Potential Applications

A number of materials have been used for Medical Additive Manufacturing (MAM), such as stem cells, biopolymers, metals, bio-ceramics, and bio-glass. Recent research includes potential applications in the replacement of human tissues, organs, and bones by using the bio-printing technology. MAM also has been applied to build up a dummy prototype to simulate a complicated operation process before surgery. Sustainable design of MAM has a need for the development of the system to be environmentally, economically, and socially sustainable for its life cycle. This paper surveys the scope of the sustainability of MAM in terms of these three categories. The methodology and tools for assessment of the sustainable development of MAM processes are discussed. This paper analyzes several examples of the application of additive manufacturing in medicine which have been published in recent journals. There are four critical areas of the design-centered system integration for sustainable development in this survey. The investigations for MAM processes including (1) the materials, (2) the precision of the advanced machine tools and tissues, (3) the mechanisms of the processes, and (4) the mechanical properties of the implanted components after MAM. The results can be used as a reference for the assessment of future sustainable Design-Centered Integration for MAM.

Abstract In this work, robust superhydrophobic cotton fabrics with UV shielding, self-cleaning, photocatalysis, and oil/water separation were successfully prepared based on micro/nano hierarchical ZnO/HNTs (halloysite nanotubes) hybrid particles and silicone elastomer polydimethylsiloxane (PDMS). ZnO/HNTs hybrid particles were prepared by in-situ growth of ZnO nanoparticles on the surface of halloysite nanotubes (HNTs). ZnO/HNTs hybrid particles and PDMS were used to successively coat cotton fabric by dip-coating approach. The coated cotton fabric displayed excellent superhydrophobicity with a water contact angle of 162.5 ± 1° and photocatalytic degradation of methylene blue solution under UV irradiation owing to the roughness and photocatalytic performance provided by micro/nano hierarchical ZnO/HNTs hybrid particles and low surface energy achieved by PDMS. The as-prepared fabric also displayed outstanding self-cleaning and antifouling properties. In addition, due to its both superhydrophobic and superoleophilic characteristics, the as-prepared cotton fabric can be used to separate several oil/water mixtures and showed good recoverability. The superhydrophobic cotton fabric also exhibited excellent UV shielding performance with a large UV protection factor of 1643.28 due to strong ultraviolet-absorption, light scattering and frequent light reflection of ZnO nanoparticles in ZnO/HNTs composites coated on cotton fabric. Importantly, the as-prepared fabric retained superhydrophobic performance after 2000 cycles rubbing, 90h UV illumination, and immersing in acidic and alkali solutions with different pH values ranging from 1 to 14 for 1 h. These characteristics make multifunctional cotton fabrics a satisfactory candidate in various promising fields.

The article emphasizes the fact that traditional socio-economic indicators do not reflect the challenges of sustainable development adequately, and this is particularly true for the widely-used GDP indicator. In this connection the elaboration of sustainable development indicators is needed, taking into account economic, social and environmental factors. For Russia, adaptation and use of concepts and basic principles of calculation methods for adjusted net savings index (World Bank) and human development index (UNDP) as integral indicators can be promising. The authors have developed the sustainable development index for Russia, which aggregates and allows taking into account balanced economic, social and environmental indicators.
