Published: January 2024

AbstractAn integrated design, modeling, and multi‐material 3D printing platform for fabricating liquid crystal elastomer (LCE) lattices in both homogeneous and heterogeneous layouts with spatially programmable nematic director order and local composition is reported. Depending on their compositional topology, these lattices exhibit different reversible shape‐morphing transformations upon cycling above and below their respective nematic‐to‐isotropic transition temperatures. Further, it is shown that there is good agreement between their experimentally observed deformation response and model predictions for all LCE lattice designs evaluated. Lastly, an inverse design model is established and the ability to print LCE lattices with the predicted deformation behavior is demonstrated. This work opens new avenues for creating architected LCE lattices that may find potential application in energy‐dissipating structures, microfluidic pumping, mechanical logic, and soft robotics.

AbstractFlexible and adaptable polymer composites with high‐performance reliability over wide temperature range are imperative for various applications. However, the distinct filler‐matrix thermomechanical behaviors often cause severe structure damage and performance degradation upon large thermal shock. To address this issue, a general strategy is proposed to construct leakage‐free, self‐adaptive, stable percolation networks in polymer composites over wide temperature (77–473 K) with biphasic Ga35In65 alloy. The in situ micro‐CT technology, for the first time, reveals the conformable phase transitions of Ga35In65 alloys in the polymer matrix that help repair the disruptive conductive networks over large temperature variations. The cryo‐expanded Ga compensates the disruptive carbon networks at low temperatures, and flowable Ga and melted In at high temperatures conformably fill and repair the deboned interfaces and yielded crevices. As a proof‐of‐concept, this temperature‐resistant composite demonstrates superb electrical conductivity and electromagnetic interference shielding properties and stability even after a large temperature shock (ΔT = 396 K). Furthermore, the superiority of the construction of temperature self‐adaptive networks within the composite enables them for additive manufacturing of application‐oriented components. This work offers helpful inspiration for developing high‐performance polymer composites for extreme‐temperature applications.

AbstractPlant‐wearable sensors provide real‐time information that enables pesticide inputs to be finely tuned and play critical roles in precision agriculture. However, tracking pesticide information in living plants remains a formidable challenge owing to inadequate shape adaptabilities and low in‐field sensor sensitivities. In this study, plant‐wearable hydrogel discs are designed by embedding a dual‐shelled upconversion‐nanoparticles@zeolitic‐imidazolate‐framework@polydopamine (UCNPs@ZIF@PDA) composite in double‐network hydrogels to deliver on‐site pesticide‐residue information. Benefiting from the enzyme‐mimetic catalytic activity of ZIFs and enzyme triggered‐responsive property of PDA shell, the hydrogel discs are endowed with high sensing sensitivity toward 2,4‐dichlorophenoxyacetic acid pesticide at the nanogram per milliliter level via boosting fluorescence quenching efficiency. Notably, hydrogel discs mounted on tomato plants exhibit sufficient adaptability to profile dynamic pesticide degradation when used in conjunction with an ImageJ processing algorithm, which is practically applicable. Such hydrogel discs form a noninvasive and low‐cost toolkit for the on‐site acquisition of pesticide information, thereby contributing to the precise management of the health status of a plant and the judicious development of precision agriculture.

AbstractWide‐bandgap metal halide perovskites have demonstrated promise in multijunction photovoltaic (PV) cells. However, photoinduced phase segregation and the resultant low open‐circuit voltage (Voc) have greatly limited the PV performance of perovskite‐based multijunction devices. Here, a alloying strategy is reported to achieve uniform distribution of triple cations and halides in wide‐bandgap perovskites by doping Rb+ and Cl− with small ionic radii, which effectively suppresses halide phase segregation while promoting the homogenization of surface potential. Based on this strategy, a Voc of 1.33 V is obtained from single‐junction perovskite solar cells, and a VOC approaching 3.0 V and a power conversion efficiency of 25.0% (obtained from reverse scan direction, certified efficiency: 24.19%) on an 1.04 cm2 photoactive area can be achieved in a perovskite/perovskite/c‐Si triple‐junction tandem cell, where the certification efficiency is by far the greatest performance of perovskite‐based triple‐junction tandem solar cells. This work overcomes the performance deadlock of perovskite‐based triple‐junction tandem cells by setting a materials‐by‐design paradigm.

AbstractMultiyolk–shell (mYS) nanostructures have garnered significant interest in various photocatalysis applications such as water splitting and waste treatment. Nonetheless, the complexity and rigorous conditions for the synthesis have hindered their widespread implementation. This study presents a one‐step electrochemical strategy for synthesizing multiyolk–shell nanocoils (mYSNC), wherein multiple cores of noble metal nanoparticles, such as Au, are embedded within the hollow coil‐shaped FePO4 shell structures, mitigating the challenges posed by conventional methods. By capitalizing on the dissimilar dissolution rates of bimetallic alloy nanocoils in an electrochemically programmed solution, nanocoils of different shapes and materials, including two variations of mYSNCs are successfully fabricated. The resulting Au‐FePO4 mYSNCs exhibit exceptional photocatalytic performance for environmental remediation, demonstrating up to 99% degradation of methylene blue molecules within 50 min and 95% degradation of tetracycline within 100 min under ultraviolet–visible (UV‐vis) light source. This remarkable performance can be attributed to the abundant electrochemical active sites, internal voids facilitating efficient light harvesting with coil morphology, amplified localized surface plasmon resonance (LSPR) at the plasmonic nanoparticle‐semiconductor interface, and effective band engineering. The innovative approach utilizing bimetallic alloys demonstrates precise geometric control and design of intricate multicomponent hybrid composites, showcasing the potential for developing versatile hollow nanomaterials for catalytic applications.

AbstractCancer is one of the most life‐threatening diseases worldwide. Numerous diagnostic and therapeutic techniques, such as nanomaterials‐based cancer detection and imaging‐guided focal therapy, are successfully developed to achieve highly precise cancer theranostic strategies. However, due to unpredictive alterations occurring in cancer cell morphology, a lack of sensitivity and selectivity is a critical challenge among most biomarkers’ detection. To address this issue, instead of targeting proteins or biomarkers, the detection of cancer using whole cell‐based biosensors are ubiquitously discovered through a selective oligonucleotide, so‐called aptamer. Aptamer‐based whole‐cell detection is concurrently engaged with various nanomaterials, such as magnetic beads, gold (Au) nanoparticles, and graphene family to establish a better performance of the biosensor. In this research review, the recent strategies and prospects on whole‐cell cancer detection platform based on electrochemical aptasensors integrated with nanomaterials are thoroughly discussed and summarized. Finally, future challenges and prospects are also provided.

AbstractCurrently available guided bone regeneration (GBR) films lack active immunomodulation and sufficient osteogenic ability‐ in the treatment of periodontitis, leading to unsatisfactory treatment outcomes. Challenges remain in developing simple, rapid, and programmable manufacturing methods for constructing bioactive GBR films with tailored biofunctional compositions and microstructures. Herein, the controlled electroassembly of collagen under the salt effect is reported, which enables the construction of porous films with precisely tunable porous structures (i.e., porosity and pore size). In particular, bioactive salt species such as the anti‐inflammatory drug diclofenac sodium (DS) can induce and customize porous structures while enabling the loading of bioactive salts and their gradual release. Sequential electro‐assembly under pre‐programmed salt conditions enables the manufacture of a Janus composite film with a dense and DS‐containing porous layer capable of multiple functions in periodontitis treatment, which provides mechanical support, guides fibrous tissue growth, and acts as a barrier preventing its penetration into bone defects. The DS‐containing porous layer delivers dual bio‐signals through its morphology and the released DS, inhibiting inflammation and promoting osteogenesis. Overall, this study demonstrates the potential of electrofabrication as a customized manufacturing platform for the programmable assembly of collagen for tailored functions to adapt to specific needs in regenerative medicine.

AbstractGenerally, the low electron–hole separation efficiency of covalent organic frameworks (COFs) prevents their catalytic performance from reaching satisfactory results. For this reason, the creation of heterojunctions is considered an effective strategy but usually suffers from dimensional mismatch of the integrated material, even at the expense of its redox capacity. To overcome these difficulties, a novel 2D/2D S‐scheme heterojunction between H2N–Cu–MOF (NCM) and TpPa–1–COF (TP1C) is successfully constructed for efficient photocatalytic H2 production. The matching dimensions of two crystalline porous materials enables the integrated materials with abundant surface reactive sites, strong interaction and optimized electronic structure. Moreover, the combination of two crystalline porous materials can also form a S–scheme heterojunction, which can not only promote the separation of electron–hole pair, but also preserve the redox ability, thus remarkably boosting the catalytic competence. Consequently, the rate of optimal 20% NCM/TP1C in photocatalytic H2 production reaches 4.19 mmol g−1 h−1, which is 46.5 times higher than that of bare NCM, and 22.1 folds over that of pure TP1C. This research offers an innovative perspective for the formation of S–scheme heterojunctions based on porous crystal materials for efficient solar energy utilization.
Bioinformatics procedure for investigating senolytic (anti‐aging) agents: A digital signal processing technique
Authors: Nwankwo Norbert , Okafor Ignatius 
Published: January 2024

AbstractObjectiveCell growth involves cell division. This stops after reaching a certain limit. Some cells become inactive and unable to undergo apoptosis (programmed cell death). These cells accumulate at sites of tissue damage or disease, thus accelerating aging. They are called senescent cells. Therapeutic interventions that can either eliminate senescent cells (senolytics) or suppress their harmful effects (senomorphics) have been developed. Senescence (aging) is caused by the inter‐ and intramolecular interactions between the domains of forkhead (FHD) and transactivation (TAD), as well as C‐terminal region 3 (CR3) and DNA binding (DBD). On the other hand, anti‐senescent/senolytic (anti‐aging) activities are achieved by disrupting these interactions with CR3‐ and forkhead box protein O4 (FOXO4)‐based peptides, such as ES2 and DRI, respectively. In this study, we use a computerized procedure based on digital signal processing to systematically analyze the inter‐molecular interactions between senolytics and their targets.MethodsInformational spectrum method (ISM) is engaged.ResultsWe obtained the sequences of the peptides from the interacting proteins of CR3 and FOXO4 and evaluated their ability to disrupt the inter‐molecular interactions between FOXO4 and DRI and CR3 and BDB, which are responsible for senescence (aging). Our results show that the peptides have different degrees of senolytic (anti‐aging) activity, depending on their affinity for CR3 and BDB, or FOXO4 and DRI. We found that enhanced senescence 2 (ES2) has a higher affinity for CR3 and BDB than FOXO4 and DRI, and that the interaction between CR3 and BDB is crucial for aging. Therefore, ES2 and other CR3‐based peptides are more potent senolytics than FOXO4‐based peptides. Our findings are consistent with previous studies and reveal new insights into the mechanisms of senescence and senolytics. ES2 is considered the best senolytic candidate, as it is 3–7 times more effective than DRI. We verified that ES2 has a weaker interaction with FOXO4 than CR3. However, the performance of DRI has been noted to depend on its intramolecular interactions and stability. Hence, intramolecular analyses using the digital signal processing‐based technique has become very vital and will follow.ConclusionCR3‐based peptides are promising candidates for senolytic therapy. Senolytics are linear chains of amino acids that can target and eliminate senescent cells, which are cells that have stopped dividing and contribute to aging and age‐related diseases. By using this proposed, novel computerized technique that is based on digital signal processing, senolytics can be easily analyzed and optimized for their effectiveness and safety. This provides a more rational approach to enhancing our longevity and well‐being by offering interventions that can delay or reverse aging and insights that can advance the field of gerontology. This procedure also will compliment other approaches such as molecular stimulation, etc.

Published: January 2024

AbstractAqueous all‐iron flow batteries (AIFBs) are attractive for large‐scale and long‐term energy storage due to their extremely low cost and safety features. To accelerate commercial application, a long cyclable and reversible iron anolyte is expected to address the critical barriers, namely iron dendrite growth and hydrogen evolution reaction (HER). Herein, we report a robust iron complex with triethanolamine (TEA) and 2‐methylimidazole (MM) double ligands. By introducing two ligands into one iron center, the binding energy of the complex increases, making it more stable in the charge‐discharge reactions. The Fe(TEA)MM complex achieves reversible and stable redox between Fe3+ and Fe2+, without metallic iron growth and HER. AIFBs based on this anolyte perform a high energy efficiency of 80.5 % at 80 mA cm−2 and exhibit a record durability among reported AIFBs. The efficiency and capacity retain nearly 100 % after 1,400 cycles. The capital cost of this AIFB is $ 33.2 kWh−1 (e.g., 20 h duration), cheaper than Li‐ion battery and vanadium flow battery. This double‐ligand chelating strategy not only solves the current problems faced by AIFBs, but also provides an insight for further improving the cycling stability of other flow batteries.
Photoredox‐Catalyzed Generation of Tertiary Anions from Primary Amines via a Radical Polar Crossover
Authors: Marchese Austin D. , Dorsheimer Julia R. , Rovis Tomislav 
Published: January 2024

AbstractA method for the generation of tertiary carbanions via a deaminative radical‐polar crossover is reported using redox active imines from α‐tertiary primary amines. A variety of benzylic amines and amino esters can be used in this approach, with the latter engaging in a novel “aza‐Reformatsky” reaction. Electronic trends correlate the stability of the resulting carbanion with reaction efficiency. The anions can be trapped with different electrophiles including aldehydes, ketones, imines, Michael acceptors, and H2O/D2O. Selective anion formation can be achieved in the presence of another equivalent or more acidic C−H bond in both an inter‐ and intramolecular fashion. Mechanistic studies suggest the intermediacy of a discrete carbanion intermediate.

AbstractAn iridium‐conjoined long and narrow metallorectangle was obtained by combining a quinoxalinophenanthrophenazine‐connected Janus‐di‐imidazolylidene ligand and pyrazine. The size and shape of this assembly together with the fused polyaromatic nature of its panels provides it with properties that are uncommon for other metallosupramolecular assemblies. For example, this nanosized ‘slit‐like’ metallobox is able show very large binding affinities with planar organic molecules in such a way, that the cavity is asymmetrically occupied by the guest molecule. This unsymmetrical conformation leads to the existence of a large amplitude motion of these guests, which slide between the two sides of the cavity of the host, thus constituting rare examples of molecular shuttles.

AbstractCatalysts involving post‐transition metals have shown almost invincible performance on generating formate in electrochemical CO2 reduction reaction (CO2RR). Conversely, Cu without post‐transition metals has struggled to achieve comparable activity. In this study, a sulfur (S)‐doped‐copper (Cu)‐based catalyst is developed, exhibiting excellent performance in formate generation with a maximum Faradaic efficiency of 92 % and a partial current density of 321 mA cm−2. Ex situ structural elucidations reveal the presence of abundant grain boundaries and high retention of S−S bonds from the covellite phase during CO2RR. Furthermore, thermodynamic calculations demonstrate that S−S bonds can moderate the binding energies with various intermediates, further improving the activity of the formate pathway. This work is significant in modifying a low‐cost catalyst (Cu) with a non‐metallic element (S) to achieve comparable performance to mainstream catalysts for formate generation in industrial grade.

AbstractMolecular emitters with multi‐emissive properties are in high demand in numerous fields, while these properties basically depend on specific molecular conformation and packing. For amorphous systems, special molecular arrangement is unnecessary, but it remains challenging to achieve such luminescent behaviors. Herein, we present a general strategy that takes advantage of molecular rigidity and S1‐T1 energy gap balance for emitter design, which enables fluorescence–phosphorescence dual‐emission properties in various solid forms, whether crystalline or amorphous. Subsequently, the amorphism of the emitters based polymethyl methacrylate films endowed an in situ regulation of the dual‐emissive characteristics. With the ratiometric regulation of phosphorescence by external stimuli and stable fluorescence as internal reference, highly controllable luminescent color tuning (yellow to blue including white emission) was achieved. There properties together with a persistent luminous behavior is of benefit for an irreplaceable set of optical information combination, featuring an ultrahigh‐security anti‐counterfeiting ability. Our research introduces a concept of eliminating the crystal‐form and molecular‐conformational dependence of complex luminescent properties through emitter molecular design. This has profound implications for the development of functional materials.
