The paper discusses how artificial intelligence (AI) is transforming public services that are provided to people by governments and directing decision-making in the government. The research addresses the topic of AI technologies being fitted into government processes more often to achieve efficiency, better service provision, and data-driven policymaking. The research applies a secondary research methodology, which is a desk analysis of the available literature, in assessing the opportunities and challenges linked to the use of AI in the public sector. The results show that AI can enhance the quality of government and society services in the field of governance management, law enforcement, and medical services, and help make more informed administrative decisions. The paper also points to the significance of tackling the problem concerning data privacy concerns, ethical governance, and institutional preparedness. The study indicates that the successful implementation of AI should entail proper technological infrastructure, regulatory framework, and organizational capacity in government institutions.

Polymer–cement waterproof coatings couple the rigidity of cement and the elasticity of polymers into compositmembranes that prevent water penetration. In the system, polymer particles aggregate to form films in the cementitious matrix and hence plug up capillary pores and bridge micro- cracks].In this paper we present in depth case study of Dunlop K205—an acrylic polymer–cement coating for the Chinese market—and position the practical experience on the broader context of review of recent literature and commercial products. K205 was used to seal a high‑moisture bathroom in Santa Clara, USA. After six months, the coating was waterproof, flexible and did not delaminate even at elevated relative humidity.Compressive strengths and water absorptions are demonstrated in numerical results; polymer content is used to explain their variations in simulation. Comparison tables are provided among K205 and other products like Sika Damp Proofing Slurry, Drizoro Maxseal Flex and SinoMaco crystalline coatings. Permeability reduction formulas and bond strength formulas are derived for polymer contents. Real observations and simulation results for both of them are visualized by figures.We refer to $35$ articles — mostly which are published post-2020, according Vancouver style, wherein findings are reported and emphasized the benefits of polymer– cement waterproof coatings for residents as well as proper mixing, application and concerns related to sustainability issues.

The plastisphere is a newly recognized geospheric layer at a planetary scale, characterized by the presence of microorganisms, primarily as biofilms, that colonize inert and poorly decomposable organic matter, particularly plastics. The stability and diversity of substrate plastic fosters a consistent evolutionary trend among microorganisms, leading to specialized ecological niches that enhance particular physiological traits for plastic degradation. Biofilms have been observed on various types of plastics, including both conventional petroleum-based polymers (like polyethylene and polystyrene) and bioplastics (such as polyhydroxyalkanoates). The characterization of plastisphere objects is crucial and should be conducted with geodetic referencing and spatio-temporal metrics to understand the impacts of climatic and meteorological factors. The dynamic nature of species succession in response to environmental changes necessitates advanced analyzes of microbial communities’ potential for plastic degradation. The spatial turnover of core and occasional taxa complicates the precise identification of microbial functions within these communities. The question of “What is in the plastisphere?” emphasizes the need for detailed biogeographical and chemical mapping due to the small size and localized nature of microplastic particles. It is important to differentiate when plastics serve as growth resources (biodegrading) versus mere substrates for microbial growth, raising the question of “Food or just a free ride?” The geochemical and aerochemical activities within the plastisphere are crucial for understanding its broader environmental impacts. These activities include nitrogen metabolism and the biogeochemical cycling of nitrogen, phosphorus, and carbon, which encompasses greenhouse gas emissions associated with plastic degradation. Additionally, trace metals can accumulate in the plastisphere, potentially facilitating photo-Fenton processes that may occur on microplastic surfaces when exposed to sunlight.

Forensic science fundamentally centers on detecting and interpreting clues, many of which are extremely small, easily degraded by environmental conditions, or intentionally concealed. Traditional forensic methods remain reliable and legally accepted; however, they increasingly struggle to address emerging forms of highly minute and complex evidence. In response, researchers are turning to nanotechnology to enhance forensic capabilities. Working at the nanoscale offers improved sensitivity, selectivity, and accuracy, enabling forensic scientists to detect, visualize, and analyze trace evidence with greater precision. This review examines the expanding role of nanotechnology across diverse forensic domains, including fingerprint visualization, gunshot residue detection, DNA analysis, document authentication, drug-related investigations, and postmortem interval estimation. Rather than suggesting that nanotechnology will replace established approaches, this article compares nanoscale methods with conventional techniques, highlighting their respective advantages, limitations, and practical considerations. Key challenges, such as validation, reproducibility, interpretation of results, and admissibility in court, are critically discussed. By assessing how nanotechnology can both support and complicate forensic workflows, this review provides a balanced perspective on its realistic contributions and shortcomings. Through integrating recent scientific advances with an understanding of forensic constraints, the article aims to clarify how nanoscale technologies may meaningfully strengthen forensic science while upholding the evidentiary standards demanded by the justice system.
