metal Nanoconjugates Orchestrate Treg Depletion and STING‐Amplified Photothermal Immunity for Metastatic Triple‐Negative Breast Cancer Therapy

Advanced Science, EarlyView.
Whole‐blood biomimetic engineering transforms liquid metal nanoparticles into a tripartite immunotherapeutic platform that orchestrates regulatory T‐cell depletion, photothermal‐induced immunogenic cell death, and activation of the stimulator of interferon genes pathway.

Analysis and Experiment of Damping Characteristics of Multi-Hole Pressure Pulsation Attenuator

Machines
Aviation hydraulic systems operate under high pressure and large flow rates, which induce significant fluid pressure pulsations and hydraulic shocks in pipelines. These pulsations, exacerbated by complex external loads, can lead to excessive vibration stress, component damage, oil leakage, and compromised system safety.

A Multidimensional Engineering Strategy Reprograms Microglia via Targeted and Sustained‐Release Extracellular Vesicles for Spinal Cord Injury Repair

Advanced Science, EarlyView.
A multifunctional EV‐based nanoplatform (Ang‐TEVs@Gel) was engineered via preconditioning, surface targeting, and ROS‐responsive hydrogel encapsulation to reprogram microglia. This system restored autophagy via miR‐664a‐3p/PIK3CA axis, cleared myelin debris, resolved neuroinflammation, and promoted axon remyelination, ultimately achieving robust motor ...

Versatile Co‐Engineering of Immunogenic Cell Death‐Primed Dead Tumor Cell Bodies With Tumor‐Activated MnO2 for cGAS‐STING‐Potentiated Personalized Immunotherapy

Advanced Science, EarlyView.
DTBEI@CS@MnO2, fabricated via modular electrostatic co‐engineering and photothermal/photodynamic immunogenic cell death, specifically responds to the acidic and GSH‐rich tumor microenvironment. This triggers the release of DTBEI that provides tumor antigens, DNA, and DAMPs, as well as the generation of Mn2+, thereby synergistically potentiating cGAS ...

High‐Power Hybrid Nanogenerator With Multi‐Degree‐of‐Freedom Mechanical Coupling for Harvesting Water Wave Energy

Advanced Science, EarlyView.
A high‐power hybrid nanogenerator (HP‐HNG) with multi‐degree‐of‐freedom mechanical coupling is reported, integrating multi‐directional wave energy for output to achieve 1 + 1 > 2 energy harvesting. The HP‐HNG achieves a peak output power of 0.764 W, corresponding to a peak power density of 127.303 W m−3. At a wave frequency of 1 Hz, the HP‐HNG delivers

Iron‐Tannic Acid Hydrogel Mediated Mild Photothermal Therapy Combined With Ferroptosis Enhances Anti‐Tumor Immunity in Colorectal Cancer

Advanced Science, EarlyView.
An injectable gelatin‐based tannic acid–iron hydrogel with mild photothermal therapy could not only induce immunogenic cell death, but also elicit ferroptosis of both tumor cells and tumor‐associated macrophages, resulting in DC maturation, T‐cell infiltration and down‐regulation of ferroptosis‐sensitive M2‐type TAMs levels.

Improving Photometric Redshifts of Epoch of Reionization Galaxies: A New Empirical Transmission Curve with Neutral Hydrogen Damping Wing Lyα Absorption

The Astrophysical Journal Letters
We present a new analytical model for the attenuation to Epoch of Reionization (EoR) galaxies by proximate neutral hydrogen gas. Many galaxy spectra in the EoR taken by JWST have shown a flux deficit at wavelengths just redward of the Lyman break, and ...
