[ 1 ] - Optimization of the electrospinning process of polyurethane nanofibers and their filtration performance for use in respiratory protection mask filters
Background and Aim: Electrospun nanofibers can be used to produce filter media in personal protective equipment for the military. The present study aimed to optimize the electrospinning process used to create polyurethane nanofiber substrates and compare the optimum substrate filtration performance with a typical commercial substrate used in the structure of N95 respirators. Methods: In this ex...
[ 2 ] - Design and validation of a tool for measuring knowledge, attitude and practice (KAP) regarding chemical safety in laboratory
ABSTRACT Due to the increasing use of chemicals in academic laboratories, a tool to measure awareness of students regarding labeling, hazards and characteristics of chemicals is still needed. The aim of this study was to design and validate a questionnaire to the assessing student’s knowledge about chemical hazards. The present study was conducted in two stages of design and evaluation of val...
[ 3 ] - Development of a Method Based on the Needle-trap Microextraction Filled with Hydroxyapatite and Polyaniline Nanocomposite for Determination of Volatile Organic Compounds in the Air
In this study, the efficiency of packed needle trap with hydroxyapatite/polyaniline (NTD-HAP/PA) nanocomposite was assessed in air sampling and analysis of a hazardous group of VOCs such as benzene, toluene, ethylbenzene and xylenes. The effects of main parameters, including desorption temperature and time, were evaluated on the performance and carryover of prepared NTDs. Moreover, the repeatab...
