Lactic acid (LA) is a crucial platform chemical for biodegradable plastics, primarily produced via microbial fermentation. However, the conventional purification process via calcium salt precipitation generates substantial calcium sulfate waste. This study proposes a novel solvent extraction method using di-(2-ethylhexyl) phosphoric acid (P204) to extract calcium ions from calcium lactate, thereby releasing LA into the aqueous phase. Under multistage counter-current conditions, calcium extraction and stripping efficiencies exceeded 99.7 % and 98.5 %, respectively, yielding a high-purity CaCl 2 ·2H 2 O by-product instead of calcium sulfate. The process demonstrated broad applicability to calcium salts of weak organic acids (p K a > ∼3.40). Mechanistic studies revealed a 2:1:1 (P204:Ca:LA) coordination complex. Green chemistry assessment confirmed the process’s environmental sustainability and practical viability. This work presents an efficient strategy for LA production that avoids calcium sulfate waste, contributing to greener biorefinery processes.

Jasmine green tea (JGT), a distinctive Chinese tea product, derives its unique aroma via the adsorption of volatiles from jasmine flowers onto green tea-base tea (GBT). To identify the key odor-active volatiles in JGT, sensomics and chemometrics were employed, with GBT as the control. Sensory evaluation showed that GBT possesses a clean, fresh, and tender aroma, whereas JGT is characterized by a jasmine-like and refreshing scent. 35 and 31 candidate key odor-active compounds were identified in GBT and JGT, respectively, using aroma extract dilution analysis (FD > 16), and odor activity value analysis (OAV > 1). Aroma recombination, omission, and addition tests confirmed 13 key odor-active volatiles in JGT. Among these, α -farnesene and methyl salicylate were found to be the primary contributors to the jasmine-like and refreshing aromas, respectively. This study provides a theoretical reference for deeply understanding the molecular basis of JGT's aroma characteristics.

Micro quantum-dots light-emitting diodes (Micro-QLEDs) is a pivotal evolution in QLEDs displays. Inheriting the advantages of conventional QLEDs, such as wide color gamut, narrow emission bandwidth, and self-emissive properties while achieving ultra-small size. However, current fabrication methods for Micro-QLEDs are limited by complex processing, efficiency degradation, and high manufacturing costs, which hinder their commercialization. In this study, we employ an all inkjet-printing (AIJP) approach to overcome the compatibility limitations of conventional inkjet processes. In particular, A self-emissive red Micro-QLEDs with the structure ITO/PEDOT:PSS/TFB/QD/ZnO/Ag by stacking 5-soluble layers without intermixing. Its size has been scaled down to 30 μm—the smallest light-emitting area QLEDs for AIJP reported to date. The red Micro-QLEDs achieves the maximum external quantum efficiency (EQE) of 7.35% and a current efficiency of 11.19 Cd/A and the highest brightness of 61,377.41 Cd/m 2 . Accurate printing and uniform film formation were realized through systematic ink formulation optimization. The AIJP process offers significant advantages, including simplified fabrication, high material utilization, and independence from photolithography. This work represents a critical step toward the industrial production of full-color Micro-QLEDs displays and demonstrates strong potential for applications.

This pioneering study investigated the effects of sip volume on sensory perception and drinking comfort during the consumption of Jiangxiangxing Baijiu (JB). Six sip volumes (6, 9, 12, 15, 18, and 20 mL) were tested with 30 participants (15 males and 15 females). Results revealed gender-specific preferences: females tended to prefer sip volumes of 9–12 mL, while males were more likely to favor 18 mL. Using Temporal Dominance of Sensation (TDS) and Check-All-That-Apply (CATA) methods, it was found that oral sensations of sweetness and sauce flavor, as well as post-pharyngeal sensations of “smoothness,” “mellowness,” and “lingering aftertaste,” enhanced drinking comfort. In contrast, oral sensations of spiciness and bitterness, along with post-pharyngeal sensations of “pungency,” “thinness,” “blandness,” and “momentary aftertaste,” impaired comfort. Notably, females may place greater emphasis on oral perception, whereas males could focus more on post-pharyngeal sensations. A novel flavor analysis identified 20 key compounds that influence JB perception. The insights from this research provide valuable contributions to improving the drinking experience of JB.

The recovery of valuable vanadium (V) and molybdenum (Mo) from spent residue hydrogenation catalysts is crucial due to their high content. However, their efficient separation from the catalyst leaching solution remains challenging. This study investigates a single-stage extraction and stripping process for V and Mo recovery. Under the optimal conditions with 20 vol% of the extractant Aliquat 336, 10 vol% of the phase modifier n-octanol, and an initial aqueous phase pH of 1.0, V and Mo could be effectively extracted, with a distribution ratio of V being 7.02 and that of Mo greater than 1000. The separation factors of V relative to other impurity elements exceeded 360, while those of Mo with respect to impurity elements were greater than 10,000. Afterwards, selective stripping of V was achieved based on its valence state change using an ascorbic acid (VC)-H2SO4 solution. Mo was subsequently stripped with an NH4HCO3 solution. Applied to an actual leaching solution, this process achieved extraction efficiencies over 99.9% for both metals via a four-stage extraction process, with the co-extraction of impurities below 4.50%. A three-stage stripping with 0.3 mol/L VC–0.5 mol/L H2SO4 yielded V stripping efficiency over 99.9% andminimal Mo costripping efficiency of 1.22%. Subsequently, 99.9% of the retained Mo was recovered using NH4HCO3. Therefore, this study provides an efficient strategy for V and Mo recovery, which has significant practical implications for the sustainable management of spent catalysts.

Phthalate plasticizers are the most commonly used plasticizers for soft PVC, but their composite materials are highly prone to cracking in low-temperature environments, leading to significant economic losses. Enhancing the cold resistance of plasticizers may be key to solving this issue. Therefore, this study employs dioctyl phthalate (DOP) as the primary plasticizer and synergistically blends it with the synthesized cold-resistant plasticizers dioctyl adipate (DOA) and dioctyl sebacate (DOS). Experimental results demonstrate that the addition of DOA and DOS significantly improves the low-temperature toughness of PVC/DOP composite films. For instance, at −20°C, the elongation at break of PVC/DOP/DOA and PVC/DOP/DOS increased by 48% and 42%, respectively, compared to PVC/DOP. Similarly, the glass transition temperatures of the compounding film are also higher than those of PVC/DOP. Migration resistance tests indicate that blending DOP with DOA or DOS can slow the migration rate of both DOS and DOA within the resin. Additionally, low-temperature in situ Raman spectroscopy is employed to investigate structural changes in DOP/PVC films under extreme cold conditions. DOP gradually precipitates from the matrix phase and forms crystalline structures on the film surface under low temperatures. This leads to PVC plasticization failure, resulting in brittle fracture.

To address the technical bottleneck of declining hydrophobicity in finely ground minerals that leads to low recovery of traditional hydrocarbon oil collectors, this study utilized computational simulations to design and synthesize a novel collector. Simulation calculations showed that dodecyl xanthogenic acid (DXA-C12) had a comprehensive adsorption effect on both the “basal” and “edges” of molybdenite. Micro-flotation tests showed that DXA-C12 had significant flotation advantages for micro-fine grained molybdenite compared with the traditional kerosene and xanthate combined collector. DXA-C12 interacted with the “basal” and “edges” of molybdenite through hydrophobic and chemical forces, respectively. The DXA-C12 carbon chain drove the interaction with the “basal” and adsorbed in a tiled form. In contrast, C=S supplied electrons to the Mo atoms in “edges”, forming adsorption in an upright form. For the actual micro-fine grained molybdenum ore with a particle size of −38 μm accounted for 97 % and Mo grade of about 4.00 %, using DXA-C12 as the collector could obtain the concentrate with Mo grade and recovery of 39.099 % and 99.68 %, respectively. The study provided a novel collector for micro-fine grained molybdenum ore, and had an important reference significance for the development of other new types of collectors.

Driven by surging global lithium demand, highly selective lithium separation from magnesium-rich brines is urgently required. This work systematically investigated the structure–performance relationship of four aryl-substituted phosphates (TOP, DPOP, IPPP, TPP). Moderate aryl substitution widened the coordination difference between Li + and Mg 2+ through electron-withdrawing effects, and DPOP exhibited the optimal balance of extraction capacity and selectivity. A ternary synergistic extraction system was fabricated with DPOP as the primary extractant, P204 to immobilize Fe 3+ , and eco-friendly diethyl succinate (DES) as a polar modifier. DES inhibited third-phase formation at DPOP contents of 10–50 vol.% and produced synergistic solvation via carbonyl groups. Under optimized conditions, the single-stage Li + extraction efficiency achieved ∼73%, and the Li/Mg separation factor reached 1630, nearly 80 times that of the traditional TBP–FeCl 3 system. Synergistic coordination of P204 and DES stabilized Fe 3+ in the organic phase, realizing quantitative lithium stripping with deionized water and avoiding concentrated acid and saponification. The organic phase maintained over 80% extraction efficiency after ten cycles. Slope analysis and FT-IR confirmed the extracted complex LiFeCl 4 •2DPOP•0.1DES. This work transforms DPOP into a sustainable, low-cost, closed loop industrial solution for lithium recovery from high Mg/Li brines.

BACKGROUND Pretreatments can markedly influence the aroma of canned Antarctic krill ( Euphausia superba ) and alter sensory perception, yet sensory-validated chemical evidence for interpreting pretreatment-driven aroma differences remains limited. This study aimed to identify and validate the key odorants associated with pretreatment-driven aroma differences in canned Antarctic krill, thereby providing flavor-relevant evidence for pretreatment comparison and optimization. RESULTS Quantitative descriptive analysis and E-nose pattern recognition showed clear pretreatment-dependent aroma differences. Aroma-active compounds and pretreatment-driven changes were characterized by gas chromatography–olfactometry–mass spectrometry and prioritized using detection frequency (DF) and flavor dilution (FD) criteria, targeted quantification and odor activity value (OAV) calculation. Forty-eight volatile organic compounds were detected, among which 13 odorants met the criteria of DF ≥ 3, FD ≥ 8 and OAV ≥ 1. Aroma recombination reproduced the sensory profile of the pretreatment associated with the strongest shrimp-like and briny notes, and omission experiments combined with triangle tests confirmed trimethylamine, ( Z )-4-heptenal, 1-octen-3-ol, nonanal and 1-penten-3-ol as pivotal contributors ( P < 0.05). Salt soaking followed by blanching shifted the sensory profile toward stronger shrimp-like and briny notes, consistent with changes in the key odorant set. CONCLUSION The verified odorants provide practical indicators for comparing pretreatments and selecting conditions that improve aroma quality in canned krill. © 2026 Society of Chemical Industry.

ZTA/Cr 2 O 3 ceramics were fabricated by gelcasting via gelcasting followed by pressureless sintering. The effects of pH, dispersant content, ball-milling time, solid loading, and Cr 2 O 3 content on slurry rheological properties, green body properties, sintering densification behavior, and mechanical properties were investigated. The addition of Cr 2 O 3 effectively decreased slurry viscosity and improves flowability, facilitating the preparation of high-solid-loading slurries. The green body relative density and flexural strength reached optimum values at a solid loading of 54 vol%, reaching 54.83% and 19.7 ± 0.27 MPa, respectively. After sintering at 1600 °C for 3 h, the optimum mechanical properties were obtained at a Cr 2 O 3 content of 0.4 vol%. The Vickers hardness, flexural strength, and fracture toughness were 17.17 ± 0.26 GPa, 581.22 ± 9.20 MPa, and 6.59 ± 0.32 MPa m 1/2 , respectively. Compared with Cr 2 O 3 -free ZTA ceramics, the hardness, flexural strength, and fracture toughness increased by 5.5%, 17.58%, and 10.75%, respectively. The enhanced mechanical properties are mainly attributed to the synergistic effects of the solid-solution incorporation of Cr 3+ in the α-Al 2 O 3 lattice, the resulting changes in lattice parameters, grain refinement, improved densification, and enhanced stability of the t-ZrO 2 phase. Furthermore, complex-shaped ZTA/Cr 2 O 3 ceramic components were successfully fabricated, showing no visible defects and uniform shrinkage after sintering, providing useful guidance for the near-net-shape fabrication of high-performance ceramic components.

Hemoperfusion is an effective technique for removing low-density lipoprotein (LDL) from the bloodstream, with the performance of the adsorbent critical to its efficacy. This study innovatively introduces carbonized polymer dots (CPDs), which exhibit excellent biocompatibility and structural versatility, as a new functional ligand in hemoperfusion. A novel hemoperfusion adsorbent was prepared using cellulose microspheres as the support material. Here, we synthesized highly negatively charged CPDs using a hydrothermal method facilitated by nitric acid in the presence of citric acid and p-aminosalicylic acid. This process resulted in a stable zeta potential of −61.0 mV at physiological pH. Incorporating CPDs onto cellulose microspheres enhanced their negative charge from −1.22 mV to −31.0 mV, significantly improving LDL adsorption capacity to 80.3 ± 1.2 mg/g, with a removal rate of 80.3 ± 1.2%, which is 5.7 times greater than high-density lipoprotein (HDL). Furthermore, the introduction of CPDs improved the hemocompatibility of cellulose microspheres, resulting in a low hemolysis rate of 0.81% and minimal cytotoxic effects. FTIR and XPS characterization confirmed that the CPDs contain carboxyl and nitro groups, enhancing their negative charge properties. This research presents a new class of functional ligands for hemoperfusion adsorbents, indicating potential advancements in blood purification technologies.

The usage of electronics has led to the issue of electromagnetic wave pollution, and the demand for materials that can absorb electromagnetic waves is increasing. The longevity of materials may be impacted by damage caused during use. Here, a composite strategy with efficient electromagnetic wave absorption and self-healing through induction heating is proposed. Ni/PUF/PU@ER (NPPE), Cu/Ni/PUF/PU@ER (CNPPE), and Ni/PANI/PU@ER (NPAPE) microcapsules with magnetic and conductive characteristics were prepared by interface polymerization, in situ polymerization, and electroless plating methods. Their superior mechanical and thermal durability guarantee the long-term stability of the healing agent. The minimum reflection loss of the composite with NPAPE is –54.62 dB at 1.85 mm, and the effective absorption bandwidth (EAB) is 3.95 GHz. Additionally, the EAB reaches 4.32 GHz at 1.93 mm, surpassing the RL min and EAB values of the majority of similar materials. Due to the exceptional electromagnetic synergy of NPAPE, the composite exhibits the most outstanding induction heating performance. The material reaches 68.3 ° C within 10 min, which is higher than the temperatures of the other two materials. Furthermore, the crack area of the composite significantly reduces, demonstrating excellent quick self-healing characteristics for damage. This novel strategy is conducive to promoting the development of the circular economy and can introduce a worthwhile research direction into the field of electromagnetic wave absorption.
