Long‐Term Hydrophilic, Anti‐Clotting, and Anti‐Fibrotic Dynamic Covalent Silicone‐Based Biomaterials
Advanced Healthcare Materials, EarlyView.Dynamic covalent crosslinking of a Schiff‐base silicone elastomer with hydrazide‐functionalized polymers is demonstrated to improve the long‐term hydrophilicity as well as the anti‐fouling and anti‐clotting properties of PDMS implants. The hydrazone‐functionalized material prevents hydrophobic recovery, resists clotting, and significantly reduces ...

Hydrodynamics, Mass and Heat Transferin Reactive Distillation
Al-Khawarizmi Engineering Journal, 2008 The ethyl acetate synthesis via heterogeneous reactive distillation is studied experimentally using ethanol and acetic acid. Three types of cation exchanging resins were used as catalysts: Zerolit 225, Zerolit 226 and Ambylite 400.

Distillation of reactive mixtures
, 1987 In this dissertation, the influence of equilibrium chemical reactions on vapor-liquid equilibrium and distillation processes is studied. The theory of reactive-phase diagrams for two-phase systems, in which the components undergo one equilibrium chemical

Conceptual design of single-feed hybrid reactive distillation columns
, 2005 It is well known that reactive distillation offers benefits by integrating distillation and reaction within a single unit. While there are procedures available for the synthesis of non-reactive distillation processes and of reaction-separation systems ...

Ferroelectric Quantum Dots for Retinomorphic In‐Sensor Computing
Advanced Materials, EarlyView.This work has provided a protocol for fabricating retinomorphic phototransistors by integrating ferroelectric ligands with quantum dots. The resulting device combines ferroelectricity, optical responsiveness, and low‐power operation to enable adaptive signal amplification and high recognition accuracy under low‐light conditions, while supporting ...

Understanding Nonlinear Dynamic Behavior of Reactive Distillation
, 2007 反應蒸餾塔是在單元設備裡結合反應與分離程序，藉此可提高某些化學反應系統的經濟效益。由於反應蒸餾具有多功(Multifunctional)的本質，這使得反應或分離原本的非線性特性更加複雜。因此相較於單一功能單元的動態，反應蒸餾塔之動態與控制行為較不明顯。本研究目的主要探討反應蒸餾塔非線性的動態行為，由於分離程序與化學反應的交互作用下，導致產品組成與操作變數之穩態增益出現變號(Sign Reversal)行為。以程序控制觀點來看，表示有右半平面的零位(RHP Zeros)的產生，也就是具有非最小相位的行為 ...
