Geothermal energy piles are a quite recent renewable energy technique where geothermal energy in the foundation of a building is used to transport and store geothermal energy. In this paper, a structural-functional integrated cement-based composite, which can be used for energy piles, was developed using expanded graphite and graphite nanoplatelet-based composite phase change materials (CPCMs)....
the United Provinces? The rice in their diet may give them an excess of carbon but the dal does not appear to provide anything like a sufficiency of protein (containing nitrogen). For days together they will dispense with it altogether and live on rice made acceptable with chilli paste. Does the dal provide them with the subtle nitrogen binding factor which enables the natural order of plants p...
A disposable amperometric biosensor for commercial use to detect hydrogen peroxide has been developed. The sensor is based on screen-printed carbon paste electrodes modified by electropolymerization of pyrrole with horseradish peroxidase (HRP) entrapped. The facture techniques of fabricating the enzyme electrodes are suitable for mass production and quality control. The biosensor shows a linear...
in the present study, a new chemically modified carbon paste electrode (cpe) is constructed for rapid, accurate, simple, highly sensitive, and selective determination of mo (vi) using differential pulse voltammetry. the electrode was prepared using magnetic nickel zinc ferrite nanocomposite (ni0.5zn0.5fe2o4), as the modifier in cpe (ni0.5zn0.5fe2o4/cpe). mo (vi) was determined after preconcentr...
This contribution is based on our presentation at the 1 International Symposium on Sensor Science, Paris, 16-20 June 2003. It presents recent results regarding the electrochemical determination of submicromolar and nanomolar concentrations of various carcinogenic substances (nitrated polycyclic aromatic hydrocarbons, heterocyclic compounds, azo compounds, aromatic amino compounds, etc.) using b...
