“…Table 1 lists the frequency shift ∆ν and the number of guest molecules calculated thereof according to the formula: [41][42][43] In order to compare the pre-and post-hydrogenated dendrimers with regard to their capacity to incorporate guests, the number of host molecules in the coating must be known. Whereas this number can be calculated for the hydrogenated forms, it is unavailable for the non-hydrogenated species because their diameter d is not known with certainty.…”

Different generation polyphenylene dendrimers possessing eight diphenylacetylene units in the dendritic scaffold between the layers of the first and second generation have been synthesized by using a new p-phenylene ethynylene-functionalized tetraphenylcyclopentadienone branching unit. The heterogeneous hydrogenation of the embedded triple bonds in the final dendrimers was successfully performed via heterogeneous catalysis. Moreover a "softening" effect of the dendritic structure in consequence of the hydrogenation is observed, allowing for the first time the investigation of this effect upon size, shape, and intramolecular voids in the case of similar dendrimer pairs. Quartz microbalance studies revealed that upon hydrogenation the capacity in host uptake is decreased allowing the incorporation of a lower number of guest molecules compared to the parent materials.

An electrochemical amperometric ethylene sensor with solid polymer electrolyte (SPE) and semi-planar three electrode topology involving a working, pseudoreference, and counter electrode is presented. The polymer electrolyte is based on the ionic liquid 1-butyl 3-methylimidazolium bis(trifluoromethylsulfonyl)imide [BMIM][NTf2] immobilized in a poly(vinylidene fluoride) matrix. An innovative aerosol-jet printing technique was used to deposit the gold working electrode (WE) on the solid polymer electrolyte layer to make a unique electrochemical active SPE/WE interface. The analyte, gaseous ethylene, was detected by oxidation at 800 mV vs. the platinum pseudoreference electrode. The sensor parameters such as sensitivity, response/recovery time, repeatability, hysteresis, and limits of detection and quantification were determined and their relation to the morphology and microstructure of the SPE/WE interface examined. The use of additive printing techniques for sensor preparation demonstrates the potential of polymer electrolytes with respect to the mass production of printed electrochemical gas sensors.

“…Hence, there is a need for simple, compact, inexpensive, portable, and reliable ethylene sensors that could be used parallel in controlling ethylene concentration systems. The technologies that have been commonly used include gas chromatography [3], optical sensors [4], colorimetric sensors [5], amperometric sensors [6], photoluminescence sensors [7], gravimetric sensors [8], and chemoresistive and capacitive sensors [9,10]. From technologies has been mentioned, chemoresistive can meet criteria desired One of material frequently used as sensitive layer in gas sensor is tin oxide (SnO2), because of its properties including fast-response speed, high chemical stability, and prominent selectivity.…”

Abstract. Ethylene gas is a gas naturally released by fruits. The maturity level of these fruits could be predicted from the amount of ethylene around them. To maintain the freshness of these fruits, the concentrations of surrounding ethylene need to be monitored. Therefore, suitable gas sensor ethylene were still in progress to get good respond. In this paper systhesis of pure SnO2 nanoparticle from SnCl2.2H2O and water solution in precipitation method was held. The tin oxide powder was obtained in good distribution with nanoparticle size. This nanoparticle powder was formed into thick film, using ethylene glycol as solvant. To observe this sensor characteristics, several test was held in various conditions. Gas testing used pure ethylene gas show better respond at higher than room temperature but recovery time still unsatisfying.
