A new porous MOF, Zn(TBC)2·{guest}, is synthesized and studied by the single crystallography, N2 isothermal adsorption and GC separation of CO2 from air. This MOF shows large hysteresis on N2 adsorption at 77 K up to a P/Po of 0.9, which arises from the unique zig-zag channel structures of the framework. The MOF shows promising separation ability for CO2 from air. © 2012 The Royal Society of Chemistry.

Critical Reviews in Environmental Science and Technology | Year: 2013

Human activities have affected the global environmental system, resulting in drastic problems such as pollutants control either in solid, liquid or gas forms. The authors provide a thorough review on this pollution control topic covering from traditional decontamination processes, traditional materials used in these processes, to current status of nanomaterials, especially nanomaterial-based membranes that are used. An effort on the state-or-art works on metal-organic frameworks based membranes for gas separation is emphasized also in this review. © 2013 Taylor and Francis Group, LLC.

This review provides a comprehensive assessment of recently improved carbon dioxide (CO2) separation and capture systems, used in power plants and other industrial processes. Different approaches for CO2 capture are pre-combustion, post-combustion capture, and oxy-combustion systems, which are reviewed, along with their advantages and disadvantages. New technologies and prospective "breakthrough technologies", for instance: novel solvents, sorbents, and membranes for gas separation are examined. Other technologies including chemical looping technology (reaction between metal oxides and fuels, creating metal particles, carbon dioxide, and water vapor) and cryogenic separation processes (based on different phase change temperatures for various gases to separate them) are reviewed as well. Furthermore, the major CO2 separation technologies, such as absorption (using a liquid solvent to absorb the CO2), adsorption (using solid materials with surface affinity to CO2 molecules), and membranes (using a thin film to selectively permeate gases) are extensively discussed, though issues and technologies related to CO2 transport and storage are not considered in this paper. © 2013 The Royal Society of Chemistry.

Patent
Santa Fe Science and Technology, Inc. | Date: 2010-03-22

The present invention includes the use of conducting polymers as sensors in distributed sensing systems, as sensors and operating elements in multifunctional devices, and for conducting-polymer based multifunctional sensing fabrics suitable for monitoring humidity, breath, heart rate, blood (location of wounds), blood pressure, skin temperature, weight and movement, in a wearable, electronic embedded sensor system, as examples. A fabric comprising conducting polyaniline fibers that can be used to distribute energy for resistive heating as well as for sensing the fabric temperature is described as an example of a multifunctional sensing fabric.
