Sesuvium portulacastrum was shown to absorb sodium (Na+) and clor (Cl-) from the soil and accumulate it within its tissues. Therefore, it was chosen as a good plant for the phytodesalination of saline soils. The present study aimed to evaluate plant capacity to accumulate cloride ions and the potential to desalinize in saline soil medium of this halophyte. The results show that S. portulacastrum has a high tolerance at salt concentrations from 0.5% - 5% in growth terms of stem height, number of branches level 1, root length, and fresh biomass. Plants absorb a marked Cl- ions content clorideine and accumulate in roots, stems, and leaves. The efficiency of salt removal is 92% in the treatment of NaCl 1%. These results contribute to reducing soil salinity, so it is possible to apply sea buckthorn to treat saline soil environments.

Improving and exploring the photocatalytic performance of composites for new models continues to pose a challenge. Here, a straightforward thermal dispersion method is achieved by incorporating nitrogen (N) into TiO2 at different weights (1%, 3%, and 5%) to enhance photocatalytic activity. The material properties are analyzed through ultraviolet-visible diffuse reflectance spectroscopy (UV-VIS DRS), and X-ray diffraction (XRD). The results indicate that the NO gas removal efficiency of N-TiO2 photocatalytic materials is higher than that of pure TiO2 after 30 minutes of exposure to visible light. The highest NO gas treatment efficiency of N-TiO2 -1% is 40.4%, with a reaction rate following a first-order kinetic equation of 0.0688 min-1. Successfully fabricating N-TiO2 photocatalytic materials using the thermal dispersion method, with significantly enhanced photocatalytic performance under visible light activation, will benefit practical applications, particularly in the environmental sector.

Abstract The 2023 air quality assessment was conducted at five key industrial sites (Song Than II Industrial Zone, Thuan Giao Industrial Cluster, Thuong Tan Quarry, My Phuoc II Industrial Zone, Bau Bang Industrial Zone) in Binh Duong province, aiming to evaluate the potential air pollution in surrounding areas and the health impacts on workers in nearby residential areas. The survey results for several air pollution parameters, including NO2, total suspended particulates (TSP), and noise levels from the 2023 monitoring data provided by the Center for Environmental Monitoring and Technical Resources in Binh Duong province, indicated that at the Thuong Tan Quarry, TSP concentrations ranged from 26.0 to 374.8µg/Nm3, exceeding the standard by 74.8µg/Nm3 according to QCVN 05:2023/BTNMT. Noise levels at the quarry ranged from 59.7 to 72.1 dB(A), exceeding the standard by 2.1 dB(A) according to QCVN 26:2010/BTNMT. Additionally, air quality monitoring results at various industrial sites in Binh Duong indicated that the annual average levels of air pollutants at these industrial zones met the permissible limits set by QCVN 05:2023/BTNMT and QCVN 26:2010/BTNMT, with TPS concentrations ranging from 11.5 to 374.8µg/Nm3, noise levels from 57 to 72.1 dB(A), and NO2 concentrations from 18 to 85.5µg/Nm3. According to the 2023 air quality results, air quality in industrial zones has relatively improved compared to previous years, although some monitoring points still exceed the regulatory limits. Due to the different nature of production activities at the quarry compared to other industrial sites, more dust and noise are generated, necessitating management measures for production equipment and technological changes.

In this paper, the structural properties of crystalline and polycrystalline Cr have been investigated using molecular dynamics simulations. The interaction between atoms is modeled via the MEAM potential. Periodic boundary conditions are applied in the x, y, and z directions. The structural characteristics are analyzed through the total energy function, heat capacity, radial distribution function, and angle distribution. Dynamics are evaluated through the analysis of mean squared displacement and diffusion coefficient. The results show that the melting temperature of crystalline Cr is higher than that of polycrystalline Cr, indicating that the polycrystal melts earlier. This information is important when considering material applications in high-temperature environments.

ABSTRACT Nowadays, parents' needs are increasing to choose toys, especially painting colors, that are both beautiful, ensure their children's health, and are also environmentally friendly. In the production of industrial painting colors, waste from steps in the watercolor production line, if not treated to meet environmental standards according to regulations, will become a huge hazard to the environment and human health. human. Including causing skin, eye, digestive, and respiratory allergies. Causes poisoning, disease, cancer... Destroys the aquatic environment, trees, pollutes rivers and lakes. When building an industrial painting colors production line and putting it into use, if you do not think about solutions to treat wastewater from the production process, it will not be able to operate long term. Wastewater from color factories is mainly heavy metals contained in painting colors such as lead carbonate, oxide, and metal salts containing cadmium chromate. These substances cause mass death of organisms in the water, and polluted water cannot be used for agriculture. This research uses two main methods: experimental research to create products; combined with the questionnaire survey method to get customer opinions after using the painting colors test. Research results show that painting colors products made from fruits and vegetables combined with beeswax and coconut oil are very eye-catching and receive positive feedback from customers. With the im of protecting children in the future and responding to the green environmental message in the world, we hope that safe painting colors products from vegetables and fruits will be popularized in the community in the future. Keywords: vegetables, painting colors, environmental protection, safe products, beeswax.

Diatomite from Tuy An district, Phu Yen province, with different purities and diatom integrity as catalyst carriers, were adopted to prepare TNTs/g-C3N4 composite catalysts by a sol-gel method, with an optimal weight ratio of 1:1 for TNTs/g-C3N4 and diatomite. Compared with pure TNTs, g-C3N4, and TNTs/g-C3N4, the obtained composite photocatalysts exhibited lower photocatalytic performance under the same conditions and NO removal within 30 min under visible light. The NO gas treatment efficiency under the same conditions with different catalyst supports only decreases by approximately 18% at a reaction rate of 0.0950 min-1. This research on composite photocatalysts is a promising step towards practical environmental remediation. The use of diatomite as a carrier for photocatalytic materials is particularly noteworthy, as it is a naturally available and cost-effective source of materials. However, further improvements in the photocatalytic performance of the composite material are necessary to fully realize its potential in environmental remediation, including removing NOx and other pollutants. Overall, this study provides valuable insights into the influence of carriers on the photocatalytic activity of composite photocatalysts and lays the foundation for future research in this field.

Abstract: Urban agriculture is a highly concerned issue during the period of rapid urbanization in Vietnam. Research aims to propose a cultivation process for cultivating oyster mushrooms, utilizing coffee grounds from coffee businesses as a resource. This approach promotes circular economy principles, generating economic benefits for households while protecting the environment and being suitable for urban areas. The study conducted experiments on grey oyster mushrooms using different mixtures of coffee grounds and rubber wood sawdust at the following ratios: 0%, 25%, 50%, 75%, and 100% coffee grounds/rubber wood sawdust, filled into bags with a weight of 1.2kg. The research results showed that disease infection rates were mild in the 0% and 25% mixture ratios, while the remaining ratios exhibited moderate to severe infection levels. The highest mushroom yield was observed in the mixture ratio of 25% coffee grounds, with an average number of mushroom ears per bag reaching 29.7grams/bag, the dry weight is 63.8 grams/bag, with an average size ranging from 3 to 14 cm and a moisture content of 79.5%. The fastest colonization speed on the substrate is achieved by 25%, 50% coffee grounds blend, which fully colonizes the bag in a period of 25 to 35 days, the shortest time compared to the 75% and 100% coffee grounds blends, which take 40 to 45 days. The experimental results show that the 25% coffee grounds: 75% rubber sawdust blend is suitable for urban mushroom cultivation models and can be expanded on a large-scale farm, contributing to minimizing environmental pollution, utilizing limited urban land area, and providing high economic efficiency.

S-TiO2 typically exhibits high photocatalytic activity, but its powdered form makes it difficult to apply practically in environmental treatment. Diatomite from different locations varies in purity and integrity of the diatomaceous earth, making it a suitable catalyst support for synthesizing mixed-phase S-TiO2 catalysts using the sol-gel technique. The synthesized photocatalyst exhibits similar photocatalytic activity to S-TiO2. The NO gas treatment efficiency under the same conditions with different catalyst supports only decreases by approximately 3% within 30 minutes at a reaction rate of 0.0950 min-1, with an optimal mass ratio of 70:30 for S-TiO2 and diatomite. This composite material holds promise for addressing the application of photocatalytic materials in practical environmental treatment, including NO removal and the treatment of other environmental pollutants, as diatomite is a naturally available and environmentally friendly material.
