1Laser-induced graphitization of a forest-based ink for use in flexible and printed electronics显示文摘Laser-induced graphitization(LIG)is a method of converting a carbon-rich precursor into a highly conductive graphite-like carbon by laser scribing.This method has shown great promise as a versatile and low-cost patterning technique.Here we show for the first time how an ink based on cellulose and lignin can be patterned using screen printing followed by laser graphitization.Screen printing is one of the most commonly used manufacturing techniques of printed electronics,making this approach compatible with existing processing of various devices.The use of forest-based materials opens the possibility of producing green and sustainable electronics.Pre-patterning of the ink enables carbon patterns without residual precursor between the patterns.We investigated the effect of the ink composition,laser parameters,and additives on the conductivity and structure of the resulting carbon and could achieve low sheet resistance of 3.8Ωsq^(−1) and a high degree of graphitization.We demonstrated that the process is compatible with printed electronics and finally manufactured a humidity sensor which uses lignin as the sensing layer and graphitized lignin as the electrodes.Jesper Edberg Robert Brooke Omid Hosseinaei Andreas Fall Kosala Wijeratne Mats Sandberg 2020npj Flexible Electronics2020,4,1:1

3Land use impacts on parasitic infection: a cross-sectional epidemiological study on the role of irrigated agriculture in schistosome infection in a dammed landscape显示文摘Background:Water resources development promotes agricultural expansion and food security.But are these benefits offset by increased infectious disease risk?Dam construction on the Senegal River in 1986 was followed by agricultural expansion and increased transmission of human schistosomes.Yet the mechanisms linking these two processes at the individual and household levels remain unclear.We investigated the association between household land use and schistosome infection in children.Andrea J.Lund David HRehkopf Susanne HSokolow MMoustapha Sam Nicolas Jouanard Anne-Marie Schacht Simon Senghor Assane Fall Gilles Riveau Giulio ADe Leo David Lopez-Carr 2021Infectious Diseases of Poverty2021,10,2:0
