Published: April 2023

AbstractDespite extensive commercial and regulatory interventions, food spoilage and contamination continue to impose massive ramifications on human health and the global economy. Recognizing that such issues will be significantly eliminated by the accurate and timely monitoring of food quality markers, smart food sensors have garnered significant interest as platforms for both real‐time, in‐package food monitoring and on‐site commercial testing. In both cases, the sensitivity, stability, and efficiency of the developed sensors are largely informed by underlying material design, driving focus toward the creation of advanced materials optimized for such applications. Herein, a comprehensive review of emerging intelligent materials and sensors developed in this space is provided, through the lens of three key food quality markers – biogenic amines, pH, and pathogenic microbes. Each sensing platform is presented with targeted consideration toward the contributions of the underlying metallic or polymeric substrate to the sensing mechanism and detection performance. Further, the real‐world applicability of presented works is considered with respect to their capabilities, regulatory adherence, and commercial potential. Finally, a situational assessment of the current state of intelligent food monitoring technologies is provided, discussing material‐centric strategies to address their existing limitations, regulatory concerns, and commercial considerations.

AbstractCharge‐transport layers are essential for achieving electrically pumped perovskite lasers. However, their role in perovskite lasing is not fully understood. Here, the role of charge‐transport layers on the lasing actions of perovskite films is explored by investigating the amplified spontaneous emission (ASE) thresholds. A largely reduced ASE threshold and enhanced ASE intensity is demonstrated by introducing an additional hole transport layer poly(triaryl amine) (PTAA). It is shown that the key role of the PTAA layer is to accelerate the hot‐carrier cooling process by extracting holes in perovskites. With reduced hot holes, the Auger recombination loss is largely suppressed, resulting in decreased ASE threshold. This argument is further supported by the fact that the ASE threshold can be further reduced from 25.7 to 7.2 µJ cm−2 upon switching the pumping wavelength from 400 to 500 nm to directly avoid excess hot‐hole generation. This work exemplifies how to further reduce the ASE threshold with transport layer engineering through hot‐hole manipulation. This is critical to maintaining the excellent gain properties of perovskites when integrating them into electrical devices, paving the way for electrically pumped perovskite lasers.

AbstractLaser‐driven phosphor‐converted white light sources are highly desirable for their unprecedented energy efficiency and lighting quality. However, important challenges remain due to a lack of efficient and stable red‐emitting materials. Here Eu2+‐activated oxide‐based double perovskites are explored as red emitters with thermally stable photoluminescence. Sr3TaO5.5:Eu2+ ceramics exhibit a red emission band peaking at 620 nm upon blue laser pumping owing to the Eu2+ occupation at highly ordered substitutional lattice sites. A constructed laser‐driven white light wheel under an incident power density of 19.2 W mm−2 presents a record luminous flux of 1115 lm with an excellent color rendering index of 90. This study invigorates the development of Eu2+‐activated oxide‐based ceramics with thermally stable luminescence for laser‐pumped lighting and display applications.

Published: April 2023

AbstractDual‐ion batteries (DIBs) have been attracting great attention for the storage of stationary energy due to their low cost, environmental friendliness, and high working voltage. However, most reports on DIBs involve low‐mass‐loading electrodes (<2.5 mg), while the use of high mass‐loading electrodes (>10 mg cm−2), which are critical for practical application, is overlooked. Herein, an integrated free‐standing functional carbon positive electrode (named MSCG) with a “point‐line‐plane” hierarchical architecture at the practical level of ultrahigh mass‐loading (>50 mg cm−2) is developed for high‐energy‐density DIBs. The rationally designed microstructure and the advanced assembly method that is adopted produce a well‐interconnected ion/electron transport channel in the MSCG electrode, which confers rapid ion/electron kinetic properties while maintaining good mechanical properties. Consequently, the DIBs with ultrahigh‐mass‐loading MSCG electrodes exhibits a high discharge capacity of 100.5 mAh g−1 at 0.5 C (loading mass of 50 mg cm−2) and a long‐term cycling performance with a capacity retention of 87.7% at 1 C after 500 cycles (loading mass of 23 mg cm−2). Moreover, the DIB with the ultrahigh‐mass‐loading positive electrode achieves a high energy density of 379 Wh kg−1 based on the mass of electrode materials, the highest value recorded to date for any DIBs.

AbstractInfections are a significant risk to patients who receive medical implants, and can often lead to implant failure, tissue necrosis, and even amputation. So far, although various surface modification approaches are proposed for prevention and treatment of microbial biofilms on indwelling medical devices, most are too expensive/complicated to fabricate, unscalable, or limited in durability for clinical use. Here, this work presents a new bottom‐up design for fabricating scalable and durable nano‐patterned coatings with dynamic topography for long‐term antibacterial effects. This work shows that MXene layer‐by‐layer (LbL) self‐assembled coatings—with finely tunable crumpled structures with nanometer resolution and excellent mechanical durability—can be successfully fabricated on stretchable poly(dimethylsiloxane) (PDMS). The crumpled MXene coating with sharp‐edged peaks shows potent antibacterial effects against Staphylococcus aureus and Escherichia coli. In addition, this work finds that on‐demand dynamic deformation of the crumpled coating can remove ≥99% of adhered bacterial cells for both species, resulting in a clean surface with restored functionality. This approach offers improved practicality, scalability, and antibacterial durability over previous methods, and its flexibility may lend itself to many types of biomaterials and implantable devices.

AbstractThe skin serves as a crucial barrier against environmental insults and invading pathogens. However, traumatic injury or skin disorder can compromise this barrier function, leasing to bacterial colonization and infection of the wound with microorganisms such as Staphylococcus aureus, which are normally present on healthy skin. The secretion of bacterial proteases such as V8 protease from S. aureus can disturb the equilibrium between extracellular matrix degradation and deposition during wound healing resulting in loss of barrier integrity. We report the feasibility of a nitric oxide (NO) releasing poly‐ε‐lysine (pεK) hydrogel to prevent loss of barrier function caused by V8 proteases. The fabrication and characterization of the pεK hydrogel and NO releasing properties in biologically relevant media are reported. The NO‐releasing pεK hydrogel have demonstrated bactericidal activity against a clinical isolate of S. aureus in complex physiological media and concurrently reduce the catalytic activity of secreted V8 protease. Moreover, pεK hydrogels are cytocompatible with keratinocytes and dermal fibroblasts. In contrast, Penicillin G loaded pεK hydrogels showed excellent antimicrobial efficacy but did not affect V8 catalytic activity. This demonstrates that NO‐releasing pεK hydrogels hold potential as an effective treatment for infected wounds reducing the microbial burden and inactivating bacterial secreted proteases.

AbstractArrays of stretchable and transparent electronic sensors realize next‐generation skin‐conformable wearables and soft robotic skins, which require a high‐resolution patternable stretchable conductor. However, the difficulty of simultaneously engineering desirable material properties (i.e., conductivity, stretchability, and patternability) has limited the development of such stretchable electronic materials. Herein, a high‐resolution patternable, stretchable, and transparent conducting polymer by decoupled engineering of the material properties is shown. The high conductivity of the conducting polymer is achieved by rationally designing an ionic additive. The high stretchability is realized by matching the mechanical properties of the conducting polymer to the substrate. The developed conducting polymer is then patterned in a resolution less than 10 µm by nanosecond UV laser ablation, which enables the feasible demonstration of stretchable and transparent sensor arrays for touch and strain. The findings in this work will accelerate the development of high‐density stretchable sensor arrays and stretchable semiconductor devices.

AbstractProgrammed 4D printing shape‐memory polymers (SMPs) have been endorsed as an emerging paradigm for developing adaptive dynamic components with sophisticated architectures and biomimetic adaptation capacities. However, the species of SMPs systems are still rare while most of them are produced from expensive monomers which have restricted their mass production. Moreover, most SMPs show poor elongation at break and strain which cannot support a higher degree of bending during shape memory deformation. Herein, a kind of new epoxy vinyl ester resin ink is developed and improves the 4D printing process of shape memory epoxy‐based polymer. By adjusting the printing conditions to match the ink property, a series of precisely designed printing structures are successfully produced. The printed SMP system shows a favorable strain rate under heat‐treated conditions above its glass transition temperature (Tg) which leads to fine shape memory performance. Furthermore, the printed components obtained through micro to macro multi‐scale 4D printing structure design confirm its application potential as dynamic adaptive devices in aerospace and safety engineering.

AbstractLithium is a drug widely employed for the treatment of bipolar disorder owing to its high efficacy in mood management and suicide prevention. However, this efficacy is often undermined by misdosing and nonadherence, and diligent drug monitoring is required during treatment. Standard lithium monitoring involves invasive blood collections and laboratory analysis with low time granularity. Recent advances in sensor technology have enabled the development of personalized drug‐monitoring devices that analyze biomarker information noninvasively. Herein, based on the fact that the analyte partition onto the fingertip with a high flux, a touch‐based noninvasive monitoring modality for managing lithium pharmacotherapy is devised. The system is built based on a thin organohydrogel‐mounted lithium ion‐selective electrode (TOH‐ISE). The TOH coating provides a stable environment for sensing. Through the utilization of a water/glycerol bi‐solvent matrix, the gel exhibits dehydration‐resist properties, rendering a controlled micro‐environment for ISE conditioning, and subsequently minimizing signal drift. To illustrate the clinical application of the solution, the system is tested on a subject prescribed lithium. The system successfully detected the increase in circulating drug levels following medication intake. Collectively, the results indicate the devised solution is capable to facilitate lithium adherence monitoring and has broader potential for optimizing lithium pharmacotherapy.

AbstractAs a result of the widespread use of small‐scale and low‐power electronic devices, the demand for micro‐energy sources has increased, in particular the potential to harvest the wide variety of energy sources present in their surrounding environment. In this paper, a novel coupled nanogenerator that can realize energy harvesting for multiple energy sources is reported. Based on the unique electrical properties of ferroelectric Bi0.5Na0.5TiO3 (BNT) materials, it is possible to combine a photovoltaic cell, pyroelectric nanogenerator, and triboelectric‐piezoelectric nanogenerator in a single element to harvest light, heat, and mechanical energy simultaneously. To evaluate the effectiveness of coupling for different materials, a Yang coupling factor (kC,Q) is defined in terms of transferred charge, where BNT has the largest kC,Q of 1.29 during heating, indicating that BNT has the best coupling enhancement compared to common ferroelectric materials. This new criterion and novel device structure therefore provide a new basis for the future development of coupled nanogenerators which are capable of harvesting multiple sources of energy.

AbstractPlastic pollution has caused numerous environmental issues in recent decades. As one of the most commonly used packaging materials, aluminum‐plastic laminates (APL) are particularly challenging for recycling purposes due to their sophisticated materials components. This work reveals a new strategy to upcycle such post‐consumer APL packaging waste, e.g., chips‐bags, for passive daytime cooling applications. This opens an attractive route to reuse APLs while at the same time reducing global energy consumption and carbon emissions. The mirror‐like appearance of the APLs possesses a strong solar reflection, up to 86%. By coating, this reflective layer of the APL waste with a high emissive polydimethylsiloxane layer, a simple but effective passive daytime cooling foil is constructed, which shows promising passive cooling performance theoretically and practically. More importantly, the passive cooling foil based on APL waste is flexible and can be applied to any target object, protecting it from harsh sunlight. The low‐cost APL waste‐based passive cooling foil proposed in this work will significantly contribute to both energy and environmental issues that humans face today.

Published: April 2023

AbstractGold nanorods and cyanine dyes are promising to be widely used in photothermal therapy due to their adjustable absorption wavelength and excellent photothermal conversion efficiency. However, it is unclear how gold nanorods differ from cyanine dyes in therapeutic effects. Nanocapsules are synthesized from hybrid silica encapsulated gold nanorods (AuNRs@YSiO2, hereafter GNR@YS). Composite nanocapsules (hereafter GNR@YS‐CyN) are prepared from GNR@YS loaded with CyN to treat subcutaneous tumor. Cyanine dye (CyCl) with similar absorption to gold nanorods is also synthesized to match the existing commercial 808 nm laser. The results show that both materials have good therapeutic effect, but differ in healing scabs on skin tissue surface after tumor ablation. GNR@YS‐CyN are superior to CyCl in the treatment of subcutaneous tumor. This may be the size effect of GNR@YS‐CyN has permeability and retention enhancement effect at the tumor site. GNR@YS‐CyN have no obvious dye diffusion phenomenon, which reduces the damage to normal tissue.

AbstractThe malignant transformation of hepatic progenitor cells (HPCs) in the inflammatory microenvironment is the root cause of hepatocarcinogenesis. However, the potential molecular mechanisms are still elusive. The HPCs subgroup is identified by single‐cell RNA (scRNA) sequencing and the phenotype of HPCs is investigated in the primary HCC model. Bulk RNA sequencing (RNA‐seq) and proteomic analyses are also performed on HPC‐derived organoids. It is found that tumors are formed from HPCs in peritumor tissue at the 16th week in a HCC model. Furthermore, it is confirmed that the macrophage‐derived TWEAK/Fn14 promoted the expression of inhibitor of differentiation‐1 (ID1) in HPCs via NF‐κB signaling and a high level of ID1 induced aberrant differentiation of HPCs. Mechanistically, ID1 suppressed differentiation and promoted proliferation in HPCs through the inhibition of HNF4α and Rap1GAP transcriptions. Finally, scRNA sequencing of HCC patients and investigation of clinical specimens also verified that the expression of ID1 is correlated with aberrant differentiation of HPCs into cancer stem cells, patients with high levels of ID1 in HPCs showed a poorer prognosis. This study provides important intervention targets and a theoretical basis for the clinical diagnosis and treatment of HCC.

AbstractTraditional lithium‐ion batteries cannot meet the ever‐increasing energy demands due to the unsatisfied graphite anode with sluggish electrochemical kinetics. Recently, the perovskite material family as anode attracts growing attention due to their advantages on specific capacity, rate capability, lifetime, and safety. Herein, a double perovskite La2MnNiO6 synthesized by solid‐state reaction method as a high‐performance anode material for LIBs is reported. La2MnNiO6 with an average operating potential of <0.8 V versus Li+/Li exhibits a good rate capability. Besides, the Li|La2MnNiO6 cells perform long cycle life without decay after 1000 cycles at 1C and a high cycling retention of 93% is observed after 3000 cycles at 6C. It reveals that this material maintains stable perovskite structure with cycling. Theoretical calculations further demonstrate the high electronic conductivity, low diffusion energy barrier, and structural stability of the lithiated La2MnNiO6. This study highlights the double perovskite type material as a promising anode for next‐generation batteries.
