Thermally Modulated Metasurface Sensor for Dynamic and Time‐Resolved Isolation of Extracellular Vesicles

open access: yesAdvanced Materials, EarlyView.
A thermally adaptive plasmonic metasurface, functionalized with poly(N‐isopropylacrylamide) (PNIPAM) and anti‐CD63 antibodies, enables precise, on‐demand capture and release of extracellular vesicles (EVs). Delivering high recovery, improved purity, and intact vesicle structure, the platform offers a versatile, label‐free solution for real‐time EV ...

Hierarchically Engineered Multi‐Enzyme Nanoreactors for in vitro Drug Biosynthesis and Pathway Transplantation Into Cells

open access: yesAdvanced Materials, EarlyView.
A hierarchically structured metal–organic framework (eMIL) is shown to host the complete six‐enzyme biosynthesis pathway for the anti‐cancer pigment violacein, reshaping reaction dynamics and multiplying in vitro yields. eMIL nanoreactors deliver this reconstituted bacterial multi‐protein system into mammalian cells, where cell‐derived substrates and ...

Bubble Formation Control: Fabrication of Centimeter‐Sized Tissue‐Like Constructs by Catalase‐Coated Oxygen‐Releasing Hydrogel

open access: yesAdvanced Materials, EarlyView.
Oxygen‐releasing hydrogels are widely used to support cell survival in 3D cultures and to promote wound healing. However, incorporating catalase to convert H2O2 into O2 often generates additional oxygen bubbles, leading to material instability which rarely addressed.

Reactive distillation - a matter of combination: a theses on the reactive distillation unit operation

open access: yes, 1998
Reactive distillation is the combined unit operation of a chemical reaction with simultaneous distillation. Reactive distillation especially suits those reactions where reaction equilibrium limits the conversion.

AI–Guided 4D Printing of Carnivorous Plants–Inspired Microneedles for Accelerated Wound Healing

open access: yesAdvanced Materials, EarlyView.
This work presents an artificial intelligence (AI)‐guided 4D‐printed microneedle platform inspired by carnivorous plants for wound healing. A thermo‐responsive shape memory polymer enables body temperature–triggered self‐coiling for autonomous wound closure.

Synthesis of Reactive Distillation Column Design by MINLP Optimization

open access: yes, 2007
本研究提出一個以逐層式模式為基礎之完整反應蒸餾系統設計。 一般在研究反應蒸餾設計時,部分的結構變數往往需要靠經驗或直覺來決定、 而操作變數則由標準的最適化技術來求得。 本文將以價格考量所有變數,建立以低廉價格為取向之目標函數, 將所有變數納入目標函數中。 因此,本研究提出一個針對反應性蒸餾塔設計方法,能對所有結構變數及操作變數 作同時最適化的階層式模式。 將處理反應性蒸餾問題的階層式模式整合成一個混合整數非線性最適化問題, 其中同時考慮原物料成本、操作成本、投資成本 ...

Phase‐Pure and Size‐Tunable Tin Halide Perovskite Quantum Dots

open access: yesAdvanced Materials, EarlyView.
A trioctylphosphine oxide modulated protocol allows for the synthesis and study of the optical properties of a broad library of tin halide perovskite quantum dots across multiple A‐ and X‐site compositions with precise size tuning while eliminating unwanted 2D phases.
