Abstract

The term “oxidation number” and related concept such as “electronegativity” and “formal charge” appear frequently in both elementary and advance chemistry text. However, it is evident from the literature (or textbooks) that these terms are often viewed to be synonymous. Incomplete explanation of the fundamental concept of oxidation number can lead that conclusions pertaining to such a misleading interpretation. This research was conducted to review the concepts from common used high school chemistry textbooks and these concepts were then transformed to 6 number open minded problems. These problems were then tested to 40 first semester chemistry program students in the University of Jambi who joining Basic Chemistry course. The result was about 80% of students give the right answer in determining oxidation number (problem number 1). But, in the certain molecule (problem number 2) they can’t determine correctly because they couldn’t use the “Rule” from initial understanding in high school. For the next problem (4a), none of the students give the right oxidation number of an atom and all of them can’t explain precisely correlation among oxidation number, electronegativity, and formal charge. The intent of this paper is to clarify the notion of oxidation number, electronegativity, and formal charge, describe their relationship (especially for high school chemistry textbooks), and criticize upon misleading application.

Abstract

Based on an extended theory of planned behavior (TPB), this study focused on five exogenous constructs (perceived benefits, facilitating condition, normative belief, behavioral belief, and control belief) that was established to predict behavioral intention and behavior of data-sharing. The research model was tested with 157 Indonesian researchers from science, technology, engineering, and mathematics (STEM). We applied the partial least squares (PLS) techniques to analyze the data. Seven out of eleven hypotheses are supported based on the significance test in through the PLS-SEM procedure. The study’s findings show that the proposed extended TPB is a valid and reliable framework for describing the data-sharing behavior of STEM researchers. This paper facilitates an advanced investigation through PLS-SEM approaches toward behavioral intention and behavior regarding data-sharing; the findings are among the first elaborated data-sharing report in the Indonesian context, a country with more than 200 thousand researchers.

Abstract

The powerful performance of TiO2 and its doped as photocatalyst material initiated the finding of new technique that efficient and effective to degrade the organic pollutant, i.e., azo dyes. This study examined photocatalyst film's photoactivity, TEMPO-oxidized cellulose-containing N-TiO2 (TOC/N-TiO2), on the degradation of azo dyes. TEMPO-oxidized cellulose, which has a negative charge, was sequentially mixed and stirred in the suspension of TiO2 and doped TiO2. This experiment utilized several instruments to determine the physicochemical properties of the photocatalyst film. The UV-DRS and diffractogram data confirmed the anatase phase as the only phase found in N-TiO2, which has a lower bandgap value than the anatase TiO2. These data demonstrated the superior photocatalytic of TOC/ N-TiO2 against azo dyes.Keywords: Doped-TiO2; Film; Photocatalyst; TEMPO-oxidized cellulose nanofiber

Abstract

The food freshness is one trending topic that currently studied to reduce the number of food waste. The development of food freshness film indicator is one technique that can be utilized to resolve the high number of food waste. The objective of this study was to evaluate the ability of cellulose nanofiber film that had been integrated with anthocyanine as the food freshness film indicator. Cellulose nanofiber was obtained from empty fruit bunch of palm oil that had been dried, cut, and milled into fine powder. The initial step of this preparation was bleaching process using NaOCl/NH3 and H2O2/NH3. After bleaching process, cellulose fiber was oxidized using TEMPO/NaOCl/NaBr at pH 10 for 6 h. The TEMPO-oxidized cellulose fiber was then transferred into high pressure-homogenizer for 6-cycles at 800 bar of pressure. The cellulose nanofiber was obtained as hydrated fiber (gel-like) and then combined with anthocyanine obtaining from red cabbage extract, the film was casted on the acrylic plate. The film indicator of cellulose nanofiber was analyzed to determine the characteristic of film, i.e., color stability depending on pH, morphology, mechanical properties, and color response of film on the food freshness. The film of cellulose nanofiber that integrated with anthocyanin extract has the good sensitiveness to test the food freshness at 4oC. The color change produced by this indicator film is quite significant and has a different color at each pH value.
