Published: January 2024

AbstractViolet phosphorus (VP) is garnering attention for its appealing physical properties and potential applications in optoelectronics. A comprehensive investigation of the photodegradation and thermal effects of exfoliated VP on SiO2/Si substrates is presented. The degradation rate of VP is strongly influenced by the wavelength and exposure duration of light. Light illumination of VP above the bandgap leads to faster degradation, attributed to interactions with reactive oxygen species. Power‐dependent photoluminescence (PL) measurements at low temperature (T = 4 K) show neutral exciton (X0) and trion (T) intensities linearly increase with excitation power, while the energy difference between peak energies decreases. The T/X0 spectral weight ratio increases from 0.28 at 300 K to 0.69 at 4 K, suggesting enhanced T formation due to reduced phonon scattering. Temperature‐dependent Raman is used to investigate the phonon properties of VP. Tracking peak positions of 9 Raman modes with temperature, the linear first‐order temperature coefficient is obtained and found to be linear for all modes. The results provide a deeper understanding of VP's degradation behavior and implications for optoelectronic applications.

AbstractA novel additive manufacturing route using a tailored resin containing Poly(vinylidene fluoride) Trifluoroethylene (PVDF‐TrFE) to 3D print piezoelectric films is demonstrated. Piezoelectric films are printed within 2 seconds in a single step by simultaneously focusing initiating and inhibiting excitations within the liquid resin to locally confine the photochemical reaction. The printed films are patterned with an array of holes with a diameter of 30 µm and a pitch of 55 µm. The piezoelectric response is homogeneous across the film, indicating that the print pattern does not impact the PVDF‐TrFE microstructure. Although the printed films contain only a small volume fraction of PVDF‐TrFE (3 wt.%), their piezoelectric response (d33 = 20.3 pC/N) is comparable to the highest literature values reported for PVDF‐TrFE films. The printed PVDF‐TrFE films are predominantly β‐phase, and no electrical poling, post‐processing, piezoelectric or inorganic additives are used in the fabrication. Analysis using piezoresponse force microscopy (PFM) and scanning electron microscopy (SEM) reveals that the enhanced piezoelectric response is due to the preferential formation of oriented PVDF‐TrFE phases during printing. These results demonstrate how the dedicated design of photoactive resins in combination with volumetric additive manufacturing can be applied to rapidly fabricate functional 3D structures.

AbstractWith the rapid development of industry and information technology, rough challenges have been put forward for the traditional sensor technology to meet the increasingly complex and diverse application demands in actual production and daily life, and the widely distributed sensor network also faces complex power supply and maintenance problems. As a new energy conversion technology, triboelectric nanogenerators (TENGs) based on triboelectrification and electrostatic induction effect can respond to the weak mechanical stimuli in the surrounding environment and generate corresponding electrical signals to realize the sensing function without external power supply. In addition, TENGs have the advantages of wide selection of fabrication materials, flexible and diverse fundamental modes, which can be customized for different applications and realize different sensing functions. In recent years, triboelectric sensors based on TENGs have developed rapidly, and researchers have developed variable triboelectric sensors for different application scenarios. In this paper, the developed triboelectric sensos have been classified into different categories, the advanced strategy to prepare advanced triboelectric materials and technology used for manufacturing integration have been introduced. This work summarizes the main applications of triboelectric sensors and put forward the current challenges, so as to provide guidance and instructions for the future development of triboelectric sensors.

Published: January 2024

AbstractThis paper designs and validates a composite functional metasurface that combines microwave absorption and vibrational energy harvesting. The metasurface is composed of an indium tin oxide (ITO) electrically conductive glass pattern layer, arrays of 1‐ethyl‐3‐methylimidazolium dicyanamide [EMIM][N(CN)2] droplets, and an underlying indium tin oxide (ITO) electrically conductive glass layer. The composite functional metasurface possesses broadband absorption performance when the microwave frequency bands are between 7.34 and 22.63 GHz, which can transform vibration energy into electrical energy simultaneously. The relationship between output power, the number of droplets, internal resistance, and the matching load of the composite functional metasurface is deeply studied. It is found that the internal resistance decreases with the increase in the number of droplet arrays. The effective output power reaches up to 125nW when there are 48 droplet arrays. This technology has promising applications in the field of intelligent and portable electromagnetic devices.

Published: January 2024

AbstractPancreatic ductal adenocarcinoma (PDAC) is a deadly cancer that can develop from pancreatic intraepithelial neoplasia (PanIN), a microscopic lesion in the pancreatic ductal system. PanIN and PDAC are conventionally studied in 2D via histological tissue sections. As such, their true structure is poorly understood due to the inability to image them in 3D. CODA, a recently developed technique for reconstruction of tissues at cellular resolution, is used to study the 3D morphology of the pancreas. Here, CODA is extended through 3D printing of normal pancreatic ducts, PanIN, and PDAC at cm‐scale and µm resolution. A methodology is presented to create 3D printable files from anatomical maps generated from serial histological images and to show detailed validation of the accuracy of this method. Existing 3D printing workflows utilizing medical images derived from computerized tomography (CT), X‐ray, and magnetic resonance imaging (MRI) are scientifically proven to be useful in printing whole organ‐scale structures with sub‐mm resolution. Here, using serial histological sections, it is demonstrated that 3D printing of higher‐resolution structures is also possible. Finally, with the 3D models of normal ducts, PanIN, and PDAC, marked changes to the structure of the human pancreas during tumorigenesis are revealed.

AbstractConsidering environmental changes and the demand for more sustainable energy sources, stricter requirements have been placed on electrode materials for sodium and potassium‐ion batteries, which are expected to provide higher energy and power density while being affordable and sustainable. Vanadium sulfide‐based materials have emerged as intriguing contenders for the next generation of anode materials due to their high theoretical capacity, abundant reserves, and cost‐effectiveness. Despite these advantages, challenges such as limited cycle life and restricted ion diffusion coefficients continue to impede their effective application in sodium and potassium‐ion batteries. To overcome the limitations associated with electrochemical performance and circumvent bottlenecks imposed by the inherent properties of materials at the bulk scale, this review comprehensively summarizes and analyzes the crystal structures, modification strategies, and energy storage processes of vanadium sulfide‐based electrode materials for sodium and potassium‐ion batteries. The objective is to guide the development of high‐performance vanadium‐based sulfide electrode materials with refined morphologies and/or structures, employing environmentally friendly and cost‐efficient methods. Finally, future perspectives and research suggestions for vanadium sulfide‐based materials are presented to propel practical applications forward.

AbstractThe persistent photocurrent (PPC) and high carrier concentration are challenging the ultraviolet photodetection behaviors of amorphous InGaO films. Herein, InGaO/PbI2 heterojunction is constructed by an all‐solution synthesis process to set up a built‐in electric field at the heterojunction interface, which is aimed at the inhibition of PPC, suppression of dark current, and promotion of photogenerated carrier separation. With an optimized In content of 90%, the as‐fabricated InGaO/PbI2 heterojunction photodetector exhibits excellent self‐powered near‐ultraviolet photodetection behaviors with high Ilight/Idark ratio of 104, ultralow dark current of 10−13 A and fast response times of 0.8/0.6 ms. Additionally, benefiting to the all‐solution synthesis process and amorphous characteristic, InGaO/PbI2 heterojunction can be implanted onto any useful substrates to achieve the specific function of photodetection. The as‐fabricated InGaO/PbI2 heterojunction flexible self‐powered photodetector exhibits outstanding mechanical flexibility, bending endurance, and photoelectric stability. When the InGaO/PbI2 heterojunction is implanted onto the transparent substrate, it demonstrates excellent omnidirectional self‐powdered photodetection performance and imaging capability. All results promise all‐solution‐processed InGaO for next‐generation advanced optoelectronics.

AbstractCommercial photosensitizers (PSs) present great potential in the field of clinical photodynamic therapy (PDT) yet face a formidable challenge owing to the extremely short lifespan of singlet oxygen (1O2). Herein, the 1O2 slow‐release “platform” is proposed based on an anthracene‐groups functionalized D‐π‐A system (AIC), which can capture and slowly release 1O2 produced by commercial PSs. Meanwhile, the reversible chemical process between AIC and 1O2 is demonstrated by a series of optical experiments and high‐resolution mass spectrum. Remarkably, by virtue of 1O2 slow‐release “platform”, the sustaining mitochondrial autophagy and cell apoptosis still take place when the laser is cut off with a short period of irradiation, reducing the side effect of sustained irradiation. In general, the construction of 1O2 slow‐release platform opens up exciting opportunities for improving the PDT effect of commercial PSs.

AbstractEnergy sources play a crucial role in the development of the society. The gargantuan depletion of fossil fuels creates new glitches in the routine activities of human beings. Electrocatalysts can efficiently produce and store energy and, therefore, have the potential to alleviate this situation. A multifunctional electrocatalyst, Poly (3,4‐ethylenedioxythiophene)/cobalt oxide‐cerium oxide(PEDOT/Co3O4‐CeO2), is synthesized by incorporating mixed metal oxide to 3,4‐ethylenedioxythiophene (EDOT) using the in situ chemical oxidative polymerization method and is employed for both energy production and storage applications. The successful synthesis of the catalyst is confirmed through various characterization techniques. The composite shows a specific capacity of 617.8 C g−1 and a specific capacitance value of 1298.1 F g−1. The hydrogen evolution reaction (HER) analysis shows that the composite requires a low overpotential of 163.1 mV at a current density of 10 mA cm−2. Synthesized electrocatalysts can effectively handle the energy related issues prevailing in the society.
Surface Aerophilicity Engineering of Heterogeneous Catalysts for Enhanced Catalytic Ozonation

Published: January 2024

AbstractHeterogeneous catalysts for catalytic ozonation are elaborately designed with commendable intrinsic activity, while their industrial applications are limited by inadequate mass transfer of ozone (O3). In this work, it is demonstrated that engineering the surface aerophilicity of heterogeneous catalyst enables fast mass transfer of O3 reactant, giving rise to much enhanced catalytic ozonation performance. Taking active 4A zeolite catalyst as an example, the aerophilicity of spherical 4A zeolite can be greatly enhanced by coating polytetrafluoroethylene (PTFE) with low surface energy, and the optimized sample exhibits a 99.5% removal of atrazine (ATZ) within 20 min (corresponding to a k of 0.269 min−1), much better than 4A zeolite without surface aerophilicity engineering (k≈0.156 min−1). The PTFE coating does not change the ozone activation mechanism and degradation pathways for ATZ, further demonstrating that the enhanced ozonation activity is attributed to the enhanced mass transfer process. In addition, the general applicability of this surface aerophilicity and the potential ozonation application for industrial wastewater treatment are both demonstrated.

Published: January 2024

AbstractCost‐effective non‐noble metal‐based catalysts for selective hydrogenation with excellent activity, selectivity, and durability are still the holy grail. Herein, an oxygen‐doped carbon (OC) chainmail encapsulated dilute Cu–Ni alloy is developed by simple pyrolysis of Cu/Ni‐metal–organic framework. The CuNi0.05@OC catalyst displays superior performance for atmospheric pressure transfer hydrogenation of p‐chloronitrobenzene and p‐nitrophenol, and for hydrogenation of furfural, all in water and with exceptional durability. Comprehensive characterizations confirm the close interactions between the diluted Ni sites, the base Cu, and optimized three‐layered graphene chainmail. Theoretical calculations demonstrate that the properly tuned lattice strain and Schottky junction can adjust electron density to facilitate specific adsorption on the active centers, thus enhancing the catalytic activity and selectivity, while the OC shell also offers robust protection. This work provides a simple and environmentally friendly strategy for developing practical heterogeneous catalysts that bring the synergistic effect into play between dilute alloy and functional carbon wrapping.

AbstractStem cell‐derived pancreatic progenitors (SC‐PPs), as an unlimited source of SC‐derived β (SC‐β) cells, offers a robust tool for diabetes treatment in stem cell‐based transplantation, disease modeling, and drug screening. Whereas, PDX1+/NKX6.1+ PPs enhances the subsequent endocrine lineage specification and gives rise to glucose‐responsive SC‐β cells in vivo and in vitro. To identify the regulators that promote induction efficiency and cellular function maturation, single‐cell RNA‐sequencing is performed to decipher the transcriptional landscape during PPs differentiation. The comprehensive evaluation of functionality demonstrated that manipulating LINC MIR503HG using CRISPR in PP cell fate decision can improve insulin synthesis and secretion in mature SC‐β cells, without effects on liver lineage specification. Importantly, transplantation of MIR503HG−/− SC‐β cells in recipients significantly restored blood glucose homeostasis, accompanied by serum C‐peptide release and an increase in body weight. Mechanistically, by releasing CtBP1 occupying the CDH1 and HES1 promoters, the decrease in MIR503HG expression levels provided an excellent extracellular niche and appropriate Notch signaling activation for PPs following differentiation. Furthermore, this exhibited higher crucial transcription factors and mature epithelial markers in CDH1High expressed clusters. Altogether, these findings highlighted MIR503HG as an essential and exclusive PP cell fate specification regulator with promising therapeutic potential for patients with diabetes.

AbstractThe unprecedented demand for variants diagnosis in response to the COVID‐19 epidemic has brought the spotlight onto rapid and accurate detection assays for single nucleotide polymorphisms (SNPs) at multiple locations. However, it is still challenging to ensure simplicity, affordability, and compatibility with multiplexing. Here, a novel technique is presented that combines peptide nucleic acid (PNA) clamps and near‐infrared (NIR)‐driven digital polymerase chain reaction (dPCR) to identify the Omicron and Delta variants. This is achieved by simultaneously identifying highly conserved mutated signatures at codons 19, 614, and 655 of the spike protein gene. By microfluidically introducing graphene‐oxide‐nanocomposite into the assembled gelatin microcarriers, they achieved a rapid temperature ramping‐up rate and switchable gel‐to‐sol phase transformation synchronized with PCR activation under NIR irradiation. Two sets of duplex PCR reactions, each classifying respective PNA probes, are emulsified in parallel and illuminated together using a homemade vacuum‐based droplet generation device and a programmable NIR control module. This allowed for selective amplification of mutant sequences due to single‐base‐pair mismatch with PNA blockers. Sequence‐recognized bioreactions and fluorescent‐color scoring enabled quick identification of variants. This technique achieved a detection limit of 5,100 copies and a 5‐fold quantitative resolution, which is promising to unfold minor differences and dynamic changes.

AbstractZinc (Zn)–dysprosium (Dy) binary alloys are promising biodegradable bone fracture fixation implants owing to their attractive biodegradability and mechanical properties. However, their clinical application is a challenge for bone fracture healing, due to the lack of Zn–Dy alloys with tailored proper bio‐mechanical and osteointegration properties for bone regeneration. A Zn‐5Dy alloy with high strength and ductility and a degradation rate aligned with the bone remodeling cycle is developed. Here, mechanical stability is further confirmed, proving that Zn‐5Dy alloy can resist aging in the degradation process, thus meeting the mechanical requirements of fracture fixation. In vitro cellular experiments reveal that the Zn‐5Dy alloy enhances osteogenesis and angiogenesis by elevating SIRT4‐mediated mitochondrial function. In vivo Micro‐CT, SEM‐EDS, and immunohistochemistry analyses further indicate good biosafety, suitable biodegradation rate, and great osteointegration of Zn‐5Dy alloy during bone healing, which also depends on the upregulation of SIRT4‐mediated mitochondrial events. Overall, the study is the first to report a Zn‐5Dy alloy that exerts remarkable osteointegration properties and has a strong potential to promote bone healing. Furthermore, the results highlight the importance of mitochondrial modulation and shall guide the future development of mitochondria‐targeting materials in enhancing bone fracture healing.

Published: January 2024

AbstractBone morphogenetic protein (BMP) signaling plays a vital role in differentiation, organogenesis, and various cell processes. As a member of TGF‐β superfamily, the BMP initiation usually accompanies crosstalk with other signaling pathways and simultaneously activates some of them. It is quite challenging to solely initiate an individual pathway. In this study, an opsin‐free optical method to specifically activate BMP receptors (BMPR) and subsequent pSmad1/5/8 cascades by a single‐time scan of a tightly‐focused femtosecond laser in the near infrared range is reported. Via transient two‐photon excitation to intrinsic local flavins near the cell membrane, the photoactivation drives conformational changes of preformed BMPR complexes to enable their bonding and phosphorylation of the GS domain in BMPR‐I by BMPR‐II. The pSmad1/5/8 signaling is initiated by this method, while p38 and pSmad2 are rarely perturbed. Based on a microscopic system, primary adipose‐derived stem cells in an area of 420  × 420 µm2 are photoactivated by a single‐time laser scanning for 1.5 s and exhibit pSmad1/5/8 upregulation and osteoblastic differentiation after 21 days. Hence, an opsin‐free, specific, and noninvasive optical method to initiate BMP signaling, easily accomplished by a two‐photon microscope system is reported.
