Published: January 2023

AbstractBackgroundThe use of external fixators to treat foot and ankle deformities remains a challenge in orthopedic surgery due to their diversity. We hope to improve the automation and accuracy of the correction process.MethodsA three‐degree‐of‐freedom (3‐DOF) electromotor‐driven external fixator for uniplanar foot and ankle deformities was proposed. Computer‐assisted correction software was developed to help surgeons use digital technology to measure the required parameters from patients' X‐ray radiographs. The correction trajectory and the prescriptions were generated in the software based on the proposed correction strategy.ResultsTwo clinical cases were simulated to verify the correction ability of the developed external fixator. The results showed that the angular and displacement deformities were well corrected.ConclusionsThe developed external fixator can accurately and automatically correct foot and ankle deformities with the help of computer‐assisted correction software, which significantly reduces the burden on surgeons and patients.
Factors influencing purchase intention for recycled products: A comparative analysis of Germany and South Africa
Authors: Dobbelstein Thomas , Lochner Carina 
Published: January 2023

AbstractDue to an increasing demand, companies have started producing recycled products. However, little is known about the specific purchase behavior. Hence, this study analyses the factors influencing purchase intention for recycled products including differences related to different types of products and between Germany and South Africa. A quantitative study in Germany (n = 603) and South Africa (n = 692). shows that purchase intention is significantly higher in South Africa. The influencing factors (individual, product, and context related constructs) are the same in both countries, but they differ regarding their strength. Thus, the factor “attitude/environmental concern” has the strongest influence in South Africa, while it is “value/accessibility” in Germany. Furthermore, purchase intention for mobile phones is generally smaller than for t‐shirts and toilet paper. Purchase intention for recycled t‐shirts is significantly higher in South Africa than in Germany.

Published: January 2023

AbstractConstructing peculiar carbon‐based networks built from hybrid structures has been considered as an effective approach to establish a superior scaffold for immobilization of nanoparticles. Herein, we demonstrate a facile and green approach to prepare cobalt oxides (CoOx)‐based anode, which is realized by rationally exploiting unique properties of carbonized bacterial cellulose (CBC) and graphene (GN). The unique configuration of GN/CoOx/CBC composite fully enables utilization of the synergistic effects from both three‐dimensional nanofibrous network and two‐dimensional “flexible confinement” function. Benefiting from their intriguing structural features, the synthesized composite is directly used as electrode for lithium‐ion batteries (LIBs), and achieves superior flexibility and reliability, enhanced energy/power density and outstanding cycling stability.

AbstractN, P dual‐doped watermelon peel‐derived carbon (NPW) was prepared and found to exhibit a larger specific surface area of 1809 m2 g−1 and improved hierarchically interconnected pores than N‐doped and P‐doped carbons. The NPW electrode exhibits excellent electrochemical activity in a three‐electrode setup with 1 M H2SO4, 6 M KOH, and 1 M Na2SO4 electrolytes; with high specific capacitance (498.8, 397.6, and 378.6 F g−1 at 1 A g−1, respectively) and an average capacitance retention of ∼96.9 % after 10,000 charge‐discharge cycles at 10 A g−1. The NPW//NPW‐based symmetric cell with 1 M H2SO4‐PVA‐electrolyte provided a high energy density of 71.84 Wh kg−1 at 1 A g−1 and a specific capacitance of 263.9 F g−1. In the neutral electrolyte, NPW showed a wider operating voltage window of up to 2.0 V with no discernible anodic current and delivered 97.11 Wh kg−1 energy density.

AbstractTackling the current problem of antimicrobial resistance (AMR) requires fast, inexpensive, and effective methods for controlling and detecting antibiotics in diverse samples at the point of interest. Cost‐effective, disposable, point‐of‐care electrochemical biosensors are a particularly attractive option. However, there is a need for conductive and versatile carbon‐based materials and inks that enable effective bioconjugation under mild conditions for the development of robust, sensitive, and selective devices. This work describes a simple and fast methodology to construct an aptasensor based on a novel graphene derivative equipped with alkyne groups prepared via fluorographene chemistry. Using click chemistry, an aptamer is immobilized and used as a successful platform for the selective determination of ampicillin in real samples in the presence of interfering molecules. The electrochemical aptasensor displayed a detection limit of 1.36 nM, high selectivity among other antibiotics, the storage stability of 4 weeks, and is effective in real samples. Additionally, structural and docking simulations of the aptamer shed light on the ampicillin binding mechanism. The versatility of this platform opens up wide possibilities for constructing a new class of aptasensor based on disposable screen‐printed carbon electrodes usable in point‐of‐care devices.
Molecular Imprinted BiVO4 Microswimmers for Selective Target Recognition and Removal

Published: January 2023

AbstractAnalogous to photosynthetic systems, photoactive semiconductor‐based micro/nanoswimmers display biomimetic features that enable unique light harvesting and energy conversion functions and interactions with their surroundings. However, these artificial swimmers are usually non‐selective and provide ineffective target recognition, resulting in poor surface analyte binding that affects the overall reactivity and motion efficiency. Here, the surface engineering of light‐driven BiVO4 microswimmers by molecular imprinting polymerization is presented. After embedding surface recognition sites, the modified microswimmers can self‐propel in a solution of a target molecule, without requiring toxic fuels, and degrade the target selectively in a pollutant mixture. These findings show that optimizing the design of semiconductor‐based microswimmers with specific target recognition cavities on their surface is a promising strategy to achieve selective capture and degradation of organic pollutants, which is otherwise impossible because of the non‐selective behavior of photogenerated reactive radicals. Moreover, this study provides a unique strategy to enhance the motion capabilities of single‐component photocatalytic microswimmers in a specific chemical environment.

Published: January 2023

AbstractImmunotherapy is considered to be one of the most promising methods to overcome cancer. Immunogenic cell death (ICD), as a special form of cell death that can trigger an antitumor immune response, has attracted increasing attention for cancer immunotherapy. Presently, ICD‐mediating immunotherapy needs to overcome many hurdles including a lack of targeted delivery systems for ICD inducers, insufficient antitumor immunity, and the immunosuppressive tumor microenvironment. Recent research has demonstrated that nano‐biomaterials exhibit unique biochemphysical properties at the nanoscale, providing a prospective approach to overcoming these obstacles. In this review, the authors first survey the occurrence, processes, and detection methods of ICD. Subsequently, the recent advances of nano‐biomaterials applied to enhance ICD according to the key steps in the process of ICD, particularly with a focus on the mechanisms and lifting schemes are investigated. Finally, based on the achievement in the representative studies, the prospects and challenges of nanotechnology in ICD for cancer therapy are discussed to enable clinical translation.

AbstractCrack control throughout the service life of a structure has always been a challenging task for engineers and asset owners, particularly those who are involved with the design and construction of structures with increased durability requirements, such as liquid retaining structures, nuclear containment buildings or structures in direct contact with ground, but also other externally restrained structures. For these reasons, several standardized methods exist throughout the global engineering community which encompass differences between them. This work is a state‐of‐the‐art review of the methods for crack width control due to imposed strains recommended by different regulatory documents from Europe, USA, Australia and Japan, and provide a reasonable degree of guidance with respect to the assumptions, possibilities and restrictions of each method. This work resonates with the scope of the RILEM TC 287‐CCS: Early age and long‐term crack width analysis in RC structures.
Ionic Liquids Containing Silsesquioxane and Cyclic Siloxane Frameworks
Authors: Kaneko Yoshiro 
Published: January 2023

AbstractThis paper describes the author's recent work on the preparation and properties of thermally stable ionic liquids (ILs) containing siloxane frameworks. Quaternary ammonium and imidazolium salt‐type ILs containing random oligosilsesquioxane frameworks were successfully prepared via the hydrolytic condensation of the corresponding organotrialkoxysilanes by using an aqueous superacid bis(trifluoromethanesulfonyl)imide (HNTf2) solution as a catalyst and solvent. Imidazolium salt‐type ILs containing polyhedral oligomeric silsesquioxane (POSS) frameworks were also prepared through a reaction similar to that described above by using a water/methanol mixed solution of HNTf2. In addition, amorphous POSSs with two types of ionic groups randomly distributed in the side chain were prepared. These POSSs were ILs exhibiting fluidity at relatively low temperatures. Furthermore, imidazolium and ammonium salt‐type ILs containing cyclic oligosiloxane frameworks were prepared through a reaction similar to that of the corresponding organodialkoxysilanes. The thermal decomposition temperatures of the above ILs containing siloxane frameworks were higher than those of general ILs.

Published: January 2023

AbstractHydrogel beads are emerging as alternate adsorbent material for the batch or continuous column treatment of dye wastewater. Polysaccharide‐based gel beads are preferred for their uniform shape and size, large specific surface area, and easy separation by filtration and subsequent reuse. In this work, we prepare and rheologically characterize UV‐active κ‐carrageenan/TiO2 beads for the adsorption and degradation of dyes. The 3–4 mm sized nanocomposite beads are formed by the extrusion of κ‐carrageenan/TiO2 gel solution in salt solutions. The maximum increase in modulus was observed with the addition of 1% w/v TiO2 to κ‐carrageenan and subsequent crosslinking with mixed salt of KCl and CaCl2. κ‐carrageenan/TiO2 beads crosslinked by mixed salt of KCl and CaCl2 have higher adsorption capacity, as compared to beads crosslinked with single salt of KCl. The kinetic study indicated the chemisorption of Methylene Blue on the bead surface. κ‐carrageenan/TiO2 beads showed higher degradation for Methylene Blue and Nile Blue A than Rhodamine B in 5 and 50 ppm each multicomponent dye systems under UV irradiation. The κ‐carrageenan/TiO2 beads could form a porous column for the selective adsorption of positively charged dyes from a multicomponent dye system.

AbstractMagnetic methods of exploration have proved to be efficient and have potential in the gold mineralization industry. New magnetic processing technologies aid in improving the process of interpretation and gold opportunity identification. In this work, we show the possible application of combined digital magnetic filters to explore new gold mineralization localities with application to a well-known Au mineralization zone. Um Garayat (UG) region, southeastern desert, Egypt, is an ancient example of a potential area for gold mining. Modern analysis showed that other types of mineral concentrations are present. So, exploiting the magnetic signature of the area for future investment is of great interest. The old UG gold mine is characterized by volcanic and tectonic features such as faulting and folding that affect the arc sedimentary rock sequence of repeated deformation stages. A thorough geophysical effort has been carried out around the old gold mine in the UG area to explore the extension of mineralized ore deposits. A detailed geophysical survey using magnetics was carried out in this study together with the available aeromagnetic data. Field data sets on appropriate sites were measured, processed, and evaluated by suitable software. High magnetic anomalies were detected based on grid filter analysis and contact occurrence maps as marked as possible ore deposits after satisfying the geologic conditions for gold formation. An integrated understanding of attained results revealed that the new possible ore deposits are related directly to fault and fracture zones in the shape of lenses of variable thickness in this zone. Results show that newly detected mineral occurrences in the UG area are also controlled by major faults and hydrothermal solution enrichment along fault zones at a depth ranging from 20 to 70 m. Favorable fault/joint mineralized places were located. The relationship between the Au-quartz vein's strike direction compared with magnetic anomaly lineament analysis was studied. Search for new sources of Au and other mineral deposits in addition to quartz veins is needed as pockets of accumulated mineral-rich rock fragments are deposited in drainage wadis and fault/joint zones because of hydrothermal solution enrichment.
Metric Compactness Criteria Involving Sequences of Mappings and a Proof of the Ascoli–Arzelà Theorem with the use of Bernstein Polynomials
Authors: Jachymski Jacek 
Published: January 2023

AbstractWe establish inter alia a compactness criterion in metric spaces involving a sequence of completely continuous mappings, which is continuously convergent, in the sense of H. Hahn, to the identity mapping. For Banach spaces, the linear version of that result coincides with the compactness theorem due to Mazur. We also present a new proof of the Ascoli–Arzelà theorem, in which we use the above compactness criterion applied to the sequence of Bernstein operators.
Towards circular economy by valorization of waste upholstery textile fibers in fibrous wood-based composites production
Authors: Suchorab Barbara , Wronka Anita , Kowaluk Grzegorz 
Published: January 2023

AbstractThe aim of the research was to utilize textile waste by adding upholstery fabric fibers with different content (0, 5, 10, and 20% by weight referred to dry wood fibers) to high density fiberboards (HDF) and analyze selected physical and mechanical properties of the obtained boards. Tests of mechanical (modulus of elasticity in bending and bending strength, surface soundness, internal bond, screw withdrawal resistance) and physical (density profile, swelling in thickness after immersion in water, water absorption) properties were performed. The results show that the increasing content of textile fibers in HDF panels has the strongest negative influence on mechanical properties, especially internal bond, and screw withdrawal resistance. Modulus of elasticity and modulus of rupture also decreased, but still fulfilled the requirements of European standards. No significant influence of rising content of textile fibers on HDF thickness swelling and water absorption has been found. It can be concluded that, depending on further application of HDF, it is possible to utilize the recovered upholstery textile fibers as a reasonable addition to wood fibers when producing HDF panels. It is also a step toward carbon storage extension, which is fixed in textile fibers.
The radiologist’s role in a multidisciplinary approach to cancer in pregnancy

Published: January 2023

AbstractPregnancy-associated cancer (PAC) occurs in approximately 1 in 1000 pregnancies, and the incidence is expected to rise due to delayed childbearing (Silverstein et al. in JCO Oncol Pract 16:545–557, 2020; Woitek et al. in ESMO Open 1:e000017, 2016). Diagnosis and management of PACs are challenging and diagnosis is often delayed as symptoms may overlap with physiologic changes of pregnancy (Jha et al. in RadioGraphics 42:220005, 2022). These patients are best cared for by a multidisciplinary healthcare team composed of experts (Silverstein et al. in JCO Oncol Pract 16:545–557, 2020). Management of these patients must balance optimal maternal care with potentially harmful fetal effects. This involves honest, forthright, and sometimes difficult discussions between the care team and the patient throughout the entirety of care. Radiologists play a significant role in timely cancer diagnosis, staging and follow-up during and after pregnancy, accurate determination of gestational age, and in assessing fetal growth and well-being throughout pregnancy.

Authors: Salimi Yazdan , Shiri Isaac , Akavanallaf Azadeh , Mansouri Zahra , Arabi Hossein , Zaidi Habib 
Published: January 2023

Abstract
Objectives
This study aimed to improve patient positioning accuracy by relying on a CT localizer and a deep neural network to optimize image quality and radiation dose.

Methods
We included 5754 chest CT axial and anterior–posterior (AP) images from two different centers, C1 and C2. After pre-processing, images were split into training (80%) and test (20%) datasets. A deep neural network was trained to generate 3D axial images from the AP localizer. The geometric centerlines of patient bodies were indicated by creating a bounding box on the predicted images. The distance between the body centerline, estimated by the deep learning model and ground truth (BCAP), was compared with patient mis-centering during manual positioning (BCMP). We evaluated the performance of our model in terms of distance between the lung centerline estimated by the deep learning model and the ground truth (LCAP).

Results
The error in terms of BCAP was − 0.75 ± 7.73 mm and 2.06 ± 10.61 mm for C1 and C2, respectively. This error was significantly lower than BCMP, which achieved an error of 9.35 ± 14.94 and 13.98 ± 14.5 mm for C1 and C2, respectively. The absolute BCAP was 5.7 ± 5.26 and 8.26 ± 6.96 mm for C1 and C2, respectively. The LCAP metric was 1.56 ± 10.8 and −0.27 ± 16.29 mm for C1 and C2, respectively. The error in terms of BCAP and LCAP was higher for larger patients (p value < 0.01).

Conclusion
The accuracy of the proposed method was comparable to available alternative methods, carrying the advantage of being free from errors related to objects blocking the camera visibility.

Key Points
• Patient mis-centering in the anterior–posterior direction (AP) is a common problem in clinical practice which can degrade image quality and increase patient radiation dose.
• We proposed a deep neural network for automatic patient positioning using only the CT image localizer, achieving a performance comparable to alternative techniques, such as the external 3D visual camera.
• The advantage of the proposed method is that it is free from errors related to objects blocking the camera visibility and that it could be implemented on imaging consoles as a patient positioning support tool.

AbstractThis paper discusses various frequency modulation and intensity modulation capabilities within a sample of direct laser current modulated identical vertical cavity surface emitting laser diodes. The presented analysis is based on measurements of the spectral amplitudes as a function of the applied modulation power at a constant modulation frequency of 3.517 GHz. Their evaluation by Bessel function fits produces the three modulation parameters: frequency modulation index, intensity modulation index (via the $$\alpha$$
α
parameter) and the side band asymmetry of the first order side bands. The variation of the laser diode’s modulation capability is discussed. It is found that the individual laser diodes show a significant variations in their modulation capabilities. Thus an experimental preselection of the laser diode is required to find laser diodes which are suitable as a light source for atomic vapour applications, with special emphasis on a coherent population trapping-based scalar magnetometers.
