Bimetallic (NiFe) and Trimetallic (NiFeCr) Nanoalloys from Metal Oxides Using a Microwave Hydrogen Plasma

Advanced Engineering Materials, EarlyView.
Bimetallic (NiFe) and trimetallic (NiFeCr) nanoalloys (NAs) are synthesized using corresponding oxide mixtures using microwave hydrogen plasma within a few milliseconds. The process simultaneously 1) reduces metal oxides to metals; 2) downsizes the particles from micrometers to nanometers; and 3) blends the metals to form NAs.

GAN based Underwater Image Enhancement

, 2023
Underwater image enhancement has drawn a lot of attention because of its significance in marine engineering and aquatic robotics. Many techniques for enhancing underwater photographs have been put forth in recent years. Since light propagation underwater and in the atmosphere are different, a particular set of nonlinear visual distortions occur.
