Voltage losses limit the performance of organic solar cells, yet their origins are not fully understood. Now, a theoretical model encompassing electronic state hybridization and thermal population vibrational states explains reduced non-radiative voltage in efficient non-fullerene acceptor systems.

This article proposes (i) the estimation method of an expert system to predict the statuses of several agro-industrial machine rotary components by using a vibration signal acquired from a single point of the machine; and, (ii) a learning method to fit the estimation method. Both methods were evaluated in an agricultural harvester. Vibration signal data were acquired from a single point of the ...

in an attempt to determine the chemical losses of three common molluscicides, i.e. cuso4, napcp and bayer –73, in stagnant water, a solution of each of this molluscicide was applied to one or more b.truncatus habitats and outdoor aquariums. the concentration of each molluscicide in these water bodies was determined immediately after application and at fixed time intervals thereafter. the concen...
