Sustainable aviation fuels (SAFs) are mainly composed
of cycloalkanes,
paraffins, and aromatics, representing an inevitable alternative to
conventional fossil fuels. Alcohols and phenolic compounds act as
critical precursors to produce branched alkanes and cycloalkanes,
the major constituents of sustainable aviation fuel. Biomass is primarily
composed of C 6 sugar, and aromatic structures, which can
be employed for the production of phenolics and alcohols. However,
the direct thermal conversion of biomass results in poor selectivity
toward phenolic and alcoholic products. Based on the structural characteristics
of three typical biomass feedstocks, γ-valerolactone (GVL) pretreatment
of biomass coupled with thermal conversion to produce phenolics and
alcohols was proposed. The results showed that GVL pretreatment could
effectively decompose corncob, poplar, and pine into cellulose-rich
fractions (C 6 -based structures) and lignin-rich fractions
(aromatic structures). The highest ethanol yield of 24.4 wt % was
obtained by the catalytic hydrogenolysis of the corncob-based cellulose-rich
fraction over the Ni@C catalyst. The highest relative content (54.1%)
of phenols from fast pyrolysis of lignin-rich fractions extracted
from poplar was achieved. This work demonstrates an advanced process
to achieve a directional conversion of biomass to precursor production
of SAFs.

Rare-earth (RE) doping has proven to be effective in enhancing the luminescent and optoelectronic properties of halide perovskites (HPs). However, the growth of RE-doped halide perovskite single crystals remains challenging. Herein, we successfully synthesized nine distinct MAPbBr3:RE (RE = Yb, Eu, Tb) single crystals (6–8 mm in size, RE/Pb = 0.008–0.053%) through systematic optimization of RE reagents, growth temperature, and solution concentration. Structural and optical characterization revealed RE-induced lattice expansion and band gap modulation, confirming the effective incorporation into the perovskite lattice. Furthermore, RE doping significantly improved the charge transport properties of MAPbBr3 single crystals. After doping Yb into MAPbBr3 (Yb/Pb = 0.013%), the trap density decreased from 9.2 × 109 to 2.5 × 109/cm3, carrier mobility increased from 59 to 799 cm2/(V s), and carrier lifetime increased from 199 to 2766 ns. These enhancements translated to exceptional γ-ray detection performance, with the energy resolution (ER) value for 241Am (59.5 keV) improved from 11.0% (for pristine MAPbBr3) to 6.3% (MAPbBr3:Yb) under a 5 V bias. This work not only establishes RE doping as a powerful strategy for optimizing the properties of halide perovskite semiconductors but also opens new avenues for the development of advanced radiation sensing materials.

Biaxially oriented polypropylene (BOPP), a state-of-the-art commercially benchmark dielectric material for thin-film capacitors dominating modern electrostatic capacitor technologies, suffers from performance degradation above 85 °C. To address the limitation, a scalable strategy combining bulk γ-ray irradiation and surface nano-coating is developed to enhance the high-temperature capacitive energy storage performance. At 125 °C, the irradiated BOPP film coated with rectorite nanosheets (RNs) achieves a high energy density of 2.8 J cm −3 at 500 MV m −1 with 95% efficiency, representing a 250% enhancement relative to pristine BOPP and outperforming reported PP-based dielectrics. Notably, the composite film sustains 1.8 J cm −3 energy density at 98% efficiency through 30,000 charge-and-discharge cycles under 400 MV m −1 at 125 °C. Experimental and theoretical analyses reveal the underlying mechanism that the negatively charged and wide-bandgap RNs suppress charge injection, while the polar groups in BOPP introduced by γ-irradiation provide deep-energy traps to block the movement of charge carriers within the dielectric. This optimization approach establishes a design paradigm for high-temperature polymer dielectrics and brings new insights into bulk and interfacial engineering.

Fruits and vegetables are highly susceptible to quality degradation, resulting in substantial economic losses. In this study, an edible γ-CD-MOF was prepared using an ultrasound-assisted method and employed as a carrier for oregano essential oil (OEO) to fabricate OEO@CD-MOF nanoparticles. These nanoparticles were subsequently incorporated into zein protein to develop a Zein-OEO@CD-MOF composite film. The incorporation of 5% OEO@CD-MOF into the zein matrix significantly enhanced the composite film's mechanical properties, ultraviolet resistance, water vapor barrier, and antioxidant property. Furthermore, the Zein-OEO@CD-MOF composite film was applied for the preservation of strawberries, cherry tomatoes, and blueberries. Results demonstrated that the composite film effectively mitigated nutrient loss in the fruits, thereby significantly extending their shelf life. Therefore, the Zein-OEO@CD-MOF composite film represents a sustainable and efficient active packaging material with substantial potential for practical applications in food preservation.

Gas-phase dehydrocyclization of 1,4-butanediol (BDO) is an environmentally benign and sustainable route for γ-butyrolactone (GBL) production. In this work, a series of Cu-M (M = Zn, Cr) catalysts was synthesized via coprecipitation and evaluated in a fixed-bed reactor for GBL yield. Under the reaction conditions of 240 °C, 0.1 MPa, and a weight hourly space velocity (WHSV) of 2 mL∙g −1 ∙h −1 , 99.62% of BDO conversion, 99.72% of GBL selectivity, and 2.22 mol GBL ·g catalyst -1 ·h −1 of CBL formation rate were achieved over CuZnCr-600 catalyst, which is higher than reported studies. Long-term test proved that this catalyst could operate over 100 h without any deactivation. Combined microscopic and spectroscopic analysis showed that the calcination conditions affected the surface acidity-basicity of catalysts by changing the CuO content and the strength of the Cr-O bond. The Cu-M compositions significantly influenced the morphology and the electronic properties of Cu species. The incorporation of Cr led to the formation of CuCr 2 O 4 spinel structure, which not only enhanced Cu dispersion but also improved the catalysts’ resistance to sintering. The presence of Zn restrained the phase-transformation of CuCr 2 O 4 from cubic to tetragonal, which ensured the reducible property of CuCr 2 O 4 even under high-temperature calcination. Furthermore, modulating the calcination temperature and the Cu-M compositions maintained an optimal Cu + /Cu 0 ratio under reaction conditions. All these issues contributed to the high yield of GBL and the prolonged lifetime of catalysts.

The folding behavior of guest molecules plays a critical role in determining host-guest interaction patterns in supramolecular systems. This study presents a systematic investigation of how amino acid side chains control the folding conformations of pyrene-based guests and thereby direct their recognition by γ-cyclodextrin. Through comprehensive analysis, we demonstrate that extended conformations enable stable inclusion within the cyclodextrin cavity, as evidenced by the emergence of a characteristic excimer fluorescence band at 480 nm, while progressively folded structures lead to weakened interactions due to steric hindrance. The self-shielding effect in rigidly folded molecules, driven by intramolecular π-π stacking between the pyrene core and the aromatic side chain, completely suppresses host-guest complexation. This mechanistic insight is quantitatively supported by molecular dynamics simulations, which reveal that the spatial dimensions of the folded conformers exceed the capacity of the γ-cyclodextrin cavity. These findings establish molecular folding as a key design parameter for programming supramolecular recognition, providing new strategies for controlling molecular assembly through side chain engineering.

Poly(L-lactic acid) (PLLA) microspheres are widely used in aesthetic and regenerative medicine to promote collagen remodeling, but their efficacy and long-term safety lack sufficient experimental data. In this study, a poly(γ-glutamic acid)-thickened PLLA microsphere formulation (PLLA–γ-PGA) was developed, and its biocompatibility and efficacy were evaluated in an aged mice model induced by subcutaneous injection of D-galactose combined with UV irradiation. As a result, PLLA–γ-PGA significantly enhanced dermal fibroblast activation, promoted sustained tissue remodeling and elicited milder inflammatory responses without observable adverse effects, outperforming marketed hyaluronic acid (HA) fillers and PLLA–carboxymethyl cellulose sodium (PLLA–CMC) formulations. These findings present PLLA–γ-PGA as a safe and efficacious regenerative material, providing robust preclinical evidence to support its translational potential for long-term skin rejuvenation.

The selection of appropriate in vitro inflammatory models is critical for mechanistic studies of neuroinflammation and the screening of anti-inflammatory therapeutics. Lipopolysaccharide (LPS) combined with interferon-γ (IFN-γ) and LPS combined with adenosine triphosphate (ATP) are widely used to induce microglial inflammation; however, their distinct phenotypic characteristics and optimal applications have not been systematically compared. In this study, we combined transcriptomic profiling with functional assays to compare these two inflammatory paradigms in BV2 microglia. Our results showed that both models activated the chemokine–cytokine inflammatory network and induced the production of inflammatory mediators and chemokines, but exhibited distinct molecular and functional biases. LPS/IFN-γ stimulation preferentially upregulated genes such as Lcn2 , Ccl2 , Upp1 , and Pim2 , which are associated with innate immune activation, chemokine-mediated inflammatory responses, and cell survival signaling, and was accompanied by marked increases in NO and TNF-α production. In contrast, the LPS/ATP model preferentially upregulated genes associated with ECM/cell adhesion, inflammatory and cellular homeostatic regulation, oxidative stress, and calcium-dependent secretion, including Thbs1 , Thbd , Srxn1 , Syt7 , and Procr . Functionally, this model exhibited more pronounced IL-1β maturation and release, relatively lower NO production, and greater mitochondrial dysfunction and cell injury. Pharmacological inhibition of NLRP3 with MCC950 significantly attenuated ATP-induced IL-1β maturation, supporting the involvement of the NLRP3 inflammasome in the LPS/ATP model. Overall, the LPS/IFN-γ model is more suitable for investigating the NO/iNOS–TNF-α axis, IFN-γ-mediated synergistic pro-inflammatory responses, and classical pro-inflammatory activation, as well as for screening anti-inflammatory agents. In contrast, the LPS/ATP model is more appropriate for studying IL-1β maturation and release, NLRP3 inflammasome activation, mitochondrial damage, and inflammation-related cell death, as well as for screening inflammasome inhibitors. Our findings provide an empirical framework for rational model selection in microglial inflammation research.

A composite material synthesized from HCl-treated red mud and γ-Al 2 O 3 (Al 1 HRM 2 ), was developed to enhance CF 4 decomposition in our previous study. However, its catalytic performance requires improvement, as it suffers from poor stability. In this study, the low-cost and anti-HF-corrosive CaO was utilized to further boost the material's CF 4 decomposition efficiency and stability. Specifically, decomposition efficiency and stability increased by 30% and 2.25 times than that of Al 1 HRM 2 , respectively. At the microscopic level, it was observed that after CaO uniformly distributed across the catalyst surface, it enhanced the Al-O (Al-O-Al) stretching vibration, increased the number of oxygen vacancies, and simultaneously prevented the phase transition from γ to α. Additionally, CaO intensifies the characteristic peaks of strong L-acid sites, enhancing their CF 4 adsorption capacity and strength. Specifically, Al Ⅲ sites facilitate C-F bond cleavage to form AlF 3 , which undergoes fluorine-oxygen exchange with CaO to produce CaF 2 . This process effectively inhibits F + occupation of γ-Al 2 O 3 active sites, thereby promoting CF 4 decomposition. This study utilizes RM as a high-performance material for CF 4 pollution control, achieving the goal of treating waste with waste across the aluminum industry supply chain. It provides a new technological foundation for purifying difficult-to-treat Perfluorocarbons greenhouse gases.

Constructing thermally durable single-atom catalysts resembling mononuclear homogeneous catalysts for the hydrosilylation industry is usually challenging. Herein, a stable single-atom catalyst with Pt single atoms anchored on a nonreducible and industrially fundamental γ-Al2O3 support (Pt1/γ-Al2O3) was fabricated using atomic layer deposition technology. The catalyst enabled anti-Markovnikov hydrosilylation under room-temperature and solvent-free conditions and exhibited activity exceeding that of the homogeneous Karstedt’s catalyst. The Pt1/γ-Al2O3 catalyst not only afforded a broad substrate scope in high yields, encompassing various alkenes and alkynes, but also exhibited robust stability and recyclability. Extended X-ray absorption fine structure and X-ray absorption near-edge structure analyses confirmed that the Pt atoms were stabilized by bonding with oxo ligands, forming a PtO4 moiety embedded in γ-Al2O3 lattices with coordination geometries resembling those of mononuclear homogeneous catalysts. Density functional theory calculations revealed that the unexpected catalytic performance could be attributed to the partially positively charged and atomically dispersed Pt atoms in the Pt1/γ-Al2O3 catalyst, which arose from metal–support interaction through oxo ligands, resulting in an elevated d-orbital energy and an upshift in the d-band center away from the Fermi level. This electronic effect facilitated the easier dissociation of phenylethyl and promoted its coupling with the dimethylphenylsilyl group on the catalyst surface, ultimately leading to the desired product.

A valence-state heterojunction Mn 3 O 4 /γ-MnOOH was synthesized for norfloxacin (NOR) degradation under concurrent visible light and magnetic field. The charge carriers could transfer between the valence state components facilely, inhibiting recombination of photo-induced electron-holes significantly. Efficient NOR degradation by Mn 3 O 4 /γ-MnOOH was realized at 98.8% (rate constant of 0.0720 min −1 ) within 60 min under magnetic field assisted visible light. In neutral media, the positively charged NOR and negatively charged Mn 3 O 4 /γ-MnOOH would arrange in an oriented manner in the presence of magnetic field, providing more active sites for NOR during photocatalysis . Moreover, the opposite Lorentz forces contributed to the attractive interactions between NOR and Mn 3 O 4 /γ-MnOOH, accelerating NOR degradation with lower active energy. Quenching experiment showed that ∙O 2 − and h + played dominant roles in NOR degradation. Attractively, this study shed new lights on an innovative strategy of magnetic field assisted photocatalysis for refractory contaminants remediation from water.

Here we exquisitely fabricated Cu/ZrO 2 -dp catalysts with plentiful Cu-ZrO 2 interfaces by depositing amorphous ZrO 2 onto Cu nanoparticles for the hydrogenation of levulinic acid (LA) to γ-valerolactone (GVL). With the created plentiful Cu-ZrO 2 interfaces, the optimal catalyst 3Cu/ZrO 2 -dp exhibited exceptional catalytic performance under mild reaction conditions, and achieved the highest GVL mass productivity of 266.0 mmol GVL·h −1 ·g −1 Cu, which was 12.5 and 2.3 times of Cu/ZrO 2 catalysts with equivalent Cu loadings prepared by traditional impregnation (3Cu/ZrO 2 -im) or co-precipitation (3Cu/ZrO 2 -cp). As far as we know, this GVL mass productivity stood at the highest level compared with those obtained using non-noble metal catalysts under similar reaction conditions. By systematic investigation with multiple characterizations, density functional theory (DFT) calculations, and kinetic studies, it was found that interfacial active centers were created at Cu-ZrO 2 interfaces, which contained oxygen vacancies (O v ), negatively charged Cu δ− and partially reduced Zr 3+ . The O v favored the adsorption and activation of LA via its ketone group, while negatively charged Cu δ− was able to enhance heterolysis of H 2 , which resulted in the formation of H + -Cu δ− and Zr 3+ -H − active species via hydrogen spillover. Also, plentiful acid sites, which derived from coordinatively unsaturated and defective Zr species, generated at Cu-ZrO 2 interfaces. With the cooperation of interfacial active centers (Cu δ− -O v -Zr 3+ ) and acid sites, the fabricated 3Cu/ZrO 2 -dp with plentiful Cu-ZrO 2 interfaces achieved excellent catalytic performance for the hydrogenation of LA to GVL. Hence, the synergistic catalysis of Cu-ZrO 2 interfaces provided an effective strategy for designing catalysts with a satisfactory performance for the hydrogenation of LA, which also can be expanded to other hydrodeoxygenation reactions.
