“…Its CO emission has been recently analysed along the lines presented in the present paper using ALMA data (Tuan-Anh et al 2015). It has its axis nearly parallel to the sky plane and displays density and velocity configurations similar to case B considered in the preceding sections: two distinct regions with a rather sharp separation between them, a conical bipolar outflow and a rotating equatorial volume.…”

The unprecedented quality of the observations available from the Atacama Large Millimetre/sub-millimetre Array (ALMA) calls for analysis methods making the best of them. Reconstructing in space the morphology and kinematics of radio sources is an underdetermined problem that requires imposing additional constraints for its solution. The hypothesis of rotational invariance, which is a good approximation to, or at least a good reference for the description of the gas envelopes of many evolved stars and protostars, is particularly efficient in this role. In the first part of the article, a systematic use of simulated observations allows for identifying the main problems and for constructing quantities aimed at solving them. In particular the evaluation of the orientation of the star axis in space and the differentiation between expansion along the star axis and rotation about it are given special attention. The use of polar rather than Cartesian sky coordinates to display the results of the analysis is shown to often better match the morphology and kinematics of actual stars. The radial dependence of the gas density and temperature and the possible presence of velocity gradients are briefly considered. In the second part, these results are applied to a few stars taken as examples with the aim of evaluating their usefulness when applied to concrete cases. A third part takes stock of what precedes and formulates some guidelines for modelling the radio emission of axisymmetric radio sources, limited however to the mathematics and geometry of the problem, physics considerations being generally ignored.

“…Among the EIS spectra, the illuminated hybrid MFC shows the smallest Nyquist plot arc radii, which suggests that the TNT photoanodep hotogenerated electrons are added to the bioanode electrons and after doing work reach the air cathode.M oreover, the I-V curves for the normal and hybrid MFCs ( Figure S4) demonstrate behavior similar to that of aZ ener diode,a nd the threshold voltages (V thÀ and V th+ + )a ppear within ab ias range of AE 5V .

Photocoupled Bioanode: A New Approach for Improved Microbial Fuel Cell Performance

et al. 2017

Microbial fuel cells (MFCs) received considerable attention because of their ability to provide dual advantages of electricity generation and wastewater treatment. However, their performance is primarily limited by the slow oxygen reduction reaction (ORR). To alleviate this problem, we describe a hybrid MFC in which a conventional bioanode is coupled with a TiO2 photoanode. The photocatalytic photoanode utilizes light to provide additional photogenerated electrons to the external circuit of the MFC, which promotes the ORR, as confirmed by power density curves and electrochemical impedance spectra, resulting in improved power generation (1284±20 mW m−2) compared to that of a normal MFC (850±12 mW m−2). Furthermore, the ability of the TiO2 photoanode to reduce CO2 to methane is demonstrated.
