conclusions the ammonia degassing is a simple and suitable technology for ammonia removal at high concentration. undesirable removal efficiency (17%, 35.5% and 31%) can be occurred in suitable ph 11 in the presence of lower ammonia concentrations (50, 100 and 200 mg/l). results according to obtained results, the maximum removal efficiencies were determined 17%, 35.5%, 31%, 66%, and 85.5%, for 5...

The revelation of protein-protein interactions is one of the main preoccupations in the eld of proteomics. Nanoplasmonics has emerged as an attractive surface-based technique because of its ability to sense protein binding under physiological conditions in a label-free manner. Here, we present a detailed experimental study of the use of aperiodic photonic nanocavities for plasmonic Surface Enha...

This paper presents a method for extraction and analysis of curve–type structures which consist of disconnected components. Such structures are found in electron–microscopy (EM) images of metal nanograins, which are widely used in the field of nanosensor technology. The topography of metal nanograins in compound nanomaterials is crucial to nanosensor characteristics. The method of completing su...

A comprehensive understanding of ROS (reactive oxygen species)-dependent cellular interaction requires the previously unmet ability to simultaneously monitor the intra- and extra-cellular environments. The present review assesses the potential of novel electrochemical and fluorescent-based nanosensor approaches to address the limitations of existing techniques for ROS analysis. Data generated b...

Nanoparticles are increasingly popular choices for labeling and tracking cells in biomedical applications such as cell therapy. However, all current types of nanoparticles fail to provide real-time, noninvasive monitoring of cell status and functions while often generating false positive signals. Herein, a nanosensor platform to track the real-time expression of specific biomarkers that correla...

increasing the concentration of ammonia in water can cause fish death. this study was conducted to compare the performance of conditioned activated carbon and zeolite in ammonia (tan = total ammonia nitrogen) removal in a simulated transport of rainbow trout fry in 40-liter plastic bags. hence, responses of zeolite and conditioned activated carbon in ammonia (tan) removal at different concentra...

In vivo wireless nanosensor networks (iWNSNs) consist of nanosized communicating devices, which can operate inside the human body in real time. iWNSNs are at the basis of transformative healthcare techniques, ranging from intra-body health monitoring systems to drug delivery mechanisms. In this talk, the state of the art and open challenges in the realization of iWNSNs will be presented. Novel ...

Bis-phosphine oxides can be selectively reduced to bis-phosphine monoxides under exceptionally mild conditions using triflic anhydride and a thiol.

Two novel Sb(III) and Sb(V) peri-substituted acenaphthene phosphorus−antimony compounds were prepared. The compound, 1, was prepared via reacting the organolithium precursor with dichloro(p-tolyl)Stibine, 2 by chlorination of 1. Both 1 characterized multinuclear (1H, 13C 31P) NMR spectroscopy, their molecular structures resolved single-crystal X-ray diffraction. show a dative P−Sb interaction a...

aluminium phosphide (alp) is used to kill rodents in grain storage. it produces phosphine gas which is toxic for mitochondria. the exact mechanism of action is unclear, but phosphine is thought to produce toxicity by blocking cytochrome-c oxidase, which inhibits oxidative phosphorylation and result in cell death. this poisoning has a high mortality, and survival is unlikely if more than 1.5 g i...
