Effects of Carbon Nanoparticles on Triboelectro‐Induced Surface Defects
Carbon nanoparticles added to grease modify the electrocontact behavior. The synergy of particle concentration and electric current dominates the surface damage of metals in contact. Electrical surface damage caused by current leakage is a critical challenge in high‐performance applications such as electric vehicle (EV) drivetrains and wind turbine ...

Lunar rocks as meteoroid detectors [PDF]
About 5000 microcraters on seven lunar rocks recovered during the Apollo 12 mission have been systematically studied using a stereomicroscope. Based on comparisons with laboratory cratering experiments, at least 95 percent of all millimeter sized craters

Comparison of experimental and model‐predicted erosion rates for carbon fibre‐reinforced polymer (CFRP) and glass fibre‐reinforced polymer (GFRP) under low‐velocity (2 m/s) and at varying angles and sand concentrations (0.0, 0.05, 0.4 g/L). The results demonstrate good agreement between experimental data and model predictions across different erosive ...

Crater morphology and morphometry on the Uranian satellites [PDF]
Fresh craters on the icy Uranian satellites exhibit a range of morphologies similar to craters on the icy satellites of Jupiter and Saturn. The general structural features found in the craters are described.

Mesoporous Carbon Thin Films with Large Mesopores as Model Material for Electrochemical Applications
Mesoporous carbon thin films possessing 70 nm mesopores are prepared on titanium substrates by soft templating of resol resins with a self‐synthesized poly(ethylene oxide)‐block‐poly(hexyl acrylate) block copolymer. A strategy to avoid corrosion of the metal substrate is presented, and the films are extensively characterized in terms of morphology ...

ABSTRACT Mining is crucial to the development of developing countries. This article studies the perspective of Indigenous peoples of Fiji (iTaukei) on the impact of mining on their development. Considering Indigenous knowledge at the core of this research, a unique qualitative methodology that integrates Vakumuni Vuku ni Vanua (gathering wisdom of the ...

ABSTRACT Coronary perforations are a dreaded complication for any interventional cardiologist. The treatment of this complication is exceptionally difficult when it occurs in a coronary bifurcation. While a conservative approach or a balloon occlusion might be sufficient in some cases, additional treatment is sometimes necessary.

Simulation Tests on Granite Pillar Rockburst
Parallelepipeds specimens were made to further investigate the rockburst occurrence mechanism of ore pillars in underground mining units. The investigation was carried out with uniaxial compression systems and real-time testing systems, such as stress ...
