Surface morphology and electrical properties of pulse electrodeposition of NiFe films on copper substrates in ultrasonic field by Ruthramurthy, Balachandran, Yow, Ho Kwang, Ong, Boon Hoong, Tan, Kar Ban, Kassim, Anuar, Wong, Hin Yong

“…On the other hand, the resistivity was reduced to 19.86 µωcm from 54.00 µωcm as the Ni content increased from 76.08% to 80.12 % for achieving good stoichiometry for NiFe thin films. Through the optimization study, the deposition current is observed to be the dominant factor in determining the single phase deposition of NiFe film whereas ultrasonic field and duty cycle significantly reduces the surface roughness and the spherical grain size, all of which combine to reduce film resistivity.…”

Characterization of regulatory central stalk epitopes of mycobacterial- and acetogen F-ATP synthases by Bogdanović, Nebojša

“…To utilize the hypersalinity for the energy generation, A. woodii has invented a hybrid Na+-translocating c-ring that contains the V-ATPase-like subunit c1 and F-ATP synthase ¬c2/3, arranged in the c10 ring of the c1:c2/3 stoichiometry 1:9 (6,7). The Na+-motive force operates on a similar principle found in PMF-dependant F-ATP synthases. …”

Pushing the detection of cation nonstoichiometry to the limit by Lu, Qiyang, Yildiz, Bilge

“…Nanoscale complex-oxide thin films prepared by well-established growth techniques, such as pulsed-laser deposition or molecular-beam epitaxy, often exhibit compositions that deviate from the ideal stoichiometry.

Stable aerobic and anaerobic coexistence in anoxic marine zones by Zakem, Emily Juliette, Mahadevan, Amala, Lauderdale, Jonathan, Follows, Michael J

“…The model simulates key characteristics of AMZs, such as the accumulation of nitrite and the sustainability of anammox at higher oxygen concentrations than denitrification, and articulates how microbial biomass concentrations relate to associated water column transformation rates as a function of redox stoichiometry and energetics. Incorporating the metabolic model into an idealized two-dimensional ocean circulation results in a simulated AMZ, in which a secondary chlorophyll maximum emerges from oxygen-limited grazing, and where vertical mixing and dispersal in the oxycline also contribute to metabolic co-occurrence. …”
