Green Solutions for Urban Sustainability: Photobioreactors for Algae Cultivation on Façades and Artificial Trees

Development of suitable photobioreactors for CO2 sequestration addressing global warming using green algae and cyanobacteria.

CO(2) sequestration by cyanobacteria and green algae are receiving increased attention in alleviating the impact of increasing CO(2) in the atmosphere. They, in addition to CO(2) capture, can produce renewable energy carriers such as carbon free energy hydrogen, bioethanol, biodiesel and other valuable biomolecules. Biological fixation of CO(2) are greatly affected by the characteristics of the...

The Green Future: Architecture + Sustainability; Green Architecture and Impacts of it on Urban Planning and Urban Design

Green architecture, or green design, is an approach to building that minimizes harmful effects on human health and the environment. The “green” architect or designer attempts to safeguard air, water, and earth by choosing eco-friendly building materials and construction practices. So, green architecture is Building and structure design philosophy that aims at minimal use of non-renewable and/or...

Wildflower green roofs for urban landscaping, ecological sustainability and biodiversity

The aim of this trial was to test a wildflower roof in order to show how a country landscape fits in an urban environment. The bio-agronomic performance, the biodiversity dynamics during the two-years experiment, and the pollinating fauna, were analysed. Each plant group was able to efficiently colonize the surface of the roof though in different periods and with various modalities. Thermal ins...

Green Cities, the Search for Sustainability, and Urban Environmental History

Antimicrobial activity of five species of green – blue algae and three species of green algae for Mashhad.

Background & Aim: In this study, is done during one-year research on blue–green and green algae for antimicrobial activity in Mashhad suburb. Aqueous, ether, and methanol extracts from 44 species blue – green algae and green algae were examined for antimicrobial properties against four bacteria (tow positive gram bacteria and tow negative gram bacteria) and tow fungous. Material & Methods: Amo...
