The simple vinyl alkyl ethers are readily prepared from the β-bromo-ethyl ethers by the action of solid sodium hydroxide. Besides the vinyl ethers, the dialkyl ethers of diethylene glycol are formed in these reactions. β-Bromo-ethers are obtainable from the mono-ethers of ethylene glycol through the use of phosphorus tribromide. The constants of several vinyl ethers are given for the first time. The preparation of vinyl methyl ether, a gas at room temperature, and of vinyl n-butyl ether, b.p. 93.3 °C., is described.

The research aims were to construct an air-breathing paper-based microfluidic fuel cell (paper-based μ FC) and to evaluated it with different soft drinks to provide energy for their prospective use in portable devices as an emergency power source. First, in a half-cell configuration, cyclic voltammetry showed that glucose, maltose, and fructose had specific oxidation zones in the presence of platinum-ruthenium on carbon (PtRu/C) when they were individual. Still, when they were mixed, glucose was observed to be oxidized to a greater extent than fructose and maltose. After, when a paper-based μ FC was constructed, PtRu/C and platinum on carbon (Pt/C) were used as anode and cathode, the performance of this μ FC was mostly influenced by the concentration of glucose present in each soft drink, obtaining maximum power densities at room temperature of 0.061, 0.063, 0.060, and 0.073 mW cm − 2 for Coca Cola ® , Pepsi ® , Dr. Pepper ® , and 7up ® , respectively. Interestingly, when the soft drinks were cooled, the performance was increased up to 85%. Furthermore, a four-cell stack μ FC was constructed to demonstrate its usefulness as a possible power supply, obtaining a power density of 0.4 mW cm − 2 , using Coca Cola ® as fuel and air as oxidant. Together, the results of the present study indicate an alternative application of an μ FC using soft drinks as a backup source of energy in emergencies.

A Ce -doped La 0.9 MnO 3-δ sample was prepared by the Pechini route, consisting of a polymerization of citric acid and ethylene glycol, in order to prepare a phase with oxygen deficiency that can be used in fuel cell applications. To substitute a part of lanthanum by cerium, we added CeO 2 in excess to force it to react and diffuse in the perovskite. The Fourier Transformed infrared (FTIR) spectrum of the resin at 200°C has shown the formation of complex metals form and polymerized form of ethylene glycol. The X-ray diffraction (XRD) spectrum of the sample, calcined at 900°C, has revealed that the sample is mainly constituted by a deficient rhombohedra perovskite phase. The measurement of the ionic conductivity by complex impedance at room temperature has given a relatively high value, which opens up an opportunity for solid oxide fuel cell applications.
