This paper presents a review of multielectrode array systems and sensors for electrochemical studies and corrosion monitoring. Uncoupled multielectrode arrays [also called wire beam electrodes (WBEs)] for corrosion studies were reported in 1991. Coupled multielectrode arrays were first reported in 1996 for studying the spatiotemporal electrochemical(More)
Compressively-stressed elastic films on finite-thickness viscous substrates can undergo a buckling instability that relieves stresses but destroys the planarity of the film. A linear-stability analysis is performed to determine the onset and maximally unstable mode of this buckling instability as a function of misfit strain, viscous layer thickness, and(More)
BACKGROUND The diagnosis of dental caries is fundamental to the practice of dentistry. Despite the fact that dental caries has declined considerably, it is still a problem of great importance. The reduction in caries prevalence has not occurred uniformly for all the surfaces. The greatest reduction was observed at lesions located on smooth surfaces, so that(More)
AIM The aim of these case reports is to present a treatment to promote root-end growth and apexification in nonvital immature permanent teeth in children. METHODS AND MATERIALS Three cases were presented where the calcium hydroxide and iodoform paste Metapex® was placed in the root canals of immature permanent teeth using disposable plastic tips. The(More)
— Groundwater is one of the most important natural resources. Groundwater has become a necessary resource over the past decades due to the increase in its usage for drinking, water supply, irrigation and industrial uses etc. Groundwater resources are now facing threats due to anthro-progenic activities. Mapping of spatial variability of groundwater quality(More)
The engineering and economic feasibility of large-scale electrochemical reduction of carbon dioxide to formate salts and formic acid is the focus of this Full Paper. In our study we investigated the long-term performance of tin and other proprietary catalysts in the reduction of carbon dioxide to formate/formic acid at a gas/solid/liquid interface, using a(More)
Raman spectroscopy has been identified as a potentially useful tool to collect evidence of past or present life on extraterrestrial bodies. However, it is limited by its inherently low signal strength. In this investigation, laboratory tests were conducted using surface-enhanced Raman spectroscopy (SERS) in an "inverted" mode to detect the presence of(More)
