Restructuring a Complex Genetic Function on Episomal Vectors in .

Genetic functions have evolved over long timescales and can be encoded by multiple genes dispersed in different locations in genomes, and although contemporary molecular biology enables control over single genes, more complex genetic functions remain challenging. Here, we study the restructuring and mobilization of a complex genetic function encoded by 10 genes, originally expressed from four operons and two loci on the genome. We observe subtle phenotypic differences and reduced fitness when expressed from episomal DNA and demonstrate that mutations in the transcriptional machinery are necessary for successful implementation in different bacteria.

Synthesis and characterization of an organic-inorganic hybrid crystal: 2[Co(en)](VO)·4HO.

Organic-inorganic hybrid crystals have diverse functionalities, for example in energy storage and luminescence, due to their versatile structures. The synthesis and structural characterization of a new cobalt-vanadium-containing compound, 2[Co(en)](VO)·4HO (1) is presented. The crystal structure of 1, consisting of [Co(en)] complexes and chains of corner-sharing (VO) tetrahedra, was solved by single-crystal X-ray diffraction in the centrosymmetric space group P1.

Impact of geometric correction on echo-planar imaging-based apparent diffusion coefficient maps for abdominal radiotherapy.

. The apparent diffusion coefficient (ADC) extracted from diffusion-weighted magnetic resonance imaging (DWI) is a potential biomarker in radiotherapy (RT). DWI is often implemented with an echo-planar imaging (EPI) read-out due to speed, but unfortunately low geometric accuracy follows.

Formation Mechanism and Hydrothermal Synthesis of Highly Active IrRuO Nanoparticles for the Oxygen Evolution Reaction.

Iridium dioxide (IrO), ruthenium dioxide (RuO), and their solid solutions (IrRuO) are very active electrocatalysts for the oxygen evolution reaction (OER). Efficient and facile synthesis of nanosized crystallites of these materials is of high significance for electrocatalytic applications for converting green energy to fuels (power-to-X). Here, we use X-ray scattering to examine reaction conditions for different Ir and Ru precursors resulting in the development of a simple hydrothermal synthesis route using IrCl and KRuO to obtain homogeneous phase-pure IrRuO nanocrystals.

Continuous-Flow Synthesis of ZnMnS Nanoparticles at Ambient Conditions.

With its large direct band gap and good chemical stability, ZnS is suitable for many applications, including light-emitting diodes, panel displays, and photodetection. Here, nanoparticles of ZnS are synthesized phase pure under ambient conditions by precipitation in a simple and scalable continuous-flow reactor. Furthermore, different degrees of Zn substitution with Mn have been investigated, ZnMnS, with = 0.
