Engineering Morphological Anisotropy to Control the In Vivo Transport Dynamics, Clearance, and Biodistribution of Silica Nanocarriers

open access: yesAdvanced Science, EarlyView.
Morphological anisotropy directs the in vivo transport under physiological flow and clearance of silica nanocarriers. Increasing anisotropy reduces cellular uptake, suppresses hepatic and splenic sequestration, and prolongs systemic circulation by steering particles toward the central flow core.

Separation of microalgae suspension using rotating-disk dynamic microfilter

open access: yes, 2013
碩士本研究以旋轉盤薄膜微過濾進行微藻懸浮液之分離,提升微藻之採收與分離效率。利用旋轉盤造成之高剪切力降低濾餅之生成與過濾分離。以實驗與理論分析並行,探討旋轉盤轉速、進料速度與透膜壓差對過濾濾速、結垢阻力、濾餅性質與微藻粒徑大小之影響。 由實驗結果發現,對微藻粒子之阻擋率可達99.9 %,主要阻力來源為微藻形成之濾餅,而此濾餅具高壓縮性,壓縮係數為0.66。而增加進料速度與旋轉盤轉速,皆可提升膜面剪切力,掃除膜面濾餅與降低濾餅層厚度;故以低透膜壓差與高膜面剪切力之操作條件,即可得到最高的擬穩態濾速 ...

A pH‐Switchable Cerium Single‐Atom Enzyme for Peri‐Implantitis Therapy via JAK‐STAT Signaling Axis‐Mediated Macrophage Reprogramming

open access: yesAdvanced Science, EarlyView.
A pH‐switchable cerium single‐atom enzyme is developed for stage‐specific peri‐implantitis therapy. Acidic conditions trigger antibacterial peroxidase‐like activity, whereas neutral conditions activate an antioxidant superoxide dismutase ‐ and catalase ‐like enzymatic relay. This microenvironment‐adaptive catalytic strategy suppresses the IL‐6/JAK‐STAT

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

open access: yesAdvanced 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.
