Cataluminescence (CTL) sensors are among the most simple, inexpensive, sensitive, and selective tools for gas sensing. This study presented a highly efficient and selective CTL sensor system based on mesoporous SiO2 nanomicrospheres for the quick and sensitive analysis of isobutyraldehyde. Furthermore, its response intensity was 12.7 times higher than that of a nonmesoporous SiO2-based sensor. The constructed CTL sensor exhibited a good linear range (R2 = 0.997) for detecting isobutyraldehyde, spanning 3.11–311 ppm, with a low detection limit of 1.1 ppm. This enabled successful analysis of trace isobutyraldehyde in real samples. Finally, the CTL mechanism of this sensor was further explored. This study presents an approach for the quality detection of an important volatile organic compound, isobutyraldehyde, by a mesoporous-based CTL sensor.

Isobutyraldehyde is a harmful gas that poses a threat to both environment and human health. Therefore, it is essential to develop a highly selective, sensitive, and efficient sensor that can rapidly detect isobutyraldehyde traces. In this study, a cataluminescence gas sensor for isobutyraldehyde detection is developed utilizing porous aluminum nitrite. This sensor has a rapid response time and exhibits notable selectivity, stability, and sensitivity to isobutyraldehyde. The sensor operated effectively over a broad linear range of 0.776–310 ppm and achieved a detection limit of 0.155 ppm with a signal-to-noise ratio of 3. When applied to isobutyraldehyde detection in real samples, the developed sensor achieved recoveries in the range of 79.0–96.8 % with relative standard deviations (RSDs) of 4.6–8.7 %. The sensing mechanism was validated through density functional theory and gas chromatography–mass spectrometry. The sensor demonstrated excellent sensing properties, including enhanced sensitivity, selectivity, and stability, indicating considerable potential for trace isobutyraldehyde detection. Furthermore, it shows promise as an effective candidate for detecting other gaseous contaminants.

A simple, rapid, and reliable method for detecting harmful gases is urgently required in environmental security fields. In this study, a highly effective cataluminescence sensor based on SiO 2 /MIL-53(Al) composites was developed to detect trace isobutylaldehyde. The sensor was designed using isobutylaldehyde to generate an interesting cataluminescence phenomenon in SiO 2 /MIL-53(Al). Under optimized conditions, a positive linear relationship was observed between the signal intensity of the cataluminescence and isobutylaldehyde concentration. The isobutylaldehyde concentration range of 1.55–310 ppm responded well to the sensing test, with an excellent correlation coefficient of 0.9996. The minimum detectable concentration signal-to-noise ratio ( S/N = 3) was found to be 0.49 ppm. In addition, the sensor was effectively utilized for analyzing trace isobutylaldehyde; the analysis resulted in recoveries ranging from 83.4% to 105%, with relative standard deviations ( RSDs ) of 4.8% to 9.4%. Furthermore, the mechanism of cataluminescence between SiO 2 /MIL-53(Al) and isobutylaldehyde was explored using GC–MS analysis and density functional theory. We expect that this cataluminescence methodology will provide an approach for the environmental monitoring of isobutylaldehyde.

A highly sensitive and selective sensor for isobutyraldehyde (IBD) is demonstrated based on intensive cataluminescence (CTL) emission from the surface of nanosized Sm2O3 particles. The characteristics and optimum conditions for the CTL sensor, including the working temperature, wavelength, and flow rate, were investigated in detail. Under the optimized experimental conditions, the CTL intensity varied linearly with the concentration of IBD, in the two-order-of-magnitude range of 0.015–3.9 μg/mL, with a correlation coefficient (r) of 0.99991 and a limit of detection (LOD), at a signal-to-noise ratio (S/N = 3) of 4.6 ng/mL. The sensor was quite specific: butyraldehyde, methanol, ethanol, acetone, formaldehyde, acetaldehyde, benzene, ethylbenzene, and cumene could not produce significant CTL intensities; specifically, butyraldehyde, ethanol, acetone, and acetaldehyde produced low CTL intensities, with values that were 3.8%, 2.8%, 0.60%, and 0.57% that of IBD. As a test of sensor stability, we found that the relative standard deviation (RSD) of 30 measurements of the CTL at an IBD concentration of 1.6 μg/mL within a period of 72 h was 2.2%, indicating good stability and long service life of the sensor. The sensor was tested against spiked samples containing IBD, and recoveries between 89.7% and 97.4% were obtained with an RSD of 6.1%–8.6%. The performance of the sensor indicated its utility for practical sample analysis.

Varied metallophthalocyanine intercalated layered double hydroxides (LDHs) as bifunctional hybrid catalysts for selective epoxidation have been prepared and characterized. Systematic characterizations suggested the successful intercalation of the metallophthalocyanines into the interlayer of ZnAl LDHs. The synthesized hybrid exhibited excellent catalytic activity in the selective epoxidation of various olefins through O 2 /isobutaldehyde system. The basicity of the hybrid benefits to the selectivity of epoxide, and the bifunctional roles of the catalyst in the reaction have been discussed and verified by a series of controlled experiments. On the basis of obtained results, a probable mechanism of the epoxidation by the hybrid has been proposed and detailedly investigated. Under the catalysis of metallophthalocyanines intercalated LDHs in the presence of O 2 /isobutaldehyde, the production of epoxide undergoes two reaction paths. And two types of intermediates, namely acylperoxy radical and peroxyacid, are formed in the reaction, and the former is predominant.

Pantothenic acid (also known as pantothenate or vitamin B5), the obligate precursor of coenzyme A, is universally required in all branches of life. Although its biosynthetic pathways are well characterized, its catabolism remains poorly understood, constraining our insights into its broader biological roles and disease associations. By synergistic analysis of sequence similarity network (SSN) and genome neighborhood network (GNN) of pantothenate permease (UniProt ID: P16256 ) homologues, we identify a compact catabolic gene cluster for pantothenic acid in Geobacillus thermodenitrificans NG80-2. In vitro enzymatic activity assays indicate that pantothenic acid is first hydrolyzed to β-alanine and ( R )-pantoate by pantothenase belonging to the peptidase_M20-M20_dimer family (PF01546-PF07687), structurally distinct from the canonical pantothenase in amidase family (PF01425), and then ( R )-pantoate is sequentially oxidized into aldopantoate, ( R )-3,3-dimethylmalate, and α-ketoisovalerate by three dedicated dehydrogenases. The gene cluster is widespread within Bacillota phylum inhabiting high-temperature, hypersaline or alkaline niches, contrasting with previously described pathway restricted to Pseudomonadota, whose catabolic genes are scattered across the genomes. This work expands our knowledge about the pantothenic acid catabolism and reinforces the value of the transporter-focused genome mining strategy applicable for pathway discovery.

Soy sauce contains abundant flavor compounds, which are prone to change during storage. This leads to a decline in amino acid nitrogen content, accompanied by undesirable flavor shifts, including increased sourness and bitterness, as well as aroma deterioration. Using three metabolomics approaches, the compounds of 12 kinds of soy sauce were analyzed before and after accelerated shelf life testing (ASLT), identifying a total of 132 volatiles and 44 non-volatiles. Multivariate data analysis (OAV, TAV, OPLS-DA, FC and significance difference) pinpointed 9 key aroma and 15 key taste compounds in the shelf life of soy sauce, which were further verified by constructing a metabolite model and conducting sensory validation experiments. The sensory changes observed in soy sauce shelf life was explained at the metabolite level. This study conducted a comprehensive analysis of soy sauce quality changes during storage, which will be of significant theoretical value for the soy sauce industry development.

This study addresses the urgent demand for simple and sensitive online gas monitoring technologies in the field of environmental safety by developing a high-performance cataluminescence (CTL) sensor based on oxygen-vacancy-rich microporous titanium dioxide (Ovm-TiO 2 ) for detecting trace isobutyraldehyde (IBL). The Ovm-TiO 2 material, synthesized via a two-step heating process combined with a KBH 4 treatment, features abundant oxygen vacancy defects on its surface, which are pivotal to enhancing sensor performance. Density functional theory (DFT) calculations unravel the surface-mediated mechanism, the oxygen vacancies serve as active sites, drastically enhancing the chemical adsorption and activation of O 2 on the Ovm-TiO 2 surface, which is the key to boosting the cataluminescence efficiency. The developed sensor exhibits outstanding detection performance for IBL, with a wide linear range (0.0100–5.00 mg/L, R 2 = 0.9997), a low detection limit (3 μg/L), and achieved recovery rates of 87.6%–107% with good reproducibility (relative standard deviation, RSD: 5.3%–9.0%) in practical sample analysis. This work not only provides a viable online monitoring solution for IBL but also elucidates the CTL enhancement mechanism at the atomic level, offering important theoretical foundations and practical insights for designing highly sensitive gas sensors.

A three-channel sensor array based on Au@Pt NPs was constructed. • Au@Pt NPs with dual-function characteristics was designed. • Discrimination of light aroma-type Baijiu (LAB) was achieved. • Different years, production processes, price gradients, and adulterated were analyzed. • This method highlighted simple to operate, rapid in detection. The development of light aroma-type Baijiu (LAB) industry proposes a growing need for developing rapid and accurate discrimination method for the quality control of LAB. This study innovatively constructed a dual-mode three-channel sensor array based on the gold/platinum nanoparticles (Au@Pt NPs) with surface engineering. In this case, two colorimetric sensor channels based on ascorbic acid/para-aminophenol-chloroauric acid-nanozyme (AA/ pAP-HAuCl₄-Au@Pt NPs) and one fluorescent sensor channel based on nanozyme‑hydrogen peroxide- o -phenylenediamine (Au@Pt NPs-H₂O₂-OPD) were established. Experimental results demonstrate the colorimetric and fluorescence mode can accurately quantify four organic acids and three aldehydes in Baijiu, respectively. Samples including 17 different years and 9 different production processes of basic liquors of LAB, 48 different price gradients of commercial LAB, and adulterated LAB were analyzed. Discrimination with an accuracy exceeding 96% by Linear Discriminant Analysis, Hierarchical Cluster Analysis, and leave-one-out cross-validation was achieved. The dual-mode three-channel sensor array is characterized by simplicity, rapidity and accuracy, providing a new idea for the quality discrimination and market regulation of Baijiu.

In this study, the flavor quality of male and female mussel meat was investigated by sensory evaluation, gas chromatography-ion mobility spectrometry (GC‒IMS), gas chromatography‒mass spectrometry (GC‒MS) and metabolomics. The sensory evaluation results indicated that the flavor quality of male and female mussel meat was optimal when it was steamed for 8 min and that “fresh” was the most prominent odour attribute. The GC‒IMS and GC‒MS results revealed that aldehydes, ketones and alcohols were the characteristic flavor compounds in male and female mussel meat during different steaming times. Glycerol phospholipid metabolism was the main metabolic enrichment pathway shared by male and female mussel meat, and glycine (Gly), serine (Ser), and threonine (Thr) metabolism were the main metabolic pathways of female mussel meat. Phosphatidylethanolamine, phosphatidylcholine, phosphatidyl-L-serine, phosphatidylglycerol, and 1-acyl-n-glycerin-3-phosphocholine are the precursors of key odour compounds in male and female mussel meat at different steaming times.

Salicylaldehyde is a significant fine chemical product utilized in the flavoring of various foods, excessive intake of salicylaldehyde is detrimental to human health. Its accurate quantitative detection holds considerable importance. Compared with “turn-off” probes, the “turn-on”one allow for more sensitive detection. New silicon nanoparticles (D-SiNPs) which can be used to detect salicylaldehyde by “turn-on” mode were prepared in this work. This D-SiNPs demonstrates highly stability, selectivity and sensitivity. Within the concentration range of 5–50 μM, salicylaldehyde concentration exhibits a strong linear relationship with fluorescence intensity, the limit of detection is calculated to be 0.97 μM. It can be applied to detect salicylaldehyde in baked goods and beverages, achieving good recoveries. These results are highly satisfactory. The detect mechanism was investigated systemetically, the results illustrates this detection is based on Schiff reaction between the amino groups of silicon nanoparticles and aldehyde group of salicylaldehyde, which satisfies the ESIPT mechanism.
