Summary: This paper proposes a quantitative analysis method for Panax notoginseng using terahertz time-domain spectroscopy and two-dimensional correlation spectroscopy (2DCOS). By using temperature perturbation and 2DCOS, the differences in characteristic information between different P. notoginseng contents can be clearly reflected. A competitive adaptive reweighted sampling (CARS) method is used to extract the feature information of P. notoginseng contents from the 2DCOS synchronous spectra, and a quantitative model called 2DCOS-CARS-SVR is built using support vector regression machine (SVR). The analysis results are more accurate than the commonly used PCA-PLSR and PCA-SVR methods, with a prediction set correlation coefficient of 0.9915% and root mean square error of 0.8160%.

Summary: We demonstrate the usefulness of direct near-infrared (NIR) bile analysis for identifying gallbladder (GB) cancer. By employing two-trace two-dimensional (2T2D) correlation analysis, dissimilar spectral features among diverse bile samples were recognized, leading to potential improvement of discrimination accuracy. The altered metabolic pathways in GB cancer samples result in different NIR spectral features compared to other sample groups. The discrimination accuracy is enhanced to 95.6% when employing 2T2D correlation analysis and a reference spectrum constructed from five pure representative bile metabolites.

Summary: This paper presents methods for analysing the source and amplitude of temperature disturbance based on two-trace two-dimensional correlation spectroscopy (2T2D-COS) to improve the accuracy of quantitative analysis. The absorption spectra of glucose solution at different temperatures were analyzed using the 2T2D-COS algorithm. Distinct cross peaks corresponding to water and glucose were observed in the concentration-dependent and temperature-dependent spectra. The intensity of the peaks at 1 410 nm increased with temperature, indicating a good correlation between the cross peaks and temperature variance. A calibration model was established using the cross peak intensity, achieving a root mean square error of 0.125 9 degrees C for sample temperature prediction.

Summary: In recent years, near infrared (NIR) spectroscopy has been explored for its potential in bacteria strain identification. By correlating NIR and mid-infrared (mid-IR) spectra, researchers were able to establish a model with an 85% correct classification rate, which increased to 94% when selecting NIR wavelengths with high correlation to important mid-IR peaks. This correlation analysis revealed relationships in the NIR spectra of biological samples, contributing to a better understanding of these spectra.

Summary: Diffuse reflectance FTIR measurements with 2D-COS were used to accurately identify the bands of chernozem soil organic matter (SOM) and mineral silicate matrix. The study compared samples from different land use types of a long-term field experiment. Homospectral and synchronous 2D-COS maps revealed correlation regions related to hydrogen bonds, SOM, and quartz matrix. The SOM range had distinct signatures, distinguishing different land use pairs. Asynchronous 2D-COS maps showed bands related to the proportion of silicate to quartz in small fractions, as well as carbonyl, carboxylate, and aromatic C-C in larger factions. The proposed approach provides reliable identification of SOM components with weaker IR bands compared to the mineral matrix.

Summary: To improve the accuracy of adulterated milk discrimination, a detection method based on temperature-perturbed generalized two-dimensional (2D) correlation characteristic slice spectra was proposed. A total of 240 samples were prepared and the infrared attenuated total reflection spectra were collected at different temperatures. Discrimination models based on 2D correlation characteristics slice spectra were established using N-way partial least squares discriminant analysis (NPLS-DA). The results showed that the proposed method effectively extracted characteristic information and improved the accuracy of discrimination.

Summary: A novel method for NIR spectroscopy spectra standardization is proposed in this paper. Most existing methods for standardization require spectral data sets from both primary and secondary instruments for validation, which limits their usage. This paper investigates the issue of spectrum data order and develops a different approach based on statistical signal processing. The developed method compensates for distortion and transfers the second order statistic from the primal spectra to the secondary spectra, allowing estimation regardless of the sample statistic order. Application-driven experiments and a comparison to PDS are conducted to demonstrate the extended usage of the method in NIR spectra standardization.

Summary: Conductive textiles can be created by coating fabric with liquid metal particles, which provides possibilities for human-machine interfaces and wearable electronics. In this method, the fabric is dipped into a suspension of liquid metal particles at room temperature. The coated fabric remains electrically insulating due to the native oxide on the particles, but can become conductive by compressing it to rupture the oxide and allow particle percolation. Conductive circuits can be patterned on the textile by compressing it with a patterned mold. The electrical conductivity of these circuits can be improved by increasing the particle coating. The LM-coated textiles also possess antimicrobial protection against Pseudomonas aeruginosa and Staphylococcus aureus, and the conductive patterns autonomously heal when cut.

Summary: Metals, like gallium, can supercool even in the presence of nucleation sites. The native oxide on gallium provides a smooth interface that prevents direct contact with surfaces, promoting supercooling. Differential scanning calorimetry shows that gallium with oxide freezes at a lower temperature than without oxide. These findings have implications for applications that rely on gallium's liquid state.

Summary: In this study, hierarchical structures were fabricated on the surface of polyurethane acrylate (PUA) film, which exhibited antibacterial properties. The PUA film was created by coating PUA resin onto a commercial porous anodized aluminum oxide (AAO) template and using nanoimprint lithography. Zinc oxide structures were grown on the imprinted PUA sample through a hydrothermal method. The antibacterial behavior of the sample was tested against Staphylococcus aureus (S. aureus) and Pseudomonas aeruginosa (P. aeruginosa), showing moderate antibacterial properties against both strains and enhanced antibacterial activity against P. aeruginosa with the presence of ZnO structures.
