Active Site Determination of Heterogenized Molecular Electrocatalysts

Advanced Energy Materials, EarlyView.
Here, we develop a methodology to examine the active site availability of immobilized transition‐metal molecular complexes via cyclic voltammetry. By using varying loadings of the molecular complex FeTPP physically immobilized onto Vulcan Carbon, we show the influences of FeTPP/VC ratios on the total number of active sites.

Side Milling of Helical End Mill Oscillated in Axial Direction with Ultrasonic Vibration

International Journal of Automation Technology, 2019
This paper is focused on the cutting performance in the side milling of a small-size end mill with vibrations generated by an ultrasonic vibration spindle apparatus in the axial direction with a helix edge. In side milling with ultrasonic vibration in the rotational direction, the mean value of the cross-sectional chip area per cutting time decreases ...

Evidence for an anomalous current phase relation in topological insulator Josephson junctions

, 2015
Josephson junctions with topological insulator weak links can host low energy Andreev bound states giving rise to a current phase relation that deviates from sinusoidal behaviour.

The tool profile and the localization of the revolution axis for irregular outline milling

MATEC Web of Conferences, 2017
For the most cases of manufacturing cutting processes in today’s flexible manufacturing systems, the cutting tools which are needed are almost standard. The problem of choosing the appropriate tool shape and dimension is often made by the tool management

Numerical and Experimental Study of Mixing Characteristics in a Spiral Micromixer

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Significant enhancement of mixing performance can be achieved by Dean vortices in spiral channels. In order to deeply explore the mixing mechanisms and variation laws in spiral micromixers, this work designed a spiral micromixer and adopted a combined method of experiments and numerical simulations to analyze the mixing performance and ...

A perspective from the Mesozoic: Evolutionary changes of the mammalian skull and their influence on feeding efficiency and high‐frequency hearing

The Anatomical Record, EarlyView.
Abstract The complex evolutionary history behind modern mammalian chewing performance and hearing function is a result of several changes in the entire skeletomuscular system of the skull and lower jaw. Lately, exciting multifunctional 3D analytical methods and kinematic simulations of feeding functions in both modern and fossil mammals and their ...

Differences in predominant collagen fiber orientation between dorsal and plantar trabecular bone tracts of adult mule deer calcanei suggest strain‐mode‐specific adaptation

The Anatomical Record, EarlyView.
Polarized microscopic images of the outer bone cortex (a and b) and deeper trabecular bone (c and d) of the deer calcaneus in thin cross‐sections. The brighter gray levels reflect more oblique‐to‐transverse collagen fibers in the compression/dorsal bone (a, c) and the darker gray levels reflect more longitudinal collagen in the tension/plantar bone (b,
