“…Moreover, the average value of its roughness was determined to be 33.3 nm by the Nano Scope Analysis software. 36,37 The phase purity and the crystallographic structure of the commercial 4A molecular sieve were analyzed through the Xray diffraction (XRD) technique, and the results are shown in Figure 2a. Its diffraction peaks agreed well with the corresponding standard card (JCPDS PDF #38-241).…”

A Ce 0.8 Gd 0.2 O 1.95 -based mixed potential type sensor attached with a commercially available Au paste sensing electrode material was fabricated to detect methanol. The optimum working temperature of the sensor was 545 °C, and the response value to 100 ppm methanol was −53 mV. The selectivity of the sensor was poor. The addition of a 4A molecular sieve filter layer and the method of pattern recognition were combined to improve it. Only gas molecules smaller than the pore diameter of the 4A molecular sieve were able to pass through the zeolite channel, and the selectivity coefficient of the sensor to methanol was improved by adding the filter layer. Meanwhile, there was an obvious distinction between the response and recovery times of the sensor toward methanol, ethanol, acetone, n-butanol, and n-pentanol. Next, the pattern recognition method was adopted. The relationship between the response value and the logarithm of gas concentration and the relationship between the maximum rate of the response process and the gas concentration were plotted separately. By comprehensively considering the two characteristic parameters of the response value and the maximum value of the differential response signal, the purpose of qualitative identification of gas types and quantitative analysis of gas concentrations was hopefully achieved.

“…[240] In order to meet the needs of breath analysis, the performance of traditional room temperature ammonia sensor is widely studied from different sensing mechanisms. [216,218,[241][242][243] For example, Liu's work provided a strategy for developing NH 3 sensors for highly selective NH 3 detection at the sub-ppm level of breath. [190] Organic acids were embedded into cross-linked PEGDA hydrogels by thiol-ene photochemistry to form the stable hydrogels.…”

Hydrogels, as the most typical elastomer materials with three-dimensional (3D) network structures, have attracted wide attention owing to their outstanding features in fields of sensitive stimulus response, low surface friction coefficient, good flexibility, and bio-compatibility. Because of numerous fresh polymer materials (or polymerization monomers), hydrogels with various structure diversities and excellent properties are emerging, and the development of hydrogels is very vigorous over the past decade. This review focuses on state-of-the-art advances, systematically reviews the recent progress on construction of novel hydrogels utilized several kinds of typical polymerization monomers, and explores the main chemical and physical cross-linking methods to develop the diversity of hydrogels. Following the aspects mentioned above, the classification and emerging applications of hydrogels, such as pH response, ionic response, electrical response, thermal response, biomolecular response, and gas response, are extensively summarized. Finally, this review is done with the promises and challenges for the future evolution of hydrogels and their biological applications.

“…Among the many known VOCs (e.g., ammonia, − nitrogen dioxide (NO 2 ), − hydrogen sulfide (H 2 S), , toluene, acetone, and formaldehyde), NO 2 is one of the most intensively targeted gases because it can directly damage human health at ppm levels; moreover, NO 2 is the cause of many environmental problems. To effectively monitor NO 2 gas, Jin et al demonstrated an ionotronic gas-sensing sticker (IGS) that showed particularly high selectivity for NO 2 and can be used as a wearable gas-sensing platform .…”
