Published: January 2024

AbstractHighly anticipated potassium metal batteries possess abundant potassium reserves and high theoretical capacity but currently suffer from poor cycling stability as a result of dendritic growth and volume expansion. Here, carbon cloths modified with different functional groups treated with ethylene glycol, ethanolamine, and ethylenediamine are designed as 3D hosts, exhibiting different wettability to molten potassium. Among them, the hydroxyl‐decorated carbon cloth with a high affinity for potassium can achieve molten potassium perfusion (K@EG‐CC) within 3 s. By efficiently inducing the uniform deposition of metal potassium, buffing its volume expansion, and lowering local current density, the developed K@EG‐CC anode alleviates the dendrite growth issue. The K@EG‐CC||K@EG‐CC symmetric battery can be cycled stably for 2100 h and has only a small voltage hysteresis of ≈93 mV at 0.5 mA cm−2. Moreover, the high‐voltage plateau, high energy density, and long cycle life of K metal full batteries can be realized with a low‐cost KFeSO4F@carbon nanotube cathode. This study provides a simple strategy to promote the commercial applications of potassium metal batteries.

AbstractThe existence of many background blood cells hinders the accurate identification of circulating tumor cells (CTCs) in the blood of cancer patients. To unlock this limitation, a hydrodynamic sorting‐mechanotyping cytometry (HSMC) integrated with a sorting‐concentration chip and a detection chip is proposed for simultaneously achieving the high‐throughput cell sorting and the multi‐parameter mechanotyping of the sorted tumor cells. The HSMC adopts the spiral inertial microfluidics for label‐free sorting of cells in a high‐throughput manner, allowing the efficient enrichment of tumor cells from the large background blood cells. Then, the sorted cells are concentrated by the concentration unit and finally passed through the detection unit for hydrodynamic deformation. The HSMC has a high throughput for sorting and detection and can successfully reveal the differences in the cellular mechanical properties. After characterizing and optimizing the single chips, the identification of white blood cells (WBCs) and three types of tumor cells (A549, MCF‐7, and MDA‐MB‐231 cells) is successfully achieved. The identification accuracies for WBCs and different tumor cells are all larger than 94%, while the highest identification accuracy is up to 99.2%. This study envisions that the HSMC will offer an avenue for the analysis of single cell intrinsic mechanics in clinical medicine.

Published: January 2024

AbstractA simple quality by design aided stability indicating method was developed for quantification of sonidegib (SONI) and its process related impurities using on ultra‐performance liquid chromatography in bulk drug substance. AutoChrom and Design‐Expert software were used to predict physicochemical properties, draw Ionization graphs, and generate analytical target profile. SONI was subjected to forced degradation conditions, such as oxidative, acid hydrolysis, base hydrolysis, hydrolytic, thermal, and photolytic hydrolysis. All degradation products and process contaminants were separated using an Acquity Ethylene Bridged Hybrid C18 column in gradient elution mode with a mobile phase containing 0.02 M ammonium acetate buffer and acetonitrile: methanol (80:20 v/v). The predicted physicochemical properties are accurate and they facilitated for selection of robust conditions in development of chromatographic method with minimal trials. The developed method can be used for quantification of drug and its process related impurities in bulk drugs.

Published: January 2024

AbstractBiaxially prestressed large concrete structures of the confinement building in nuclear power plants (NPPs) should meet the safety requirement for the extension of the service time. Long‐term delayed strains of concrete are one of the key factors determining the safety factor in these structures. This article presents 30‐year long in situ measurement results of strain evolution of confinement buildings in four different NPPs. The delayed strains are predicted at a material level using the next‐generation Eurocode‐2, and the influence of temperature as proposed by thefibmodel code 2010, making use of delayed strain characteristics of the corresponding concrete from a previous study. We found that the default law given in Eurocode underestimates the delayed strain. However, with the possibility of adjusting the shrinkage and creep laws, the prediction results fit with a good accuracy for the in situ measurement.

ABSTRACTObjectivesTo describe the types of brain injury and subsequent neurodevelopmental outcome in fetuses and neonates from pregnancies with twin–twin transfusion syndrome (TTTS). Additionally, to determine risk factors for brain injury and to review the use of neuroimaging modalities in these cases.MethodsThis was a retrospective cohort study of consecutive TTTS pregnancies treated with laser surgery in a single fetal therapy center between January 2010 and January 2020. The primary outcome was the incidence of brain injury, classified into predefined groups. Secondary outcomes included adverse outcome (perinatal mortality or neurodevelopmental impairment), risk factors for brain injury and the number of magnetic resonance imaging (MRI) scans.ResultsCranial ultrasound was performed in all 466 TTTS pregnancies and in 685/749 (91%) liveborn neonates. MRI was performed in 3% of pregnancies and 4% of neonates. Brain injury was diagnosed in 16/935 (2%) fetuses and 37/685 (5%) neonates and all predefined injury groups were represented. Four fetal and four neonatal cases of cerebellar hemorrhage were detected. Among those with brain injury, perinatal mortality occurred in 11/16 (69%) fetuses and 8/37 (22%) neonates. Follow‐up was available for 29/34 (85%) long‐term survivors with brain injury and the mean age at follow‐up was 46 months. Neurodevelopmental impairment was present in 9/29 (31%) survivors with brain injury. Adverse outcome occurred in 28/53 (53%) TTTS individuals with brain injury. The risk of brain injury was increased after recurrent TTTS/post‐laser twin anemia–polycythemia sequence (TAPS) (odds ratio (OR), 3.095 (95% CI, 1.581–6.059); P = 0.001) and lower gestational age at birth (OR per 1‐week decrease in gestational age, 1.381 (95% CI, 1.238–1.541); P < 0.001).ConclusionsBased on dedicated neurosonography and limited use of MRI, brain injury was diagnosed in 2% of fetuses and 5% of neonates with TTTS. Adverse outcome was seen in over half of cases with brain injury. Brain injury was related to recurrent TTTS/post‐laser TAPS and a lower gestational age at birth. © 2024 The Authors.

Published: January 2024

AbstractA 2‐year‐10‐month‐old, male, neutered French bulldog presented with a rectal prolapse, rectal bleeding, weight loss and anaemia with left hindlimb oedema. Biopsies of the recto‐anal junction identified moderate neutrophilic and lymphoplasmacytic erosive proctitis, with moderate vascular hyperaemia and moderately ectatic vessels in the rectal submucosa. Abdominal computed tomography identified intra‐abdominal arteriovenous malformations involving the mesenteric arteries, colic arteries, the vertebral venous plexus and femoral veins causing concurrent left hindlimb oedema. The malformations were too extensive to allow for surgical resection of the affected area of intestine. The patient's clinical signs initially responded to immunosuppressive therapy with corticosteroids. However, the patient's clinical signs progressed, and the dog was euthanased 4 months after initial presentation. To the authors’ knowledge, this is the first report of such extensive arteriovenous anomalies also involving rectal prolapse and suspected colonic ectasia in a dog.
Singular integral method based closed form solution for moving EMPS model in semipermeable two‐equal‐collinear cracked MEE material
Authors: Kumar Ashish , Sharma Kuldeep , Bui Tinh Quoc 
Published: January 2024

AbstractThis paper presents the analytical closed‐form solutions of moving two equal collinear semipermeable cracks in magneto‐electro‐elastic material considering the strip electric‐magnetic polarization saturation (EMPS) model. To simulate the dynamic/moving cracks problem, two equal collinear Yoffe type cracks moving with a constant subsonic velocity along the plane of the cracks is considered. The problem is solved by considering semipermeable crack face conditions and under the in‐plane electro‐magnetic‐mechanical loading. Applying distributed dislocation technique and symmetry of the collinear cracks, the problem is reduced into simultaneous singular integral equations which have been solved in closed form expressions using finite Hilbert approach. The explicit expressions for dynamic distributed dislocation densities, crack opening displacement (COD), crack opening potential (COP), crack opening induction (COI), and local stress intensity factors (LSIFs) are evaluated for both the cases of the EMPS model (magnetic zone is smaller or greater than electric zone). For evaluation of inner and outer electric and magnetic zone lengths (MZLs), an iterative approach is applied to solve the developed two non‐linear equations. Also, to implement the semipermeable crack‐face conditions, a bisection iterative method has been applied. Based on the developed closed form solutions, numerical studies are presented for standard fracture parameters with respect to crack propagation velocity, electrical loading and inter‐crack space distance. This study shows that electric displacement and magnetic induction defined over the crack‐surface for semipermeable conditions decrease whereas the numerical values of saturated zone lengths, COD, COP, COI, and LSIFs increase with increasing crack propagation velocity. Moreover, for both static and dynamic cracks problems, the significant crack‐interaction effects have been observed on all the studied fracture parameters except the crack‐face conditions.

Published: January 2024

AbstractAlkaline water electrolysis is the important pathway for the green hydrogen production, where oxygen evolution reaction (OER) is the rate-limiting step due to the sluggish reaction kinetics. Transition metal heterogeneous catalyst is the kind of important OER catalyst for alkaline water electrolysis due to its good performance, low price and environmental friendliness. In this work, the porous sulfide nickel@nickel iron alloy catalyst (i.e. NM/NS@Ni3Fe) is prepared by the designed high-temperature vulcanization and multi-step electrodeposition method. The NM/NS@Ni3Fe catalyst exhibits an outstanding OER performance in an alkaline environment, with a low potential of 1.53 V at high current density of 1000 mA cm−2 and a low Tafel slope of 89 mV dec−1. The excellent OER performance is attributed to the unique electronic structure of Ni3S2/Ni3Fe heterogeneous interface and the catalyst layer with porous structure. The results indicate that Ni3S2 provides good electronic conductivity and the low electronegativity S atoms increase the formation of oxygen vacancies, which effectively improves the OER performance. In addition, the hydrophilic and porous structure of the electrode facilitates bubbles release and electrolyte flow at high current density. It provides the guidance for the design of porous heterogeneous OER catalysts with good-performance.

AbstractHigh temperature heat exchanger is a crucial equipment in the BOP of SOFC. Replacing the commonly used metal materials with high-temperature resistant SiC ceramic materials for the manufacturing of SOFC high-temperature heat exchanger is a revolutionary technology with great application potential. This paper focused on SiC-based cathodic air preheater which is a novel SOFC high temperature heat exchanger, and firstly investigated the coupled radiation-conduction-convection heat transfer characteristics between flue gas and air at extremely high temperature conditions. The DO model in ANSYS Fluent was utilized to analyze the radiation heat transfer characteristics of high-temperature flue gas and the effect of gas absorption coefficient, and the simulation results were compared with the S2S model and non-radiation model. The results showed that radiation heat transfer cannot be ignored at high flue gas inlet temperature. With flue gas inlet temperature in the range of 800–1100 °C and low air/flue gas flow rate ratio, the gas radiation heat transfer and the effect of flue gas absorption coefficient can be ignored.
Numerical Investigation of Combustion Characteristics of the Port Fuel Injection Hydrogen-Oxygen Internal Combustion Engine Under the Low-Temperature Intake Condition

Published: January 2024

AbstractThe flammability limits of the hydrogen-oxygen mixture are extremely wide, and the ignition energy is low. Due to its excellent combustion properties, the hydrogen-oxygen mixture can be used as fuel in internal combustion engines (ICEs). However, the combustion of hydrogen-oxygen mixture is too intense, which results in limited research on its application in ICEs and is limited to low-temperature conditions in aerospace. This research aims to numerically discuss the coupling effects of equivalence ratio and ignition timing on the port fuel injection hydrogen-oxygen ICE under the low-temperature intake condition. The three-dimensional geometric model of a single-cylinder ICE was established using the CONVERGE software and validated against the mean in-cylinder pressure and reaction mechanism. The results indicate that adjusting equivalence ratio and ignition timing operating parameters is beneficial for controlling the temperature and pressure in the cylinder within a reasonable range during the total combustion process. In general, under the low-temperature intake condition, adopting a high equivalence ratio and optimal ignition timing strategy improve the combustion process and power performance of the port fuel injection hydrogen-oxygen ICE.

Published: January 2024

AbstractThe compatibilization of graphene/epoxy resin composites and carbon nanotube CNT/epoxy resin composite were studied based on the crystallized models with the molecular dynamics simulation in this paper. The effect of resin formula on compatibility parameter of carbon matrix was studied, and the combination of diglycidyl ether of bisphenol A (E51) resin with isophorone diamine (IPD) as the hardener achieved the best result. Further, the graphene/epoxy resin composite were constructed to investigate the effect of functional groups on components compatibility, conclude hydroxyl, carboxyl and amino. It was found that the functional groups had strong impact on compatibility parameter of graphene and CNT, whereas carboxylated graphene exhibits the best compatibility with the resin. This is due to the strong electronegativity of the carboxyl group, which induces a molecular interaction with the epoxy groups at the end of E51. The present study is expected to provide significant molecular insight into the relationship of compatibility between carbon matrix and epoxy resin for fuel cell composite bipolar plates.

Published: January 2024

AbstractMulti-electrolyzers system is an effective method to address the problem that the lowest operating point of the alkaline water electrolyzer still is high when the water electrolysis system is coupled with renewable energy. This work proposed different configurations of nominal power and operating strategies of electrolyzers for an off-grid isolated stand-alone wind hydrogen system. The configurations contain different nominal power of electrolyzers rather than the same nominal power. An equal load strategy is proposed and simulated based on the operation characteristics of the alkaline electrolyzer. This strategy could reach the 99% of energy absorption rate.

Published: January 2024

AbstractWith the growing energy crisis and environmental problems in recent years, the green energy technology represented by fuel cell technology has been developing rapidly. Since air contains a large amount of nitrogen that does not participate in the reaction, the circulation of nitrogen in the cathode gas supply system will increase the power consumption of the air compressor, resulting in a lower net power output of the fuel cell system. In order to improve the output performance of the fuel cell system, a new fuel cell cathode gas supply system with oxygen and air mixing is proposed in this paper, and the research results show that this topology can effectively increase the output power of the stack and reduce the power consumption of the air compressor, which can eventually increase the net power of the system to more than 10%. This study provides an effective theoretical guide for the design of fuel cell system and the optimal matching of cathode gas supply system.

AbstractForced-convection open-cathode proton exchange membrane fuel cells have attracted much attention due to simple structure. The fan, as an important component of the stack, significantly influences the mass density and performance of the stack. Therefore, it is crucial to select the appropriate fan. In this study, the performance of stacks with different fans is compared and the optimal duty ratio and temperature of stacks under different load currents are determined. The experimental results show that excessive air volume reduces the performance of the stack, and the parasitic power should be taken into consideration. Additionally, the weight of the fan is is a significant factor that needs to be considered. Furthermore, the experimental results show that under the condition of sufficient air supply, the appropriate temperature rise is conducive to the improvement of stack performance. In order to reduce the weight of the stack, it is necessary to choose a reasonable fan.

AbstractMicro energy networks are an important way to achieve the “carbon neutrality” goal. To further explore the potential of energy conversion in reducing carbon emissions, this article proposes an optimized operation model for micro energy networks with refined power-to-ammonia conversion. Based on the operation model considering carbon trading and comprehensive demand response, an optimization model for micro energy networks with refined power-to-ammonia conversion is established, with the objective of minimizing the system’s operating cost and carbon emissions. Utilizing examples, various micro-source energy dispatch conditions are analyzed and the carbon emission costs, as well as the overall operating costs of the micro energy network, are calculated. The results show that compared with power-to-hydrogen conversion, using power-to-ammonia conversion in micro energy networks can effectively reduce system carbon emissions, with a decrease of 7.88% and a total operating cost reduction of 5.36%. This verifies the feasibility of the model and demonstrates that improving energy utilization can achieve the synergistic operation of the system’s economy and low-carbon emissions.
