High proton conductivity at low relative humidity in an anionic Fe-based metal-organic framework

A metal-organic framework, termed VNU-15 (VNU = Vietnam National University), was synthesized and subsequent detailed structural analysis revealed that the crystalline structure adopted the fob topology. Due to integrated sulphate ligands accompanied by hydrogen-bonded dimethylammonium ions that lined the pore channels of VNU-15, the proton conductivity of this material reached 2.90 × 10-2 S cm-1 at 95°C and 60% relative humidity. Remarkably, the high proton conductivity of VNU-15 was maintained under these conditions, without any appreciable loss, for 40 h.

Piezo-resistive and thermo-resistance effects of highly-aligned CNT based macrostructures

Recent advances in assembling Carbon NanoTubes (CNTs) into macrostructures with outstanding properties, such as high tensile strength, high conductivity and porosity, and strong corrosive resistance, have underpinned potentially novel applications. For example, in advanced electronics, bioengineering and nanomechanics. This paper focuses on the development of (i) the piezoresistive polydimethylsiloxane-CNT (PDMS-CNT) composite membrane, and (ii) the thermo-resistive CNT hotwire using a technique of producing highly aligned CNT yarns and films. Our experimental results show that while PDMS-CNT films possess an outperformed gauge factor (10.7) compared with ones of CNT films in recent publications and several metals, a clear linear relationship of the resistance versus the temperature for a hotwire using CNT yarn is observed. Hence, the work supplies valuable evidence in the use of CNT films and yarns in several potential applications as thermal sensing elements and anemo...
