Eco-concrete with recycled aggregate functionalized with phase change materials...
Jia, Zhiyou; Cunha, Sandra Raquel Leite; Aguiar, J. L. Barroso de; Chen, BingWith urbanization and population growth, construction and demolition waste generate a significant environ mental burden. Recycling construction waste and utilizing clean energy sources are crucial for sustainable development. The recycled aggregates in this study are composed of various types of construction materials, such as concrete, bricks, ceramics, plastics, etc. This study modified the recycled aggregate...
Performance of concrete with demolition waste and PCM under high temperature ra...
Jia, Zhiyou; Cunha, Sandra Raquel Leite; Aguiar, J. L. Barroso de; Chen, BingConcrete is considered an incombustible material, however, the investigation of the strength behavior under high-temperature (fire) conditions is crucial for assessing the safety impact on structures. Additionally, pure paraffin (PP), as the most common phase change material (PCM), was used in construction materials. In this work, the functionalization of demolition waste (DW) was prepared through absorption of...
A Nonribosomal Peptide Synthase Gene Driving Virulence in Mycobacterium tubercu...
Bhatt, Kiranmai; Machado, Henrique Pedro Pereira Silva Amaral; Osório, Nuno S.; Sousa, Jeremy; Cardoso, Filipa; Magalhães, Carlos André RodriguesNonribosomal peptide synthases produce short peptides in a manner that is distinct from classical mRNA-dependent ribosome-mediated translation. The Mycobacterium tuberculosis genome harbors a nonribosomal peptide synthase gene, nrp, which is part of a gene cluster proposed to be involved in the biosynthesis of isonitrile lipopeptides. Orthologous clusters are found in other slow-growing pathogenic mycobacteria ...
