Authors: Wang Qian , Pu Lei , Jia Caixia , Li Zhixin , Li Jun 
Published: November 2022

AbstractInfluence of temperature changes generated by plasma energy accumulation on bonding properties of carbon fiber composites (CFRP) was studied. The temperature field distribution on the bonding surface was built and tensile shear strength of the CFRP bonded components was evaluated. Results showed that the bonding strength was increased by 60.97% after the 5 min‐treatment. Because the energy accumulation could increase the local temperature of the bonding area to 195°C, a large amount of matrix resin was removed from the CFRP specimen. Then the surface wettability of the treated composite was greatly improved and the adhesive layer between the two bonded CFRP specimens became more similar to an interlayer in composites. The cohesive and interlaminar failure types occurred in the bonded component with the increased joint strength. Analysis of water contact angle, infrared spectroscopy, surface roughness and surface morphology indicated that the high‐surface free energy of the treated CFRP specimen and the mechanical interlocking between CFRP and adhesive caused by the decomposition of epoxy resin played a major role. When the treatment time further increased, the bonding area was severely damaged by the temperature of more than 215°C and then brittle fracture of the composites occurred, which was consistent with the subsequent decrease in bonding strength.

AbstractMulti‐phase functionally graded carbon nanotube‐reinforced composite damping structure (FG‐CNTRCDS) excels other composite structures in that it inherits the excellent performance of the functionally graded carbon nanotube‐reinforced composite, and exhibits an improved damping performance due to the added viscoelastic damping films. Despite its superior properties, investigations on dynamic properties of the FG‐CNTRCDS under clamped boundary conditions are still lacking. Aiming at filling this gap and paving the way to accurately design and analyze the FG‐CNTRCDS, a dynamic analytical model, which is based on the higher‐order shear deformation theory to formulate governing equations for predicting free vibration of FG‐CNTRCDS, has been established. The analytical solution that satisfies clamped boundary conditions is obtained using the Rayleigh–Ritz method. The existing analytical results from the literature have been used to verify the correctness of the theoretical model. In addition, effects of various structural parameters (such as volume fraction and core‐to‐skin thickness ratio) on dynamic performance have been investigated. Here, the dynamic performance refers to the first‐order natural frequency and the first‐order loss factor.

AbstractObjectiveNoninvasive Prenatal Diagnosis has recently been introduced for a limited number of monogenetic disorders. However, the majority of DNA diagnostics still require fetal material obtained using an invasive test. Recently, a novel technique, TRIC (Trophoblast Retrieval and Isolation from the Cervix), has been described, which collects fetal trophoblast cells by endocervical sampling. Since this technique has not been successfully replicated by other groups, we aimed to achieve this in the current study.MethodPregnant women referred for transvaginal chorionic villous sampling (CVS) were asked for an endocervical sample prior to CVS. The TRIC samples were processed to isolate trophoblast DNA. TRIC DNA was used in ForenSeq to determine the amount of maternal DNA contamination, and for Sanger sequencing in case of a monogenic disorder.Results23%–44% of samples had a sufficiently high fetal DNA fraction to allow genetic testing, as calculated by Sanger sequencing and ForenSeq, respectively.ConclusionWe have been able to successfully replicate the TRIC protocol, although with a much lower success rate as described by the original study performing TRIC. As we obtained the samples in the actual clinical setting envisioned, the method in its current setup is not advisable for use in prenatal diagnostics.

Published: November 2022

AbstractAdditively manufactured polymeric products for automotive, aerospace, and biomedical applications are usually intended for service in an outdoor environment with high mechanical loading conditions. The strength and sustainability of the products can be significantly degraded due to the outdoor environmental conditions such as UV light, moisture, heat, and so forth. In this research work, a novel weather‐resistant polymer (WRP) material, that is, acrylonitrile styrene acrylate (ASA), has been studied. Furthermore, this work aims to study the effect of process parameters and enhance the strength of WRP (ASA) specimens using the FFF process. The optimized process parameters, that is, build orientation (BO), extrusion temperature (ET), layer thickness (LT), and printing speed (PS), were identified based on the tensile and flexural strength using the Taguchi technique and statistical analysis. The best tensile and flexural strengths for the specimen were achieved at both orientations (XYZ and ZXY) TS: 255°C ET, 0.14 mm LT, 50 mm/s PS; and FS: 245°C ET, 0.28 mm LT, 50 mm/s PS, respectively. Regression model was developed to investigate the correlation between the process parameters with tensile and flexural strength. A validation test confirmed the findings, and the error between the actual and predicted values is less than ±10%.

AbstractObjectiveMany advanced cancer patients struggle with anxiety, depressive symptoms, and anger toward God and illness‐related stressors. Patients may perceive their illness as an injustice (i.e., appraise their illness as unfair, severe, and irreparable or blame others for their illness), which may be a risk factor for poor psychological and spiritual outcomes. This study examined relations between cancer‐related perceived injustice and psycho‐spiritual outcomes as well as potential mediators of these relationships.MethodsAdvanced lung (n = 102) and prostate (n = 99) cancer patients completed a one‐time survey. Using path analyses, we examined a parallel mediation model including the direct effects of perceived injustice on psycho‐spiritual outcomes (i.e., anxiety, depressive symptoms, anger about cancer, anger towards God) and the indirect effects of perceived injustice on psycho‐spiritual outcomes through two parallel mediators: meaning making and acceptance of cancer. We then explored whether these relations differed by cancer type.ResultsPath analyses indicated that perceived injustice was directly and indirectly—through acceptance of cancer but not meaning making—associated with psycho‐spiritual outcomes. Results did not differ between lung and prostate cancer patients.ConclusionsAdvanced cancer patients with greater perceived injustice are at higher risk for poor psycho‐spiritual outcomes. Acceptance of cancer, but not meaning making, explained relationships between cancer‐related perceived injustice and psycho‐spiritual outcomes. Findings support testing acceptance‐based interventions to address perceived injustice in advanced cancer patients.

Published: November 2022

AbstractIn the cold atmospheric plasma (CAP)‐assisted cancer treatment, the electroporation of cancer cell membranes occurs under the CAP itself electric field effect, leading to changes in membrane permeability. In this paper, using classical molecular dynamics simulations, the electroporation of pure or different cholesterol‐containing phospholipid bilayer models under different pulsed electric fields was studied. The results showed that the electroporation time under a nanosecond pulsed electric field was shorter, while a picosecond pulsed electric field had a stronger penetration effect. Increasing the electric field intensity or decreasing the frequency of cholesterol contents decreased the electroporation time. Our simulation complements the related studies on electroporation under a picosecond pulsed electric field and reveals the potential mechanism of CAP‐selective cancer cell apoptosis.

AbstractThe handling of plastic waste and the associated ubiquitous occurrence of microplastic poses one of the biggest challenges of our time. Recent investigations of plastic degrading enzymes have opened new prospects for biological microplastic decomposition as well as recycling applications. For polyethylene terephthalate, in particular, several natural and engineered enzymes are known to have such promising properties. From a previous study that identified new PETase candidates by homology search, we chose the candidate PET6 from the globally distributed, halophilic organism Vibrio gazogenes for further investigation. By mapping the occurrence of Vibrios containing PET6 homologs we demonstrated their ubiquitous prevalence in the pangenome of several Vibrio strains. The biochemical characterization of PET6 showed that PET6 has a comparatively lower activity than other enzymes but also revealed a superior turnover at very high salt concentrations. The crystal structure of PET6 provides structural insights into this adaptation to saline environments. By grafting only a few beneficial mutations from other PET degrading enzymes onto PET6, we increased the activity up to three‐fold, demonstrating the evolutionary potential of the enzyme. MD simulations of the variant helped rationalize the mutational effects of those mutants and elucidate the interaction of the enzyme with a PET substrate. With tremendous amounts of plastic waste in the Ocean and the prevalence of Vibrio gazogenes in marine biofilms and estuarine marshes, our findings suggest that Vibrio and the PET6 enzyme are worthy subjects to study the PET degradation in marine environments.

Published: November 2022

AbstractThis article investigates the problem of adaptive event‐triggered resilient stabilization for nonlinear semi‐Markov jump systems with DoS attacks. In this article, both DoS attacks and event‐triggered transmission strategy (ETTS) are considered. The DoS attacks may disturb the event‐triggered strategy, which implies that the original inequality condition of ETTS will no longer be satisfied. Different from the traditional ETTS, the adaptive ETTS is designed to reduce bandwidth usage. Based on the adaptive ETTS and resilient controller, the sufficient condition for stochastic stability of the closed‐loop system is proposed. Then, the calculation method of controller and observer parameters is given in the form of linear matrix inequality. Finally, the proposed adaptive event‐triggered resilient controller is applied to a single‐link robot arm model, which can show effectiveness of the proposed method.

The discovery of extremely effective heteroatom dopant catalysts for electrochemical reduction reactions is crucial for ambient nitrogen fixation. In this paper, we investigated nitrogen and boron doped biomass carbon as an effective electrocatalyst for nitrogen reduction reaction (NRR), where the N, B content ratio, and pyrolysis temperature were optimized to improve N2 adsorption and N≡N cleavage. The resulting 600ACNB‐213 exhibits outstanding improvement in fixing N2 to ammonia with a high ammonia production rate (41 μg h−1 mg−1 at −1 V vs. RHE), outperforming other metals and carbon‐based materials and even being superior to noble‐metal‐based catalysts. Besides, there indicates good stability through six cycles of testing. Experiments and analyses demonstrated that pyridinic‐N and BC2O were active sites for ammonia synthesis and that their contents' ratio was critical for enhancing ammonia production on N, B doped carbon. These sites can enhance step‐by‐step catalytic reactions through rapid electron transfer processes by strengthening the conductivity of carbon‐based materials with dopants, substantially improving the overall catalytic performance. This research suggests that designing carbon co‐doped with N, B for effective N2 reduction electrocatalysts has a significant potential.

AbstractWater oxidation is one of the most challenging steps in CO2 photoreduction, but its influence on CO2 photoreduction is still poorly understood. Herein, the concept of accelerating the water oxidation kinetics to promote the CO2 photoreduction is realized by incorporating supramolecular porphyrin nanosheets (NS) into the C3N4 catalyst. As a prototype, porphyrin‐C3N4 based van der Waals heterojunctions with efficient charge separation are elaborately designed, in which the porphyrin and C3N4 NS serve as the water oxidation booster and CO2 reduction center, respectively. Theoretical calculations and relevant experiments demonstrate that the added porphyrin NS reverses the rate‐limiting step in the water oxidation while reducing its energy barrier, thus resulting in faster reaction kinetics. Therefore, the optimal sample shows excellent performance in visible‐light‐driven CO2 reduction with a maximum CO evolution rate of 16.8 µmol g−1 h−1, which is 6.8 times that of the C3N4 NS and reaches the current state of the art for C3N4‐based materials in CO2 photoreduction. Overall, this work throws light that accelerating water oxidation kinetics can effectively improve the CO2 photoreduction efficiency.

AbstractDeveloping high‐efficiency and cost‐effective bifunctional catalysts for water electrolysis is fascinating but still remains challenging. Thus, diverse strategies have been utilized to boost the activity toward oxygen/hydrogen evolution reactions (OER/HER) for water splitting. Among them, composition and structure engineering as an effective strategy has received extensive attention. Here, by means of a self‐sacrificing template strategy and simultaneous regulation of the composition and structure, Fe‐incorporated Ni/MoO2 heterostructural (NiFe/Fe‐MoO2) hollow nanorod arrays are designed and constructed. Benefiting from abundant catalytic active sites, high intrinsic activity, and fast reaction kinetics, NiFe/Fe‐MoO2 exhibits superior OER (η20 = 213 and 219 mV) and Pt‐like HER activity (η10 = 34 and 38 mV), respectively, in 1 m KOH and alkaline seawater media. This results in attractive prospects in alkaline water and seawater electrolysis with only voltages of 1.48 and 1.51 V, and 1.69 and 1.73 V to achieve current densities of 10 and 100 mA cm−2, respectively, superior to the Pt/C and RuO2 pair as a benchmark. Undoubtedly, this work provides a beneficial approach to the design and construction of noble‐metal‐free bifunctional catalysts toward efficient hydrogen production from alkaline water and seawater electrolysis.

AbstractThe paper presents integrated effects of concrete samples size and fibers amount on compressive strength of high‐ and ultra‐high strength concretes based on reactive powders. Ready to use the self ‐ compacting mix of high‐performance concrete, was applied. The main aim of the work was to determine compressive strength correlation coefficients for size of cubic samples and integrated compressive strength correlation coefficients for the size of cubic samples including fibers ratio. The article presents the results of experimental tests of compressive strength for 3 sizes of cubic samples, i.e. 40, 100, and 150 mm, with the application of the steel fibers ratio of 0%, 2%, 4% for each sample size. Concrete air content and cone flow test studies were performed for all research series. The obtained results show a diversified influence of the size of the samples and the amount of steel fibers on the results of concrete compressive strength of high‐ and ultra‐high strength concretes based on reactive powders. Namely, the compressive strength correlation coefficient for the size of cubic samples was determined in the range 1.0–1.3, while the integrated compressive strength correlation coefficient the for size of cubic samples including fibers ratio is in the range 1.0–1.47.

AbstractSodium metal has been regarded as the potential alternative for metal batteries owing to its advantages of high theoretical capacity and abundant reserves. Nevertheless, propagation of Na dendrites can boost the interfacial instability of Na metal, retarding its practical implementation. Thus, the Na–Ga alloy layer is designed and fabricated by in situ rolling of metal Ga on the surface of Na metal. This alloy layer possesses good sodiophilicity, which can effectively protect Na metal and favor the uniform Na+ deposition, obtaining the inhibition of Na dendrites growth. Consequently, the symmetric cells assembled by the alloy‐layer protected Na metal electrodes (NGAL‐Na||NGAL‐Na) have a long lifetime (468 h) even under a high plating/stripping capacity of 6 mAh cm−2 in carbonate electrolyte. The full battery of NGAL‐Na||Na3V2(PO4)3 is able to sustain an excellent rate capability of 100 mAh g−1 after 500 cycles at 10 C under ambient temperature. This work provides a new route to prevent metal anodes from severe dendrite growth, and paves the way toward safer and stable‐performing metal‐based rechargeable batteries.

AbstractA 3‐week‐old pedigree British blue bull, weighing 70 kg, presented with soft tissue swelling of the distal left forelimb, with a discharging sinus associated with a granulating wound (pressure sore). Involvement of the metacarpophalangeal joint was suspected. There were also granulating wounds on the dorsal aspect of both metacarpophalangeal joints and laterally on both tarsi. Radiography, arthrocentesis, arthroscopy and joint lavage were carried out under general anaesthesia and the external wounds were debrided and dressed. Intra‐articular antibiotics were given at the time of surgery and systemic antibiotics and anti‐inflammatories were given for 14 days afterwards. The calf made a good recovery and returned to normal function.
Long‐time behavior of shape design solutions for the Navier–Stokes equations
Authors: Simon John Sebastian H. 
Published: November 2022

AbstractWe investigate the behavior of dynamic shape design problems for fluid flow at large time horizon. In particular, we shall compare the shape solutions of a dynamic shape optimization problem with that of a stationary problem and show that the solution of the former approaches a neighborhood of that of the latter. The convergence of domains is based on the ‐topology of their corresponding characteristic functions, which is closed under the set of domains satisfying the cone property. As a consequence, we show that the asymptotic convergence of shape solutions for parabolic/elliptic problems is a particular case of our analysis. Last, a numerical example is provided to show the occurrence of the convergence of shape design solutions of time‐dependent problems with different values of the terminal time T to a shape design solution of the stationary problem.
An analytical approach to study kinematics of shock waves in a dusty, cylindrical gas flow

Published: November 2022

AbstractIn this article, the developmental behaviour of one‐dimensional shock waves in a dusty, rotational flow has been considered. The mathematical scheme based on the kinematics of one‐dimensional fluid flow for the derivation of an infinite hierarchy of transport equations has been employed. The scheme is a truncation procedure which helps to examine the system of transport equations in a simple form. The first two approximations are studied to illustrate the effects of dust and rotational parameters.

Published: November 2022

Abstract
Since 1969 Lunar Laser Ranging (LLR) data have been collected by different observatories and analysed by various analysis groups. LLR is providing the longest time series of any space geodetic technique for studying the Earth-Moon dynamics. In recent years, observations have been carried out with larger telescopes and at infra-red (IR) wavelength, resulting in a better distribution of precise LLR data over the lunar orbit and the observed retro-reflectors on the Moon. The increased number of high-accuracy observations allows for more accurate determination of Earth Orientation Parameters (EOPs) from LLR data compared to previous years. In this study we focus on ΔUT1 results from different constellations and compare our LLR solution to the IERS EOP C04 series.
