Introduction to Fractal Antenna
IJIREEICE, 2016 In this article, the most recent improvements in the field of fractal antenna designing are theoretically and additionally basically checked on and its future extension is talked about. Fractal design is a geometric example that is rehashed at each design and in this way can't be spoken to by exemplary geometry.

Advanced Science, EarlyView.Poly(vinyl alcohol)‐modified liquid‐metal particles form conductive networks through spray‐induced self‐fusion without additional post‐treatment. Spray impact initiates oxide‐shell rupture and electrical contact, while subsequent Marangoni flow and capillary forces promote particle redistribution, neck growth, and network consolidation. This sequential

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Enhancing oil recovery (EOR) in mature reservoirs is hindered by high interfacial tension (IFT) and oil‐wet rock formations, especially under harsh, high‐salinity conditions. This study aims to overcome these limitations by synthesizing a novel carbon nanotube nanocomposite covalently grafted with polyethylenimine and non‐covalently ...
