Flettner Rotor Concept for Marine Applications: A Systematic Study

open access: yes, 2016
The concept of Flettner rotor, a rotating cylinder immersed in a fluid current, with a top-mounted disk, has been analyzed by means of unsteady Reynolds averaged Navier-Stokes simulations, with the aim of creating a suitable tool for the preliminary ...

Apparatus and method for reducing thermal stress in a turbine rotor [PDF]

open access: yes, 1978
A gas turbine is described wherein the thermal stresses in the turbine rotor are reduced. The rotor includes a central disc with a peripheral rim, and a plurality of blades extending radially outward from the rim.

Symmetry Breaking in Meniscus Splitting: Effects of Boundary Conditions and Polymeric Membrane Growth

open access: yesAdvanced Science, EarlyView.
Meniscus splitting in the drying of a viscous polymer dispersion is investigated by focusing on nucleation of multiple nuclei with symmetry breaking and asynchronous nucleus formation. Controlled by spatial boundaries, the first nucleus is generated at a position shifted away from the space center and strongly facilitates the asynchronous second ...

High‐Throughput MicroED for Probing Ion Channel Dynamics

open access: yesAdvanced Science, EarlyView.
High‐throughput MicroED offers a new approach for visualizing ion channel dynamics. This approach reveals NaK’s sodium binding modes and NaK2CNG’s potassium‐induced selectivity filter dilation and gating. By capturing these distinct structures, this work challenges traditional models of ion channel permeation and selectivity. Abstract Ion channels play

DNA Sequential Logic Circuits for Reversible Counters and Dynamic Biomolecular Sensing

open access: yesAdvanced Science, EarlyView.
In this work, a DNA sequential logic circuit is constructed that combines reusability and autonomy for the first time, including SR (Set‐Reset)‐latches composed of NOR gates, SR‐latches composed of NAND gates, and D (Data)‐latches. After fully utilizing the characteristics of each latch, to counter, toxin and miRNA detection and intracellular dynamic ...
