Authors: Fan Tianlong
Published: November 2023

With the popularity of building construction worldwide, building design, construction technology and quality are faced with inherent deficiencies and may be hit by disasters. Therefore, the diagnosis and reinforcement of building structure has become a major problem to be solved urgently in the current building construction. This paper introduces simple detection methods of different building structures and reinforcement techniques under different conditions. In the part of detection methods, various basic detection methods of normal building structure are studied. Then, a special damage appearance is discussed. Besides the traditional electronic imaging method to detect cracks, a special method is proposed to solve the crack problem, namely Min-Max Gray Level Discrimination (M2GLD). This method can improve the detection accuracy and reduce the influence of human factors. At the same time, several different reinforcement techniques are proposed, including traditional reinforcement techniques and advanced reinforcement techniques. This paper introduces the traditional technology of ancient timber structures and the technology of spraying and external bonding FRP to enhance flexural, shear and compressive strength.

Authors: Wang Weizhi
Published: November 2023

With the rapid development of integrated circuit (IC) technology, the size of devices has been continuously shrinking. While this trend has led to increased integration density, improved device reliability, and reduced costs, it has also resulted in performance degradation of metal-oxide-semiconductor field-effect transistors (MOSFETs) due to the short channel effect (SCE). This paper provides a comprehensive review of the most recent techniques that can mitigate the short channel effect in MOSFETs, with a focus on semiconductor materials and device structures. These techniques include decades-long advancements in doping and high- dielectric materials, as well as emerging structures such as Fin field-effect transistors (FinFETs), Gate-all-around field-effect transistors (GAAFETs), Forksheet field-effect transistors, and complementary field-effect transistors (CFETs). This paper can greatly assist researchers in establishing a theoretical foundation, identifying research problems and voids, and identifying hot spots and trends in short channel effect research through a comprehensive analysis of the existing research literature.
Fast fabrication of high entropy oxides electrodes for flexible zinc-ion batteries with high electrochemical performance
Authors: Nie Yuqi
Published: November 2023

The expanding world population, increasing energy demand, and looming climate change urge the development of a sustainable energy future while safeguarding our vulnerable environment. To build a new flexible battery system, high entropy oxides are used as electrodes based on zinc-ion batteries. The battery system with the best electrochemical performance can be determined by a series of experimental designs. Here in I propose to develop a HEO electrode using a fast and clean laser deposition method. A series of tests are designed to verify the degree of performance improvement. In the further research planning, the electrode material can be produced with a metal removed from the HEOs alone and using the same synthetic method and performance measurements to determine the roles of each metal in the HEOs. Additionally, the anions in the HEOs can also be varied to study the impact of various anions on the cell's electrochemical performance. Finally, the particle size of the HEOs can be varied to establish a correspondence between particle size and electrochemical performance to facilitate the selection of the optimum particle sizes. The experimental results can further provide a theoretical basis for the commercial application of zinc-ion batteries in flexible power systems.

Published: November 2023

Nano-material refers to small particles with a size within 100nm. It has received widespread attention from many industries because of its different performances of the light, electricity, heat and other industries that are different from conventional materials. In recent years, new nanomaterials such as AgNWs and graphene have attracted considerable attention worldwide due to their extremely high electrical conductivity and light transmission. However, AgNWs are less stable and graphene is less homogeneous in terms of resistance; thus, improving the performance by hybridizing the two composites has become a major research goal. In this paper, the synthesis methods of graphene and graphene/AgNWs composites are presented, and various properties of the composites, such as electrical conductivity, flexibility, and stress-strain capability, are also presented. The comparative analysis of these properties concludes that the excellent properties of graphene/silver nanowire composites have great potential for development and still need to be explored continuously.

Authors: Wu Chunlin
Published: November 2023

At present, the market pressure strain sensors mainly include intrinsic conductivity, composite conductivity, and flexible metal conductivity. Most of the strain sensors can met various basic requirements such as strain sensitivity and mechanical properties. However, biocompatibility and the ease of use are still areas to be explored and improved. This paper proposes a novel strategy to fabricate a kind of self-adhesive and conductive hydrogel using natural biomacromolecule gelatin, tannic acid (TA) and conductive polymer PEDOT: PSS. The sensor is biocompatible, nontoxic, and can be directly attached to the skin without the use of adhesive tape, and sufficiently large electrical signal response can be collected under stress. The presence of tannic acid forms a cross-linking network with the gelatin in the organic hydrogel, which can effectively increase the toughness (which can reach 203.62 kPa/m3). PEDOT: PSS provides the conductivity for the hydrogel, and hydrogel with 0.3wt% PEDOT: PSS content have a conductivity of about 2.1ms/cm. Therefore, this study found the possibility of making a flexible electronic element by using a composite of PEDOT: PSS, gelatin, and TA.

Authors: Xu Jiashu
Published: November 2023

Federation Internationale de l'Automobile (FIA) has announced a Power Unit (PU) Regulation change for its Formula 1 (F1) Championship that will become valid from the 2026 season in pursuit of carbon neutralization and a higher commercial value. The change includes a full switch to sustainable fuel and an increase in the power of the electric power output to the cars axles but removed energy retrieving and recovery from the turbocharger. The choice to use fully sustainable fuel will lead to a richer burn. On the other hand, the increase in the hybrid system capacity will outweigh the removal of energy retrieving and recovering from the turbocharger and cause an overall increase in thermal efficiency. Also, the changes are bringing a cost reduction for PU suppliers, which is an attraction for them. The increase in electric power will also integrate the car with new driving characteristics. This paper focuses on respective reviews of the 2023 and 2026 F1 PU Technical Regulations and gives an evaluation of the process for the improvements.

Authors: Zhang Lihong
Published: November 2023

In recent years, global warming has been an ongoing concern for experts, and the cause of this problem is the over-reliance on fossil fuels, so finding a new source of energy that can replace traditional fossil fuels is essential at this stage. In terms of hydrogen production, solar hydrolysis is a promising method for converting sunlight into renewable, sustainable, and green hydrogen energy. The most representative pathway for converting solar radiation into molecular hydrogen is photovoltaic chemistry (PEC). In terms of hydrogen storage, researchers have identified the potential of a new type of hydrogen storage vessel, the "hybrid hydrogen storage vessel," which combines an aluminum-carbon fiber reinforced plastic (Al-CFRP) composite vessel with a hydrogen storage alloy. An evaluation of this system has shown that the hybrid hydrogen storage vessel has advantages over conventional hydrogen storage technologies in terms of volume and weight of stored hydrogen. In terms of hydrogen applications, hydrogen-fueled electric powertrains offer a solution for long-distance driving using clean energy, whereas battery-powered vehicles are plagued by range limitations, which is a shortcoming in hydrogen applications. This paper critically examines the potential of hydrogen as a sustainable energy source and presents three aspects of hydrogen technology, respectively its production, storage and application. This essay highlights the importance of chemical engineering principles in optimizing the production, storage and utilization of hydrogen energy for a clean, sustainable energy future.

Developing new energy storage technologies is the foundation for advancing renewable energy. Among them, the development of electrochemical energy storage technology has received widespread attention. Due to its high energy density, lengthy cycle life, and environmental friendliness, lithium-ion batteries (LIBs) are being utilized extensively in everyday life. With a similar structure to LIBs, sodium-ion batteries (SIBs) are also promising for broad use in the new energy sector due to their abundant Na supplies and considerable cost benefits. In addition to introducing typical battery types and their benefits and drawbacks, this paper investigates the structures and operational concepts of LIBs and SIBs. SIBs have the advantages of low cost, abundant resources, and faster charge-discharge rates. However, they have lower energy density and require larger volume and weight. On the other hand, LIBs have a higher energy density, and more stable cycle life, but also have disadvantages such as poor safety, high cost, significant environmental impact, and destructive mining processes. The paper also focuses on the industrialization progress of SIBs by internationally renowned new energy companies such as Contemporary Amperex Technology Ltd. (CATL) and Natron Energy, highlighting the advantages of SIBs in the field of energy storage.

Authors: Sun Hongyi
Published: November 2023

Reinforced concrete is an important construction material that is of great research value in industry and science. Today, it is one of the most widely used materials in high-rise buildings around the world. However, at the same time, this kind of construction production activity has a non-negligible impact on the earth's environment, mainly in terms of its consumption of environmental resources and carbon dioxide emissions. Therefore, this paper focuses on how to reduce the burden of high-rise reinforced concrete buildings on the environment and achieve sustainable development. Through reading and analyzing the literature, it could be inferred that the use of high strength concrete reduces the volume of structural components as well as making the building more impermeable, thus reducing the amount of material that needs to be manufactured during the life cycle of the building, which can efficiently cut carbon emissions and energy consumption in high-rise buildings.

Published: November 2023

As one of the most critical areas in a hospital building, the rationalization of the lighting environment is crucial for both patients and healthcare workers. This paper presents findings from field research and questionnaire interviews conducted in the Taiyuan ward, which reveal several issues with the current lighting setup, including low illuminance value, poor light uniformity, color temperature not meeting standard requirements, inappropriate selection and arrangement of light sources, and high proportion of lighting energy consumption. By analyzing factors influencing the humane and energy-saving aspects of the ward lighting environment, we explore a comparative simulation of the window-to-wall ratio and the form of shading inside the windows in the natural lighting system of the wards. Additionally, we consider the selection, placement, and control methods of lamps and lanterns for the artificial lighting system. Based on these findings, we propose a method for designing the light environment of hospital wards that accounts for both humane and energy-saving aspects, providing a technical means for optimizing the ward's lighting environment.

It was found that winter wheat of the Kraevyd variety, which was grown using alternative technology, was supplied with basic nutrients below the optimum during the growing season. Under resource-saving technologies, a lack of nutrients was observed in the second half of the growing season. The optimal and closest to the optimal supply of plants with nitrogen, phosphorus and potassium was during the growing season under intensive energy-rich growing technologies. Values, directionality and optimal parameters of accumulation of vegetative and dry mass by plants during their cultivation using technologies of different intensity are determined, and their relationship with productivity is shown. The accumulation of dry matter by crops of winter wheat during the growing season was closely correlated with the yield of this crop. There was a tendency to increase the closeness of the connection, which increased from the VI to the IX stage of organogenesis. Conclusions. It was established that, on average, for 2016–2020, the highest productivity of sowing winter wheat of the Kraevyd variety, 8.93 t/ha of the 1–2 quality class, was obtained under the intensive energy-rich technology, which involved the introduction of P80K100 + N80ІІ + N100IV + N60VII against the background of the introduction of by-products predecessor and integrated plant protection.

Aim. The research was to improve the technology of creating genetic diversity of samples obtained by remote hybridization of soft winter wheat and speltum wheat with usuing the biotechnological link in the selection scheme. Methods. Remote hybridization of plants is an effective method of obtaining new starting material. The research was conducted in the biotechnology laboratory of the Uman National University of Horticulture during 2018–2022. The initial maternal form was the soft winter wheat varieties Artemisia, Smuglyanka, Zolotokolosa and the parental form was the winter spelt variety Zorya Ukrainy. After hybridization, immature twelve-day-old embryos were planted on modified versions of MS nutrient medium and cultivated at 25 °C in the dark until macrostructures were formed. Results. The technology of obtaining hybrid material by remote hybridization of Triticum aestivum L. / Triticum spelta L. and its use in the selection scheme of the biotechnological link has been improved. Conclusions. A nutrient medium for the development of immature hybrid wheat germs has been developed. The highest yield of seedlings (40.0% on average by genotype) on the modified Murashige-Skug medium, which included 1,5 mg/l 6-benzylaminopurine, 0,5 mg/l indolylacetic acid, 1,0 mg/l gibberellin, 2,0 mg/l glutamine, 2,0 mg/l glycine, 0,5 mg/l serine, 100,0 mg/l meso-inositol, 50,0 g/l sucrose was recorded. It was noted that the induction of the development of biomaterial from hybrid immature embryos is a genetically determined factor. The possibility of obtaining genetic diversity of forms that can be used by donors of genes of individual traits using embryo culture was shown.

This research delves into the intricate relationship between financial metrics and stock prices within the Indonesian market context. Analyzing data from IDX 30 companies over the period 2018-2022, the study focuses on net profit margin, debt ratio, total assets turnover, and current ratio as key variables. The findings reveal that net profit margin exerts a positive significant influence on stock prices, highlighting the allure of profitable companies to investors. Conversely, the current ratio exhibits a negative impact, indicating the nuanced interplay between liquidity and stock valuation. Notably, total assets turnover does not significantly influence stock prices, emphasizing the multifaceted nature of investment decisions. Additionally, the study underscores the adverse effect of higher debt ratios on stock prices, reflecting investor concerns about financial leverage. These insights offer valuable implications for investors, analysts, and policymakers, enhancing our understanding of the Indonesian stock market dynamics and aiding in strategic investment planning.

Introduction: Myasthenic crisis is the most lethal complication of myasthenia gravis. Referral to an intensive care unit is crucial in managing the myasthenic crisis. Hereby, we report a case of a myasthenic crisis in a 30-year-old female who underwent plasmapheresis. The patient underwent a 12-hour procedure for plasmapheresis and was discharged to a normal ward the next day. Although plasmapheresis is costly, its efficacy should be considered as the main treatment for myasthenic crisis.

Case Illustration: Female, 30 years old, weighed 60 kgs, with myasthenia crisis. The patient came to an emergency department and was then intubated before being admitted to the intensive care unit. The physical diagnostic was normal and laboratory findings were leukocytosis. The patient was treated with normal saline, antibiotics, high-dose corticosteroids, and pyridostigmine. The patient was done plasmapheresis with synchronized intermittent mandatory ventilator mode. The patient was examined every 30 minutes. The physical examinations were relatively normal. The plasmapheresis procedure was ended in 12 hours.

From the literature, plasmapheresis was found to have significant results for myasthenia gravis compared to conventional therapy because of its blood separation technique to remove autoantibodies. The next day patient was extubated with normal physical examinations and normal laboratory findings. The patient then moved from the intensive care unit to the normal ward and outpatient on the third day of hospital stay. The patient was given oral medicine that included antibiotics, corticosteroids, and pyridostigmine.

Conclusion: From this case, we can see that plasmapheresis therapy has a really good outcome compared to other conventional therapy. However this therapy is expensive, so most healthcare providers don’t cover the payment. Hopefully, most hospitals and healthcare providers can cover up for this treatment to save many myasthenia gravis crisis.
