Extending the capabilities of vectorial ptychography to circular-polarizing materials such as cholesteric liquid crystals.

The problem of imaging materials with circular-polarization properties is discussed within the framework of vectorial ptychography. We demonstrate, both theoretically and numerically, that using linear polarizations to investigate such materials compromises the unicity of the solution provided by this computational method. To overcome this limitation, an improved measurement approach is proposed, which involves specific combinations of elliptical polarizations.

Electrochemical performance of Paenibacillus profundus YoMME encapsulated in alginate polymer.

Gram-positive bacterium Paenibacillus profundus YoMME, entrapped in an alginate polymer onto graphite paper, preserves its extracellular electron transfer capabilities. A current density of up to 30 mA m was generated at an applied potential of -200 mV (vs. SHE).

Draft Genome Sequence of Paenibacillus profundus YoMME, a New Exoelectrogenic Gram-Positive Bacterium.

Paenibacillus profundus YoMME was isolated from the anodic biofilm of a sediment microbial fuel cell and recognized as one of the few exoelectrogenic Gram-positive bacteria, capable of transferring electrons extracellularly. Here, we report its draft genome sequence. The genome project is deposited at DDBJ/ENA/GenBank under the accession number JAJNBZ000000000.

Gram-positive bacteria covered bioanode in a membrane-electrode assembly for use in bioelectrochemical systems.

A novel strain of Gram-positive bacteria Paenibacillus profundus YoMME was recognized by sequencing of 16S rRNA gene and after that tested for exoelectrogenicity for the first time. It was found that at an applied potential of -0.195 V (vs.
