AbstractFormamidinium lead iodide (FAPbI3) is the benchmark material for the most efficient near‐infrared perovskite light‐emitting diodes (LEDs) and a promising gain medium for perovskite‐based coherent light sources. Thus, it is crucial to understand and control its defect chemistry to harness the full potential of its exceptional radiative recombination properties. Here, this topic is addressed by tailoring the I− to Br− ratio in the perovskite composition. It is found that introducing small Br− quantities improves the yield of radiative recombination with a beneficial impact on both spontaneous and amplified spontaneous emission (ASE) and improves the semiconductor photostability leading to reduced luminescence efficiency roll‐off and enhanced radiance in LEDs. By employing photoemission electron microscopy (PEEM), this improvement in optoelectronic performance can be directly correlated to a reduced hole‐trapping activity achieved by replacing iodide with bromide, thus, providing a convenient yet powerful synthetic approach to control the defect chemistry of the material and fostering its implementation in advanced photonic platforms.

Published: December 2023

AbstractCobalt telluride, with tunable magnetism and ferromagnetism that hinged upon the stoichiometric ratio, has emerged as a new member of 2D materials in the last decade. Metallic doping by sodium (Na) and platinum (Pt) atoms below critical concentrations is found to enhance the magnetism of cobalt telluride. After thinning cobalt telluride down to few‐layer, the saturation magnetism is improved by two order of magnitudes because of the oxidation state of cobalt (Co) and reduced coordination number of the surface atoms. In 2D limit, cobalt di‐telluride possesses Dirac band structure with many nodal lines that correlate with quantum criticality and other fantastic physics. In this mini‐review, the crystal and band structures of cobalt telluride categorized by stoichiometric ratio are overviewed after briefing the introduction. Both top‐down and bottom‐up methods are then discussed to offer optimum solutions for each specified application scenario. Afterward, emerging magnetic and electronic properties and credit enhancements are launched accompanied with their key advances. Beyond these, the faced challenges and possible directions of future research are also provided, attempting to boost both fundamental physics and device applications based on 2D cobalt telluride.

AbstractThe high heterogeneity of receptor expression and varied chemotherapeutic sensitivity seriously compromise the therapeutic outcome of triple‐negative breast cancer (TNBC)‐targeting nanodrugs. In this work, a TNBC‐targeting nanodrug (designated as CPU) equipped with self‐promoted targeting property through chemotherapeutic upregulation of CD47 is constructed, enabling synergistic chemo/photodynamic therapy. Specifically, the hydrophobic docetaxel (DOC), which can upregulate the expression of CD47 in TNBC cells, is loaded in the nanomicelles (designated as P‐Pep) assembled from a protoporphyrin IX (PPIX)‐labeled amphiphilic chimeric peptide of Fmoc‐K(PPIX)‐AWSATWSNYWRH, obtaining the ca. 196 nm CPU. Aided by the enhanced permeability and retention effect and guidance of CD47‐binding peptide sequence, CPU is verified to prefer to accumulate in CD47 overexpressed TNBC cells, which can recruit more CPU by upregulating CD47 expression post‐treatment of DOC. Both in vitro and in vivo results demonstrate the superior tumor targeting ability, which can extensively amplify chemotherapeutic and photodynamic therapeutic effects while evading obvious adverse effects. The self‐promoted targeting strategy will inspire the design of nanodrugs for the personalized therapy of tumors with high heterogeneity and resistance.

AbstractPrecisely regulating surface reconstruction of copper (Cu) chalcogenides‐based catalysts to promote the multicarbon (C2+)selectivity of the electrochemical CO2reduction reaction (CO2RR) is hampered by the challenging control of the intractable anions and the optimal Cuδ+reduction (0 <δ< 1). Herein, a porous carbon‐supported copper selenides electrocatalyst that can remarkably improve the C2‐product yield and especially unveil the time‐revolved electrochemical CO2RR reconstruction process to enable the high C2‐selectivity, most notably for ethanol is constructed. The Faradic efficiency (FE) of C2‐products achieved is as high as ≈85.2% with a partial current density of 229.5 mA cm−2.Operandoinfrared spectroscopy and density functional theory (DFT) calculations unravel that the surface Se vacancies (VSe) formation brings closer the neighboring Cu+atoms and activates the Cu sites, thereby rendering efficient generation of the key intermediates (*CO and*CHO) and lowering the C–C coupling barrier for C2production. The appearance of metallic Cu can shorten the next‐nearest Cu0–Cu+distance for O atom to bridge in, leading to the preferential formation of*OC2H4towards ethanol instead of C–O bond cleavage to form ethylene. This work opens the avenue of designing suitable local atomic structures catalysts to engage the intermediates for targeted CO2RR products.

Published: December 2023

AbstractThe pulmonary vascular system plays a crucial role in maintaining normal physiological functions, and perturbations in this network often serve as indicators for various fatal diseases. Thus, accurate mapping and assessment of the intricate anatomical details of pulmonary vasculature is essential for the investigation of the underlying mechanism of these diseases. Yet it is considered a tough challenge as traditional imaging techniques offer limited representations of the vasculature network in the lung, while optical imaging methods face limitations from tissue depth. To overcome these obstacles, in this study, an AIENP‐reinforced DISCO method, for whole‐tissue 3D reconstruction of pulmonary capillaries is presented. Combining AIENPs, hydrogel‐enhanced scaffolds, and solvent‐based DISCO procedures, the method successfully visualizes the entire network of mouse pulmonary capillaries with a significantly shortened timeframe and cost. The whole process including labeling and clearing takes 6 days and it costs ≈ 5 USD to stain the lung vasculature of an adult mouse. Moreover, the study provides valuable insights for detecting pulmonary vascular abnormalities. This fast and cost‐effective technique opens new avenues for developing better fluorophores compatible with tissue optical clearing and offers insights for in‐depth research on pulmonary pathophysiology.

Published: December 2023

AbstractFast energy storage via intercalation requires quick ionic diffusion and often results in pseudocapacitive behavior. The cycling stability of such energy storage materials remains understudied despite the relevance to lifetime cost. Orthorhombic niobium oxide (T‐Nb2O5) is a rapid ion intercalation material with a theoretical capacity of 201.7 mAh g−1 (Li2Nb2O5) and good cycling stability due to the minimal unit cell strain during (de)intercalation. Prior reports of T‐Nb2O5 cycling between 1.3–3.1 V versus Li/Li+ noted a 50% loss in capacity after 10 000 cycles. Here, cyclic voltammetry is used to identify the role of the voltage window, state of charge, and potentiostatic holds on the cycling stability of mesoporous T‐Nb2O5 thin films. Films cycled between 1.2–3.0 V versus Li/Li+ without voltage holds (Li1.1Nb2O5) exhibited extreme cycling stability with 90.8% capacity retention after 0.25 million cycles without detectable morphological/crystallographic changes. In contrast, the inclusion of 60 s voltage holds (Li2.18Nb2O5) led to rapid capacity loss with 61.6% retention after 10 000 cycles with corresponding X‐ray diffraction evidence of amorphization. Cycling with other limited voltage windows identifies that most crystallographic degradation occurs at higher extents of lithiation. These results reveal remarkable stability over limited conditions and suggest that T‐Nb2O5 amorphization is associated with high extents of lithiation.

AbstractElectron tomography holds great promise as a tool for investigating the 3D morphologies and internal structures of metal‐organic framework‐based protein biocomposites (protein@MOFs). Understanding the 3D spatial arrangement of proteins within protein@MOFs is paramount for developing synthetic methods to control their spatial localization and distribution patterns within the biocomposite crystals. In this study, the naturally occurring iron oxide mineral core of the protein horse spleen ferritin (Fn) is leveraged as a contrast agent to directly observe individual proteins once encapsulated into MOFs by electron microscopy techniques. This methodology couples scanning electron microscopy, transmission electron microscopy, and electron tomography to garner detailed 2D and 3D structural interpretations of where proteins spatially lie in Fn@MOF crystals, addressing the significant gaps in understanding how synthetic conditions relate to overall protein spatial localization and aggregation. These findings collectively reveal that adjusting the ligand‐to‐metal ratios, protein concentration, and the use of denaturing agents alters how proteins are arranged, localized, and aggregated within MOF crystals.

AbstractEngineering living functional biofilms offers an ecofriendly and efficient technique for the corrosion protection of metallic materials in marine environments. Its firm attachment to the metal surface is a key step to effectively improve the corrosion protection. Herein, engineered Escherichia coli biofilm with strong metal binding ability is constructed by genetically appending a metal binding domain (MBD) to extracellular amyloids. The engineered living biofilm improved the corrosion resistance of X70 carbon steel. Moreover, a biofilm‐induced mineralization layer, mainly composed of calcite, is formed on the X70 surface, which provided a stable corrosion barrier. At the end of 7‐days immersion, the icorr decreased from 5.1 ± 0.4 µA cm−2 without biofilm to 0.5 ± 0.1 µA cm−2 with E. coli MBD biofilm, resulting in a corrosion inhibition efficiency of 90.2%. It also demonstrated the corrosion protection effect for 304 stainless steel, suggesting possible broad applications of the engineered biofilm. The application of synthetic biology offers a novel approach in the development of anti‐corrosion technologies in water environments.

AbstractPhotosensitizers (PSs) with effective reactive oxygen species generation ability against hypoxia are of great potential for clinical treatment of malignant tumors. However, complex tumor microenvironment, such as antioxidative responses and immunosuppression, would ineluctably limit the efficiency of photodynamic therapy (PDT). Herein, a molecular‐targeting photosensitizer QTANHOH is rationally designed for histone deacetylases (HDACs‐targeting photo‐immunotherapy application. The PS QTANHOH displays excellent type‐I/II PDT performance, exhibiting significant phototoxicity toward cancer cells with half maximal inhibitory concentration (IC50) less than 10 nm in both normoxia and hypoxia conditions under blue laser irradiation. Moreover, the bioactive compound could inhibit HDACs and activate the immune microenvironment to boost PDT efficacy on the immunocompetent BALB/c mice with breast cancer, leading to the eradication of solid tumor and inhibition of metastasis. Notably, the molecular‐targeting photosensitizer introduces an alternative strategy to achieve superior phototherapy for cancer therapy.

Published: December 2023

AbstractThe proliferation of rechargeable lithium‐ion batteries (LIBs) over the past decade has led to a significant increase in the number of electric vehicles (EVs) powered by these batteries reaching the end of their lifespan. With retired EVs becoming more prevalent, recycling and reusing their components, particularly graphite, has become imperative as the world transitions toward electric mobility. Graphite constitutes ≈20% of LIBs by weight, making it a valuable resource to be conserved. This review presents an in‐depth analysis of the current global graphite mining landscape and explores potential opportunities for the “second life” of graphitefrom depleted LIBs. Various recycling and reactivation technologies in both industry and academia are discussed, along with potential applications for recycled graphite forming a vital aspect of the waste management hierarchy. Furthermore, this review addresses the future challenges faced by the recycling industry in dealing with expired LIBs, encompassing environmental, economic, legal, and regulatory considerations. In conclusion, this review provides a comprehensive overview of the developments in recycling and reusing graphite from retired LIBs, offering valuable insights for forthcoming large‐scale recycling efforts.

AbstractThe acidic aqueous supercapacitors have been found to deliver appealing capacitive properties due to fast ion diffusion caused by the applied smallest size of hydrion. However, their practical applications are largely inhibited by the narrow electrochemical stability window of water (1.23 V). Herein, A nitrogen‐enriched porous carbon materials (RNOPCs) is reported, consisting of varied nitrogen doping bonded on sp2 and sp3 carbon sites, which are capable of stimulating a wider potential window up to 1.4 V and thus resulting in a great enhancement of capacitive performance in aqueous acidic electrolytes. Together with the improved electrical conductivity and preferable hydrion diffusion, RNOPCs exhibit an ultrahigh volumetric capacitance (1084 F cm−3) in 0.5 M H2SO4. Besides, a fully packed RNOPCs‐based symmetrical supercapacitor can deliver a high gravimetric and volumetric energy density of 31.8 Wh Kg−1 and 54.3 Wh L−1 respectively, approaching those of lead acid batteries (25–35 Wh Kg−1). The first‐principles calculations reveal that the lone pair electrons of the doped nitrogen can be delocalized on its neighboring carbon atoms, improving charge uptakes and overpotentials. Such facile and scale‐up production of carbon‐based supercapacitors can bridge the gap of energy density between traditional supercapacitors and batteries in aqueous electrolytes.

AbstractGuided bone regeneration gathers significant interest in the realm of bone tissue engineering; however, the interplay between membrane thickness and permeability continues to pose a challenge that can be addressed by the water‐collecting mechanism of spider silk, where water droplets efficiently move from smooth filaments to rough conical nodules. Inspired by the natural design of spider silk, an innovative silk fibroin membrane is developed featuring directional fluid transportation via harmoniously integrating a smooth, dense layer with a rough, loose layer; conical microchannels are engineered in the smooth and compact layer. Consequently, double‐layered membranes with cone‐shaped microporous passageways (CSMP‐DSF membrane) are designed for in situ bone repair. Through extensive in vitro testing, it is noted that the CSMP‐DSF membrane guides liquid flow from the compact layer's surface to the loose layer, enabling rapid diffusion. Remarkably, the CSMP‐DSF membrane demonstrates superior mechanical properties and resistance to bacterial adhesion. When applied in vivo, the CSMP‐DSF membrane achieves results on par with the commercial Bio‐Gide collagen membranes. This innovative integration of a cross‐thickness wetting gradient structure offers a novel solution, harmonizing the often‐conflicting requirements of material transport, mechanical strength, and barrier effectiveness, while also addressing issues related to tissue engineering scaffold perfusion.

AbstractAnionic modification engineering is a crucial approach to develop highly efficient electrocatalysts for hydrogen evolution reaction. Herein, halogen elements (X = Cl, Br, and I)‐modified Ru‐based nanosheets (X‐Ru/RuP2) are designed by rapid and eco‐friendly microwave‐phosphide plasma approach within 60 s. Experimental and density functional theory calculations verify that the introduced halogen element, especially Br, can optimize the surface intermediates adsorption. Specially, the designed Br‐Ru/RuP2 favors the water dissociation and following hydrogen adsorption/desorption process. Then, the as‐synthesized Br‐Ru/RuP2 exhibits low overpotential of 34 mV to reach 10 mA cm−2 coupled with small Tafel slope of 27 mV dec−1 in alkaline electrolyte with excellent long‐term stability. Moreover, the electrocatalytic performances in acid and neutral media are also boosted via Br element modification. This work paves a novel way to regulate the electronic structure of Ru‐based compounds, and then can boost the electrocatalytic kinetics.

AbstractUpconversion (UC) phosphors exhibiting luminescence color tuning (LCT) through variations in infrared excitation intensity offer great potential for high‐security anti‐counterfeiting applications. However, the current LCT capability is limited to high excitation intensities, hindering developments of non‐invasive counterfeit detection. In this study, two orders of magnitude reduction are achieved in excitation intensities for LCT in YF3:Yb/Er, accomplished by attaining an unprecedentedly efficient three‐photon excited red emission for mixing with the two‐photon excited green emission. To enable this breakthrough, deoxygenation techniques are employed during sample preparations, which surprisingly prevent concentration quenching of Yb3+ ions, facilitating efficient three‐photon excitation of the red emission for Yb3+ concentrations ≥ 30% even at excitation intensities as low as 10 mW cm−2. At excitation intensities of 100 mW cm−2, the three‐photon excitation contributes to 91–94% of the red emission, resulting in an 11–17‐fold increase in the red‐to‐green intensity ratio. This low‐excitation‐induced LCT, shifting from green to orange, showcases its potential for anti‐counterfeiting. Furthermore, present YF3:Yb/Er phosphors demonstrate an impressive UC quantum yield of 7.8%, surpassing the popular NaYF4:Yb/Er phosphor (5.6%) under the same excitation intensity of 31.8 W cm−2. These findings represent a significant advancement in highly efficient UC fluoride phosphors, promising diverse applications across various fields.

AbstractThe extensive use and misuse of antibiotics have resulted in bacterial resistance becoming increasing commonplace. Essential oils (EOs) are known to possess antimicrobial properties and therefore have many potential practical applications. However, the default of hydrophobicity, chemical instability, and volatility limit scope of application. Encapsulation of EOs in colloidal delivery systems can mitigate these challenges and allow for greater efficacy. A homogenous nanoemulsion (HS15‐CE) containing a combination of eucalyptol (Euc) and cefradine (Cef) is developed to explore its synergistic effect on antibacterial activity and potentially reduce the amount of antibiotic required to treat bacterial infections. The HS15‐CE nanoemulsion displays a synergistic effect on the inhibition of Escherichia coli (E. coli) growth in vitro, significantly decreasing the minimum inhibitory concentration (MIC) by eight times. The ex vivo imaging reveals high accumulation concentrations and long retention in bladders. Moreover, the nanoemulsion alleviates the E. coli induced cystitis infection, as evidenced by decreased bacterial colonies in urine, reduced inflammatory cytokines, and increased expression of tight junctional protein ZO‐1. These findings suggest the potential of the HS15‐CE nanoemulsion in providing a synergistic effect for the treatment of bacterial urocystitis.
