there was a turning point in each period of time which human has discovered a new sight about the world and nature order in a way, and then has presented this relation by numeral, artful and industrial language. biourbanism focuses on the urban organism, considering it as a hyper complex system, according to its internal and external dynamics and their mutual interactions. nowadays when it is t...

This work aims to investigate the influence of temperature and chemical impregnation in textural morphological composition bio-adsorbent bio-adsorption via thermal cracking seeds açaí. The experiments were carried out at 400 °C 450 using a pilot scale reactor. efficiency organic process was calculated terms liquid solid products selected with NaOH, mainly that had greater product conversion. el...

PFAS are commonly found pollutants in soil and water bodies. Of all the that found, PFOA PFOS most hazardous ones. The review focuses upon Adsorption, Sonochemical Degradation, Photocatalysts, Bio-remediation as techniques for removal degradation of PFA.

Background & Aims of the Study: Heavy metals discharge to environment is a worldwide problem growing in scale. When they accumulate in the environment and in food chains, they can profoundly disrupt biological processes. Peganum Harmala Seeds (PHS) was used as a bio-sorbent, using a continuous system for removing Pb2+, Co2+, Ni2+ and Cu2+ ions from aqueous solutions. ...

Pressure swing adsorption (PSA) technology is used in various applications. PSA a cost-effective process with the ability to produce high-purity bio-hydrogen (99.99%) high recovery rates. In this article, for production of proposed; it uses two columns packed type 5A zeolite, and has four-step configuration (adsorption, depressurization, purge, repressurization) regeneration beds. The aim work ...

Surface plasmon resonance (SPR) technique offers a robust label-free approach applicable in various investigations including binding affinity, specificity and kinetics of biological macromolecules (e.g., peptides, proteins and nucleotidase) and small molecules. SPR provides extremely important data on the kinetics and affinity of substances examined, through which bio-specific interaction(s) ca...

The bonding configuration and the heat of adsorption of a furfural molecule on the Pd(111) surface were determined by ab initio density-functional-theory calculations. The dynamics of pure liquid water, the liquid-solid interface formed by liquid water and the Pd(111) surface, as well as furfural at the water-Pd interface, were investigated by ab initio molecular dynamics simulations at finite ...

Over the last decade, nano-sized particles of noble metals with surface plasmonresonance properties have found numerous applications in nanotechnology and scientific research, including diverse biological and biomedical fields (for recent reviews see, e.g. [1–9]. This also refers to (bio) functionalised metal nanoparticles, where the term ‘‘functionalisation’’ (or ‘‘biofunctionalisation’’) mean...

This paper evaluates the effects of microbiologically influenced corrosion (MIC) on fatigue-crack growth of candidate materials useful in expanding bio-ethanol usage, including a storage-tank steel (ASTM A36) and two pipeline steels (API 5L X52 and X70). The microbiological species sampled and cultivated from an ethanol fuel production stream are responsible for both acetic acid and hydrogen su...
