AbstractA bifunctional electrocatalyst is developed, exhibiting high catalytic activity and reversibility for the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) through a regulative Fe d‐orbital engineering strategy. In this strategy, iron phthalocyanine organic molecule (FeOM) crystals are axially coordinated onto multilayer Mo2CTx MXene (FeOM‐Mo2CTx), adopting a lying‐down conformation. This hybridization fosters unique electronic guest–host interactions, with FeOM donating charge to Mo2CTx via Fe−O bonding, leading to symmetry breaking in electronic distribution and modified delocalization of Fe‐3d charge, accompanied by a Fe(II) spin‐state transition. These transformations enhance the adsorption and desorption toward oxygenated intermediates, optimizing the *OOH−*O transition to boost the reversibility of ORR and OER kinetics. The FeOM‐Mo2CTx exhibits a favorable ORR half‐wave potential of 0.961 V and a minimal OER overpotential of 349 mV at 10 mA cm−2 in 1.0 m KOH. The assembled aqueous zinc‐air battery (ZAB) achieves a peak power density of 155.3 mW cm−2 and exceptional charge–discharge durability over 1500 h, outperforming a conventional (Pt/C + RuO2) system. Overall, the findings underscore the significance of electronic structural engineering of FeOM with Mo2CTx, paving the way for innovative air cathodes in the development of rechargeable ZABs with enhanced performance and cost‐effectiveness.

AbstractThe photosynthesis of hydrogen peroxide (H2O2) via the selective two‐electron oxygen reduction reaction (ORR) is emerging as a promising method for producing this important chemical. However, the reliance on sacrificial agents has limited the practical application of many photocatalysts. Herein, nitrogen‐doped graphene quantum dots (NGQDs) are loaded onto the surface of MnxCd1‐xS solid solution nanowires to enable overall H2O2 photosynthesis in pure water under an air atmosphere. The optimized Mn0.2Cd0.8S/NGQDs (M0.2NG5) composite achieves a high yield of 6885 µmol g−1 h−1, which is 10.4 times and 4.5 times higher than that of CdS (661 µmol g−1 h−1) and Mn0.2Cd0.8S (1522 µmol g−1 h−1), respectively. The NGQDs act as co‐catalysts, enhancing the conductivity of the system. The strong electronegativity and polarity of the incorporated nitrogen and functional groups on the NGQDs edges enhance the ability of carbon atoms to activate O2 into ·O2−. The mechanism of H2O2 photosynthesis is investigated using in situ Fourier transform infrared spectroscopy, intermediate trapping experiments, and theoretical calculations. This work offers new insights into the design of non‐noble metal co‐catalyst‐modified photocatalysts for sacrificial‐agent‐free H2O2 production.

AbstractMyocarditis, a leading cause of sudden cardiac death and heart transplantation, poses significant treatment challenges. The study of clinical samples from myocarditis patients reveals a correlation between the pathogenesis of myocarditis and cardiomyocyte mitochondrial DNA (mtDNA). During inflammation, the concentration of mtDNA in cardiomyocytes increases. Hence, it is hypothesized that the combined clearance of mtDNA and its downstream STING pathway can treat myocarditis. However, clearing mtDNA is problematic. An innovative mtDNA scavenger is introduced, Nanosweeper (NS), which utilizes its nanostructure to facilitate the transport of NS‐mtDNA co‐assemblies for degradation, achieving mtDNA clearance. The fluorescent mtDNA probe on NS, bound to functional peptides, enhances the stability of NS. NS also exhibits robust stability in human plasma with a half‐life of up to 10 hours. In a murine myocarditis model, NS serves as a drug delivery vehicle, targeting the delivery of the STING pathway inhibitor C‐176 to the myocardium. This approach synergistically modulates the cGAS‐STING axis with NS, effectively attenuating myocarditis‐ associated inflammatory cascade. This evaluation of NS in porcine models corroborated its superior biosafety profile and cardiac targeting capability. This strategic approach of targeted mtDNA clearance couple with STING pathway inhibition, significantly augments therapeutic efficacy against myocarditis, outperforming the conventional drug C‐176, indicating its clinical potential.

AbstractAntigen‐presenting cells (APCs) process tumor vaccines and present tumor antigens as the first signals to T cells to activate anti‐tumor immunity, which process requires the assistance of co‐stimulatory second signals on APCs. The immune checkpoint programmed death ligand 1 (PD‐L1) not only mediates the immune escape of tumor cells but also acts as a co‐inhibitory second signal on APCs. The serious dysfunction of second signals due to the high expression of PD‐L1 on APCs in the tumor body results in the inefficiency of tumor vaccines. To overcome this challenge, a previously established Plug‐and‐Display tumor vaccine platform based on bacterial outer membrane vesicles (OMVs) is developed into an “Antigen Presentation Signal Enhancer” (APSE) by surface‐modifying PD‐L1 antibodies (αPD‐L1). While delivering tumor antigens, APSE can activate the expression of co‐stimulatory second signals in APCs due to the high immunogenicity of OMVs. More importantly, the surface‐modified αPD‐L1 binds to the co‐inhibitory signals PD‐L1, potentially restoring CD80 function and ensuring efficient co‐stimulatory second signals and activation of anti‐tumor immunity. The results reveal the importance of PD‐L1 blockage in the initiation process of anti‐tumor immunity, and the second signal modulation capability of APSE can expand the application potential of cancer vaccines to less immunogenic malignancies.
Electric Field‐Induced Nonreciprocal Directional Dichroism in a Time‐Reversal‐Odd Antiferromagnet
Authors: Hayashida Takeshi , Matsumoto Koei , Kimura Tsuyoshi 
Published: January 2025

AbstractAntiferromagnets with broken time‐reversal () symmetry (‐odd antiferromagnets) have gained extensive attention, mainly due to their ferromagnet‐like behavior despite the absence of net magnetization. However, certain types of ‐odd antiferromagnets remain inaccessible by the typical ferromagnet‐like phenomena (e.g., anomalous Hall effect). One such system is characterized by a ‐odd scalar quantity, the magnetic toroidal monopole. To access the broken symmetry in such a system, a unique nonreciprocal optical phenomenon, electric field‐induced nonreciprocal directional dichroism (E‐induced NDD), is employed. Signals of E‐induced NDD are successfully detected in a ‐odd antiferromagnet, Co₂SiO₄, whose magnetic structure is characterized by the magnetic toroidal monopole. Furthermore, by spatially resolving the E‐induced NDD, spatial distributions of a pair of domain states related to one another by the operation are visualized. The domain imaging revealed the inversion of the domain pattern by applying a magnetic field, which is explained by trilinear coupling attributed to the piezomagnetic effect. The observation of E‐induced NDD highlights unique functionalities of ‐odd antiferromagnets.

Published: January 2025

AbstractReplicating the structural and functional features of native myocardium, particularly its high‐density cellular alignment and efficient electrical connectivity, is essential for engineering functional cardiac tissues. Here, novel electrohydrodynamically printed InterPore microfibrous lattices with anisotropic architectures are introduced to promote high‐density cellular alignment and enhanced tissue interconnectivity. The interconnected pores in the microfibrous lattice enable dynamic, cell‐mediated remodeling of fibrous hydrogels, resulting in continuous, mechanically stable tissue bundles. Compared to lattices with isolated pores, the engineered aligned cardiac tissues from neonatal rat cardiomyocytes exhibit improved electrophysiological properties and synchronous contractions. Using a multiseeding strategy, an equivalent cell seeding density of 8 × 107 cells mL−1, facilitating the formation of multicellular, vascularized cardiac structures with maintained tissue viability and integrity, is achieved. As a demonstration, human‐induced pluripotent stem cell‐derived cardiac tissues are engineered with progressive maturation and functional integration over time. These findings underscore the potential of InterPore microfibrous lattices for applications in cardiac tissue engineering, drug discovery, and therapeutic development.

AbstractHigh‐voltage phase changes limit the capacity and cycle stability of P2‐type sodium‐layered transition metal oxides. In this study, Cu, Zn, and Mg ions are successfully co‐doped into Na0.67Ni0.33Mn0.67O2 to restrain the phase transition and increase Na+ diffusion with enhanced structural stability. In situ and ex situ evaluations elucidate the structural and charge compensation during high‐voltage operation. Remarkably, the resultant Na0.76Ni0.23Cu0.07Zn0.03Mn0.62Mg0.05O2 (NNCZMMO) cathode exhibits superior rate capability (135 and 94.0 mA h g−1 at 0.1C and 5C), prolonged‐cycling stability (85.4% capacity retention over 1000 cycles at 5C) and excellent air/water stability over 40 days. According to density functional theory (DFT), scanning transmisson electron microscopy (STEM), and other assessments, Cu at 2a sites strengthens the metal layer, whereas Zn/Mg on Na sites creates a “dual‐pillar” effect to avoid cracks and O2 phase formation during desodiation. Impressively, NNCZMMO//hard carbon (HC) full‐cell achieved an exceptional average voltage of 3.58 V and an outstanding energy density of 284.7 Wh kg−1 at 60.8 W kg−1 and 104.23 Wh kg−1 at 2439.5 W kg−1. This innovative approach enables the rapid fabrication of high‐energy‐density cathodes for grid‐scale energy‐storage usages.

Published: January 2025

AbstractFluorescent molecules are vital parts of modern chemistry and find widespread use in our daily lives, being potent tools for quantitatively and qualitatively determining analytes in many habitats, including living systems. Their exceptional properties allow us to visualize and understand complex biological processes, even beyond intracellular levels, advancing our knowledge of life; they also play a focal role in materials science and the environment. All these facts highlight these compounds′ impact in all sciences despite several restricted uses since many dyes have poor synthetic viability and biocompatibility with limited optical and electronic properties. These flaws could be solved by conjugating a representative fluorophore with an N‐heteroaromatic moiety, which has proven helpful in this target. Thus, this review aims to analyze advances from the years 2019 to 2023 in syntheses and photophysical properties of N‐heteroaromatic compounds conjugated with (i) triphenylamine (TPA), (ii) coumarin (CM), (iii) boron complexes (BC), or (iv) aromatic hydrocarbons (AHs).

Published: January 2025

AbstractSmart luminescent materials have drawn a significant attention owing to their unique optical properties and versatility in sensor applications. These materials, encompassing a broad spectrum of organic, inorganic, and hybrid systems including quantum dots, organic dyes, and metal‐organic frameworks (MOFs), offer tunable emission characteristics that can be engineered at the molecular or nanoscale level to respond to specific stimuli, such as temperature, pH, and chemical presence. This adaptability makes them crucial in developing advanced sensor technologies for environmental monitoring, biomedical diagnostics, and industrial applications with the help of the luminescence mechanisms, such as fluorescence, phosphorescence, and upconversion. Recent advancements have been driven by the integration of nanotechnology, which enhances the sensitivity and selectivity of luminescent materials in sensor platforms. The development of photoluminescent and electrochemiluminescent sensors, for instance, has enabled real‐time detection and quantification of target analytes with high accuracy. Additionally, the incorporation of these materials into portable, user‐friendly devices, such as smartphone‐based sensors, broadens their applicability and accessibility. Despite their potential, challenges remain in optimizing the stability, efficiency, and biocompatibility of these materials under different conditions. This review provides a comprehensive overview of the fundamental principles of smart luminescent materials, discusses recent innovations in their use for sensor applications, and explores future directions aimed at overcoming current limitations and expanding their capabilities in meeting the growing demand for rapid and cost‐effective sensing solutions.
A new approach for solving the multidimensional control optimization problems with first‐order partial differential equations constraints
Authors: Preeti  , Jayswal Anurag , Antczak Tadeusz 
Published: January 2025

AbstractThe purpose of this paper is to provide the linearization technique to solve the multidimensional control optimization problem (MCOP) involving first‐order partial differential equation (PDEs) constraints. Firstly, we use the modified objective function approach for simplifying the aforesaid extremum problem (MCOP) and show that the solution sets of the original control optimization problem and its modified control optimization problem (MCOP)
are equivalent under convexity assumptions. Further, we use the absolute value exact penalty function method to transform (MCOP)
into a penalized control problem (MCOP)
. Then, we establish the equivalence between a minimizer of the modified penalized optimization problem (MCOP)
and a saddle point of the Lagrangian defined for the modified optimization problem (MCOP)
under appropriate convexity hypotheses. Moreover, the results established in the paper are illustrated by some examples of MCOPs involving first‐order PDEs constraints.
The education experiences of young people experiencing child criminal and sexual exploitation
Authors: Lloyd Jenny 
Published: January 2025

AbstractSchool exclusion forms part of the processes that can increase young people's risk of offending and involvement in exploitation and harm. However, little is known about the education experiences of young people impacted by harm, such as child sexual and criminal exploitation. This paper presents findings from a survey with 17 children's and families' social care departments in England and Wales to understand the education experiences of children open to social care for extra‐familial harm. The research was undertaken at a time of significant pressure on schools and teachers to improve academic performance. The findings evidence that 45% of young people were in mainstream settings, 85% of young people had experienced some form of exclusion and this differed across gender, disability and ethnicity. Finally, the reasons for exclusion were strongly associated with young people's experiences of exploitation and harm. Two theories of containment are used to understand school exclusion: psychosocial and geopolitical. I argue that exclusionary school practices spatially contain the perceived ‘threat’ young people impacted by extra‐familial harm pose to wider school populations, to emotionally contain professional anxieties about exploitation and violence, in the absence of appropriate educational and safeguarding system responses.

AbstractCatalytic biomass gasification is a promising thermochemical conversion pathway for converting palm oil empty fruit bunch (EFB) into hydrogen (H2) as future energy needed to support the global net‐zero emission goal in 2050. This study developed a limonite catalyst, a byproduct of nickel mining, to enhance hydrogen‐rich bio‐syngas production from EFB gasification. The findings demonstrate that limonite has successfully catalyzed the biomass gasification process with an increase in bio‐syngas production by 27–30 % volume. At an operating temperature of 700 °C, the use of limonite catalyst and steam as gasifying agent produced 24 L of bio‐syngas with H2/CO ratio 15.84, and H2 accounting for the largest share at 63.45 % volume.

Published: January 2025

AbstractThe dynamic behavior of a toluene/NaOH solution system was studied in a batch stirred tank. Characterization by step response experiments showed that the drop size response to stirrer speed steps behaves as a first‐order system, whereas the stirrer speed responds as a second‐order system. The respective time constants differed by at least one order of magnitude, suggesting effective control of the drop size is feasible by adjusting the stirrer speed. Based on experimental data, simple, linear system models were derived for the mean drop diameter and the interfacial area using the stirrer speed as input variable. Validation experiments showed good model qualities of about 70 % and the design of test trajectories proved the model's usability in an open‐loop control.
