In recent years, with the development of electric vehicles and electric vessels, the issues of battery thermal safety have garnered significant attention. Composite phase-change materials (CPCMs) hold great potential as passive cooling systems in battery thermal management systems (BTMS), but their high flammability remains an unresolved challenge. This study successfully developed a flexible composite phase-change material, CPCM/P-CSF@rGO, by encapsulating a eutectic phase-change material composed of mannitol and galactitol in a three-dimensional hydrogen-bonded network, self-polymerised by phosphated corn straw cellulose (P-CSF) and reduced graphene oxide (rGO). The study demonstrates that the strong hydrogen bonding network formed between the phosphate groups introduced by phosphoric acid modification and rGO constructs highly efficient thermal conduction pathways, achieving a thermal conductivity of 1.039 W/(m•K) and significantly accelerating thermal response rates. Simultaneously, the incorporation of the P-CSF@rGO framework endows the material with excellent flexibility and shape stability. Due to the in-situ flame-retardant modification of the framework, the phase-change material maintains a high latent heat of phase-change (194.7 J/g) and achieves superior flame retardancy through gas-phase and condensation-phase mechanisms. It exhibits a limiting oxygen index of up to 30.64% and rapidly extinguishes itself when exposed to open flame in atmospheric conditions. Thus, the flexible composite phase-change material (CPCM/P-CSF@rGO) supported by a phosphorylated cellulose framework emerges as a promising candidate for ensuring safety and high performance in thermal management applications.

Engineering inorganic matrices with optimized photon absorption and interfacial energy transfer is pivotal for advancing laser desorption/ionization mass spectrometry (LDI-MS) toward high-fidelity metabolomic analysis. Here, we developed a metal-organic framework (MOF)-derived porous iron oxide (pFO) nanomatrix for LDI-MS-based metabolomics. The pFO exhibits strong UV absorption at 355 nm, a high specific surface area (59.7 m 2 /g), and a uniform mesoporous structure, which collectively afford low background noise, enhanced analyte signal intensity, and high analytical reproducibility (coefficient of variation < 9.2%). Using this platform, metabolic fingerprints were rapidly acquired from 269 tobacco leaf samples. Integrated with Random Forest, the approach achieved accurate discrimination of leaf stalk position (AUC = 0.962) and reliable differentiation between southwestern and southeastern production regions (AUC > 0.944). Furthermore, eight representative m / z features were identified to construct a reduced classification panel, which maintained robust predictive performance in the test set (AUC > 0.913). This study establishes MOF-derived pFO as a high-performance inorganic matrix for LDI-MS metabolomics and establishes a rapid and reproducible analytical strategy for digital classification and quality traceability of agricultural products.

Hyper-osmotic stress in high-sugar fruits inhibits the fermentation performance of lactic acid bacteria (LAB). Besides, there is a prevailing trend of low-sugar diets for health concern. Therefore, it is essential to develop LAB strains with high-sugar tolerance and efficient sugar metabolism. In this study, three high-sugar-adaptive strains (2–12 mutations) were obtained through random mutagenesis and screening at 150 g/L glucose. When applied to high-sugar goji juice fermentation, they reduced glucose from 92.26 to 28.85 g/L, reached 2.56*10 9 CFU/mL, and shifted the sensory profile from sweet and herbal to fruity and pleasantly sour. Metabolomics revealed enrichment of bioactive metabolites such as indole-3-lactate (+22.32%), linoleate (+16.37%) and spermine (+64.50%) in strain LP-4-3*. Mechanistically, high-glucose-adaptive LAB accumulated more maltose, galactitol, and glycosylated phenolic compounds to alleviate osmotic pressure induced by high glucose. This study highlights the potential of high-glucose-adaptive LAB in developing low-sugar and health-promoting fermented fruit juices.

The structural characterization of polysaccharides requires precise determination of their monosaccharide composition, including the differentiation of D- and L-configurations. Current analytical methods can identify monosaccharide types but often fail to distinguish between enantiomeric configurations, posing a significant challenge for accurate polysaccharide structural elucidation. This study introduces a robust, accurate, and reproducible ultra-performance liquid chromatography-electrospray ionization-tandem mass spectrometry (UPLC-ESI-MS/MS) method to address this limitation. By utilizing ( S )-(−)-1-phenylethylamine (S-PEA) as a chiral derivatizing reagent, monosaccharide enantiomers are converted into diastereomers through the introduction of a new chiral center. This approach enables the simultaneous determination of D/L configurations for aldoses, amino sugars, alditols, and uronic acids, achieving excellent chromatographic baseline separation. Method validation demonstrated excellent linearity (R 2 > 0.9900) within the range of 2.5–160 μg/mL. The limits of detection (LOD) and quantification (LOQ) ranged from 0.04 to 0.11 μg/mL and 0.13–0.35 μg/mL, respectively, indicating high sensitivity. Accuracy was confirmed with recovery rates between 97.23% and 100.67%, while intra- and inter-day precision RSDs were below 3.54%. The method was successfully applied to characterize the monosaccharide composition of six plant-derived polysaccharides, demonstrating its efficacy in identifying both structural types and absolute configurations. These findings establish the proposed method as a valuable tool for advancing the comprehensive structural analysis of polysaccharides.

Sugar alcohols have been proposed as a class of potential phase change materials (PCMs) for medium-temperature latent heat storage . The present work investigated the cycling stability of four pure and three mixture sugar alcohols by a specially-designed test setup, followed by a comprehensive evaluation based on their phase change behaviors (reported in our previous publication) and stability. It was found that the latent heats of fusion/crystallization degrade upon consecutive melting-crystallization cycles, and a higher degree of superheat Δ T sh leads to a faster degradation. An extremely low level of only 10.5 % degradation was obtained for erythritol after 200 cycles at a relatively low Δ T sh of 20 °C. The corresponding degrees of supercooling Δ T sc become higher due to the remarkable reduction of crystallization temperatures . It was shown that introducing protective nitrogen gas could suppress oxidation and improve cycling stability. The cycles of half degradation on latent heat of fusion was ~3.6 times with nitrogen protection. A comprehensive evaluation identified that the crystallization-related issues and poor stability are the primary challenges for sugar alcohols. Nevertheless, other than common PCMs, some particular application scenarios like controllable latent heat retrieval and seasonal heat storage can be hopefully developed by virtue of the deep supercooling nature of sugar alcohols.

Composite phase change materials with sugar alcohol as the phase change material and highly thermally conductive ceramics as the porous skeleton are widely used in various thermal storage systems. The interfacial thermal conductance (ITC) between the phase change materials under different phases and the skeleton is an important factor affecting the rate of heat storage (release) in thermal storage systems. The ITC between ceramics(AlN, SiC) and sugar alcohols (mannitol and galactitol) in the solid and liquid states is investigated by means of both time-domain thermoreflectance and molecular dynamics simulations. The results show that the ITC between phase change materials and ceramic is better in liquid state than in solid state, and that the ITC between mannitol and ceramic is better, and that the ITC betweenAlN and sugar alcohol is better. More low-frequency phonons are involved in the thermal transport of the sugar alcohols in the liquid state, with an average overlap energy of about 9.5% higher than that of the solid state and an average phonon participation rate of about 6.8% higher. It was also found that it isthe H atom in the sugar alcohol that is linked to the C atom that governs the ITC.

The temperature-dependent rheological behaviors of five selected binary eutectic mixture sugar alcohols, with great potential for latent heat storage in the range of 353.15 K to 523.15 K, were investigated. It was found that the rheological behaviors of the mixture sugar alcohols depend on those of the pure compounds as well as their molar ratios. The two mixtures of xylitol (75 mol%)+erythritol and erythritol (84 mol%)+d-mannitol behave like pseudoplastic fluids with typical non-Newtonian shear-thinning behaviors, as indicated by the power law index of 0.99 (<1). The mixture of d-mannitol (70 mol%)+d-dulcitol is a nonlinear Bingham fluid, exhibiting a slight yield stress (0.001 Pa to 0.01 Pa) at low shear rates. The rest two mixtures containing the cyclic-structured inositol behave like Herschel-Bulkley fluids. The infinite shear viscosities of the eutectic mixtures over the entire temperature range appear to be higher than those of their respective pure compounds, except for inositol. The mixture of xylitol (75 mol%)+erythritol at its melting point shows higher dynamic viscosity of about 0.546 Pa·s than the values of about 0.396 Pa·s and 0.035 Pa·s for xylitol and erythritol, respectively. In addition, the activation energies of viscous flow of the mixtures, as determined by fitting the dynamic viscosity-temperature curves using the Arrhenius model, also exhibit higher values than those of their pure compounds. The activation energy of viscous flow of the mixture xylitol (75 mol%)+erythritol was determined to be about 92 400 J/mol in the supercooled liquid state, while the supercooled liquid xylitol and erythritol have much lower values of 83 500 J/mol and 51 900 J/mol, respectively. Both the increased dynamic viscosities and activation energies of viscous flow can result in deteriorated crystallization performance during latent heat retrieval.

The eutectic mixture of galactitol and mannitol with the melting point of 157.6 °C and high latent heat of fusion ( ΔH m =271.07 kJ/kg) is regarded as an ideal phase change material used in medium temperatures. However, the shortcomings of low thermal conductivity and severe supercooling restrict its application for thermal energy storage. To address these challenges, expanded graphite (EG) was introduced to obtain eutectic mixture/EG composites by vacuum impregnation method. SEM images showed that the pores of EG were filled by sugar alcohols and no chemical reaction happened during this process as confirmed by FTIR spectroscopy and XRD. The thermophysical properties of phase change material (PCM) composites were measured. The result revealed that the supercooling degree ( T sc ) of PCM composites decreased more than 26.2% compared to that of the eutectic mixture. Although the ΔH m of PCM composites decreased with an increase in content of EG, most of them are higher than 200 kJ/kg. Unlikely the ΔH m of PCM composites, the latent heat of crystallization ( ΔH c ) first rose by 15.3% and then dropped slightly. Their thermal conductivities were greatly improved by EG, especially with a 14 wt.% EG loading producing a more than 30-fold increase. Also, the PCM composite with 14 wt.% EG loading shows great form stability and thermal reliability after 20 charging-discharging cycles. These results prove that galactitol/mannitol eutectic mixture/EG composite has a promising prospect in potential for thermal energy harvesting and thermal management systems application.

Towards latent heat storage in the low-to-medium temperature range (70–250 °C), screening of sugar alcohols and their binary eutectic mixtures as potential phase change materials was carried out by focusing on the non-isothermal melting and crystallization behaviors. A preliminary screening shortened the long list of isomers from common four-carbon to six-carbon sugar alcohols to only six affordable candidates, i.e., xylitol, d-sorbitol, erythritol, d-mannitol, d-dulcitol and inositol (ordered with increasing the melting point). Based on the six pre-screened sugar alcohols, a total of 15 binary eutectic mixtures were prepared to manipulate the melting points for more flexible match with real applications. Non-isothermal tests were then performed on a differential scanning calorimeter at various ramping/cooling rates up to 10 °C/min. In addition to determination of the melting point and latent heat of fusion, a special attention was paid to the crystallization behaviors by undertaking consecutive melting-crystallization cyclic tests. It was found that the two candidates with the lowest melting points (both below 100 °C), i.e., xylitol and d-sorbitol, as well as the nine binary eutectic mixtures containing at least one of them, are unable to crystallize from the melt during cool-down at any cooling rates tested (down to 0.5 °C/min). Four other binary eutectic mixtures, i.e., erythritol (84 mol%) + d-mannitol, erythritol (95 mol%) + d-dulcitol, erythritol (96 mol%) + inositol and d-dulcitol (69 mol%) + inositol, were also shown to be unable to crystallize upon cooling, with the crystallization occurring during the reheating process instead, referred to as cold crystallization. The rest four pure sugar alcohols with relatively high melting points (110–230 °C), i.e., erythritol, d-mannitol, d-dulcitol, inositol, and two mixtures, i.e., d-mannitol (70 mol%) + d-dulcitol and d-mannitol (82 mol%) +inositol, were found to be able to crystallize upon cooling, although they all suffer from severe supercooling (e.g., up to over 100 °C for erythritol). The affordable pure and mixture sugar alcohols were deemed to have desirably high latent heat storage density, especially for those with higher melting points. However, they all face specific issues associated with crystallization, which must be addressed before they can really be utilized in real applications. In addition, it may not worth making eutectic mixtures, although this is deemed to be an effective way of manipulating the melting points of sugar alcohols.

The 2D BiOCl nanosheets with excellent photocatalytic activity were synthesized via the facile hydrothermal method by regulating the pH value of the precursor solution and using dulcitol (C 6 H 14 O 6 ) as the surfactant. The photocatalysts were characterized by XRD, FT-IR, SEM, TEM, BET, XPS, ESR, O 2 -TPD, EIS, DRS and PL. The results of morphological and structural characterization indicate that the pH has a large effect on the thickness of the nanosheets and the exposure ratio of {0 0 1} facets. The photocatalytic property of the sample prepared at pH 4 showed excellent visible-light photocatalytic performance to degrade RhB owing to the small thickness, the exposed {0 0 1} facets and the optimum concentration of oxygen vacancy. Moreover, the reasonable photocatalytic mechanism was revealed by the active species trapping experiments and ESR characterization, which suggested O 2 − and h + are the main active species in the present system.

Vanadium redox flow batteries (VRFBs) are considered a highly promising large-scale energy storage technology due to their long lifespan, high safety, large capacity, and high efficiency. In practical applications, pentavalent vanadium in the positive electrolyte of vanadium batteries is prone to precipitation under conditions of high temperatures and concentrations, reducing the energy density and cycle life of VRFBs. Therefore, choosing appropriate additives to improve the stability of pentavalent vanadium ions is crucial. This study researched the effects of two hexahydric alcohols (inositol and galactitol) as electrolyte additives on the performance of vanadium-positive electrolyte through X-ray diffraction (XRD), Raman spectroscopy, cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and charge–discharge tests. The results show that both inositol and galactitol can improve the electrochemical performance of vanadium-positive electrolyte. At a current density of 80 mA cm −2 , the energy efficiency of the battery groups with inositol and galactitol added increased by 1.24% and 3.28% respectively compared to the blank battery group. The capacity retention rates of the battery groups with inositol and galactitol added were both higher than that of the blank battery group after 50 cycles. Due to the different distribution spaces of hydroxyl groups, galactitol was more significant in enhancing electrochemical activity and increasing the stability of the electrolyte.

The identification of natural compounds with therapeutic efficacy for acute lung injury has consistently represented a critical area of research. Dulcitol, a natural product isolated from plants, is extensively used in the food and medical industries as a sweetener. Herein, we investigated whether dulcitol exerts an anti-inflammatory effect on LPS-induced acute lung injury (ALI) in mice. In our study, ICR mice were pretreated with dulcitol at dose of 6, 12 and 24 mg/kg for seven consecutive days, followed by intratracheally instilled with LPS (10 mg/kg) to induce acute lung injury. In vitro, RAW264.7 and A549 cells were incubated with LPS in the presence of dulcitol to investigate the anti-inflammatory activity and mechanism. The results demonstrated that dulcitol effectively inhibited the infiltration of inflammatory cells and reduced the excessive production of pro-inflammatory cytokines triggered by LPS to ameliorates acute lung injury in mice. Additionally, in vitro experiments indicated that dulcitol suppressed the release of NO, IL-6 and TNF-α while reducing mRNA expression levels of IL-1β, IL-6, COX-2, iNOS and TNF-α in RAW264.7 and A549 cells in a dose-dependent manner. Furthermore, dulcitol significantly decreased TLR4, MyD88, and TRIF levels and inhibited the translocation of NF-κB from the cytoplasm to the nucleus. Our finding suggested that dulcitol could serve as a protective agent against LPS-induced acute lung injury by inhibiting the TLR-4/NF-κB signaling pathway.
