Application of Smart Polymer Materialsarts

With the wide application of polymer materials, the performance of ordinary polymer materials gradually cannot meet the shortcomings of use in special environments, such as limited strength, insufficient wear resistance, poor stability and so on. And can not adjust and repair according to changes in the environment. Therefore, the demand for intelligent polymer materials has gradually expanded, and has been applied to a variety of fields after research. This paper introduces the information and application of three kinds of intelligent polymer materials: targeting, shape memory and self-healing. Targeting is mainly used in cancer or other diseases that require precise drug delivery; The characteristics of shape memory can be applied to plaster and surgical sutures in the medical field, and can also be applied to the performance upgrade of traditional manufacturing industry. Self-healing can be used to improve the service life of composite materials by using different methods according to the requirements of different material use scenarios.

3D Printing with Self-Healing Materials and Applications

3D printing also called as the additive manufacturing. It is revolutionizing various industries by enabling the production of complex objects directly from digital models. This technology offers significant advantages over traditional manufacturing methods. Especially in reducing material waste and increased design flexibility. The range of 3D printing application contains healthcare to aerospace, reflecting its growing importance in modern society. Recently, 3D printing advancements have introduced in self-healing (SH) materials, it saved limitations related to the durability and repairability of printed objects. SH materials are categorized into external and internal systems. External SH materials use embedded healing agents that repair damage through chemical reactions, while internal systems rely on dynamic bonding within the material itself. This innovation not only extends the functional life of 3D printed items but also supports trends in mass customization and sustainability. This paper explores the mechanisms, types, and applications of SH materials in 3D printing, and mainly focus on their potential to enhance product longevity and functionality across medical, construction, and consumer goods sectors.

Enhancement of Additive Manufacturing Processes for Thin-Walled Part Production Using Gas Metal Arc Welding (GMAW) with Wavelet Transform

Additive manufacturing encompasses technologies that produce three-dimensional computer-aided design (CAD) models through a layer-by-layer production process. Compared to traditional manufacturing methods, additive manufacturing technologies offer significant advantages in producing intricate components with minimal energy consumption, reduced raw material waste, and shortened production timelines. AM methods based on shielded gas welding have recently piqued the interest of researchers due to their high efficiency and cost-effectiveness in manufacturing critical components. However, one of the most formidable challenges in additive manufacturing methods based on shielded gas welding lies in the irregularity of weld bead height at different points, compromising the precision of components produced using these techniques. In this current research, we aimed to achieve uniform weld heights along the welding path by considering the most influential parameters on weld bead geometry and conducting experimental tests. Input parameters of the process, including nozzle angle, welding speed, wire speed, and voltage, were considered. Simultaneously, image processing and wavelet transform were employed to assess the uniformity of weld bead height. These parameters were applied to produce intricate parts after identifying optimal parameters that yielded the smoothest weld lines. According to the results, the appropriate bead for manufacturing the part was extracted. The results show that the smoothest bead line is achieved in 27 V as the highest level of voltage, at a 90° nozzle position and the maximum wire feed rate. Parts manufactured using this method across different layers exhibited no distortions, and the repeatability of production substantiated the high reliability of this approach for component manufacturing.

BackgroundGhee, known as “roghane heiwâni,” or “Kermanshahi oil” is a traditional fermented butter-like product highly esteemed for its nutritional value. Ghee is prepared using traditional methods and has substantial potential as a reservoir of probiotic microorganisms. Previous research delved into isolating and identifying lactic acid bacteria (LAB) in Kermanshahi through culture and PCR sequencing. This study seeks to elucidate the microbial profiles and diversity within Kermanshahi using culture, Denaturing Gradient Gel Electrophoresis (DGGE), and sequencing methodologies.MethodsTwenty samples of Kermanshahi oil were meticulously gathered from diverse locales across Kermanshah province. These samples were cultivated under specialized conditions in MRS and M17 environments spanning 24 to 72 h. Following DNA extraction, amplification of the 16SrRNA gene sequences was performed, culminating in sequencing for conclusive identification of the isolates. Furthermore, the DGGE technique was directly employed to separate and identify various species present in the oil samples utilizing bioinformatics software.ResultsSequencing outcomes revealed a diverse array of microorganisms among the isolates, with Lactobacillus constituting 43%, Streptococcus comprising 27.6%, Enterococcus at 4.61%, and yeasts at 7.6%. Other species exhibited lower frequencies, encompassing Rhizobium, Bacillus coagulans, and Staphylococcus hominis.ConclusionsThe isolation of a diverse spectrum of probiotic microorganisms underscores their potential utility in the realm of industrial dairy product production. These findings allude to the possibility of integrating these valuable microorganisms, which have historically been associated with traditional products, into the contemporary dairy industry. As consumer interest in probiotic-enriched products surges, the insights gained from this study pave the way for harnessing the benefits of Kermanshahi-derived probiotics.

Lifestyle habits and openness to alternative tobacco products: insights from the Minerva Project

Abstract Background Recent studies have suggested that the use of alternative tobacco products (ATPs) is a significant predictor of cigarette smoking, particularly among young individuals. The present study evaluates the association between dietary patterns, specifically junk food consumption, and the willingness to try ATPs among non-smokers. Methods MINERVA (My changINg lifEstyles, our Research, and eVeryone’s heAlth) is an ongoing prospective international cohort study primarily focused on investigating the link between smoking habits and the dietary and lifestyle habits of participants. Subjects are given a web-based survey to report socio-demographic characteristics, dietary and lifestyle habits, smoking habits, and attitudes towards ATPs. This analysis concentrates on respondents from Italy who do not smoke traditional tobacco products. Results The survey included 7,535 respondents from Italy; of these, 40% (2,992 subjects) were non-smokers. Among the non-smokers, 219 (7%) were identified as fast-food consumers (defined as consuming fast-food at least once a week). Fast-food consumers were significantly more likely to consume junk food as snacks (87% vs. 62%) and were less likely to report daily consumption of fruits and vegetables. Notably, fast-food consumers were 2.5 times more likely to be willing to try ATPs compared to those who do not consume junk food (Odds Ratio [OR] 2.55, 95% Confidence Interval [CI] 1.68-3.88). Conclusions Junk food consumption has been identified as being associated with an increased willingness to use ATPs among non-smokers. This finding is significant from a public health standpoint, highlighting the crucial influence of unhealthy eating habits in fostering an interest in ATP use. Key messages • The Minerva study evaluates the association between dietary patterns, specifically junk food consumption, and the willingness to try alternative tobacco products among non-smokers. • The study underscores the public health importance of addressing dietary patterns alongside smoking habits.

A school-based intervention to foster adherence to the Mediterranean diet in adolescents: the PROMEDLIFE project

Abstract The need to maintain the production of local foods characterized by a high nutritional index, update traditional food production methodologies by developing attractive tech-based approaches, promote healthy eating habits that meet consumers’ preferences and acceptability, as well as reducing the complexity of supply chains (Farm to Fork) must be addressed to ensure food and nutrition security. This is especially true in Mediterranean countries undergoing dietary and nutritional changes that affect their inhabitants’ health while creating many socio-economic and environmental challenges. PROMEDLIFE aims to increase adherence to the Mediterranean diet through a multi-actor approach by encouraging the adoption of a healthy eating lifestyle while decreasing the environmental and economic impact of food production and processing. It also aims to attain optimal food communication and education through training programs that target primary and secondary students as well as their families, from children to older adults. A 4-week nutritional and sensory educational intervention in high school students involves frontal lessons, a web-app for families enrolled, and games on nutrients, food groups, balanced meals and various eating occasions, healthy and sustainable diets. In addition, adherence to the Mediterranean diet, nutritional knowledge, sociodemographic and lifestyle data, picky eating, and food neophobia are investigated. Including nutritional lectures in the school curriculum of high schools promotes knowledge acquisition about healthy diet. However, a period longer than 4 weeks may be necessary to translate this knowledge into improved eating habits. The project is still ongoing, and follow-up data collection will be performed. Final analysis, including data on picky eating and food neophobia, as well as overall eating behavior at follow-up, will allow an evaluation of possible long-term changes.

A Conceptual Framework of Navigating Digital Banking: How Gender Impacts Adoption Intentions in Klang Valley

Malaysian banking users have encountered negative experiences while adopting traditional bank services. Several customers and businesses face limited access to traditional banking products and services due to factors such as low or irregular income, bad credit, or a lack of conveniently located banks. The acceptability of digital banking products and services in Malaysia is currently unknown and inadequate due to the general lack of familiarity among Malaysians with the notion of digital banking. Conventional methods of analyzing consumer behavior, which primarily consider historical data and current resources, will not result in the achievement of branchless banking in the future. This paper presents a framework that examines how various factors such as performance expectancy, effort expectancy, social influence, facilitating condition, hedonic motivation, price value, and habit may influence behavioral intention. Additionally, the framework considers gender as a moderator variable. The results of this study are anticipated to expand the existing body of knowledge on behavioral intention and bring advantages to marketers and digital banking providers.

Probiotic Characteristics and the Anti-Inflammatory Effects of Lactiplantibacillus plantarum Z22 Isolated from Naturally Fermented Vegetables

Currently, there is increasing interest in the commercial utilization of probiotics isolated from traditional fermented food products. Therefore, this study aimed to investigate the probiotic potential of Lactiplantibacillus plantarum (L. plantarum) Z22 isolated from naturally fermented mustard. The results suggest that L. plantarum Z22 exhibits good adhesion ability, antibacterial activity, safety, and tolerance to acidic conditions and bile salts. We further determined the anti-inflammatory mechanism and properties of L. plantarum Z22 and found that L. plantarum Z22 could significantly reduce the secretion of pro-inflammatory cytokines, including interleukin-6 (IL-6), interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), and the expression of the pro-inflammatory mediator cyclooxygenase-2 (COX-2) protein in LPS-induced RAW 264.7 cells. In addition, L. plantarum Z22 also effectively inhibited the signaling pathways of nuclear factor κB (NF-κB) and mitogen-activated protein kinases (MAPKs). This effect can be attributed to a decrease in the levels of reactive oxygen species (ROS) and increased heme oxygenase-1 (HO-1) expression. Moreover, whole-genome sequencing revealed that L. plantarum Z22 contains gene-encoding proteins with anti-inflammatory functions, such as beta-glucosidase (BGL) and pyruvate kinase (PK), as well as antioxidant functions, including thioredoxin reductase (TrxR), tyrosine-protein phosphatase, and ATP-dependent intracellular proteases ClpP. In summary, these results indicated that L. plantarum Z22 can serve as a potential candidate probiotic for use in fermented foods such as yogurt (starter cultures), providing a promising strategy for the development of functional foods to prevent chronic diseases.

On‐Purpose Production of Light Olefins Through Oxidative Dehydrogenation: An Overview of Recent Developments

AbstractProducts made from light olefins play an important role in our daily lives. Traditional light olefins production based on steam cracking and fluid catalytic cracking suffer from high energy consumption and CO2 emissions. Thereby, the continually increasing demand for light olefins needs to be met through more environmentally sustainable procedures. On‐purpose production routes are preferred choice among petrochemicals manufacturers, being energy efficient and having lower carbon footprint. Among them, oxidative dehydrogenation (ODH) of light paraffins is a thermodynamically favourable exothermic process as compared to non‐oxidative routes. They can be operated at lower temperatures and have propensity of low coke deposition on catalyst, thereby resisting rapid catalyst deactivation. Herein, we have analysed various catalytic systems utilised in the oxidative dehydrogenation process. We have reviewed role of support, chemical composition of catalyst, presence of dopant, oxidation state of active metal, controlled surface modification by oxidative and reductive pretreatments, and reaction factors for each system. The performance of various catalytic systems for ODH of ethane, propane and butane in the presence of O2, CO2, N2O and special oxidants have been reviewed. A short critical overview on emerging on‐purpose routes for the production of renewable 1,3 butadiene has also been discussed.

It evaluates various hydrogen production techniques, including steam methane reforming, electrolysis, and biomass gasification, and discusses how CCS can enhance environmental sustainability. Key challenges, such as economic, technical, and regulatory obstacles, are analyzed. Case studies and future trends offer insights into the feasibility of CCS–hydrogen integration, providing pathways for reducing greenhouse gases and facilitating a clean energy transition.

Supplanted by electron-deficient B to form RuN2B-CoN4 moiety as superior catalytic site to further promote urea production

The potential significance of electrocatalytic urea synthesis as a promising alternative to traditional manufacture is widely recognized. However, the critical hindrance is lack of its highly efficient and robust electrocatalysts until now. Alongside the exploration of novel urea catalysts, it is equally crucial to explore feasible strategies to boost the performance of the identified active sites. In this work, we proposed and demonstrated a modulatory scheme to further promote urea production in Ru-Co dual-metal sites through the substitution of electron-deficient B atom in RuN3 subunit to form RuN2B-CoN4 moiety in graphene. The B-coordinated Ru active site can effectively decrease charge transfer amount from the Ru atom to the substrate. The enhanced single-atomic similarity to free Ru atom results in more negative adsorption energy for N2 molecule and superior catalytic activity/selectivity for urea generation. More significantly, this study provides a new perspective to promote the catalytic performance of the carbon-based diatomic active sites for urea production.

Recent Advances in Additive Friction Stir Deposition: A Critical Review

Additive friction stir deposition (AFSD) is a novel solid-state additive manufacturing method developed on the principle of stirring friction. Benefits from its solid-phase properties, compared with traditional additive manufacturing based on melting–solidification cycles, AFSD solves the problems of porosity, cracks, and residual stress caused by the melting–solidification process, and has a significant improvement in efficiency. In AFSD, the interaction between feedstocks and high-speed rotating print heads suffers severe plastic deformation at high temperatures below the melting point, ending up in fine, equiaxed recrystallized grains. The above characteristics make components by AFSD show similar mechanical behaviors to the forged ones. This article reviews the development of AFSD technology, elaborates on the basic principles, compares the macroscopic formability and material flow behavior of AFSD processes using different types of feedstocks, summarizes the microstructure and mechanical properties obtained from the AFSD of alloys with different compositions, and finally provides an outlook on the development trends, opportunities, and challenges to the researchers and industrial fields concerning AFSD.

Impact of Various Smoking Techniques on Polycyclic Aromatic Hydrocarbon (PAH) Formation in Dry-Cured Pork Neck (Buđola)

Traditional meat products that are smoked may pose health risks due to polycyclic aromatic hydrocarbons (PAHs). Recently, concerns have grown about the health implications of meat products smoked under traditional, uncontrolled conditions. This study compares the levels of polycyclic aromatic hydrocarbons in specimens of the dry-cured meat product “Buđola” made in traditional smokehouses versus industrial chambers. PAHs were measured upon completion of smoking and when the production was complete. The findings indicate that traditional smoking methods lead to higher PAH contamination compared to industrial methods. Among the 16 PAHs analyzed, 10 (NA, AL, FL, ANT, PHE, FLT, BA, PR, BBF, BKF) were detected in traditionally smoked “Buđola” samples, whereas only 2 (NA, AL) were found in samples smoked by industrial methods. The BP levels in all samples were undetectable. PAH4 levels in industrial smoked “Buđola” were below the quantification limit, while those in traditional products were 28.77 μgkg−1 for the surface layers and 21.14 μgkg−1 for inner layers. The total PAH16 content ranged from 4.32 μgkg−1 to 3587.83 μgkg−1. The inner layers had lower concentrations of overall and specific PAHs in relation to the product surface. The results suggest that, from a health perspective, industrially produced “Buđola” is safer for consumption than the product smoked in uncontrolled conditions.

Composite Recycling with Biocatalytic Thermoset Reforming.

Carbon fiber reinforced polymers (CFRPs, or composites) are increasingly replacing traditional manufacturing materials used in the automobile, aerospace, and energy sectors. With this shift, it is vital to develop end-of-life processes for CFRPs that retain the value of both the carbon fibers and the polymer matrix. Here we demonstrate a strategy to upcycle pre- and postconsumer polystyrene-containing CFRPs, cross-linked with unsaturated polyesters or vinyl esters, to benzoic acid. The thermoset matrix is upgraded via biocatalysis utilizing an engineered strain of the filamentous fungus Aspergillus nidulans, which gives access to valuable secondary metabolites in high yields, exemplified here by (2Z,4Z,6E)-octa-2,4,6-trienoic acid. Reactions are engineered to preserve the carbon fibers with much of their sizing so that the isolated carbon fiber plies are manufactured into new composite coupons that exhibit mechanical properties comparable to those of virgin manufacturing substrates. In sum, this represents the first system to reclaim a high value from both the fiber fabric and polymer matrix of a CFRP.

“We always remember for whom we make a tandyr”. Ethnoarchaeological research on tandyrs in southern Kyrgyzstan

The article has two informative levels: (a) describes the construction, distribution and use of tandyr cores as a traditional product of the bread-baking culture in southern Kyrgyzstan; compares these processes with the well-documented phenomenon of tandyrs in the Middle East and (b) tries to define the implications for potential archaeological research of tandyrs in this area, where (despite their claimed general distribution and use) these products have not been archaeologically identified to date. The basic method of the work is the direct collection of ethnographic data at four production locations and dozens of consumption locations through direct observation and formalized questionnaires.

Metal-Based Oxygen Reduction Electrocatalysts for Efficient Hydrogen Peroxide Production.

Hydrogen peroxide (H2O2) is a high-value chemical widely used in electronics, textiles, paper bleaching, medical disinfection, and wastewater treatment. Traditional production methods, such as the anthraquinone oxidation process and direct synthesis, require high energy consumption, and involve risks from toxic substances and explosions. Researchers are now exploring photochemical, electrochemical, and photoelectrochemical synthesis methods to reduce energy use and pollution. This review focuses on the 2-electron oxygen reduction reaction (2e- ORR) for the electrochemical synthesis of H2O2, and discusses how catalyst active sites influence O2 adsorption. Strategies to enhance H2O2 selectivity by regulating these sites are presented. Catalysts require strong O2 adsorption to initiate reactions and weak *OOH adsorption to promote H2O2 formation. The review also covers advances in single-atom catalysts (SACs), multi-metal-based catalysts, and highlights non-noble metal oxides, especially perovskite oxides, for their versatile structures and potential in 2e- ORR. The potential of localized surface plasmon resonance (LSPR) effects to enhance catalyst performance is also discussed. In conclusion, emphasis is placed on optimizing catalyst structures through theoretical and experimental methods to achieve efficient and selective H2O2 production, aiming for sustainable and commercial applications.

AI and work in the creative industries: digital continuity or discontinuity?

There is current uncertainty about the effects of generative AI technologies on labour markets and conditions of work in creative industries. Previous scholarship identifies the potential for both replacement and displacement of human labour due to AI adoption. This article examines potential effects of AI adoption by drawing on case studies of 6 commercial products using AI, investigating conditions of work and mechanisms by which human creative labour might be replaced or displaced by AI technology. The main findings are that AI products were more labour intensive than traditional media products because they combined traditional production skills and new computational expertise. Paradoxically, contributions by human workers tended to be invisibilised in final products that foregrounded AI technology. There was potential for displacement of human labour in the ideation phase, with AI enabling producers to explore different creative possibilities. Some AI products had the potential to compete with earlier production methods (e.g. AI-generated imagery vs. stock photography). Overall, case study findings were consistent with ongoing challenges from digitalisation: conditions of deskilling, re-skilling, flexible employment and uncertainty remain intense for small firms engaged in AI-assisted creative production.
