Abstract

Analysis of impurity in powder samples has been made by using metal-assisted laser-induced plasma spectroscopy utilizing a pulsed CO laser. Various powders including food powder, supplement powder, baby powder, and medicine powder were employed as sample materials. Experimentally, the powder sample was tightly put in a hole made on a metal plate and a metal mesh was placed on the powder surface. A pulse CO laser (10.6

μ

m, 1500 mJ) was irradiated on the powder surface passing through the metal mesh. Luminous plasma was induced by mesh just above the mesh when a part of laser energy attacked the mesh. The other part of laser energy impinged the powders and ablated fine particles of powder to the plasma to be atomized and excited. Identification and analysis of elements in powder were successfully conducted. A linear calibration curve of Cu in baby powder has been demonstrated with an intercept zero, certifying that the present technique was a high possibility to be employed for semi-quantitative analysis of elements in powder material. It was proved that by applying the present technique and employing a condensation technique, the detection sensitivity of Cr impurity in the powder sample increased about twenty times compared to the case without condensation. The limit of detection of Cr in rice powder sample was 25 mg/kg. The proposed method was very convenient for

Abstract

This research aims to investigate the effect of crude palm oil (CPO) as a plasticizer in polypropylene blown lm on thermal and dynamic mechanical properties. Polypropylene (PP) was blended with 1, 3, and 5% of CPO using a twin screw extruder. The extruded samples were blown using the blown thin lm technique. The samples were analyzed using dynamic mechanical analysis (DMA), differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). From the dynamic mechanical analysis, the storage modulus and loss modulus for PP presented decreasing pattern about 3–5% due to the action of CPO as plasticizer which introduced free volume and enabled the polyole ns chains to deform more easily. The glass transition temperatures (Tg) of PP were found being shifted to lower temperature from 10 to 1 °C with the increasing CPO content. The fraction of crystallization was determined using DSC. The thermogravimetric analysis (TGA) results showed that the incorporation of CPO as plasticizer showed a small increased effect in the thermal stability for PP. These ndings have contributed new knowledge to the additives area and give important implications for designing and manufacturing polymer packaging materials.

Abstract

The present study outlines the development and validation of a four-tier diagnostic instrument to explore rst year undergraduate students’

understanding of chemical kinetics (FTDICK). The four-tier instrument is a recent format and has been applied only sparsely in a limited number of subject areas, not including chemical kinetics. This study con rms the importance of a four-tier approach in fully investigating students’ poor knowledge and understanding. The FTDICK described here involves 20 questions with a con dence level linked to both the question tier and the reason tier. The development of the instrument followed the procedure used for the two-tier instrument developed by Treagust and involves (1) testing & interviewing, (2) identifying & collecting students’ unscienti c ideas, (3) developing the prototype FTDICK, (4) validating the prototype FTDICK, and (5) developing the nal FTDICK. The initial steps revealed a number of areas of misconceptions to be explored in the nal instrument. The instrument has been developed and the prototype tested using international cohorts of students from the University of Reading, UK and two Indonesian Universities. Comprehensive item analysis on the results showed the instrument to be valid and reliable and suitable for identifying students’ understanding of chemical kinetics. This study con rms the importance of a four-tier approach for investigating students’ prior knowledge and understanding.
