Reduction of Micro‐Motion at the Tapered Connection of Hip Endoprostheses with an Adapted Deep Rolling Process of CoCrMo Inner Tapers

open access: yesAdvanced Materials Interfaces, EarlyView.
The ball burnishing processes demonstrated a notable reduction of surface roughness, which in turn helps to reduce the formation of wear particles and is reflected in the significantly reduced wear rate. The torsional resistance in the range of micro‐motion (≈2 Nm) can be improved by implementing a ball burnishing process with augmented depth hardness.

Bandgap Tuning of β‐(AlxGa1‐x)2O3 Nanosheets via Liquid Metal Interface Engineering

open access: yesAdvanced Optical Materials, EarlyView.
Ultrathin β‐(AlxGa1‐x)2O3 nanosheets with controlled composition are synthesized via low‐temperature squeeze‐printing of Al─Ga liquid alloys. Aluminium preferentially migrates to the surface of the liquid alloy, forming Al‐rich oxide layers with tunable bandgaps up to 6.4 eV. This compositionally precise approach enables the fabrication of 2D ultrawide‐

Simple unity among the fundamental equations of science

open access: yes, 2019
The Price equation describes the change in populations. Change concerns some value, such as biological fitness, information or physical work. The Price equation reveals universal aspects for the nature of change, independently of the meaning ascribed to ...

Design Method of Time‐Multiplexed Ultrashort Throw Ratio Projection System with Low Distortion and Uniform Resolution

open access: yesAdvanced Photonics Research, EarlyView.
This work develops an ultrashort throw ratio (UTR) laser projection system using time‐multiplexed micro electro mechanical systems scanning. Trapezoidal distortion via vertical laser incidence control is eliminated and a systematic design method integrating a miniaturized catadioptric objective that maintains uniform optical étendue is proposed.
