Influence of Temperature on Scratch and Wear Properties of Technical Thermoplastics: Implications for Material Selection

Advanced Engineering Materials, EarlyView.
The share of technical thermoplastics is expected to grow further in the e‐mobility segment. In this study, a detailed temperature‐based tribological characterization of technical thermoplastics is performed. The tribological properties are discussed in terms of the dynamic mechanical properties of polymers at different ambient temperatures. A proof of

Borderline Aggregation Kinetics in ``Dry'' and ``Wet'' Environments

, 1995
We investigate the kinetics of constant-kernel aggregation which is augmented by either: (a) evaporation of monomers from finite-mass clusters, or (b) continuous cluster growth -- \ie, condensation. The rate equations for these two processes are analyzed

Femtosecond Single‐ and Double‐Pulse Fabrication of Periodic Nanostructures on Stainless Steel for Surface‐Enhanced Raman Spectroscopy

Advanced Engineering Materials, EarlyView.
Periodic submicron features are fabricated on 304 stainless steel using single and double femtosecond laser pulses. By adjusting polarization, fluence, and inter‐pulse delay, 1D and 2D nanostructures are formed. Enhanced hydrophobicity and dense surface‐enhanced Raman spectroscopy hotspots enable analyte detection down to 10−10 M with good ...

Tribology of ZrC Coatings and Spherical Tips Acquired with Extraordinarily Stiff, Metal Atomic Force Microscopy Probes

Advanced Engineering Materials, EarlyView.
In this research, ZrC coatings are evaluated against various counterprobes at the microscale using novel super‐stiff atomic force microscopy cantilevers. The chemical composition of the coating is shown to be an important factor influencing coating hardness and Young's modulus, while surface roughness, counterprobe hardness, and surface energy are the ...

Failure of Standard Thermodynamics in Planck Scale Black Hole System

, 2006
The final stage of the black hole evaporation is a matter of debates in the existing literature. In this paper, we consider this problem within two alternative approaches: noncommutative geometry(NCG) and the generalized uncertainty principle(GUP).

Future changes in precipitation over Central Asia based on CMIP6 projections

Environmental Research Letters, 2020
A stronger than global mean warming trend is projected over Central Asia in the coming century. Based on the historical simulations and projections under four combined scenarios of the Shared Socioeconomic Pathways and the Representative Concentration ...

Process Parameter and Dimension‐Dependent Mn Vaporization During Laser Powder Bed Fusion of an Fe–Mi–Si–Cr‐Based Shape Memory Alloy

Advanced Engineering Materials, EarlyView.
The functional properties of Fe–Mn–Si–Cr‐based shape memory alloys are influenced, among other things, by their chemical composition. Here, the vaporization of Mn, the most volatile element of the alloy, is investigated. It is shown that the process parameters make noninterchangeable contributions to the vaporization and that vaporization differences ...

Dual-species quantum degeneracy of potassium-40 and rubidium-87 on an atom chip

, 2006
In this article we review our recent experiments with a 40K-87Rb mixture. We demonstrate rapid sympathetic cooling of a 40K-87Rb mixture to dual quantum degeneracy on an atom chip.

Vacuum‐Formed Composites Based on a Polyolefin and a High Content of Biomass‐Waste Fillers

Advanced Engineering Materials, EarlyView.
It is shown here that by the use of a very ductile polymer matrix, it is possible to vacuum‐form products that contain up to 25% of hard biofillers with still ductile properties. The results are promising and opens up for the use of engineered biocomposites derived from industrial side‐stream biofillers in vacuum‐formed products. A strategy to increase
