Resumen
ABSTRACT Methylammonium and ammonium (MEP) permeases of Saccharomyces cerevisiae belong to a ubiquitous family of cytoplasmic membrane proteins that transport only ammonium (NH4 + + NH3). Transport and accumulation of the ammonium analog [14C]methylammonium, a weak base, led to the proposal that members of this family were capable of energy-dependent concentration of the ammonium ion, NH4 +. In bacteria, however, ATP-dependent conversion of methylammonium to γ-N-methylglutamine by glutamine synthetase precludes its use in assessing concentrative transport across the cytoplasmic membrane. We have confirmed that methylammonium is not metabolized in the yeast S. cerevisiae and have shown that it is little metabolized in the filamentous fungus Neurospora crassa. However, its accumulation depends on the energy-dependent acidification of vacuoles. A Δvph1 mutant of S. cerevisiae and a Δvma1 mutant, which lack vacuolar H+-ATPase activity, had large (fivefold or greater) defects in the accumulation of methylammonium, with little accompanying defect in the initial rate of transport. A vma-1 mutant ofN. crassa largely metabolized methylammonium to methylglutamine. Thus, in fungi as in bacteria, subsequent energy-dependent utilization of methylammonium precludes its use in assessing active transport across the cytoplasmic membrane. The requirement for a proton gradient to sequester the charged species CH3NH3 + in acidic vacuoles provides evidence that the substrate for MEP proteins is the uncharged species CH3NH2. By inference, their natural substrate is NH3, a gas. We postulate that MEP proteins facilitate diffusion of NH3 across the cytoplasmic membrane and speculate that human Rhesus proteins, which lie in the same domain family as MEP proteins, facilitate diffusion of CO2.

Resumen
Abstract By differential thermal analysis a new high-temperature solid phase of methylammonium bromide was found between 483 K and its “melting point” (510 K). 1H NMR absorption measurements revealed the presence of rapid 3D translational self-diffusion and overall rotation of methylammonium cations in this phase. These cationic motions are quite analogous to those of methylammonium iodide in its ionic plastic phase. Surprisingly, this plastic-like phase is metastable, the stable phase in the same temperature range being liquid.

Resumen
The optical influence of mixing methylammonium lead chlorine (MAPbCl3) with iodine and bromine was studied in this work. The spin coating method deposited three layers of perovskites (MAPbCl3, MAPbCl2I, and MAPbCl2Br) on a layer of zinc oxide (ZnO). The zinc oxide solution was prepared by dissolving dehydrated zinc acetate [Zn(CH3COO)2, 2H2O]> 99.5% purity in ethanol to give a 0.5 M solution. The perovskite solutions were prepared using lead chloride (PbCl2), methylammonium chloride (MACl), methylammonium iodide (MAI), and methylammonium bromide (MABr). The precursor containing iodine was dissolved in N, N-dimethylformamide (DMF) and the others in dimethyl sulphoxide (DMSO 99.9%). The films produced were characterized by UV-Visible. The analysis showed that the sample mixed with iodine has good properties. This sample absorbs the most and has a small band gap of 2 eV. The degradation study reveals that the unmixed sample (MAPbCl3) is the most stable.

Resumen
Effects of basolateral monovalent cation replacements (Na+ by Li+, K+, Cs+, methylammonium, and guanidinium) on permeability to86Rb of volume-sensitive cation channels (VSCC) in the basolateral membrane and on regulatory volume decrease (RVD), elicited by a hyposmotic shock, were studied in A6 epithelia in the absence of apical Na+ uptake. A complete and quick RVD occurred only when the cells were perfused with Na+ or Li+ saline. With both cations, hypotonicity increased basolateral86Rb release ([Formula: see text]), which reached a maximum after 15 min and declined back to control level. When the major cation was K+, Cs+, methylammonium, or guanidinium, the RVD was abolished. Methylammonium induced a biphasic time course of cell thickness (Tc), with an initial decline of Tc followed by a gradual increase. With K+, Cs+, or guanidinium, Tc increased monotonously after the rapid initial rise evoked by the hypotonic challenge. In the presence of K+, Cs+, or methylammonium,[Formula: see text] remained high during most of the hypotonic period, whereas with guanidinium blockage of[Formula: see text] was initiated after 6 min of hypotonicity, suggesting an intracellular location of the site of action. With all cations, 0.5 mM basolateral Gd3+ completely blocked RVD and fully abolished the [Formula: see text] increase induced by the hypotonic shock. The lanthanide also blocked the additional volume increase induced by Cs+, K+, guanidinium, or methylammonium. When pH was lowered from 7.4 to 6.0, RVD and[Formula: see text] were markedly inhibited. This study demonstrates that the VSCCs in the basolateral membrane of A6 cells are permeable to K+, Rb+, Cs+, methylammonium, and guanidinium, whereas a marked inhibitory effect is exerted by Gd3+, protons, and possibly intracellular guanidinium.

Resumen
ABSTRACT Corynebacterium glutamicum has two different Amt-type proteins. While AmtB has a low substrate affinity and is not saturable up to 3 mM methylammonium, AmtA has a high substrate affinity and mediates saturable, membrane potential-dependent transport, resulting in a high steady-state accumulation of methylammonium, even in the absence of metabolic trapping.

Resumen
Ab initio and semi-empirical molecular orbital theory has been used to study the reaction pathways of the Stevens rearrangement of the prototype methylammonium methylide and methylammonium formylmethylide . For both reactions, the stepwise (free radical) process is predicted to require less energy than the concerted rearrangement (in accordance with experimental suggestions). With inclusion of electron correlation, the energy difference between these pathways is reduced; however, for the smaller system at the CCSD/6-31G(d) level of theory, the free radical process is still favoured by over 180 kJ mol-1. For both systems, the concerted transition structures for the pericyclic mechanisms reveal that some amount of bonding is retained in these formally symmetry-forbidden processes.

Resumen
This work demonstrates a sequential deposition of lead iodide followed by methylammonium iodide using the industrially compatible slot-die coating method that produces homogeneous pin-hole free films without the use of the highly toxic dimethylformamide. This is achieved through the careful selection and formulation of the solvent system and coating conditions for both the lead iodide layer and the methylammonium iodide coating. The solvent system choice is found to be critical to achieving good coating quality, conversion to the final perovskite and for the film morphology formed. A range of alcohols are assessed as solvent for methylammonium iodide formulations for use in slot-die coating. A dimethylsulfoxide solvent system for the lead iodide layer is shown which is significantly less toxic than the dimethylformamide solvent system commonly used for lead iodide deposition, which could find utility in high throughput manufacture of perovskite solar cells.

We present a critical review of the effects of processing conditions on the morphology of methylammonium lead iodide (CH3NH3PbI3) perovskite solar cells. Though difficult to decouple from synthetic and film formation effects, a single morphological feature, specifically grain size, has been evidently linked to the photovoltaic performance of this class of solar cells. Herein, we discuss experimental aspects of optimizing the (a) temperature and time of annealing, (b) spin-coating parameters, and (c) solution temperature of methylammonium iodide (MAI) solution.

Resumen
Films or powders of hybrid methylammonium copper halide perovskite exhibit photocatalytic activity for overall water splitting in the vapor phase in the absence of any sacrificial agent, resulting in the generation of H2 and O2, reaching a maximum production rate of 6 μmol H2 × g cat−1h−1 efficiency. The photocatalytic activity depends on the composition, degreasing all inorganic Cs2CuCl2Br2 perovskite and other Cl/Br proportions in the methylammonium hybrids. XRD indicates that MA2CuCl2Br2 is stable under irradiation conditions in agreement with the linear H2 production with the irradiation time. Similar to copper analogue, hybrid methylammonium lead halide perovskites also promote the overall photocatalytic water splitting, but with four times less efficiency than the Cu analogues. The present results show that, although moisture is strongly detrimental to the photovoltaic applications of hybrid perovskites, it is still possible to use these materials as photocatalysts for processes requiring moisture due to the lack of relevance in the photocatalytic processes of interparticle charge migration.

Resumen
The methylammonium bismuth iodide (MBI), a promising lead (Pb)-free perovskite solar cells (PeSC’s) material, is suitable for photovoltaic applications due to less toxic and good stability. Herein, the effect of MAI (methylammonium iodide) on the structural, morphological, optical properties and solar cells performance of bismuth-perovskite solar cells (Bi-PeSC’s) by all-solution processed multi-step spin coating is investigated. The scanning electron microscope (SEM) morphology visually depicts that with the increase of methylammonium iodide (MAI) precursor molar ratio in bismuth (III) iodide (BiI3) x [= [MAI]/([MAI]+[BiI3])] from x=0 to x=0.8, the morphological phase changed significantly. Likewise, the x-ray diffraction (XRD) peak of BiI3 at 12.78o (003) is tremendously changed in the phase and intensity. At the same time, the solar cell performances exhibit gradual increment as increasing the content of MAI in BiI3 and the open circuit voltage (Voc) is exceeded four-times of the minimum MAI molar ratio. The maximum Voc obtained by multilayer Bi-PeSC’s is 0.34V and an efficiency shows an increment up to 0.0037% at MAI molar ratio, x=0.8. In brief, our findings suggested the improvement of Bi-perovskite absorber layer in the future.

Resumen
We show that the addition of 1% (v/v) nitrobenzene within the perovskite formulation can be used as a method to improve the power conversion efficiency and reliability performance of methylammonium-free (CsFA) inverted perovskite solar cells. The addition of nitrobenzene increased power conversion efficiency (PCE) owing to defect passivation and provided smoother films, resulting in hybrid perovskite solar cells (PVSCs) with a narrower PCE distribution. Moreover, the nitrobenzene additive methylammonium-free hybrid PVSCs exhibit a prolonged lifetime compared with additive-free PVSCs owing to enhanced air and moisture degradation resistance.

Resumen
The synthesis and X-ray crystal structure of the new tren derivative N,N,N-tris(2-aminoethyl)-N-methylammonium chloride trihydrochloride are detailed. The compound was synthesized by methylation of tris(2-phthalimido-ethyl)amine using dimethyl sulfate followed by acid deprotection. N,N,N-Tris(2-aminoethyl)-N-methylammonium chloride trihydrochloride crystallizes in the hexagonal space group P63 and the X-ray crystal structure reveals one-dimensional chains of cations extensively hydrogen-bonded to two different types of chloride counter ions, one of which exhibits a coordination number of nine. The cation is a poor ligand towards both CoIII and NiII.

Resumen
In the title compound, 4CH6N+·C10H2O8 4−·2H2O, the complete C10H2O8 4− anion is generated by inversion; one of the unique carboxylate groups is almost coplanar with the benzene ring, perhaps as the result of intramolecular C—H...O interactions, and the other is almost perpendicular. A network of O—H...O and N—H...O hydrogen bonds helps to consolidate the crystal packing.
