Synthesis, characterization, and application of silica aerogel thin films prepared via surface derivatization: A comprehensive study on micro-silica nanofilms for enhanced photoelectric conversion efficiency in photovoltaic solar cells
Authors: Che Yan
Published: June 2024

Silica aerogels are nanoporous materials with exceptional optical and physical properties, making them promising candidates to enhance solar cell efficiency as antireflective coatings. This study synthesized hydrophobic silica aerogel thin films under ambient conditions and characterized their porous structure, surface morphology, and optical performance. The films were deposited on monocrystalline silicon solar cells to assess their impact on photovoltaic properties. A two-step acid/base catalyzed sol-gel process was utilized, followed by solvent exchange and surface modification with trimethylchlorosilane. Structural analysis via SEM revealed successful deposition of crack-free films when aging occurred in an ethanol environment. The aerogel displayed considerable specific surface area (115 m2/g), porosity (77.92%) and surface roughness (55-78%) along with a low refractive index (1.05), benefiting light harvesting. Preliminary solar testing showed increased output voltage with a 0.2 mm aerogel coating versus a bare cell. Further IV measurements demonstrated enhanced charge transport and conversion efficiency for the treated cell. The aerogels antireflective and light-trapping effects appear to improve photon absorption. This initial research validates the potential of ambient pressure-synthesized hydrophobic silica aerogels to increase the performance of silicon photovoltaics cost-effectively. Further optimization of film thickness and morphology could realize higher efficiency gains.
Truss support for additive manufacturing
Authors: Lin Sirui
Published: June 2024

Additive Manufacturing (AM), commonly known as 3D printing, represents an innovative technique for crafting objects by layering materials based on digital blueprints. This method offers a range of advantages, encompassing tailored customization, rapid prototyping, and the fabrication of intricate forms using an array of materials. The process involves the gradual deposition of successive material layers to create the final product. Notably, a robust support structure is indispensable, particularly in 2.5-axis printing, to avert deformities, dislocation, and the potential collapse of the printed model. However, prevailing support designs in AM processes, such as columnar supports, give rise to challenges linked with the wastage of materials and time-intensive procedures. To counter these issues, this research undertakes the development of an innovative truss support methodology. Through substantiated findings, the author showcases how integrating a truss support structure can enhance support strength without necessitating extra material consumption. This revelation underscores the key potential of truss structures in AM, promising amplified efficiency and diminished costs in practical applications.

The change of renewable energy and zero-carbon economy in an anthropogenically warming climate
Authors: Chen Zhengyang
Published: June 2024

Anthropogenetic global warming has led to increasingly significant environmental issues, biodiversity losses, and socioeconomic impacts. There is a rising demand for transition from fossil fuels to renewable energy (RE), reducing carbon emissions, and thus realizing zero-carbon economy. Nevertheless, it remains a challenge to achieve the carbon-free economy and mitigate global warming, without fully understanding the ongoing RE development. The major objectives of this research are to (1) investigate the changes of different RE types compared with fossil fuels in the U.S., U.K., Mexico, Canada, and China; (2) examine the relationships between RE, temperature anomalies, and GDP; and (3) propose potential strategies for zero-carbon economy and climate change. The annual mean energy, temperature, and GDP data in these five selected countries during 1980 to 2021 are collected for analysis, and their relation-ships are addressed through Pearson's correlation analysis, along with significance test. The results suggest an increasing trend of RE and rising RE-fossil fuels ratio during the past four decades. All five countries either showed exponential or linear increasing trends in GDP and RE. The correlation analysis suggests a significantly positive correlation between RE and GDP in both countries. For example, different from the U.S., the synchronized growth in RE and fossil fuels in China leads to a significantly positive correlation between these two. All five countries provide their unique data of renewable development, which can stimulate the research and enable further study. This study will shed light over possible strategic plans for an optimized use of renewable energy, ensuring below 1.5C temperature rise, and reaching carbon neutrality by 2050.
A review of applications of handling particular materials under microgravity
Authors: Chang Bohao
Published: June 2024

Microgravity research has been carried out by researchers around the world for many years. By using space flight experiments (the International Space Station) and ground-based experiments (the Microgravity Sounding Rocket, a landing tower, and weightless aircraft), the investigations under microgravity conditions are thought to be beneficial to human life in terms of chemical, physical, and biological aspects, and more. It has become a very important tool for scientific research and industrial applications today. This paper reviews the work in this area with special reference to the applications in chemical engineering processes such as particle conveying and flow and material science under different gravity levels, including microgravity environments. It has been demonstrated that gravity has a strong effect on particle conveying and flow. Reduced gravity can make materials more cohesive, which further influences particle conveying. Actually, the effect of gravity can be ignored when the gravity level is less than 0.0001g. In the field of material science, the microgravity environment can accelerate the formation process of materials, like crystal growth, and then lead to a better structure.
Technical analysis of seawater desalination
Authors: Zhu Siyuan
Published: June 2024

As the population grows and the economy thrives. The amount of edible water has decreased, and this phenomenon is raising awareness about water supply. Dumping salt into a bucket of water may seem like no big deal, but reversing the process is a lot more complicated than people might think. Seawater desalination technology is also a hot topic of research. There are two major techniques for desalting. One is distillation, and the other is reverse osmosis filtration. This essay mainly discusses how the two techniques work and what benefits human beings can possibly obtain from the future development of such technology based on existing literature and statistical data, namely prosperity. The result shows that the reverse osmosis process uses less energy in comparison to thermal distillation. However, desalination is not as easy as we expected. Regarding energy consumption and cost efficiency, scientists have to maintain high productivity while reducing the impact on the environment.

Authors: Zhang Shitong , Yang Hua , Liu Danyang
Published: June 2024

A recommendation system is an information filtering tool that helps users find the products or services they need from a large amount of information. However, collaborative filtering is quite sensitive to data sparsity and cold start problems, and it may encounter certain difficulties when handling outliers. To address the issue of handling outliers, it is necessary to study and improve the existing collaborative filtering techniques. This paper proposes a personalized recommendation algorithm that integrates collaborative filtering with the Spearman rank correlation coefficient. By combining collaborative filtering and the Spearman rank correlation coefficient, the algorithm uses the latter to handle outliers, making it more suitable for nonlinear relationships. This hybrid recommendation algorithm can better handle outliers while maintaining personalized recommendations, providing a basis and reference for personalized recommendations.

Authors: Zhou Hang , Li Juan , Cao Tingting
Published: June 2024

In current agricultural planting, returning straw to the field can effectively improve the physical properties of the soil, increase the organic matter content, enhance the soil's aggregate structure, and further improve soil fertility. This is beneficial for the sowing and production of the next crop, helping to increase yield and quality. However, currently in China, straw treatment is still mainly simple methods such as burning. Some people think that the straw returning to the field is cumbersome, so it has not been widely applied in the agricultural planting process. The article first analyzes the significance of the promotion and application of straw returning to the field technology, then explores the main factors affecting the application of crop straw returning to the field technology, and finally proposes several effective measures for technology promotion.

Published: June 2024

Nationally, the 4-H Youth Development Program utilizes more than 350,000 adult volunteers annually, and 25% of the nation’s K-12 students identify as Hispanic or Latino; however, there is a dearth of published literature on Latino volunteerism in the 4-H Youth Development Program. Developmental relationships, a critical component of realizing youth development outcomes, are enhanced when adults and young people share cultural values and identity markers. The Cooperative Extension System has an obligation to reach a diverse audience and ensure program participation reflects the demographics of the communities in which youth live. We review the literature on Latino volunteerism in 4-H, share what we learned implementing the 2016-2019 University of California 4-H Latino Initiative, and provide our reflections and recommendations.

Authors: Balcı Halil , Sapancalı Faruk
Published: June 2024

İlk ortaya çıktığı dönemde sadece en alt gelir grubunda yer alan işçilerin ekonomik ve sosyal risklere karşı korunmasını amaçlayan asgari ücret uygulamaları sonrasında işgücü piyasalarının bütünün düzenlenmesinde etkili bir araç halini almıştır. İşgücüne çalışması karşılığında ödenebilecek en düşük ücreti ifade eden asgari ücret ekonomik, sosyal ve siyasal boyutlara sahiptir. Bu özellikleri kendisini emek ve sermaye arasındaki çatışmanın önemli bir alanı haline getirmiştir. İşçi ve ailesinin ihtiyaçları ile işverenlerin ödeme kapasiteleri arasında bir dengeyi ifade etmektedir. Özellikle ekonomik istikrarsızlık, buhran ve kriz dönemlerinde asgari ücret konusu sıklıkla gündeme gelmektedir. Asgari ücret bir yandan bu koşulların ortaya çıkardığı risklerin bertaraf edilmesi ve ekonominin tekrar istikrarlı hale getirilmesi için önemli bir araçtır. Asgari ücret bir yandan toplumun en yoksul kesimini korurken bir yandan da marjinal tüketim eğilimi yüksek olan bu kesimin tüketim harcamaları yoluyla toplam talebi artırarak sürdürülebilir bir ekonomik büyüme için dayanak noktası oluşturmaktadır. Avrupa Birliği, asgari ücret konusunda birlik düzeyinde uzunca bir süre düzenleme yapmamıştır. Bununla birlikte 2008 krizi, Covid Pandemisi ve en son da çevre ülkelerde ortaya çıkan savaş koşulları AB ülkelerinin istikrarlı ekonomilerini ve uzunca bir süredir uyguladıkları sosyal refah devleti politikalarını sekteye uğratmıştır. Kısa sayılabilecek bir zaman diliminde ortaya çıkan bu gelişmeler sonucunda AB asgari ücret ile ilgili Birlik üyelerinin katılımıyla ve Birlik üyesi bütün ülkeleri bağlayan bir yönerge hazırlamıştır. Çalışmada ilk olarak AB’nde asgari ücret ile ilgili geçmiş düzenlemeler ele alınmış sonrasında ise 2022 yılından kabul edilen “Yeterli Bir Asgari Ücrete Yönelik 2022/2041 Sayılı Yönerge” ortaya çıkış gerekçeleri, düzenlenme ve uygulanma süreçleri bağlamında ele alınıp, incelenmiştir.

Published: June 2024

The objective of this research is to improve equipment used for conveying raw material in the construction material industry and establish standard procedures for maintenance by applying Theory of Inventive Problem Solving (TRIZ). Research methodology consists of 1) studying the maintenance system of raw material conveying equipment of the case study company 2) collecting data and prioritizing problems using a Pareto chart, 3) setting goals, 4) analyzing the causes of the problems with Why-Why analysis and 3 GEN techniques, 5) concluding the results. Results from the study in 2022 showed that problem occurred at sieves and vibrator base used for filtering raw materials resulting in a high maintenance frequency of 28 times. The causes of the problem are the improper shape of the sieves and the installation position of the sieve vibrator including the carelessness of the worker to turn off the vibrator. This research solved the problems by applying TRIZ as guidelines for designing new sieves and applying Total Productive Maintenance (TPM) in establishing standard procedures for maintenance. The results of the improvement during May-November 2023 showed that the frequency of sieves maintenance decreased to 3 times equivalent to 6 times per year approximately, achieving the goal of less than 14 times/year. The MTBF increased from the original 171.67 hours to 1,055.91 hours and the MTTR decreased from 3.04 hours to 2.55 hours. It can be concluded that TRIZ can be applied to improve the material conveying equipment by significantly reducing the maintenance frequency.
Extraction Of Temperature Fields From PIV Data Of Turbulent Rayleigh-Bénard Convection Using DNS
Authors: Bauer C. , Schiepel D. , Wagner C.
Published: June 2024

To gain insights into the dynamical processes that govern the problem of turbulent Rayleigh-Bénard convection, information about the temperature field---next to the velocity field---is required. In the present study, we exploit the governing flow equations to extract the temperature field from a velocity field measured via tomographic particle image velocimetry. The methods used within this study are derived from algorithms originally used in the framework of direct numerical simulations. First, we enforce the divergence-free condition on the measured velocity field using a fractional-step method based on a Poisson equation. Second, we extract the temperature field from the velocity field via the momentum equation. Third, we extract the temperature field from the velocity field via the solution of the stationary convection-diffusion equation. The extracted velocity field---together with the corresponding divergence-free velocity field---can serve as an initial condition for a direct numerical simulation of the problem. Validating the extraction method based on the stationary convection-diffusion equation with data from direct numerical simulations shows a good correlation coefficient between the extracted and the simulated temperature field (0.86). Although the third method incorporates the ambitious assumption of stationarity, temperature fields are successfully extracted from the measured velocity fields. However, with a correlation coefficient of 0.57, the agreement between the average extracted temperature field and the average temperature field measured in a subvolume of the flow domain is somewhat less than the one found in the simulated data. The latter is presumably attributed not only to the extraction method, but also to the underlying measurement data. Thus, an increase in measurement accuracy in future applications is likely to improve the accuracy of the extraction methods as well.

STEAM education is often presented as STEM, resulting in the loss of blended arts integration. The researchers present rationale for including the arts to provide students with interdisciplinary and transdisciplinary curricula that promotes increased creativity and emotive connections to learning. Blending of the arts in STEAM provides students with a greater depth and breadth of critical-thinking, creative-thinking, and social-emotional connections to content. The social capital and emotive connections students construct in STEAM learning present educators with opportunities to entwine mindfulness practices to empower students to develop confidence and competence in their STEAM abilities. Entwining STEAM, self-regulation, and mindfulness provides both a canvas and laboratory of aesthetic, holistic learning of the mind and spirit. The researchers provide instructional and clinical professional practices as well as recommendations for STEAM as a construct for not only providing opportunities for students to engage in cognitive progression, but also to assist learners in developing social, emotional, and behavioral skills for lifelong regulatory and mindfulness learning.
The Construction of Attitudinal Meaning in Response to Food Advertisements: Six Case Studies
Authors: Mohammed Alhuthali
Published: June 2024

Emotional responses are an important part in the response to an advert. Often this is related just to the information directly provided but sometimes it relies, either intentionally or not, on information derived from wider social contexts and knowledge. In Appraisal Theory, this part of the process is described as Appreciation. This study considers six adverts and how different parts of Appraisal Theory may be key to their understanding and whether there is a link between advert design and the adopted meaning making process.

Authors: Khogali Hind Abdelmoneim
Published: June 2024

In the last 20 years, the world has seen increasing use of Artificial intelligence (AI) in many disciplines, one of these disciplines is Architecture. This research aims to study the effect of using AI in Architecture schools, especially design studios, in which phase, and in what percentage.

The methodology of the research is applied for AI programs in four main design steps: The concept phase developing the design, coloring and developing the elevations, rendering phasing by using the AI, and distributing a survey to Design 7 students to register their responses using AI in Architecture design selected case studies from students work was selected to reflect the research works.

The results from the survey show that the students achieved applying AI in concept development by 75%, in the development design process by 72.54%, in coloring by 50%, in rendering by 48%, sustainability by 70%, and in developing building form and structure by 72.3%.

The conclusion of the research recommends applying AI in the whole design process including concept development, developing design process, coloring, rendering, form, and structure under the teacher's supervision, and recommends teaching AI as a course in architecture engineering colleges.
Archive and site: The ghost of Peter Eisenman’s 1978 Cannaregio Ovest project in Venice
Authors: Lanuza Felipe
Published: June 2024

In this paper, I discuss Peter Eisenman’s unbuilt proposal for the Cannaregio Ovest district in Venice, and develop a speculative reading linking the project’s archive and the site. I account for different absences involved to visually represent the archive and site in a multi-layered and open-ended relation. Through a critical and creative reading of the archival material of the project and its underpinning discourse, in the light of the present of both its intended location and the debates around Venice’s built heritage, I reveal the potential of the archive as a tool to reimagine the experience of the city and to inform a critique of its conservation.

Published: June 2024

Urinary tract infections resulting from Escherichia coli, are prevalent and have become increasingly difficult to treat due to antibiotic resistance. This study aimed to explore the potential of propolis extract from beehives in Algeria’s Tiout region as a natural antibacterial agent against E. coli CECT_515. The phytochemical composition, antioxidant activity, and antibacterial action of the extract has been evaluated and compared to four synthetic antibiotics, both in vitro and in silico. The propolis extract had high levels of total polyphenol and total flavonoids, regarding its antioxidant properties, the extract showed an important ability of DPPH radicals scavenging, as determined by its IC50 value of 330.08±13.35 μg/mL. The excerpt showed important antibacterial efficacy against Escherichia coli, as demonstrated with important inhibition zones. The extract’s inhibitory effects were compared to four synthetic antibiotics, including gentamicin, pipemidic acid, cefazolin, and colistin, molecular docking analysis revealed that the propolis extract interacted with the active site of beta-lactamase, a protein responsible for antibiotic resistance, and showed binding affinities and conformational stability during molecular dynamics simulation for 250 ns. Overall, the results suggest that the propolis has significant antioxidant and antibacterial properties and could serve as a promising natural alternative to synthetic antibiotics for the treatment of E. coli infections.

In this work, a successful cryopreservation method of date palm tissue cultures by vitrification was established. Callus and somatic embryos of three date palm cultivars were exposed to dimethylsulfoxide (DMSO) and Plant Vitrification Solution 2 (PVS2) for different durations before plunging into liquid nitrogen for cryoprotection. After freezing phase, the cryopreserved cultures were thawed and cultured on recovery media. Among different times of exposure to DMSO (10%), 60 min gave best results of survival and regrowth of the date palm tissue cultures. Regarding recovery, ‘Zaghlool’ cultivar gave the highest values of callus fresh mass (0.5 g) and growth value (1.00). Also, the highest differentiation percentages (75%) and number of proliferated shootlets (8.50) were recorded with ‘Zaghlool’ cultivar. Concerning PVS2, survival and regrowth gradually increased as exposure time increasing till 30 min and then decreased. Unlike of callus cultures, the survival and regrowth rates of somatic embryos were relatively higher at all PVS2 exposure time. With regard to recovery, the genotype effect took same trend in cryopreservation of callus cultures, since ‘Zaghlool’ was superior in growth parameters in comparison to the other two cultivars. On the other hand, genetic stability of the cryopreserved date palm tissue cultures was assessed using ISSR markers. Among four screened primers, three gave monomorphic bands; all of these banding profiles were similar to those of non-cryopreserved cultures. Generally, the results of ISSR showed high genetic similarity suggesting that cryopreservation using vitrification does not affect genetic stability of date palm tissue cultures. The results of this study demonstrated PVS2 was more effective in cryoprotection of date palm tissue cultures compared with DMSO and cryopreservation by vitrification is a suitable tool for conservation of genetic stable date palm germplasm.

Published: June 2024

The European Union (EU) has been actively combating climate change for decades, and in 2019 it introduced its most ambitious project to date, the European Green Deal (EGD). EGD includes a variety of policies and strategies aimed at mitigating the adverse effects of climate change, foster an economic growth, and promote social equity. Recently, the European Commission has been contemplating the development of the European Blue Deal (EBD), which aims to address the growing water crises and water insecurity issues within the EU. Similar to the EGD, the EBD would encompass all sectors of the European economy, seeking integrated solutions to these pressing environmental problems. This review aims to assess the progress of the EGD, evaluate the objectives of the EBD, and provide insights into the factors that could either catalyze or hinder their effective and harmonious implementation. The concept of a "Teal Deal" (a combination of the blue and green color) which combines elements of both the EGD and the EBD, is explored, with particular emphasis on its implications for the agrifood sector. Here we argue on the necessity for a holistic approach to agricultural sustainability, rapid advancements in renewable energy, the adoption of crop diversification strategies, and the development of effective international policies to ensure global cooperation and support for these transformative initiatives. By addressing these key areas, the EU can make significant strides towards achieving its environmental and economic goals.
