Comparative Wear and Friction Analysis of Sliding Surface Materials for Hydrostatic Bearing under Oil Supply Failure Conditions

Advanced Engineering Materials, EarlyView.
Hydrostatic bearings excel in high‐precision applications, but their performance hinges on a continuous external supply. This study evaluates various material combinations for sliding surfaces to mitigate damage during supply failures or misalignment and to discover the most effective materials identified for enhancing the reliability and efficiency of

18FDG production in a PET imaging using a proton flux produced by D-D fusion reaction

Basic & Clinical Cancer Research, 2022
Fluorine 18-deoxyglucose (18FDG) is often used in Positron Emission Tomography (PET). PET imaging is one of the useful tool which is used to cancer detection and management. PET growth is limited due to problems that depend on the production of Fluorine-

A Different Perspective on the Solid Lubrication Performance of Black Phosphorous: Friend or Foe?

Advanced Engineering Materials, EarlyView.
Researchers investigate black phosphorous (BP) as a standalone solid lubricant coating through ball‐on‐disc linear‐reciprocating sliding experiments in dry conditions. Testing on different metals shows BP doesn't universally reduce friction and wear. However, it achieves 33% friction reduction on rougher iron surfaces and 23% wear reduction on aluminum.

Surface Modification of Fluorine‐Free Superhydrophobic Materials with (Ultra‐)Thin TiO2 Layers

Advanced Engineering Materials, EarlyView.
Significant changes in wettability, with a reduction of 60o in the water conduct angle, are reported via the surface modification of fluorine‐free superhydrophobic thin films, prepared by aerosol‐assisted chemical vapor deposition, after coating a 4 nm layer of titanium dioxide on the surface using atomic layer deposition.

Stabilized Intermediate Phase Via Pseudo‐Halide Anions Toward Highly Efficient and Light‐Soaking Stable Perovskite Solar Cells

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
The formate pseudo‐halide anion is strategically introduced at the buried interface to stabilize the intermediate phases formed during perovskite crystallization. The controlled crystallization enhances crystallinity and alleviates tensile strain, eliminating residual PbI2 near the buried interface.
