The study investigates the gelation kinetics of gelatin in the presence of various saccharides, including common sugars (sucrose, fructose, & glucose), rare sugars (ribose, allulose, isomaltulose, & trehalose), and prebiotic trisaccharides (raffinose and 2′-fucosyllactose). Gelation kinetics, including the initial sol-gel transition and subsequent aging, was monitored using a rheometer, while gel properties were assessed through texture analysis, differential scanning calorimetry, and centrifugation. The effects of these cosolutes on sol-gel transition varied depending on their molecular weight and stereochemistry, but they generally hindered gel network aging due to increased bulk viscosity. Ribose and allulose inhibited gelatin sol-gel transition, resulting in weak gel strength at all concentrations. Arabinose and raffinose crystallized rapidly at high concentrations, damaging gel structures. At low to medium concentrations (10–30 %), di- and trisaccharides accelerated gelation, but at higher levels, increased bulk viscosity impeded gel percolation, reducing gel strength. In terms of gel-stabilizing forces, the addition of sucrose promoted electrostatic interactions but weakened hydrogen bonding within gel network. This work emphasizes the need to account for gelatin-to-water ratio when evaluating cosolute effects. The findings provide valuable insights for sugar reduction and functionalization for gelled foods.

The cement solidification method serves as an effective approach for the immobilization of heavy metal-containing waste. However, Cr(VI), a highly toxic substance, is inadequately stabilized and solidified within cement pastes, posing a significant risk of leaching. This study innovatively incorporated nano-porous nitrogen-doped carbon (NC), derived from ZIF-8 through carbonization, into the cement containing heavy metals for collaborative disposal mixing with K 2 CrO 4 (HMC-Cr). Subsequently, the hydration behavior, mechanical properties, and solidification mechanism of Cr(VI) in the composite cement pastes were examined. The experimental results revealed that, compared to ZIF-8, NC demonstrated significantly greater positive impacts on the hydration kinetics, compressive strength, and Cr(VI) immobilization capabilities of HMC-Cr cement. Compared with pure HMC-Cr pastes, the 28-day compressive strength of HMC-Cr/NC increased by 16.7 %, and the leaching concentration of heavy metal Cr decreased by 52.5 %. The HMC-Cr/NC pastes exhibited superior Cr(VI) solidification capacity, attributed to the appropriate pore size, excellent nucleation effect, and reduction properties of NC. The primary immobilization forms of Cr in HMC-Cr/NC pastes included CrO 4 2- -AFm, Cr(OH) 3 , and coordination structures involving C-NH. Consequently, NC nanomaterials derived from ZIF-8 serve as effective additives for enhancing the stable immobilization of Cr(VI) in the cement solidification treatment of heavy metal-containing waste.

Transparent superhydrophilic coatings exhibiting underwater superoleophobic behavior have garnered significant interest for their promising functionality in fogging resistance and oil repellent applications. However, the development of such coatings with effective anticrude-oil-fouling properties presents a formidable challenge, as conventional approaches to mitigate high-viscosity crude oil adhesion often compromise optical transparency. Herein, we report a bioinspired “double-defense” strategy that integrates a polydopamine/polyethylenimine-dextran (PDA/PEI-D) hydrogel layer with a biomimetic mineralized magnesium phosphate (MP) layer to construct a hierarchical “sesame cake-like” superhydrophilic coating. This unique architecture demonstrates exceptional crude-oil-repellency and long-term antifogging performance. With the “double-defense” design strategy, the synergistic effect of the second defense hydrogel layer (cake layer) and the first defense MP layer (sesame layer) enhances the hydration capacity of the PDA/PEI-D/MP coating, ensuring superior crude-oil-repellent and antifogging properties. Moreover, the uniformly distributed discrete MP nanoparticles on the PDA/PEI-D/MP coating surface minimize light scattering while maintaining the coating’s optical transparency (>90% transmittance). The “sesame cake-like” PDA/PEI-D/MP coating maintains high transparency and crude-oil-repellent and fogging resistance even after a series of durability tests and can be widely used in underwater optics, microfluidic systems, and oily wastewater treatment.

Efficient lubrication at low concentration has always been the pursuit of mechanical equipment in engineering applications, and breakthroughs for high performance are urgently needed, as well as the consideration of cost and sustainability. Therefore, water-based lubricants have become a crucial and potential lubricating system. Herein, a novel ionic liquid (IL) water-based lubrication system was constructed, achieving superior lubricity and long-term stability, whose optimal anti-friction performance and corrosion resistance are reduced by more than 80 %. More importantly, its versatility (anti-corrosion, strong adsorption, anti-wear and load-bearing) is also essential. Of course, these improved performances are inseparable from the multiple interactions (hydrogen bond, competitive adsorption, electrostatic interaction, tribo-chemistry) between ILs and engineering metal surfaces. More interestingly, the exploration of interaction mechanism inspires more in-depth insights for self-assembly behavior for IL aqueous system at the metal interface. From in-depth insights on lubricating mechanism, the hydration shell induced by polar groups and interfacial tribochemical reaction are predominant in competitive adsorption, which can be inferred from the molecular dynamics simulation data. As far as the interaction force is concerned, the struggle and balance among adsorption energy, hydrogen bond and electrostatic interaction force reveal the synergistic lubrication mechanism of multiple interaction force coupling. Besides, the structure–activity relationship between system composition and performance provides theoretical guidance for its practical engineering application, which also can be expanded as an important theoretical basis and experimental references for aqueous lubrication.

In this study, the 3-Aminopropyltriethoxysilane (APTES) was first grafted onto TiO 2 nanoparticles (APTES-TiO 2 nanoparticles), which were then introduced the membrane surface by reacting with anhydride on the membrane surface and Schiff base reaction with the PEI-TA. There are two types of hollow fiber hybrid membranes with varying nanoparticle distributions were constructed. The influence of hybrid mode on the ability of anti-oil fouling was researched. The results indicated that the PVDF@TiO 2 hybrid membrane has a flux recovery rate of 96.68 % and a total flux decline rate of 15.52 %, indicating a good anti-emulsified oil fouling performance. By characterizing the anti-oil droplets adhesion, water-binding capacity, surface charge of membrane and concentrate system coacervate size, the coalescence ability of the hybrid membrane to the oil droplets and the spreading behavior of oil droplets on the surface were uncovered. Ultimately, the anti-fouling mechanism “hydration layer &rigid layer obstruction-electrostatic coalescence” was proposed, which can reasonably explain the weakness of the interplay between the membrane surface and oil droplets, thus slowing down the attaching and spreading of emulsified oil droplets. This study laid the foundation for developing hybrid membranes with high resistance to emulsified oil fouling ability. The proposed anti-fouling mechanism can provide new ideas for the efficient purification of oily wastewater.

Rapid repair mortar (RRM) is widely used to repair infrastructures, which must achieve high early strength and long-term service. This study investigated the influence of hot/wet harsh environmental conditions on RRM prepared using solid-waste-based sulfoaluminate cement (WSAC). Orthogonal experiments were conducted to obtain the optimized WSAC-based RRM. Then, the impact of simulated harsh conditions (cross-combination of 20/60 °C and 10/40/90%RH humidity) on RRM and synthetic ettringite was studied. High temperature and low humidity restrained the volume deformation and promoted the growth of the later-age compressive strength of the RRM, but reduced the flexural strength. In this case, ettringite lost some water molecules in the Ca–H2O groups and transformed into amorphous meta-ettringite, which retained its needle-rod morphology. A small amount of ettringite decomposed into gypsum, AH3, and Ca(OH)2 under high-humidity conditions, which caused a slight expansion and reduced the compressive strength of the RRM. Fortunately, most ettringite was well protected by the dense RRM matrix, and harsh temperature and humidity conditions could only slowly promote the transformation of ettringite in RRM over a long period. Therefore, short-term rain or hot weather has little effect on the mechanical properties of WSAC-based RRM. This study provides a theoretical basis and data support for the promotion of industrialization of WSAC-based RRM, which is in line with the concept of green and sustainable development.

The cement containing heavy metals for collaborative disposal (HMC) as a low-environmental-load cementitious material still encounters challenges related to temperature-induced cracking due to high hydration heat. In this paper, a paraffin (PA)/metal-organic framework (MOF) composite phase change material (CPCM) with excellent shape stability, thermal storage capacity, and thermal stability was creatively integrated into HMC, aiming to investigate the impacts of CPCM on the hydration heat release behavior. The compressive strength and hydration product evolution of HMC paste mixed with CPCM were also discussed. The experimental results demonstrated that CPCM notably reduced the initial hydration rate (especially the main exothermic peaks) and total hydration heat of HMC, regardless of the hydration temperature. Furthermore, the impact of CPCM on the hydration heat of HMC was found to be positively correlated with the dosage. Additionally, the compressive strength of composite paste decreased and chromium (Cr) leaching content increased due to the addition of CPCM, which can be attributed to the expansion of paste pores. But, the additional inclusion of minute quantities of ZIF-8 significantly ameliorated these negative effects. Moreover, CPCM, ZIF-8, and hydration temperatures did not change the type of hydration products in HMC, but they did affect the amount and microstructure of hydration products. CPCM indeed effectively reduced the hydration heat of HMC, this study offers new insights into the use of phase change materials to mitigate the thermal cracking issue in cementitious materials.

Excess-sulphate phosphogypsum slag cement (ESC) is a clinker-free binder with low carbon footprint, low embodied energy and good corrosion resistance, but slow strength development, known as one of the most serious issues, limits its application in practical engineering. In this regard, in-situ precipitation of ettringite by adding NaAlO 2 (NA) to act as nucleation seeds was proposed in this study. ESC consisting of 45% granulated blast-furnace slag (GBFS), 45% phosphogypsum, and 10% steel slag was designed, and 0.1~4% NA was added as chemical admixture to produce ettringite. Effects of NA on compressive strength, hydration process, microstructure and shrinkage were discussed. Results suggested that 0.1~4% NA significantly improved the compressive strength of ESC paste after 7 d, and 1% NA enhanced the strength by 87.6% at 28 d and 77.5% at 56 d. The reason was that NA could supply Al(OH) 4 - to react with the ions in pore solution of ESC to quickly precipitate ettringite seeds, thus inducing the hydration of ESC and formation of hydrates, and especially the formation of ettringite was greatly promoted. However, NA hardly affected early strength of ESC, since NA reduced liquid alkalinity during ettringite seeds formation, and this is not conducive to early precursor dissolution and hydrate formation.

Despite the clinical success of tricalcium silicate (TCS)-based materials in endodontics, the inferior handling characteristic, poor anti-washout property and slow setting kinetics hindered their wider applications. To solve these problems, an injectable fast-setting TCS/β-tricalcium phosphate/monocalcium phosphate anhydrous (β-TCP/MCPA) cement was developed for the first time by incorporation of hydroxypropyl methylcellulose (HPMC) and β-TCP/MCPA. The physical-chemical characterization (setting time, anti-washout property, injectability, compressive strength, apatite mineralization and sealing property) of TCS/(β-TCP/MCPA) were conducted. Its hydration mechanism was also investigated. Furthermore, the cytocompatibility and osteogenic/odontogenic differentiation of stem cells isolated from human exfoliated deciduous teeth (SHED) treated with TCS/β-TCP/MCPA were studied. The results showed that HPMC could provide TCS with good anti-washout ability and injectability but slow hydration process. However, β-TCP/MCPA effectively enhanced anti-washout characteristics and reduced setting time due to faster hydration kinetics. TCS/(β-TCP/MCPA) obtained around 90 % of injection rate and high compressive strength whereas excessive additions of β-TCP/MCPA compromised its injectability and compressive strength. TCS/(β-TCP/MCPA) can induce apatite deposition and form a tight marginal sealing at the dentin-cement interface. Additionally, TCS/(β-TCP/MCPA) showed good biocompatibility and promoted osteo/odontogenic differentiation of SHED. In general, our results indicated that TCS/(β-TCP/MCPA) may be particularly promising as an injectable bioactive cements for endodontic treatment.

Curcumin (CCM) has many potential uses in anticancer chemotherapy, but its low water solubility poses a major problem, preventing its translation into clinical use. TPGS is a water-soluble derivative of vitamin E that acts as a surfactant with the ability to form micellar nanoparticles in water. More importantly, TPGS acts as a potent antioxidant that can neutralize intracellular reactive oxygen species (ROS). In this study, we solubilized CCM with TPGS using thin-film rehydration to prepare aqueous formulations containing CCM at clinically relevant concentrations. We found that the minimal TPGS:CCM ratio for producing nanoparticles was 5:1 (w/w): at or above this ratio, stable nanoparticles formed with an average particle diameter of 12 nm. CCM was released from TPGS/CCM micelles in simulated colonic and gastric fluids. These TPGS/CCM nanoparticles were shown to decrease intracellular ROS levels and apoptosis and inhibited migration of HT-29 human colon cancer cells more potently than free CCM. Pharmacokinetic analysis showed TPGS/CCM to be more bioavailable than free CCM after oral administration to rats. Our results suggest that TPGS/CCM may increase therapeutic efficacy of CCM against colon cancer and merits further investigation in a clinical setting.

Generally, high volume fly ash would considerably reduce the early strength of cement-based materials, and because of this disadvantage, the added amount of fly ash in steam-cured precast concrete is very limited. In this study, an attempt to enhance the early strength of steam-cured cement-high volume fly ash (40 wt%, CHVFA) system has been done with addition of nano-SiO 2 (NS) and sodium sulfate (SS). Effect of these two chemicals on hydration, pore structure, and microstructure of interfacial transition zone (ITZ) were investigated. The results show that both NS and SS can improve the compressive strength, and the reason is mainly because these two chemicals can accelerate the hydration of cement minerals and can also hasten the pozzolanic reaction of fly ash. By contrast, because of the high activity of pozzolanic reaction and the filling and nucleation effects, NS has much stronger effect on refining pore structure and promoting the hydration of cement; while SS can exert much stronger effect on accelerating the hydration of fly ash than that of NS. An interesting thing can also be seen that with co-doped NS-SS, the enhancement in compressive strength is much stronger than that of the sum of these single systems with the same dosage, indicating that NS and SS can exert the synergistic effect; this effect is involved in the accelerated hydration of CHVFA, the refined pore structure, and the improved microstructure of ITZ. Such results would be expected to provide guidance on enhancing the early strength of steam-cured precast concrete with high volume fly ash in practical engineering.

Although the titanosilicate zeolite catalyzed one-pot oxidative hydration of ethylene with hydrogen peroxide (H 2 O 2 ) to ethylene glycol (EG) takes advantages of step-saving and facile operation, both H 2 O 2 utilization efficiency and EG yield are relatively low. In the present work, Sn-doped Ti-MWW zeolites, named Sn-Ti-MWW, were developed for this oxidative hydration, showing the much higher H 2 O 2 utilization efficiency and EG yield, compared to Ti-MWW. The extensive characterizations of Sn-Ti-MWW zeolites, in combination with Density Functional Theory (DFT) calculations, verify that the doping of Sn into Ti-MWW leads to the higher electropositivity of the Ti species, resulting in the stronger acidity of the zeolite, which is helpful to the H 2 O 2 utilization and EG production. In addition, although the catalyst deactivation is observed due to the deposition of the bulky byproducts onto the active sites and/or into the zeolite micropores, the simple calcination of the used catalyst readily restores its catalytic activity. Therefore, it is anticipated that the developed Sn-Ti-MWW catalyst might be applicable in the one-pot oxidative hydration of ethylene with H 2 O 2 to EG industrially.
