Abstract Low-risk removal of embedded surface soiling on delicate heritage objects can require novel alternatives to traditional cleaning systems. Edvard Munch’s monumental Aula paintings (1911–16) have a long history exposure atmospheric pollution and campaigns that compromised the appearance condition these important artworks. Soiling from porous water-sensitive, unvarnished oil continues be ...
The Atacama Desert receives the highest levels of solar irradiance in world with an annual average 2500 kWh/m2 for global horizontal and 3500 direct normal irradiance. One challenges is large portion ultraviolet light. This part spectrum be detrimental encapsulant materials, reducing their lifetime. To develop a module adapted to conditions, it imperative have standardized information from firs...
Capacitive electrodes overcome electrode polarization problems and enable noninvasive measurements hence they do not obstruct flow and avoid corrosion, wearing and soiling. However, their impedance is much higher than that of direct contact electrodes and, to reduce it, the measurement frequency must be increased, which worsens the effects of stray interelectrode impedance. In this paper, we an...
