Development of High-Strength 96.5% Gold for Sustainable Jewelry Product Design

2026-06-22T23:40:57+07:00

This study aims to develop high-strength 96.5% pure gold with enhanced hardness and durability in order to expand its potential for contemporary jewelry product design, while maintaining its purity, color, and aesthetic qualities, in alignment with the concept of sustainable design. The experimental process involved the incorporation of alloying elements—germanium powder, titanium powder, and graphene powder—at 0.1 wt% into 96.5% gold through melting and subsequent fabrication into sheet samples. The materials were evaluated for mechanical properties, including Vickers hardness and tensile strength, as well as microstructural characterization and alloying element distribution using FESEM-EDS analysis, and optical properties through CIELAB color coordinate measurement. The results indicate that germanium provided the most significant improvement, increasing hardness by 11.43% and enhancing tensile strength compared to the control sample. FESEM-EDS analysis revealed that germanium was uniformly distributed throughout the material, contributing to improved mechanical properties, whereas graphene exhibited agglomeration, resulting in reduced hardness. Color analysis showed that the addition of alloying elements caused only minor color changes (DE* ranging from 1.96 to 3.11), with the samples retaining color characteristics close to standard 96.5% gold. In terms of sustainability, a prototype 96.5% gold ring was developed and its carbon footprint was assessed following Cradle-to-Gate life cycle assessment principles, showing low greenhouse gas emissions of 1.4789 kgCO2e. The findings highlight the role of material innovation in supporting the design of more diverse, complex, and functional contemporary jewelry products, while demonstrating the integration of material development with sustainable design principles, offering practical applications for product design and the jewelry industry in the future.

A comparison of the cost and construction time of small residential houses using 3D-printed concrete systems versus conventional construction methods in Thailand

2026-06-21T12:32:31+07:00

This study aims to assess the cost feasibility of applying 3D Concrete Printing (3DCP) to small residential buildings in Thailand. Two standard house designs published by the Department of Public Works and Town & Country Planning were selected as case studies: Disaster Relief House 1 with a usable area of 36 square meters and Economy House 2 with a usable area of 77 square meters. The estimated construction costs of conventional construction were based on the official indicative costs provided by the Department. The 3DCP cost estimation was developed based on the cost calculation framework for Construction 3D Printing, considering a load-bearing 3D printed wall system that can partially replace wall construction, plastering, selected columns and beams, and formwork, while foundations or piles, floors, roofs, building services, and finishing works remain necessary.

The results indicate that, for single-unit construction, the 3DCP system is more expensive than conventional construction. For the 36-square-meter house, 3DCP costs approximately 24.4–25.7% more than the conventional system, while for the 77-square-meter house, it costs approximately 10.2–10.8% more. This is mainly due to the fixed costs of 3DCP, including printer mobilization, installation, digital toolpath preparation, machine calibration, and quality control. However, when a repeated production scenario of 10 units was considered, the unit cost of 3DCP decreased significantly. The 36-square-meter house showed a cost nearly equivalent to conventional construction, while the 77-square-meter house became approximately 1.0% less expensive than the conventional system. The findings suggest that 3DCP is not yet cost-effective for a single small detached house but has potential for repeated-unit projects, such as disaster relief housing, affordable housing, and community housing. Further research should be conducted using detailed bills of quantities, actual material prices, and cost data from 3DCP service providers in Thailand.

Laws and Standards for Three-Dimensional Printed Concrete Buildings: Limitations and Guidelines for Application in Thailand

2026-06-25T09:13:43+07:00

Three-Dimensional Concrete Printing, or 3D Concrete Printing (3DCP), is a construction innovation with the potential to reduce construction time, decrease the use of formwork, reduce certain types of labor, and enhance architectural freedom in terms of form. However, the application of this technology in actual building construction remains subject to significant limitations in terms of law, design standards, structural systems, materials, safety, and quality control processes. This is particularly evident in Thailand, where there are currently no specific laws or standards that directly regulate buildings constructed using 3DCP systems.

This article aims to analyze the status of Thai building control laws in comparison with relevant international standards, namely ICC-ES AC509, UL 3401, ISO/ASTM 52939:2023, and the guidelines of ACI Committee 564. It also proposes a framework for applying existing laws in conjunction with specialized standards in order to support the safe and systematic implementation of 3DCP in Thailand.

The study found that 3DCP should not be considered merely as a “new construction method,” but should instead be regulated as a building production system that integrates materials, machinery, printing processes, digital models, reinforcement, testing, and quality certification. Therefore, Thailand should develop a performance-based regulatory approach in parallel with the adoption of international standards. This would create a regulatory space in which innovation can be implemented without compromising the structural stability and safety of building users

A Contextual and Cultural Psychological Analysis of the 2025 Color of the Year Mocha Mousse Application in the Contemporary Creative Industry

2026-06-27T09:51:35+07:00

This analytical research aims to investigate the application contexts and aesthetic implications of the Pantone Color of the Year 2025, Mocha Mousse (PANTONE 17-1230), within graphic design and creative industries. By focusing on artistic expressions, socio-cultural environments, and psychological mechanisms, this study acknowledges that color usage has long exerted psychological influence and served as a symbolic medium across various eras. Utilizing a content analysis methodology to examine academic literature and trend reports, the analytical findings reveal that the Mocha Mousse hue is deployed as a strategic tool across three primary contexts: corporate identity design to reflect understated luxury, digital media design to mitigate the rigidity of technology, and print marketing emphasizing sustainability communication. Furthermore, theoretical analysis indicates that this warm brown tone functions as a symbolic representation addressing the psychological state of contemporary consumers who experience digital fatigue and yearn for emotional stability. In conclusion, these findings demonstrate that the Color of the Year 2025 is not merely a transient fashion trend, but rather a visual language reflecting a contextual shift in utilizing color psychology to cultivate stability, warmth, trust, a connection with nature, and human-centric communication in the post-digital era.

Architectural Design Guidelines for Enhancing the Potential of Individuals with Autism, Individuals with Down Syndrome, and Their Families

2026-06-21T19:29:39+07:00

The number of individuals with Autism Spectrum Disorder and Down Syndrome has continued to increase, while support systems for education, potential development, and preparation for independent living remain limited. Furthermore, most built environments do not adequately respond to the specific needs of these users, affecting their learning, life skills development, and social participation. This research aims to study and synthesize architectural design guidelines for a potential development center for individuals with Autism Spectrum Disorder, individuals with Down Syndrome, and their families. The proposed center is intended to support learning, life skills development, vocational preparation, and social participation through an appropriate architectural environment.

The study was conducted through a review of relevant literature and research, analysis of domestic and international case studies, investigation of user behaviors and needs, and synthesis of architectural design criteria. The design approach was developed based on the concepts of Neurodiversity, Therapeutic

Architecture, Inclusive Design, Nature-Based Design, and the application of Artificial Intelligence (AI) to support learning environments and environmental adaptation according to individual user needs.

The findings led to the development of design guidelines comprising sensory zoning, transition spaces that facilitate adaptation between activities, therapeutic landscapes, and responsive environmental systems capable of accommodating diverse user requirements. These design strategies demonstrate the potential of architectural environments to enhance learning, personal development, independence, and social participation among individuals with Autism Spectrum Disorder, individuals with Down Syndrome, and their families. The study further proposes an architectural framework for the future development of potential development centers that comprehensively and sustainably address the specific needs of their users.
