The building physical properties of Leca design wall structure are studied along with the environmental impact and load-bearing capacity. To compare the results, a similar analysis is carried out considering the traditional wooden wall construction of passive houses. The results showed that Leca design wall structure can be an alternative sustainable solution to the traditional wooden wall structure of passive house, mainly due to its low U-value, its ability to handle moisture, and comparable structural load-bearing capacity. However, the wooden wall structure is more environmentally friendly than the Leca blocks due to its lower emissions to the environment and reduced energy use, especially during the manufacturing process.展开更多

摘要Leveraging the biocatalytic machinery of living organisms for fabricating functional bioelectronic interfaces,in vivo,defines a new class of micro-biohybrids enabling the seamless integration of technology with living biological systems.Previously,we have demonstrated the in vivo polymerization of conjugated oligomers forming conductors within the structures of plants.Here,we expand this concept by reporting that Hydra,an invertebrate animal,polymerizes the conjugated oligomer ETE-S both within cells that expresses peroxidase activity and within the adhesive material that is secreted to promote underwater surface adhesion.The resulting conjugated polymer forms electronically conducting and electrochemically activeμm-sized domains,which are inter-connected resulting in percolative conduction pathways extending beyond 100μm,that are fully integrated within the Hydra tissue and the secreted mucus.Furthermore,the introduction and in vivo polymerization of ETE-S can be used as a biochemical marker to follow the dynamics of Hydra budding(reproduction)and regeneration.This work paves the way for well-defined self-organized electronics in animal tissue to modulate biological functions and in vivo biofabrication of hybrid functional materials and devices.
