Summary: This study investigated the interaction between boric acid and a polyphenolic SOM analogue, tannic acid, at varying concentrations under different pH conditions. The results showed that boric acid enhanced the deprotonation of tannic acid at pH = 7 and 9, leading to an increasing binding affinity between boric acid and tannic acid from pH = 5 to 9.

Summary: This study validated a model for the classification of wood species and a universal model for the rapid determination of cellulose, hemicellulose, and lignin using FTIR spectroscopy coupled with chemometrics. The results showed that the full spectra can be used to differentiate different species and identify infrared peaks associated with cellulose, hemicellulose, and lignin. In addition, the full spectra helped build a three species universal model for quantifying the principal wood chemical components. Therefore, the study demonstrated that FTIR-ATR, together with chemometrics, is a reliable method for discriminating wood species and determining wood chemical composition.

Summary: Mid-infrared spectroscopy and chemometric techniques were used to verify the authenticity of commercial prato cheeses. Analysis of the samples showed that 16 commercial samples overlapped with mozzarella cheese and 4 overlapped with prato cheese. Discriminant methods yielded classification rates above 84%. These techniques efficiently differentiated and classified the samples, indicating that commercial samples were likely not authentic prato cheese.

Summary: The coronavirus pandemic poses a significant threat to human health, and early detection and prevention of further escalation are of utmost importance. The current method of sample collection and RNA testing using the nasopharyngeal swab method and real-time polymerase chain reaction has limitations. Optical techniques, such as optical sensing, spectroscopy, and imaging, show promise in virus detection due to their speed, accuracy, and cost-effectiveness. This mini review summarizes the development of vibrational spectroscopy techniques for the detection of the SARS-CoV family, highlighting their advantages and future possibilities in the field of photonics-based devices for COVID-19 detection.

Summary: This study examined the mutual effects of albumin and liposomal membrane in terms of quantity of bound protein, its structure, liposome membrane permeability, and changes in physicochemical characteristics of the liposomes. The results showed that a small amount of tightly bound protein had a detectable impact on the liposome, and the composition of the liposome bilayer and its microhydrophobicity were partially related to albumin conformational changes. Ganglioside GM(1) showed preferable features for evading undesirable structural changes.

Summary: The CO2/O2 fluxes ratio, known as the apparent respiration quotient (ARQ), provides valuable information about respiratory-substrate stoichiometry and non-respiratory processes. This study investigated the variability of ARQ in a Mediterranean oak forest over 15 months. The results showed that ARQ values varied in different tissues, with CO2 re-fixation affecting tree stems and wound-response O2 uptake affecting fresh tissues. The study also found that soil ARQ was lower than expected, indicating the stoichiometry of the organic matter sub-pool supporting respiration. The ARQ values in soil air and root air demonstrated the potential to distinguish autotrophic and heterotrophic sources of soil respiration. The limitations of this method were also discussed.

Summary: This study compared different laboratory aging methods to simulate biochar aging using a decade-scale natural charcoal aging event. The results showed that oxidation with 30% H2O2 most accurately simulated most properties of ten-year field aging. UVA aging and NH2Cl aging showed distinct differences compared to field aging. By reducing the number of measured physicochemical properties, biochar aging can be accurately predicted.

Summary: In this study, the influence of transition metal doping on the electronic and mechanical properties and electrochemical performance of 2HMoS2/NC was investigated using Cobalt (Co) as an example. Co doping was found to effectively improve the electronic conductivity and active site areas of 2H-MoS2/NC at different positions, optimizing the adsorption and diffusion capability of potassium ions. Furthermore, the study revealed the optimal roles of different types of nitrogen atoms in kinetic adsorption, diffusion, and interfacial stability of potassium ions. These findings provide guidance for the experimental design of high rate 2H-MoS2/NC electrode materials and the optimal design of other functional composite materials.

Summary: This research developed an effective approach to enhance the charging rates of lithium ion batteries (LIBs) by strategically incorporating carbon nanotube (CNT) conductivity boosters into Li4Ti5O12 (LTO) electrodes. Multi-layer architectures comprising CNT-rich and CNT-free LTO electrode layers were manufactured using a layer-by-layer spray coating method to promote charge transfer kinetics of high mass loading electrodes. The best performing multi-layer was paired with a spray-coated LiFePO4 (LFP) positive electrode, resulting in attractive power performance that outperformed conventional LTO || LFP combinations.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
