AbstractComplementary metal‐oxide‐semiconductor (CMOS) field‐effect transistors (FETs) are the key component of a chip. Bulk indium arsenide (InAs) owns nearly 30 times higher electron mobilityµethan silicon but suffers from a much lower hole mobilityµh(µe/µh = 80), thus unsuited to CMOS application with a single material. Through the accurate ab initio quantum‐transport simulations, the performance gap between the NMOS and PMOS is significantly narrowed is predicted and even vanished in the sub‐2‐nm‐diameter gate‐all‐around (GAA) InAs nanowires (NW) FETs because the inversion of the light and heavy hole bands occurs when the diameter is shorter than 3 nm. It is further proposed several feasible strategies for further improving the performance symmetry in the GAA InAs NWFETs. Short‐channel effects are effectively depressed in the symmetricn‐ andp‐type GAA InAs NWFETs till the gate length is scaled down to 2 nm according to the standards of the International Technology Roadmap for Semiconductors. Therefore, the ultrasmall GAA InAs NWFETs possess tremendous prospects in CMOS integrated circuits.

AbstractMixed transition metal oxides are promising anodes to meet high‐performance energy storage materials; however, their widespread uses are restrained owing to limited theoretical capacity, restricted synthesis methods and templates, low conductivity, and extreme volume expansion. Here, Mn3‐xFexO4 nanosheets with interconnected conductive networks are synthesized via a novel self‐hybridization approach of a facile, galvanic replacement‐derived, tetraethyl orthosilicate‐assisted hydrothermal process. An exceptionally high reversible capacity of 1492.9 mAh g−1 at 0.1 A g−1 is achieved by producing Li‐rich phase through combined synergistic effects of amorphous phases with interface modification design for fully utilizing highly spin‐polarized surface capacitance. Furthermore, it is demonstrated that large surface area can effectively facilitate Li‐ion kinetics, and the formation of interconnected conductive networks improves the electrical conductivity and structural stability by alleviating volume expansion. This leads to a high rate capability of 412.3 mAh g−1 even at an extremely high current density of 10 A g−1 and stable cyclic stability with a capacity up to 921.9 mAh g−1 at 2 A g−1 after 500 cycles. This study can help to overcome theoretically limited electrochemical properties of conventional metal oxide materials, providing a new insight into the rational design with surface alteration to boost Li‐ion storage capacity.

Published: February 2023

AbstractImitating mechano‐sensing luminescence of organisms has long been envisaged to achieve dynamic and real‐time visualized information display, however, it remains challenging to recreate the skin‐like visual sensation functions in artificial sensors. Here, a bioinspired mechanosensor is presented with mechanoluminescent/triboelectric hierarchical structure that is capable of pressure perception and patterning display in real time. Interestingly, a facilitative effect of interfacial triboelectric field on luminescent output and pressure visualization was found. The developed mechanosensor shows self‐powered, bimodal, and real‐time patterning sensation behavior with a low force detection limit (0.082 N), high sensitivity (9.69 a.u. N−1), fast response (35 ms), and good reliability (5000 cycles). On this basis, an intelligent control system is further constructed via combining image machine learning approach. This study not only addresses the long‐lasting challenge of real‐time pressure visualized display, but also boosts the further development of untethered, small‐scale, and efficient intelligent systems.

AbstractOsteoarthritis is a degenerative disorder that can severely affect joints, and new treatment strategies are urgently needed. Administration of mesenchymal stem cell (MSC)‐derived exosomes is a promising therapeutic strategy in osteoarthritis treatment. However, the poor yield of exosomes is an obstacle to the use of this modality in the clinic. Herein, a promising strategy is developed to fabricate high‐yield exosome‐mimicking MSC‐derived nanovesicles (MSC‐NVs) with enhanced regenerative and anti‐inflammatory capabilities. MSC‐NVs are prepared using an extrusion approach and are found to increase chondrocyte and human bone marrow MSC differentiation, proliferation, and migration, in addition to inducing M2 macrophage polarization. Furthermore, gelatin methacryloyl (GelMA) hydrogels loaded with MSC‐NVs (GelMA‐NVs) are formulated, which exhibit sustained release of MSC‐NVs and are shown to be biocompatible with excellent mechanical properties. In a mouse osteoarthritis model constructed by surgical destabilization of the medial meniscus (DMM), GelMA‐NVs effectively ameliorate osteoarthritis severity, reduce the secretion of catabolic factors, and enhance matrix synthesis. Furthermore, GelMA‐NVs induce M2 macrophage polarization and inflammatory response inhibition in vivo. The findings demonstrate that GelMA‐NVs hold promise for osteoarthritis treatment through modulation of chondrogenesis and macrophage polarization.

Published: February 2023

AbstractCurrent thermochromic materials used in smart windows still face challenges, such as poor mechanical and environmental stability, unsatisfactory solar modulation capacity, and low transparency. Herein, the first self‐adhesive self‐healing thermochromic ionogels with excellent mechanical and environmental stability, antifogging capability, transparency, and solar modulation capability by loading binary ionic liquids (ILs) into rational‐designed self‐healing poly(urethaneurea) with acylsemicarbazide (ASCZ) moieties that have reversible and multiple hydrogen bonds are reported and their feasibility as smart windows with reliability and long service life is demonstrated. The self‐healing thermochromic ionogels can switch between transparent and opaque without leakage or shrinkage, by the constrained reversible phase separation of ILs within the ionogels. The ionogels have the highest transparency and solar modulation capability among reported thermochromic materials and such excellent solar modulation capability can be well maintained after undergoing 1000 transitions, stretches, and bends, and storage at −30 °C, 60 °C, 90% RH, and vacuum environment for 2 months. The formation of high‐density hydrogen bonds among the ASCZ moieties contributes to the excellent mechanical strength of the ionogels and allows the thermochromic ionogels to spontaneously heal their damages and be fully recycled at room temperature without the loss of thermochromic capabilities.

Published: February 2023

AbstractContinuously graded parabolic quantum wells with excellent optical performances are used to overcome the low‐frequency and thermal limitations of square quantum wells at terahertz (THz) frequencies. The formation of microcavity intersubband polaritons at frequencies as low as 1.8 THz is demonstrated, with a sustained ultra‐strong coupling regime up to a temperature of 200 K. Thanks to the excellent intersubband transition linewidth, polaritons present quality factors up to 17. It is additionally shown that the ultra‐strong coupling regime is preserved when the active region is embedded in sub‐wavelength resonators, with an estimated relative strength η = ΩR/ω0 = 0.12. This represents an important milestone for future studies of quantum vacuum radiation because such resonators can be optically modulated at ultrafast rates, possibly leading to the generation of non‐classical light via the dynamic Casimir effect. Finally, with an effective volume of , it is estimated that fewer than 3000 electrons per resonator are ultra‐strongly coupled to the quantized electromagnetic mode, proving it is also a promising approach to explore few‐electron polaritonic systems operating at relatively high temperatures.

AbstractGraphene has attracted great interest for integrated photonic platforms in the long‐wave infrared (LWIR) for spectroscopic and polarimetric sensing due to the capability of on‐chip integration, fast response, and broadband operation. However, graphene suffers from low photoresponsivity and thus poor sensing performance due to weak absorption. Polarization detection using graphene is hindered by its small in‐plane anisotropy. Here, nanoantenna‐mediated graphene photodetectors (NMGPDs) are proposed to enhance responsivity by tailoring the nanoantenna near‐field distribution to generate a strong photoresponse. The devices demonstrate a high responsivity of 6.3 V W−1 under zero bias at room temperature with low noise‐equivalent power of 1.6 nW Hz−1/2. Furthermore, polarization detection is enabled by artificial near‐field anisotropy enabled by double L‐shaped nanoantennas. The proposed LWIR NMGPDs achieve subtle polarization‐angle detection down to 0.05° thanks to the unusual negative polarization ratio of −1. To demonstrate the advances of LWIR NMGPDs for molecule detection, acetone is chosen as an analyte for spectroscopic sensing. The devices show a low limit of detection of 115 ppm, and fast dynamic gas sensing response of 6 s for real‐time monitoring. These results reveal the potential of the device as a multi‐functional on‐chip miniaturized optoelectronic platform for polarimetric and spectroscopic sensing toward real‐time environmental monitoring and biomedical screening.
Enhanced Ultra‐Long Room Temperature Phosphorescence by Intermolecular Donor–Acceptor Interaction in Polymer Network

Published: February 2023

AbstractUltra‐long room temperature phosphorescence (URTP) is an attractive phenomenon in organic photonics. However, most of the reported strategies for enhancing URTP require complicated synthesis processes. Herein, a novel strategy is reported, two birds with one stone, for enhancing URTP by doping the ground‐state intermolecular donor–acceptor complexes into a dense polymer network: i) The dense network ensures the formation of intermolecular donor–acceptor complexes, which provide a smaller singlet‐triplet energy difference (ΔEST) and more intersystem crossing (ISC) channels than the individual donor or acceptor molecules; ii) The dense network adequately suppresses the non‐radiative relaxation caused by molecular vibrations and oxygen quenching. The URTP intensities of the intermolecular donor–acceptor complexes doped film are 20 times higher than that of the film only doped with acceptor molecules, and the phosphorescence lifetime is up to 200 ms. The theoretical calculation reveals the electronic interaction between donor and acceptor and the increased ISC channel, which elucidates the photophysical mechanism of the strategy and confirms its rationality. An advanced encryption application is developed based on enhanced URTP films. This work opens a new direction for URTP materials through the intermolecular donor–acceptor interaction.

AbstractDirect measurements of the electric field of light enable new observations of light–matter interactions. In the near‐infrared and visible spectral ranges, this typically relies on techniques that exploit nonlinearities in gases or solids, which limits their sensitivity. Here, a method for the detection of broadband near‐infrared fields spanning more than one octave from 110 to 220 THz based on linear absorption in a semiconductor is demonstrated. This technique, which avoids complex vacuum setups and works under ambient conditions, employs linear photoconductive sampling (LPS) in gallium phosphide. Simulations reveal that the response function of LPS is concerned with the intensity envelope of the gate field, in contrast to electro‐optic sampling, relaxing the stringent temporal requirements on the gate pulse.

Published: February 2023

AbstractNovel coronary Au@Bi nanospheres (NSs) are simply synthesized by sparkling gold nanoparticles (Au NPs) on the surface of bismuth (Bi) NSs and successfully used as highly impedance‐sensitive immunosensing platform to develop a new label‐free electrochemical immunosensor for the detection of carcinoembryonic antigen (CEA). Firstly, Bi NSs are prepared by one‐pot hydrothermal method, showing uniform sphere morphology with a dense oxide film formed outside Bi NSs due to the easy oxidation of Bi in the air. The oxide film significantly hinders the transmission of electrons and effectively improves the sensitivity of the proposed electrochemical impedance immunosensor. The surface functionalization of Bi NSs with Au NPs enhances the biocompatibility, stability, as well as active surface area of the produced Au@Bi NSs, preferable for the efficient loading of antibody molecules. The electrochemical impedance spectroscopy (EIS) is selected as the optical technique to measure CEA with the constructed immunosensor based on Au@Bi NSs. Because of the excellent impedance‐responsive performance, this new immunosensor displays highly sensitive detection toward CEA in a linear range of 50 fg mL−1–100 ng mL−1 with an extremely low detection limit of 9.83 fg mL−1 and could be potentially used in early clinical detection of cancer.

Published: February 2023

AbstractWith the threat posed by drug‐resistant pathogenic bacteria, developing non‐antibiotic strategies for eradicating clinically prevalent superbugs remains challenging. Ferroptosis is a newly discovered form of regulated cell death that can overcome drug resistance. Emerging evidence shows the potential of triggering ferroptosis‐like for antibacterial therapy, but the direct delivery of iron species is inefficient and may cause detrimental effects. Herein, an effective strategy to induce bacterial nonferrous ferroptosis‐like by coordinating single‐atom metal sites (e.g., Ir and Ru) into the sp2‐carbon‐linked covalent organic framework (sp2c‐COF‐Ir‐ppy2and sp2c‐COF‐Ru‐bpy2) is reported. Upon activating by light irradiation or hydrogen peroxide, the as‐constructed Ir and Ru single‐atom catalysts (SACs) can significantly expedite intracellular reactive oxygen species burst, enhance glutathione depletion‐related glutathione peroxidase 4 deactivation, and disturb the nitrogen and respiratory metabolisms, leading to lipid peroxidation‐driven ferroptotic damage. Both SAC inducers show potent antibacterial activity against Gram‐positive bacteria, Gram‐negative bacteria, clinically isolated methicillin‐resistantStaphylococcus aureus(MRSA), and biofilms, as well as excellent biocompatibility and strong therapeutic and preventive potential in MRSA‐infected wounds and abscesses. This delicate nonferrous ferroptosis‐like strategy may open up new insights into the therapy of drug‐resistant pathogen infection.

AbstractThe discovery of the medicinal properties of gold complexes has fuelled the design and synthesis of new anticancer metallodrugs, which have received special attention due to their unique modes of action. Current research in the development of gold compounds with therapeutic properties is predominantly focused on the molecular design of drug leads with superior pharmacological activities, e.g., by introducing targeting features. Moreover, intensive research aims at improving the physicochemical properties of gold compounds, such as chemical stability and solubility in the physiological environment. In this regard, the encapsulation of gold compounds in nanocarriers or their chemical grafting onto targeted delivery vectors could lead to new nanomedicines that eventually reach clinical applications. Herein, we provide an overview of the state‐of‐the‐art progress of gold anticancer compounds, andmore importantly we thoroughly revise the development of nanoparticle‐based delivery systems for gold chemotherapeutics.

AbstractDie Flüssig‐Flüssig‐Phasentrennung hat sich als grundlegender Prozess bei der Bildung biomolekularer Kondensate erwiesen. Einblicke in die Zusammensetzung und Struktur biomolekularer Kondensate werden jedoch durch deren molekulare Komplexität und Dynamik erschwert. Hier stellen wir ein verbessertes räumlich aufgelöstes NMR‐Experiment vor, das eine quantitative Analyse der physikalisch‐chemischen Zusammensetzung von biomolekularen Mehrkomponenten‐Kondensaten im Gleichgewicht und ohne Markierung ermöglicht. Die Anwendung der ortsaufgelösten NMR auf Kondensate, die durch das mit der Alzheimer‐Krankheit assoziierte Protein Tau gebildet werden, zeigt einen verringerten Wassergehalt, den Ausschluss des molekularen Verdrängungsmittels Dextran, das Vorhandensein einer spezifischen chemischen Umgebung des kleinen Moleküls DSS und eine ≈150‐fach erhöhte Konzentration von Tau im Kondensat. Die Ergebnisse deuten darauf hin, dass die ortsaufgelöste NMR einen großen Einfluss auf das Verständnis der Zusammensetzung und der physikalischen Chemie von biomolekularen Kondensaten haben kann.

Published: February 2023

AbstractKey challenges in modern synthetic chemistry include the design of reliable, selective, and more sustainable synthetic methods, as well as the development of promising candidates for new materials. Molecular bismuth compounds offer valuable opportunities as they show an intriguing spectrum of properties that is yet to be fully exploited: a soft character, a rich coordination chemistry, the availability of a broad variety of oxidation states (at least +V to −I) and formal charges (at least +3 to −3) at the Bi atoms, and reversible switching between multiple oxidation states. All this is paired with the status of a non‐precious (semi−)metal of good availability and a tendency towards low toxicity. Recent findings show that some of these properties only come into reach, or can be substantially optimized, when charged compounds are specifically addressed. In this review, essential contributions to the synthesis, analyses, and utilization of ionic bismuth compounds are highlighted.

Published: February 2023

AbstractAlthough the direct conversion of gaseous acetylene into value‐added liquid commodity chemicals is becoming increasingly attractive, the majority of the established methodologies are focused on cross‐coupling, hydro‐functionalization, and polymerization. Herein, we describe a 1,2‐difunctionalization method that inserts acetylene directly into readily available bifunctional reagents. This method provides access to diverse C2‐linked 1,2‐bis‐heteroatom products in high regio‐ and stereoselectivity along with opening up previously unexplored synthetic directions. In addition, we demonstrate this method's synthetic potential by converting the obtained products into diverse functionalized molecules and chiral sulfoxide‐containing bidentate ligands. Using a combination of experimental and theoretical methods, the mechanism for this insertion reaction was investigated.

Published: February 2023

AbstractAqueous copper metal batteries with acidic electrolytes are regarded as promising candidates for low‐temperature energy storage, benefiting from fast kinetics of protons and acid resistance of copper. Here, a Cu(BF4)2 electrolyte that spontaneously generates protons is developed for ultralow‐temperature copper metal batteries. Systematic studies demonstrate that the hydrolysis of BF4− generates more protons, rendering the Cu(BF4)2 among the most effective aqueous electrolyte capable of breaking hydrogen bonds in water molecules. This electrolyte endows a polyaniline/Cu battery to deliver a short charging time of 21 s and a charge/discharge capability of up to 10 A g−1 at −30 °C, along with a high discharge specific capacity of 70 mAh g−1 and a supercapacitor‐comparable power density of 3000 W kg−1. Furthermore, it can exhibit a long and stable cycling lifespan over 10 000 cycles at −50 °C and works well at −70 °C. This work provides an opportunity for intrinsically acidic electrolytes.
