Semicrystalline Block Copolymers in Rigid Confining Nanopores.

We have investigated PLLA crystallization in lamellae-forming PS--PLLA confined to straight cylindrical nanopores under weak confinement (nanopore diameter /equilibrium PS--PLLA period ≥ 4.8). Molten PS--PLLA predominantly forms concentric lamellae along the nanopores, but intertwined helices occur even for / ≈ 7.

Polymer dynamics under cylindrical confinement featuring a locally repulsive surface: A quasielastic neutron scattering study.

We investigated the effect of intermediate cylindrical confinement with locally repulsive walls on the segmental and entanglement dynamics of a polymer melt by quasielastic neutron scattering. As a reference, the corresponding polymer melt was measured under identical conditions. The locally repulsive confinement was realized by hydrophilic anodic alumina nanopores with a diameter of 20 nm.

Oxidized Mild Steel S235: An Efficient Anode for Electrocatalytically Initiated Water Splitting.

The surface of steel S235 was oxidized by Cl2 gas and checked for its electrocatalytic efficiency regarding oxygen formation in aqueous solution. If exposed to humid Cl2 gas for 110 min, steel S235 became an electrocatalyst that exhibits an overpotential for the oxygen evolution reaction (OER) of 462 mV at 1 mA cm(-2) at pH 7. The OER activity of the same sample at pH 13 was moderate (347 mV overpotential at 2.
