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: Applications of vibrational spectroscopy to assess bone disease and therapeutic interventions are continually advancing. Different bone compositions were observed among the control wildtype (WT) and OIM groups using NIR spectral analysis, with NIR parameters showing greater sensitivity to bone composition differences.

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: The study investigated the effects of accelerated ageing on the physio-mechanical, chemical, and biological properties of wood, as well as the properties of pulp paper produced from the treated wood materials. Accelerated ageing significantly impacted the mechanical and chemical properties of the studied wood species, leading to changes in pulp paper properties.

Summary: The study introduces a high-speed FTIR spectroscopy technique called phase-controlled Fourier-transform infrared spectroscopy (PC-FTIR) capable of measuring MIR absorption spectra at a rate of above 10 kHz. It demonstrates a high scan rate with a high signal-to-noise ratio for various spectral bandwidths by arbitrarily adjusting the instrumental spectral resolution. This high-speed MIR spectrometer could be particularly useful for measuring non-repetitive fast phenomena and acquiring a large amount of spectral data within a short time.

Summary: This study evaluated the potential of FTIR spectroscopy as a diagnostic tool for medulloblastoma (MB). The results showed significant differences in FTIR spectra between MB and normal brain tissue, indicating that FTIR spectroscopy can be used to differentiate them to some extent. Therefore, it may be a valuable method to expedite and enhance histological diagnosis.

Summary: Partial evaporation and solidification of plastic materials, mainly microplastics, onto coastal rocks can form a new solid structure called plastitar. These formations have been found in several islands of the Canary Islands archipelago and can permanently attach to the rock, occupying a significant portion of the sampled area. The plastitar primarily consists of tar and polyethylene, with microplastics in the form of fragments, pellets, and lines. The increasing presence of plastics, particularly microplastics, in coastal environments may lead to the common occurrence of these new plastic formations, which require further investigation on their long-term effects on coastlines.

Summary: Soil salinity has a significant impact on agricultural production, especially in low-lying coastal areas where saltwater intrusion is a growing concern. Monitoring salinity is challenging due to the influence of soil moisture on the soil's spectral signature. The study found that Fourier-transform infrared spectroscopy can be used to map salt-affected soils, particularly in inaccessible areas. Advancements in thermal satellite sensors may provide possibilities for monitoring soil salinity in the future.

Summary: This study confirmed the possibility of using FTIR spectra and multivariate analyses to accurately assign milk samples to their breeds of origin. R-VAL(2) values obtained with the CRV procedure were moderate to high for the majority of coagulation traits, with RMSEVAL and ratio performance deviation values increasing as the coagulation process progresses from rennet addition. Prediction accuracy obtained with the SCV were strongly influenced by the breed, presenting general low values restricting a practical application.
