Design Principles for High-Capacity Mn-Based Cation-Disordered Rocksalt Cathodes [PDF]

open access: yes, 2020
Mn-based Li-excess cation-disordered rocksalt (DRX) oxyfluorides are promising candidates for next-generation rechargeable battery cathodes owing to their large energy densities, the earth abundance, and low cost of Mn.

Attack of carbonic anhydride and hydrogen sulfide on API class H cement slurries exposed to saline formation waters

open access: yesMateriales de Construccion, 2011
This paper discusses the attack of the major ions (sulfate, chloride, and magnesium) and sour gases, present in natural gas (CO2 y SH2), on API class H cement, the type used in gas wells under high pressure and temperature.

Distance measures in gravitational-wave astrophysics and cosmology

open access: yes, 2020
We present quantities which characterize the sensitivity of gravitational-wave observatories to sources at cosmological distances. In particular, we introduce and generalize the horizon, range, response, and reach distances.

Controlling dynamic recrystallization via modified LPSO phase morphology and distribution in Mg-Gd-Y-Zn-Zr alloy

open access: yesJournal of Magnesium and Alloys, 2023
Featured initial microstructures of Mg-11Gd-4Y-2Zn-0.5Zr alloy (wt%) were obtained by adjusting temperatures of solid solution and cooling methods, including island intergranular 18R and 14H LPSO phases with low-density stacking faults, differentially ...

Some Observations on Non-covariant Gauges and the epsilon-term

open access: yes, 2002
We consider the Lagrangian path-integrals in Minkowski space for gauges with a residual gauge-invariance. From rather elementary considerations, we demonstrate the necessity of inclusion of an epsilon-term (even) in the formal treatments, without which ...

Functional analysis of enhancer elements regulating the expression of the Drosophila homeodomain transcription factor DRx by gene targeting

open access: yesHereditas, 2021
Background The Drosophila brain is an ideal model system to study stem cells, here called neuroblasts, and the generation of neural lineages. Many transcriptional activators are involved in formation of the brain during the development of Drosophila ...
