Published: December 2024

AbstractThe ability to rapidly charge batteries is crucial for widespread electrification across a number of key sectors, including transportation, grid storage, and portable electronics. Nevertheless, conventional Li‐ion batteries with organic liquid electrolytes face significant technical challenges in achieving rapid charging rates without sacrificing electrochemical efficiency and safety. Solid‐state batteries (SSBs) offer intrinsic stability and safety over their liquid counterparts, which can potentially bring exciting opportunities for fast charging applications. Yet realizing fast‐charging SSBs remains challenging due to several fundamental obstacles, including slow Li+ transport within solid electrolytes, sluggish kinetics with the electrodes, poor electrode/electrolyte interfacial contact, as well as the growth of Li dendrites. This article examines fast‐charging SSB challenges through a comprehensive review of materials and strategies for solid electrolytes (ceramics, polymers, and composites), electrodes, and their composites. In particular, methods to enhance ion transport through crystal structure engineering, compositional control, and microstructure optimization are analyzed. The review also addresses interface/interphase chemistry and Li+ transport mechanisms, providing insights to guide material design and interface optimization for next‐generation fast‐charging SSBs.

Published: December 2024

AbstractLead halide perovskite nanocrystals (PNCs) combine properties required by high‐quality light sources like high brightness, color purity, defects tolerance, and tunable emission wavelength. Notably, their nanoscale size enables integration or fabrication into micro/nano light‐emitting devices, which have significant market demand. However, the stability of PNCs remains an open issue for their industrialization. Chemically stable and transparent amorphous silica (SiO2), an ideal cladding for vulnerable optical materials, is widely utilized to expand the applications of PNCs, resulting in many composites. Nevertheless, current composites remain far from achieving a sufficiently stable high‐quality luminescent unit, and the specific challenges in PNCs‐SiO2 integration have not been clearly outlined. To provide inspiration for this field, iodine‐containing PNCs are used as a representative example to deliver a comprehensive review of PNCs‐SiO2 development. First, the performance advantages, prospects, and stability challenges of PNCs are analyzed, with a focus on typical cesium lead iodine nanocrystals. Next, the benefits of SiO2 encapsulation are highlighted and the design, synthesis, and performance improvement of current iodine‐containing PNCs‐SiO2 composites are systematically summarized. Finally, optimism about the potential of single‐particle encapsulation technology for PNCs is expressed and the challenges and future directions in this field are outlined.

AbstractWith the development and application of cryogenic technology, the demand for temperature measurement in cryogenic environment is increasing. Optical sensing can provide a non‐contact method of temperature measurement in cryogenic environments. Herein, a new temperature measurement route based on the persistent luminescence is proposed. The single‐component, coordination crystal Zn‐ddcphpy with electron donor and acceptor structures, achieving persistent luminescence (6–7 s) after irradiating by ultraviolet light source at 80 K. The persistent luminescence decay and electron paramagnetic resonance show that the reason for the persistent luminescence generation is the photogenerated charge separation and recombination. In cryogenic environment controlled by liquid nitrogen (80–260 K), the persistent luminescence duration decreases with increasing temperature, the color gradually changes from green to yellow with the spectrum red‐shift. Taking Zn‐ddcphpy as a model material, the unquiet temperature sensitive based persistent luminescence shows convenience, intuitive and inexpensive. Furthermore, the LPL (long‐persistent luminescence) of Zn‐ddcphpy exhibits high sensitivity and responsiveness to temperature at cryonic environment, make it suitable for temperature measurement on real time. In this work, the change of duration and color can indicate temperature without contact, which can be used for temperature measurement and monitoring in the fields of cryogenic wind tunnels, cold chain storage, etc.

AbstractFluorescent probes are functional molecules whose fluorescent properties are transformed as a response to specific stimuli. Understanding the mechanisms of these transformations is essential for the design of these stimuli‐responsive fluorescent probes. A rational design strategy has been developed to construct stimuli‐responsive supramolecular cluster fluorescent probes. They operate by a new mechanism called self‐assembly induced lactone formation (SAILac) to control the fluorescence properties of SNARF, an asymmetric xanthene fluorophore. Here, to expand SAILac applicability, the structure‐activity relationship of the fluorophore scaffold is studied. SNARF‐OBn(pNO2), designed as nitroreductase‐reactive fluorescent probe based on the SAILac mechanism, is selected as the initial structure. As the result of the structure‐activity relationship studies, a new nitroreductase‐reactive fluorescent probe, Rhodol‐OBn(pNO2), is created, having a superior signal‐to‐noise (S/N) ratio with higher reactivity toward nitroreductase than the original probe. By using Rhodol‐OBn (pNO2), the activity of endogenous nitroreductase in Escherichia coli is successfully detected.

AbstractThermally activated delayed fluorescence (TADF) emitters have garnered much attention due to 100% exciton utilization and toxic metal‐free design but often experience concentration‐quenching, requiring dispersion into the host matrix. Developing emitters that maintain consistent performance and emission wavelength irrespective of the concentration remains a significant challenge. Herein, two TADF emitters (2BPy‐pTC and 2BPy‐oTC) are designed and synthesized. The nature and energetics of the lowest excited singlet (S1) and triplet (T1) along with the extent of through‐bond exciton transfer (TBET) and through‐space exciton transfer (TSET) are unveiled using reliable quantum‐chemical calculations. While 2BPy‐pTC exhibits pre‐dominantly TBET, a greater extent of TSET is found in 2BPy‐oTC. Both emitters show a low singlet‐triplet energy gap (ΔEST), 0.21 eV for 2BPy‐pTC and 0.02 eV for 2BPy‐oTC. For 2BPy‐pTC, increasing the emitter concentration from 5 to 100 wt.% causes a bathochromic shift in the electroluminescence (EL) peak (467 to 495 nm) and a drop in maximum external quantum efficiency (EQEmax) from 12.0% to 5.5%. In contrast, 2BPy‐oTC maintains EL maxima of 500 nm and consistent EQEmax (24.0% – 27.2%) while increasing emitter concentration, acting as a universal emitter for both doped and non‐doped OLEDs and eliminating the need for tedious co‐deposition.

AbstractAchieving high‐efficiency and narrowband deep‐blue emission is of great significance for organic light‐emitting diodes (OLEDs). Herein, a novel selenium‐containing spiro‐acridine donor, DspiroSe, is designed for constructing highly efficient blue emitters. The spiro structure of DspiroSe contributes to suppressed aggregation‐caused quenching, while the selenium atom provides heavy‐atom effect. By attaching DspiroSe to a multiple resonance skeleton with different linkage strategies, two isomeric emitters sSeDDBN and PsSe‐DABNA are obtained, which show promise as candidates for blue OLEDs. Note that the different linkage methods of DspiroSe enable tuning of the emission spectrum from sky‐blue to deep‐blue, with PsSe‐DABNA demonstrating exceptional deep‐blue emission characterized by a full‐width at half‐maximum of 18 nm and a peak wavelength of 445 nm in solution. Both sSeDDBN and PsSe‐DABNA exhibit high photoluminescence quantum yields exceeding 90% in films, and OLEDs using them as emitters achieve maximum external quantum efficiencies (EQEmax) of 26.5% and 14.6%, respectively. By utilizing a TADF assistant host, the EQEmax further increases to 28.5% for sSeDDBN and 19.1% for PsSe‐DABNA. Notably, PsSe‐DABNA based OLEDs exhibit excellent color purity with Commission Internationale de l'Eclairage coordinates of (0.145, 0.052), closely approaching the BT.2020 blue standard.

AbstractMultiple‐resonance (MR) type emitters have overcome several issues in organic light‐emitting diodes (OLEDs) because of their narrowband emission and high electroluminescence quantum yield efficiency. Also, this kind of emitters has been widely used as hyperfluorescence (HF)‐OLEDs thanks to their advantageous properties. However, there has been a significant challenge for HF‐OLEDs based on MR emitters, which is impacted by the nature of the long‐lived triplet excitons of MR emitters, as there is a trade‐off between narrowband emission and short exciton lifetime. Herein, the low‐possessed triplet energy level of pyrene is introduced to an MR core unit to achieve stable HF‐OLEDs with the development of three isomers to investigate the regioisomer effect of pyrenes. The improved device lifetimes are successfully achieved, and the reasons for the differences in excimer formation and stability between those three isomers are studied.

Published: December 2024

AbstractHexagonal boron nitride (hBN) has recently emerged as a promising platform for hosting quantum emitters (QEs) in atomically thin solid‐state materials, as it operates at room temperature, possess exceptional brightness, and the two‐dimensional nature of hBN enables versatile integration with various photonic elements compared to bulk hosts. However, high‐yield fabrication of site‐specific QEs at designated locations still requires complicated pre‐ or post‐processes. In this work, QEs are created in defect‐free exfoliated hBN through localized stress application in series. Indentation is performed at target positions within the hBN flakes of various thickness without any subsequent post‐treatment, resulting in quantum emission from the majority of the indented regions. This technique yields 73% of QE generation per predefined indented site at optimized conditions, highly exceeding the 30–40% yield of previously reported top‐down approaches. In addition, the zero phonon line wavelengths of stress‐induced QEs are focused at 595 ± 18.9 nm, which implies that the emitters originate from the same family of defects. The facile one‐step, on‐demand, and high‐yield fabrication of QE arrays opens the possibility to realize scalable quantum light sources integrated on chip‐scale quantum photonic circuits.

AbstractEffective antiviral drug delivery systems, such as for 4′‐Fluorouridine (4′‐FlU), are crucial for addressing viral infections like COVID‐19. This study used ab‐initio analysis to examine interactions between 4′‐FlU and graphene oxide (GO)‐based carriers, with and without polyethylene glycol (PEG) functionalization, across various physiological conditions. Non‐PEGylated GO showed strong gas‐phase binding (−103.36 kcal mol−1), supporting systemic stability, while PEGylation reduced aqueous‐phase binding (−33.72 kcal mol−1), enhancing biocompatibility and circulation. Adsorption energies were significant in acidic and alkaline environments, with PEGylation intensifying alkaline interactions (−118.42 kcal mol−1). Charge transfer dynamics, influenced by pH and PEGylation, revealed enhanced stability under acidic conditions, suitable for tumor microenvironments. Hydrogen bonding stabilized GO‐drug complexes, ensuring prolonged release. PEGylated GO excelled in acidic environments, especially for tumor delivery, as confirmed by miscibility studies and controlled release kinetics. Thermodynamic and quantum chemical analyses highlighted environmental factors and PEGylation in optimizing stability and reactivity. GO/PEG‐4′‐FlU is ideal for localized drug delivery in acidic tumors, while GO/4′‐FlU supports systemic delivery requiring broader dispersion. This research lays the groundwork for nanotechnology‐based antiviral strategies and the design of adaptable drug delivery systems for both systemic and localized applications.

Published: December 2024

AbstractAchieving both high ionic conductance and stable Zn metal anode simultaneously remains a challenge with current liquid and solid electrolytes. Here, a viscoelastic soft solid electrolyte (VSSE) strategy is presented that effectively balances Zn ion conduction and Zn anode stability. The VSSE is created by nano‐SiO2 inducing a liquid‐to‐solid transition in a liquid solution containing Zn(BF4)2 salt dissolved in an oligomer (glycerol polyoxyethylene‐b‐oxypropylene ether, GPE) and water. The plentiful oxygen functional group in VSSE provides enough hydrogen bonding sites for water molecules to be completely hydrogen‐bonded to form a state without free water. The bound water serves as a Zn‐O coordination modulator that can weaken the strong Zn‐O coordination, lowering the dissociation energy for Zn ions, realizing fast Zn ion decoupling motion mode. Consequently, the VSSE gives impressive Zn ion conductance of (2.28 ± 0.07) ×10−3 S cm−1 at room temperature 10–1000 times higher than reported solid polymer electrolytes. Simultaneously, the restricted molecular activity of bound water allows for excellent storage/cycle life of the Zn metal anode, which is confirmed by remarkably improved storage life (720 h), shelving‐recovery lifespan (850–1200 h), and cycling life (1400–2050 h). This study offers fresh perspectives on multifunctional electrolyte design strategies based on soft‐matter science.

AbstractThe formation of electric dipoles at the buried interface through self‐assembled molecules is crucial for minimizing non‐radiative recombination and improving the efficiency of inverted perovskite solar cells. However, creating dipoles at the upper interface has seldom been reported in the literature, primarily due to the scarcity of suitable n‐type organic passivants, film sensitivity of perovskite, and chemisorption issues. In this study, a novel bimolecular host–guest strategy is proposed utilizing the cavity of crown ether as the host and the ammonia ion as the guest. The ion‐docking phenomenon is thoroughly examined through a comprehensive range of experimental characterizations and theoretical analyses, instilling confidence in the robustness of the findings. These findings demonstrate that the host–guest electrostatic interlocking induces an electric dipole at the perovskite surface, which facilitates electron extraction and prevents hole recombination. As a result, a power conversion efficiency of 25.25% is achieved with minimal photovoltage and non‐radiative recombination losses. The target devices also exhibited superior long‐term stabilities under high humid and high temperature environments.

Published: December 2024

AbstractOxygen electrochemistry, which encompasses the oxygen reduction reaction (ORR) and the oxygen evolution reaction (OER), is of utmost importance in energy‐related reactions such as zinc‐air batteries (ZABs). However, due to their four‐electron transfer process, these reactions are still significantly restricted by sluggish reaction kinetics. Supporting atomically‐dispersed (AD) catalyst or metal nanoparticles (NPs) on nitrogen‐doped carbon (NC) is proven to be an effective strategy for enhancing the performance of oxygen electrocatalysis. Nevertheless, the performance of these types of catalysts still fails to meet the critical requirements for ZABs. Herein, a novel FeADCoNPs@NC, which consists of both AD Fe‐N1 and Fe sites in the Co lattice, is developed. Spectroscopy studies and density functional theory calculations indicate that the Fe site in the Co lattice facilitates the conversion of Co NPs to an amorphous CoOOH, and the Fe‐N1 serves as the main active site for ORR. FeADCoNPs@NC demonstrates remarkable activity for both OER and ORR. When it is used as an air‐electrode for ZABs, it demonstrates a power density of 247.49 mW cm−2. This work presents a simple yet efficient method to enhance oxygen electrochemical performance through the synergy between AD sites and metal NPs.

Published: December 2024

AbstractObjectivesBreast cancer is a leading cause of morbidity and mortality among women worldwide. This study aims to analyze the trends in breast cancer incidence, mortality, and disability‐adjusted life years (DALYs) across different age groups from 1990 to 2021, and to project the mortality rate for the next decade.MethodsGlobal breast cancer data were analyzed, focusing on three distinct age groups: 15–49 years, 50–69 years, and 70+ years. Joinpoint regression analysis was used to identify periods of significant changes in cancer rate trends (joinpoints). Age‐specific annual percent changes (APC) and average annual percent changes (AAPC) were calculated to identify trends over time. Additionally, an autoregressive integrated moving average (ARIMA) model was employed to forecast future mortality rates.ResultsThe overall incidence of breast cancer increased significantly with an AAPC of 1.6% from 1990 to 2021. The highest increase was observed in the 15–49 years age group (AAPC: 1.3%), while the 70+ years age group showed the lowest increase (AAPC: 0.2%). Mortality rates exhibited a complex pattern, with a modest overall increase (AAPC: 0.8%), a slight increase in the 15–49 years age group (AAPC: 0.4%), and decreases in both 50 and 69 years (AAPC: −0.4%) and 70+ years age groups (AAPC: –0.3%). DALY rates increased slightly overall (AAPC: 0.7%), primarily driven by the 15–49 years age group (AAPC: 0.4%), while the older age groups showed a declining trend (AAPC: −0.4%).ConclusionIncidence rates are rising across all age groups, with the highest increase observed among younger women (15–49 years). In contrast, older age groups (50 + years) are experiencing improvements in mortality and DALYs. These findings underscore the need for targeted public health interventions, enhanced screening practices, and ongoing advancements in breast cancer treatment to address the evolving burden of this disease across different age groups.
