The dynamics of ion transport at nanostructured substrate–solution interfaces play vital roles in highdensity energy conversion, stochastic chemical sensing and biosensing, membrane separation, nanofluidics and fundamental nanoelectrochemistry. Further advancements in these applications require a fundamental understanding of ion transport at nanoscale interfaces. The understanding of the dynami...

objective(s):   the production of nano-hydroxyapatite by two encapsulated bacterial strains was the goal of current research.  materials and methods:   serratia marcscens atcc 14756 and pseudomonas aeruginosa ptcc 1570 were used by two methods including encapsulated form in 2% (w/v) alginate sodium powder and inoculated form (10%) in nutrient broth medium containing alginate sodium blank beads....

Nanoscale zero-valent iron (nZVI) has become a new and ecofriendly adsorbent material with promising applications. Herein, hydrotalcite-supported nanoscale (nZVI@H) is synthesized for the first time used testing removal of methylene blue (MB) in an aqueous solution. The successful fabrication nZVI@H characterized by SEM, BET, XRD, FTIR zeta-potential analyses. results showed that 99.6% MB remov...

Zero-valent iron nanoparticle technology is becoming an increasingly popular choice for treatment of hazardous and toxic wastes, and for remediation of contaminated sites. In the U.S. alone, more than 20 projects have been completed since 2001. More are planned or ongoing in North America, Europe, and Asia. The diminutive size of the iron nanoparticles helps to foster effective subsurface dispe...

while the application of optical and photonic technologies in the communications, computing, medicine and industrial manufacturing has been growing rapidly, the miniaturization of these technologies has been slow due to the limitation on the diffraction. however, the developments of nanoscale components and guiding methods are continuing with a rapid pace. since waveguiding is a fundamental iss...

a new efficient and practical method for the room-temperature reduction of aromatic nitro compounds employing feso4. 7h2o, nabh4, h3pw12o40 system in h2o under mild conditions is reported. the method is simple, inexpensive, easily scaled-up and applicable for the large scale preparation of different substituted anilines.
