2024-03-07T13:40:09+00:00

With the relaxation of China’s birth policies and the dual independence gained by Chinese women in both mental and economic aspects, maternity wear, as an essential item for pregnant women, has an enormous design space and a growing consumer market, attracting increasing attention from all quarters [1]. However, due to the continuous changes in pregnant womens body shapes and the fact that most women need to continue working and socializing during the early and middle stages of pregnancy [2], maternity wear has a short wearing cycle and rapid turnover [3] leading to the current unsustainable consumption of maternity wear. This study aims to explore the impact of environmental awareness on the sustainable consumption behavior of maternity wear. Specifically, the study objective is to use Grounded Theory to analyze sustainability issues within maternity wear consumption and identify the factors and stages influencing sustainable consumption behavior through online searches for relevant reports and comments. We address 2 research questions. RQ1: How to improve the sustainability of maternity wear to reduce unsustainable consumption? RQ2: How does environmental awareness influence sustainable consumption behavior in maternity wear? This article, based on Grounded Theory, to ensure the timeliness of comments and reports, conducted sample data collection from 2019 to 2022. We conducted searches using keywords such as “sustainable maternity wear,” “ecofriendly maternity wear,” “sustainable fashion,” “maternity wear consumption,” and “postpartum clothing consumption.” We obtained a total of 1086 relevant articles and materials. After careful screening, we narrowed down our searches and organized 45 feasible textual materials for our study. Through online searches for relevant reports and comments regarding sustainable consumption of maternity wear, it identified consciousness-related influencing factors and three stages of sustainable maternity wear consumption behavior. Furthermore, it proposed reference recommendations for promoting sustainable consumption of maternity wear through management practices.

2024-03-07T13:40:10+00:00

Hydrogen peroxide (H2O2) is a widely used chemical as an eco-friendly oxidizing agent, with water being the only byproduct of oxidation in applications like bleaching pulp and paper, making electronic semiconductors, chemical and detergent synthesis, and wastewater treatment. The direct synthesis approach is preferred to provide the environmentally friendly production of H2O2 for market requirements. Bimetallic PdNi nanocatalysts were chosen for this study because of their catalytic activity and the structural characteristics of the material system. First, for the development of order-structured bimetallic PdNi nanocatalysts based on mesoporous carbon template after hydrogen-assisted heat treatment at 750∘C. The transformation of the disordered structure into ordered intermetallically structured PdNi alloys with higher alloying extents was confirmed by X-ray absorption spectroscopy (XAS) and high-resolution transition electron microscopy (HR-TEM). Then, to improve the oxygen oxidation reaction, two-electron pathway selectivity was used by TiO2-C as a support-ordered structure material to facilitate strong metal-support interactions. XAS and X-ray photoelectron spectra (XPS) techniques show more clear evidence of metal-support interactions with electron transfer from defects in the TiO2-C support to the ordered alloyed PdNi nanocatalysts, resulting in record productivity and selectivity of H2O2 production at ambient conditions. The results demonstrated in this study will enlighten a reliable design of new heterogeneous nanocatalysts with ordered structure. Electron transfer between hybrid support and active sites can clarify the catalytic behavior and prompt further research during the direct synthesis of hydrogen peroxide.

Sensory Attributes and Phytochemical Composition in Microgreens: Implications for Acceptability Among School Students in Selangor, Malaysia

2024-03-07T13:40:10+00:00

Abstract. Microgreens, the young seedlings of edible plants, have gained attention for their potential health benefits and culinary applications. This newly emerging functional food crop has the potential to sustainably diversify global food systems, facilitate urbanization and climate change responses, and advance human health. However, their reception among school students remains an understudied area, particularly in the Malaysian context. In this study, five microgreens species including ulam raja, red amaranth, red radish, daikon, and corn were evaluated for their sensory perception and acceptability among secondary school students in Selangor, and their phytochemical compositions. Among the evaluated species, corn exhibited the highest intensity of sweetness, ulam raja demonstrated a strong aroma and bitterness, while red radish was notable for its astringency and heat. Red amaranth had the highest intensity of grassy taste, and all five microgreens had a low score for sourness. Corn had the highest rating on acceptability of flavor and overall eating quality, signifying its favorable impression among students. Conversely, red radish and ulam raja received the lowest acceptability scores in both categories. The highest total phenolic and flavonoid content and antioxidant activity was exhibited in ulam raja. These findings suggest the potential to leverage corn’s favorable acceptability to introduce microgreens into student diets. In general, this study highlights the correlation between sensory attributes and phytochemical composition, both influencing the Malaysian students’ perceptions of microgreens. By understanding their preferences, educators, policymakers, and entrepreneurs can formulate effective strategies for healthier eating habits among the youth and develop successful commercialization strategies.

Manufacture of Eco-cleaner Based on Eco-enzyme Reinforced Catalyst as Reduction of Metals and Impurities on Roller and Blanked to Improve Offset Quality

2024-03-08T10:53:22+00:00

Offset printing machines play an important role in the printing process in the printing industry, so many industrial players make various efforts to maintain the quality of offset machine printouts. One of the efforts made is to keep the rollers and blankets on the offset machine clean from metal impurities that come from printing inks. To keep rollers and blankets clean, industry players usually use chemical fluids that can clean rollers and blankets on offset machines. However, the continuous use of chemical fluids can damage the rollers and blankets due to oxidation of these chemicals over time. This affects the printing results, such as the paper getting easily damaged, the blanket becoming sticky, the print being uneven, and the density becoming low. In addition, the cleaning chemicals used can cause environmental damage such as water pollution and soil pollution. This research synthesizes an eco-cleaner from an organic waste fermentation process reinforced with a catalyst that can be used as a substitute for the chemicals used today. This research aims to produce an eco-cleaner product that can reduce metal impurities on rollers and blankets to improve the printing quality of offset machines. The resulting product works effectively to remove metal impurities without damaging the rollers and blankets because the eco-cleaner is non-corrosive. The resulting products can be used by the public and the printing industry. The method used in this research is an experiment with the fermentation synthesis method. Furthermore, the eco-cleaner is tested for characterization for feasibility according to SNI standards. The tests carried out are the organic plating test, physical properties test, test and then analysis of the test results to see the feasibility of the eco-cleaner.

2024-03-08T10:57:10+00:00

A paperboard is a packaging material that has the disadvantage of being easily torn. One of the techniques used to overcome this is lamination. Two types of paperboard are often used as packaging materials, namely duplex and ivory. This research aimed to analyze the tear resistance comparison between duplex and ivory paperboard types. There are four types of samples in this research, namely duplex non-lamination, duplex lamination, ivory non-lamination, and ivory lamination. The variations of duplex and ivory grammation used include 350 gsm, 300 gsm, 270 gsm, 250 gsm, 230 gsm, and 210 gsm. Measurement of tear resistance refers to SNI 1974:2012 using the Elmendorf method. Each sample was measured for the CD and MD directions. The results showed that for the same grammage, the tear resistance of ivory was greater than that of duplex. The highest increase in tear resistance occurred in duplex and ivory with grammatical 210 gsm. The percentage increase in tear resistance of duplex and ivory with grams of 210 gsm, 230 gsm, 250 gsm is more than 20%, while for higher grams the percentage is less than 15%.

Study of PG-Added Fountain Solution for Printing Offset Technique

2024-03-08T10:24:41+00:00

Although the printing technology, especially offset printing, has changed and grown quickly based on advanced invention and production capacity. However, the old offset machine printing such as one or two colour offset machines are still used massively in development countries. It is unpredictable when the old printing technology eliminated completely from the community, since it is affected by the economic level and extraordinary need of the public such as public election. The old machine which has been produced for more than 10 years usually has an issue related to the ink-water balance (iwb). The use of propylene glycol (PG) as single wetting agent improved iwb based on our previous study. Therefore, the effect of PG with fountain solution to the print quality is studied here. A series of fountain solution (FS) with additional content of 0 ppm, 13 ppm, 20 ppm, 40 ppm of PG was used to print an image on the art paper surface using sakurai offset machine. The optical parameters such as optical density (OD) and L*a*b were used to observe the effect of PG content in FS to the quality of printing. The OD on 0 ppm (reference), 13 ppm, 20 ppm and, 40 ppm of PG were 1.76 (reference), 1.83, 1.76, and 1.74, respectively. The optical density was identified as the maximum value at 1.83 on raster 100% of black colour for PG 13 ppm. At 13 ppm PG-added FS, the ΔE values of black (K) and Magenta (M) were 5.2 and 9.8, respectively, while ΔE values of cyan (C) and yellow (Y) were 1.7 and 1.8, respectively. It meant at PG 13 ppm, the K and M were stronger than the reference, while C and Y were equal. The same and lower OD compared to the reference showed unimproved color.

Structural Stability Study of Nanocluster PD-based Catalyst

2024-03-08T10:58:43+00:00

The rapidly growing population in the world demands an increase in the support of human life by providing massive production of food and medicine. As a result, the catalyst used in the production of the material plays a key role leading to intensive research. Synthesis of nanomaterials is becoming an important way to discover new catalysts by changing sizes and combining two or more metals on the nanoscale. Pd-based catalysts are well-known catalysts such as Pd-Pt, Pd-H, and Pd-Au for many chemical reactions such as the direct synthesis of hydrogen peroxide. Therefore, the provision of nanocluster bimetallic catalysts offers more benefits such as the rearrangement of surfaces to suit characteristics and lower material costs. However, the stability of the catalyst challenges researchers beyond reactivity and selectivity. In this paper, we predict the structural stability of Pd-based catalysts using a density functional theory approach. We use the 38-atom model in the M6@Pd32 core shell, where M is Hg, Pt, Au, Cu, Ni, Cu, Zn, Ag, Pd, and Cd, Pt. We prepared and investigated a series of structures such as truncated octahedral (TO) and polyhedral (PH) by calculating the excess energy. Based on our calculations and placing the monometallic Pd38 nanocluster as a reference, the TO structure is more stable than that of PH. The Zn6@Pd32 system showed the most stable followed by Cd6@Pd32 and Hg6@Pd32 was the worst.

Public--Private Cooperation Funding Juxtaposed of University--Community Engagement in Europe: Systematic Review

2024-03-08T14:38:05+00:00

This article explores the utilization of public–private funding models in European universities and its implications for community empowerment initiatives, particularly University–Community Engagement (UCE) projects. A systematic literature review (SLR) was conducted using the Scopus database, screening 50 articles relating to public–private funding models in European universities. The study reveals that while public–private funding models have gained traction in the academic sphere, they primarily focus on supporting applied science research projects. In contrast, the funding of projects solely oriented toward community empowerment remains limited, with only one article addressing this potential. The findings highlight the challenges associated with employing public–private funding for UCE projects with a strong emphasis on community empowerment. Public–private funding, typically sourced from industry partners, tends to prioritize product innovations and productivity enhancements, posing a mismatch with the social justice-oriented nature of UCE. This discrepancy underscores a significant research gap in UCE and calls for innovative approaches to develop supportive funding frameworks that can effectively sustain UCE initiatives.

It is interesting to see the relationship between Stan and Amy and their different characteristics from which arise the conflicts in facing life in order to create the intact theme. By looking at Stan’s first appearance in the novel, it seems White has a preconceived role or set of characteristics he wants to apply to Stan’s character. His bitter experience makes him become well-known as a “pretty stubborn man” by the people around him. In the meantime, Amy’s characteristics have also been prepared by White through the function of three things which were given to her by the Parson’s wife at the wedding party. Those three things are: a bible, a blouse as good as new, and a little silver nutmeg grater. Of course, they are given to Amy, but there is an impression that both Stan and Amy will have to adopt those kinds of characteristics in life. For further analysis, let us see the appearance of the protagonists as symbolized by the three things in expressing the theme.
