Production planning based on factory gathered information or known variables paired with prognosis techniques for photovoltaic energy generation results in an energy optimized industrial cycle. All elements involved in this kinematic chain, such as the state of equipment, human-made decisions and interactions, and active power generation will result in a specific energy efficiency point, which in most cases can be improved by proper production planning. By implementing tracking of energy consumption cycles and forecasting renewable energy production, manufacturing process can be defined so that most power intensive actions consume predominantly low-cost clean energy. Thus, leading to faster scheduling based on accurate production parameters such as required volumes, maintenance schedules, down-times, and other types of factors which impact the devised tasks. This paper introduces a software implementation that incorporates a cumulus of factors to enable repeatability in the decision-making process. The paper's focus is to present the logical structure of this implementation, demonstrated through an example involving a plastic injection molding facility operating primarily in the automotive sector.","PeriodicalId":18107,"journal":{"name":"Macromolecular Symposia","volume":"414 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/masy.70064","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144309168","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this context, metakaolin-based geopolymers, or amorphous aluminosilicate polymers, have been synthesized in the presence of 20 wt.% of extraction sludges from food supplement production (W1) and from partially stabilized industrial waste (W2), used as filler after metakaolin activation with alkaline solution. A comparison study in terms of physicochemical properties has been conducted between the geopolymer control (GP0) and those with the two fillers (i.e., GPW1 and GPW2). Fourier-transform infrared spectroscopy (FT-IR) was used to follow geo-polymerization occurrence, while integrity test and compressive strength were used to understand the differences between the synthesized samples. Eventually, the leaching test and antimicrobial activity were also carried out. The main findings revealed that the wastes do not influence the geo-polymerization and the GPW1 and GPW2 had a stable macroscopic structure. The presence of alumina in W2 led to a gas formation with a hardened highly porous structure and a decreased compressive strength. GPW1 showed a higher compressive strength than GP0. None of the geopolymers released heavy metals suggesting that the matrices were able to inertize the wastes. Finally, both wastes and geopolymers revealed antimicrobial properties.","PeriodicalId":18107,"journal":{"name":"Macromolecular Symposia","volume":"414 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/masy.70025","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144309170","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Petrol-derived polymers, such as low-density polyethylene, can be replaced by biodegradable (bio)polymers in mulching activities, which, after crop harvest, do not need to be removed, but they are very often buried in the soil, thus allowing the farmers to economize on their disposal. A kind of biodegradable mulching film is constituted of a polylactic acid/poly(butylene adipate-co-terephtalate) blend, which is known to be subjected to both enzymatic and photooxidative degradation under aerobic conditions. However, during degradation processes, the mulching films can give rise to microplastic debris, which, in turn, could act as micro-vectors of organic and inorganic pollutants. Understanding the adsorption capability of agricultural mulching films toward active substances commonly used in agricultural activities to enhance crop harvesting could help farmers in choosing the appropriate plastic while trying to reduce environmental pollution. In this study, the adsorption behavior of a commercial polylactic acid/poly(butylene adipate-co-terephtalate) film is investigated, considering azoxystrobin, a widely used organic fungicide, as the active substance.","PeriodicalId":18107,"journal":{"name":"Macromolecular Symposia","volume":"414 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/masy.70033","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144309023","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study's methodology includes defining the basic need, based on which the authors identified the main function as primary, secondary and tertiary. These functions were organized into a hierarchical structure and weighted to determine their relative significance, followed by an evaluation from both technical and economic perspectives. Using the least squares method, the cost-effectiveness of these functions was analyzed and results the development of an optimal conceptual framework for the humanoid robot's design. Several functions were identified for further optimization in terms of lowering their costs in relation to the value they bring to the humanoid robot concept.

The aim was to demonstrate the relationship between the surface roughness of the analyzed samples and their porosity. The surface roughness is enhanced with enhanced porosity which creates irregularities and variations on the surface topography and morphology of the rough nanostructured hybrids in which the organic and inorganic phases are bonded together at nanometer to sub-micrometer scales. The results revealed an increase in material porosity as a function of the PEG amount. The nanoscale roughness of the matrix SiO2 is relatively low, as confirmed by the roughness parameters Ra = 2.29 nm and Rq = 4.18 nm. Instead, for all SiO2/PEG hybrids, roughness values greater than those shown by the SiO2 matrix alone, which appear to gradually increase as the weight percentage of PEG increases, were detected. The findings showed that the amount of PEG in the analyzed systems increased the material porosity, underscoring the crucial role that PEG amount plays in compatibilizing the morphological characteristics of blends based on silica. This study opens the door to the realization that improving the sol–gel SiO2/PEG materials' porosity and roughness surfaces can have a variety of effects for various applications.","PeriodicalId":18107,"journal":{"name":"Macromolecular Symposia","volume":"414 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/masy.70028","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144309076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through the sol–gel method, it is possible to tailor the size and control the porosity, as well as, to obtain pure hybrid materials. In this study, several inorganic–organic silica/PEG (polyethylene glycol) hybrids have been synthesized through the sol–gel method, by using tetraethylortosilicate (TEOS) as the SiO2 precursor. The PEG amount was 6, 12, 24, and 50 wt.% to SiO2 stoichiometrically calculated. The inorganic phase is well-known in literature as bioactive, while the organic phase improves mechanical performance. The influence of the organic phase has been investigated through the Fourier-transform infrared spectroscopy (FT-IR) in the range of 4000–400 cm−1. A deconvolution study of the main Si─O─Si stretching vibration in the range 1600–800 cm−1 has also been carried out. According to the observation of FT-IR spectra, the changes in the shape of O─H stretching and banding, as well as the presence of CH2 and CH3 vibrations in silica/PEG spectra revealed the co-presence of both phases. This finding is strengthened by the presence of C─O bending found in the deconvoluted spectra affecting the intensity and the shape of the Si─O─Si vibration band.","PeriodicalId":18107,"journal":{"name":"Macromolecular Symposia","volume":"414 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/masy.70023","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144309172","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
