In this work, the inverse fluidized-bed bio-adsorption column is applied for first time and demonstrated using torrefied rice husk (TRH) removal of methylene blue from solution. The bio-adsorbents were characterized by BET, FI-IR, SEM. adsorption TRH becomes saturated in 95-min continuous adsorption, during which breakthrough 22 min, overall MB (R) 84%, capacity (Qexp) on 6.82 mg g?1. These cha...

In our previous study, as natural food colorants and antioxidants, the color and content stabilities of Schisandra chinensis (S. chinensis) anthocyanins were investigated. In this work, the purification process parameters of S. chinensis anthocyanins using a macroporous resin and gel filtration chromatography were evaluated. The optimized parameters of static adsorption and desorption were as f...

BACKGROUND Protein adsorption is the first of a complex series of events that regulates many phenomena at the nano-bio interface, e.g. cell adhesion and differentiation, in vivo inflammatory responses and protein crystallization. A quantitative understanding of how nanoscale morphology influences protein adsorption is strategic for providing insight into all of these processes, however this und...

This investigation provides new insights into the effective removal of tetrafluoroborate (BF4-) by means of bio-sorption on waste generated in the orange juice industry. It was undertaken to evaluate the feasibility of zirconium (IV)-loaded saponified orange waste gel for BF4- removal from an aqueous solution. Batch adsorption experiments were carried out to study the influence of various facto...

We present a molecular theory to study the adsorption of different species within pH-sensitive hydrogel nanofilms. The theoretical framework allows for a molecular-level description of all the components of the system, and it explicitly accounts for the acid-base equilibrium. We concentrate on the adsorption of hexahistidine, one of the most widely used tags in bio-related systems, particularly...

Bioelectronics has attracted increasing interest in recent years because of their applications in various disciplines, such as biomedical. Development of efficient bio-nano hybrid materials is a new move towards revolution of nano-bioelectronics. A novel nano-bio hybrid electrode based on ZnO–protein for bioelectronics applications was prepared and characterized. The electrode was made by coval...
