ABOUT US

Physics Research Initiative (PRI) Pokhara is a group of researchers formed by academic faculties and young professional physicists with an aim to inspire young researcher and promote science literacy in general public. The three main areas of PRI are Research, Outreach, and Awareness on science and technology. PRI is working closely with Department of Physics at Prithvi Narayan Campus to conduct its various scientific programs. Since its inception in 2017, PRI has organized twenty one scientific talks in a series called “Scientific Discussion Series”; three workshops in to empower young researcher with computational techniques, three “Friday Science Social” programs; observation of “National Science Day” in Pokhara, and a couple of outreach program in a public library and in a secondary school. PRI has also formed a “Feynman Study Circle” to engage undergraduate physics students in learning and discussing “textbook” physics.

OUR MISSIONS

  • To motivate and encourage research culture.
  • Train young researcher in computational and other research skills in physics.
  • To bridge the gap between scientists and community via public outreach communication.
  • To promote scientific temper.

RECENT SCIENCE DISCUSSION SERIES (EPISODE-30)

A Study of the Occurrence Rate and Energy of Flares on M5-L5 Spectral Types

Abstract

Many different techniques are available to create nanopatterns in nanoscale devices. However, a few are flexible and inexpensive enough to be practical in the nanotechnology. Here, we study the nanosphere lithography (NSL) based on a self assembly of microspheres. Using this technique, we have developed various patterns in metallic films, ranging from honeycomb arrays of “quasi-triangles" to circular holes. These various patterns have been used subsequently either as nano optical structures directly, with remarkable optical and plasmonic properties, or as substrates for further nanoprocessing. In one such nano-processing, the “quasi-triangle” patterns were used as a catalyst for carbon nanotube growth. The resulting aligned arrays of carbon nanotubes were employed in nanocoax solar cells. In another nanoprocessing, the arrays were used as masks for electrodeposition. In addition to the nano processing and measurements, we have employed the FDTD computer simulations, to develop a full understanding of the nano optical and plasmonic properties of the developed structures.
