The role of emulsifier morphology in shaping the rheology of food-grade Pickering and non-Pickering high internal phase emulsions (HIPPEs and HIPnPEs) remains difficult to isolate, as previous comparisons often involved simultaneous variations in emulsifier identity and morphology. Here, we exploit the pH-induced coil-to-aggregate transition of tannic acid–chitosan complexes (TACS) to prepare component-consistent molecular and particulate emulsifiers, enabling a morphology-focused comparison. Small-amplitude oscillatory shear (SAOS) tests show that TACS particle packing provides HIPPEs with an additional elastic contribution, resulting in higher storage moduli than their HIPnPE counterparts and marked positive deviations from the Princen–Kiss prediction. Under large-amplitude oscillatory shear (LAOS), TACS-stabilized HIPPEs exhibit Type I network breakdown, whereas the HIPnPE counterparts display Type III behavior with more pronounced strain hardening and shear thickening. These contrasting responses suggest that TACS-stabilized HIPPEs may be suited to firm, rest-stable foods, whereas the HIPnPE counterparts may benefit processing that requires structural recovery. By isolating emulsifier morphology as the primary variable, this work identifies its contribution to rheology of high internal phase emulsions and provides a model strategy for morphology-directed rheological design.

This study examines the evolving tonal relationship between Disney’s classic 2D animated features and their ‘live-action’ remakes, challenging the binary discourse that assigns slapstick humour to 2D animation and seriousness to live-action remakes in popular commentary. While 2D animations prominently employ slapstick with visual gags and physical exaggeration, they also embed serious narrative and themes of identity, morality, and responsibility, complicating their categorization as pure comedies. Conversely, while live-action remakes tone down the slapstick by enhancing tragedy, horror, and socio-political subtext and prioritizing solemnity, they retain traces of their predecessors’ humour through situational comedic reworking. The study critiques popular critical narratives that absolutize these tonal transitions, instead arguing for a dynamic interaction of humour and seriousness to enhance narrative depth and audience engagement. Ultimately, the findings position tonal hybridity—with humour as an entry point and seriousness as a reflective anchor—at the heart of Disney’s transmedia remaking aesthetics, enabling the studio to reconcile tradition and modernity while maintaining artistic relevance and market dominance.

Plasma amplification laser-induced breakdown spectroscopy (Plasma amplification LIBS) has shown great potential in N elements in water due to high sensitivity, precision, and accuracy. To further reduce interferes of the atmospheric nitrogen, the effect of laser wavelength on the quantitative determination of nitrogen in water was investigated. With short laser wavelength, stronger spectral line intensity, lower interference from atmospheric nitrogen, and superior analytical performance were obtained. The linear coefficient of determination (R²) of the calibration curve improved from 0.2147 to 0.9732, the limit of detection (LOD) was reduced from 18.98 ppm to 3.41 ppm, and the spectral stability, expressed as average relative standard deviation (RSDAV), was reduced from 10.49% to 5.45%. Moreover, the average relative error (REAV) and the root mean square error of cross-validation (RMSECV) for the predicted concentrations were improved by approximately 56.82% and 71.79%, respectively. These results demonstrate that the 532 nm wavelength in plasma amplification LIBS can significantly enhance both the detection sensitivity and the accuracy of quantitative analysis for nitrogen in water.

In conventional photoelectrochemical (PEC) water-splitting
systems,
the high recombination rate of photogenerated charge carriers and
sluggish interfacial charge transfer kinetics serve as the core bottlenecks
restricting energy conversion efficiency. In this study, a sulfur-vacancy-engineered
Vs-ZnS/In 2 S 3 heterojunction was constructed
to demonstrate the “electron relay” function of sulfur
vacancies within a Type-II heterojunction. Specifically, sulfur vacancies
create a localized shallow trap level below the conduction band of
In 2 S 3 , amplifying the potential driving force
for interfacial electron transfer. Concurrently, these defect states
effectively capture photogenerated electrons transitioning across
the interface and serve as highly active sites directly participating
in surface reactions, thereby significantly suppressing both the bulk
and surface recombination of charge carriers. Benefiting from this
synergistic mechanism, the as-prepared Vs-ZnS/In 2 S 3 photoelectrode exhibits exceptional PEC performance, achieving
a maximum photocurrent density of 1.26 mA·cm –2 and an applied bias photon-to-current efficiency of approximately
0.26%. This is substantially superior to pristine ZnS and conventional
ZnS/In 2 S 3 electrodes. Kinetic and separation
efficiency characterizations indicate that the bulk and surface charge
separation efficiencies are drastically improved to 68.4% and 38.1%,
respectively. This exceptional performance stems from the synergistic
interplay between the heterojunction and the sulfur vacancies: the
localized electronic structure modulated by defect states facilitates
the directional transfer of interfacial electrons and accelerates
the hydrogen evolution reaction kinetics. This work provides a novel
design paradigm for regulating charge transport pathways within heterojunctions
via defect engineering to realize highly efficient energy conversion.

The photocatalytic activity of TiO2 based photocatalysts can be improved by structural modification and elemental doping. In this study, through rational design, one type of carbon and nitrogen co-doped TiO2 (C, N-TiO2) photocatalyst with mesoporous structure was synthesized with improved photocatalytic activity in degrading 4-nitrophenol under simulated sunlight irradiation. The photocatalytic degradation efficiency of the C, N-TiO2 was much higher than the anatase TiO2 (A-TiO2) based on absorbance and HPLC analyses. Moreover, using zebrafish embryos, we showed that the intermediate degradation compounds generated by photocatalytic degradation of 4-nitrophenol had higher toxicity than the parent compound. A repeated degradation process was necessary to render complete degradation and non-toxicity to the zebrafish embryos. Our results demonstrated the importance of evaluating the photocatalytic degradation efficiency in conjunction with the toxicity assessment of the degradation compounds.

Ions are often introduced into graphene oxide (GO) membranes during their preparation and application, which may lead to changes in their properties. In this study, GO membranes regulated by ions were prepared by incorporating alkali and alkaline earth metals. We found that the introduction of different ions led to opposite changes in the electrical properties of the reduced GO (RGO) membranes. The introduction of alkali metal ions improves their conductivity, whereas the introduction of alkaline earth metal ions results in a decrease in their conductivity. Furthermore, we found that the introduction of ions resulted in significantly different changes in the luminescence spectra, which could be used to detect alkali and alkaline earth metal ions. In addition, the introduction of alkali metal and alkaline earth metal ions resulted in significantly different changes in the luminescence spectra and microwave reduction effect of the RGO membranes. The introduction of alkaline earth metal ions was more helpful for the removal of oxygen-containing groups and the restoration of the graphene lattice structure when exposed to microwave irradiation. These results suggest that the properties of GO membranes can be regulated by regulating the introduction of ions, and these findings have potentially important applications in the preparation and application of GO membranes and ion detection.

The global phenomenon of eating poisonous mushrooms by mistake occurs every year. Untargeted lipidomics analysis combined with chemometrics was used to identify mushroom varieties. Two kinds of mushrooms with similar appearance, namely, Pleurotus cornucopiae (P. cornucopiae) and Omphalotus japonicus (O. japonicus) were selected as models, where O. japonicus was a poisonous mushroom and P. cornucopiae was an edible mushroom. First, the lipid extraction efficiency of eight solvents was compared. The methyl tert-butyl ether/methanol (2:1, v/v) had higher lipid extraction efficiency of extracting mushroom lipids than other solvents, in terms of the lipid coverage, response intensity, and solvent safety. Afterward, the comprehensive lipidomics analysis of the two mushrooms was conducted. A total of 21 lipid classes and 267 molecular species were identified in O. japonicus, whereas 22 lipid classes and 266 molecular species in P. cornucopiae. The principal component analysis demonstrated that 37 characteristic metabolites, including TAG 18:1_18:2_18:0;1O, TAG 18:1_18:1_18:2, TAG 16:2_18:2_18:2, etc., could be used to distinguish the two mushrooms. These differential lipids were able to identify P. cornucopiae blended with 5% (w/w) O. japonicus. This study explored a novel method for identifying poisonous mushrooms from edible mushrooms and provided a reference for food safety of consumers.

The concept of combining external medical stimuli with internal functional biomaterials to serve cancer-oriented treatments is emergingly developed. Optical and acoustical activations have shown special promises as non-invasive regulation modalities in cancer treatment and intervention. It is always challenging to leverage their contributions between optical and acoustical stimuli and find the appropriate biomaterials to optimally match them. Herein, a type of hybrid nanomicelles (ICG@PEP@HA) containing ICG as photo/sonosensitizers, an amphiphilic peptide for membrane penetration and hyaluronic acid for cluster determinant 44 (CD44) targeting were fabricated. Triggered by external stimuli of laser and US irradiations, their photo/sonothermal performances, in vitro reactive oxygen species (ROS) production capabilities and tumor-targeting efficiency have been systematically evaluated. It was interestingly found that the external stimulus of laser induced more quantity of ROS which resulted in a significant cell apoptosis and tumor growth inhibition in the presence of ICG@PEP@HA. The individual analysis and corresponding rationales have been investigated. In the meanwhile, these hybrid nanomicelles were administered into the MDA-MB-231 tumor-bearing nude mice for PDT and SDT therapies and their biocompatibility assessment, and a PDT prevailing efficacy and reliable bio-safety have been evidenced based on the hematological analysis and histochemical stainings. In summary, this study has validated a novel pathway to utilize these hybrid nanomicelles for laser/US-triggered localized tumor treatments, and the treatment efficiency may be leveraged by different external stimuli sources. It is also expected to give birth to full accessibility to clinical translations for human cancer treatments by means of as-reported laser/US-nanomicelles combination strategy.

Thermo-enhanced photocatalysis has been reported as a potential strategy for improving the activity, whereas the relationship between thermal energy and the localized surface plasmon resonance (LSPR) effect of noble metal nanoparticles has been rarely investigated. Herein, photocatalytic selective aerobic oxidation of amines to imines is investigated under visible light irradiation over heterostructured TiO2(B)/anatase and Au/TiO2 nanobelts at specific temperatures (20–60 °C). The surface amine substrate complexed on TiO2 could broaden the visible-light absorption region via the ligand-to-metal charge transfer (LMCT) effect. Interestingly, the pristine TiO2 achieves the best photocatalytic performance (>99% benzylamine conversion and >99% N-benzylidenebenzylamine selectivity) at 60 °C after 12 h irradiation while the Au nanoparticles (NPs) are observed to improve the activity of TiO2 only in a low temperature range (<40 °C). Moreover, excessive Au NPs loaded on TiO2 could inhibit the amine conversion and reduce the imine selectivity in the whole temperature range of 20–60 °C, which is attributed to the decreased oxygen vacancies and poor amine adsorption ability on the surface of Au/TiO2. A plausible explanation is finally proposed that the substrate–TiO2 complex, instead of plasmonic Au NPs, plays a vital role in achieving good amine conversion and imine selectivity.

Transition-metal oxide-mediated peroxide activation systems have been demonstrated to initiate selective degradation of pollutants, while the underlying mechanism remains unclear and sometimes controversial. In this study, we systematically explored the reactive species/pathways for pollutant degradation in the Mn oxide octahedron molecular sieve (OMS-2)-triggered peracetic acid (PAA) activation system. By separating PAA activation and pollutant oxidation processes using a sequential activation/oxidation system or galvanic oxidation system, we confirm that the OMS-2/PAA system follows the reactive metal species mechanism, where surface reactive Mn(IV) species, rather than Mn–PAA complexes, are primarily responsible for the nonradical oxidation of bisphenol A. OMS-2 shows varied peroxide-activating activities (i.e., catalase-like and peroxidase-like activities) toward different peroxides (i.e., H2O2, PAA, and persulfates), depending on the reactivity of surface reactive Mn(IV) species with those peroxides. In addition, the long-lived surface reactive Mn(IV) species exhibit excellent resistance to fluctuations in solution pH and interference from coexisting anions and natural organic matter. This study offers novel insights into the nonradical mechanism involved in Mn oxide-mediated peroxide activation processes.

Hydrolysis catalyzed by metal oxides is an effective approach for removing carbonyl sulfide (COS) from blast furnace gas, but constructing highly active catalytic sites that function efficiently under low–temperature conditions remains a fundamental challenge. In this work, perovskite–type niobate catalysts (KNbO 3 , NaNbO 3 , and LiNbO 3 ) are synthesized via a sol–gel method and subsequently modified under a strongly reducing NH 3 atmosphere at elevated temperatures to simultaneously generate oxygen vacancies and nitrogen dopants (both substitutional and interstitial), thereby significantly enhancing their catalytic performance and H 2 S selectivity for COS hydrolysis. Among them, NH 3– treated N–KNbO 3 achieves 100% COS conversion and 100% H 2 S selectivity at 100 °C. Comprehensive physicochemical characterizations and density functional theory (DFT) calculations indicate that NH 3 treatment achieves a “four–in–one” effect: oxygen vacancy engineering, nitrogen doping, morphology engineering, and modulation of surface active sites. This study systematically elucidates the structure–activity relationship underlying the synergistic interplay between nitrogen doping and oxygen vacancies in KNbO 3 , demonstrates the cooperative promotional role of oxygen vacancies and interstitial nitrogen during hydrolysis, and underscores the critical importance of surface reactive oxygen species and weakly basic sites. These findings provide both a theoretical foundation and practical design strategies for developing high–performance catalysts for low–temperature COS hydrolysis.

Hard carbon (HC) is a promising anode for sodium-ion batteries (SIBs) due to its low cost and favorable electrochemical properties. However, its rate capability remains limited by sluggish ion transport and structural constraints. Herein, solid and hollow hard‑carbon nanofibers (HC-Fs and HC-HFs) are fabricated via uniaxial and coaxial electrospinning, respectively, to elucidate the role of architecture in sodium-storage behavior. The hollow structure endows HC-HFs with enlarged surface area, hierarchical porosity, and shortened ion/electron transport pathways, enabling enhanced reaction kinetics. Operando and in situ characterizations, including X-ray diffraction, Raman spectroscopy, and electrochemical impedance spectroscopy coupled with distribution of relaxation time (DRT) analysis, reveal that the hollow architecture facilitates Na + adsorption, intercalation, and diffusion while promoting the formation of a stable and conductive solid-electrolyte interphase. As a result, HC-HFs exhibit reduced interfacial and diffusion resistances compared with HC-Fs. Benefiting from a three-dimensional interconnected and binder-free framework, HC-HFs deliver a high reversible capacity of 206.7 mAh g −1 at 2120 mA g −1 , demonstrating excellent high-rate performance. This work provides fundamental insights into structure-kinetics relationships and offers an effective strategy for designing advanced carbon anodes for fast-charging SIBs.
