AbstractThe development of an efficient fabrication route to achieve high‐resolution perovskite pixel array is key for large‐scale flexible image sensor devices. Herein, a high‐resolution and stable 10 × 10 flexible PDs array based on formamidinium(FA+) and phenylmethylammonium (PMA+) quasi‐2D (PMA)2FAPb2I7 (n = 2) perovskite is demonstrated by developing SiO2‐assisted hydrophobic and hydrophilic treatment process on polyethylene terephthalate substrate. By introducing Au nanoparticles (Au NPs), the perovskite film quality is improved and grain boundaries are reduced. The mechanism by which Au NPs upgrade the photoelectric quality of perovskite is mainly revealed by glow discharge‐optical emission spectroscopy (GD‐OES) and grazing‐incidence wide‐angle X‐ray scattering (GIWAXS). To further improve the photoelectric performance of the devices, a post‐treatment strategy with formamidinium chloride (FACl) is used . The optimized flexible PDs arrays show excellent optoelectronic properties with a high responsivity of 4.7 A W−1, a detectivity of 6.3 × 1012 Jones, and a broad spectral sensitivity. The device also exhibits excellent electrical stability even under severe bending and excellent flexural strength, as well as excellent environmental stability. Finally, the integrated flexible PDs arrays are used as sensor pixels in an imaging system to obtain high‐resolution imaging patterns, demonstrating the imaging capability of the PDs arrays.

AbstractThe symptomatic management of hemorrhagic shock complicated by open fractures is a great challenge, because it is also complicated by complex wound bleeding, bacterial infection, and bone defects. Inspired by the water absorption and cross‐sectional microstructure of sea cucumbers, in this study, a new sea cucumber‐like aerogel (GCG) is proposed. Its aligned porous structure and composition can stop bleeding rapidly and effectively with a blood clotting index of 3.73 ± 1.8%. More importantly, the data of in vivo hemostasis test in an amputating rat tail hemostatic model (15.69 ± 2.45 s, 26.95 ± 8.43 mg) and liver puncture bleeding model (23.77 ± 2.68 s, 36.22 ± 16.92 mg) also indicate the excellent hemostatic performance of GCG. In addition, GCG also shows a significant inhibitory effect on S. aureus and E. coli, which can prevent the occurrence of postoperative osteomyelitis. Not only that, after filling in the bone defect, it is shown that this GCG aerogel completely degrades eight weeks after surgery and induces new bone ingrowth, achieving functional regeneration after hemostasis of an open fracture defect. Generally, because of its combination of hemostatic, antibacterial, and osteogenic activities, this new aerogel is a promising option for open fractures treatment.

AbstractAdvances in vat photopolymerization (VP) 3D printing (3DP) technology enable the production of highly precise 3D objects. However, it is a major challenge to create dynamic functionalities and to manipulate the physical properties of the inherently insoluble and infusible cross‐linked material generated from VP‐3DP without reproduction. The fabrication of light‐ and high‐intensity focused ultrasound (HIFU)‐responsive cross‐linked polymeric materials linked with hexaarylbiimidazole (HABI) in polymer chains based on VP‐3DP is reported here. Although the photochemistry of HABI produces triphenylimidazolyl radicals (TPIRs) during the process of VP‐3DP, the orthogonality of the photochemistry of HABI and photopolymerization enables the introduction of reversible cross‐links derived from HABIs in the resulting 3D‐printed objects. While photostimulation cleaves a covalent bond between two imidazoles in HABI to generate TPIRs only near the surface of the 3D‐printed objects, HIFU triggers cleavage in the interior of materials. In addition, HIFU travels beyond an obstacle to induce a response of HABI‐embedded cross‐linked polymers, which cannot be attainable with photostimulation. The present system would be beneficial for tuning the physical properties and recycling of various polymeric materials, but it will also open the door for pinpoint modification, healing, and reshaping of materials when coupled to various dynamic covalent materials.

AbstractLayered metal halide perovskites have attracted enormous research attention over the last few years, befitting their unique optical and electronic properties. Low‐dimensional layered perovskites demonstrate great potential for various optoelectronic and sensing applications beyond photovoltaics. Herein, the recent progress and opportunities in 2D and quasi‐2D perovskites for light‐emitting diodes (LEDs), lasers, memristors, neuromorphic/synaptic applications, UV–vis photodetection, X‐ray detection, scintillators, and photocatalytic applications are reviewed. First, the crystal structure, characteristics, and fundamental properties of 2D layered perovskites are discussed. Recent efforts and developments of 2D and quasi‐2D metal halide perovskite for light‐emitting applications with excellent luminescence properties are reviewed. Unique properties of 2D perovskites, such as negligible leakage current due to restricted carrier transport, high stability, and hydrophobicity, make them viable for memristor devices. After discussing the memristor and neuromorphic devices using 2D perovskites, the outstanding performance of 2D perovskites in UV–vis photodetection including polarization‐sensitive photodetection is discussed. 2D perovskites recently proved as a superior candidate in X‐ray detection with high stability. Further, the scintillation properties of 2D perovskites for the detection of ionizing radiation are discussed. Finally, some of the very recent achievements and present future outlook, including exciting opportunities in this burgeoning field are highlighted.

AbstractThe application of immunotherapy in gastrointestinal (GI) cancers remains challenging because of the limited response rate and emerging therapeutic resistance. Combining clinical cohorts, multi‐omics study, and functional/molecular experiments, it is found that ANO1 amplification or high‐expression predicts poor outcomes and resistance to immunotherapy for GI cancer patients. Knocking‐down or inhibiting ANO1 suppresses the growth/metastasis/invasion of multiple GI cancer cell lines, cell‐derived xenograft, and patient‐derived xenograft models. ANO1 contributes to an immune‐suppressive tumor microenvironment and induces acquired resistance to anti‐PD‐1 immunotherapy, while ANO1 knockdown or inhibition enhances immunotherapeutic effectiveness and overcomes resistance to immunotherapy. Mechanistically, through inhibiting cancer ferroptosis in a PI3K‐Akt signaling‐dependent manner, ANO1 enhances tumor progression and facilitates cancer‐associated fibroblast recruitment by promoting TGF‐β release, thus crippling CD8+ T cell‐mediated anti‐tumor immunity and generating resistance to immunotherapy. This work highlights ANO1's role in mediating tumor immune microenvironment remodeling and immunotherapeutic resistance, and introduces ANO1 as a promising target for GI cancers’ precision treatment.

Published: June 2023

AbstractFloating‐Harbor syndrome (FLHS) is a neurodevelopmental disorder (NDD) caused by truncating variants in exons 33 and 34 of the SNF2‐related CREBBP activator protein gene (SRCAP). Truncating variants proximal to this location in SRCAP result in a non‐FLHS SRCAP‐associated NDD; an overlapping but distinct NDD characterized by developmental delay with or without intellectual disability (ID), hypotonia, normal stature, and behavioral and psychiatric issues. Here, we report a young woman who initially presented in childhood with significant delays in speech and mild ID. In young adulthood, she developed schizophrenia. On physical examination, she had facial features suggestive of 22q11 deletion syndrome. After non‐diagnostic chromosomal microarray and trio exome sequencing (ES), a re‐analysis of trio ES data identified a de novo missense variant in SRCAP that was proximal to the FLHS critical region. Subsequent DNA methylation studies showed the unique methylation signature associated with pathogenic sequence variants in non‐FLHS SRCAP‐related NDD. This clinical report describes an individual with non‐FLHS SRCAP‐related NDD caused by an SRCAP missense variant, and it also demonstrates the clinical utility of ES re‐analysis and DNA methylation analysis for undiagnosed patients, in particular, those with variants of uncertain significance.

AbstractConsidering the design of structures and materials for use as replacements for biological structures, polymer nanocomposites are desirable materials of construction since they have a large design space, allowing property customization. Biobased nanofibers are particularly suited for these applications since they have high specific mechanical properties and cytocompatibility. Motivated by these attributes, this work examines nanocomposite aerogels and an aerogel/hydrogel hybrid structure designed to mimic an intervertebral disc (IVD), with the aerogel and hydrogel serving as analogs for the annulus fibrosus and the nucleus pulposus, respectively. The aerogels and aerogel/hydrogel hybrid structure contain a mixture of biobased nanofibers, cellulose nanocrystals (CNCs) and chitin nanofibers (ChNFs), and a polyvinyl alcohol (PVA) matrix. Characterization of the structure and properties shows that the nanocomposite aerogels containing CNC/ChNF mixtures have larger pores and decreased mechanical properties as compared to aerogels containing only CNCs or only ChNFs. Building on these results, a hybrid comprised of a CNC/PVA aerogel and a CNC/ChNF/PVA hydrogel is constructed with mechanical properties similar to natural IVDs, providing initial validation of the hybrid concept for IVD replacements and pathways to customization through changing material composition in the aerogel and hydrogel and changing the aerogel and hydrogel fractions in the hybrid structure.

Published: June 2023

AbstractShandite with Ni3Pb2S2 chemical formula and Rm symmetry contains the kagome sublattice formed by transition metal atoms. Recent experimental results confirmed the possibility of successfully synthesizing Pd3Pb2Ch2 (Ch=S,Se) with the same structure. This paper theoretically investigates the dynamical properties of such compounds. Furthermore, we study the possibility of realizing Pt3Pb2Ch2 with the shandite structure. This study shows that the Pd3Pb2Ch2 and Pt3Pb2S2 are stable with Rm symmetry. In the case of Pt3Pb2S2, there is a soft mode, which is the source of the structural phase transition from Rm to Rc symmetry, related to the distortion within the kagome sublattice. This study discusses realized phonon nodal lines in bulk phonon dispersions in upper frequency modes. It shows that the shandite structure can host phonon surface states, with a strong dependence on the type of surface. Additionally, chiral phonons with circular motion of the Pb atoms around the equilibrium position are realized.

AbstractFor near‐infrared ground and space‐based astronomy, compact photonic devices can replace the large bulk optical components in spectrographs, frequency combs, beam combiners, and sky subtraction filters, thus saving cost, reducing volume, weight, and power requirements. Photonic integrated circuits (PICs), analogous to integrated circuits (IC) in electronics, are particularly powerful to address innovative miniaturized solutions. Here, we demonstrate two new instrument prototypes: the Potsdam Arrayed Waveguide Spectrograph (PAWS) built around an array waveguide grating (AWG) PIC and Hawaii2RG detector, and the Potsdam Comb (POCO), a frequency comb generated by nonlinear processes in a micro‐ring resonator photonic chip. PAWS is calibrated by the remotely located POCO via the fiber optic communication network of the Leibniz‐Institute for Astrophysics Potsdam (AIP). The vision of future astrophotonic solutions for instrumentation is pointing toward hybrid solutions of PIC and detector arrays that hold the promise to dramatically change the layout of telescope focal plane instrumentation.
An Incremental Capacity Analysis‐based State‐of‐health Estimation Model for Lithium‐ion Batteries in High‐power Applications

Published: June 2023

AbstractThe Incremental Capacity (IC) is a rich source of data for the state‐of‐health estimation of lithium‐ion batteries. This data is typically collected during a low C‐rate (dis)charge of the battery which is not representative of many real‐world applications outside the research laboratories. Here, this limitation is showcased to be mitigated by employing a new feature‐extraction technique applied to a large dataset including 105 batteries with cycle lives ranging from 158 to 1637 cycles. The state‐of‐health of these batteries is successfully predicted with a mean‐absolute‐percentage error below 0.7 % by using three regression models of support vector regressor, multi‐layer perceptron, and random forest. The methodologies proposed in this work facilitate the development of accurate IC‐based state‐of‐health predictors for lithium‐ion batteries in on‐board applications.

Published: June 2023

AbstractTo harness the synergistic effect of different polymer chains, poly(methyl(2‐(tris(2‐H methoxyethoxy)silyl)ethyl)siloxane)) grafted with Si‐tripodant centers (2550EO) known for their flexible structure was physically blended with poly(vinylidene fluoride‐co‐hexafluoropropylene (PVdF‐HFP). Here, 2550EO containing varying amounts of amide salts (LiF(SO2CF3)2 (LiTFSI)) was used as the main matrix. PVdF‐HFP was used in concentrations of up to 30 % to increase the film‐forming ability of 2550EO/LiTFSI, and a series of solid polymer electrolyte (SPE) membranes were prepared. After incorporating the blended SPE with a minute amount of organic carbonates (only 15 wt%), the electrochemical features, such as Li+ conductivity and transference number (tLi+), significantly increased. For example, a tLi+ of 0.42 and ionic conductivities of 0.64 and 0.3 S cm−1 at 60 °C and 25 °C, respectively, were achieved. In addition, the electrochemical stability exceeded 5 and 4.8 V at 25 °C and 60 °C, respectively. Thus, a high Li/LiFePO4 battery performance with high coulombic efficiencies exceeding 96 % and 98 % at 60 °C and 25 °C were achieved at 0.1 C, respectively. This was due to the superiority of the polysiloxane structure over its organic counterpart, attributed to its highly flexible backbone, high segmental mobility, and outstanding thermal and chemical stability.

Published: June 2023

AbstractWe investigate cointegration in prices of corn, soybean and sugarcane in Brazil using a fractional integration analysis, fractional cointegration in a pairwise set‐up and fractional cointegrating vector autoregressive (FCVAR) set‐up. Monthly real prices of sugarcane, corn and soybean are considered, in the period between March 2006 and May 2022. The results of fractional integration first show that the prices of these agricultural commodities are non‐mean reverting, and cointegrated in a pairwise fractional sense. The results, based on the FCVAR model, show the prices of the three commodities moving in different directions, that is, sugarcane and soybean negatively, while sugarcane and corn, and corn and soybean move in positive directions. The positive relationship between sugarcane and corn has implications for the ATR (‘açúcar total recuperável’ – total recoverable sugar, TRS) pricing of derivatives of two commodities, such as sugar and ethanol. Also, corn and soybean are close substitutes and are expected to have similar pricing dynamics over time. © 2023 Society of Industrial Chemistry and John Wiley & Sons Ltd.
Location of acupuncture points based on graph convolution and 3D deep learning in virtual humans
Authors: Ji Xiaoyun , Zhou Lanfeng 
Published: June 2023

AbstractAutomatic acupoint searching is an indispensable part of intelligent acupuncture robot. Clinical practice have proofed that Dazhu, Fengmen and Xinshu, which could be located by Dazhui, are curative when these points are acupuncture. The existing methods are mainly based on regular or image. The regular‐based methods are based on the experience of physicians, and the accuracy will decrease for different patients; While the image‐based methods will lose some features in image. In order to solve the existing problems, we propose a novel graph convolution mixed with point cloud deep learning method. In this method, the skinned multi‐person linear model is regarded as a graph structure input, and the coarsened graph is obtained by graph convolution. After feeding the coarsened graph into the PointNet network, the coordinates of Dazhui are output. Different from the existing methods, the proposed method can directly label the results on the adaptive model, thus improving the accuracy on different models. An optimization method based on graph structure is introduced for better fit the predicted acupoints to the surface. In addition, a dataset marked with Dazhui is constructed for training. Experiments show that the accuracy of positioning could meet the requirements of needle application under certain circumstances.

Published: June 2023

Key Clinical MessageNumerous techniques for provisionally replacing a single tooth at the aesthetic zone while planning for future dental implant placement, while soft and hard tissues heal, are critical in restorative treatment strategy. The available materials, simplicity, cost, and impact on the potential implant location should be considered when evaluating the treatment choices.AbstractReplacement of a single anterior tooth in the aesthetic zone while planning for future implant placement is crucial to the restorative treatment plan. Several methods exist for immediate provisionalisation of the extracted tooth while waiting for soft and hard tissue healing. Although there's a myriad of possible provisionalisation methods available, each option has its advantages and disadvantages. The treatment options should weigh various factors such as the available materials, ease of fabrication, costs, and the effect on the future implant site. This article describes three clinical cases demonstrating a simple yet cost‐effective technique to temporarily replace an extracted single anterior tooth, enhancing patient satisfaction and increasing compliance before receiving the definitive implant restoration. The pro and cons for each treatment option available as opposed to the technique involved in the three cases used are also described.

AbstractThe objective of this review is to interpret the usage of alternative renewable systems that is imperative for future developments on a global industrial scale. Microalgae have appeared as the most realistic source for biofuel generation due to the accumulation of lipids in most of the strains with rapid biomass expansion and greater photosynthetic efficiency than land plants. Microalgal‐derived feedstocks have a broad range of commercial advantages and can be used as promising renewable fuel substitutes with zero net CO2 emission. Important facets of algal‐based biofuel production, growing and harvesting techniques, approaches to thermochemical conversion, synthesis of commodities with added value, and recent breakthroughs in the field of synthetic biology for fuel production are covered.
Beyond Plastics-to-Plastics to Waste-to-Products: Opportunities for Closing the Carbon Cycle via Chemical Recycling
Authors: Lee Roh Pin , Keller Florian , Graebner Martin 
Published: June 2023

AbstractThe plastic crisis is a key driver for chemical recycling (CR), with focus placed on plastics circularity via Plastics‐to‐Plastics. This neglects its potential in enabling circularity for a wide range of carbon‐containing waste and hinders a critical discussion of its broader contributions to decarbonizing the chemical sector. To address this gap, four CR routes and their integration in the conventional waste treatment and chemical production value chains are briefly reviewed, and reasons proposed for a focus expansion to Waste‐to‐Products to realize opportunities for closing the carbon cycle via chemical recycling.
