“…Additional experiments are needed to explore the full range of different parameters and interactions in order to find the conditions for the highest system output. This is in line with approaches followed in several other recent studies, where the output has been optimized considering all the experimental variables and interactions involved therein. − In the case of the present study, similar optimization may be performed in the future, considering the uncertainties in the properties of the catalysts, variability associated with the dimension of the experimental chamber, and the reaction conditionsmuch like the chemometric approaches followed in studies related to biosensing, energy, and food science and technology …”

Ultrasensitive detection of enzyme inhibitors and heavy metal contaminants in effluents constitutes a major interdisciplinary research area. Multiple methods based on colorimetry, conductance measurement, reactivity estimation, etc., have been developed in this direction, which often involve the use of sophisticated equipment and complex methodologies. Herein, we present a simple, table-top technique for the detection of enzyme inhibitors and industrial effluents using convective flow-assisted propulsion of catalytic palladium nanoparticle (NP)-coated polymer motors in solution. The motors display buoyancy-driven self-propulsion, which is further enhanced in the presence of secondary catalysts like catalase and horseradish peroxidase, generating auxiliary convection in the experimental chamber. The convection and the motor propulsion were sensitive toward molecules that inhibited the enzyme activity, thereby offering a platform for using NP-coated catalytic motors as dynamic sensing probes for harmful chemicals in liquids. Initially, effective sensing of trace amounts of Cu 2+ , Ag + , and Cd 2+ ions was performed based on the reduced propulsion of the catalytic motors through the fuel solution. The detection limit of Cu 2+ in the aqueous environment was found to be less than the permissible limit suggested by the Central Ground Water Board (CGWB), Government of India. Experiments were also conducted to demonstrate the generic applicability of motor-based detection of different enzyme inhibitors (in the micromolar concentration range), such as a flavonoid (hydroquinone) and an aromatic dipeptide (diphenylamine). Finally, it was demonstrated that the catalytic NP-coated polymer motors could also be used effectively to detect industrial effluents using samples containing different compounds that acted as enzyme inhibitors. A simple model connecting the enzyme inhibition and motor propulsion speed is presented to explain the experimental observations.

“…In previous works, − the ROIMCR method has been applied for gas chromatography (GC)- and LC-HRMS analysis using full-scan MS1 detection only, especially in metabolomics and proteomics studies , and more recently for environmental studies. , The advantage of using this approach compared to other in the literature like MS-DIAL, CorrDec, XCMS, or metaboanalyst is precisely that it is based on the concept associated with the bilinear factor decomposition and resolution of the components of a mixture (component resolution) instead of on the concept of individual peak feature selection and deconvolution. In this work, special attention is paid to the bilinear factor decomposition of both MS1 and MS2 data simultaneously (data fusion).…”

New data-independent acquisition (DIA) modes coupled to chromatographic separations are opening new perspectives in the processing of massive mass spectrometric (MS) data using chemometric methods. In this work, the application of the regions of interest multivariate curve resolution (ROIMCR) method is shown for the simultaneous analysis of MS1 and MS2 DIA raw data obtained by liquid chromatography coupled to quadrupole-timeof-flight MS analysis. The ROIMCR method proposed in this work relies on the intrinsic bilinear structure of the MS1 and MS2 experimental data which allows us for the fast direct resolution of the elution and spectral profiles of all sample constituents giving measurable MS signals, without needing any further data pretreatment such as peak matching, alignment, or modeling. Compound annotation and identification can be achieved directly by the comparison of the ROIMCR-resolved MS1 and MS2 spectra with those from standards or from mass spectral libraries. ROIMCR elution profiles of the resolved components can be used to build calibration curves for the prediction of their concentrations in complex unknown samples. The application of the proposed procedure is shown for the analysis of mixtures of per-and polyfluoroalkyl substances in standard mixtures, spiked hen eggs, and gull egg samples, where these compounds tend to accumulate.

“…Polymers have helped satisfy human needs and are gaining significant importance on a daily basis due to their multiple applications [ 1 , 2 , 3 , 4 , 5 ]. Polymers are widely used in manufacturing automotive parts, household appliances, electrical instruments, food containers, homes, medical products, water purification and many other applications [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 ]. Their many applications are clearly in great demand, based on the fact that the annual production of polymers ranges from 359 to 380 million tons per year.…”

“…Their many applications are clearly in great demand, based on the fact that the annual production of polymers ranges from 359 to 380 million tons per year. Of the production volumes, a significant percentage ends up in various bodies of water and it becomes one of the most critical environmental pollutants on the planet [ 3 , 4 , 5 , 9 , 10 , 11 ]. Currently, one of the most serious types of harm that are caused by plastic is the generation of bioaccumulative microplastics [ 12 , 13 , 14 , 15 ].…”

“…HPW is not a clean or pure plastic that can be quickly recovered or processed as it is impregnated with infectious biological residues, chemical traces, pharmaceutical residues, sensitive materials, and cytotoxic and radioactive substances [ 7 , 16 , 18 , 19 , 20 ]. This means that HPW is among the most significant contributors to global waste [ 3 , 19 ] since it is part of the waste that usually results from the routine activity of medical centers, clinics, hospitals, and any institution or organization related to health, specifically patient care [ 16 , 18 , 19 ]. Therefore, 10% and 25% contain chemical species classified as infectious, toxic, and polluting.…”

In this study, the thermal degradation and pyrolysis of hospital plastic waste consisting of polyethylene (PE), polystyrene (PS), and polypropylene (PP) were investigated using TG-GC/MS. The identified molecules with the functional groups of alkanes, alkenes, alkynes, alcohols, aromatics, phenols, CO and CO2 were found in the gas stream from pyrolysis and oxidation, and are chemical structures with derivatives of aromatic rings. They are mainly related to the degradation of PS hospital waste, and the alkanes and alkenes groups originate mainly from PP and PE-based medical waste. The pyrolysis of this hospital waste did not show the presence of derivatives of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans, which is an advantage over classical incineration methodologies. CO, CO2, phenol, acetic acid and benzoic acid concentrations were higher in the gases from the oxidative degradation than in those generated in the pyrolysis with helium. In this article, we propose different pathways of reaction mechanisms that allow us to explain the presence of molecules with other functional groups, such as alkanes, alkenes, carboxylic acids, alcohols, aromatics and permanent gases.
