Summary: This study combined laser direct in-frared (LDIR) and Fourier-transform infrared (FTIR) methods to investigate microplastics in agricultural soils. The results showed that microplastics were present in high abundance, with particles ranging from 10 to 500μm accounting for the majority. Polyethylene, polypropylene, and polyvinyl chloride were the dominant polymer types. Reclaimed water from sewage treatment plants, drip irrigation utilities, and residual plastic film were identified as potential sources. The study also highlighted the underestimation of microplastic contamination in agricultural soils using visual counting methods.

Summary: A spectral analysis tool called SpecQuant has been developed to identify and quantify gas-phase species from complex infrared spectra. It can handle both reference and experimental data with varying resolution and instrumental lineshape. The software uses classical least squares model and reference spectra to determine the mixing ratio of each species along with its estimation error. SpecQuant also provides visual inspection of the fit and residuals by displaying the calculated mixing ratio versus experimental data for each analyte.

Summary: Infrared devices are increasingly used in various applications. This paper introduces a novel dispersive spectrometer that has high-throughput and decoupled spectral resolution. The proposed spectrometer utilizes a two-stage Hadamard transform encoding process to increase the signal-to-noise ratio. With a single-pixel detector, the system can be easily implemented in other desired wavelengths. Additionally, a method is developed to remove the need for uniform illumination and improve the ease of device design for in situ measurement.

Summary: This study revealed that a large amount of microplastics and nanoplastics are generated during the eyeglass lens polishing process, which cannot be effectively removed by conventional wastewater treatment processes and have strong adsorption capacity for environmentally hazardous chemicals. Quantitative analysis showed high levels of microplastics and nanoplastics in wastewater, potentially leading to significant exposure risks for workers in eyeglass shops.

Summary: The traditional manual analysis of microplastics has its drawbacks, such as being labor-intensive, inaccurate in identification, and lacking uniformity. Automated analysis strategies based on vibrational spectroscopy, including laser direct infrared, Raman, and focal plane array-Fourier transform infrared imaging, have been developed. Each strategy has its advantages and limitations in terms of quantification, detection limit, size measurement, and material identification accuracy and speed.

Summary: Diabetes is a chronic metabolic disorder characterized by an increase in glucose caused by autoimmune destruction of insulin-producing cells or tissue resistance to insulin. It can lead to cardiovascular and renal complications, as well as retinopathy, causing a significant decline in the patient's health. Fourier transform infrared spectroscopy has emerged as a non-invasive method to accurately detect diabetes, and chemometric methods can improve its accuracy. However, there is currently no unified assay for its detection, and more research is needed to establish a single protocol for clinical settings.

Summary: This study demonstrates a high-throughput approach using laser direct infrared (LDIR) spectroscopy to detect and characterize microplastics (MPs) in surface water samples. The method allows for quantification of MPs based on shape, size, and polymer type, and utilizes infrared analysis for polymer identification. The simplicity and automation of LDIR make it an attractive option for large-scale, high-throughput analysis of MPs.

Summary: Plastics are a common pollutant in the marine environment, and there is a lack of data on microplastics in the Atlantic Canada region. The study found that most of the plastics were microplastics, especially plastic fragments. Polyethylene and polypropylene were the main types of plastics. These findings have implications for future research and can inform environmental groups, government, and academia.

Summary: The validated diffuse reflectance infrared Fourier transform spectroscopic method for quantitative analysis of levofloxacin in solid dosage forms provides an eco-friendly approach with precise and accurate results. The linear calibration curve obtained in the study demonstrated high correlation coefficient and the method was found to be suitable for solid state samples. The proposed method showed good precision, accuracy and reproducibility, making it appropriate for quantitative analysis of levofloxacin in solid dosage forms.
