The retrogradation of starch significantly impacts the quality of starch-based foods, making its inhibition critically important. This study employs an improved extrusion cooking technology to construct a composite system of corn starch (CS), palmitic acid (PA), and maltitol (MA), aiming to investigate the mechanism by which extrusion treatment (ET) synergizes with the addition of exogenous substances to inhibit starch retrogradation. The results showed that ET synergised with PA and MA significantly reduced setback Viscosity, breakdown Viscosity, iodine binding capacity, and average particle size of CS. After 7 d of storage, the retrogradation enthalpy, hardness and crystallinity of E-0.5 %PA-5 %MA were reduced by 68.75 %, 72.87 % and 59.97 % compared to CS. The Avrami equation indicated that the nucleation mode of all modified starches was transient. E-0.5 %PA-5 %MA inhibited the rate of starch recrystallisation better. In addition, its short-range ordered structure and helical structure also showed a decreasing trend, PA may formed a V-shaped structure with starch, and ET synergised with PA and MA hindered the rearrangement of starch chains during retrogradation and inhibited the retrogradation properties of CS. The results of this study provide new ideas for the design and development of starch-based food products and quality enhancement.

Titanium dioxide (TiO 2 ) has a strong oxidation effect when absorbing ultraviolet light. Therefore, when TiO 2 is used as a light stabilizer in polyvinyl chloride (PVC), it will cause the photodegradation of PVC. Herein, carbon quantum dots (CQDs) coated TiO 2 composite (TiO 2 @CQDs) was prepared by a one-step hydrothermal method. The prepared TiO 2 @CQDs were characterized by transmission electron microscopy (TEM), UV–Vis spectroscopy, X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy (FTIR), and X-ray diffraction (XRD). The photostability of PVC film containing TiO 2 @CQDs was investigated via photodegradation conductivity test, weight loss rate test, and ultraviolet aging test. Due to the down-conversion effect of CQDs under ultraviolet light, its existence can alleviate the photoaging of PVC. In addition, the thermal stability of PVC containing TiO 2 @CQDs was studied by conductivity tests and oven thermal aging tests. The presence of CQDs significantly improved the thermal stability of PVC. Meanwhile, the HCl absorption capacity of CQDs could reach 30.8 mg/g cat . According to the DFT calculations, this high absorption capacity is attributed to the HCl immobilization effect via forming hydrogen bonds between HCl and the keto oxygen, carboxyl keto oxygen in CQDs. The hydroxyl group in CQDs could also combine ZnCl 2 by forming a coordination bond.

A novel preparation scheme of thioglycerol-modified silica through thiol-epoxy click reaction was proposed aiming at introducing additional quantities of hydroxyl groups into the structure. When applied as the stationary phase of hydrophilic interaction liquid chromatography (HILIC) for separation of oligosaccharide compounds, the material revealed higher polar separation capability than which synthesized through traditional thiol-ene click reaction. Hydrogen-bond interactions were speculated to be the predominant retention mechanism, while partitioning also participated in the retention of disaccharides and trisaccharides. The column also showed good stability and inter-batch reproducibility. Finally, the column was employed for determination of oligosaccharide compounds in commercial beverages, and good linearities, high accuracy, favorable precision, satisfactory reproducibility and resistance to matrix interference were achieved. In the detection of real samples, the determined content was consistent with the labeled content. This work provided an efficient and practicable method for quantity monitoring of commercial diet drinks in routine laboratory.

Carbon quantum dots (CQDs) can be used to modify TiO 2 to extend the light absorption threshold and enhance its photocatalytic efficiency. In this study, different amounts of CQDs modified TiO 2 (CQDs-x/TiO 2 ) were synthesized by a facile, mild, and environmental friendly hydrothermal method at a low temperature. The physicochemical properties were investigated by a variety of advanced characterization techniques. It was found that the anchoring of CQDs endowed the CQDs-x/TiO 2 with a large specific surface area, which is beneficial to adsorb more organic pollutants and promote the rate of photocatalytic oxidation. The XRD results also showed that the in situ formation of CQDs on the surface of TiO 2 made the crystallinity of TiO 2 tend to be complete. Among these photocatalysts, CQDs-20/TiO 2 showed the highest pollutant removal efficiency under visible light irradiations. The classical quenching tests revealed that the O 2 •− , • OH, and hole (h + ) were the oxidizing species. Among them, h + was the primary factor contributing to the degradation. The electrochemical tests showed that the anchoring of CQDs on TiO 2 increased the photocurrent by about four times, as compared with the pure TiO 2 . In particular, the cyclic voltammetry results showed that the photo-generated electrons of CQDs were freer to transfer to TiO 2 under visible light irradiations, promoting the separation of photo-generated electrons and holes. This study explains adequately why the CQDs/TiO 2 system has a good photocatalytic degradation of organic compounds.

Producing heat-stable, bloom-resistant chocolate is a significant challenge faced by the food industry. This study prepared oleogels using palm oil as a base oil and monoglyceride stearate as an oleogelator, which were introduced into partially substituted cocoa butter (CB) (30% w/w) to manufacture heat-stable, bloom-resistant chocolate. In addition, various healthy sweeteners (maltitol (M), tagatose (T), and palm sap sugar (PS)) were used (corresponding chocolate noted as Choc M100, Choc T5 & T10, and Choc PS25 & PS50, respectively) at different substitution ratios to sucrose . The melting properties and fat blooming behavior were characterized to optimize the suitable recipe for the chocolate. According to the results, Choc PS50 exhibited the required crystal form (β-form), improved the shape retention index (SRI), displayed a higher melting enthalpy ( Δ H m ) and ideal fat bloom-resistance, while showing fewer superficial crystals during temperature cycling (16 h at 20 °C and 8 h at 32 °C for 40 d). Nevertheless, the formulated chocolates exhibited significantly lower hardness due to the reduced CB content. This study provided an approach to manufacturing heat-stable, bloom-resistant chocolate.

Simultaneous chromatographic separation of the anomers of saccharides was achieved by using a polymer zwitterionic stationary phase functionalized by acrylamide-type sulfobetaine. By optimization of separation parameters including column temperature, pH, and flow rate, the column operated in hydrophilic interaction chromatography mode exhibited excellent separation selectivity toward five monosaccharides and their anomers (including ribose, xylose, galactose, glucose, and arabinose) and two disaccharides (lactose and maltose). Baseline separation could be achieved at mild operation conditions such as 20–30°C of column temperature or typical mobile phase composition (85% acetrontrile–15% 20 mM ammonium formate [NH 4 FA]) with wide pH tolerance range of 2–8. This offers a rapid way to determine the configuration of α or β anomer of the saccharides.

Aqueous zinc-ion batteries (AZIBs) have triggered a surge of scientific research due to the unique merits of high safety, volumetric specific capacity, and environmental benignity. However, the implementation of this technology is still plagued by the lack of high-performance cathodes that can output high energy density and exceptional cycle life and inadequate Zn reversibility. Here, an organic-inorganic hybrid cathode based on a poly(3,4-ethylenedioxythiophene) (PEDOT) intercalated hydrated vanadium oxide (denoted PVO), which delivers an ultrahigh discharge capacity of 513.1 mAh g −1 (0.5 A g −1 ) and an ultra-stable cycle with 95.3 % capacity retention and approximately 100 % Coulombic efficiency over 2000 cycles (20 A g −1 ), is developed. Combining substantive measurements and theoretical calculations, it is demonstrated that favorable structural features with expanded interlayer galleries and robust architecture are believed to be responsible for the enhanced electrochemical performance, which can be further boosted by the improved Zn reversibility because of the introduction of maltitol electrolyte additive. This work provides a new attempt to achieve organic-inorganic composites for high-performance cathode materials of AZIBs and new insights into the charge storage behavior under the synergistic regulation of bilateral interfaces.

Increasing the migration and separation efficiencies of photogenerated carriers can enormously enhance photocatalytic properties. Thus, a novel CQDs/BiOCl nanocomposite with rich oxygen vacancies (OVs) was effectively synthesized via a hydrothermal method by using maltitol as a carbon source to address these issues. The photocatalysts were characterized by XRD, SEM, TEM, FT-IR, BET, XPS, PL, EIS, I-t, DRS and ESR. The experimental results demonstrate that BOC-1 can purify 72% tetracycline hydrochloride (10 mg/L, TC-HCl) within 60 min, which is 4 times higher than pure BiOCl. Moreover, photocatalytic mechanism was thoroughly studied and verified that the cooperation of point discharge effect (PDE) and rational OVs concentration induced by carbon quantum dots (CQDs) can significantly enhance the migration and separation of photo-induced carriers, thereby leading to high photocatalytic activity of the as-prepared nanocomposites. In addition, the contribution of the free radicals was comprehensively calculated based on trapping experiments. the contributions of ·OH, ·O 2 - and 1 O 2 are 6.38%, 48.94% and 8.51%, respectively. This study provides a promising strategy to boosting the photoinduced carrier transfer properties by the coupling of point discharge effect and defect engineering.

In the process of printing and copying, the volatilization of toner produces tiny particles and harmful gases that are detrimental to the human body. Low-temperature printing and copying can reduce harmful gas emissions. Styrene acrylic resin is the main component of toner and the thermal conductivity of toner can be improved by increasing the thermal conductivity of styrene acrylic resin. In this paper, hexagonal boron nitride (h-BN), carboxyl modified multi-walled carbon nanotubes (MWCNTs-COOH) and graphene hybrid fillers were added into styrene acrylic resin to improve the thermal conductivity of resin composite by forming a connected thermal conductivity network in resin. The experimental result shows that the thermal conductivity of the h-BN/styrene acrylic resin composite increases with the increase in h-BN filler content (0-20wt%). When 20.0 wt% h-BN is added into styrene acrylic resin, the thermal conductivity is increased by 83.63%. Hybrid fillers (MWCNTs-COOH/graphene and 3.0 wt% h-BN) were added in styrene acrylic resin and the thermal conductivity of the composite is almost the same or higher than that of 20.0 wt% h-BN/styrene acrylic resin composite. The thermal conductivity of styrene acrylic resin composites improved by 69.57% and 87.14% via adding 1.5wt% CNTs-3 wt% h-BN and 1.0wt% graphene-3 wt% h-BN. MWCNTs-COOH or graphene can bridge isolated h-BN aggregates to form a thermally conductive network in styrene acrylic resin, while the addition of graphene improves the thermal conductivity of resin composite higher than that of MWCNTs-COOH.

In this study, carbon quantum dots (CQDs) were synthesized by a low-cost and scalable approach and the oxygen functional groups were fine-tuned by chemical post-treatment. It was found that the CQDs could be applied as visible-light-responsive photocatalysts for activation of peroxymonosulfate (PMS) and remediation of aqueous organic dyes. Phenylhydrazine modified CQDs (CQDs-PH) presented high efficiency for degradation of methylene blue due to selective removal of carboxylic groups and inhibited recombination of photogenerated electron-hole pairs. The effects of catalyst dosage, species and concentrations of dyes, and initial pH values on the photodegradation efficiency were systematically investigated and the alkaline condition facilitates the separation of photoinduced charge carriers and promotes the dye decoloration. The reactive oxygen species produced in the photocatalysis were identified by radical quenching tests and the mechanism was elucidated. Superoxide radicals were generated from PMS activation via electron transfer from CQDs and played the primary role in organic oxidation. In addition, photogenerated holes on the valence band of CQDs also participated in the dye decomposition.

To achieve a promising application prospect in nanofiltration (NF) membrane separation , a strategic design tailored to particular functions is crucial. Here, tailor-made thin film nanofibrous composite (TFNC) NF membranes for specific applications were fabricated via interfacial polymerization (IP) between maltitol and trimesoyl chloride (TMC) on PAN nanofibrous substrates. Owing to the moderate reactivity of maltitol, a range of sugar alcohol based polyester membranes with different morphologies and cross-linking degrees were obtained by varying the monomer concentration as well as the reaction time. In this case, the finely tuned loose Mal1-TMC0.2-2 membrane exhibited a prominent permeability (110.34 L m −2 h −1 bar −1 ) and an extraordinary selectivity for dye/salt mixed solution, with the rejection of Congo Red up to 99.11 % and NaCl retention of only 7.41 %, indicating its suitability for textile wastewater treatment . Further, the dense Mal2-TMC0.4-10 membrane showed an excellent Na 2 SO 4 rejection of 97.40 % with a good permeability of 18.65 L m −2 h −1 bar −1 , making it a candidate for seawater and brackish water desalination . In addition, both membranes demonstrated reliable chlorine and pressure resistance along with long-term stability. This study provided new insights and inspiration to the design and preparation of NF membranes for specialized applications.

Oxidation resistance is strongly necessary for the use of crosslinked ultrahigh molecular weight polyethylene (UHMWPE) in artificial joints. The hybrid antioxidant strategy emerged as a promising alternative to the single rival that relies on vitamin E (VE). The goal of this study was to investigate the universality of the antioxidant synergy between VE and sugar alcohol (SA). Three types of SA, including D-sorbitol, maltitol and erythritol, were employed to cooperate with VE. Compared to the use of VE alone, these hybrid antioxidants generally enabled the corresponding UHMWPE composites with prolonged oxidation induction time (OIT) and increased crosslink density. The correlation between OIT and crosslink density of VE/SA-stabilized UHMWPE composites showed low attenuation. The applicability of the hybrid antioxidants to protect UHMWPE against oxidation was further demonstrated using the in vitro clinically relevant accelerated aging. Among the used SA, D-sorbitol exhibited the strongest ability to enhance the synergetic efficiency. The possible mechanism was revealed from the following aspects: the number of secondary hydroxyls per molecular mass and the molecular polarity determined via polarity parameter calculation. These findings provide significant insights for fabricating UHMWPE bearing materials with superior comprehensive performance and extended service longevity.
