Published: October 2022

AbstractStem cells have demonstrated values in diabetic ulcer (DU) treatments. Challenges in this area are focused on enhancing the localized curative effects of stem cells and improving diabetic wound healing efficiently. Herein, a novel living microneedle (MN) patch is presented as a localized delivery system of bioactive platelet derived growth factor D (PDGF‐D) and human adipose‐derived stem cells (ADSCs) for DU wound treatment. Compared with traditional complicated stem cell carriers, the MN patch can keep stem cell viability for ADSCs encapsulation and delivery, and possesses good mechanical strengths to penetrate the local skin wounds noninvasively. It is demonstrated that the delivery ADSCs are with the abilities of angiogenesis promotion during the DU wound healing; while the additive PDGF‐D can contribute significantly to the proliferation of ADSCs, strengthening the cell function of ADSCs and further facilitating the healing processes. Thus, living MN patches accelerate vascularization, tissue regeneration, and collagen deposition in a wounded diabetic mouse model, suggesting their potential application to DU wound healing and other therapeutic applications.

AbstractDesigning well‐defined interfacial chemical bond bridges is an effective strategy to optimize the catalytic activity of metal–organic frameworks (MOFs), but it remains challenging. Herein, a facile in situ growth strategy is reported for the synthesis of tightly connected 2D/2D heterostructures by coupling MXene with CoBDC nanosheets. The multifunctional MXene nanosheets with high conductivity and ideal hydrophilicity as bridging carriers can ensure structural stability and sufficient exposure to active sites. Moreover, the Co–O–Ti bond bridging formed at the interface effectively triggers the charge transfer and modulates the electronic structure of the Co‐active site, which enhances the reaction kinetics. As a result, the optimized CoBDC/MXene exhibits superior hydrogen evolution reaction (HER) activity with low overpotentials of 29, 41, and 76 mV at 10 mA cm−2 in alkaline, acidic, and neutral electrolytes, respectively, which is comparable to commercial Pt/C. Theoretical calculation demonstrates that the interfacial bridging‐induced electron redistribution optimizes the free energy of water dissociation and hydrogen adsorption, resulting in improved hydrogen evolution. This study not only provides a novel electrocatalyst for efficient HER at all pH conditions but also opens up a new avenue for designing highly active catalytic systems.

Published: October 2022

AbstractAs a functional 2D material, black phosphorus (BP) has garnered wide attention from many researchers in recent years. BP has a wide NIR absorption window and is a promising candidate for cancer phototherapy including photothermal therapy (PTT) and photodynamic therapy (PDT). However, due to its rapid degradation and short shelf‐life in conventional water, the application of BP in the field of cancer therapy is limited. Violet phosphorus (VP), the more stable allotrope of phosphorus, has not yet been investigated for its function and biological application. In this study, VP nanosheets are successfully fabricated by liquid‐phase exfoliation and demonstrated that their shelf‐life in deionized water could be as long as 10 days, which is much longer than that of BP. Through in vivo and in vitro experiments, the PDT, PTT, and catalytic therapeutic effects of VP, as well as its excellent biosafety for the first time are shown. VP effectively inhibits tumor growth without causing major side effects. The current study provides new ideas and strategies for the biological application of 2D sheets of phosphorus isotope and lays the foundation for further studies on exploring the biomedical application of phosphorus isotopes.

AbstractThe properties of the conductance at the LaInO3/BaSnO3 heterointerface are reported. The heterointerface is formed by covering the semi‐insulating BaSnO3:La thin films with 10 nm LaInO3 films, which are all epitaxially grown on NdScO3 substrates. Structural properties of BaSnO3 thin films are investigated by means of X‐ray diffraction and transmission electron microscopy and exhibit a threading dislocation density of 6 × 1010 cm−2. Via capacitance–voltage (C–V) measurements, clear evidence is present for the accumulation of electrons at the interface within 2.5 nm in the BaSnO3 layer, confirming the formation of a 2D electron gas (2DEG). Additionally, temperature dependent Hall effect measurements reveal a semiconducting behavior of the electron density of the 2DEGs. The room temperature mobility of 22 cm2 V−1 s−1 at an electron density of 4 × 1013 cm−2 is found to increase as the temperature decreases to 25 K.

AbstractUltrafast laser‐induced dynamics in a ferrimagnetic gadolinium iron cobalt (Gd/FeCo) multilayer with a magnetization compensation temperature of TM = 320 K is studied at room temperature as a function of laser‐fluence and strength of the applied magnetic field. The dynamics is found to be substantially different from that in archetypical GdFeCo alloys, and depending on the laser fluence one can distinguish two different regimes. At low laser fluence (⩽1.6 mJ cm‐2), ultrafast laser excitation of the medium triggers spin precession of an extraordinary large amplitude reaching over 30°. At high laser fluence (⩾2.2 mJ cm‐2), the pump heats the medium over the magnetization compensation point, spin precession reduces significantly in amplitude and the process of field‐assisted reversal of magnetization of Gd and FeCo is launched. It is argued that such a distinctly different laser‐induced magnetization dynamics in the multilayers compared to the alloys is due to the symmetry breaking at the numerous interfaces, giving rise to additional surface anisotropy. The temperature dependence of the latter is found to be the key ingredient in the mechanism of ultrafast laser‐induced magnetization dynamics in ferrimagnetic multilayers. Controlling the amount and properties of interfaces in multilayers can thus serve as a mean to achieve efficient ultrafast all‐optical control of magnetism.

AbstractTopological electronic materials hold great promise for revolutionizing spintronics, owing to their topological protected, spin‐polarized conduction edge or surface state. One of the key bottlenecks for the practical use of common binary and ternary topological insulator materials is the large defect concentration that leads to a high background carrier concentration. Elemental tin in its α‐phase is a room temperature topological semimetal, which is intrinsically less prone to defect‐related shortcomings. Recently, the growth of ultrathin α‐Sn films on ferromagnetic Co surfaces has been achieved; however, thicker films are needed to reach the 3D topological Dirac semimetallic state. Here, the growth of α‐Sn films on Co at cryogenic temperatures was explored. Very low‐temperature growth holds the promise of suppressing undesired phases, alloying across the interfaces, as well as the formation of Sn pillars or hillocks. Nevertheless, the critical Sn layer thickness of ≈3 atomic layers, above which the film partially transforms into the undesired b‐phase, remains the same as for room‐temperature growth. From ferromagnetic resonance studies, and supported by electron microscopy, it can be concluded that for cryogenic Sn layer growth, the interface between Sn and Co remains sharp and the magnetic properties of the Co layer stay intact.

AbstractDeveloping tunable and highly efficient electromagnetic wave (EMW) absorbers with low density is crucial for the development of wireless telecommunications devices in extreme conditions. SiC ceramic has received much attention because of its dielectric tenability, low density, and chemical stability. However, the present SiC‐based materials usually show limited EMW absorbing performance than they are expected. Herein, an ultralight and resilient bicontinuous Si3N4/SiC network (8 mg cm−3) composed of EMW‐transparent Si3N4 microbelts and EMW‐absorption SiC nanowires is designed and prepared to achieve improved impedance matching and EMW attenuation capacity. The optimized bicontinuous network exhibits a broad effective absorption bandwidth of 8.62 GHz and a strong RLmin of −52.31 dB. Furthermore, the resulting bicontinuous Si3N4/SiC network, with thickness of 6 mm, shows a tunable absorption bandwidth ranging from 5.36 to 18 GHz by resilient action. It also exhibits excellent thermal stability (up to 1000 °C), thermal shock resistance (from −196 to 900 °C), and thermal insulation performance (32 Mw m−1 K−1), enabling it to be an ideal candidate for EMW absorption in extreme environments.

AbstractFunctionalization of ligated metal nanoclusters with versatile ligands is highly desired for wide applications. Lewis acids have shown promise in multiple realms such as self‐assembly and catalysis, which may endow nanoclusters with diverse functions. However, metal nanoclusters with Lewis acid surface have not been reported. Here, the functionalization of a bimetallic nanocluster Au8Ag8(CCR)16 with triarylborane (TAB) is reported, which exhibits enhanced Lewis acidity. By using single‐crystal X‐ray crystallography, the structure of the nanocluster with 16 boron receptor sites is confirmed, which presents ≈15‐fold enhancement of quenching efficiency in sensing fluoride compared to that of free triarylborane ligand. By the combined analysis using ultrafast transient absorption and photoluminescent (PL) decay measurements, the quenching mechanism of Au8Ag8 to fluoride is elucidated. The PL quenching is realized via two pathways with enhanced non‐radiation energy dissipation, i.e., prolonged electron–phonon coupling and reverse intersystem crossing (RISC). This work may open a new route to diverse applications of metal nanoclusters.
Switching Behavior of Dip‐Coated Organic Ferroelectric Trialkylbenzene‐1,3,5‐tricarboxamide (BTA)

Published: October 2022

AbstractSupramolecular organic ferroelectrics have unique properties related to plasticity and freedom of design but the extensive post‐deposition treatments that are typically required to achieve saturation polarization limit their applicability. A possible solution is to pre‐align the molecules. Here, the effect of dip‐coating on the pre‐alignment of the prototypical supramolecular ferroelectric trialkylbenzene‐1,3,5‐tricarboxamide (BTA) and the resulting changes in the ferroelectric switching behavior of the resulting thin films are analyzed. Dip‐coated films are characterized by different BTA concentrations and dip‐coating velocities. Landau–Levich and evaporation regimes are identified. The corresponding ferroelectric switching behavior is investigated and reveals that dip‐coating in general enhances the ferroelectric switching of pristine films. Dip‐coating perpendicular to the electrodes (parallel to the electric field direction) has the most significant effect, and without further alignment steps, leads to equal switching behavior as films that are aligned by post‐deposition treatment, that is, field annealing. The results are expected to be transferable to other small molecular ferroelectrics.

Published: October 2022

AbstractOral drug administration provides a convenient and patient‐compliant way for drug delivery, especially for chronic diseases and prolonged pharmacological treatments. However, due to the repetitiveness of such therapeutic approach, the patients are led to neglect/forget the therapy affecting the healthcare delivery. Indeed, the non‐adherence to pharmacological prescriptions and the unknown amount of real‐time drug release result in a non‐compliant therapeutic drug level over the protracted therapies. The proposed technology will enable the monitoring of both pharmacological adherence and real‐time drug release. The approach exploits a passive intrabody communication (IBC) activation in order to enable an edible pill, realized starting from food additives and food‐grade materials, to monitor pharmacological adherence. Following activation, the signal is modulated by IBC coupling switching triggered by pill degradation in a gastrointestinal tract, resulting in a monitored drug release. The proof‐of‐concept is designed for a targeted release and monitoring of Metformin in the intestine. The system shows an in vitro limit of cumulative drug release detection of 18 µg mL−1 and a limit of real‐time drug release detection of 2 µg mL−1 min−1. This platform represents the first solution to monitor passive drug release in real‐time, from intake to complete absorption, enabling unique and long‐sought healthcare therapy and treatment opportunity.

AbstractPrintable oxide transistors have emerged as important optoelectronic synaptic devices to emulate the human visual cognitive system by integrating both photo‐sensing and visual perception functions. However, the inferior electrical performance and low pixel density of printed oxide synaptic transistors impede their implementation of complex neuromorphic computing. Herein, a printable all‐oxide optoelectronic synaptic transistor array based on a modified coffee‐ring structure of indium tin oxide (ITO) is reported. The extraordinary structural design endows the printed ITO transistors with high device uniformity, outstanding electrical performance, and superior process efficiency. Furthermore, a 10 × 12 coffee‐ring structure optoelectronic synaptic transistor array with a high spatial resolution (142 dpi) exhibits durable visual detection and memory behaviors. Meanwhile, an artificial neural network based on the coffee‐ring structure synaptic transistors exhibits high accuracy in the recognition rate. These results promise the efficiency of the exceptional printing strategy in developing advanced optoelectronic synaptic transistors for artificial visual systems.

AbstractNear‐infrared phosphor‐converted light‐emitting diodes (NIR pc‐LEDs) have promising applications in food analysis, night vision imaging, and biological probes. Developing NIR phosphors with broadband emission and high efficiency has attracted immense interest. Herein, a novel NIR phosphor Ca2LuScAl2Si2O12:Cr3+ (CLSAS:Cr3+) is reported for the first time. Under the excitation of 442 nm light, CLSAS:Cr3+ shows broadband emission from 600 to 900 nm with a full width at half maximum (FWHM) of 142 nm, benefiting from the emissions of two Cr3+ centers in CLSAS, which is proved by the spectra and the decay curves. The internal quantum efficiency (IQE) of 73.7% is achieved and, at 423 K, the emission intensity maintains 76% of the value at room temperature. Combining the CLSAS:Cr3+ phosphor and the 450 nm blue chip, the NIR pc‐LED is fabricated and demonstrated for fast imaging of veins in human palm and fist, as well as night vision for objects.

AbstractHeat is abundantly available from various sources including solar irradiation, geothermal energy, industrial processes, automobile exhausts, and from the human body and other living beings. However, these heat sources are often overlooked despite their abundance, and their potential applications remain underdeveloped. In recent years, important progress has been made in the development of high‐performance thermoelectric materials, which have been extensively studied at medium and high temperatures, but less so at near room temperature. Silver‐based chalcogenides have gained much attention as near room temperature thermoelectric materials, and they are anticipated to catalyze tremendous growth in energy harvesting for advancing internet of things appliances, self‐powered wearable medical systems, and self‐powered wearable intelligent devices. This review encompasses the recent advancements of thermoelectric silver‐based chalcogenides including binary and multinary compounds, as well as their hybrids and composites. Emphasis is placed on strategic approaches which improve the value of the figure of merit for better thermoelectric performance at near room temperature via engineering material size, shape, composition, bandgap, etc. This review also describes the potential of thermoelectric materials for applications including self‐powering wearable devices created by different approaches. Lastly, the underlying challenges and perspectives on the future development of thermoelectric materials are discussed.

AbstractThe development of low‐cost, high‐efficiency, and stable electrocatalysts for hydrogen evolution reaction (HER) under alkaline conditions is a key challenge in water electrolysis. Here, an interfacial engineering strategy that is capable of simultaneously regulating nanoscale structure, electronic structure, and interfacial structure of Mo2N quantum dots decorated on conductive N‐doped graphene via codoping single‐atom Al and O (denoted as AlO@Mo2N‐NrGO) is reported. The conversion of Anderson polyoxometalates anion cluster ([AlMo6O24H6]3−, denoted as AlMo6) to Mo2N quantum dots not only result in the generation of more exposed active sites but also in situ codoping atomically dispersed Al and O, that can fine‐tune the electronic structure of Mo2N. It is also identified that the surface reconstruction of AlOH hydrates in AlO@Mo2N quantum dots plays an essential role in enhancing hydrophilicity and lowering the energy barriers for water dissociation and hydrogen desorption, resulting in a remarkable alkaline HER performance, even better than the commercial 20% Pt/C. Moreover, the strong interfacial interaction (MoN bonds) between AlO@Mo2N and N‐doped graphene can significantly improve electron transfer efficiency and interfacial stability. As a result, outstanding stability over 300 h at a current density higher than 100 mA cm−2 is achieved, demonstrating great potential for the practical application of this catalyst.

AbstractWe replicate Bocquého et al. (2014), who used multiple price lists to investigate the risk preferences of 107 French farmers. We collected new data from 1430 participants in 11 European farming systems. In agreement with the original study, farmers' risk preferences are best described by Cumulative Prospect Theory. Structural model estimates show that farmers in the new samples are, on average, less loss averse and more susceptible to probability distortion than in the original study. Explorative analyses indicate differences between estimation approaches, as well as heterogeneity between and within samples. We discuss challenges in replications of economic experiments with farmers across farming contexts.

AbstractInforming parents that their child has a diagnosis of Down syndrome (DS) is a common example of the delivery of unexpected or difficult news. Expectations and life planning will change, and if detected prenatally, discussions might include the option of pregnancy termination. Medical school curricula currently include training in breaking unexpected news; however, it is difficult to teach and assess. We use the perspectives of clinicians, educators, and a medical student who is the parent of a child with DS to frame a discussion on teaching, practicing, and assessing communication of difficult news in human genetics during medical school.
