Transcriptomic Analysis Reveals Competitive Growth Advantage of Non-pigmented Mutants.

is a common bacterium well-known for the red secondary metabolite prodigiosin. However, color mutants have long been described. Non-pigmented strains can be found to exist both naturally and under laboratory conditions.

Aluminum-Tailored Energy Level and Morphology of Co Al O Porous Nanosheets toward Highly Efficient Electrocatalysts for Water Oxidation.

Tuning energy levels plays a crucial role in developing cost-effective, earth-abundant, and highly active oxygen evolution catalysts. However, to date, little attention has been paid to the effect of using heteroatom-occupied lattice sites on the energy level to engineer electrocatalytic activity. In order to explore heteroatom-engineered energy levels of spinel Co O for highly-effective oxygen electrocatalysts, herein Al atoms are directly introduced into the crystal lattice by occupying the Co ions in the tetrahedral sites and Co ions in the octahedral sites (denoted as Co and Co , respectively).
