**Meet the editors**

Dr. Sher Bahadar Khan received his PhD in chemistry from HEJ, Karachi University, Pakistan. After completion of his PhD, he began his postdoctoral career in nanochemistry and nanotechnology and continued to work as a postdoctoral research fellow until February 2010 at Yonsei University, South Korea. In March 2010, he joined the Center for Advanced Materials and Nano-engineer-

ing, Department of Chemistry, Najran University, as an assistant professor and continued his work until August 31, 2011. He joined the Chemistry Department, King Abdulaziz University, Jeddah, Saudi Arabia, as an assistant professor in September 2011. Currently, he is a full professor and conducting research into nanochemistry and nanotechnology, which comprises drug delivery, solar cells, development of active photocatalysts, and fabrication of perceptive biosensors and chemisensors using metal oxide nanomaterials and their green environmental nanohybrids. He is the author of six books, six patents, and 270 research papers with more than 800 impact factors, 4000 citations, and a 35 h-index.

Dr. Kalsoom Akhtar received her PhD from the Chemistry Department, Ewha Womans University, Seoul, Korea. Dr. Akhtar is an assistant professor at the Chemistry Department, King Abdulaziz University, and is conducting research into organic chemistry and nanochemistry, which comprises photocatalysts, organic synthesis, and metal oxide nanomaterials. She is the author of two books and 65 research papers.
