AbstractDendritic cell (DC) vaccines play an important role in anti‐tumor immunotherapy. Tumor‐associated cells or cytokines in the tumor microenvironment (TME) can inhibit the antigen‐presenting function of DC. Immunogenic cell death (ICD) can enhance the uptake and presentation of tumor antigens by DC. This study investigates the maturation mechanism of DC induced by low‐temperature plasma (LTP), as well as the therapeutic and protective effects of LTP‐induced DC vaccine in a tumor model. DC2.4 that is co‐cultured with LTP‐treated B16F10 (LTP‐B16) or with these supernatants exhibited decreased phagocytic activity, increased production of cytokines (IL‐12, IL‐6, TNF‐α, and IL‐1β), and increased expression of cell surface activation markers (CD80, CD86, and MHC II). The expression of CD80+/CD86+ is decreased after pre‐treatment with TLR4 and NF‐κB (p65) inhibitors, respectively. In vivo, trials indicated that the LTP‐induced DC vaccine‐induced anti‐tumor immunity and, when combined with cisplatin, synergistically reduced tumor growth.

AbstractExcessive scar formation is a major complication of wound healing. Premature release of anti‐scarring drugs can negatively impact healing. This study aims to develop a targeted delivery system for the controlled release of anti‐scarring drugs during the scar formation stage. Solid lipid nanoparticles (SLNs) coated with Clathrin, a cage‐like protein, to prevent premature drug release is developed. Insulin‐like growth factor (IGF) is conjugated to the SLNs for targeted delivery via its affinity for connective tissue growth factor (CTGF), a protein overexpressed during scar formation. The IGF‐Clathrin‐SLNs exhibited a size of 300 ± 20 nm and a zeta potential of 9.23 ± 0.4 mV. In vitro studies demonstrated sustained release of the encapsulated drug‐ kynurenic acid; less than 10% of kynurenic acid is released within three days, while over 50% is released within 10 h upon Clathrin removal using a surfactant at pH 8. Cellular uptake studies confirmed targeting efficacy. Fibroblasts with low CTGF expression displayed low uptake (<10%), whereas MCF7 cells with high CTGF expression showed significantly higher uptake (80%). This work demonstrates a promising targeted delivery platform for the controlled release of anti‐scarring drugs during scar formation.

Published: September 2024

AbstractTemporomandibular joint osteoarthritis (TMJOA) is a commonly encountered degenerative joint disease in oral and maxillofacial surgery. Recent studies have shown that the excessive unbalanced activation of Wnt/β‐catenin signaling is connected with the pathogenesis of TMJOA and due to the inability to inhibit the over‐activated Wnt pathway, while Wnt16‐deficient mice has a more severe Knee OA. However, the efficacy of direct intra‐TMJ injection of Wnt16 for the relief of TMJOA is still not directly confirmed. Moreover, small‐molecule drugs such as Wnt16 usually exhibit short‐lived efficacy and poor treatment adherence. Therefore, in order to obtain a stable release of Wnt16 both in the short and long term, this study fabricates a double‐layer slow‐release Wnt16 carrier based on mesoporous silica nanospheres (MSNs) encased within hyaluronic acid (HA) hydrogels. The biofunctional hydrogel HA/Wnt16@MSN is analyzed both in vitro and in vivo to evaluate the treatment of TMJOA. As a result, it shows superior pro‐cartilage matrix restoration and inhibition of osteoclastogenesis ability, and effectively inhibits the over‐activation of the Wnt/β‐catenin pathway. Taken together, biofunctional hydrogel HA/Wnt16@MSN is a promising candidate for the treatment of TMJOA.

AbstractDespite advancements in therapeutic agents for diabetic chronic wounds, challenges such as suboptimal bioavailability, intricate disease milieus, and inadequate delivery efficacy have impeded treatment outcomes. Here, ultrasound‐responsive hydrogel incorporated with heparin‐binding domain (HBD) peptide nanoparticles is developed to promote diabetic wound healing. HBD peptide, derived from von Willebrand Factor with angiogenic activity, are first engineered to self‐assemble into nanoparticles with enhanced biostability and bioavailability. Ultrasound responsive cargo release and hydrogel collapses are first verified through breakage of crosslinking. In addition, desired antioxidant and antibacterial activity of such hydrogel is observed. Moreover, the degradation of hydrogel under ultrasound stimulation into smaller fragments facilitated the deeper wound penetration of ≈400 µm depth. Complete wound closure is observed from diabetic mice with chronic wounds after being treated with the proposed hydrogel. In detail, in vivo studies revealed that hydrogels loaded with HBD peptide nanoparticles increased the levels of angiogenesis‐related growth factors (VEGF‐A, CD31, and α‐SMA) to effectively accelerate wound repair. Overall, this study demonstrates that ultrasound‐responsive HBD peptide hydrogel provides a synergistic therapeutic strategy for external biofilm elimination and internal effective delivery for diabetic wounds with biofilm infection.

AbstractElectro‐resistance (ER) plays a crucial role in the application of hafnia‐based ferroelectric tunnel junctions (FTJs), pivotal devices widely acknowledge for their potential in non‐volatile memory and neuromorphic networks. Leveraging atomic layer deposition (ALD) enhances the flexibility in fabricating bilayer FTJs by combining a ferroelectric layer with another oxide layer. Introducing additional layers is necessary to achieve a sufficient storage window for implementing intriguing functions, albeit at the risk of increased depolarization field strength. Hence, selecting a suitable inserted layer becomes paramount. In this study, a novel strategy to enhance the performance of Ge‐based Hf0.5Zr0.5O2 FTJs is presented by incorporating bottom interfacial layers (ILs) with distinct band energy characteristics. The optimized FTJs exhibit significantly improved endurance, lower coercive voltage, and enhanced retention properties. Notably, an intriguing asymmetric retention behavior driven by the imprint field (Eimp) is observed, which can be mitigated by integrating TiO2 ILs. Most importantly, an effective method to manipulate depolarization behavior in hafnia‐based devices through ILs is introduced, leading to enhanced non‐volatility and synaptic behavior in FTJs.

AbstractSodium metal batteries (SMBs), the next‐generation advanced secondary batteries, have attracted extensive attention due to their low cost and high energy density. However, the unavoidable interfacial side reactions and uncontrollable dendrite growth severely restrict their practical application. In this work, a Na (100)‐textured composite anode embedded with antimony‐doped tin oxide (ATO) nanoparticles (ATO‐12Na) is innovatively designed via an accumulative roll bonding technique. It is observed that the Na (100) texture not only contributes to the formation of anion‐derived inorganic‐rich solid electrolyte interphase layer on the surface of ATO‐12Na composite anode but also efficiently induces the uniform and horizontal Na deposition during the pre‐deposition stage. Profiting from the intrinsic Na affinity of Na (100) texture and the high sodiophilicity of ATO active sites, the integrated composite anode exhibits enhanced interfacial compatibility and excellent Na plating/stripping stability. At 2 mA cm−2, the ATO‐12Na symmetric cell can operate steadily for more than 1400 h. The full cell assembled by ATO‐12Na anode and Na3V2(PO4)3 cathode delivers impressive long‐term cycling stability over 4500 cycles at 500 mA g−1 with a high capacity retention of 80.7%. This study offers a new approach to designing ultra‐stable, dendrite‐free, and high‐performance SMBs.

AbstractAqueous zinc‐iodine (Zn─I2) battery is a promising energy storage system due to its inherent safety, high theoretical capacity, sustainability, and cost‐effectiveness. However, the shuttle effect of polyiodide severely affects the stable loading of active iodine and even accelerates the corrosion of the Zn anode, thus impeding its further advancement. Herein, a unique trimethylsulfonium cation (TMS+) with strong adsorption is proposed to stabilize both the iodine cathode and Zn anode. Benefiting from the robust interaction between TMS+ and polyiodide, the electrolyte can effectively immobilize large‐capacity iodine in the form of oily precipitate, thus avoiding the shuttle effect of polyiodide and the Zn corrosion. Additionally, TMS+ can be preferentially adsorbed on various Zn facets, inducing an electrostatic shielding effect to inhibit Zn dendrite growth. Consequently, Zn anode can be stably cycled over 3400 h at 5 mA cm−2/5 mAh cm−2, and a large areal capacity of 2.71 mAh cm−2 as well as long‐life stability over 6400 cycles is achieved for Zn─I2 battery. Furthermore, cation adsorption engineering is practically utilized in pouch cells, realizing superior fast‐charging stability over 790 cycles. This electrolyte modification with dual stabilizations is anticipated to be applied to other metal‐iodine batteries as a cost‐effective, facile, and safe strategy.

AbstractThe oxidation of iodide ions during annealing in air and rich defects generated at crystal terminations in perovskite are major limitations for achieving high photovoltaic performance in printable mesoscopic perovskite solar cells (p‐MPSCs). Here, the dual role of hydrazide derivatives in inhibiting iodide oxidation and passivating crystal termination defects is reported and how the dual role is affected by the substituent is studied. It's found that varying the hydrazide derivative from formylhydrazine (FH) to benzhydrazide (BH) and then to 4‐tert‐butylbenzhydrazide (TBBH) by introducing phenyl and 4‐tert‐butylphenyl substituents enhances the electron donating ability of hydrazides due to substituent electronic effect. The tailored hydrazides present enhanced iodide oxidation suppression and defect passivation capabilities, which lowers the trap density of perovskite in p‐MPSCs significantly. As the most effective additive, TBBH improves the power conversion efficiency of the p‐MPSC from 18.66% to 20.30%, and the resulted device maintains 90% of its initial efficiency after 500 h tacking at maximum power point at 55 ± 5 °C under simulated 1 sun illumination.

Published: September 2024

AbstractThe significant interfacial resistance between solid electrolyte‐electrode interfaces is a major bottleneck for the practical application of solid‐state lithium batteries. This resistance is primarily caused by the formation of space charge layers (SCLs), resulting from the redistribution of ionic carriers at the interface between dissimilar materials with varying chemical potentials, which lead to insufficient carriers and sluggish lithium‐ion transport. In this study, a conjugated structure polymer is constructed through in situ polymerization onto the oxide electrolyte, forming charge‐rich SCLs on the organic/inorganic interface, and enabling the interfacial layer to maintain superior ion transfer and contact. The Li solid NMR spectra and computational study suggest that optimized SCLs offer effective pathways for Li+ conduction in the electrolyte, thereby enhancing the interfacial conduction. Furthermore, the designed electrolyte induces the formation of an inorganic‐rich interphase layer on the lithium anode, enabling rapid lithium‐ion transport and uniform Li deposition. Consequently, the lithium symmetric cell with this electrolyte operates for more than 5100 h, while LiFePO4/Li solid‐state batteries can stably cycle up to 800 times at 5 C. This interfacial modification strategy provides a new perspective for the rational design of the charge‐rich SCLs and advances the understanding of the SCLs inside the electrolyte.

AbstractIn right‐sided colon cancer surgery, lymph node dissection around the superior mesenteric artery is necessary but technically challenging. Here we introduce the concept of “outermost layer‐oriented robotic surgery” to improve the safety, efficacy, and reproducibility of superior mesenteric artery nodal dissection. In this procedure, the thin, loose connective tissue layer between the autonomic nerve sheath of the superior mesenteric artery and adipose tissue bearing lymph nodes, termed “the outermost layer of the autonomic nerve,” is dissected. The procedure exposes the outermost layer of the nerve plexus covering the surface of the superior mesenteric artery with a width of approximately 1 cm, enabling direct visualization of the anatomy of the main arteries and, if they exist, jejunal veins which cross the superior mesenteric artery ventrally. This allows for sufficient dissection of main lymph nodes at the roots of the ileocolic artery, right colic artery, and middle colic artery and minimizes the risk of unforeseen bleeding. Thirty‐nine patients underwent robotic right hemicolectomy with this procedure. No intraoperative complications were observed. The median number of dissected lymph nodes was 50, including 16 main lymph nodes. The median operative time was 284 min, blood loss was 50 mL, and the median postoperative hospital stay was 8 days. Postoperative complications included two cases of Clavien–Dindo classification grade II, with no cases of grade III or higher. Chylous leakage as well as intractable diarrhea were not observed in any case. These findings demonstrate that the procedure can achieve safe and reliable lymph node clearance.

Published: September 2024

AbstractBorylated indoles are versatile building blocks for functional molecules, such as pharmaceutical and natural products. However, the C−H borylation regioselectivity of unprotected indoles with seven distinct sites has been a problem for a long time. Among the various synthetic approaches to borylated indoles, transition‐metal‐catalyzed, electrophilic C−H borylation and chelation effect directed C−H borylation are attractive methods because of their powerful ability to rapidly construct various C−H borylation of indoles. In this review, we highlight the developments in the C−H borylation regioselectivity of indole using these methods of C−H borylation over the last 20 years. With a focus on the mechanism of the C−H borylation of indole, further studies and developments of this field would be inspired in the future.

AbstractThe existing electronic waste (e‐waste) and leaching solutions generated by industries accumulate significant amounts of gold (Au), even in excess of those in natural minerals. Therefore, the recycling of Au is extremely significant for the potential sustainability of chemical industry. By designing ionic covalent organic frameworks (COFs), here we synthesize a series of Ionic‐COF‐X (X=Cl−, Br−, AcO−, and SO42−) by anion regulation strategy and further explore their adsorption performance towards Au recovery. All these ionic COFs exhibit ultrahigh gold adsorption efficiency and excellent regeneration. Moreover, anion regulation could indeed affect the Au capture performance. In particular, when Cl− ions serve as counter ions, the Au capacity of Ionic‐COF‐Cl could reach 1270.8 mg g−1. Moreover, in the actual CPU leaching solution test, the selectivity of Ionic‐COF‐Cl towards Au3+ ion hits 39000 and 4600 times higher than that of Cu2+ and Ni2+ ions, respectively, suggesting that the Ionic‐COF‐Cl is a promising material for highly selective recovering gold from actual e‐waste. DFT calculations further reveal that counter ions can regulate the adsorption affinity of ionic COF framework toward Au. In short, this work provides a useful anion regulation strategy to design ionic COFs as a promising platform for gold selective recovery from actual e‐waste.

Published: September 2024

AbstractMethylation and alkylation are important techniques used for the synthesis and derivatisation of small molecules and natural products. Application of S‐adenosylmethionine (SAM)‐dependent methyltransferases (MTs) in biotechnological hosts such as Escherichia coli lowers the environmental impact of alkylation compared to chemical synthesis and facilitates regio‐ and chemoselective alkyl chain transfer. Here, we address the limiting factor for SAM synthesis, methionine supply, to accelerate in vivo methylation activity. Introduction of the direct sulfurylation pathway, consisting of O‐acetylhomoserine sulfhydrolase (ScOAHS) and O‐acetyltransferase (ScMET2), from S. cerevisiae into E. coli and supplementation with methanethiol or the corresponding disulfide improves atom‐economic methylation activity in three different MT reactions. Up to 17‐fold increase of conversion compared to the sole expression of the MT and incorporation of up to 79 % of the thiol compound added were achieved. Promiscuity of ScOAHS allowed in vivo production of methionine analogues from organic thiols. Further co‐overproduction of a methionine adenosyltransferase yielded SAM analogues which were further transferred by MTs onto different substrates. For methylation of non‐physiological substrates, conversion rates up to 73 % were achieved, with an isolated yield of 41 % for N‐methyl‐2,5‐aminonitrophenol. The here described technique enables E. coli to become a biotechnological host for improved methylation and selective alkylation reactions.

AbstractWhile natural channels respond to external stimuli to regulate ion concentration across cell membranes, creating a synthetic version remains challenging. Here, we present a photo‐responsive uncaging technique within an artificial ion channel system, which activates the ion transport process from a transport‐inactive o‐nitrobenzyl‐based caged system. From the comparative ion transport screening, 1 b emerged as the most active transporter. Interestingly, its bis(o‐nitrobenzyl) derivative, i.e., protransporter 1 b′ was inefficient in transporting ions. Detailed transport studies indicated that compound 1 b is an anion selective transporter with a prominent selectivity towards chloride ions by following the antiport mechanism. Compound 1 b′ did not form an ion channel, but after the o‐nitrobenzyl groups were photocleaved, it released 1 b, forming a transmembrane ion channel. The channel exhibited an average diameter of 6.5±0.2 Å and a permeability ratio of
. The geometry‐optimization of protransporter 1 b′ indicated significant non‐planarity, corroborating its inefficient self‐assembly. In contrast, the crystal structure of 1 b demonstrates strong self‐assembly via the formation of an intermolecular H‐bond. Geometry optimization studies revealed the plausible self‐assembled channel model and the interactions between the channel and chloride ion.

Published: September 2024

AbstractThe surface engineering of electrocatalysts is one of the promising strategies to increase the intrinsic activity of electrocatalysts. It generates anion/cation vacancy defects and increases the electrochemically active surface area. We describe the surface engineering of Ni2P to favorably tune the bifunctional oxygen electrocatalytic activity and the development of a rechargeable zinc‐air battery (ZAB). Ni2P encapsulated with N and P‐dual doped carbon (Ni2P@NPC) is synthesized using a single‐source precursor complex tris‐(2,2′‐bipyridine)nickel(II) bis(hexafluorophosphate). The surface engineering of the as‐synthesized Ni2P@NPC catalyst is achieved by the controlled acid treatment at room temperature. The surface engineering removes the carbon debris and opens the pores, exfoliates the encapsulating carbon layer, increases the P‐vacancy in the crystal lattice, and boosts the electrochemically active surface area. The surface‐engineered catalyst exhibits enhanced bifunctional activity towards oxygen reduction reaction (ORR) and oxygen evolution reaction (OER). The electrocatalytically active sites of engineered catalysts are highly accessible for facilitated electron transfer kinetics. P‐vacancy favors the facile formation of defect‐rich OER active metal oxyhydroxide species. The rechargeable ZAB based on the engineered catalyst delivers a specific capacity of 770.25 mA h gZn−1, energy density of 692 Wh kgZn−1, and excellent charge‐discharge cycling performance with negligible voltaic efficiency loss (0.6 %) after 100 h.
