ObjectiveCognitive impairment (CI) in systemic lupus erythematosus (SLE) negatively impacts health‐related quality of life leading to activity limitations. This qualitative study aimed to (1) explore the effect of SLE‐related CI on activities of daily living and life role participation and (2) describe factors influencing activity restriction and life role participation.MethodsSemistructured, in‐depth interviews of lived experience of CI in SLE were conducted with 24 participants with SLE. Sociodemographic and clinical data, and objective and subjective cognitive function, were collected to characterize participants. A qualitative thematic content analysis was undertaken guided by a framework analytical approach.ResultsParticipants reported problems in multiple cognitive domains, with multiple perceived causes. CI was felt to impact work, social, domestic, and family life, health, and independence. Five overarching themes were represented in the data: (1) characterization of SLE‐reported CI, (2) perceived cause of CI, (3) perceived impact of CI on activities of daily living and life role participation, (4) adaptations for managing CI, and (5) influence of CI adaptations on activities of daily living and life role participation.ConclusionThis study provides a better understanding of the patient experience of CI in SLE, how it impacts their lives, and what coping strategies they employ. It highlights the long‐term challenges those with CI in SLE undergo and provides evidence for the urgent need to implement multidisciplinary treatment options. When managing CI, it may be beneficial to evaluate and understand available psychosocial support resources to help identify and reinforce relevant adaptations to improve health‐related quality of life.
Finite‐time optimal control for uncertain strict‐feedback nonlinear systems with input saturation and output constraints
Authors: Xia Xiaonan , Li Chun , Zhang Tianping , Fang Yu 
Published: November 2023

SummaryIn this paper, a finite‐time optimal control (FTOC) strategy is proposed for output constrained uncertain nonlinear systems with input saturation. The controller adopts a feed‐forward and optimal feedback control structure. The second‐order command filter and the auxiliary error compensation system are designed in the feed‐forward controller, which can eliminate the influence of filtering error on system performance while avoiding the singularity problem of finite‐time control. A new critic weight updating law is proposed in the design of the optimal feedback controller, in which a neural network is utilized to approximate the relevant cost function. The control scheme can ensure that all signals in the optimize system are semi‐global practical finite‐time stable (SGPFS), and the cost function is also minimized. The effectiveness of the algorithm is validated through simulation examples.

Published: November 2023

AbstractTopological solitons are currently under investigation for their exotic properties, especially in nonlinear physics, optics, and material sciences. However, challenges of robust generation and limited stability over time have hindered their practical uses. To address this issue, an approach is developed to form structured arrays of solitons in films of polymerizable liquid crystals. Their complex molecular architecture is preserved by in situ photopolymerization forming a stable liquid crystal network. Most excitingly, their properties are advanced to include responsiveness functions. When thermally actuated, these topological solitons mediate the reconfiguration of surface topographies. Complex shape changes occur depending on the intrinsic complex spatial distribution of the director, which may even lead to full shape inversion and topographical changes as high as ≈40% of the initial thickness. Conversely, the shape changes provide information on the initial director profile, which is consistent with the mathematical model. The soliton‐containing polymer coatings are applicable in multiple domains, ranging from tunable optics to haptics, and from shape‐coupled sensing systems to temperature‐coupled heat management.

AbstractBattery‐sensing‐based all‐in‐one pressure sensors are generally successfully constructed by mimicking the information transfer of living organisms and the sensing behavior of human skin, possessing features such as low energy consumption and detection of low/high‐frequency mechanical signals. To design high‐performance all‐in‐one pressure sensors, a deeper understanding of the intrinsic mechanisms of such sensors is required. Here, a mechanical–electrical conversion mechanism based on pressure‐modulated nanoconfined channels is proposed. Then, the mechanism of ion accelerated transport in graphene oxide (GO) nanoconfined channels under pressure is revealed by density functional theory (DFT) calculation. Based on this mechanism, a proton battery‐type self‐powered pressure sensor MoO3/GO[CNF/Ca]/activated carbon (AC) is designed with an open‐circuit voltage stabilization of 0.648 V, an ultrafast response/recovery time of 86.0 ms/93.0 ms, pressure detection ranges of up to 60.0 kPa, and excellent static/dynamic pressure response. In addition, the one‐piece device design enables self‐supply, miniaturization, and charge/discharge reuse, showing application potential in wearable electronics, health monitoring, and other fields.

AbstractCu‐based perovskites have excellent optical properties, environmental friendliness, and broad optical applications. However, their development is hindered by complex preparation methods and poor hydrochromic stability. In this work, a solvent‐evaporation‐based crystallization strategy combined with Sn doping for the preparation of Cs3Cu2I5 microcrystals (MCs) is reported. This strategy enhances the photoluminescence quantum yield (PLQY) and hydrochromic reliability. In addition, first‐principles calculations reveal the effect of Sn doping on the lattice structure and exciton–phonon coupling of the Cs3Cu2I5 MCs. The results show that Sn doping reduces the lattice spacing as a result of the substitution radius difference between Cu+ and Sn2+ ions, which causes stronger exciton–phonon coupling and enhances the PLQY. Moreover, the Sn‐doped Cs3Cu2I5 MCs show excellent reliability on heating and under hydrochromic cycles and long‐term luminescence conditions. Based on their hydrochromic and temperature‐responsive properties, the Sn‐doped Cs3Cu2I5 MCs are applied as encryptable printing materials for information encryption and decryption and as a fluorescence‐based temperature sensor, combined with Machine‐Learning to guide the manufacturing of fluorescent thermometers. The findings provide insights into the commercial value of copper‐based perovskites and demonstrate their potential anti‐counterfeiting, fluorescence temperature sensing applications.

AbstractChiral molecules play important roles in advanced materials and technologies owing to their unique chiroptical properties. How to design and construct the best chiral molecules with intrinsically strong chiroptical properties is still a great challenge since there is an intrinsic contradiction between the large absorption dissymmetry factor and oscillator strength. In this work, through a systematic theoretical investigation, it is found that chiral cylindrical molecules could overcome this problem through accumulating the electric and magnetic transition dipole moment along the cylindrical axis direction while canceling them in other directions. Among all the investigated structures, (M)‐[8]CC2,8 is found to exhibit the best chiroptical properties with gabs of 0.71 and oscillator strength of 0.032. To the best of our knowledge, this is the best chiral molecule with both large dissymmetry factor and oscillator strength. Further increasing the repeating units, the gabs can even reach the theoretical limit of 2 for (M)‐[28]CC2,8, together with a large oscillator strength of 0.134. The result offers the exciting opportunities for designing and synthesizing chiral materials with truly large intrinsically chiroptical properties toward real applications in chiroptoelectronic and chiro‐spintronic devices.

AbstractThe essential branched‐chain amino acids (BCAAs) leucine, isoleucine, and valine play critical roles in protein synthesis and energy metabolism. Despite their widespread use as nutritional supplements, BCAAs’ full effects on mammalian physiology remain uncertain due to the complexities of BCAA metabolic regulation. Here a novel mechanism linking intrinsic alterations in BCAA metabolism is identified to cellular senescence and the senescence‐associated secretory phenotype (SASP), both of which contribute to organismal aging and inflammation‐related diseases. Altered BCAA metabolism driving the SASP is mediated by robust activation of the BCAA transporters Solute Carrier Family 6 Members 14 and 15 as well as downregulation of the catabolic enzyme BCAA transaminase 1 during onset of cellular senescence, leading to highly elevated intracellular BCAA levels in senescent cells. This, in turn, activates the mammalian target of rapamycin complex 1 (mTORC1) to establish the full SASP program. TransgenicDrosophilamodels further indicate that orthologous BCAA regulators are involved in the induction of cellular senescence and age‐related phenotypes in flies, suggesting evolutionary conservation of this metabolic pathway during aging. Finally, experimentally blocking BCAA accumulation attenuates the inflammatory response in a mouse senescence model, highlighting the therapeutic potential of modulating BCAA metabolism for the treatment of age‐related and inflammatory diseases.

Published: November 2023

AbstractThe inferior capacity and cyclic durability of V2O5 caused by inadequate active sites and sluggish kinetics are the main problems to encumber the widespread industrial applications of vanadium‐zinc batteries (VZBs). Herein, a cooperative redox chemistry (CRC) as “electron carrier” is proposed to facilitate the electron‐transfer by capturing/providing electrons for the redox of V2O5. The increased oxygen vacancies in V2O5 provoked in situ by CRC offers numerous Zn2+ storage sites and ion‐diffusion paths and reduces the electrostatic interactions between vanadium‐based cathode and intercalated Zn2+, which enhance Zn2+ storage capability and structural stability. The feasibility of this strategy is fully verified by some CRCs. Noticeably, VZB with [Fe(CN)6]3−/[Fe(CN)6]4− as CRC displays conspicuous specific capacity (433.3 mAh g−1), ≈100% coulombic efficiency and superb cyclability (≈3500 cycles without capacity attenuation). Also, the mechanism and selection criteria of CRC are specifically unraveled in this work, which provides insightful perspectives for the development of high‐efficiency energy‐storage devices.

AbstractThin and flexible materials that can provide efficient electromagnetic interference (EMI) shielding are urgently needed, particularly those that can be rapidly processed and withstand harsh environments. Cobalt‐based metallic glasses stand out as prime candidates due to their excellent soft magnetic properties, satisfactory shielding features, and mechanical properties. Herein, a recently developed technique is used to fabricate metallic glass microfibers from Co66Fe4Mo2Si16B12 alloy. The produced microfibers are characterized for their size and uniformity by scanning electron microscopy and their amorphous structure is confirmed by X‐ray diffraction (XRD) and differential scanning calorimetry (DSC). The cobalt‐based metallic glass microfibers show an EMI shielding factor that reaches five in the static regime and obtains an up to 25‐fold increase of the attenuation constant in the Ku frequency band. This performance originates from the combination of soft magnetic properties and excellent electrical conductivity. In addition, the flexible microfibers exhibit excellent hardness and elasticity making them suitable for EMI shielding of complex geometries. Their hardness and elastic modulus are measured by nanoindentation to be 11.31 ± 0.60 GPa, and 110.54 ± 11.24 GPa, respectively.

AbstractDue to their sequence‐directed functions and excellent biocompatibility, smart DNA microgels have attracted considerable research interest, and the combination of DNA microgels with functional nanostructures can further expand their applications in biosensing and biomedicine. Gallium‐based liquid metals (LMs) exhibiting both fluidic and metallic properties hold great promise for the development of smart soft materials; in particular, LM particles upon sonication can mediate radical‐initiated polymerization reactions, thus allowing the combination of LMs and polymeric matrix to construct “soft–soft” materials. Herein, by forming active surfaces under sonication, LM nanoparticles (LM NPs) initiated localized radical polymerization reactions allow the combination of functional DNA units and different polymeric backbones to yield multifunctional core/shell microgels. The localized polymerization reaction allows fine control of the microgel compositions, and smart DNA microgels with tunable catalytic activities can be constructed. Moreover, due to the excellent photothermal effect of LM NPs, the resulting temperature gradient between microgels and surrounding solution upon NIR light irradiation can drive the oriented locomotion of the microgels, and remote control of the activity of these smart microgels can be achieved. These microgels may hold promise for various applications, such as the development of in vivo and in vitro biosensing and drug delivery systems.

AbstractIn nature and technologies, many chemical reactions occur at interfaces with dimensions approaching that of a single reacting species in nano‐ and angstrom‐scale. Mechanisms governing reactions at this ultimately small spatial regime remain poorly explored because of challenges to controllably fabricate required devices and assess their performance in experiment. Here we report how efficiency of electrochemical reactions evolves for electrodes that range from just one atom in thickness to sizes comparable with and exceeding hydration diameters of reactant species. The electrodes are made by encapsulating graphene and its multilayers within insulating crystals so that only graphene edges remain exposed and partake in reactions. We find that limiting current densities characterizing electrochemical reactions exhibit a pronounced size effect if reactant's hydration diameter becomes commensurable with electrodes’ thickness. An unexpected blockade effect is further revealed from electrodes smaller than reactants, where incoming reactants are blocked by those adsorbed temporarily at the atomically narrow interfaces. The demonstrated angstrom‐scale electrochemistry offers a venue for studies of interfacial behaviors at the true molecular scale.

AbstractValanimycin is an azoxy‐containing natural product isolated from the fermentation broth of Streptomyces viridifaciens MG456‐hF10. While the biosynthesis of valanimycin has been partially characterized, how the azoxy group is constructed remains obscure. Herein, the membrane protein VlmO and the putative hydrazine synthetase ForJ from the formycin biosynthetic pathway are demonstrated to catalyze N−N bond formation converting O‐(l‐seryl)‐isobutyl hydroxylamine into N‐(isobutylamino)‐l‐serine. Subsequent installation of the azoxy group is shown to be catalyzed by the non‐heme diiron enzyme VlmB in a reaction in which the N−N single bond in the VlmO/ForJ product is oxidized by four electrons to yield the azoxy group. The catalytic cycle of VlmB appears to begin with a resting μ‐oxo diferric complex in VlmB, as supported by Mössbauer spectroscopy. This study also identifies N‐(isobutylamino)‐d‐serine as an alternative substrate for VlmB leading to two azoxy regioisomers. The reactions catalyzed by the kinase VlmJ and the lyase VlmK during the final steps of valanimycin biosynthesis are established as well. The biosynthesis of valanimycin was thus fully reconstituted in vitro using the enzymes VlmO/ForJ, VlmB, VlmJ and VlmK. Importantly, the VlmB‐catalyzed reaction represents the first example of enzyme‐catalyzed azoxy formation and is expected to proceed by an atypical mechanism.

AbstractThe achievement of significant photoluminescence (PL) in lanthanide ions (Ln3+) has primarily relied on host sensitization, where energy is transferred from the excited host material to the Ln3+ ions. However, this luminous mechanism involves only one optical antenna, namely the host material, which limits the accessibility of excitation wavelength‐dependent (Ex‐De) PL. Consequently, the wider application of Ln3+ ions in light‐emitting devices is hindered. In this study, we present an organic–inorganic compound, (DMA)4LnCl7 (DMA+=[CH3NH2CH3]+, Ln3+=Ce3+, Tb3+), which serves as an independent host lattice material for efficient Ex‐De emission by doping it with trivalent antimony (Sb3+). The pristine (DMA)4LnCl7 compounds exhibit high luminescence, maintaining the characteristic sharp emission bands of Ln3+ and demonstrating a high PL quantum yield of 90–100 %. Upon Sb3+ doping, the compound exhibits noticeable Ex‐De emission with switchable colors. Through a detailed spectral study, we observe that the prominent energy transfer process observed in traditional host‐sensitized systems is absent in these materials. Instead, they exhibit two independent emission centers from Ln3+ and Sb3+, each displaying distinct features in luminous color and radiative lifetime. These findings open up new possibilities for designing Ex‐De emitters based on Ln3+ ions.

AbstractConjugated linoleic acid (CLA) has a variety of health‐promoting biological activities, and thus has a great potential as dietary supplement in functional foods. In our work, the effects of surface modifications of multiwalled carbon nanotubes (MWCNTs) support on the catalytic efficiency and selectivity of supported Ru catalysts for linoleic acid (LA) to CLA, as well as their influence mechanisms were well investigated. The results showed that the CLA yields for Ru/MWCNTs‐OH (36.45%) and Ru/MWCNTs‐COOH (31.06%) were significantly higher than that for Ru/MWCNTs (23.94%). This indicated that hydroxylated and carboxylated surface modification of MWCNTs could improve the catalytic activity of Ru. The CLA selectivity of Ru/MWCNTs‐N‐Doped and Ru/MWCNTs‐NH2 were up to 96.06% and 88.26%, respectively, and was also proved to be temperature and time dependent. TEM analysis indicated Ru nanoparticles were evenly attached on the surface of mMWCNTs but have little agglomeration on MWCNTs, and their particle sizes are negatively related to the catalytic efficiency. Further catalyst characterization by XPS demonstrated that high CLA selectivity of Ru/MWCNTs‐N‐Doped and Ru/MWCNTs‐NH2 were attributed to the high Ru (IV) content on the surface of supports. Thus, the mMWCNTs were proved to be the excellent support of Ru catalyst for high isomerization selectivity towards CLA formation.
