Steady-state modeling of reactive distillation columns - doi: 10.4025/actascitechnol.v34i1.9535

open access: yesActa Scientiarum: Technology, 2011
An algorithm for the solution of the mathematical model featuring reactive distillation process in steady-state columns is analyzed. It has been presumed that each stage’s outlet streams in the model were in phase equilibrium conditions and that chemical

Piezoelectric Surface Charge and Dynamic Stimulation Synergize to Promote Cardiac Myoblast Alignment and Maturation

open access: yesAdvanced Healthcare Materials, EarlyView.
Surface polarization of PVDF films combined with mechanical stimulation generates piezoelectric electrical cues that modulate cardiomyoblast behaviour. Non‐poled and poled PVDF substrates provide distinct electroactive microenvironments influencing cell adhesion, proliferation, and differentiation.

Tuning the Testicular Microenvironment for Enhancing Human Sertoli Cells Maturation and Functionality In Vitro

open access: yesAdvanced Healthcare Materials, EarlyView.
An in vitro testicular model is developed by generating connective tissue equivalents from human dermal fibroblast‐derived microtissues and coupling them with human Sertoli cells or human Sertoli cell spheroids. This engineered microenvironment supports Sertoli cell maturation and functionality, providing a promising platform for studying human ...

Conceptual Design of n-Butyl Acetate Synthesis Process by Reactive Distillation Using Residue Curve Maps [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 2018
Residue curve maps are a powerful tool for the preliminary design of Reactive Distillation (RD). In this study, residue curve maps of the n-butyl acetate synthesis reaction were calculated based on the Langmuir–Hinshelwood–Hougen–Watson kinetic and ...

3D‐Printed Piezoionic/Bioelectronic Hydrogel for Electro‐Metabolic Regulation of Osteogenic Differentiation

open access: yesAdvanced Healthcare Materials, EarlyView.
A 3D‐printed piezoionic GPMx hydrogel enables stable electromechanical signal generation under mechanical loading, exhibiting long‐term durability and low fatigue. As a bioactive patch, it restores endogenous bioelectricity to stimulate osteogenesis via Ca2+ influx and mitochondrial activation, while simultaneously enabling label‐free alkaline ...

Stationary states in reactive distillation columns

open access: yesТонкие химические технологии, 2012
An approach to the analysis of stationary reactive distillation states multiplicity is considered with methyl-tert-butyl ether as an example. Three steady states of the process corresponding to different values of the product yield are revealed by means ...

Feasibility of Ternary Reactive Distillation Systems: Decomposition Reaction

open access: yes, 2007
摘要 反應蒸餾程序具有經濟上的優勢,特別在可逆反應或是共沸現象出現時。但是迭代設計過程非常耗時,透過可行性分析能檢查程序是否可行,藉由刪除不可行的設計,化學工程設計師將能節省大量嘗試錯誤的時間,但是反應蒸餾塔的捷徑式設計與可行性分析至目前為止仍尚未發展完全。Guo等人曾對反應性三成份共沸系統可行性進行系統化分析,方法為Lee等人所發展的反應差異點圖形化逐板運算。此法有兩個限制,一為需要正向反應,二為產品能由蒸餾或是反應蒸餾達到。在本工作中發現可行性分析方法可透過容許逆反應來增強,給出較正確的可行性預測。
