Published: May 2023

AbstractContinuous monitoring of human sweat, which enables highly sensitive multiple biomarkers analysis with a portable power supply, is increasingly desired for the remote healthcare industry. Smart fibers with on‐demand functionality are ideal candidates for fabricating noninvasive and conformal bioelectronic devices owing to their considerable flexibility. Herein, a multifunctional textile patch based on a reduced graphene oxide (rGO)/tetra‐aniline (TANi) fiber for simultaneous biomarker monitoring and energy supply is reported. Benefiting from the multi‐electrochemical redox states and proton doping/dedoping characteristics of TANi, rGO/TANi hybrid fibers are combined into an energy storage device and biosensor in a physiological environment. GO flakes increase the viscoelasticity of the wet‐spinning dope by regulating the noncovalent interactions between TANi aggregates, thereby enhancing the mechanical strength and conductivity of the resulting rGO/TANi hybrid fiber. Consequently, the hybrid fiber exhibits high volumetric capacitance and versatile sensing capability for various physiological analytes, e.g., pH, K+, and glucose in sweat electrolyte. Furthermore, a wireless continuous sweat monitoring system is constructed by integrating the multifunctional fiber sensor into a printed electric circuit board with programmed functionality. Such a delicate integrated design that harnesses the signal collection and communication units is anticipated to facilitate practical applications in personalized diagnostic and physiological health.

Published: May 2023

AbstractCovalent triazine frameworks (CTF) offer a tunable platform for photocatalytic H2 generation due to their diverse structures, low costs, and precisely tunable electronic structures. However, high exciton binding energy and short lifetimes of photogenerated carriers restrict their application in photocatalytic hydrogen evolution. Herein, a novel phosphorus‐incorporated CTF is introduced to construct a chemically bonded PCTF/WO3 (PCTFW) heterostructure with a precise interface electron transfer channel. The phosphorus incorporation is found to dominantly reduce the exciton binding energy and promote the dissociation of singlet and triplet excitons into free charge carriers due to the regulation of electronic structures. High‐quality interfacial WN bonds improve the interfacial transfer of photogenerated electrons, thus prolonging the lifetime of photogenerated electrons. Femtosecond transient absorption spectroscopy characterizations and DFT calculations further confirm both phosphorus incorporation and Z‐scheme heterojunctions can synergistically boost the in‐built electric field and accelerate the migration and separation of photogenerated electrons. The optimized photocatalytic H2‐evolution rate of resultant PCTFW is 134.84 µmol h−1 (67.42 mmol h−1g−1), with an apparent quantum efficiency of 37.63% at 420 nm, surpassing many reported CTF‐based photocatalysts so far. This work highlights the significance of atom‐level interfacial exciton dissociation, and charge transfer and separation in improving photocatalysis.

Published: May 2023

AbstractMagnetic skyrmions are topologically protected chiral spin textures that hold great promise for information storage and processing. The current research efforts on magnetic skyrmions are exclusively based on d‐orbital magnetism, which restricts their existence in a narrow window of temperature‐external magnetic field (T‐B) phase diagram. Herein, employing first‐principles and Monte‐Carlo simulations, the work reports the identification of d0 magnetic skyrmions in 2D lattice of Tl2NO2. Arising from inversion asymmetry and strong spin‐orbit coupling compensated by ligand of heavy element, large Dzyaloshinskii–Moriya interaction is obtained in monolayer Tl2NO2. This, competed with p‐orbital exchange interaction, leads to the d0 skyrmion physics under external magnetic field. Importantly, different from d‐orbital topological magnetism, the d0 magnetic skyrmions can be stabilized in a wide window of T‐B phase diagram. The underlying physics is related to the small magnetic moment and delocalization character of d0 magnetism. Furthermore, the work also demonstrates that the d0 magnetic skyrmions are strongly coupled with ferroelectricity. These findings open a new direction for magnetic skyrmion research.

AbstractThe polarity of lipid droplets (LDs) plays an important role in pathological processes associated with abnormal lipid metabolism. Monitoring the variation of LDs polarity in cells and tissues is of great importance in biomedical research and clinical diagnosis. However, developing fluorescent LDs‐specific probes with high polarity sensitivity, brightness, and permeability for deep tissue imaging is still challenging. Herein, a push–pull fluorescent luminogen (DPBT) with aggregation‐induced emission, strong solvatochromism, large Stokes shift, high solid‐state fluorescence efficiency and superior two‐photon absorption is facilely developed. The lipophilic DPBT can specifically stain LDs with high biocompatibility and good photostability. The viscosity‐enhanced solvatochromic emission property enables DPBT to visualize LDs polarity with high brightness and imaging contrast, and deep penetration depth under two‐photon microscopy. DPBT can specifically stain lipids in various mouse tissues (atherosclerotic plaque, liver, and mesenteric adipose tissues) and map their polarity distribution to reflect lipid metabolic states within those tissues. It is found that the lipids deposition as well as their polarity distribution in tissues of hyperlipoidemia mouse are clearly different from the tissues of the normal mouse. Its excellent properties make DPBT a promising candidate for investigating LDs‐associated physiological and pathological processes in live biological samples.

AbstractThe hierarchical network of blood vessels comprises the larger vessels (veins and arteries), the smaller ones (venules and arterioles), and the thinnest capillaries. The proper functioning of most tissues in the body relies on vascularization, which is meant for the diffusion of gases, nutrients, and harmful waste. However, it is known that cell survival is compromised as the diffusion of oxygen is limited beyond 100–200 µm and damage can occur at any level of the complex system of the vascular network, as is the case in cardiovascular, musculoskeletal, and neurovascular diseases that recur and progress with age. These may prove fatal, hence the need for vascular tissue engineering (VTE) arises. VTE mainly focuses on the fabrication of vascular constructs using natural, synthetic material, or a combination of both using various techniques. The construct is expected to integrate and anastomose with the host vasculature. 4D bioprinting is an emerging field that allows the fabrication of hollow tubes employing different materials that respond to different stimuli. This review is a comprehensive summary of the major techniques employed in VTE and the recent technique of 4D bioprinting foreseen to revolutionize the field.

Published: May 2023

AbstractPlasmonic nanoparticles with strong chiral optical activity are promising systems for a wide range of applications. Self‐assembly of achiral metallic nanoparticles thanks to chiral molecules or templates is a well‐known strategy to prepare chiral plasmonic nanomaterials. In this work, the assembly of chiral plasmonic particles without using a chiral templating agent is investigated. For that purpose, previously developed chiral core‐shell Au@Ag and Au@Au particles are assembled in a controlled way by lowering the surfactant concentration in solution. The assembly leads to pseudo‐linear structures that are revealed by electron microscopy, and the plasmonic responses are characterized by circular dichroism (CD) and UV‐Vis‐NIR spectroscopies. The chiral optical response strongly depends on the system and assembly conditions. For Au@Ag, the CD signal is tuned with contributions appearing in the red region of the spectrum, while for Au@Au, the CD response is unexpectedly lost. The origin of this difference remains undetermined, it is hypothesized that the coupling of circular dichroism modes or the generation of chiral superstructures may influence the chiroptical properties. These experimental results highlight the non‐obvious and complex nature of the chirality generation mechanisms in such plasmonic systems.

AbstractCamouflage skills are important for understanding the relationship between predators and prey in ecological systems. Mimicry is a common strategy used by creatures to alter their appearance in order to blend in with their surroundings and avoid detection. This paper unveils a previously unknown camouflage strategy that creates false object information and positions of an object in the visual range of radar sensor vision. A dispersion‐modulated illusionary metasurface to realize focal spot coding in a 3‐dimensional space to fit the radar imaging process is proposed. As the radar image indicates, an aircraft image is created by a flat metasurface plane with good polarization adaptation ability. Design, simulation, and experimental results validate the study. This camouflage strategy indicates the complexity of the food chain and can be used by both predators and prey, providing accessible insights for maintaining biological diversity. The metasurface‐based system can be potentially utilized in future radar markers for marine traffic control systems.

AbstractThe concept of geometric phase has attracted enormous interest in the metasurface community for achieving phase variation with simple geometrical rotation. Here, this work demonstrates for the first time a highly efficient dual‐band metasurface with independent phase responses for structures with different‐fold rotational symmetries. For proof of concept, a hybrid unit cell structure with nested resonators of different‐fold (single‐fold and threefold) is proposed, where geometric rotation independent phase shifts of two times and six times the rotation angle are achieved in lower and higher bands, respectively. By rotating the resonators within the unit cell, highly efficient independent full phase controls can be achieved with circularly polarized incident waves. The co‐polarized reflection efficiency exceeds 90% at the frequency domain from 10.95 to 11.75 GHz (corresponding to the inner resonator) and exceeds 80% between 14.10 and 14.43 GHz (corresponding to the outer resonator), with peak values of 94.7% at 11.55 GHz and 85.5% at 14.23 GHz, respectively. To validate the versatility of the design paradigm, a metasurface porotype is fabricated and experimentally tested by generating independent holographic images.

Published: May 2023

AbstractDemand for lightweight and efficient electromagnetic wave (EW) absorbers continues to increase with technological advances in highly integrated electronics and military applications. Although MXene‐based EW absorbers have been extensively developed, more efficient electromagnetic coupling and thinner thickness are still essential. Recently, ordered heterogeneous materials have emerged as a novel design concept to address the bottleneck faced by current material development. Herein, an ordered heterostructured engineering to assemble Ti3CNTx MXenes/Aramid nanofibers/FeCo@SiO2 nanobundles (FS) aerogel (AMFS‐O) is proposed, where the commonly disordered magnetic composition is transformed to ordered FS arrays that provide more powerful magnetic loss capacity. Experiments and simulations reveal that the anisotropy magnetic networks enhance the response to the magnetic field vector of EW, which effectively improves the impedance matching and makes the reflection loss (RL) peaks shift to lower frequencies, leading to the thinner matching thickness. Furthermore, the temperature stability and excellent compressibility of AMFS‐O expand functionalized applications. The synthesized AMFS‐O achieves full‐wave absorption in X and Ku‐band (8.2–18.0 GHz) at 3.0 mm with a RLmin of −41 dB and a low density of 0.008 g cm−3. These results suggest that ordered heterostructured engineering is an effective strategy for designing high‐performance multifunctional EW absorbers.

Published: May 2023

AbstractCompliant thermoelectric generators (TEGs) can fully exploit their energy conversion efficiency by establishing conformal interfaces on arbitrarily shaped 3D heat sources. Although additive manufacturing processes allow scalable fabrication with flexibility and customizability, most printable TEGs are fabricated as planar‐type devices that harvest heat only in the in‐plane direction. Herein, 3D‐compliant TEGs fabricated solely using direct ink writing, which enables thermal‐transfer optimization for efficient through‐plane heat‐to‐electricity conversion owing to the out‐of‐plane printing of viscoelastic thermoelectric (TE) inks and unique device design is proposed. The rheological properties of carbon nanotube (CNT) TE inks are engineered to ensure conformal printing along directly written vertical thermal insulators. The ink TE properties are enhanced by the fine‐tuned incorporation of p‐ and n‐type dopants, where the electrical conductivity is further facilitated by nozzle‐induced CNT packing to achieve high‐power factors. To minimize the parasitic thermal loss from heat sources, an ultra‐thin bottom substrate is directly printed with polydimethylsiloxane, thereby realizing compliant 3D TEGs for heat harvesting in the out‐of‐plane direction. The TEG exhibits the highest normalized open‐circuit voltage (0.28 mV K−1 cm−2) among the additively manufactured TEGs and retains remarkable mechanical reliability against repetitive deformation, promising its potential as body heat harvesters or temperature sensors.

AbstractHigh tunability of both ionic liquids (ILs) and metal organic frameworks (MOFs) enables great opportunity in the rational designation of IL/MOF composites for physical adsorption and separation. Traditionally, cations and anions of ILs as an entirety are combined with MOFs either inside or outside the microchannels. Herein, organic cations of ILs were confined into Cu‐BTC and the champion adsorbent is obtained by using 1‐propionic acid‐3‐vinylimidazole bromide as the precursor with a moderate loading amount, exhibiting higher CO2 uptakes of 8/5 mmol g−1 than Cu‐BTC (6.0/3.5 mmol g−1) at 273/298 K and 100 kPa, associating with significantly improved CO2/N2(CH4) selectivities. The organic cations are interacted with two adjacent CuII2(CRO2)2 paddle wheel units of Cu‐BTC, expanding the CuO bond to strengthen the CO2 affinity of open Cu sites and also serving as an additive CO2 adsorptive site. The promotion of CO2 capture ability is further reflected in the dynamic column breakthrough experiment.

Published: May 2023

AbstractINTRODUCTIONAlzheimer's disease (AD) is a neurodegenerative disease with increasing relevance as dementia cases rise. The etiology of AD is widely debated. The Calcium Hypothesis of Alzheimer's disease and brain aging states that the dysfunction of calcium signaling is the final common pathway leading to neurodegeneration. When the Calcium Hypothesis was originally coined, the technology did not exist to test it, but with the advent of Yellow Cameleon 3.6 (YC3.6) we are able to test its validity.METHODSHere we review use of YC3.6 in studying Alzheimer's disease using mouse models and discuss whether these studies support or refute the Calcium Hypothesis.RESULTSYC3.6 studies showed that amyloidosis preceded dysfunction in neuronal calcium signaling and changes in synapse structure. This evidence supports the Calcium Hypothesis.DISCUSSIONIn vivo YC3.6 studies point to calcium signaling as a promising therapeutic target; however, additional work is necessary to translate these findings to humans.

Published: May 2023

AbstractFerroelectric thin films have recently received unprecedented attention due to the need to miniaturize electronic circuit devices. Synthesis and deposition processes along with theoretical calculations are improved remarkably to realize stable ferroelectric thin films up to nanometer thickness. However, even with technological advances, it is still difficult to overcome the size effect of ferroelectrics, so research is being conducted to achieve stable ferroelectricity in unit‐cell thicknesses thinner than the typical critical thicknesses. In this review, the size effects in ferroelectric thin films are described, and their importance and fundamental limitations are discussed. First, intrinsic and extrinsic factors affecting ferroelectricity are introduced based on the theoretical background of the size effects in ferroelectricity. Then, on understanding the size effects by considering complex interacting factors, the recent works showing ferroelectricity below the commonly known critical thicknesses in perovskite, fluorite oxides, and two‐dimensional (2D) ferroelectrics are introduced. Finally, the results of research efforts in scaling ferroelectric thin films with a future perspective are summarized.

AbstractThe turnip aphid,Lipaphis erysimiKaltenbach, inflicts heavy damage on cruciferous crops worldwide. In these insects, olfactory perception is crucial for mating, host location, and oviposition. Both odorant‐binding proteins (OBPs) and chemosensory proteins (CSPs) are responsible for the delivery of host odorants and pheromones during initial molecular interactions. In this study, antennal and body transcriptomes ofL. erysimiwere generated through the deep sequencing of RNA libraries. A dataset of 11LeryOBPand fourLeryCSPtranscripts was identified among assembled unigenes and subjected to sequence analysis. Phylogenetic analysis found a one‐to‐one orthologous relationship between LeryOBP/LeryCSP and its corresponding homologs from other aphid species. Further quantitative real‐time PCR analyses across developmental stages and tissues showed that fiveLeryOBPgenes (i.e.,LeryGOBP,LeryOBP6,LeryOBP7,LeryOBP9, andLeryOBP13) andLeryCSP10were specifically or significantly elevated in the antennae compared with other tissues. Moreover, two transcripts (i.e.,LeryGOBPandLeryOBP6) exhibited remarkably higher expression levels in alate aphids, implying their potentially functional role in the perception of new host plant locations. These results present the identification and expression of OBP/CSP genes inL. erysimi, providing valuable insights into their putative role in olfactory signal transduction.

Published: May 2023

AbstractAll‐oxide solid‐state sodium batteries (AOSSSBs), which are composed of oxide electrolytes and oxide active materials with sodium‐ion carriers, have attracted attention because of their high safety and material abundance. However, the operating voltage of AOSSSBs is inevitably low because the number of active materials available for use in AOSSSBs is restricted by undesirable reactions at electrolyte/electrode interfaces during high‐temperature fabrication. Herein, we fabricate AOSSSBs using a Na superionic conductor‐type solid electrolyte Na3Zr2(SiO4)2(PO4) (NZSP), a Na superionic conductor‐type negative active material NaTi2(PO4)3, and a mixed‐phosphate cathode active material Na4Ni3(PO4)2(P2O7) by a Na2B4O7 ⋅ 10H2O‐assisted low‐temperature fabrication technique. The obtained NaTi2(PO4)3/NZSP/Na4Ni3(PO4)2(P2O7) batteries exhibit an average discharge voltage of 3.1 V, which is the highest voltage ever reported in AOSSSBs. In addition, Na2B4O7 ⋅ 10H2O‐containing NZSP electrolytes show a wider electrochemical window in comparison with the pristine NZSP, enabling the batteries to endure a wide voltage operation (a capacity retention of 71 % after 10 cycles of charge/discharge in 0–5.1 V).
