Tailored Broad‐Spectrum Emission in Hybrid Aggregation Induced Emission (AIE)‐MOFs: Boosting White Light Efficiency in Electrospun Janus Microfibers
Authors: Kachwal Vishal , Mollick Samraj , Tan Jin‐Chong 
Published: October 2023

AbstractAdvances in energy‐efficient lighting and display technologies demand innovative materials with tailored broad‐spectrum emission properties. Hybrid aggregation‐induced emission metal‐organic frameworks (AIE‐MOFs) offer a promising avenue, combining unique characteristics of organic and inorganic components to yield enhanced luminescence efficiency and robust material stability. The study introduces a spectrum of D (donor)‐A (acceptor) type AIE‐active ligands into MOFs, enabling tunable emission across the visible spectrum, thus underscoring the versatility of these hybridized MOF materials. The emission properties of AIE‐MOFs are further harnessed by integrating them into polymer matrices, resulting in high‐performance electrospun fibers with tunable emission. A significant achievement involves the fabrication of Janus‐type white light‐emitting AIE‐MOF fiber composites via side‐by‐side electrospinning, accomplishing a high quantum yield of 58%, which doubled the performance of homogeneous fibers. Complementing the experimental findings, micro‐Raman and nano‐Fourier transform infrared spectroscopy are employed as local spectroscopic probes, affording a deeper understanding of the material properties and the mechanisms contributing to enhance light emission. In the understanding, this study presents an unconventional implementation of hybrid AIE‐MOFs in Janus‐type structures for white light emission. It significantly improves the efficiency of white light sources in optoelectronics, charting a promising direction for future research in the emergent AIE‐MOF field.

AbstractRational design of efficient single‐atom catalysts is a potential avenue to mitigate the sluggish oxygen evolution reaction (OER) kinetics. Adopting appropriate matrixes to stabilize the single‐atom active centers with the optimized geometric and electronic structure plays an essential role in enhancing catalytic activities. Herein, massive isolated Ce atoms are successfully anchored on monolayer nickel‐vanadium layered double hydroxide support (Ce SAs/m‐NiV LDH) via the vanadium defects trapping strategy, resulting in stabilized Ce single‐atom with the maximum loading of 8.07 wt.%. Benefitting from the strong synergetic electronic interaction between Ce single atoms and monolayer NiV LDH matrix, thus‐prepared catalyst possesses favorable OER (209 mV @ 10 mA cm−2) and water electrolysis performance (1.47 V @ 10 mA cm−2), surpassing other catalysts and even the commercial RuO2 catalyst. Density functional theory (DFT) calculations in combination with in situ electrochemical impedance spectroscopy analysis reveal that the immobilization of monatomic Ce can effectively narrow the band gap and strengthen the density states near the Fermi level as well as more easily adsorb the surficial OH–, leading to a lower charge transfer barrier and faster water splitting kinetics.

AbstractEffectively integrating infection control and osteogenesis to promote infected bone repair is challenging. Herein, injective programmable proanthocyanidin (PC)‐coordinated zinc‐based composite hydrogels (ipPZCHs) are developed by compositing antimicrobial and antioxidant PC‐coordinated zinc oxide (ZnO) microspheres with thioether‐grafted sodium alginate (TSA), followed by calcium chloride (CaCl2) crosslinking. Responsive to the high endogenous reactive oxygen species (ROS) microenvironment in infected bone defects, the hydrophilicity of TSA can be significantly improved, to trigger the disintegration of ipPZCHs and the fast release of PC‐coordinated ZnOs. This together with the easily dissociable PC‐Zn2+ coordination induced fast release of antimicrobial zinc (Zn2+) with/without silver (Ag+) ions from PC‐coordinated ZnOs (for Zn2+, > 100 times that of pure ZnO) guarantees the strong antimicrobial activity of ipPZCHs. The exogenous ROS generated by ZnO and silver nanoparticles during the antimicrobial process further speeds up the disintegration of ipPZCHs, augmenting the antimicrobial efficacy. At the same time, ROS‐responsive degradation/disintegration of ipPZCHs vacates space for bone ingrowth. The concurrently released strong antioxidant PC scavenges excess ROS thus enhances the immunomodulatory (in promoting the anti‐inflammatory phenotype (M2) polarization of macrophages) and osteoinductive properties of Zn2+, thus the infected bone repair is effectively promoted via the aforementioned programmable and self‐adaptive processes.

AbstractIn implantable bioelectronics, which aim for semipermanent use of devices, biosafe energy sources and packaging materials to protect devices are essential elements. However, research so far has been conducted in a direction where they cannot coexist. Here, the development of capacitance‐matched triboelectric implants driven is reported by ultrasound under 500 mW cm−2 safe intensity and realize a battery‐free, miniatured, and wireless neurostimulator with full titanium (Ti) packaging. The triboelectric implant with high dielectric composite, which has ultralow output impedance, can efficiently deliver sufficient power to generate the stimulation pulse without an energy‐storing battery, despite ultrasound attenuation due to the Ti, and has the highest energy transmission efficiency among those reported so far. In vivo study using a rat model demonstrated that the proposed device system is an effective solution for relieving urinary symptoms. These achievements provide a significant step toward permanently implantable devices for controlling human organs and treating various diseases.

AbstractFrequency upconversion photodetection by two‐dimensional (2D) materials with nonlinear optical response is an appealing technique for applications such as extending photodetection wavelength range, autocorrelation measurement, and high‐efficiency single photon detection. However, the frequency upconversion efficiency in 2D materials is limited due to the low efficiency of nonlinear optical processes and atomic light‐matter interaction length. Here, the efficient frequency upconversion photodetection is realized by van der Waals (vdW) integration of a few‐layer InSe with a silicon photonic crystal cavity (Si‐PPC). With the large second‐order nonlinearity of InSe and enhanced light‐matter interaction by Si‐PCC, continuous wave (CW) pumped second harmonic generation (SHG) is demonstrated with pump power down to 100 µW. Further, InSe and Si absorb the SHG photons and generate photocarriers which are separated and collected by the n‐InSe/p‐Si heterojunction. A frequency upconversion photoresponsivity of 16 µA W−1 with a CW laser at 1467 nm is obtained. More efficient SHG with pulsed laser improves the responsivity to 3.9 mA W−1 with quadratic power dependence, which is record‐high among the frequency upconversion photodetectors based on 2D materials. This work opens up opportunities for a high‐efficiency 2D material nonlinear photodetector integrated on photonic integrated circuits.

AbstractHere we report a light‐induced FeCl3‐catalyzed approach for benzyl C−H chlorination with remarkable regioselectivity, which enables alkylbenzenes to be converted into versatile benzyl chlorides under mild conditions using trifluoromethanesulfonyl chloride (TfCl) as the chlorine source. DFT calculations show that the dynamics preference of benzylic α−C−H chlorination is more pronounced by employing TfCl.

AbstractEpstein‐Barr virus (EBV) is associated with various malignancies and infects >90% of the global population. EBV latent proteins are expressed in numerous EBV‐associated cancers and contribute to carcinogenesis, making them critical therapeutic targets for these cancers. Thus, this study aims to develop mRNA‐based therapeutic vaccines that express the T‐cell‐epitope‐rich domain of truncated latent proteins of EBV, including truncatedlatent membrane protein 2A (Trunc‐LMP2A), truncated EBV nuclear antigen 1 (Trunc‐EBNA1), and Trunc‐EBNA3A. The vaccines effectively activate both cellular and humoral immunity in mice and show promising results in suppressing tumor progression and improving survival time in tumor‐bearing mice. Furthermore, it is observed that the truncated forms of the antigens, Trunc‐LMP2A, Trunc‐EBNA1, and Trunc‐EBNA3A, are more effective than full‐length antigens in activating antigen‐specific immune responses. In summary, the findings demonstrate the effectiveness of mRNA‐based therapeutic vaccines targeting the T‐cell‐epitope‐rich domain of EBV latent proteins and providing new treatment options for EBV‐associated cancers.

AbstractSoft transparent electrodes (TEs) have received tremendous interest from academia and industry due to the rapid development of lightweight, transparent soft electronics. Metallic micro‐nano networks (MMNNs) are a class of promising soft TEs that exhibit excellent optical and electrical properties, including low sheet resistance and high optical transmittance, as well as superior mechanical properties such as softness, robustness, and desirable stability. They are genuinely interesting alternatives to conventional conductive metal oxides, which are expensive to fabricate and have limited flexibility on soft surfaces. This review summarizes state‐of‐the‐art research developments in MMNN‐based soft TEs in terms of performance specifications, fabrication methods, and application areas. The review describes the implementation of MMNN‐based soft TEs in optoelectronics, bioelectronics, tactile sensors, energy storage devices, and other applications. Finally, it presents a perspective on the technical difficulties and potential future possibilities for MMNN‐based TE development.

AbstractTumor immunotherapy offers a new paradigm to treat cancer; however, the existing regimens are accompanied by the dilemma of insufficient therapeutic outcomes and off‐target adverse effects. The intestinal immune system contains a bulk of immune cells, which can be important contributors to the maintenance of systemic immune homeostasis. However, manipulating intestinal immunity to achieve systemic anti‐tumor immunity is extremely challenging. Here, an oral immunotherapy strategy is reported using immune‐enhancing fullerenes (IEF) that can reinvigorate anti‐tumor immunity via immune cell‐metabolic reprogramming of intestinal immune cells. Findings show that IEF can remodel anti‐inflammatory macrophages into tumor‐killing macrophages by regulating the energy metabolism pathway from oxidative phosphorylation (OXPHOS) to glycolysis. Consequently, IEF can reprogram the immunosuppressive intestinal immunity and enhance sys temic immunity in vivo, thereby boosting anti‐tumor immunity and converting “cold” tumors into “hot” tumors. Oral immunotherapy strategy, modulating autoimmune cells in the intestine and achieving systemic anti‐tumor immunity, can ensure safe and efficient tumor immunotherapy.

Published: October 2023

AbstractHydrogel fibers have attracted substantial interest for application in flexible electronics due to their ionic conductivity, high specific surface area, and ease of constructing multidimensional structures. However, universal continuous spinning methods for hydrogel fibers are yet lacking. Based on the hydrophobic mold induced regional heterogeneous polymerization, a universal self‐lubricating spinning (SLS) strategy for the continuous fabrication of hydrogel fibers from monomers is developed. The universality of the SLS strategy is demonstrated by the successful spinning of 10 vinyl monomer‐based hydrogel fibers. Benefiting from the universality of the SLS strategy, the SLS strategy can be combined with pre‐gel design and post‐treatment toughening to prepare highly entangled polyacrylamide (PAM) and ionic crosslinked poly(acrylamide‐co‐acrylic acid)/Fe3+ (W‐PAMAA/Fe3+) hydrogel fibers, respectively. In particular, the W‐PAMAA/Fe3+ hydrogel fiber exhibited excellent mechanical properties (tensile stress > 4 MPa, tensile strain > 400%) even after 120 days of swelling in the pH of 3–9. Furthermore, owing to the excellent multi‐faceted performance and one‐dimensionality of W‐PAMAA/Fe3+ hydrogel fibers, flexible sensors with different dimensions and functions can be constructed bottom‐up, including the one‐dimensional (1D) strain sensor, two‐dimensional (2D) direction sensor, three‐dimensional (3D) pressure sensor, and underwater communication sensor to present the great potential of hydrogel fibers in flexible electronics.

AbstractOrganic photovoltaic (OPV) sub‐modules shall be feasible for production using halogen‐free solvents in air,high power conversion efficiencies (PCEs), and long‐term stability, which are challenging requirements. To achieve this goal, air‐processed OPVs are fabricated by employing a synthesized set of π‐conjugated polymers, NAP‐T‐SiBTZ (P1) and NAP‐TT‐SiBTZ (P2), with thiophene and thienothiophene π‐spacers, respectively. P1 and P2 incorporated ternary OPVs show excellent PCEs and are used to produce small‐area, sub‐module air‐processed devices using o‐xylene as the solvent. Interestingly, P2‐added ternary devices has remarkable PCEs of 17.62% (PM6:P2:Y7) and 17.96% (PM6:P2:L8‐BO), which is the highest reported for air‐processed OPVs. . Notably, P2‐associated ternary blends exhibit a nano‐morphology, increased charge carrier mobilities, exciton dissociation, and decreased non‐geminate recombination, which are deemed responsible for the enhanced PCEs observed. In addition, P2 demonstrates high efficiency for a thick‐film device (>300 nm), with a PCE of >16.50%. Notably, a 55 cm2 sub‐module produced by bar coating using o‐xylene in open air has a PCE of 13.88%. Additionally, P2‐containing devices demonstrate impressive thermal and photo‐stabilities. This study shows the potential of an OPV that may be used to produce low‐cost solar cell sub‐module at low cost with exceptional commercial value.

AbstractAimCapnography is recommended for use in procedural sedation and analgesia (PSA); however, limited studies assess its impact on recovery time. We investigated the association between capnography and the recovery time of PSA in the emergency department (ED).MethodsThis study was a secondary analysis of a multicenter PSA patient registry including eight hospitals in Japan. We included all patients who received PSA in the ED between May 2017 and May 2021 and divided the patients into capnography and no‐capnography groups. The primary outcome was recovery time, defined as the time from the end of the procedure to the cessation of monitoring. The log‐rank test and multivariable analysis using clustering for institutions were performed.ResultsOf the 1265 screened patients, 943 patients who received PSA were enrolled and categorized into the capnography (n = 150, 16%) and no‐capnography (n = 793, 84%) groups. The median recovery time was 40 (interquartile range [IQR]: 25–63) min in the capnography group and 30 (IQR: 14–55) min in the no‐capnography group. In the log‐rank test, the recovery time was significantly longer in the capnography group (p = 0.03) than in the no‐capnography group. In the multivariable analysis, recovery time did not differ between the two groups (adjusted hazard ratio, 0.95; 95% confidence interval, 0.77–1.17; p = 0.61).ConclusionIn this secondary analysis of the multicenter registry of PSA in Japan, capnography use did not associate with shorter recovery time in the ED.
Luminescent and Photoredox‐Active Molybdenum(0) Complexes Competitive with Isoelectronic Ruthenium(II) Polypyridines
Authors: Jin Tao , Wagner Dorothee , Wenger Oliver S. 
Published: October 2023

AbstractRuthenium(II) complexes with chelating polypyridine ligands are among the most frequently investigated compounds in photophysics and photochemistry, owing to their favorable luminescence and photoredox properties. Equally good photoluminescence performance and attractive photocatalytic behavior is now achievable with isoelectronic molybdenum(0) complexes. The zero‐valent oxidation state of molybdenum is stabilized by carbonyl or isocyanide ligands, and metal‐to‐ligand charge transfer (MLCT) excited states analogous to those in ruthenium(II) complexes can be established. Microsecond MLCT excited‐state lifetimes and photoluminescence quantum yields up to 0.2 have been achieved in solution at room temperature, and the emission wavelength has become tunable over a large range. The molybdenum(0) complexes are stronger photoreductants than ruthenium(II) polypyridines and can therefore perform more challenging chemical reductions. The triplet nature of their luminescent MLCT states allows sensitization of photon upconversion via triplet‐triplet annihilation, to convert low‐energy input radiation into higher‐energy output fluorescence. This review summarizes the current state of the art concerning luminescent molybdenum(0) complexes and highlights their application potential. Molybdenum is roughly 140 times more abundant and far cheaper than ruthenium, hence this research is relevant in the greater context of finding more sustainable alternatives to using precious and rare transition metals in photophysics and photochemistry.

Published: October 2023

AbstractThe large‐scale deployment of CO2 electroreduction is hampered by deficient carbon utilization in neutral and alkaline electrolytes due to CO2 loss into (bi)carbonates. Switching to acidic media mitigates carbonation, but suffers from low product selectivity because of hydrogen evolution. Here we report a crown ether decoration strategy on a Cu catalyst to enhance carbon utilization and selectivity of CO2 methanation under acidic conditions. Macrocyclic 18‐Crown‐6 is found to enrich potassium cations near the Cu electrode surface, simultaneously enhancing the interfacial electric field to stabilize the *CO intermediate and accelerate water dissociation to boost *CO protonation. Remarkably, the mixture of 18‐Crown‐6 and Cu nanoparticles affords a CH4 Faradaic efficiency of 51.2 % and a single pass carbon efficiency of 43.0 % toward CO2 electroreduction in electrolyte with pH=2. This study provides a facile strategy to promote CH4 selectivity and carbon utilization by modifying Cu catalysts with supramolecules.

Published: October 2023

AbstractFlame retardancy in various materials is becoming an increasingly important performance feature. In the textile industries, fire‐related problems have become an important concern over the decade. Herein, the polyvinyl alcohol (PVA) and graphene‐supported material were functionalized with trimethyl phosphate (TMP) for the synthesis of flame retardant (FR) composite material [graphene polymer functionalized trimethyl phosphate (GPTMP)] in the aqueous medium, which improves the stability of cotton fabric against flame. Graphene and PVA fabricated with phosphorus functional groups make the fabric more comfortable against fire and help to avoid further spreading of fire. The composite‐coated fabric sustains for a long time on continuous flame with maintaining its initial shape and size. The GPTMP‐coated fabric shows flame retardancy for up to 540 s on constant flame exposure, whereas control samples such as PVA‐, graphene oxide‐, and TMP‐coated fabrics resist for up to 15, 20, and 14 s, respectively. The limiting oxygen index (LOI) and vertical flammability test (VFT) for synthesized composites were performed to confirm and support the flame retardancy property of GPTMP. The GPTMP shows the 35% LOI value and forms the char length of 2.6 cm during VFT. This work provides a simple and eco‐friendly method to obtain novel GPTMP, which has a high potential as a FR for different fabrics, including cotton.
