“…Other researchers have similarly produced limonene selective MIPs using common reagents and ratios (1:4:20 template-monomer-crosslinker) [ 143 , 144 ]. More pertinent with regard to this review however is the analysis by Völkle et al, in their study of limonene imprinting with different template-solvent ratios [ 145 ].…”

The selective sensing of gaseous target molecules is a challenge to analytical chemistry. Selectivity may be achieved in liquids by several different methods, but many of these are not suitable for gas-phase analysis. In this review, we will focus on molecular imprinting and its application in selective binding of volatile organic compounds and atmospheric pollutants in the gas phase. The vast majority of indexed publications describing molecularly imprinted polymers for gas sensors and vapour monitors have been analysed and categorised. Specific attention was then given to sensitivity, selectivity, and the challenges of imprinting these small volatile compounds. A distinction was made between porogen (solvent) imprinting and template imprinting for the discussion of different synthetic techniques, and the suitability of each to different applications. We conclude that porogen imprinting, synthesis in an excess of template, has great potential in gas capture technology and possibly in tandem with more typical template imprinting, but that the latter generally remains preferable for selective and sensitive detection of gaseous molecules. More generally, it is concluded that gas-phase applications of MIPs are an established science, capable of great selectivity and parts-per-trillion sensitivity. Improvements in the fields are likely to emerge by deviating from standards developed for MIP in liquids, but original methodologies generating exceptional results are already present in the literature.

“…The content of 17 volatile compounds was detected by the newly developed GC–MS method, and the results are detailed in Table 4 . D‐Limonene, a prominent aromatic compound found in citrus fruits (Wen et al., 2022 ), exhibited the highest content in both XHCP‐0Y and XHCP‐3Y samples, ranging from 42.62 to 78.36 mg/g. Following closely was γ‐terpinene, known for enhancing aroma, with a content ranging from 1.93 to 13.28 mg/g.…”

Xinhui Chenpi (XHCP) is a well‐known type of Chenpi (CP) widely used as both a Chinese herb and a food ingredient. While previous studies have explored how the quality of CP changes over time, there has been limited research specifically on XHCP. This study aims to assess the chemical components and quality of XHCP based on total flavonoid content (TF), antioxidant activity (AA), and color value (CV) at two stages: freshly harvested (XHCP‐0Y) and after 3 years of storage (XHCP‐3Y). Thirty‐eight common volatile compounds were identified, and the content of 17 compounds among them, nine nonvolatile compounds, which included one alkaloid (synephrine), three phenolic acids (PA, protocatechuic acid, vanillic acid, and ferulic acid), and five flavonoids (narirutin, hesperidin, sinensetin, nobiletin, and tangeretin), were firstly detected by the newly developed gas chromatograph–mass spectrometer (GC–MS) and ultra‐performance liquid chromatography (UPLC) methods. Compared to XHCP‐0Y, the content of 17 volatile compounds and synephrine decreased in XHCP‐3Y to varying degrees, while the content of PA, five flavonoids, TF, AA, and CV increased. The reduction of dryness caused by volatile compounds and the enhancement of efficacy related to PA, flavonoids, and AA suggested improved quality of XHCP after 3 years of storage. The methods developed in this study show promise for evaluating the quality of XHCP during the aging process.

“…Water scarcity is a paramount global challenge in the contemporary era, posing significant threats to both economic growth and ecosystem health [1][2][3][4] . The increasingly intricate challenges of providing sufficient and safe drinking water are compounded by climate change, as well as the pressures stemming from economic development and industrialization [5][6][7][8][9] . Both the public and industrial sectors consume substantial amounts of freshwater while concurrently generating corresponding wastewater.…”

Interfacial solar evaporation is a sustainable and effective method that uses solar energy to produce freshwater. As this technology continues to develop, the ability of interfacial solar evaporators to tolerate high salt concentrations and achieve stable evaporation has gradually improved. Some evaporators can even achieve complete separation of water and solutes, resulting in zero liquid discharge. Here, we discuss strategies for interfacial solar evaporators for treating high-salinity wastewater and achieving zero liquid discharge. We particularly focus on representative management strategies, including timely removal of salt crystals and prevention of salt deposition on photothermal materials. Additionally, we present three design ideas for evaporators, including the fundamental principles behind these strategies. Current challenges and future research opportunities are proposed.
