The first two contaminants are the result of the increased human excretion and improper disposal [1,2]. Although the concentrations of these contaminants are very low, typically in the nanomolar range, acetaminophen’s long-term exposure to individuals can cause increased mortality, as well as heart, gastrointestinal, and kidney diseases, and estrogen is toxic and can cause breast and prostate cancers. Estrogen is a plasticizers' derivative chemical, resulting from leaching from packaging materials such as feeding bottles, water bottles, and beverage cans into food and water. Exposure to bisphenol-A can also adversely affect on brain, thyroid, and reproductive organs, leading to neurodegenerative, cardiovascular, and carcinogenic diseases due to its toxic behaviour [3,4]. Therefore, frequent monitoring of these contaminants is critical to predict their exposure and adverse effect to humans. Conventional analytical techniques such as liquid chromatography and enzymelinked immunosorbent assay are commonly used for detecting these contaminants [3]. However, recently, electrochemical sensing techniques have shown much promise for simple, rapid, and precise detection of these contaminants.

Previous research has identified windscreens as an effective measure to mitigate dust resuspension from stockpiles [1]. However, the efficiency of these measures is significantly influenced by factors such as wind conditions, pile and windscreen configuration, and stockpile arrangement [1]. Previous studies conducted using field and experimental methods have been resource-intensive and faced difficulties in establishing a controlled environment that without interfering with ongoing operations [2], and in scaling of the experiments [3]. To supplement these studies, the present work utilized Computational Fluid Dynamics (CFD) simulations to assess the impact of wind erosion on dust resuspension from stockpiles [4] [5][6]. CFD simulations were conducted using a numerical modeling approach to investigate the fluid flow over stockpiles and the resulting dust resuspension. The model was scaled at a ratio of 1:100 to represent two stockpile geometries for bulk materials: a conical pile and a flat oval top pile, both with a height of 11m and an angle of repose of 37˚, with a domain ar ea of 4m (L) x 1m (W) x 1m (H) [1][5]. The domain was discretized using the tetrahedral method, and the lateral walls were assigned symmetry boundary conditions. The bottom wall was set at a roughness of 4 mm with a no-slip condition.

Drying of clothes is a crucial part of laundry, and in most developing countries this means spreading clothes on lines to be dried by the sun, or passive outdoor drying (POD). However, due to urbanisation and the proliferation of condos there is little room for sun drying clothes. Additionally, electric washing machines and clothes dryers have become commonplace in many modern homes, however, they consume enormous amounts of energy when drying clothes. Moreover, most families in under-served countries often cannot afford exorbitant electricity bills making these methods to domestic laundry not sustainable. With the continued drive for sustainable living, there is a need for energy conservation alternatives. In other related research work solar energy has been applied in agriculture for drying and preserving food, in electricity and lighting using Photovoltaic (PV) cells, and for heating via radiation. This article explores an alternative for domestic laundry with solar energy, harnessed heat and related technologies. This work does not rely solely on PV cells to generate electrical energy to power heaters, rather we borrow from the food drying process used in agriculture. This entails combining solar concentrators, which focus the sun’s energy into a chamber, with a system that channels household heat sources into the same chamber. Within this chamber clothes are hung using smart clothes pegs, which hold the clothes in place. The pegs also measure the moisture level of each garment, then use the telemetry data to control the heat within the chamber. Using these combined systems, enormous amounts of grid electricity and carbon-dioxide emissions can be saved. Actor Network Theory (ANT) and relevant adoption models and theories will investigate consumer adoption and how this technological design is shaped by encompassing socio-cultural factors and physical realities.","PeriodicalId":398088,"journal":{"name":"Proceedings of the 9th World Congress on New Technologies","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123318790","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Inorganic nanoparticles (NPs), due to their unique physicochemical properties, have become attractive materials for various commercial and technological applications. Using metal NPs is most commonly associated with implementing their bactericidal and bacteriostatic properties. Unfortunately, the progressive production and use of nanoproducts with such amenities significantly increase the risk of their release into the environment, where they may threaten non-target microorganisms. Unfortunately, the lack of appropriate tools makes it impossible to distinguish NPs of anthropogenic origin from those naturally occurring in the environment and perform a full risk assessment. Therefore, extensive toxicological studies using both model microorganisms and environmental strains to evaluate the biological effects of NPs are of utmost importance. The mechanisms responsible for the biocidal activity of metallic NPs are still not fully understood due to their variety and non-specific mechanisms of action. However, the response of microorganisms to NPs is believed to be mediated by numerous cellular phenomena and processes. Firstly, NPs act on the bacterial cell’s outer layers, interacting with the surface structures and leading to changes in cell membrane integrity and permeability [1,2].

Despite existing studies identifying the pollutants and detecting their concentration within the lake, their sources were generally attributed to agricultural activities, considered a nonpoint source. This research modelled the diffuse sediment and nutrient pollution affecting Lake Palakpakin, San Pablo City, Laguna using Soil and Water Analysis Tool (SWAT). This model is physically based, requiring DEM, soil map, LULC map, slope map, and meteorological data as inputs to model physical processes associated with water movement, sediment movement, nutrient cycling, etc. Due to the unsatisfactory statistical results of the calibrated model caused by insufficient hydrological data, the uncalibrated simulation was used. It revealed that the critical source areas for NO 3 -N and PO 4 are found in agricultural lands and areas that are underlain by clay and clay loam. Critical source areas were also found along the stream connecting Palakpakin lake to Laguna de Bay. Meanwhile, higher sediment yields were distinct around Sampaloc Lake and the outlet of the other lakes and in agricultural and urban areas.

Molecular dynamics simulations based on the reactive force field ReaxFF were employed to investigate these interactions. Various solvent environments based on water and ethanol proportions were examined. The simulation results reveal that dye chemisorption always occurs, but with differences depending on the solvent used. A more favorable stability and Ti-O bond distance were observed in systems with solvent ratios of 1:1 and 1:3, suggesting improved dye loading under these conditions. Additionally, sensitized solar cells were prepared using the same solvents utilized in the simulation, and current-voltage and IPCE measurements were performed. It was found that cells prepared with the more stable solvent ratios exhibit higher photocurrent and efficiency. Overall, the results from the molecular simulation are in agreement with the experimental data, indicating its potential for predicting the optimal solvents to use in the preparation of natural dyes based on anthocyanins.","PeriodicalId":398088,"journal":{"name":"Proceedings of the 9th World Congress on New Technologies","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125545563","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, Fe-Mn oxide was synthesized through chemical precipitation in solutions with varying concentrations of FeCl 3 • 4H 2 O and MnO 2 • 4H 2 O for oxidative adsorption of As(III) in aqueous solution. The synthesized Fe-Mn oxide mineral possessed oxidation property rendered from manganese dioxide phases and adsorption capacity from the iron oxide phases. The Fe-Mn oxide was characterized for surface area, morphology, composition, and magnetic property and bench scale laboratory experiments were carried out to investigate potential utility of the mineral in treating As(III) under the mineral dose of 1 g/L and 1mg/L As(III). The results of kinetic experiments revealed the oxidation of As(III) occurred in very short period time (less than 30 min.), followed by adsorption to iron oxide phase, with its removal efficiency being the highest for the mineral synthesized under 1:0.25 Fe:Mn condition. The maximum adsorption capacity determined from isotherm experiments was found to be 200 mg/g. The removal of As(V) remained relatively constant in the pH 3-6 at around 60% removal but dramatically decreased when pH was raise to 10. The ionic strength in the range of 0.001-0.1 M NaNO 3 and the presence of competing anion (0.1-1 mM PO 43) had little effect on the As(III) removal.

To treat and remove the contaminant from the soil, different techniques have been implemented, both in laboratory, pilot and full-scale applications. One of the most promising approach for mercury removal is thermal desorption, a treatment technology that utilizes heat to increase the volatility of contaminants which are subsequently removed from the solid matrix and treated in an off-gas treatment system [3]. In this work we analysed and treated a soil from an industrial area with high levels of mercury contamination, mostly in the forms of elemental mercury (24-67%) and insoluble inorganic mercury (32-73%). To understand the most effective remediation strategy, a series of tests have been performed on a different number of soil samples. The soil was collected via core drilling up to a depth of 5 metres, and each 1 metre layer was characterized in terms of total mercury contamination, dry residue, humidity, sieve fraction (less than 2 cm and more than 2 mm), and a mercury speciation was performed. After a first characterization, the layer with the highest mercury contamination was identified and 10 kg of material was selected for the subsequent analysis.
