Development of electrorheological chip and conducting polymer-based sensor

Xianzhou ZHANG, Weihua LI, Weijia WEN, Yanzhe WU, Gordon WALLACE,

Frontiers of Mechanical Engineering 2009, Volume 4, Issue 4,   Pages 393-396 doi: 10.1007/s11465-009-0043-8

Abstract: development of an integrated sensor using two types of smart materials: electrorheological (ER) fluids and conductingThe response signals of the CP sensor were recorded, and its properties were analyzed.When the vibration frequency is larger than 20Hz, the CP sensor can hardly detect the displacementThus, the upper limit frequency that the CP sensor can detect is about 20Hz.

Overcoming the challenges of conducting translational research in cell therapy

Sowmya Viswanathan, Armand Keating

Frontiers of Medicine 2011, Volume 5, Issue 4,   Pages 333-335 doi: 10.1007/s11684-011-0166-2

Abstract: Cell therapy holds promise in addressing a number of unmet medical needs but despite its considerable impetus, faces numerous challenges including support for translational research in this area. Here, we examine the challenges confronting cell therapy research including the limited funding available for translational research partly due to the uncompetitive nature of required validation studies in cell therapy that of necessity are not hypothesis-driven. Other issues include lack of standardization of definitions of cell products, uncertainty regarding optimum preclinical animal models, duplication of efforts to secure regulatory approval and a lack of uniformity of nomenclature for some cell products. Nonetheless, several initiatives to address all of these issues are underway.

Keywords： stem cells     clinical trials     funding     animal models     standardization     common definitions

Microfluidic dual loops reactor for conducting a multistep reaction

Si Hyung Jin, Jae-Hoon Jung, Seong-Geun Jeong, Jongmin Kim, Tae Jung Park, Chang-Soo Lee

Frontiers of Chemical Science and Engineering 2018, Volume 12, Issue 2,   Pages 239-246 doi: 10.1007/s11705-017-1680-9

Abstract: Precise control of each individual reaction that constitutes a multistep reaction must be performed to obtain the desired reaction product efficiently. In this work, we present a microfluidic dual loops reactor that enables multistep reaction by integrating two identical loop reactors. Specifically, reactants A and B are synthesized in the first loop reactor and transferred to the second loop reactor to synthesize with reactant C to form the final product. These individual reactions have nano-liter volumes and are carried out in a stepwise manner in each reactor without any cross-contamination issue. To precisely control the mixing efficiency in each loop reactor, we investigate the operating pressure and the operating frequency on the mixing valves for rotary mixing. This microfluidic dual loops reactor is integrated with several valves to realize the fully automated unit operation of a multistep reaction, such as metering the reactants, rotary mixing, transportation, and collecting the product. For proof of concept, CdSeZn nanoparticles are successfully synthesized in a microfluidic dual loops reactor through a fully automated multistep reaction. Taking all of these features together, this microfluidic dual loops reactor is a general microfluidic screening platform that can synthesize various materials through a multistep reaction.

Construction of interfacial dynamic bonds for high performance lignin/polymer biocomposites

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 10,   Pages 1372-1388 doi: 10.1007/s11705-023-2302-3

Abstract: The development of lignin/polymer biocomposites can promote the high value utilization of lignin andHowever, the weak interfacial interaction between industrial lignin and polymer induces poor compatibilityand serious agglomeration in polymer owing to the strong intermolecular force of lignin.As such, it is extremely difficult to prepare high performance lignin/polymer biocomposites.The lignin-modified polymer composites achieved simultaneously enhanced strength and toughness.
