Notice of retraction

Abstract

The editors of the KSCE Journal of Civil Engineering hereby retract the article "Field testing and capacity-ratings of a shortspan bridge superstructures made of advanced composite materials" by Hyo Seon Ji, Byung Jik Son, and Suk Yoon Chang, which was published in Volume 10, Number 2, March 2006, pp. 113-121. The article is retracted because relatively the same article "Field testing and capacity-ratings of advanced composite materials short-span bridge superstructures" by Hyo Seon Ji,

One‐step ultrasonic production of the chitosan/lactose/g‐C3N4 nanocomposites with lactose as a biological capping agent: Photocatalytic activity study

“…In addition to many benefits, chitosan has several obvious weaknesses, such as hydrophobicity, past biodegradation, and acidic degradation, which can be improved in PLA/chitosan. [ 31,32 ] In this study, ultrasound irradiation technique as a cost effective, simple, and safe method assistant with electrospinning process have been used for the preparation of the nanocomposites. Based on the literature, there is no report on using g‐C 3 N 4 in chitosan/lactose nanocomposites.…”
