Background: Short-Chain Fatty Acids (SCFA; acetate, propionate and butyrate) are more and more recognised as mediators of local gut and systemic health. Quantification of SCFA in plasma and serum is challenging due to their low concentrations in human blood and the ubiquitous nature of acetate, requiring careful standardisation of the sample preparation procedure. Also the choice of the blood t...
Simple analytical formulas for micro-bending and surface scattering loss in Hollow-Core Tube Lattice Fibers are here proposed numerically validated. They can also be applied to other fibers with similar core-cladding interfaces such as Hybrid cladding Kagome-Tubular, Nested Tubes, Kagome fibers. Scaling laws both mechanisms given discussed.
satisfies it. This indicates that in the limit, as the wall thickness of the hollow tube approaches zero, the only possible mode of torsional wave propagation is the zeroth mode, as would be expected. For completeness, Fig. 1 shows the values of the characteristic numbers k'a plotted agsinst the ratio of the tube inner radii to tube outer radii for the cases calculated. This shows that torsiona...
Unlike nanoscrolls of 2D graphene, those of 2D h-BN have not been demonstrated, except for only a few experimental reports. Nanoscrolls of h-BN with high yields and reproducibility are first synthesized by a simple solution process. Inner-tube diameters of BNSs including LCAs, N-(2-aminoethyl)-3α-hydroxy-5β-cholan-24-amide, a bile acid derivative and self-assembling material, can be controlled ...
