Fluoride (F), a powerful oxidizing agent, is used in a variety of industries in China. Health problems among industrial workers due to F poisoning are on the rise. Long-term F exposure, together with varieties of relevant factors, leads to high F burden [blood fluoride (BF), urinary fluoride (UF)], which can finally result in F bone injury (1). As F burden is the major cause of F bone injury, t...

There are several methods of fabricating nanogaps with controlled spacings, but the precise control over the sub-nanometer spacing between two electrodes-and generating them in practical quantities-is still challenging. The preparation of nanogap electrodes using nanoskiving, which is a form of edge lithography, is a fast, simple and powerful technique. This method is an entirely mechanical pro...

We have developed a manufacturing process for organic thin-film transistors and organic complementary circuits in which a microcontact-printed phosphonic acid self-assembled monolayer is employed first as an etch resist to pattern aluminum gate electrodes by wet etching and then as the gate dielectric of the same device. To our knowledge, this is the first report of a printing process for elect...

The main objective of this paper is to study the performance of the various combinations of electrodes which plays an important role in the microbial fuel cells for the generation of electricity. The present work is an experimented investigation concerned with selection of the electrodes for the best performance of a microbial fuel cell. The various combinations of anode/cathode materials like ...

Removal of algae in the reservoir water was studied by electroflocculation using a bipolar cell with aluminum electrodes and flocculation by treatment with commercial alum. Comparison of both the methods is discussed.

introduction thermal processing has a huge impact on the textural attribute of the final food product and texture is a major factor contributing the overall quality of food. ohmic heating is an advanced thermal processing method in which heat is internally generated within foods by passing an alternating electric current through them. ohmic heating can volumetrically heat the entire mass of a f...

Sugar industry is an oldest accommodates industry in the world. It required and discharges a large amount of water for processing. Removal of chemical oxygen demand and color through the electrochemical process including hybrid iron and aluminum electrode was examined for the treatment of cane-based sugar industry wastewater. Most favorable condition at pH 6.5, inter-electrode gap 20 mm, curren...

A nanoporous membrane system with directed flow carrying reagents to sequentially attached enzymes to mimic nature’s enzyme complex system was demonstrated. Genetically modified glycosylation enzyme, OleD Loki variant, was immobilized onto nanometer-scale electrodes at the pore entrances/exits of anodic aluminum oxide membranes through His6-tag affinity binding. The enzyme activity was assessed...

OBJECTIVE To evaluate fluoride and aluminum concentration in herbal, black, ready-to-drink, and imported teas available in Brazil considering the risks fluoride and aluminum pose to oral and general health, respectively. METHODS One-hundred and seventy-seven samples of herbal and black tea, 11 types of imported tea and 21 samples of ready-to-drink tea were divided into four groups: I-herbal t...
