Solid-phase sintering (SS) is a widely used method for synthesizing oxides due to its simplicity and scalability. However, it typically relies on organic liquids as grinding media, resulting in higher costs and environmental pollution. This study proposes a boiling water-assisted solid-phase sintering (BWA-SS) method for synthesizing oxide electrolyte materials, in which water is used as the grinding medium and the precursor slurry is directly sintered, providing an eco-friendly process. More importantly, finite element analysis shows that this method prevents the uneven sedimentation of raw material particles by secondary dispersion caused by the vapor mass flux gradient in boiling water. Using this organic-free method, the pure Li7La3Zr2O12 (LLZO) solid electrolyte is successfully synthesized, achieving a high ionic conductivity (σi) of 6.22 × 10–4 S/cm, which is comparable to that of LLZO solid electrolyte material produced by the conventional SS method. The assembled Li/LLZO/Li symmetrical cell exhibits stable cycling for 3000 h at a current density of 0.1 mA/cm2. This method has also been successfully extended to the synthesis of other solid electrolytes (LiTa2PO8, LTPO) and cathode materials (LiNi0.8Co0.1Mn0.1O2, NCM811), demonstrating potential for clean preparation of various oxide materials.

Ginkgo biloba leaves (GBLs) contain high phytoconstituents, but ginkgolic acids (GAs, the main toxic compound in GBLs) have limited its applications. Processing Ginkgo biloba dark tea (GBDT) using fixation technology could decrease the toxic compounds; retain flavonoids, ginkgolides, and bilobalide; and improve the product quality. For the first time, various thermal fixations (hot air fixation [HAF], iron pot fixation [IPF], and boiled water fixation [BWF]) followed by rolling, fermentation, and drying were applied to produce GBDT. A comprehensive analysis of the toxicants (GAs), main bioactive compounds (ginkgolides and bilobalide, flavonoids, antioxidants, and phenolic profiles), and product qualities (moisture content, reducing sugar [RS], free amino acids [FAAs], enzyme activity, color properties, antioxidant capacity, etc.) were evaluated. The results revealed that thermal fixations BWF and HAF significantly reduced the GA contents (41.1%–34.6%). Most terpene lactones showed significant differences in control, IPF, and HAF. The HAF had lower total flavonoid content (TFC) than BWF and IPF. The control group (unfixated) had the highest toxic components (GA), terpene trilactones, and TFC compared with various fixations. Adding different fixations to rolling, fermentation, and drying had various impacts on GBDT, and principal component analysis supported the results. Among four thermal fixations, HAF yielded the best results in RS, FAA, total phenolic content, and antioxidant activities, while IPF had the highest TFC. BWF had the lowest content for GA. In conclusion, HAF (6) was chosen as the best technique for producing GBDT since it preserved GBDT's bioactive components while lowering its toxic components.

In this study, the novel long-chain active composite rejuvenators (NLCACRs) were composed of long-chain active rejuvenators (LCARs) and aromatic hydrocarbon oil (ArO). Surface free energy method (SFE method), boiling water test method (BWT method) and related parameters were used to evaluate the effect of NLCACRs on interfacial adhesion between aged SBS modified asphalt (ASBS-MA) and granite, and preliminarily predict the moisture sensitivity of asphalt-aggregate system. The results indicated that NLCACRs could increase the surface free energy of ASBS-MA, and the increased range varied with the composition and structure of NLCACRs. The NLCACRs could not only supplement the light components lost by asphalt during aging, but also reconstruct the damaged structure of aged SBS, so they were more effective for the recovery of cohesion work of ASBS-MA. NLCACRs could significantly increase the interfacial adhesion between ASBS-MA and acid granite, and decrease the moisture sensitivity of rejuvenated SBS modified asphalt (RSBS-MA)-granite system. And the results of the BWT method indicated that long-term aging decreased the adhesion grade between SBS modified asphalt and granite from G4 to G2. NLCACRs could restore the adhesion grade of ASBS-MA and granite to the level of original SBS modified asphalt. The comprehensive analysis of the influence of NLCACRs on the interfacial adhesion between ASBS-MA and aggregate showed that the theoretical law (SFE method) was consistent with that of the actual (BWT method). This study could help to explore the influence of NLCACRs on the moisture stability of aged SBS modified asphalt mixture and provide the theoretical basis for its application in practical engineering.

The odor-active compounds in Fu-brick tea and their release behaviors during boiling-water were studied. Fifty-one odor-active compounds were identified, and their release behaviors were identified by continuously recovering 16 sections of condensed water combined with sensory, instrumental, and nonlinear curve fitting analysis. The odor intensities of condensed water and the concentrations of odor-active compounds could be significantly fitted ( p < 0.01) to power-function type curves. Hydrocarbons showed the fastest release rate, while organic acids showed the slowest. The release rates had very little correlation with their concentrations, molecular weights, and boiling points. Most odor-active compounds (≥70 %) released need to evaporate more than 24 % of the added water during boiling-water extraction. Meanwhile, on the basis of odor activity value (OAV) calculation, the aroma recombination experiments were performed to explore the odor-active compounds that made major contributions to the formation of the aroma profile of each condensed water.

PVAc-based inverted core/shell (ICS) structured latex adhesive with improved water- and heat-resistance was prepared by a copolymerizing-grafting sequential reaction approach. The sequential reaction process combines the function of a copolymer layer and an active grafting site to controllably achieve the thermodynamic non-equilibrium ICS morphology with hydrophilic poly(vinyl acetate) (PVAc) cores and hydrophobic polystyrene (PS) shells. The difference between the sequential reaction approach and the chemical grafting method was explored. Structured latex particle morphology , transferring from strawberry-like particles, over particles with large and irregular PS protuberances, to nearly spherical particles with a smooth surface, was microscopically visualized by changing the amount of butyl acrylate (BA) in the PVAc copolymer cores. The heat- and water-resistant bonding of PVAc-based adhesives on wood blocks were evaluated by shear strength at both dry and wet conditions, as well as the boiling water failure time. The results showed that a significant improvement of water- and heat-resistance, especially for boiling water resistance, was successfully obtained. This novel approach paves a way for controlled design and manufacture of high-performance emulsion adhesives through tailoring particle morphology.

Efforts made to efficiently fabricate traditional superhydrophobic coating have always faced limitations such as high cost, recontamination, and sophistication. An artificial superhydrophobic copper stearate (CS) polydimethylsiloxane (PDMS) coating was fabricated to achieve the transition of a water-adhesion surface to a water-repellent surface. This coating formed superhydrophobic surfaces in different types of substrates through dipping, spraying, and brushing, and demonstrated excellent water repellency, low contact angle hysteresis, and weak adhesive forces after exposure to tape-peeling cycles (VHB, 3 M), abrasion cycles, acid/alkali solutions, corrosive solutions, freezing water, and boiling water. Additionally, experiments were conducted on potential applications of the superhydrophobic coating in oil/water separation, self-cleaning, and anti-corrosion.

Polyhydroxy flavonols readily degraded during thermal processing. In this study, the UPLC-Q-tof-MS/MS was applied to explore the stability of dietary polyhydroxy flavonols, myricetin, kaempferol, galangin, fisetin, myricitrin, quercitrin and rutin, in boiling water. The decomposition of flavonols was mainly caused by the heterocyclic ring C opening to form simpler aromatic compounds. The degradation products mainly included 1,3,5-benzenetriol, 3,4,5-trihydroxybenzoic acid, 2,4,6-trihydroxybenzoic acid and 2,4,6-trihydroxybenzaldehyde, etc. Compared with myricetin with a pyrogallol-type structure on the ring B, the glycoside in myricitrin slightly affects the stability. However, the glycosides in rutin and quercitrin dramatically improved the stability in water. During the boiling process, flavonols underwent a series of chemical reactions, such as hydroxylation, dehydroxylation, deglycosidation, deprotonation, and C-ring cleavage.
