Understanding the interactions between natural organic matter (NOM) and zero-valent iron nanoparticles (nano-Fe0) and magnetite nanoparticles (nano-Fe3O4) is essential for evaluating their performance in pollutant remediation, as well as determining their fate and transport in the environment. Batch experiments were performed to investigate the sorption/desorption behaviors of humic acid (HA) o...

abstract: application of atomic force microscope as a manipulator for pushing-based positioning of nano-particles has been of considerable interest during recent years. however a detailed modeling of the interaction forces and control on the afm tip is important for prosperous manipulation control, a reliable control of the afm tip position during the afm-based manipulation process is a main is...

CONTEXT Many synthetic bone materials have been introduced for repairing bone defects. AIM The aim of this study is to comparatively evaluate the efficacy of nano-hydroxyapatite (HA) and nano-bioglass bone materials with their traditional micro counterparts in repairing bone defects. MATERIALS AND METHODS In this prospective animal study, four healthy dogs were included. First to fourth pre...

The authors regret an oversight on their part resulting in the omission of some important information from the work. They failed to state where the proteomic analysis whose results they included in the paper has been performed. They also omitted several facts regarding the methodology of the analysis. As the authors highly regard the analytical service provided by the laboratory to which they m...

The most stringer barrier for the delivery of neurotherapeutics in-vivo is presented by the blood-brain barrier which limits the access of neurotherapeutics to the CNS effectively. Intranasal delivery of neurotherapeutics is one of the promising endeavors to surmount the blood-brain barrier, designated as direct nose to brain transport, by the passage of neurotherapeutics along the olfactory an...

Nano materials is a new type of drug carriers with very promising application. In recent years, great progress was achieved in making drugs own the characteristics of targeted and controlled release via nanotechnologies. This paper addressed the capability of nano drugs on targeting to cells, penetrating through epicyte, controlled release and the security issues resulting from its using. We ga...

A novel graphical method of analysing continuous membrane separation systems has been developed. The method is applicable to all counterand co-current membrane modules – single-stage, cascades, and membrane columns. All configurations can be broken down into “column sections”, no matter how complex the arrangement. Each column section, which resembles a typical single-stage separator, is modell...

Non-steroidal anti-inflammatory drugs (NSAIDs) and endocrine disruptors (EDCs) are among the most important categories of contaminants emerging concern (CECs), many advanced technologies have been developed for their elimination from water wastewater, including nano-zero valent iron (nZVI). This study investigates performance nZVI synthesized green tea extracts incorporated into a cationic resi...
