The purpose of this minireview is to highlight the early observations that led to the discovery of the physico-chemical properties of the phycobiliproteins, their structure and function, and to their architectural organization in supramolecular complexes, the phycobilisomes. Generally attached on the stromal surface of the thylakoid membranes in both prokaryotic (cyanobacteria) and eukaryotic c...

   This paper reviews some progressive studies and innovations in cement and concrete materials in nano field. Due to the widespread acceptance of the special properties of nano materials and using them for engineering concrete performance, understanding and directing their properties are not achievable without instructing concepts and investigating interactions among components. Due to ach...
