Influence of accelerated curing on the compressive strength of polymer-modified concrete

Izhar AHMAD; Kashif Ali KHAN; Tahir AHMAD; Muhammad ALAM; Muhammad Tariq BASHIR

Frontiers of Structural and Civil Engineering 2022, Volume 16, Issue 5,   Pages 589-599 doi: 10.1007/s11709-022-0789-1

Abstract: Furthermore, in designing concrete structures, compressive strength is the most significant of all parametersWhile 3-d and 7-d compressive strength reflects the strengths at early phases, the ultimate strengthThe compressive strength of EVA-modified concrete was studied by incorporating various concentrationsAn accelerated compressive strength at 3.5 hours was considered as a reference strength on the basisBased on the results of compressive strength test, it was concluded that the strength of EVA-modified

Cell-free systems in the new age of synthetic biology

Fernando Villarreal,Cheemeng Tan

Frontiers of Chemical Science and Engineering 2017, Volume 11, Issue 1,   Pages 58-65 doi: 10.1007/s11705-017-1610-x

Abstract: The advent of synthetic biology has ushered in new applications of cell-free transcription-translation systems. These cell-free systems are reconstituted using cellular proteins, and are amenable to modular control of their composition. Here, we discuss the historical advancement of cell-free systems, as well as their new applications in the rapid design of synthetic genetic circuits and components, directed evolution of biomolecules, diagnosis of infectious diseases, and synthesis of vaccines. Finally, we present our vision on the future direction of cell-free synthetic biology.
