Authors: Liu Wenqiang , Hu Chunhong , Hu Qingying , Liu Wei , Ren Wang 
Published: September 2023

SummaryThis article investigates the robust steady‐state matrix‐weighted fusion (MWF) filtering problem for multisensor multichannel autoregressive (AR) signal with multiple uncertainties, which can be transformed into the state estimation problems in the state space representation. The uncertainties include the random parameter matrices, uncertain noise variances (UNVs), one‐step random measurement delay, missing measurements, and packet dropouts. Three Bernoulli distributed stochastic variables with known conditional probabilities are introduced to describe the networked stochastic uncertainties. The AR signal model under consideration is transformed into a state space model only with UNVs via using a combined method, which is composed of the state space method, the augmented method, and the fictitious noise method. Based on the worst‐case system with conservative upper bounds of UNVs, the robust local steady‐state one‐step and multi‐step signal predictors are proposed by using the minimax robust estimation method. Subsequently, the distributed fusion signal predictors weighted by matrices are addressed. The robustness of the proposed signal predictors is proved by the introduced augmented noises and permutation matrices. Simulation experiment demonstrates the correctness and effectiveness of the proposed methods.

AbstractCombination immunotherapy has emerged as a promising strategy to address the challenges associated with immune checkpoint inhibitor (ICI) therapy in breast cancer. The efficacy of combination immunotherapy hinges upon the intricate and dynamic nature of the tumor microenvironment (TME), characterized by cellular heterogeneity and molecular gradients. However, current methodologies for drug screening often fail to accurately replicate these complex conditions, resulting in limited predictive capacity for treatment outcomes. Here, a tumor‐microenvironment‐on‐chip (TMoC), integrating a circulation system and ex vivo tissue culture with physiological oxygen and nutrient gradients, is described. This platform enables spatial infiltration of cytotoxic CD8+ T cells and their targeted attack on the tumor, while preserving the high complexity and heterogeneity of the TME. The TMoC is employed to assess the synergistic effect of five targeted therapy drugs and five chemotherapy drugs in combination with immunotherapy, demonstrating strong concordance between chip and animal model responses. The TMoC holds significant potential for advancing drug development and guiding clinical decision‐making, as it offers valuable insights into the complex dynamics of the TME.

AbstractA novel, zero‐waste and recycling plastic waste solution is introduced, to scalably produce graphene nanoplatelets/barium titanate (GNP/BaTiO3) polymer nanocomposite fibrils. A comprehensive investigation is performed to evaluate the compatible and non‐compatible recycled polypropylene (PP)/polyethyleneterephthalate (PET) blends combined with functional (electrical, piezoelectric,and dielectric) materials for in‐situ fibril production. The nanocompositefibrils made from recycled PP, PET and GNPs/BaTiO3 with high‐aspect ratio disparity (400:1) are produced, which exhibit significantly enhanced electrical, thermomechanical, and electromagnetic characteristics. Single‐screw extrusion is utilised to fabricate the fibrils with the in‐situ fibril morphology of PET and GNPs/BaTiO3 leading to improved electrical conductivity. It is demonstrated that such fibril morphology restricts the chain mobility of polymer molecules, and ultimately increases viscosity and strain energy. Moreover, the study demonstrates a positive reinforcement effect from the utilisation of PET fibrils and GNPs/BaTiO3 in a PP matrix, dominated by the high‐aspect ratio, stiffness, and thermal stability of GNPs/BaTiO3. Furthermore, it is observed that the mechanical properties and tension‐bearing capacity of the PP are significantly improved by such incorporation. The study also demonstrates that the protection of the remanufactured nanocomposites against electromagnetic interference is significantly improved with the increasing GNPs/BaTiO3 content and the morphological transition from spherical to fibril‐shaped PET.

AbstractThe versatility of the spinel (AB2O4) oxides means they are of great interest for a variety of catalysis and energy conversion applications, involving gas reactions and reforming. CuFe2O4 spinel is identified as a highly efficient fuel electrode for CO2/H2O co‐electrolysis due to its promising electrocatalytic activity. To identify the actual active sites, the electrochemical characteristics, composition, chemical state, and microstructure are systematically investigated while optimizing the electrolysis performance by varying the feed gas composition. Markedly enhanced electrolysis current density is achieved under a CO2‐enriched composition of 50%CO2/10%H2O‐Ar. This promising performance is attributed to the in situ exsolution of heterostructural “Cu/Fe3O4” nanoparticles on the parent CuFe2O4 surface during co‐electrolysis. Interestingly, a strong correlation of the electrolysis performance with the amount of the formed heterostructural cermet is observed. The exsolved cermet heterostructure plays a crucial role in CO2/H2O electroreduction, as also confirmed by density‐functional‐theory studies. The self‐exsolved Cu/Fe3O4 nanoparticles present exceptional strength due to a strong interaction between the formed metallic Cu and Fe3O4, enabling the electrode to remain active and stable under such high electrical polarization. The excellent durability and stability of the self‐exsolved heterostructural nanoparticles are clearly confirmed by long‐term operation at high‐working voltage with an outstanding Faradaic efficiency (nearly 100%).

AbstractWith the rapidly increasing demand for grid‐scale energy storage systems, rechargeable aqueous zinc ion batteries (ZIBs) are capturing attention as a highly promising technology with low cost and high safety. Nevertheless, rampant dendrite growth, hydrogen evolution reaction (HER), and corrosion of the zinc anode have dramatically impacted their practical application. Here, a self‐supported modified layer with ultrafine high‐entropy nanoparticles (2 nm) as the zincophilic sites is realized to modify the Zn anode for the first time. High‐entropy materials with unique continuously distributed potential gaps significantly reduce the activation energy of multi‐electron reactions and modulate ion transport during zinc deposition. Moreover, thanks to the hydrophobic properties and effective desolventizing ability of the ultrafine high‐entropy nanomaterial, the unfavorable side reactions of the zinc anode are prevented to promote the zinc deposition process. As a result, stable cycling of 3500 h at 1 mA cm−2 and 600 h at a high current density of 10 mA cm−2 is achieved. Coin cells and flexible pouch cells assembled with KMO and NH4V4O10 cathodes also demonstrate promoted electrochemical performance. The dual effects of accelerating and homogenizing mechanisms in high‐entropy materials provide a new strategy for stabilizing zinc metal anodes.

AbstractConventional Li‐ion batteries equipped with graphite anodes suffer from poor rate performance and the risk of lithium dendrites, which constrain scale‐up applications. Among the promising candidates, spinel‐type Li4Ti5O12 is still subjected to low theoretical specific capacity, high working potential, and poor diffusion properties. Herein the KxNayH(2‐x‐y)Ti2O5 product is provided by reconstructing the chemical bonding idea, which exhibits enhanced specific capacity (323 mAh g−1), lower working potential (major capacity contribution < 1.5 V vs Li+/Li), higher diffusion coefficient (10−8.5–10−5 cm2 s−1), and long cycle stability. Further in/ex situ studies show that these excellent properties can be attributed to the combination of high capacitive contribution, unique “switching mechanism” to avoid lithium dendrite generation, and the zero‐strain properties. The findings provide new ideas and opportunities for the development of next generation titanate anode materials with desirable electrochemical properties.

AbstractAll solid‐state batteries are promising, as they are expected to offer increased energy density over conventional lithium‐ion batteries. Here, the microstructure of solid composite electrodes plays a crucial role in determining the characteristics of ionic and electronic pathways. Microstructural aspects that impede charge carrier transport can, for instance, be voids resulting from a general mismatch of particle sizes. Solid electrolyte materials with smaller particle size distribution represent a promising approach to limit the formation of voids and to match the smaller active materials. Therefore, a systematic investigation on the influence of the solid electrolyte particle size on the microstructural properties, charge carrier transport, and rate performance is essential. This study provides an understanding of the influence of the particle sizes of Li6PS5Cl on the charge carrier transport properties and their effect on the performance of solid‐state batteries. In conclusion, smaller Li6PS5Cl particles optimize the charge transport properties and offer a higher interface area with the active material, resulting in improved solid‐state battery performance.

AbstractUrea electrolysis can convert urea from urea‐rich wastewater to hydrogen for environmental protection and sustainable energy production. However, the sluggish kinetics of urea oxidation reaction (UOR) requires valence‐variable sites that are generally active at high anodic overpotentials. Herein, a robust ceramic coating is constructed with coupled tungsten nitride (WN)/nickel carbide (Ni3C) nanoparticles to achieve valence‐stable catalytic sites with outstanding UOR performance. Various characterization results indicate strong interfacial electron transfer from WN to Ni3C in coupled nanoparticles, which enables reservation of Ni2+ sites without self‐oxidation during UOR, quite distinct from the kinetically slow Ni3+OOH‐catalyzed UOR pathway. Theoretical calculations show that the coupled effect in WN/Ni3C leads to enhanced electron transfer from catalytic sites to adsorbed urea, and W sites are thermodynamically favorable for UOR. This efficiently lowers the barrier of rate‐determining step (RDS: *CO‐N2 → *CO·OH), thus enabling fast UOR kinetics and a low potential of 1.336 V at 100 mA cm−2, which identifies this ceramic coating as one of the best UOR electrocatalysts. This work opens a new avenue for design of stable and active sites in ceramics coatings toward advanced electrocatalytic applications.
Large‐scale chiral spherulites with controllable circularly polarized luminescence in liquid crystal block copolymers film
Authors: Yuan Jianan , Lu Xuemin , Lu Qinghua 
Published: September 2023

AbstractMacroscopic chiral spherulites prepared by hierarchical self‐assembly have attracted considerable attention due to their excellent property as chiroptical materials. However, preparing controllable chiral spherulites in bulk film remains a challenge due to the absent knowledge of the evolution mechanism from the molecule to macroscopic crystal during chiral assembly. In this contribution, chiral macroscopic spherulites were constructed with controllable circularly polarized luminescence (CPL) using enantiomeric tartaric acid and rhodamine B co‐assembled with liquid crystal block copolymers, poly(ethylene oxide)‐b‐poly(methyl methacrylate) bearing azobenzene group side chains. It was found that the chiral liquid crystal field induced by exogenous chiral molecules was closely related to the formation of macroscopic chiral spherulites. Moreover, the transformation of azobenzene cis‐trans isomerization under photo‐thermal endows films with adjustable CPL. This facile strategy provides a platform to design large‐scale chiral structures for chiroptical switching, encryption, and memory storage materials.

Published: September 2023

AbstractPremiseSpecies delimitation is an integral part of evolution and ecology and is vital in conservation science. However, in some groups, species delimitation is difficult, especially where ancestral relationships inferred from morphological or genetic characters are discordant, possibly due to a complicated demographic history (e.g., recent divergences between lineages). Modern genetic techniques can take into account complex histories to distinguish species at a reasonable cost and are increasingly used in numerous applications. We focus on the scribbly gums, a group of up to five closely related and morphologically similar “species” within the eucalypts.MethodsMultiple populations of each recognized scribbly gum species were sampled over a wide region across climates, and genomewide scans were used to resolve species boundaries.ResultsNone of the taxa were completely divergent, and there were two genetically distinct entities: the inland distributedEucalyptus rossiiand a coastal conglomerate consisting of four species forming three discernible, but highly admixed groups. Divergence among taxa was likely driven by temporal vicariant processes resulting in partial separation across biogeographic barriers. High interspecific gene flow indicated separated taxa reconnected at different points in time, blurring species boundaries.ConclusionsOur results highlight the need for genetic screening when dealing with closely related taxonomic entities, particularly those with modest morphological differences. We show that high‐throughput sequencing can be effective at identifying species groupings and processes driving divergence, even in the most taxonomically complex groups, and be used as a standard practice for disentangling species complexes.
Fatal injuries associated with rear step riding among municipal solid waste collection workers (United States, 1984–2020)
Authors: Zhu Julia , Fletcher Alicia , Verma Nehel 
Published: September 2023

AbstractBackgroundUnited States solid waste workers suffer a high fatal injury rate due to their frequent exposures to refuse‐vehicle‐related hazards. The Occupational Safety and Health Administration (OSHA) allows workers to ride on the rear steps of a garbage truck (exterior riding) if employers abide by American National Standard Z245.1 (ANSI Z245.1). The State of California (CA) has banned exterior riding since 1984, and the City of New York (NYC) has implemented its own initiatives to prevent exterior riding deaths.MethodsFatal exterior riding incidents were identified from two online databases. Variables relating to deceased workers, employers, and injury circumstances were analyzed.ResultsThe study identified 181 exterior riding deaths from 604 refuse‐vehicle‐related fatal incidents (deaths either directly caused by a refuse vehicle or one in which the victim was performing a refuse‐vehicle‐related task) in the United States (1984–2020). A total of 50 (27.6%) of the exterior riding deaths had no ANSI Z245.1 violations. Risk factors other than those addressed by ANSI Z245.1 contributed to these worker deaths.ConclusionsExterior riding deaths identified by this study were all preventable. Temporary workers and workers in the public sector may be at higher risk for exterior riding deaths. Both CA and NYC had taken measures to prohibit the practice of exterior riding, and both had lower numbers of exterior riding deaths. ANSI Z245.1 and current OSHA enforcement policy do not address the inherent dangers of falling off a moving heavy vehicle while standing on a small and elevated platform, and are not effective in preventing fatal exterior riding incidents.

AbstractBackgroundFrailty is prevalent among older adults with asthma or chronic obstructive pulmonary disease (obstructive lung diseases [OLDs]). Frailty and OLD's co‐occurrence is associated with increased hospitalization/mortality. Chemosensory dysfunction is closely connected to both OLD and frailty. We evaluated the utility of olfactory decline as a biomarker of frailty in the setting of OLD.MethodsWe performed a prospective, longitudinal, nationally representative study of community‐dwelling older US adults in the National Social Life, Health and Aging Project, an omnibus in‐home survey. Respondents reported a physician's diagnosis of OLD. Decline in odor identification and sensitivity over 5 years and frailty (adapted fried frailty phenotype criteria) were measured using standard tools. Multivariate logistic regressions evaluated the association between OLD status, olfactory decline, and frailty.ResultsWe compared individuals with OLD (n = 98; mean age 71.2 years, 59.2% women) and those without OLD (n = 1036; mean age 69.5 years, 58.9% women). Olfactory identification decline was associated with developing frailty over the 5‐year follow‐up period in individuals with OLD (odds ratio [OR] = 9.1, 95% confidence interval [CI] = 2.1–38.6, p = 0.003). Olfactory decline predicted incidence of frailty in individuals with OLD (identification: OR = 4.8, 95% CI = 1.3–17.5, P = 0.018; sensitivity: OR = 6.1, 95%CI = 1.2–31.0, p = 0.030) but not in those without OLD adjusting for demographics, heavy alcohol use, current smoking, and comorbidity. Results were robust to different thresholds for olfactory decline and frailty development.ConclusionsOlder adults with OLD who experience olfactory decline face higher odds of developing frailty. Use of olfactory decline as a biomarker to identify frailty could allow earlier intervention and decrease adverse outcomes for high‐risk older adults with OLD.

AbstractIdentifying (bio)catalysts displaying high enantio‐/stereoselectivity is a fundamental prerequisite for the advancement of asymmetric catalysis. Herein, a high‐throughput, stereoselective screening assay is reported that gives information on enantioselectivity, stereopreference and activity as showcased for peroxygenase‐catalyzed hydroxylation. The assay is based on spectrophotometric analysis of the simultaneous formation of NAD(P)H from the alcohol dehydrogenase catalyzed enantioselective oxidation of the sec‐alcohol product formed in the peroxygenase reaction. The assay was applied to investigate a library comprising 44 unspecific peroxygenases (UPOs) containing 25 UPOs not reported yet. Thereby, previously non‐described wild‐type UPOs displaying (S)‐ as well as (R)‐stereoselectivity for the hydroxylation of representative model substrates were identified, reaching up to 98 % ee for the (R)‐ and 94 % ee for the (S)‐enantiomer. Homology models with concomitant docking studies indicated the structural reason for the observed complementary stereopreference.

AbstractEco‐friendly lead‐free organic–inorganic manganese halides (OIMHs) have attracted considerable attention in various optoelectronic applications because of their superior optical properties and flexible solution processibility. Herein, we report a novel pseudo‐2D layered OIMH (MTP)2MnBr4 (MTP: methyltriphenylphosphonium), which exhibits intense green emission under UV/blue or X‐ray excitation, with a near‐unity photoluminescence quantum yield, high resistance to thermal quenching (I150 °C=84.1 %) and good photochemical stability. These features enable (MTP)2MnBr4 as an efficient green phosphor for blue‐converted white light‐emitting diodes, demonstrating a commercial‐level luminous efficiency of 101 lm W−1 and a wide color gamut of 116 % NTSC. Moreover, these (MTP)2MnBr4 crystals showcase outstanding X‐ray scintillation properties, delivering a light yield of 67000 photon MeV−1, a detection limit of 82.4 nGy s−1, and a competitive spatial resolution of 6.2 lp mm−1 for X‐ray imaging. This work presents a new avenue for the exploration of eco‐friendly luminescent OIMHs towards multifunctional light‐emitting applications.
