AbstractBroadband emissive perovskites are next‐generation materials for solid‐state lighting and radiative detection. However, white‐emitting perovskites are generally synthesized by regulating B/X sites, while not enough attention is paid to the A‐site, which is thought to hardly affect the band‐edge structures and optoelectronic properties. Here, a series of Sb3+‐doped In‐based 0D halide perovskite derivatives are described with various organoammonium cations in A‐sites. Warm‐white light emitting across the visible spectrum (450–850 nm), large Stokes shifts, and high photoluminescence quantum yields are easily tunable by molecularly tailoring A‐site cations. These features enable a light yield up to 60976 Photons/MeV as X‐ray scintillator, and a detection limit of 90 nGyair/s that is ≈60 times lower than the medical requirement. It is proved that A‐site plays a critical role in determining the degree of distortion of polyhedra, which influences the broadband photoluminescence and self‐trapped exciton (STE) dominates the emission process. Moreover, for the first time, via the incorporation of 2,6‐dimethylpiperazine, a mixed A‐site regulating strategy produces a standard white‐light emission, which originates from the blue‐light and yellow‐light related to various STE emission centers. It is foreseen that this strategy highlights the expanded role of A‐site and the importance of rethinking A‐sites in perovskites.

AbstractHeart failure with preserved ejection fraction (HFpEF) is a major challenge in cardiovascular medicine, accounting for ≈50% of all cases of heart failure. Despite the ongoing efforts, no medical device has yet received FDA approval. This is largely due to the lack of an in vivo model of the HFpEF hemodynamics, resulting in the inability to evaluate device effectiveness in vivo prior to clinical trials. Here, the development of a highly tunable porcine model of HFpEF hemodynamics is described using implantable soft robotic sleeves, where controlled actuation of a left ventricular and an aortic sleeve can recapitulate changes in ventricular compliance and afterload associated with a broad spectrum of HFpEF hemodynamic phenotypes. The feasibility of the proposed model in preclinical testing is demonstrated by evaluating the hemodynamic response of the model post‐implantation of an interatrial shunt device, which is found to be consistent with findings from in silico studies and clinical trials. This work overcomes limitations of prior HFpEF models, such as low hemodynamic accuracy, high costs, and long development phases. The versatile and adjustable platform introduced can transform HFpEF device development, aiming to enhance the lives of the 32 million people affected globally.

Published: November 2023

AbstractBisphenol A (BPA) is a prevalent endocrine disruptor found in natural environments. Exposure to BPA has been associated with male infertility. The natural phytochemical icariin (ICA) has demonstrated significant promise for the treatment of male infertility. However, its effectiveness is limited due to its low bioavailability, poor water solubility, and insufficient targeting abilities. Herein, novel nanoparticles are generated from the natural silk fibroin, which are used to load ICA. The efficient drug delivery system (ICA‐SNPs) result in significantly focused drug distribution to spermatogonium, enhancing the anti‐infertility properties of ICA, and can effectively mitigate spermatogenesis dysfunction induced by BPA, control serum sex hormone levels, and enhance testicular ultrastructure. Additionally, the ICA‐SNPs restore spermatogenesis dysfunction primarily via the hormone biosynthesis, spermatogonium meiosis process, and glycerophospholipid metabolism.

AbstractBioprinting applications in the clinical field generate great interest, but developing suitable biomaterial inks for medical settings is a challenge. Placental tissues offer a promising solution due to their abundance, stability, and status as medical waste. They contain basement membrane components, have a clinical history, and support angiogenesis. This study formulates bioinks from two placental tissues, amnion (AM) and chorion (CHO), and compares their unique extracellular matrix (ECM) and growth factor compositions. Rheological properties of the bioinks are evaluated for bioprinting and maturation of human endothelial cells. Both AM and Cho‐derived bioinks sustained human endothelial cell viability, proliferation, and maturation, promoting optimal vasculogenesis. These bioinks derived from human sources have significant potential for tissue engineering applications, particularly in supporting vasculogenesis. This research contributes to the advancement of tissue engineering and regenerative medicine, bringing everyone closer to clinically viable bioprinting solutions using placental tissues as valuable biomaterials.

Published: November 2023

AbstractMicrochannels with integrated pillars have enhanced the production capabilities and performance of various applications due to their high surface‐to‐volume ratio. However, emerging gas bubbles can become trapped, potentially limiting the functionality or efficiency of the device when scaled down to the low‐micrometer scale. Understanding the conditions required to dislodge these bubbles is thus critical for optimizing microfluidic devices with complex physical behaviors. Here an analytical model is presented that outlines the dislodgment conditions and driving forces for such gas–liquid flows. These terms are derived from the gas–liquid interface properties, geometry, and processing parameters. As the density of the pillar arrangement is scaled down, the resistance to bubble dislodgment typically increases. Nevertheless, the bubble is compelled to dislodge at lower pressure loads when critical volumes are reached. This newly discovered effect is particularly noticeable in densely packed arrays and can be explained by the interplay of increased surface tension, geometrical restrictions, and volume‐preserving forces. The analytical terms and effects are validated through novel experimental and numerical methods tailored for microchannels in the low‐micrometer scale, showing strong agreement.

Published: November 2023

AbstractRecently, novel 2D materials with fascinating characteristics are extensively applied to design/fabricate high‐activity and cost‐effective photocatalysts for solar‐driven fuels/chemicals generation. Among these 2D materials, HfS2 nanosheets (NSs) exhibit excellent features of large surface area, short bulk‐to‐surface distance, alterable band structures, and vast catalytic sites. Despite these features, no realistic experimental works on HfS2‐based materials are reported in photocatalysis field. Moreover, it is interesting but challenging to realize atomic‐scale engineering of compositions/structures for novel 2D materials and to relate these atomic‐scale characteristics with the element/space/time‐resolved charge kinetics of 2D materials‐based photocatalysts. Herein, for the first time, atomic‐scale defected HfS2 NSs are designed/synthesized. The as‐synthesized HfS2 NSs are combined with various photocatalysts to acquire novel HfS2‐TiO2, HfS2‐CdS, HfS2‐ZnIn2S4, and HfS2‐C3N4 composites, respectively. Among them, HfS2‐CdS exhibits the highest rate (5971 µmol g−1 h−1) on hydrogen (H2) evolution in triethanolamine aqueous solution, together with obviously‐enhanced rates on H2 (2419 µmol g−1 h−1) and benzaldehyde (5.11 mmol g−1 h−1) evolution in benzyl alcohol aqueous solution. Various state‐of‐art characterizations reveal the element/space/time‐resolved electron/hole kinetics in HfS2‐CdS composites, disclosing that these atomic‐scale S vacancies temporarily trapping electrons to facilitate spatiotemporal electron–hole separation/transfer. This work paves avenues to atomic‐scale design/synthesis of new 2D‐materials‐based photocatalysts for sunlight utilization.

Published: November 2023

AbstractHerein, oxygen‐incorporated 2D‐SnSe2 layered films are successfully fabricated by a plasma‐assisted selenization process. The oxygen concentrations inside the 2D‐SnSe2 layered film are controllable by controlling the proportion of hydrogen in the mixed gas of nitrogen and hydrogen during the plasma‐assisted selenization reaction. Oxygen atoms mainly exist in the form of the incorporated oxygen in the 2D‐SnSe2 layered film with an exceedingly small grain size of SnO2, which significantly increases the total interface area of the SnO2/SnSe2. Significant enhancement of the gas response to NO2 (709% under 100 ppb NO2) is reached when the proportion of hydrogen during the plasma‐assisted selenization process is 25%, thus showing excellent sensitivity and selectivity. Moreover, the sensor also demonstrated excellent stability under an increase in relative humidity. It is verified that the response will not significantly decrease when the relative humidity is below 90%. The obtained results demonstrate that oxygen‐incorporated 2D‐SnSe2 layered film with excellent commercial potential, is a highly suitable candidate for next‐generation gas sensors.

AbstractA concise method for the synthesis furan and benzene fused 2‐tetralones via photo‐induced rearrangement of 2′‐(furan‐2‐yl)‐[1,1′‐biphenyl]‐4‐ols was developed. Under argon atmosphere and room temperature, 6,7‐dihydrophenanthro[9,10‐b]furan‐5(4H)‐ones were obtained by irradiating 2′‐(furan‐2‐yl)‐[1,1′‐biphenyl]‐4‐ols with a 254 nm UV lamp (64 W) in dichloromethane (DCM) for 1 hour. The reaction mechanism includes 6π‐electrocyclization, thermal suprafacial [1,5]‐H shift, double thermal suprafacial [1,3]‐H shift and keto‐enol isomerization.
One‐Pot Access to 3‐Sulfonyl Flavones via K2CO3‐Mediated Annulation of α‐Sulfonyl o‐Hydroxyacetophenones with Substituted Nitriles

Published: November 2023

AbstractThe one‐pot construction of diversified sulfonyl flavones was developed by K2CO3‐mediated formal (5+1) stepwise annulation of α‐sulfonyl o‐hydroxyacetophenones with substituted nitriles under the open‐flask atmosphere conditions. A plausible mechanism is proposed and discussed. This method provides intermolecular and intramolecular ring‐closure via the formations of one carbon‐oxygen single (C−O) bond, one carbon‐carbon (C=C) double bond, and the cleavage of one carbon‐nitrile triple (C≡N) bond.

Published: November 2023

AbstractA divergent synthesis of ortho‐anisidines was achieved by controlling Cu‐catalyzed [1,3]‐methoxy rearrangement. The reactions of N‐alkoxyanilines having an electron‐donating group (EDG), such as an alkyl or anisyl group, at the ortho position and a pivaloyl group on the nitrogen atom in the presence of catalytic amounts of IPrMeCuCl and AgNTf2 afforded the corresponding 6‐substituted 2‐anisidines with good product selectivity through a [1,3]‐rearrangement of the methoxy group to the unsubstituted ortho position. In contrast, the reactions of N‐ methoxyanilines having a benzyloxycarbonyl group on the nitrogen atom using IPrCuBr and AgBF4 as catalysts afforded 3‐substituted 2‐anisidines via a domino process involving a [1,3]‐rearrangement of the methoxy group to the EDG‐substituted ortho position followed by a [1,2]‐rearrangement of the EDG of the resulting ortho‐quinol imine intermediate.

AbstractTopological transition metal dichalcogenides (TMDCs) have attracted much attention due to their potential applications in spintronics and quantum computations. In this work, the structural and electronic properties of topological TMDCs candidate ZrTe2 are systematically investigated under high pressure. A pressure‐induced Lifshitz transition is evidenced by the change of charge carrier type as well as the Fermi surface. Superconductivity is observed at around 8.3 GPa without structural phase transition. A typical dome‐shape phase diagram is obtained with the maximum Tc of 5.6 K for ZrTe2. Furthermore, the theoretical calculations suggest the presence of multiple pressure‐induced topological quantum phase transitions, which coexists with emergence of superconductivity. The results demonstrate that ZrTe2 with nontrivial topology of electronic states displays new ground states upon compression.

Published: November 2023

AbstractPhotonic crystals with mechanochromic properties are currently under intensive study to provide intuitive colorimetric detection of strains for various applications. However, the sensitivity of color change to strain is intrinsically limited, as the degree of deformation determines the wavelength shift. To overcome this limitation, auxetic photonic patterns that exhibit ultra‐sensitive mechanochromism are designed. These patterns have a regular arrangement of cuts that expand to accommodate the strain, while the skeletal framework undergoes torsional deformation. Elastic photonic crystals composed of a non‐close‐packed array of colloidal particles are embedded in the cut area of the auxetic patterns. As the cut area amplifies the strains, the elastic photonic crystals show significant color change even for small total strains. The degree of local‐strain amplification, or sensitivity of color change, is controllable by adjusting the width of cuts in the auxetic framework. In this work, a maximum sensitivity of up to 60 nm/% is achieved, which is 20 times higher than bulk films. It is believed that the auxetic photonic patterns with ultra‐sensitive mechanochromism will provide new opportunities for the pragmatic use of mechanochromic materials in various fields, including structural health monitoring.

AbstractSynthetic insecticides are widely used against plant pest insects to protect the crops. However, many insecticides have poor selectivity and are toxic also to beneficial insects, animals, and humans. In addition, insecticide residues can remain on fruits for many days, jeopardizing food safety. For these reasons, a reusable, low‐cost electronic trap that can attract, detect, and identify, but attack only the pest while leaving beneficial insects unharmed could provide a sustainable, nature‐friendly replacement. Here, for the first time, research results are presented suggesting the great potential and compatibility of organic electronic devices and technologies with pest management. Electrical characterizations confirm that an insect's body has relatively high dielectric permittivity. Adaptive memcapacitor circuits can track the impedance change for insect detection. Other experiments show that printed polymer piezoelectric transducers on a plastic substrate can collect information about the weight and activity of insects for identification. The breakdown voltage of most insects´ integument is measured to be <200 V. Long channel organic transistors easily work at such high voltages while being safe to touch for humans thanks to their inherent low current. This feasibility study paves the way for the future development of organic electronics for physical pest control and biodiversity protection.

AbstractLight‐driven actuators are widely used for smart devices such as soft robots. One of the main challenges for actuators is achieving rapid responsiveness, in addition to ensuring favorable mechanical properties. Herein, we focused on photoresponsive polyurethane (CD‐Azo‐PU) based on controlling the crystallization of the hard segments in polyurethane (PU) by complexation between azobenzene (Azo) and cyclodextrins (CDs). CD‐Azo‐PU incorporated polyurethane as the main chain and a 1:2 inclusion complex between Azo and γCD as a movable crosslink point. Upon ultraviolet light (UV, λ = 365 nm) irradiation, the photoresponsiveness of CD‐Azo‐PU bent toward the light source (defined as positive), while that of the linear Azo polyurethane (Azo‐LPU) without peracetylated γ‐cyclodextrin diol (TAcγCD‐diOH) as a movable crosslinker bent in the direction opposite the light source. The bending rates were determined to be 0.25°/s for CD‐Azo‐PU and 0.083°/s for Azo‐LPU, indicating that the bending rate for CD‐Azo‐PU was faster than that for Azo‐LPU. By incorporating movable crosslinks into CD‐Azo‐PU, we successfully achieved specific photoresponsive actuation with an enhanced rate.

Published: November 2023

AbstractHigh‐pressure chemistry has provided a huge boost to the development of scientific community. Pressure‐induced emission (PIE) in halide perovskites is gradually showing its unique charm in both pressure sensing and optoelectronic device applications. Moreover, the PIE retention of halide perovskites under ambient conditions is of great commercial value. Herein, we mainly focus on the potential applications of PIE and PIE retention in metal halide perovskites for scintillators and solid‐state lighting. Based on the performance requirements of scintillator and single‐component white light‐emitting diodes (WLEDs), the significance of PIE and PIE retention is critically clarified, aiming to design and synthesize materials used for high‐performance optoelectronic devices. This perspective not only demonstrates promising applications of PIE in the fields of scintillators and WLEDs, but also provides potential applications in display imaging and anti‐counterfeiting of PIE materials. Furthermore, solving the scientific disputes that exist under ambient conditions is also simply discussed as an outlook by introducing high‐pressure dimension to produce PIE.

AbstractHydrogel‐based microfluidics have emerged as a promising platform for constructing organs‐on‐chips, offering in vivo‐relevant micro‐environments. However, the fabrication of complex microchannels using hydrogels remains challenging and often fails to replicate the intricate organ structures. Here, we introduce a novel methodology called “layer‐by‐layer adhesion” for the construction of complex microfluidic chips. Leveraging a hydrosoluble and photo‐crosslinkable adhesive, chitosan methacryloyl (CS‐MA), we successfully stitched various hydrogels together in a layer‐by‐layer fashion to form perfusable microchannels. Our results demonstrate the versatility of CS‐MA in bonding different hydrogels, with adhesion energies ranging from 1.2 to 140 N m−1. By implementing the layer‐by‐layer adhesion approach, heterogeneous hydrogel‐based microchannels were fabricated with diverse morphologies. We applied this technique to establish liver‐on‐a‐chip by entrapping hepatic cells within a biocompatible gelatin methacryloyl layer and overlaying it with perfusable microchannels in a robust F127‐DA layer. The “layer‐by‐layer adhesion” technique offers a facile, efficient, and cytocompatible approach for engineering user‐defined hydrogel‐based chips.

Published: November 2023

AbstractTherapeutic peptides are a major class of pharmaceutical drugs owing to their target‐binding specificity as well as their versatility in inhibiting aberrant protein‐protein interactions associated with human pathologies. Within the realm of amyloid diseases, the use of peptides and peptidomimetics tailor‐designed to overcome amyloidogenesis has been an active research endeavor since the late 90s. In more recent years, incorporating nanoparticles for enhancing the biocirculation and delivery of peptide drugs has emerged as a frontier in nanomedicine, and nanoparticles have further demonstrated a potency against amyloid aggregation and cellular inflammation to rival strategies employing small molecules, peptides, and antibodies. Despite these efforts, however, a fundamental understanding of the chemistry, characteristics and function of peptido‐nanocomposites is lacking, and a systematic analysis of such strategy for combating a range of amyloid pathogeneses is missing. Here we review the history, principles and evolving chemistry of constructing peptido‐nanocomposites from bottom up and discuss their future application against amyloid diseases that debilitate a significant portion of the global population.
