The thrust to find new technology and materials has been greatly increasing due to environmental and technological challenges in the progressive world. Among new standard materials and advanced nano-materials that possess a huge potential and superior thermal, mechanical, optical, and magnetic properties, which have made them excellent and suitable components for mechanical engineering applications. The current review paper deals with recent enhancements and advances in the properties of nano-structured glasses and composites in terms of thermal and mechanical properties. A fabrication method of nano-structured glass has briefly been discussed and the phase change material (PCM) method outlined. The comprehensive review of thermal and optical properties confirms that nano-fabricated glasses show both direct and indirect running of band gaps depending on selective nano-structuring samples. The electrical and magnetic properties also show enhancement in electrical conductivity on nano-structured glasses compared to their standard counterparts. The realistic changes in thermal and mechanical properties of nano-structured glasses and composites are commonly attributed to many micro- and nano-structural distribution features like grain size, shape, pores, other flaws and defects, surface condition, impurity level, stress, duration of temperature effect on the selective samples. Literature reports that nano-structuring materials lead to enhanced phonon boundary scattering which reduces thermal conductivity and energy consumption.

An attempt has been made to develop hybrid composites from benzoxazine monomer (C‐ddm) hybridized with DGEBA epoxy resin (EP) and reinforced with varying weight percentages (20 wt%, 40 wt%, 60 wt%, 80 wt% and 100 wt%) of glycidoxypropyltrimethoxy‐ silane (GPTMS) functionalized granite dust (GD) obtained from industrial granite cutting and polishing process in order to utilize them for electrical insulation applications. The thermal stability of granite dust reinforced poly(EP‐co‐C‐ddm) composites was studied by TGA analysis. Among the composites samples studied, 100 wt% GD reinforced poly(EP‐co‐C‐ddm) composites possess better thermal stability than that of other neat matrices and composites. Among the composites prepared using varying weight percentages of functionalized GD reinforcement, it was observed that 80 wt% GD reinforced poly(EP‐co‐C‐ddm) composites possesses better hydrophobic character than that of other neat matrices and composites. The value of LOI calculated for neat matrix (poly[EP‐co‐C‐ddm]) and 20 wt%, 40 wt%, 60 wt%, 80 wt% and 100 wt% GD reinforced composites was found to be 22, 28, 34, 40, 43 and 45 respectively. The 80 wt% GD reinforced poly(EP‐co‐C‐ddm) composites possess the higher values of tensile strength and flexural strength of 47 MPa and 140 MPa, respectively than those of their samples. The values of electrical surface resistivity and electrical volume resistivity of all the neat matrices and GD reinforced polybenzoxazine composites were found to be in the order of 1012 and 1013 respectively. The values of dielectric strength obtained from break down voltage (BDV) for neat matrix [poly(EP‐co‐C‐ddm)] and 20 wt%, 40 wt%, 60 wt%, 80 wt% and 100 wt% of GD reinforced poly(EP‐co‐C‐ddm) composites are 15.0, 15.5, 16.5, 17.0, 17.0 and 17.0 kV/mm, respectively. Data obtained from thermal stability, hydrophobic behavior and dielectric studies it was inferred that the hybrid polymer composites developed in the present work can be conveniently used in the form insulators, sealants, adhesives and matrices where application demands at high‐performance industrial and engineering applications.

This study explores the transformative potential of Industrial Design innovations, skills, theories, principles and methodologies, in advancing the circular economy within the built environment, with emphasis on Nigeria. A narrative literature review methodology was adopted. Emphasising their roles in driving efficiency, sustainability, and adaptability, Industrial Design principles, innovations, skills, theories, and/or methodologies are examined in relation to their contributions to enhancing flexibility, reducing developmental or construction timelines, and promoting resource efficiency as well as environmental aesthetics and stewardship. The study’s outcomes show that Industrial Design plays key roles in the promotion of circular economy through material efficiency and optimisation, disassembly and reuse, resource recovery and recycling, user centric design and community engagement, persuasive designs in the built environment as well as in the conversion of wastes to usable materials, aesthetic components and equipment. As urbanisation advances and environmental degradation worsens in Nigeria, this study underscores the relevance and impact of Industrial Design (as a field of design practice) in fostering innovative solutions for the wellbeing of both the present and future generations. The research advocates for the integration of multidisciplinary design teams and a holistic approach to design, empowering professionals to create sustainable and thriving communities. It, among others, recommends that greater recognition be accorded the roles of Industrial Designers and other environment-related professions in advancing circular economy and sustainability in the built environment.
