TL;DR: A review of the application of algae based microbial fuel cells for bioelectricity production, mainly focusing on the use of algae in the cathodic compartment, microalgae in the anodic compartment and the main interactions between the compartments affecting the bioelectric power production can be found in this article.
Abstract: Microalgae based microbial fuel cells are efficient systems to remove nitrogen, phosphorous and CO2 from wastewater, to produce bioelectricity and value-added products from microalgal biomass. Microalgae can be used in MFCs as algae assisted cathode systems, microbial carbon capture cells or sediment microbial fuel cells as well as photosynthetic microalgae microbial fuel cell. These MFCs are shown efficient for CO2 capture with a low risk of carbon emission, N and P removal via symbiotic interactions of microalgae-bacteria consortia in wastewater treatment along with power generation. The oxygen production by microalgae during the light period reduces the need for external oxygen supply for cathodic reactions, which is advantageous for reducing the aeration cost, as otherwise power needs to be supplied for mechanical aeration. Utilization of algal biomass harvested from the cathodic compartment requires a pretreatment in a biorefinery concept. This still remains a major drawback, but current advances towards the choice of a biofilm on the cathode allow for further recovery of value-added products from algal biomass. Alternatively, the algal biomass can be utilized as the sole feedstock in the anodic compartment. This paper reviews the application of algae based microbial fuel cells for bioelectricity production, mainly focusing on the use of algae in the cathodic compartment, microalgae in the anodic compartment and the main interactions between the compartments affecting the bioelectricity production.

TL;DR: In this paper, hydrogen bond propensity calculations for the potential formation of adducts between pyrimethamine and dicarboxylic acids were performed to predict the possibility of the formation of molecular adduct.
Abstract: We have previously reported on hydrogen bond propensity calculations for the potential formation of adducts between pyrimethamine and dicarboxylic acids. Here we extend the range of potential synthon interactions using a variety of potential coformers. Specifically calculations were performed to predict the possibility of the formation of molecular adducts, 1a–1h, between the anti-malarial drug pyrimethamine (1) and (a) carbamazepine, (b) theophylline, (c) aspirin, (d) α-ketoglutaric acid, (e) saccharin, (f) p-coumaric acid, (g) succinimide and (h) L-isoleucine. The bonds of highest propensity were predicted between 1 and coformers (b–h), indicating a high probability of formation of adducts between 1 and b–h. In contrast the bonds of highest propensity were between reactants and the solvent for the adduct 1a, indicating either a high probability of the reactants crystallizing as solvates or incorporation of solvent into the adduct lattice. Experimental results agreed with the propensity calculations with the formation of a solvated cocrystal (1a·CH3OH). The successful application of hydrogen bond propensity calculations to the prediction of likely outcomes of these cocrystallization reactions suggests that this may be a useful tool in designing more targeted screening experiments.

TL;DR: In this paper, a study of the exclusive charmless semileptonic decays, B0→π-l+ν, B+→π 0l+n, B−→π l+n+n and B−−−n, was performed with approximately 462×106 BB pairs collected at the BABAR detector.
Abstract: We report the results of a study of the exclusive charmless semileptonic decays, B0→π-l+ν, B+→π0l+ν, B+→ωl+ν, B+→ηl+ν, and B+→η′l+ν (l=e or μ) undertaken with approximately 462×106 BB pairs collected at the Υ(4S) resonance with the BABAR detector. The analysis uses events in which the signal B decays are reconstructed with a loose neutrino reconstruction technique. We obtain partial branching fractions in several bins of q2, the square of the momentum transferred to the lepton-neutrino pair, for B0→π-l+ν, B+→π0l+ν, B+→ωl+ν, and B+→ηl+ν. From these distributions, we extract the form-factor shapes f+(q2) and the total branching fractions B(B0→π-l+ν)=(1.45±0.04stat±0.06syst)×10-4 (combined π- and π0 decay channels assuming isospin symmetry), B(B+→ωl+ν)=(1.19±0.16stat±0.09syst)×10-4 and B(B+→ηl+ν)=(0.38±0.05stat±0.05syst)×10-4. We also measure B(B+→η′l+ν)=(0.24±0.08stat±0.03syst)×10-4. We obtain values for the magnitude of the Cabibbo-Kobayashi-Maskawa (CKM) matrix element |Vub| by direct comparison with three different QCD calculations in restricted q2 ranges of B→πl+ν decays. From a simultaneous fit to the experimental data over the full q2 range and the FNAL/MILC lattice QCD predictions, we obtain |Vub|=(3.25±0.31)×10-3, where the error is the combined experimental and theoretical uncertainty.

TL;DR: In this paper, an experimental and theoretical investigation of the simultaneous absorption of CO 2 and H 2 S into aqueous blends of 2-amino-2-methyl-1-propanol (AMP) and diethanolamine (DEA) is presented, where the effect of contact time, temperature and amine concentration on the rate of absorption and selectivity were studied by absorption experiments in a wetted wall column at atmospheric pressure and constant feed gas ratio.
