“…Alcohol‐water mixtures have long been a topic of interest, [1] both in terms of fundamental research as well as in industrial contexts. For example, their different solvation properties affect the crystallization/dissolution of life‐essential amino acids, [2] and the survivability of various animal cells, [3,4] which is equally important in understanding biochemical (reaction) mechanisms, as it is in the area of beer‐ and wine‐production [5,6] . Various measurement techniques have been developed to probe the hydration of the hydrophobic moiety of molecules, which is one of the most important parameters in these contexts.…”

Dedicated to Wolfgang Schuhmann in honour of his 65 th birthdaySingle entity electrochemistry is employed to gain insights into ion solvation in solvent mixtures. To this end, the time required for the oxidation of individual indicator nanoparticles to sparingly soluble products is used to probe ionic diffusion, and hence gain new insights into the solvation properties of solvent mixtures. Herein, water-ethanol or water-methanol mixtures of different compositions are analyzed following this new approach, using silver nanoparticle oxidation in the presence of chloride and iodide as a complementary indicator reaction. For increasing concentrations of the bulkier alcohol molecules in the mixtures with water, an increasing content of alcohol molecules in the halide's solvation shell is detected by the observation of hindered halide diffusion. The extent of this solvent replacement is shown to scale with the charge density of the ions and the experimental results are rationalized with respect to literature-derived thermodynamic data, highlighting the ability of single entity electrochemistry to explore solvation in solvent mixtures.

“…Ethanol is a renewable resource which has great effect on food, transportation, and medical industries. On one hand, ethanol provides many conveniences for agricultural production and food processing; − however, on the other hand, abnormal ethanol concentrations can bring many hidden dangers, such as traffic accidents, health issues, industrial explosions, and medical accidents. − The same is true for other gases. Therefore, detection of gas concentration has a great significance. − So far, many sensors for detection of gas concentration have been studied extensively, especially ethanol sensors. − The response time of an ethanol sensor based on hierarchical SnO 2 /Zn 2 SnO 4 porous spheres is 2 s at 250 °C .…”

Ethanol sensors with ultrafast response and high sensitivity have attracted much attention to be applied to daily industrial production processes. In this work, graphene oxide–aniline (GOA) sensors are proposed to meet the requirements of detecting ethanol concentration. Graphene oxide is an outstanding material that has excellent electrical and thermal conductivity, large specific surface area, and high carrier mobility. Because of its special bonding reactions, GOA has advantages of good dispersibility, good electrical conductivity, insolubility in water, and strong plasticity. When testing ethanol concentration with sensors, there will be a lag time, which determines the sensitivity of the sensors. To the best of our knowledge, the GOA sensors in this work have the fastest response time, which is only 27 ms. The GOA ethanol sensors show a good ethanol sensing performance, including excellent sensitivity, cycle stability, and long-term stability.

“…Another alternative way to accurately and quickly identify ethanol is to use PCB-based microstrip-fed antennas. In wine production, monitoring of glucose and ethanol during the fermentation process is important to control the quality, specific taste and flavor of the wine [22]. Nowadays, sensor applications have become the matter of interest in both academia and industry.…”

In this work, a novel sensor based on printed circuit board (PCB) microstrip rectangular patch antenna is proposed to detect different ratios of ethanol alcohol in wines and isopropyl alcohol in disinfectants. The proposed sensor was designed by finite integration technique (FIT) based high-frequency electromagnetic solver (CST) and was fabricated by Proto Mat E33 machine. To implement the numerical investigations, dielectric properties of the samples were first measured by a dielectric probe kit then uploaded into the simulation program. Results showed a linear shifting in the resonant frequency of the sensor when the dielectric constant of the samples were changed due to different concentrations of ethanol alcohol and isopropyl alcohol. A good agreement was observed between the calculated and measured results, emphasizing the usability of dielectric behavior as an input sensing agent. It was concluded that the proposed sensor is viable for multipurpose chemical sensing applications.
