Conventional ion-selective electrodes with a liquid junction have the disadvantage of potential drift. All-solid-state ion-selective electrodes with solid contact in between the metal electrode and the ion-selective membrane offer high capacitance or conductance to enhance potential stability. Solution-casted chitosan/Prussian blue nanocomposite (ChPBN) was employed as the solid contact layer f...

Moderate levels of dioctyl phthalate, hydrogen chloride and carbon monoxide are features of ambient air in production of linoleum, polyvinylchloride decorative filv and in other modern plastic materials production shops. The workers were diagnosed as having latent signs of neurotoxicity--vegetative dysfunction with prevalent parasympathetic tone and inactive polyneuropathy shown by electroneuro...
